Regional Western electricity market closer to reality following California vote

Bullet Utility Dive – September 15

California lawmakers on Saturday, September 13, approved Assembly Bill 825, a bill paving the way for a new, independent organization to oversee the existing Western Energy Imbalance Market and the pending Extended Day-Ahead Market (EDAM), marking an important step toward the regionalization of energy markets among Western states. California Energy Commission analysis concluded that joining EDAM could save Californians more than $1 billion a year and reduce greenhouse gas emissions by 58% in the state. The bill was part of a package of energy proposals that passed at the last minute and now heads to Gov. Gavin Newsom, who is expected to sign the bills. The package also included measures related to the state’s wildfire fund, virtual power plants, and reauthorizing the state’s cap and trade program for greenhouse gas emissions.

U.S. adds 17.9 GW solar PV in first half of 2025; SEIA predicts installation slowdown

Bullet PV-Tech – September 9

The U.S. has installed 17.92 GW of new solar capacity in the first half of the year, with quarter-on-quarter declines in capacity additions for the utility-scale and residential sectors, according to a new report from the Solar Energy Industries Association (SEIA) and Wood Mackenzie.

California’s first solar-covered canal is now fully online

Bullet Canary Media – September 10

A novel solar power project just went online in California’s Central Valley, with panels that span across canals in the vast agricultural region. The 1.6 MW installation, called Project Nexus, was fully completed late last month. The $20 million state-funded pilot has turned stretches of the Turlock Irrigation District’s canals into hubs of clean electricity generation in a remote area where hundreds of crops are grown. Proponents of this emerging approach say it can provide overlapping benefits.


Interior Department asks federal court to cancel permit for Maryland offshore wind farm

Bullet Reuters – September 12

The U.S. Department of Interior asked a federal judge to cancel the 2024 approval of a wind farm off the coast of Maryland, saying the former administration had underestimated threats it would cause to search and rescue operations and commercial fisheries, according to court documents filed on Friday. If approved by the court, the motion would invalidate a years-long federal process that permitted US Wind's Maryland Offshore Wind Project.

Bullet Solar Power World – September 16

Catalyze has completed four community solar projects in central and western New York, developed in partnership with CS Energy. The four projects total 27 MW.
