Is New Hampshire on the verge of battery energy storage history?


Is New Hampshire on the verge of battery energy storage history?

The only question left to be settled is a big one: Should utilities own behind-the-meter batteries?

A small investor-owned utility in New Hampshire may be on the verge of regulatory approval for one of the most ambitious U.S. tests yet of utility-owned, customer-sited battery energy storage systems.

In the process, regulators and stakeholders of the DE 17-189 proceeding are wrestling with a question of vital interest to the rest of the 3,000-plus U.S. utilities: Should a utility own customer-sited storage or is it a distributed energy resource (DER) that should be left to private sector providers?

Utilities have already seen the benefits that large-scale battery energy storage offers in shaving peak demand, providing grid services, and making systems more flexible. There is a clear opportunity to use customer-sited battery storage in the same way. But the question of how far utilities can intrude into markets so far served by private sector vendors must first be answered.

Vermont goes first

The only major U.S. utility-owned, behind-the-meter (BTM) battery storage is the Green Mountain Power (GMP) pilot project, according to GTM Research Energy Storage Analyst Brett Simon. GMP, the dominant Vermont electricity provider, is installing 2,000 behind-the-meter Tesla Powerwalls that will provide dispatchable energy and other grid services to New England’s wholesale electricity markets. Customers pay a one-time $1,300 fee or a monthly $15 fee to participate.

How solar power could become a victim of its own success

Solar plant in Bavaria, Germany


Solar is the world’s fastest growing source of new energy, outpacing growth in all other forms of renewable energy, according to research by the International Energy Agency (IEA) published in November. Renewables overall accounted for two thirds of new power added to the world’s grids in 2016, and solar even overtook coal in terms of net growth. This enormous boost has come about thanks in part to the plummeting costs of getting rigged up to wind and solar, as well as massive growth in China and India.

Good times, then, for the Earth’s long-term prospects of continuing to power itself, and taper the consumption of fossil fuels. At the end of April, 85 per cent of German electricity came from renewable sources, establishing a new national record for the country, with breezy, warm and sunny weather combining to create a renewable whammy of unseen proportions.

Last week, solar overtook biomass to become the third source of renewable energy in the US, and renewables in the country now provide 17 per cent of overall electricity, marking good progress, though there is still a way to go with solar only constituting one per cent. Read More

Hawaii just passed a law to make the state carbon neutral by 2045


In a little less than three decades, Hawaii plans to be carbon neutral–the most ambitious climate goal in the United States. Governor David Ige signed a bill today committing to make the state fully carbon neutral by 2045, along with a second bill that will use carbon offsets to help fund planting trees throughout Hawaii. A third bill requires new building projects to consider how high sea levels will rise in their engineering decisions.

The state is especially vulnerable to climate change–sea level rise, for example, threatens to cause $19 billion in economic losses–and that’s one of the reasons that the new laws had support. “We’re on the forefront of climate change impacts,” says Scott Glenn, who leads the state’s environmental quality office. “We experience it directly and we’re a small island. People feel the trade wind days becoming less. They notice the changes in rain. They feel it getting hotter. Because we are directly exposed to this, there’s no denying it.” The state’s political leaders, he says, are “unified in acknowledging that climate change is real and that we do need to do something about it.” Read More

Solar power plant deal signed

A massive solar power plant is to be built on a vacant runway at the airport.

Saturn Solar Bermuda 1, a part of Canadian-based Saturn Power, will develop the six-megawatt power plant on “the finger”, a runway and munitions pier when the airport was run by the US Navy as a Naval Air Station.

The generating plant will be the first large-scale renewable energy resource on the island.

Walter Roban, the Minister of Transport and Regulatory Affairs, said: “Out of nine candidates, six being Bermudian, Saturn Power came in as the lowest bidder at 10.3 cents per kilowatt hour.

Why Solar Power Needs to Get Better:

Elon Musk

9 Experts on the Improvements Solar Technology Needs Today - Interesting Engineering

Solar is just one of many sustainable energies that could lead the way to a green power revolution. Though solar power is becoming more and more viable every day, there are still issues to overcome before entire countries can depend on the sun as a source of energy.
If we're to finally phase out fossil fuels for good, solar power needs to get better. Here are just some of the issues that experts are trying to address in the fight to make the world a greener place.

1. Elon Musk: Solar Power Needs to be Integrated
Elon Musk's vision of a solar-powered future doesn't stop at solar panels on roofs - he wants entire integrated systems to dominate homes and businesses all over the world. He imagines a future where solar roofing tiles feed into power walls, which in turn power electric cars.
Speaking in 2016, Musk said, "The key is it needs to be beautiful, affordable and seamlessly integrated." His point is clear - if solar power is to become a dominant power source, there has to be integrated infrastructure both privately and publicly to support that generation of energy. Read More

Distributed Solar Is Less Expensive Than Delivered Coal Power


On March 22, 2017, Rocky Mountain Institute’s Shine Program released a request for proposals (RFP) for community-scale solar on behalf of a group of rural electric cooperatives in eastern and northern Colorado. The RFP was part of RMI’s ongoing work to develop the community-scale market nationwide.

Nearly 30 developers responded to the RFP, providing highly competitive bids. Prices for solar power purchase agreements were lower than the value of solar to the co-ops, and so solar is expected to result in economic savings for participating co-ops.

RFP results confirm that we have crossed a significant tipping point where distributed solar is not only a means to supply green energy and to promote regional economic development, but also an opportunity to decrease energy costs and to drive down bills for price-sensitive energy consumers. The Colorado RFP outcomes are informative to utilities nationwide, but particularly to co-ops and municipal utilities in Colorado and neighboring states that are contemplating solar development and are interested in joining a regional procurement opportunity.

Could the entire American economy run on renewable energy alone?

Fisticuffs Over the Route to a Clean-Energy Future - The New York Times

This may seem like an irrelevant question, given that both the White House and Congress are controlled by a party that rejects the scientific consensus about human-driven climate change. But the proposition that it could, long a dream of an environmental movement as wary of nuclear energy as it is of fossil fuels, has been gaining ground among policy makers committed to reducing the nation’s carbon footprint. Democrats in both the United States Senate and in the California Assembly have proposed legislation this year calling for a full transition to renewable energy sources.

They are relying on what looks like a watertight scholarly analysis to support their call: the work of a prominent energy systems engineer from Stanford University, Mark Z. Jacobson. With three co-authors, he published a widely heralded article two years ago asserting that it would be eminently feasible to power the American economy by midcentury almost entirely with energy from the wind, the sun and water. What’s more, it would be cheaper than running it on fossil fuels.

The Caribbean Transitional Energy Conference (CTEC)


Caribbean economies suffer from some of the highest electricity prices in the world.

Despite their abundance of renewable energy sources, Cayman has a relatively low level of renewable energy penetration; the economy continues to spend a large proportion of its GDP on imported fossil fuels and residents and businesses continue to pay some of the highest electricity bills in the region. This is a common situation among island nations.

There is a clear opportunity for Cayman to emerge as a regional leader in developing solutions to address climate change through the adoption of renewable energy which will reduce the dependency on fossil fuels and provide key environmental, social and economic benefits.

With the Cayman Islands National Energy Policy now in place, a framework for transition is complete and seizing upon that vision will be critical to affecting positive change for the Cayman Islands and all those who follow.

The recent achievements for islands at COP21 provide a strong driver for action focused on carbon reduction goals. Given that Cayman ranks highly among islands as carbon emitters, it is critical that we position ourselves as leaders in carbon reduction and meet the goals set out in the National Energy Policy and the Paris agreement.

Cayman seeks to stand with other islands in the region and across the world to embrace a low carbon future and to stand on the front line of demonstrating solutions to climate change while delivering cheaper, secure, reliable and economically feasible energy solutions.
Who should attend?

Be part of Cayman’s low carbon future by joining an event which seeks to set out our vision, renewable road-map and opportunities.

SE4All Highlights Plans for Implementing SDG 7

25 March 2016: The Special Representative of the UN Secretary-General (SRSG) for Sustainable Energy for All (SE4All), Rachel Kyte, highlighted challenges to achieving Sustainable Development Goal (SDG) 7 (Ensure access to affordable, reliable, sustainable and modern energy for all).

Briefing UN Member States and civil society, she also provided an update on the SE4All initiative's plans for supporting implementation of the Goal.

Kyte emphasized that Goal 7 has three “pillars,” addressing energy poverty, technological advancement, and investment in energy efficiency. Stressing the interlinked nature of the Goal, she said the first pillar, addressing energy poverty, is essential to leaving no one behind, noting that the electricity access gap undermines education, productivity and economic growth, while the gap in access to clean cooking fuels is detrimental to health and gender inequality. On technological advancement, Kyte noted the past decade's reductions in the cost and complexity of renewable energy, which makes on-shore wind, solar photo voltaic, and other technologies more competitive with fossil-based energy sources. On energy efficiency, she said greater investment has made it possible to provide basic electricity services using much less power.

Despite this positive progress, Kyte warned that global economic trends have slowed the momentum for electrification, renewables, efficiency and clean cooking. She said the global energy transition is not taking place at a sufficient pace to meet the temperature goal set out in the Paris Agreement on climate change, or the broader development goals expressed in the 2030 Agenda.

Kyte also stressed that the financial needs to achieve SDG 7, which are estimated at over US$1 trillion annually, will need to come from both private and public sectors. She highlighted the importance of small-scale, private investments to develop renewable energy in many African countries.

On the role of the SE4All initiative in supporting the achievement of SDG 7, Kyte said the Forum's 2017 meeting will assess progress and provide substance for the High-level Political Forum on sustainable development (HLPF) and the UN system as a whole in its review of progress towards the SDGs. In the meantime, SE4All is developing a framework for addressing challenges faced by Member States in achieving SDG 7. Member States will have opportunities to provide input on this framework throughout May 2016, Kyte said, and the SE4All Advisory Board will consider the framework at its meeting, on 15-16 June 2016.

3 Ways Wind and Solar Can Continue To Grow In a 21st-Century Grid

Earlier this year, MIT researchers were the latest in a series of analysts to raise alarm about the perceived limitations of solar PV’s continued growth. In short, these analysts propose that variable renewables will depress wholesale prices when they run, thereby limiting their own economic success.

These concerns have garnered coverage in other venues (including Vox, Greentech Media, and The Financial Times), leading observers to suggest that the future prospects for renewables may be dim.

But are these concerns really justified, or do they rely on outdated assumptions about the grid and about electricity markets? We argue that these critiques, assuming a static grid and unchanging market mechanisms, can be used to make any innovation look bad. However, more integrative assessments of a least-cost, clean, and reliable power system of the future will factor in high fractions of variable renewables, along with more-efficient markets (and usage) and new technologies to integrate these resources seamlessly and resiliently.

In this article, we argue that falling wholesale prices is a good problem to have, and that concerns about economic limitations ignore remedies available from supply-side evolution, demand-side resources, and updated market mechanisms. As the world gathers in Paris for COP21, these messages are as important as ever for charting and pursuing a low-carbon clean-energy pathway.

Understanding the "Problems"

There has been increasing concern that variable renewables such as wind and solar may face an upper limit to adoption in the U.S. grid. The argument is that large amounts of variable renewables will create excess supply concentrated at the particular times of day when they produce. The notorious "duck curve" is an example of this—the duck-like shape of a particular, daily demand curve modeled for California’s grid when the production of large amounts of solar photovoltaics (PV) is netted out.

Critics argue that this technical characteristic of variable renewables, specifically PV—a daily generation pattern that is not perfectly matched with load—can have economic consequences for all forms of generators, especially the renewable resources themselves. Large amounts of renewable resources can sell a glut of power when it’s available, offsetting production from higher-marginal-cost resources (like gas-fired power plants). Since power prices are generally set by the resources with the highest marginal cost that clear in the market, additional generation from renewables tends to lower market prices.

This "merit order effect" often decreases revenues for fossil generators. This impact has been particularly dramatic in Europe, where generation from costly-to-run thermal plants during the daily solar peak was formerly very profitable for fossil generation owners. PV has decreased energy prices so much there that the top 10 EU utilities lost half their market capitalization. However, the merit order effect also means that variable renewables themselves may also earn lower profits as their adoption rises. A common conclusion is that variable renewables can play only a modest role in power production, marginalized by declining wholesale value at higher adoption levels.

The Other Half of the Thought Experiment: Three Factors That Can Accelerate Renewable Energy Adoption

Analysts who have put forth these arguments have elaborated only the first half of a microeconomics thought experiment. The problems they hypothesize hinge upon the laws of supply and demand, but omit important aspects of both, drastically overstating the perceived "problems." Let’s see how.

1) Supply is changing holistically, not incrementally

Many of these thought experiments consider adding just a single supply resource (often solar PV) without considering many of the other supply-side changes happening at the same time. In reality, solar PV, wind, and natural gas are all joining the supply mix in a big way at the same time; the first two are often complementary and the third is dispatchable, so together, they can do a lot to mitigate the "duck curve" often portrayed.

At the same time, retirements of uneconomic assets will provide a countervailing buoyancy to wholesale prices. For example, even though old, dirty plants often have low production costs, they may exit the market anyway due to high costs of compliance upgrades or other fixed costs that erode their profits. The resulting less-abundant supply can cause the marginal supply curve to contract in quantity, leading to higher prices and higher profits for renewables and remaining fossil generators—unless demand drops too, as it’s doing in the industrialized world.

2) Demand is increasingly flexible, not fixed

Analysts arguing that renewables’ variability will limit their growth often assume perfectly efficient wholesale markets, but unchanged retail markets and fixed demand profiles. This incomplete and asymmetrical treatment ignores the emerging capability to harness the demand side of the equation. For example, people like and respond to time-varying pricing programs, and these programs are starting to roll out at scale. The electricity demand of many appliances including electric water heaters and electric vehicles is inherently flexible without disrupting the service provided. Furthermore, new business models (from both utilities and third parties) are driving this convenient flexibility by providing seamless solutions, unobtrusively, conveniently, and without requiring customers to become part-time energy traders.

These factors together increase flexibility of demand, an important low-cost resource, and enable what is the most natural response to changing prices in an efficient market where consumers find ways to use and benefit from cheap electricity from wind and solar. In other words, as renewables reduce energy prices during certain times of day, demand flexibility allows customers to shift demand to those times, which will both reduce energy prices at other (peak) times and raise the price paid to renewables during times when they produce the most.

3) Storage makes renewables dispatchable, not variable

Diverse supply and flexible demand will play a big role in easing renewable integration concerns but, to the extent that issues remain, the continuing decline in battery prices and the range of values available from batteries means that remaining variability issues can probably be addressed at modest incremental costs. At the retail level, this can lead to increasing self-balancing of distributed generation (we’ve already seen this in Germany and Australia, and it may affect utility business models in the U.S.). At the wholesale level, as variable resources begin to saturate the market, high-priced hours will incentivize developers to begin to look at storage. Already, storage is seen as a near-term replacement for peaking generation, and batteries installed for peaking capacity can also be used to smooth the economic impact of renewables on power prices.

Storage is already a common feature of concentrating solar power (via molten salt), and becoming an increasingly common feature of solar PV. For example, the all-renewable winning bids in the latest Chilean auction for unsubsidized electricity included not just solar power as low as $65/MWh in the daytime, but also nighttime solar power—via thermal or electrical storage—for $97/MWh at night. With storage, variable renewables become dispatchable, and dispatchable renewables do not have nearly the same merit order effect as variable ones. To be sure, our recent demonstration that 13 kinds of benefits of behind-the-meter distributed storage can make batteries cost-effective does not necessarily make them competitive with the many other ways to achieve grid flexibility, but similar reasoning suggests an abundant range of options for averting the problems that narrowly constrained models imply.

Whole-System Thinking Illuminates a Path Towards Least-Cost Outcomes

Analysts arguing that renewables will economically limit their own continuing adoption generally leave out the considerations listed above—and more importantly, these arguments are built on incremental thinking, assuming that today’s grid and markets are fixed and only one thing changes (e.g., PV or wind-energy market share). A more holistic, integrative, and accurate analysis would start with the ultimate objectives (reliable, resilient, and least-cost energy services), and promote a whole-system design to get there promptly.

With this perspective in mind, the characteristics of renewable energy that have caused so much hand-wringing—variable output and near-zero marginal costs of production—simply add to the list of design considerations for a market design that rewards efficient investment. Given supply diversity, demand flexibility, and emerging technologies like storage, variable renewables are unlikely to face any practical limit to growth even under current grid paradigms and market structures.

Nothing Sacred About Existing Markets

But even if renewables do face adoption limits in current markets, there is no reason we have to keep these markets the way they are. Wholesale power markets are largely a product of historical coincidence, formed out of the paradigms of the last century in which thermal power plants competed only with each other. Modern market design that reflects the realities and changing resource mix of the 21st century grid, being pioneered in Germany already, can go a long way towards aligning incentives for least-cost resource mixes. Particularly, incorporating behind-the-meter distributed energy resources and flexible loads into energy markets—as is being done in California and New York—can bring new capabilities and a refined level of control to the grid.

An Integration Challenge?

Evolving supply, flexible demand, storage, and updated markets can remove the limits to increasing renewable energy on the grid. In a later post, we will highlight how these same levers can address the common concerns—and misunderstandings—about "integration costs" of renewable energy. For example, a much-hyped recent paper claims that high-penetration renewables must incur steeply rising integration costs. But that turns out to be an artifact of extremely restrictive assumptions in the models used, combined with an assertion that competitive harm to thermal-plant incumbents is an economic cost of the renewables that beat them.

Renewables Are Here To Stay

The "problems" with renewables often brought up by analysts may be real in isolation, but are overstated when the full range of options is considered. Indeed, these are good problems to have: they’re the natural forces of supply and demand acting to send signals to market participants to diversify resource choice, incentivize demand flexibility, and invest in storage and other emerging technologies. Arguments against wind and solar PV conclude that these resources will need greater subsidies to survive in the "duck curve" era. But instead, we can tap the latent power of supply diversity, demand flexibility, storage, and market design to level the playing field for all resources, rather than clinging to the premises of the 20th century grid. Protecting the old system is far inferior to enabling the new one so that innovation can flourish, entrepreneurs can thrive, and all options can compete fully and fairly. Source

Solar panels empower indigenous people in Canada's north

BEHCHOKO, Northwest Territories, Canada, Oct 26 (Thomson Reuters Foundation) - Daniel T’seleie, an indigenous activist in Canada’s far north, is campaigning to help his people wean themselves from a worrying dependence on imported fuel and food, recover old traditions and win greater autonomy from the government.

Daniel T’seleie

In a region with nearly 24 hours of daylight in the summer, one way to help meet his goals seems obvious: more solar power.

“Right now a lot of communities in the Northwest Territories are dependent on diesel-generated electricity, along with store-bought food,” said T’seleie in an open air interview near Behchoko, a clutch of small wooden houses nestled along the shores of Great Slave Lake.

Standing beside spindly jack pine trees growing from thin soil on the hard granite rock that covers much of northern Canada, T’seleie sees renewable energy as the force which could respond to the region’s complex, intertwined challenges.

Canada’s north is particularly vulnerable to global warming, which is making it harder for indigenous people to continue their traditions of hunting and trapping on the land, as ice sheets melt and caribou herds collapse.

And although indigenous people want what they call a “nation to nation” relationship with the Canadian government, they largely depend on it for diesel fuel in order to keep warm.

By harnessing renewable energy, T’seleie believes indigenous communities could gain more freedom from the state and revive ancient cultural practices, while doing their part to combat climate change which is hitting them particularly hard.

“Any way that communities can produce energy at a local level produces independence,” said the 34-year-old, sporting a baseball cap and jeans, the informal dress common in Canada’s rugged north.

SOLAR SURGE

The Northwest Territories has seen a surge in the use of solar power over the last five years, after the regional government spent about $50 million to boost renewable energy production and improve efficiency, said Jim Sparling, the territory’s senior climate change manager.

“On a per capita basis, we are second only to Ontario (Canada’s most populous province) for installed solar capacity,” Sparling told the Thomson Reuters Foundation in the territorial capital Yellowknife.

The huge and sparsely populated northern territory has fewer than 50,000 residents, about half of whom are indigenous, many from the Dene Nation, a tribal people who traditionally hunt caribou.

Solar power still represents a fairly small part of its energy consumption, though the level is rising, said Sparling.

Private individuals and companies in the territory are also installing solar panels on their own to try and bring down their energy bills and cut dependence on imports, he said.

That combination of rising use of renewable and better energy efficiency has allowed the province to hold its climate-changing emissions stable at 2005 levels despite a rise in the population and a growing economy, Sparling said.

The territorial government plans to be part of a Canadian delegation going to Paris for a U.N. climate summit in December, aimed at reaching a new global agreement on climate change.

Average temperatures in parts of the northern territory have already risen more than 3 degrees from pre-industrial levels, Sparling said.

Scientists say average world temperatures should not rise more 2 degrees if the world is to avoid the worst disasters associated with global warming.

“We have to scale up the ambition,” Sparling said. “We are very vulnerable if this problem gets worse.”

SWITCH OVER

North of the Arctic Circle, the village of Colville Lake, with fewer than 200 residents, is in the midst of a major switch from diesel power to solar.

Last year, the mostly indigenous community faced weekly power outages. But after a new solar power system was set-up, the area is now nearly self sufficient in electricity production during summer months when the sun shines almost round the clock.

It still needs to import fuel for the winter, but officials believe the new investments will lead to a 30 percent drop in diesel consumption, helping the environment and saving money.

Other small northern towns are looking to mimic the project to save cash and allow people to maintain traditional lifestyles by being less dependent on expensive imports.

“In the last 10 to 15 years there has been a huge push from (indigenous) communities to try and support themselves,” said Ashlee Cunsolo Willox, an indigenous studies professor at Cape Breton University and a researcher on climate change impacts.

As global warming leads to the thinning of Arctic sea ice and changes in the habits of northern animals, the region’s indigenous inhabitants are struggling to adapt their lifestyles while holding onto old traditions, she said.

The caribou population has collapsed in parts of the territory in a development experts link to climate change, and melting ice makes it harder for hunters to navigate the land in search of other animals to hunt.

“The north is the fastest changing geography in the world,” Cunsolo Willox said in a phone interview. “There is a lot of concern that traditional knowledge and skills will be lost with climate change.”

OLD TRADITIONS, NEW TECHNOLOGIES

Building greater self sufficiency - including by adapting cleaner, cheaper energy - may be a strategy for holding onto the old ways, activists say.

T’seleie, a law school graduate, said he previously tried to work through Canada’s court system and treaty negotiations to win greater autonomy for his people, after what he considers years of colonial abuses.

In the 1920s, Canadian colonial administrators declared the government’s aim was to “get rid of the Indian problem” by ending indigenous cultural practices, corralling the population into reserves and forcing aboriginal children into grim residential schools.

Canada’s government signed treaties with many indigenous groups, often in return for political support during periods of conflict, granting them access to parts of the land they once controlled and other benefits.

But many legal scholars and historians say the government did not honor those agreements in good faith.

After becoming disillusioned with the legal process, T’seleie decided working towards greater self-sufficiency in food and energy was the best way forward.

T’seleie is part of the first generation of indigenous people not forced to attend residential schools usually run by religious groups in other parts of Canada which took children from their parents, and forced them to speak English rather than native languages as a means of assimilation.

Sexual and physical abuse were rife at the institutions, the government now admits following years of litigation.

Health experts and indigenous leaders believe the legacy from these schools - including that many parents never learned how to raise children, as they were taken from their own parents - partially explain high rates of substance abuse, family violence and poverty in some indigenous communities.

Allowing people to stay on their ancestral land, continuing hunting and trapping practices, and learning stories and traditions from community elders are key to overcoming these problems, said Cunsolo Willox.

To support traditional practices and allow indigenous communities to live off the land as they have done for centuries, they need access to renewable energy, T’seleie said.

“A huge aspect of our lives, culture and language is lost when we can’t be on the land,” he said. “For me, that’s one of the biggest threats of climate change.” More

How Demand Flexibility Can Help Rooftop Solar Beat Demand Charges in Arizona

The debate over rooftop solar has grown increasingly contentious, pitting solar PV companies against utilities in many parts of the country. But nowhere has the debate been more heated than in sunny Arizona, where many customers have flocked to rooftop solar as prices have come down in recent years. Most recently, utility Salt River Project (SRP) has introduced a demand charge for solar customers.

Already common among commercial rate structures but much less so among residential, a demand charge is a component of the overall bill based on a customer’s maximum demand (kW) each month, in addition to more-traditional charges based on total consumption (kWh).

SRP argues that it needs to recover costs from its solar customers that they impose on the grid through high demand. The utility position is that solar customers use the grid in much the same way as non-solar customers, and impose similar costs. Yet traditional rates coupled with existing net energy metering (NEM) riders mean that solar customers pay much less per month than other customers. SRP’s new rate is designed to recover the difference by imposing a charge on a customer’s peak demand each month, which generally occurs after the sun sets.

However, solar companies and others claim that this pricing structure is unfair. The largest PV developer in the U.S., SolarCity, has sued the utility, arguing that SRP is practicing anti-competitive behavior. In any case, whether the new rate is fair or unfair, it means that the PV market is growing much more slowly in SRP than it was a year ago; interconnect requests have More

Fortis anti-green position reopens other issues

A recent press release from Canadian-owned utility Fortis TCI, contradicting an earlier pronouncement by the Rufus Ewing-led government that the company was considering a change in part from inefficient diesel generation to renewable or green energy, has reopened debate on a number of related issues, including the cost of electricity in the TCI and the relationship between successive TCI governments and Canadian firms.

Fortis TCI headquarters in Providenciales

Fortis Inc. is the largest investor-owned gas and electric distribution utility in Canada. Its regulated utilities account for 90 percent of total assets and serve more than 2.4 million customers across Canada and in New York State and the Caribbean – Belize, Cayman Islands and the TCI.


In 2011, the government of Belize expropriated the approximately 70% ownership interest of Fortis Inc. in Belize Electricity Ltd (BEL) an integrated electric utility and the principal distributor in Belize.

Fortis still owns Belize Electric Company Limited (BECOL), a non-regulated hydroelectric generation business that operates three hydroelectric generating facilities in Belize. There is an ongoing controversy over a secret and possibly unenforceable agreement between the then government of Belize and Fortis over alleged pre-emption rights in relation to national waterways.

In 2013, in opposing a proposed $1.5 billion acquisition of CH Energy Group in New York, a local grassroots group pointed to what they say is Fortis’ poor record in dealing with projects in Belize and British Columbia and citing "misinformation and a lack of trust" on the part of Fortis.

Meanwhile, Fortis TCI has possibly the highest cost of electricity in the western hemisphere and five times higher than those charged by the closest mainland utility Florida Power and Light (FPL). Further, the company returns to its Canadian parent a profit averaging $1,000 per year per household from a customer base numbering only 9,000 consumers, which equates to more than $80 per month per household in pure profit.

Notwithstanding the extraordinarily high profit margins enjoyed by Fortis, the company is permitted to import supplies and equipment duty free and constantly upgrades its distribution system in order to lower its long term costs.

While the internal operating statements of Fortis TCI have yet to be made public, it has long been suspected that the utility uses accelerated depreciation to write off capital expenditures quickly and therefore reduce their publicly reported profits. US accounting practices require that capital equipment and assets be depreciated more closely in line with the life expectancy of the asset, reducing the annual write off and therefore showing a more accurate, and possibly higher net profit.

The latest Fortis policy on renewable energy sources puts a halt to the hope of generating power from wind energy from the prevailing trade winds or from solar panels.

Fortis defended its new position on a reported failure of German green power efforts. However, Germany is a northern European country with far less solar energy available, which in spite of huge labour costs and social benefits is now expected to raise its electricity rates to less than $0.09 per Kwh or just 1/6th the cost of Fortis power.

Fortis purchased the former assets of Provo Power Company (PPC) in 2006, three years after the PNP came to power in a 2003 by-election. At the time of the purchase, then premier Michael Misick denied any knowledge of the buyout saying he had nothing to do with the buyout and could not forecast the fate of the employees. However, the stamp duty on the purchase would have yielded the country upwards of $9 million and was subject to negotiation with the Misick government and undoubtedly Misick himself.

At the time of the buyout, PPC was charging $0.26 per Kwh and now Fortis charges an additional surcharge that almost doubles the old rate to $0.51 per Kwh.

Last year, during the first year of the newly elected Progressive National Party (PNP) government, Fortis purchased the Grand Turk power company, Turks and Caicos Utilities from an American firm.

Following the initial Fortis buyout in 2006, the Misick government, which then included current premier Dr Rufus Ewing as director of medical services, proceeded to enter into a hugely expensive and controversial healthcare contract with another Canadian company, Interhealth Canada.

Interest in the Misick connection with Canada has also been revived by some so far unconfirmed but informed reports that he may be a person of interest so far as the Canadian authorities are concerned.

Speculation that the Canadians may have had a hand in Misick’s travel back to the TCI following his recent extradition from Brazil has led to questions as to whether this was designed to protect or pursue significant political and other figures in Canada.

In fact, Canadian interest in the TCI has been around since 1917, when then Canadian prime minister Robert Borden suggested that Canada annex the islands. In 2004, Nova Scotia’s three parties voted unanimously to let the TCI join their province if they ever became part of Canada.

Similar discussions were held by former premier Misick.

As recently as last year, Canadian MP Peter Goldring wanted to revive the proposal for the TCI to join Canada, following the return of elected self-government in the territory in November 2012.

Goldring has been a consistent advocate of increased cultural and economic ties between the TCI and Canada for more than ten years but the idea was dropped when Britain imposed direct rule in 2009, following a commission of inquiry that uncovered widespread and systemic government corruption in the territory.

Goldring, who has visited the islands several times, said they would fit in nicely with the rest of Canada.

But Canada stands to gain more than simply a vacation destination from such a union, he said: "From my perspective, certainly it goes far behind sun and sand. South Caicos Island, for example, is on a deep water channel. It could be readily developed into a deep-water port, which would give Canada tremendous advantage for trans-shipment throughout the entire region."

He added the islands would be a strategic location from which to increase engagement with Haiti and Cuba.

The Peak Oil Crisis: A $4 Trillion Hole

Last week reporters at the Wall Street Journal sat down and did some arithmetic.

Tom Whipple

They looked at how much oil was selling for in the spring of 2014 (over $100 a barrel); looked at what it is selling for today (under $50); and concluded that if prices stay low for the next three years, the global oil industry and the countries it finances will be out $4.4 trillion in revenues. As these oil companies, nationalized and publically traded, will be producing roughly the same amount of oil in the next few years, the $4 trillion will have to come mostly out of profits or capital expenditures.

This is where the problem for the future of the world’s oil supply comes in. The big oil companies, especially those that export much of their production, have been doing quite well in recent years. National oil companies have earned vast profits for their political masters. Publically traded ones have developed a tradition of paying out good dividends which they are loathe to cut.

This leaves mostly capital expenditures on exploring for and producing more oil in coming years to take a dive as part of the $4 trillion revenue hit. Even if oil prices of $50 a barrel or less do not continue for the next three years, this still works out to a revenue drop of $1.5 trillion a year or about three times the planned capital expenditures of some 500 oil companies recently surveyed.

The International Energy Agency just came out with a new forecast saying that while current oil prices have the demand for oil products increasing rapidly, there is still so much over-production that the oil glut is expected to last for another year or more before supply/demand comes back into balance. The return of Iran to unfettered production would not help matters.

In looking at the next five years there are several trends or major issues that are likely to impact the supply and demand for oil. First is the recent price collapse that no longer makes it profitable to start projects to produce new oil, most of which now comes from deepwater, tar sands, or shale oil fields and is far more expensive to produce than "conventional" oil. As a result, investment in new oil production projects has dropped substantially in the last year and is likely to fall further.

On the demand side of the equation China is the biggest unknown. For the last 30 years the Chinese have enjoyed unprecedented economic growth, but recently the "world’s factory" has not been doing as well. Its government has been thrashing around wildly trying to stimulate growth and fend off a collapse in its stock market. Some believe China is a huge economic bubble that is about to collapse taking much of the world with it, and obviously reducing its ever-increasing demand for more oil.

The other 800-pound gorilla looming out there is climate change. Except for the drought in California and the storm that flooded New York a few years back, much of America and China for that matter has not been hurt badly enough by anomalous weather to reach an agreement that stopping climate change is the number one priority of all of us. Reports of "feels like" 159°F coming out the Middle East this summer have little impact on those convinced that climate change is a hoax. Should the effects of climate change worsen in the near future to the point that "do something before life on earth becomes impossible" becomes the majority perception of the issue, consumption of fossil fuels could be severely restricted. Although not widely appreciated, there do seem to be viable alternatives to fossil fuels waiting to be exploited.

The violence in the Middle East has grown worse in recent years. Although oil production in some areas has been restricted by geopolitics and violence, most of the oil continues to be produced. It is useless to talk about the next five years in the Middle East; however, we should keep in mind that there are at least a half dozen confrontations going on in the region that could morph into situations where oil production becomes more restricted.

When we net this all together, what do we have? Conventional wisdom currently says that oil prices are likely to be closer to $50 a barrel than to $100 for the next year or more. Capital spending on new production to offset declining production from existing oilfields is likely to drop still further leaving us in the situation where depletion may exceed the oil coming from new wells or fields. This is the argument that those who believe that we are at or near the all-time peak of world oil production about now are using.

The International Energy Agency says that the demand for the cheaper oil is rising rapidly, that production of shale oil currently is falling and the rest of world’s production is relatively static so we should be seeing oil prices rising again by 2017. This is where the turning point in the history of oil production could occur. In recent history rising prices have led oil producers to increase drilling for new oil production again. However the next time around, as mentioned above, there are new factors that may come into play. Will China be increasing its demand for oil in another two years? Will the Middle East still be exporting as much oil, and producing oil given the turmoil and the need to increase air conditioning? Will the world have decided the time has come to clamp down seriously on carbon emissions?

If global oil production does reach some kind of a peak this year and is lower in 2016, can it recover to reach new highs in the years following? Anything from inadequate investment stemming from persistently low oil prices to a major conflict in the Middle East could keep production from rebounding to new all-time highs. We are living in interesting times and just could see peak oil before we realize it. More

Solar power could be world's top electricity source by 2050

Solar energy could be the top source of electricity by 2050, aided by plummeting costs of the equipment to generate it, a report from the International Energy Agency (IEA), the West’s energy watchdog, said on Monday.

IEA Reports said solar photovoltaic (PV) systems could generate up to 16% of the world’s electricity by 2050, while solar thermal electricity (STE) - from “concentrating” solar power plants - could provide a further 11%.

“The rapid cost decrease of photovoltaic modules and systems in the last few years has opened new perspectives for using solar energy as a major source of electricity in the coming years and decades,” said IEA Executive Director Maria van der Hoeven.

Solar photovoltaic (PV) panels constitute the fastest-growing renewable energy technology in the world since 2000, although solar is still less than 1% of energy capacity worldwide.

The IEA said PV expansion would be led by China, followed by the United States, while STE could also grow in the United States along with Africa, India and the Middle East. More

Why Morgan Stanley Is Betting That Tesla Will Kill Your Power Company

There’s a reason that power companies are attacking rooftop solar across the nation: They see those silicon panels as nothing short of an existential threat.

As the cost of solar continues to fall, and more people opt for the distributed power offered by solar, there will be less demand for big power plants and the utilities that operate them. And one major investment giant has now released three separate reports arguing that Tesla Motors is going to help kill power companies off altogether.

Earlier this year, Morgan Stanley stirred up controversy when it released a report that suggested that the increasing viability of consumer solar, paired with better battery technology—that allows people to generate, and store, their own electricity—could send the decades-old utility industry into a death spiral. Then, the firm released another one, further emphasizing the points made in the first. Now, it’s tripling down on the idea with yet another report that spells out how Tesla and home solar will “disrupt” utilities.

“There may be a ‘tipping point’ that causes customers to seek an off-grid approach,” the March report argued. ”The more customers move to solar, the [more the] remaining utility customers’ bills will rise, creating even further ‘headroom’ for Tesla’s off-grid approach.”

Yes, Tesla Motors, everyone’s favorite electric car company. And that’s where the controversy comes in. Morgan Stanley breathlessly pegged Tesla as “the most important auto company in the world” in part because its electric car business was pushing it to develop better energy storage technology, and then mass manufacture said batteries. That’s exactly what Tesla CEO Elon Musk and company will be doing at its forthcoming Gigafactory, which it is building in the Southwest with Panasonic.

With the new manufacturing facility, Morgan Stanley reasons, Tesla stands to double its business (adding another $2 billion in revenue) by selling the lithium ion batteries it typically ships under the hood of a Model S to homeowners with solar panels, too. If consumers can store energy the panels generate during the day for use at night, it would ostensibly render the need for utilities to pipe in faraway power—and their electric bills—obsolete.

Energy storage, when combined with solar power, could disrupt utilities in the US and Europe to the extent customers move to an off-grid approach

Musk is also the chairman of Solar City, a company that leases rooftop solar setups to homeowners, and one that would benefit from the battery tech. Now, the shadiness here is that Morgan Stanley released the report trumpeting Tesla’s crossover energy storage potential—causing Tesla’s stock to rise—right before it underwrote a fundraising round for… Tesla.

So the whole thing is very incestuous, and it does render some of the projections a little suspect, but the bottom line here is that private solar and battery companies are viable enough that they’ve attracted the backing of one of the world’s biggest financial services companies—over the multi-trillion dollar utility industry.

“Energy storage, when combined with solar power, could disrupt utilities in the US and Europe to the extent customers move to an off-grid approach,” Morgan Stanley writes in its third report this year emphasizing the prospect. ”We believe Tesla’s energy storage product will be economically viable in parts of the US and Europe, and at a fraction of the cost of current storage alternatives.”

In other words, Morgan Stanley has Tesla’s back, big time. It’s betting that Musk is going to make the best solar energy batteries money can buy.

Ironically enough, however, even staunch clean energy advocates are wary about Morgan Stanley’s finding that utilities are going the way of the buffalo. “Barring extraordinary circumstances, the economic case for grid defection is still very weak for US consumers,” Stephen Lacey, the senior editor of Greentech Media, wrote of the Morgan Stanley report. ”The electricity system offers valuable backup in case a customer over- or under-invests in an on-site system.”

It’s more likely, then, that people will still buy home solar—by the tens of millions, Greentech suggests—but not unplug from the grid entirely. Utilities will be diminished, but not broken. This process is underway in Europe already, where countries like Germany have powerful incentives for consumers to switch to solar.

Last year, the Economist called the sharp decline of European utilities “startling,” noting that together, they lost half their value—$600 billion—in just five years. Here in the states, utilities and conservative politicians are fighting solar tax credits to prevent the same thing from happening. For the most part, the utilities are losing.

All of this is, ideally, what needs to happen. Climate change is accelerating, and we need to transition away from those massive, fossil fuel-slurping power plants. Distributed solar is an increasingly powerful force behind that weaning process.

And even if some of Morgan Stanley’s calculations are shaky, the trends that Tesla is helping to amplify are anything but—clean, personalized (or community-wide) power will play a major role in shaping our energy future.

The fact that a greed-driven titan of finance like Morgan Stanley recognizes as much, and is willing to triple down on its bets on battery storage and distributed power, is a promising sign that the energy revolution is underway. More

Inside the Huge Solar Farm That Powers Apple's iCloud

Inside the Huge Solar Farm That Powers Apple's iCloud

This story was originally published by the Guardian and is reproduced here as part of the Climate Desk collaboration. The article was reported by the Guardian's Suzanne Goldenberg, and the video was produced by Climate Desk's James West.

The skies are threatening to pour on the Apple solar farm but as the woman in charge of the company's environmental initiatives points out: The panels are still putting out some power. Apple is still greening its act.

The company, which once drew fire from campaigners for working conditions in China and heavy reliance on fossil fuels, is now leading other technology companies in controlling its own power supply and expanding its use of renewable energy.

After converting all of its data centers to clean energy, the Guardian understands Apple is poised to use solar power to manufacture sapphire screens for the iPhone 6, at a factory in Arizona.

And in a departure for its reputation for secretiveness, Apple is going out of its way to get credit for its green efforts.

"We know that our customers expect us to do the right thing about these issues," Lisa Jackson, the vice-president of environmental initiatives told the Guardian.

This week the company invited journalists on a rare tour of its data center in North Carolina to showcase its efforts.

Until a year ago, the telegenic Jackson was the front woman for Barack Obama's environmental ambitions as the administrator of the Environmental Protection Agency.

Now she is leading the effort to shrink Apple's carbon footprint—and make sure customers realize the company is doing its bit to decarbonize its products and the internet.

Data centers require huge loads of electricity to maintain climatic conditions and run the servers carrying out billions of electronic transactions every day.

With Apple's solar farm, customers could now be confident that downloading an app or video-chatting a friend would not increase carbon pollution, Jackson said.

"If you are using your iPhone, iPad, Siri or downloading a song, you don't have to worry if you are contributing to the climate change problem in the world because Apple has already thought about that for you. We've taken care of that. We're using clean energy," she said.

The company is also moving to install solar and geothermal power at a plant in Mesa, Arizona, that has been manufacturing sapphire glass. Apple would not directly comment on the Arizona factory but the state's governor, Jan Brewer, has publicly praised the company's decision to relocate there and to use solar and geothermal in manufacturing.

"We are aware that almost 70 percent of our carbon footprint is in our supply chain," Jackson said. "We are actively working on the facilities that we have here in the United States."

The initiatives mark a turnaround for Apple, which was criticized in the past for working conditions and the use of toxic chemicals at its factories in China and for its heavy reliance on carbon intensive sources such as coal to power the cloud.

Greenpeace now says the company is out ahead of competitors like Google and Facebook, which also operate data centers in North Carolina.

"They are the gold standard in the state right now," said David Pomerantz, a senior Greenpeace campaigner. "There are a lot of data centers in North Carolina and definitely none has moved as aggressively as Apple has to power with renewable energy," he said.

The 55,000 solar panels tracking the course of the sun from a 400,000 square meter field across the road from Apple's data center in Maiden were not in the picture seven years ago when Duke Energy and local government officials sought to entice Apple to open up a data center in North Carolina.

Duke Energy, which has a near monopoly over power supply in the Carolinas, set out to lure big companies like Apple, Facebook and Google to the state with offers of cheap and reliable power for the data centers that are the hub of internet.

Data centers, with their densely packed rows of servers and requirements for climatically controlled conditions, are notorious energy hogs. Some use as much power as a small city. In Apple's case, the North Carolina data center requires as much power as about 14,000 homes—about three times as much as the nearby town of Maiden.

Charging up a smart phone or tablet takes relatively little electricity, but watching an hour of streamed or internet video every week for a year uses up about as much power as running two refrigerators for a year because of the energy powering data centers elsewhere.

That made data centers a perfect fit for Duke, said Tom Williams, the company's director of external relations. With the decline in textile and furniture factories that had been a mainstay in the state, the company had a glut of electricity.

"What the data centers wanted from Duke was low cost and reliable power. Those two things—cost and reliability—are fundamental to their operations," he told the Guardian. "What we like about these data centers is that it's an additional load on our system."

In the early days, Apple bought renewable energy credits to cover the center's electricity use. In 2012, the company built its first solar farm across the road from the data center.

Apple built a second solar farm, and announced plans this month for a third, all roughly about the same size, to keep up with the growing use of data. It also operates fuel cells, running on biogas pumped in from a landfill. All of the power generated on-site is fed into the electricity grid.

"On any given day 100 percent of the data center's needs are being generated by the solar power and the fuel cells," Jackson said.

The company has been less successful in its efforts to get other companies to switch to solar power. Duke, in cooperation with Apple, launched an initiative last year to encourage other big electricity users to go solar but so far there have been no takers.

Renewable energy accounts for barely 2 percent of the power generated in North Carolina, and Duke does not see the share growing significantly by 2020. More
