Expanding Our Clean Energy Mix

Investing in a Sustainable Future

JEA is committed to delivering reliable, sustainable utility services that meet our community’s growing energy and water needs. To support this commitment, we are investing in a new combined cycle plant, an important part of JEA’s long-term strategy to diversify our energy mix, strengthen electric grid reliability, and meet increasing energy demand in Northeast Florida.

Benefits of Combined Cycle Technology

Combined cycle technology uses both a gas turbine and a steam turbine to generate electricity. Waste heat from the gas turbine is captured and reused to power the steam turbine, making the process more efficient than traditional generation methods and resulting in increased electric generation, fewer emissions, and lower operating costs.

• Produces lower carbon emissions per megawatt-hour, supporting a cleaner energy future.
• Expands JEA’s energy mix, allowing us to respond quickly to changes in customer demand.
• Combined cycle units can start up and reach full power faster than traditional plants, improving electric grid reliability.
• Lower operating costs help keep rates more stable over the long term, minimizing future impacts on customers.
• Supports local economic growth by providing a reliable energy foundation that attracts new businesses and sustains jobs.

About the Project

The new combined cycle plant will be built at JEA’s St. Johns River Power Park site. SJRPP Units 1 & 2 were decommissioned in 2019 to reduce costs and support the transition to cleaner energy. The new combined cycle units, SJRPP Units 3 & 4, will have the capacity to generate 675-megawatts, which is equivalent to powering an estimated 300,000 homes. SJRPP Units 3 & 4 are scheduled to begin generating electricity by 2031.
