GRID-MAP Aggregator Resources
This page provides information for Aggregators, Customers interested in serving as their own Aggregator, and Customers and Trade Professionals who want to learn about and how to participate in GRID-MAP offered in SoCalGas service territory.
Qualifying Projects
As a meter-based pay-for-performance energy efficiency program, GRID-MAP offers nearly limitless opportunities for projects that can reliably demonstrate reductions in energy use as measured at the customer’s utility meter. Unlike traditional utility energy efficiency programs, the program measure savings based on “existing conditions” (the customer’s normalized usage in the 12 months prior to project installation). Typical energy efficiency projects include: HVAC, water heating, cooking, building envelope, and controls-based technologies. Although the program does not offer incentives for self-generation technologies (equipment that enables customers to generate or store energy on site), it does provide opportunities for participating customers to sign-up for the Self-Generation Incentive Program (SGIP). SGIP provides incentives for fuel cells, microturbines, and linear accelerators, among other technologies (this equipment must be installed after the 12-month monitoring period).
Eligible Customers
GRID-MAP serves SoCalGas’ commercial and residential customers. All Commercial customers who meet program requirements are eligible. The program is available to: Single Family, Multifamily, and Mobile/Manufactured Home Residential customers.
Project Incentives
Aggregators receive payments for projects based on the savings produced at time of year. As a program focused on aligning program payments with benefits to the utility system, projects that produce energy savings at times when “avoided costs” are higher, receive higher payments. In addition:
- projects with higher cost-effectiveness receive higher incentives and those with lower cost-effectiveness will see reduced incentives;
- projects for hard-to-reach (HTR) customers and those within disadvantaged communities (DAC) receive higher incentives;
- site-based NMEC projects receive lower incentives because of higher administrative costs.
See the following tables and downloadable spreadsheet for the program’s incentive rates.
All rates are subject to change.
This downloadable rates spreadsheet provides the table data in Excel format.
Aggregators receive the following payments:
- An Installation Payment equal to 40 percent of the Estimated Total Incentive – paid after Installation Approval;
- Semi-annual calendar Performance Payments calculated based on the net amount of earned incentives to date minus the Installation Payment and any prior Performance Payments.
