See Our Annual Power Plant Operating Performance Rankings

NextEra Energy’s West County gas combined-cycle generating plant in Florida once again topped the annual Power Plant Operating  Performance  Report for 2015, according to the statistics released recently.

The West County facility led all comers, followed by gas combined-cycle (CC) stations owned by Southern Co., Duke Energy, Dynegy, TECO and Entergy in the top 10. NextEra had four plants in the CC top 10 and tied with Southern with six each in the top 20.

Pinnacle West’s Palo Verde plant in Arizona led the top 10 nuclear generators. Southern Co.’s  James H. Miller Jr. coal-fired plant in Alabama led those fossil-fueled stations.

The nation’s gas-fired combined cycle power plants produced 1.1 million GWh of power in 2015. That’s up 18.4 percent compared with 2014. Meanwhile, the average capacity factor for the nation’s fleet of coal-fired plants fell from nearly 60 percent in 2014 to 51 percent in 2015.

The Power Plant Operating Performance Report historically was published in the print edition of Electric Light & Power magazine through last year. In early 2016, EL&P was transitioned to an all-digital publication. From now on, the report will be printed in POWER ENGINEERING magazine.

For more on the report’s findings, read the story by Russell Ray, chief editor of Power Engineering at Power Engineering’s website.

This report is based on data and analysis provided by Energy Ventures Analysis. The data is collected from Form EIA 923 “Power Plant Report” and EPA’s Continuous Emissions Monitoring System (CEMS).
