Scheduled home charging of EVs reduces the cost for hosting more electric vehicles on a utility’s distribution circuit, according to a national laboratory analysis.
A clean energy plan for TVA sponsored by the Center for Biological Diversity and GridLab could save customers about $200 billion through 2050. It calls for almost four times more solar by 2035 than the maximum amount TVA was considering last year.
The grid operator’s projected 5% “completion rate” for projects in its interconnection queue was questioned by executives at the renewables trade group ACORE and the consultancy GridLab.
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.
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.
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.
