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.

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

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

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.

Public Wave Energy Test Facility Begins Operation in Oregon

ScienceDaily (Aug. 21, 2012) — One of the first public wave energy testing systems in the United States began operation this week off the Oregon coast near Newport, and will allow private industry or academic researchers to test new technology that may help advance this promising form of sustainable energy.

The Ocean Sentinel is a $1.5 million device developed by the Northwest National Marine Renewable Energy Center, or NNMREC, at Oregon State University. It's a major step forward for the future of wave energy, and should do its first testing within days -- a "WetNZ" device developed by private industry.

The creation of this mobile wave energy test facility has been needed for years, experts say, and it will be used by many companies and academic researchers in the quest to develop wave energy technology, measure and understand the wave resource, and study the energy output and other important issues.

"The Ocean Sentinel will provide a standardized, accurate system to compare various wave energy technologies, including systems that may be better for one type of wave situation or another," said Sean Moran, ocean test facilities manager with NNMREC.

"We have to find out more about which technologies work best, in what conditions, and what environmental impacts there may be," Moran said. "We're not assuming anything. We're first trying to answer the question, 'Is this a good idea or not?' And if some technology doesn't work as well, we want to find that out quickly, and cheaply, and the Ocean Sentinel will help us do that."

Experts say that, unlike some alternative energy forms such as wind energy, it's probable that no one technology will dominate the wave energy field. Some systems may work better in low wave settings, others with a more powerful resource. The Ocean Sentinel will be able to measure wave amplitude, device energy output, ocean currents, wind speeds, extremes of wave height and other data.

This initiative was made possible by support from the U.S. Department of Energy, the Oregon Department of Energy, and the Oregon Wave Energy Trust. More
