Why California’s New Home Solar Requirement Includes Batteries and Not Zero Net Energy

California’s recently adopted building standards require solar to be a part of all new residential construction. As the first state to enact such a standard, it’s been lauded as a historic and game-changing event for solar power in the U.S. But some have argued that the new standards don’t go far enough.

Battery Storage: After 100 Years, The Market Finally Arrives

After a hundred years of technology improvement, an old enabling technology — battery storage — has emerged anew.

Recharging the Clean Energy Transition with Battery Storage

It’s rare to have an opportunity to shape an energy technology market as it emerges. Today, battery storage is that energy technology.

FERC 841 Opens Markets to Energy Storage

Last month’s FERC order 841 was hailed by some as a watershed moment in energy storage history, but the devil’s in the implementation.

California Utilities Propose Storage for Energy Resilience and Equity, But More Needs to be Done

Three of California’s largest utilities recently proposed more than 100 megawatts of utility-owned energy storage to support resiliency in critical public facilities and $6 million in incentives for customer-owned storage at multifamily affordable housing properties.

Federal Energy Funds for Puerto Rico, A Small Down Payment

Just this past week, Puerto Rico suffered another setback in its effort to restore power to the island. One of its 400 megawatt power plants caught fire, plunging people back into the darkness.

The Launch of a U.S. Offshore Wind Industry

Contributing to the growing list of major milestones for the U.S. offshore wind sector, this week the Governors from both New York and New Jersey announced commitments to launch the nation’s largest offshore wind solicitations. These commitments confirm the strong business case for offshore wind.

It’s Time to Recognize the Value of Resilience

Extreme weather and related power outages come with a price tag, but these costs are not typically accounted for when considering the potential benefits of a resilient power system. The result is that fewer solar+storage systems pencil-out to make economic sense than would be the case if the power resilience they provide was accurately valued.

Will 2018 Be Another Good Year for U.S. Offshore Wind?

2017 was a banner year for offshore wind in the U.S. Boosted by the start of commercial operations at the Block Island Wind Farm in December 2016, the offshore wind sector gathered momentum and made significant progress over the year.

Powerless in Atlanta

Any investigation into the massive power outage at Atlanta’s international airport last month should not only look back to see what went wrong. Rather, it should look forward to how the airport could use new technologies like solar and battery storage to prevent such disasters from happening again.
