The reporting, which will be required at least annually, will include data on the average, median, and standard deviation times for interconnection requests that exceed target maximum timelines. The bill also requires the CPUC to ensure that utilities “have sufficient and timely recovery of costs,” and allows for the commission to utilize a balancing mechanism for energization costs that exceed authorized rates.

“I am signing this bill because many of its provisions address this acute and critical issue with accountability metrics and a new, one-time revenue stream, with sensible customer protections,” Newsom wrote.

Advanced Energy United said interconnection delays are “a major obstacle” to customer adoption of clean energy technologies. SB 410 “helps break through the logjam,” said Emilie Olson, a senior principal who manages Advanced Energy United’s legislative engagements in California and Colorado.

“The bill enables faster interconnection timelines and increased transparency for utilities so they can make evaluations more quickly and speed up wired connections from homes and businesses to the grid,” Olson said after the bill passed the state’s legislature in September.

SB 410 was among a slate of clean energy bills Newsom signed this legislative session. Among others, AB 1373 creates a central procurement process for California to acquire clean energy, SB 48 aims to help improve efficiency in large commercial buildings, and SB 49 allows highway rights-of-way to be utilized for solar, storage and transmission. AB 3, the Offshore Wind and Jobs Act, aims to speed offshore renewable development by upgrading California’s ports.
