The NextEra power facility, as approved by the regulators, will use solar photovoltaic technology instead of the parabolic trough system previously planned.
Project developers said they still need approvals by the U.S. Bureau of Land Management so the project can be built on public land.
The installation could provide as many as 500 construction jobs at peak. As planned, the project would be built in four phases. Construction is expected to last four years.
