Note: In a December 2017 letter to the IOUs the Executive Director of the CPUC declared that the U.S. District Court had declared that the Re-MAT program violated the Supremacy Clause of the U.S. Constitution by placing numerical limits on utility obligations to purchase power from QFs, and establishing a purchase price different than the utility's avoided cost. The letter instructed the IOUs to not accept or approve new Re-MAT contracts pending further CPUC action.
All investor-owned utilities and publicly-owned utilities with 75,000 or more customers must make a standard Renewable Market Adjusting Tariff (ReMAT) available to their customers. As the ReMAT is meant to help the utilities meet California's renewable portfolio standard (RPS), all green attributes associated with the energy, including renewable energy credits (RECs), transfer to the utility with the sale. Any customer-generator who sells power to the utility under this tariff may not participate in other state incentive programs. The tariffs will be available until the combined statewide cumulative capacity of eligible generation installed equals 750 megawatts (MW) for the general ReMAT program, and 250 MW for the bioenergy ReMAT program. Each utility will be responsible for a portion of those cumulative totals based on their proportionate sales.
The CPUC has regulatory authority over the investor-owned utilities, but not publicly-owned utilities. Therefore, the rules adopted by the CPUC do not apply to the publicly-owned utilities. Instead, the governing board of each publicly-owned utility is wholly responsible for developing their tariffs within the parameters established by the legislature in CA Public Utilities Code § 399.32 (formerly CA Public Utilities Code § 387.6). The collective share of the 750 MW program capacity established by the legislature for which the investor-owned utilities are responsible is 493.6 MW. The remaining 256.4 MW is to be divided between the publicly-owned utilities. Investor-owned utilities are solely responsible for the 250 MW bioenergy program.
Investor-Owned Utilities (General ReMAT program)
The California ReMAT allows eligible customer-generators to enter into 10-, 15- or 20-year standard contracts with their utilities to sell the electricity produced by small renewable energy systems (up to 3 megawatts (MW)). The CPUC has separated the technologies eligible to participate in the feed-in tariff into three project type categories: Baseload (bioenergy and geothermal), As-Available Peaking (solar), and As-Available Non-Peaking (wind and hydro). The ReMAT starting price is based on the weighted average of the three investor-owned utilities highest executed contract resulting from the Renewable Auction Mechanism (RAM) auction held in November 2011. Based on the results of that auction the starting price was $89.23 per megawatt-hour (MWh). As of July 2016, the current price for Baseload and As-Available Non-Peaking resources remains $89.23 per MWh; the current price for As-Available Peaking resources is $61.23 per MWh.
The CPUC built in price adjustment mechanisms to allow the program to adapt to changing market conditions. Interested generators must start by submitting a program participation request with the utility. The utility will establish a queue on a first-come first-served basis for each product type and will extend a ReMAT price offer to the applicants. The applicant can either accept or reject the contract. The price adjustments are only triggered if at least five projects with different developers for a certain product type apply. If no projects accept the Re-MAT, or less than 50% of the initial starting capacity for that project type accept the Re-MAT after its first two months, then the price will be escalated by $4 per MWh for the third and fourth months. The price will continue to escalate in subsequent two-month blocks until the subscription capacity is equal to 50% or more of the initial starting capacity for that project type. Similarly, if the program demonstrates excessive interest, the Re-MAT will be adjusted downward every two months.
Investor-Owned Utilities (Bioenergy ReMAT program)
SB 1122 of 2012 requires the investor-owned utilities to operate a separate ReMAT program for a cumulative total of 250 MW of bioenergy projects, separate from the wider 750 MW program. The legislation subdivided the 250 MW limit across different bioenergy sources:
The CPUC, in consultation with the California Energy Commission (CEC), the State Air Resources Board, the Department of Forestry and Fire Protection, the Department of Food and Agriculture, and the Department of Resources Recycling and Recovery, may reallocate the 250 MW requirement among the categories if they determine the allocations referenced above are not appropriate.
All publicly-owned utilities with 75,000 or more customers are required to develop feed-in tariffs by July 1, 2013. In determining the rate to pay under the tariffs, publicly-owned utilities must consider:
CA Public Utilities Code § 399.32 provides more guidance for publicly-owned utilities in developing their tariffs, including conditions in which the utility may limit the program.
Customers of publicly-owned utilities with 75,000 or more customers should contact their utility for more information. Customers of one of the investor-owned utilities can contact the appropriate program administrator for more information:
