This bill prohibits an entity providing generation service to data centers in the State from providing an amount of electricity that is more than 25% of the amount of electricity sold to all of the entity's customers in the State in a calendar year. The prohibition does not apply to a generation service provider that is providing generation service behind the meter to a data center adjacent to the electricity generating facility. The bill requires generation service providers to file quarterly reports with the Public Utilities Commission, including information about data centers that are receiving service from the generation service provider. The Public Utilities Commission may adopt routine technical rules to implement the requirements of this legislation.
