CPS Energy is assessing how to replace aging power plants, whether to continue operating coal-powered units, and planning for population growth. Our generation planning process will identify the types of power generation resources to be added over the next several years. Planning objectives include system reliability, customer affordability, environmental sustainability, and other factors. CPS Energy will work with the Rate Advisory Committee to assess several generation planning options. CPS Energy is scheduled to make a recommendation on an updated generation plan to our Board of Trustees in late 2022.

Powering Our Community’s Future is an initiative designed to inform and encourage you to be part of the decisions we need to make for our community.


Current Power Generation Portfolio * (as of December 2022)

This is a diagram showing CPS Energy's various sources of power generation and their capacity, with renewables taking up 21% of capacity, gas at 46%, coal at 19%, and nuclear at 14%.

What is the timeline for retiring aging gas and coal plants?

A timeline for retiring CPS Energy coal plants, beginning in March 2025 and ending in March 2029.


The CAAP goal is to reach carbon neutrality by 2050. Emission reduction goals for 2030 and 2040 established in the CAAP can be met with our current plan to add more renewables and close the Spruce 1 coal unit. To achieve net-zero carbon emissions by 2050, most of our fossil fuel (gas and coal) generation may need to be retired or fitted with technology to capture carbon, if feasible. CPS Energy will continue to review proposals for zero-emission generation technologies such as hydrogen or geothermal energy, as the technologies become more feasible for utility-scale deployment.

Power Generation Diversification 1970-2021

An image showing how diversification of power generation has increased dramatically since 1970, especially in regards to renewables.

What portfolio concepts are CPS Energy and the RAC reviewing to replace aging gas and coal plants?**

There are 9 portfolio concepts in total, from using all gas to replace coal, a blended replacement, to concepts that use all renewables to replace coal.

** Each portfolio concept is a combination of a retirement schedule and potential technologies to meet capacity gaps.
