Decarbonization and Climate Change Mitigation Efforts of Cities and Energy UtilitiesList All
Utility Climate Mitigation Goal
In 2021, SDG&E announced its intention to produce power with zero carbon emissions by the year 2045. The year corresponds to California's target goal to get 100% of its electricity from carbon zero sources. To achieve this goal, SDG&E will need to reduce emissions by 3.85% annually from 2019 levels.
City-Led Efforts to Decarbonize the Electric Grid
The City of San Diego initiated the establishment of San Diego Community Power (SDCP), a Community Choice Aggregator that will serve the City of San Diego customers, as well as customers in the cities of Chula Vista, Encinitas, Imperial Beach, and La Mesa. As of summer 2021, SDCP will serve both commercial and residential customers. Additionally, the City is currently negotiating the 50-year electric and gas franchise agreement with SDG&E and intends to leverage the negotiation to increase deployment of renewable and distributed energy generation by the utility.
The city of San Diego is engaged in various regulatory proceedings at the California Public Utility Commission (CPUC) and advocates on behalf of the City and/or the community to encourage more renewable generation adoption. The City provided comments in response to the CPUC proceeding addressing microgrids and microgrid tariffs, and the City advocated in the Net Energy Metering proceeding for grandfathering of older net metering rates that the City used to calculate its cost-benefit analysis. The City also participated the regulatory process involving exit fees, which are fees charged to customers who buy electricity from government-run community choice programs rather than traditional utilities.
The City of San Diego is also working with SDG&E for renewable energy interconnection. SDG&E has agreed to put excess generation on the grid and receive credit through RES-BCT tariff. To meet the City’s 2015 Climate Action Plan’s goal of 100% renewable by 2035, City has implemented several privatized solar installations interconnected with utility grid where the City buys solar energy at a fixed bundled price which includes the Renewable Energy Certificates.
Clean Distributed Energy Resources
San Diego agreed to host eight solar-plus-storage microgrids on city facilities.
Municipal Renewable Energy Procurement
San Diego has installed 6 MW of solar capacity on city facilities.
City Renewable Energy Incentive and Financing Programs
Through Resolution R-298001, the city offers expedited permitting to residential and commercial projects that meet green building standards outlined in Policy Number 900-14.
Commercial and residential property owners may access property assessed clean energy (PACE) financing for both energy efficiency upgrades and renewable energy installations.

Efficiency Efforts in Water ServicesList All
Citywide Water Efficiency and Goals
The City of San Diego’s Department of Water Utilities offers water use calculators for household and landscape use. There are also rebate programs available for micro irrigation, turf removal, and rain barrels. The City of San Diego is also a member of the San Diego County Water Authority (SDCWA), which has been partnering with SDG&E for more than twenty years on administering water efficiency programs, such as low-flow showerheads, small business water efficiency equipment, leak loss detection, and education and outreach.
The City of San Diego’s Climate Action Plan has several water savings targets and long-term strategies to reach those targets. One target is to reduce daily per capita water consumption by 4 gallons by 2020 and 9 gallons by 2035 below 2010 levels. The core strategy is to implement an Outdoor Landscaping Ordinance that requires use of weather-based irrigation controllers. Supporting strategies to meet these targets are to record the annual volume percentage of recycled water used and planned to be introduced through 2035 and pursue additional financial resources and incentives for implementing energy and water efficiency measures identified by the conservation and ordinances, and to promote the expansion of greywater systems.
The City is also launching Pure Water San Diego, a phased, multi-year program that will provide one-third of San Diego's water supply locally by 2035. The Pure Water Program will use proven water purification technology to clean recycled water to produce safe, high-quality drinking water. The program offers a cost-effective investment for San Diego's water needs and will provide a reliable, sustainable water supply.
Water Plant Efficiency and Self-Generation
The City of San Diego’s Climate Action Plan encompasses both local water and wastewater utilities’ operations and include targets to reduce energy consumption at municipal facilities by 15% by 2020 and an additional 25% by 2035 below 2010 levels. Strategies to reach these targets include implementing a Smart Energy Management & Monitoring System for facilities to monitor and track energy consumption and using those results to identify opportunities for great efficiency and demand response along with pursuing LEED for Existing Buildings: Operation and Maintenance Certification for municipal facilities.
Since 2000, the Public Utilities Department has maintained a California Energy Commission-trained Energy Audit Team. Nearly all of the Department's major facilities have energy audit reports. The Department has invested an average of $400,000 per year in energy efficiency projects which have upgraded almost all of its emergency generators, department-owned administration buildings, as well as many of its largest pump stations and wastewater treatment plants. Projects have included lighting re-lamping and control, air conditioning system improvements, and process improvements.
The City of San Diego Public Utilities Department’s Wastewater Branch has multiple self-generating facilities and projects. The City also aims to capture 98% of wastewater treatment gases by 2035. At the Point Loma Wastewater Treatment Plant (PLWWTP), methane gas is captured to fuel two generators for a total capacity of 4.57 MW. The system also produces heat which is used to heat the plant’s digesters. The excess captured digester gas is sold to a private company that cleans the gas to utility standards, injects it into the utility company’s natural gas pipeline, and is used for resale by the privatizer. Methane capture is also utilized at the Metro Biosolids Center (MBC) and at MBC's privatized total cogeneration capacity of 9.6 MW. At the Metro Operation Complex, Department has two solar systems for a total capacity of 0.430MW. The Department’s Water Branch has multiple solar generation facilities. The Alvarado Water Treatment Plant has a 0.95MW privatized solar system. The Otay Water Treatment Plant has a 0.80MW privatized solar system, and the Bayview Reservoir has a City-owned 0.160MW solar system. A 1MW Solar System was recently installed on Clearwell #2 at the Miramar Water Treatment Plant.
