Sunrise brief: Annual U.S. clean energy investment grows 37%
Also on the rise: Plus Power raises $1.8 billion to advance construction of five energy storage facilities. Solar power purchase agreement prices rise 21% year over year. And more.
New opportunities for 4-hour-plus energy storage
Energy storage with more than four hours of duration could assume a key role in integrating renewable energy into the U.S. power grid on the back of a potential shift to net winter demand peaks, says the National Renewable Energy Laboratory (NREL).
Grid-forming inverters will enable a high-renewables grid
As renewable generation increases, so does the need for grid-forming inverters to provide the same functionality that rotating synchronous generators provide. The UNIFI Consortium is coordinating industry progress on the new inverter technology.

Large solar projects have no negative impact on property values, study says
A study commissioned by Conservative Texans for Energy Innovation, Advanced Power Alliance and the Solar Energy Industries Association looked at market trends near six utility-scale solar projects.
Sunrise brief: Utility-scale project updates for booming Texas solar market
Also on the rise: Toledo Solar and First Solar reach agreement in lawsuit. Massachusetts can save 4.6 million metric tons of carbon by changing solar development strategy. And more.
Virginia utility’s resource plan needs more solar and storage, says trade group
The trade group Advanced Energy United called on Virginia regulators to reject Dominion Energy’s proposed resource plan because it lowballed renewables and storage. The Sierra Club said 15 GW more solar and 5 GW more storage by 2038 would be optimal.
HVDC transmission serves mostly wind and hydro power, not solar
A report from The Brattle Group and DNV recommends clearing barriers in the U.S. to high-voltage direct current (HVDC) transmission. HVDC transmission projects show many cost-saving use cases, but so far, transmitting solar power is rarely among them.
Hydrogen stations could avoid unplanned shut-downs with predictive models, research finds
The NREL study focuses on a specific model that uses data to reduce the frequency of unscheduled maintenance, and increase the frequency of preventive maintenance.
