Southern California Edison launched its third Disadvantaged Communities Green Tariff and Community Solar Green Tariff request for offers. SCE is soliciting energy from solar projects located in disadvantaged communities as specifically defined in the RFO document. Procurement for the DAC-GT and CSGT programs will run simultaneously and be conducted through a competitive solicitation. Consistent with the DAC Resolution, each program will have separate capacity allocations and bid requirements. SCE will hold two RFOs each year until the program caps—56.5 MW for DAC-GT and 14.63 MW for CSGT—have been met. The submission deadline is May 3 at 12 p.m. and information can be found on the DAC RFO website.
The Rialto Bioenergy Facility became operational and began supplying Southern California Gas Co. with renewable natural gas effective March 19. Anaergia, which owns the San Bernardino County facility said it will produce up to 985,000 MMBtu per year from landfill waste treated using a combination of anaerobic digestion and proprietary technologies. The company estimates roughly 300,000 tons of waste per year will be diverted from local landfills to produce RNG. A new 1-mile pipeline connects the facility to an existing SoCalGas pipeline. The utility said Rialto is the fifth project from which RNG has been injected directly into its natural gas transmission system.
Eric Little has been appointed director of regulatory affairs for the California Community Choice Association, where he will oversee the development, implementation and management of the organization's regulatory strategies, CalCCA said March 24. He comes to the position from Southern California Edison, where most recently he served as the utility's manager of CAISO and greenhouse gas markets. He was previously manager of market design and regulatory policy at CAISO.
Agreements have been finalized to progress to the next phase of development of a municipal microgrid for the City of Rialto, according to a March 17 announcement by the city, Rialto Water Services and Veolia North America, which are partners on the project. Although no indication of the ultimate capacity of the facility was provided in the joint news release, the microgrid will use a combination of biogas cogeneration, solar power and backup battery storage to supply electricity for the city's wastewater treatment plant, which treats roughly 7 million to 8 million gallons of sewage each day. The project is expected to cost about $8 million and will be completed in 2024. Veolia called the project "one of the first of its kind in California" and said it will provide the city "greater energy independence, resilience and efficiency to protect its essential wastewater treatment system." The microgrid project is expected to save the city $350,000 per year in energy costs and to reach its average return on investment in about eight years.
