Encina Power Station (EPS) was a large natural gas and oil-fueled electricity generating plant in Carlsbad in San Diego County, California.

[1] EPS sits on the southern shore of the outer segment of Agua Hedionda Lagoon; once a stinking pool at low tide due to development of Highway 101, it was opened to a continuous tidal flow to create a cooling system that was constructed along with the plant.

Home to blue herons, ibises, and a multitude of aquatic life, the lagoon is attached to the ocean and other waterways through rising tide levels and various small creeks.

[3] NRG had announced plans to expand Encina Power Station with the construction of a new 588-megawatt plant on a plot of land adjacent to the current site.

[6] The closing of the San Onofre Nuclear Generating Station (SONGS)[7][8] about 30 miles north[9] led to city officials approving the new state-of-the-art power plant in January 2014.
