Groups challenge TVA’s draft resource plan that commits to only 3 GW solar
Critics say the federally owned utility TVA, now at 2% solar, plans more gas units, no solar-plus-storage and no long-term storage, in a resource plan that lacks transparency, with no public hearing planned. They asked TVA’s board to ensure improvements.
How to quickly add gigawatts of batteries to the PJM grid
Mid-Atlantic grid operator PJM has a ready opportunity to enable substantially more battery capacity and prevent a near-term resource adequacy shortfall, says a trade group report.
Reaching 45% solar generation would save Southeast utilities $20 billion/year
Annual savings of $20 billion are possible across six Southeastern states by reaching 45% solar generation by 2035, according to a national laboratory study.
Firebrick thermal energy storage could reach 170 GW in the U.S. by 2050
Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a study out of Stanford University.
Solar tussles in Puerto Rico
Lawsuits, an imminent threat to net metering, and questions over commitments to the energy transition in some quarters pose real challenges for solar in Puerto Rico. Despite this, the US territory is still a high flyer in the region when it comes to distributed generation, while larger-scale solar and storage are on course to benefit from a US Department of Energy (DoE) loan guarantee.
Completing Western transmission lines would enable 73 GW of renewables and storage
The benefits of completing 12 Western transmission projects, as identified in a federal study, will form the region’s new baseline for a forthcoming National Transmission Planning Study.
Firebrick thermal storage for industry could receive $75 million in federal funds
Two projects that would store heat in firebricks for industrial use may receive federal funding, in part because the projects are deemed highly replicable.
Software will complete first-stage interconnection studies in one day, firm says
As a grid operator works to automate its phase 1 study process for interconnecting solar, storage and other generating projects, the firm developing the automation software says the study process will take just one day.
DOE calls for faster interconnection of distributed solar and storage at lower cost
Solar and storage systems smaller than 50 kW would receive an interconnection agreement instantly when requesting one, under 2030 targets in a draft Department of Energy roadmap.
Flexible interconnection at far lower cost and nearly twice the speed
Substantial cost and time savings are possible with flexible “connect and manage” interconnection of utility-scale solar and solar-plus-storage projects, two studies have found.
