PG&E Excess Supply Pilot

What is the XSP?

The Pacific Gas and Electric Company (PG&E) Excess Supply Demand Response program (XSP) demonstrates capabilities of demand-side resources to consume or decrease load as a service to the grid to address intermittency due to oversupply of renewables generation as distributed generation accelerates. Designed to capture the full value of flexible resources to the grid it has been incorporated into initiatives across various consumer types including the California Energy Commission EPIC Total Charge Management project, PG&E’s Electric Vehicle Charge Network Load Management Plan, and the Pittsburg USD School Bus Renewables Integration Project.

PG&E and Olivine are recipients of a 2019 PLMA Pacesetter award! See our post for more information.
