CO2 Gas plant emissions for load and market sales*
Bar chart titled '2026 Planned GHG = 1.6 million metric tons' showing greenhouse gas emissions contributions for Q1 2026. Planned emissions and cumulative emissions are shown as light blue and green bars, respectively. Three emission sources are also shown for the same quarter: Thermal Plant Contract in orange, Cosumnes Power Plant in blue, and Cogeneration and Peaker Plants in yellow. All values appear below 500 thousand metric tons. No data is shown for Q2 through Q4 of 2026. See table below for detailed information. 

 

  Q1 2026 Q2 2026 Q3 2026 Q4 2026
Thermal plant contract 34k MT CO2e --- MT CO2e --- MT CO2e --- MT CO2e
Cosumnes Power Plant 374k MT CO2e --- MT CO2e --- MT CO2e --- MT CO2e
Cogens and peaker plants 59k MT CO2e --- MT CO2e --- MT CO2e --- MT CO2e
 Total 467k MT CO2e --- MT CO2e --- MT CO2e --- MT CO2e

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.

Line chart titled '2026 All-electric Equivalent Homes' comparing the 2026 program plan with year‑to‑date actual progress from January through December. The planned values, shown in blue, rise gradually from 74.5 thousand homes in January to 79.0 thousand in December. Actual values, shown in yellow‑green, are available only through March, increasing slightly from 74.2 thousand in January to 74.7 thousand in March. After March, only the planned values continue, progressing steadily each month toward the year‑end target.   All electric homes by 2030
