On July 23, 2020, the Massachusetts Department of Energy Resources (“DOER”) filed final regulations implementing a “Clean Peak Energy Standard,” which formally went into effect on August 7, 2020.  The final regulations are the latest step towards making reality out of an idea enacted through the 2018 Act to Advance Clean Energy and make Massachusetts the first state to adopt such a program.… More

On July 10, 2020, the D.C. Circuit upheld FERC Order 841, the landmark order requiring wholesale markets to allow participation by energy storage resources.  Challengers had contended that by prohibiting states from barring energy storage resources on the distribution system from participating in wholesale markets, FERC had exceeded its jurisdiction and infringed on state authority.

The D.C. Circuit rejected those claims. … More

Energy storage will play a key role in achieving New York State’s bold climate vision, set in motion in June 2019 with the passage of The Climate Leadership and Clean Energy Protection Act, the nation-leading law which calls for economy-wide emissions reductions to reach net-zero by 2050,100% clean electricity by 2040, and 70% renewable electricity by 2030. The Act also codifies an existing Cuomo Administration commitment to deploy 3,000 MW of energy storage by 2030.… More
