*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).

Over 1,800 customers have installed battery storage, totaling more than 12 MW of storage in SMUD territory.
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 and was completed in May 2024. With the completion of the Solano 4 project, SMUD Solano Assets (Solano 2, 3 & 4) 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. |
