- Fuel: natural gas.
- Size: 1090 MW.
- Configuration: 2x2x1.
Project Description
In March 2018, Tampa Electric Company authorized Sargent & Lundy to begin work on the Big Bend Modernization Project. The overall scope of the project is to convert the coal-fired Unit 1 to a natural-gas combined-cycle electric generating facility, including associated transmission and interconnection facilities and natural-gas infrastructure.
Located on the site of the existing Big Bend Power Station, the pulverized coal unit is to be modernized into a 1090‑MW 2x2x1 combined-cycle configuration, utilizing two General Electric model 7HA.02 combustion turbines (CTs), two heat recovery steam generators (HRSGs), and major modifications to the existing Unit 1 steam turbine generator that is being repowered.
The existing condenser and circulating water system will be refurbished and reused and the water intake systems will be modified for 316b rule compliance. The existing coal-fired Unit 2 will be retired.
Project Scope
Sargent & Lundy’s wide-ranging scope spans detailed engineering, design, procurement, project management, and onsite construction management/commissioning oversight. Simple-cycle operation of the new CTs is scheduled for 2021, with combined-cycle operation of the repowered steam turbine generator in 2023.
