MONCKS CORNER, S.C. – Santee Cooper has undertaken a major capital project that primarily relies on South Carolina-located companies and resources to increase environmental protections at its two coal-fired generating stations in compliance with U.S. Environmental Protection Agency (EPA) rules.
Santee Cooper will spend an estimated $300 million on new wastewater treatment systems at Cross Generating Station (CGS) and Winyah Generating Station (WGS). Approximately $220 million of the total will be spent with companies with a major South Carolina presence.
Following a competitive bid process, Thompson Construction (Sumter) was awarded the primary contract. Santee Cooper will also utilize the services of Stantec (North Charleston), Fisher Tanks (Leesville), Nucor (Huger) and Palmetto Pile Driving Inc. (Charleston). The project will also employ over 180 workers at each location.
“Implementing this project is not just about meeting regulatory standards, but also about committing to ensuring a healthier and more sustainable future,” said Mike Finissi, Santee Cooper Chief Operations Officer. “The opportunity to utilize in-state resources for this project aligns with Santee Cooper’s mission.”
Santee Cooper received necessary DHEC approvals in mid-2023, equipment was purchased by the end of 2023, and construction began early in 2024.
The anticipated completion of construction is 3Q of 2025, with the systems fully operational by Dec. 31, 2025.
