Electrical corporations: interconnection: Public Utilities Commission: transmission development monitor

California will track and intervene when major power-grid and generator interconnection projects fall behind schedule.

Delays in transmission and grid-upgrade projects can hold up new power generation, storage, reliability work, and state energy goals. The law creates formal oversight and requires corrective action for delays utilities can reasonably control.

What the law does ​

  • Requires large electrical corporations and certain transmission owners to submit project schedules within one year of a qualifying transmission-plan approval, project-sponsor selection, or generator interconnection agreement.
  • Requires the California Public Utilities Commission to create a transmission development monitor by October 1, 2027, and standardized reporting templates by April 1, 2027.
  • Requires the monitor to track schedules, delays, project resources, permitting, procurement, and network-upgrade progress; publish annual reports; and flag material deficiencies.
  • Requires the commission to order remedial action within 90 days after receiving a report or deficiency notice for problems within an owner’s reasonable control.
  • Allows remedies including shifting staff or capital, accelerating procurement and preconstruction work, equipment sharing, generator-procured equipment, and generator or third-party construction options.
  • Lets the monitor refer delays outside an owner’s reasonable control to the Governor’s Office of Business and Economic Development for interagency coordination.

Who it affects ​

  • Large electrical corporations and transmission owners building commission-approved transmission or interconnection projects.
  • Generators, storage developers, and interconnection customers whose projects depend on grid upgrades.
  • The California Public Utilities Commission and its new transmission development monitor.

Context ​

A delay is not a material deficiency when it is attributable to factors beyond the utility or owner’s reasonable control, such as environmental review, permits, land access, safety changes, or supply-chain constraints.
