Duke Energy Florida
Duke Energy Florida’s Crystal River Energy Complex includes coal fired and natural gas generating stations within a close distance from one another. The substation required a redesign and rebuild including a new control house. Commonwealth performed all the system protection and relay settings work for the substation including the generation plant lines. Commonwealth worked alongside the system planning and field construction group to provide all system protection services. These services included temporary settings being provided during construction phases as well.
Commonwealth also provided value to the project by proposing redesigning the configuration of how the generation is connected to the grid to meet breaker duty and critical clearing requirements. Commonwealth is involved in the non-standard relay settings development and special electrical calculations.
This project is currently underway with an expected completion in 2020.
