Delivering reliable energy for today and tomorrow.

FPL is committed to delivering reliable service to our customers and properly planning for anticipated growth throughout the state. To do so, the company continues to invest in our energy grid. FPL is proposing to build an approximately 80-mile transmission line from Okeechobee to DeSoto counties.
