Quantifying uncertainty to produce more useful solar generation forecasts
Renewable energy firm PowerUQ advocates for the use of Uncertainty Quantification (UQ) in solar project analytics to combat the widespread issue of performance shortfalls. By incorporating a wider range of variables and providing probability scenarios like P50 and P90, UQ aims to make solar generation forecasts more useful and accurate over a project’s long lifespan.
Fullmark Energy closes $46 million tax credit transfer for 120 MW / 290 MWh storage portfolio
Fullmark Energy completed the $46 million Investment Tax Credit transfer for its operational 125 MW / 290 MWh Redwood Projects energy storage portfolio in California.
Over 13 GW, or half of planned Texas solar and storage, at risk to fail to come online next year
The Solar Energy Industries Association (SEIA) has released an analysis indicating that new federal policies targeting renewable energy are placing a significant majority of planned solar and battery storage capacity in Texas at severe risk.
Utility-scale solar project delays ease as market matures, says EIA
About 20% of planned capacity additions reported delays in Q3 2025, down from the 25% of projects reporting delays in Q3 2024.
Grid operator PJM reports progress on interconnecting new generation as capacity costs surge
PJM said it agrees with many of the recommendations for speeding transmission interconnection made by the nonprofit group RMI, and reported it has completed 600 interconnection studies in less than 22 months under its current interconnection study process. Even so, a GridLab report says PJM would have substantially lower capacity costs next year if a modest portion of renewable and storage projects in PJM’s queue had been set to reach operation by then.
Universities are turning solar furniture into campus infrastructure
As universities expand outdoor learning, off-grid solar furniture is emerging as a new class of campus infrastructure.
Sodium-ion battery storage for ultra-low temperatures
U.S. researchers have developed a sodium-ion pouch cell that operates reliably at temperatures as low as –100 C. The battery was tested with simulated and real renewable energy sources, including wind and solar, and maintained stable performance in both laboratory and field conditions.
Quino Energy expects Indian flow battery deal to spur U.S. deployments
Energy storage in urban areas make strong use case for non-flammable flow batteries.
Over 50 House Republicans urge Trump administration to block Chinese solar inverter imports
More than 50 House Republicans are urging the Trump administration to prohibit the import of solar and battery energy storage inverters manufactured by companies from “foreign entities of concern” (FEOCs).
