Small-scale PV additions last year exceeded additions in 2021 by 1 GW, and additions in 2020 by 2 GW.

The U.S. Department of Energy said it may designate “National Interest Electric Transmission Corridors” based partly on the final results from its national transmission needs study.

A report requested by California’s legislature discusses both expected cost savings from expanding the state’s grid operator into a regional transmission organization, and a potential loss of state policy control.

An Energy Systems Integration Group report calls for improved approaches to crediting resources for their capacity contribution, starting with fair treatment for all resources.

The Smart Electric Power Alliance survey reports utilities’ progress on actions that can support the deployment of solar, wind and storage.

Texas grid operator ERCOT advanced interconnection requests for 15 GW of solar projects last year, with three other grid operators advancing 9 GW. CAISO completed phase 1 studies for a large cluster of projects, while PJM and ISO-NE stayed mum on their progress.

With increasing adoption of electric vehicles and heat pumps, whose demand can be flexible, “marrying” that trend with the upward trend of variable renewable generation “could accelerate both,” said a paper from the Energy Systems Integration Group.

A $1 to $1.5 billion U.S. market opportunity awaits PV equipment manufacturers through 2030, said a McKinsey consultant, at a Washington D.C. event that brought together potential equipment buyers and sellers.

Some utilities are using models to project the adoption of distributed solar and storage, and counting distributed resources in their planning process. Others should do the same, says the nonprofit RMI.

Rapidly deploying 5.2 GW of planned solar and storage in Puerto Rico to reach 36% renewables, a possibility raised in a report by six national laboratories, would require an improvement in the Puerto Rico utility’s practices, which involve delays at several steps of the procurement process.
