How GILBERT compares
With 608 MW of capacity, GILBERT ranks 8th among the 130 operating power plants Bywatts maps in New Jersey and is the largest of the 3 operating Oil plants in the state. It accounts for about 74% of New Jersey's operating Oil capacity and 4.2% of all operating capacity in the state. Nationally it is the 10th-largest of the 544 operating Oil plants in the database. Commissioned in 1974, it is older than 93% of the 128 operating New Jersey plants with a recorded commissioning year. Its operator, NRG REMA LLC, runs 2 operating plants in New Jersey totaling 820 MW. It shares Hunterdon County with 4 other operating plants, including FLEMINGTON SOLAR and FRENCHTOWN I SOLAR.
Under the same EIA plant code, EIA-860 lists 6 generators at the site with 512 MW of nameplate capacity (this page's HIFLD capacity figure is 608 MW). Net generation was 54.8 GWh in 2024 (a 1.2% capacity factor). Its generators came online between 1974 and 1996.

Weather peril exposure
GILBERT is a 608 MW oil power plant in Hunterdon County, NJ, operated by NRG REMA LLC, commissioned in 1974. Hunterdon County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.5 of 5 at the 13th national percentile. Strong wind is the leading peril, rated Relatively High by FEMA at the 91st percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to an oil plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
