This bill mandates that data centers providing computing resources for developing generative artificial intelligence models must estimate and report the total energy used in the development process. Developers must inform data centers of their intent to develop a covered model and request energy usage data from all involved data centers before using the model commercially. Additionally, the bill requires the State Energy Resources Conservation and Development Commission (Energy Commission) to require data centers to report energy consumption data annually, adopt energy efficiency performance standards, and include energy consumption trends in its biennial integrated energy policy reports. The Public Utilities Commission (PUC) is tasked with determining whether costs related to the construction or alteration of data centers are just and reasonable, ensuring costs are not unfairly shifted to unrelated ratepayers.
