Solar-plus-storage has a 99.8% capacity value in California
“The energy from solar can consistently charge a 4-hour storage device having the same installed capacity” prior to the hours of peak demand, says a new study. In Arizona and New Mexico the capacity value is 99%.
IREC, SEIA, ESA, EPRI team up to speed distributed storage interconnection
“Getting interconnection of storage right is absolutely fundamental to avoid potential barriers for rapidly rising energy storage deployments,” said Jason Burwen, of project partner Energy Storage Association.
Discriminatory rooftop solar charges may violate antitrust law
The U.S. Department of Justice has argued that in Arizona, a utility’s discriminatory charges for rooftop solar owners can be “unlawful.” The Center for Biological Diversity also supported the four rooftop solar owners whose lawsuit has progressed, arguing the legal significance of Arizona’s renewables goals.
How to replace 187 GW of coal with renewables, and save customers money
Several financing options could ease the replacement of uneconomic coal plants with renewables and storage, with some of the savings used to help coal workers transition to new jobs, says a report from climate advocates.
North Carolina pursues faster interconnection for utility-scale solar
Under Duke Energy’s current review process, interconnection queues grew to 14 GW in North and South Carolina last year. A new process should speed interconnection reviews, and enable projects located near each other to share the costs of transmission upgrades.
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.
