Electric utilities; certificate of operation for high-load facilities. Prohibits any person from operating a high-load facility, defined in the bill as a facility whose electricity demand exceeds 25 megawatts that was not operating before July 1, 2026, without first having obtained a certificate of operation from the State Corporation Commission. The bill includes factors for the Commission to consider in reviewing a petition to operate a high-load facility. The bill establishes a presumption that a high-load facility shall be considered to have met certain requirements if the high-load facility has secured sufficient contracts for energy storage resources or zero-carbon electric generating resources or that the high-load facility has a plan to implement sufficient demand reduction measures. The bill also requires the Commission to consider certain factors in a review of a petition for a certificate to operate a high-load facility, including whether there is sufficient energy, capacity, and grid infrastructure to support the operation of the high-load facility and whether the operation of the high-load facility would create an unreasonable cross-subsidy across customers served by the incumbent electric utility.
