Santee Cooper’s goal was to meet their near term power demand  forecast while maintaining their status as the lowest cost producer of electricity in the State of South Carolina.

Santee Cooper has diversified electrical generation with nuclear, gas fired simple and combined cycle, coal, oil and solid waste land fill gas. Their economic model required the next economic fuel addition to be coal.

Worley Parsons scope of work was engineering, procurement, construction management, and startup (EPCM).

Cross is in a high seismic zone. After contract award, new law was promulgated significantly affecting seismic design. A complete change to subsurface design criteria resolved the issue and saved millions of dollars of construction cost and significant schedule impact. Subsequent to construction start of Unit 3, permitting delays resulted in Santee Cooper need for Unit 4 immediately following Unit 3. Creative construction planning, exercising of prior supply contract options, and responsive/creative engineering and procurement allowed a planned overlap of construction Units 3 and 4.
