PG&E Excess Supply Pilot
What is the XSP?
PG&E’s Excess Supply Pilot (XSP) investigates the ability of residential and commercial customers to help in times of excess supply to increase their energy usage when it is beneficial to the grid. As Pilot administrator, Olivine manages all aspects of the XSP to ease the implementation for participants.
Who Can Participate?
Subject to an enrollment cap, the XSP is open to aggregators within the PG&E service territory who can meet Pilot requirements.
What are the Pilot Participation Requirements?
As part of the requirements of the XSP, participants must:
- Be capable of achieving a minimum increase of 30 kW across 2 hours
- Be composed of one or more customer locations all within the same Sub Location Aggregation Point (Sub-LAP)
- All customers must be inactive on any other demand response program (including PDP and SmartRate) for the duration of the pilot (with the exception of SSP).
- Make monthly capacity nominations at the resource level
- Execute the appropriate participation agreements with Olivine
- Be subject to ongoing eligibility checks by PG&E
• The basis for capacity and payments in the XSP is the CAISO “10-in-10” baseline with the increase in demand compared against that baseline.
• Offsets to demand charge increases are available with certain limitations
• All payments will be made to the Participant by Olivine
In March 2017, PG&E and Olivine presented a public update to the CPUC Energy Division. The presentation is available here: Pilots Update for ED.
