Batteries are stabilizing the Texas power grid
A study by North American Electric Reliability Corporation found that ultra-fast response times of batteries help to stabilize the grid better than slower thermal sources.
Abandoned coal mines can host over 10% of global solar capacity
A survey of mines closed since 2020 and those planned to close by 2030 present an opportunity for installing nearly 300 GW solar on already-developed lands, finds a report from Global Energy Monitor.
Interconnection shake-out: 160 GW of solar advances as 12% of projects bow out
About one-sixth of queued solar capacity now holds signed interconnection agreements, signaling real progress even as developers pull more than 130 GW of projects amid tightening interconnection rules.
Connector failure accounts for loss of 58% of revenue in commercial solar portfolios
A report from HelioVolta finds connector issues in four out of five solar projects in the United States and details what can be done from procurement to field inspections to minimize risk.
Despite low gas prices, solar, wind remain cheapest sources of power in U.S.
Renewables remain cost-competitive in the United States despite rising natural gas competitiveness, according to Lazard’s 2025 “Levelized Cost of Energy+” report, which estimates combined cycle gas at $0.048/kWh to $0.107/kWh, solar at $0.038/kWh to $0.212/kWh, and nuclear at $0.141/kWh to $0.220/kWh.
Perovskite tandem provider Swift Solar to explore telecom tower integration
The MIT/Stanford spinoff announced a collaboration with American Tower Corporation to evaluate high energy density solar panels for telecom towers.
Tracking the top states for community solar
The Institute for Local Self-Reliance releases its quarterly community solar tracker, which updates capacity in states with formal programs that allow non-utility ownership.
Flexible transmission allocation would allow Western solar projects to proceed
Enabling renewable projects in the Pacific Northwest to obtain flexible transmission rights could help states reduce electricity costs and meet renewables targets, suggests a report. The approach could also have utility in most of the West.
CSP-driven multigeneration system combines hydrogen generation with compressed air, pumped hydro storage
Researchers have designed a novel multigeneration energy system that provides five outputs, namely electricity, hydrogen, cooling, heating, and hot water. The system is mainly powered by a solar heliostat system and incorporates compressed air and pumped hydro storage technologies for storing surplus power.
Grid operator SPP partners with Hitachi to speed interconnection studies
The partnership aims to reduce interconnection study times by 80%, to address SPP’s portion of a national bottleneck of 2,500 GW of solar, wind and storage projects awaiting interconnection.
