The facts, as filed.
On-site power changes the equation.
NextNRG has proposed an integrated data center and energy infrastructure campus spanning 1,600 acres — 400 acres for data center buildings, 1,200 acres for the associated energy generation and distribution infrastructure. The design allows phased deployment: operators could begin with 50 MW modules and scale toward 200 MW or more, reducing upfront capital risk. Additional expansion potential spans 6,000 nearby acres, which could put the eventual total well beyond 200 MW.
The on-site power generation model is less common in Florida than the "co-locate next to an existing utility plant" approach used by Project Tango (FPL West County Energy Center) and Fort Meade (Duke Energy Hines Complex). On-site microgrids can improve reliability and reduce the grid-upgrade cost borne by other ratepayers, but they raise separate permitting questions around air emissions from backup generators, interconnection with the grid, and the long-term environmental footprint of the energy infrastructure itself.
The project's site near Jacksonville International Airport may simplify some logistics — construction, workforce access, fiber connectivity — but places it in a higher-population-density region of Florida than Fort Meade or Okeechobee. Community response, as of mid-April 2026, has been more limited in public reporting than the Palm Beach County or Polk County fights.

Grid impact
On paper, an on-site microgrid model should mean less pressure on residential utility rates — NextNRG generates its own power rather than drawing 200+ MW from the existing FPL or JEA grid. In practice, the details of the interconnection agreement matter: whether excess power is sold to the grid, whether the microgrid serves as a backup during failures, and how permitting for new generation is handled.
Air and noise
On-site power generation typically means natural gas turbines, reciprocating engines, or fuel cells. Each has a different air emissions profile. If the 200 MW microgrid is gas-fired, air permitting through the Florida Department of Environmental Protection becomes a central input opportunity for residents. Noise from generators varies considerably by technology.
Workforce
The combined data-center-plus-energy-campus model could create more permanent operational jobs per acre than a pure data center, since power plants typically require more continuous staffing. This could affect the economic argument communities weigh against environmental and infrastructure costs.
