Note: Cosumnes Power Plant and the cogen and peaker plants are SMUD-owned resources.

*SMUD's GHG emissions are estimated based on the amount of power generated at  SMUD's gas plants and power purchased from the Calpine Sutter gas plant.  The planned and actual GHG emissions from our fossil fuel generation reflect total emissions to serve SMUD customer energy needs and market sales to support California and other neighboring states. GHG emissions are estimated using the most recent emission factors that have been verified in accordance with the California Air Resources Board (CARB) Mandatory Reporting Regulation (MRR).

Zero carbon program and project statuses

We'll achieve our 2030 goal through the success of different projects, programs and activities. Utility-scale projects will help ensure we can continue to provide safe, reliable service using carbon free energy.

Participation in residential and commercial customers programs will help us bridge the gap to meet our goal and help improve our regional air quality. Program adoption depends on a variety of factors. Participation numbers may vary quarter-to-quarter depending on these factors.

We calculate an all-electric equivalent home by combining electrification projects such as a heat pump HVAC at one home, a heat pump water heater from another home and an induction cooktop from another home. Added together, they make one all-electric equivalent home. We also include 100% all-electric single family and multifamily homes.

To help us achieve our goal of carbon-free power by 2030, we're working on a variety of utility-scale projects to increase our portfolio of carbon-free energy and improve reliability. Below are projects we're currently working on or have completed.

 

Status Project name Added capacity Energy source Description
In Progress ESS 4 MW/
24 MWh
Battery Storage

Battery Storage pilot project in partnership with ESS, a manufacturer of long-duration iron flow batteries for utility-scale energy storage applications, will install a mix of long-duration energy storage (LDES) solutions integrated with our grid. Phase 1 pilot targets demonstrating up to 4 MW/24 MWh at our Hedge facility with 2 separate installations. The first is a 450 kW/2400 kWh storage system that was deployed in September 2023 and is undergoing operational testing. For the second installation, =design is underway for an approximately 3.6 MW/29 MWh (8-hour duration) storage system with installation planned for Winter 2025-2026.

In Progress Solano 4 91 MW Wind The project scope includes decommissioning Solano 1 by removing 23 wind turbines in April 2023. The project scope also includes the installation of 19 wind turbines (9 in Solano 4 East and 10 in Solano 4 West). Construction on the new turbines started in April 2023, with expected completion in May 2024. Once the Solano 4 project is complete, SMUD Solano Assets (Solano 2, 3 & 4) will have a total installed capacity of 300 MW.
In Progress Country Acres 344 MW/
172 MW
Solar/Storage

SMUD Board approved the Final EIR on April 20, 2023. Placer Planning Commission and Placer Conservation Authority Approved the Project and Mitigation Agreement on January 11 and 17, 2024, respectively. The Board of Supervisor approved the project on February 20, 2024. Construction is targeted to begin in the second half of 2024 and the project is scheduled to be online in 2026.

In Progress Coyote Creek 200 MW/
100 MW
Solar/Storage

SMUD is in contract with DE Shaw for the procurement of energy for the Coyote Creek project. DE Shaw is currently in the environmental review process. The scope of the Coyote Creek project includes 200 MW Solar coupled with 100 MW x 4hr battery storage. 

In Progress Sloughhouse 50 MW Solar SMUD is in contract with DE Shaw for the procurement of energy for the Sloughhouse project. The scope of the project is a 50 MW solar installation. Design, environmental review and permitting are in progress. The project is forecasted to be completed in mid-2025.
Complete (2023) Hedge 4 MW Battery Storage Commercial operation of the Hedge Lithium Ion Battery Energy Storage System began in January 2023. The system will provide 4 MW of electricity and 8 MW-hours of storage that can be tapped when other energy resources are strained—enough to power 800 homes for 2 hours with clean, renewable energy.
Complete (2023) Calpine 100 MW Geothermal January 2023 marked the beginning of the 10-year PPA of energy from Calpine’s operations at The Geysers, which adds 100 MWs of geothermal energy to SMUD’s portfolio—enough to power about 100,000 homes for a year. The Geysers is the single largest geothermal electric operation in the world.
Complete (2022) Drew Solar 100 MW Solar The Drew Solar Project, completed in 2022, is a 30-year Power Purchase Agreement (PPA) for 100 MW Solar. Located in Imperial County, it has an expected output of 282,000 MWh/year.
