NREL study backs hydrogen for long-duration storage

Pumped hydro and compressed air energy storage will soon be cost-effective for day-long storage, while hydrogen for long-duration storage will be cost-effective by 2050 or sooner, the national lab’s study projected.

Real-time pricing that integrates more solar power is proven to work in California

Industry participants noted the significance of a real-time pricing project on a single distribution circuit in California. State officials are evaluating real-time pricing as a means to help integrate more solar and wind power on the grid.

SEIA finds rooftop solar is worth 24¢/kWh in Michigan

The value of rooftop solar is well above the net metering compensation paid to customers with rooftop solar, the solar association found.

Southeast states to add nearly 15 GW of solar by 2023

South Carolina is set to surpass North Carolina in solar watts per customer. Georgia and Florida will exceed the Southeast average, while utilities in Tennessee, Alabama and Mississippi will continue to lag. Overall the states will reach 5% solar generation by 2023.

Advocates seek solar on all new houses in ten states

“The most efficient time to install solar panels is when the builders are on the roof in the first place,” said Bronte Payne with Environment America.

Solar opportunities ‘ignored’ across 100 million acres in the Southwest

The Bureau of Land Management “has ignored most possibilities” for utility-scale solar “on its vast land holdings across the solar-rich Southwest,” says a paper. Renewable energy development accounts for less than 1% of economic activity on BLM lands, while oil and gas account for 70%, according to BLM data.

Solar hosting capacity maps must be accurate to be useful

Solar hosting capacity maps, now required in seven states, show where solar can be added on a distribution circuit without incurring any grid expense—but only if those maps are accurate. California’s experience, says a policy paper, shows that best practice guidelines for validating maps are needed to aid state regulators.

SEIA calls on FERC to dismiss the petition to end net metering

The Solar Energy Industries Association makes the case for the Federal Energy Regulatory Commission to dismiss the petition, solely on legal grounds. A filing by Solar United Neighbors, Vote Solar and other groups makes a legal case and also rebuts the petition’s claims about net metering.

90% clean power by 2035 is ‘challenging but feasible’

“90% by 2035 is the sweet spot” for a pathway that uses existing technology, allows “judicious use” of existing generation assets, and “achieves near-complete decarbonization in a realistic timeframe,” said study co-author Nikit Abhyankar of UC Berkeley. The resulting lower wholesale cost of electricity by 2035 “was a surprise for us.”

First Solar backs carbon pricing for wholesale electricity

First Solar has backed carbon pricing in comments submitted to the Federal Energy Regulatory Commission. The firm also co-founded a global policy institute that supports carbon pricing as a “cost-effective, equitable and politically viable climate solution.”
