A lower-cost grid would reach 22% renewable generation in 2040, compared to the 5% currently planned by Southeastern utilities, says a study from Energy Innovation and Vibrant Clean Energy. Wholesale power trading through an independent system operator would also help reduce costs.
The utilities that buy power from TVA, and the 10 million people they serve, will be limited in accessing low-cost solar power unless a federal court invalidates what a lawsuit calls TVA’s “never-ending contracts.” Three citizens’ groups brought the lawsuit, claiming TVA violated a federal environmental law.
States like California whose laws say residential rooftop solar must be “intended primarily” for self-consumption could join Washington, D.C. in increasing their limit, says D.C. resident David Roodman. Generation in excess of consumption will be compensated at the wholesale rate in Washington.
If Congress wants to increase transmission of renewable power from high-resource areas to high-population areas, a report from the Federal Energy Regulatory Commission provides a roadmap. Co-locating transmission with highways is the greatest challenge.
The web-based app is designed to automate local government processing of solar permit applications, and has earned praise from local government officials in California who have tested it.
“Considering how off-track current plans are from where the science tells us we need to be to address the climate crisis, these plans are not in the best interest of Floridians,” says the Southern Alliance for Clean Energy. Stranded gas assets could raise customer bills, the group notes.
Proposed solar-plus-storage projects far surpass proposed gas units in the West and Midwest.
“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%.
“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.
