A bill to ease the impacts from the pending closure of California’s last nuclear power plant received final approval by the state Legislature with an overwhelming Assembly vote Monday night — a decision that likely will increase monthly utility bills for PG&E customers.

San Francisco-based PG&E intends to phase out the reactors of its Diablo Canyon nuclear power plant in San Luis Obispo County when their operating licenses with the U.S. Nuclear Regulatory Commission expire in November 2024 and August 2025.

“If approved, the programs in the bill would result in a small, short-term increase of about 0.2 percent to the average customer’s monthly bill,” Blair Jones, a PG&E spokesperson, said Monday. “This increase would be removed from rates in 2026.”

The legislation that the Assembly approved Monday in a 67-1 vote would order the state Public Utilities Commission to fully fund worker retention and community transition provisions that were contained in the historic agreement to guide the nuclear plant’s shutdown.

“The Diablo Canyon joint proposal represented a significant milestone in the planning to meet California’s bold clean-energy vision,” PG&E’s Jones said Monday. “It’s important to ensure that the remaining goals of this transition strategy are enacted.”

The bill, now headed to Gov. Jerry Brown for his signature, directs the PUC to approve an $85 million payment to San Luis Obispo County, some cities in the area and a local school district to ease the loss of economic benefits that the plant contributes. This provision was criticized by some consumer groups because it means PG&E customers would be obliged to make up for the loss of some property taxes when the plant closes.

The bill also directs the PUC to authorize complete funding of a $350 million employee retention program.

If Gov. Brown signs the bill, the combined effect of the legislation and of prior action by the state Public Utilities Commission related to the plant’s shutdown potentially could produce a 1.2 percent increase in PG&E customers’ monthly bills.

When PG&E announced its original proposal in June 2016 for the shutdown of Diablo Canyon, Geisha Williams, now the company’s chief executive officer, and at the time president of electric at PG&E’s utility subsidiary, stated, “There is no need for a cost increase from our customers.”

However, a few months later, in October 2016, PG&E circulated bill inserts that revealed PUC approval of the original proposal to shutter the plant actually would result in a 1.6 percent increase in monthly electricity bills on a “short-term” basis lasting through 2025.

Ultimately, the PUC approved a plan in May 2017 that stripped a number of provisions out of the original agreement regarding the Diablo Canyon power plant.

The Utility Reform Network, a consumer group, hailed the PUC decision because the action would ease the financial impact on ratepayers to cover the nuclear plant’s shutdown. Estimates at the time pointed to a 1 percent increase in monthly bills due to the PUC’s actions — less than the increase that the PG&E bill inserts had previously suggested.

The PUC’s decision dismayed PG&E, which vowed to revisit the lost provisions in 2018 with the state agency. State lawmakers also floated legislation to restore provisions the PUC had removed.

The resulting bill approved by the Assembly on Monday had broad support, according to a blog post Monday by Peter Miller, western energy director of the Natural Resources Defense Council.

“SB 1090 has received strong bipartisan support since it was introduced, along with the enthusiastic support of a wide range of organizations and businesses, including the workers who operate the plant and the communities that have hosted it since it began operating near San Luis Obispo in 1984,” Miller wrote.
