Florida

ESS runs a satellite office in Florida. Here is the grid it operates in.

How Florida makes its power

Natural gas fuels most of Florida's electricity, supplying roughly three-quarters of net generation as of 2024. Nuclear power provides about 11 percent from the Turkey Point and St. Lucie stations, while utility-scale solar has grown quickly and now makes up a small but rising share of the mix. Coal has fallen to a small fraction of generation as older plants retire.

Grid challenges

Florida's grid faces regular exposure to hurricanes and tropical storms, and utilities file storm hardening plans with the state that emphasize stronger poles, undergrounding, and smart grid technology. Steady population and load growth, together with a rapid solar buildout, are driving continued transmission and distribution investment. The peninsula also has relatively limited transmission ties to the rest of the Eastern Interconnection, and summer air conditioning load sets the annual peak demand.
