NextEra Energy Resources' subsidiary La Frontera Ventures has divested its stake in two natural gas-fired facilities in US to Luminant, an affiliate of Energy Future Holdings (EFH), for nearly $1.55bn.

Located in the state of Texas, the two power plants include the1, 076MW Lamar Energy Center and 1,912MW Forney Energy Center and began commercial operations in 2000 and 2003 respectively.

The Lamar Energy Center features gas and steam turbines capable of generating electricity required to power more than one million homes.

The Forney Energy Center in Forney is designed to generate electricity using both gas turbines and a steam turbine to power more than 1.6 million homes.

Luminant CEO Mac McFarland said: "We’re delighted to add these two combined-cycle natural gas plants that will enhance our already diverse generation assets."

Luminant earlier said that the combined-cycle gas turbine power plants will complement its diverse energy portfolio that includes coal, natural gas and nuclear power, as well as significant purchases of wind-generated electricity.

A NextEra Energy Resources’ affiliate will continue to operate both of the facilities included in the sale for an initial period of up to one year.

NextEra Energy Resources operates wind, natural gas, solar, hydroelectric and nuclear power plants across the US.

The company also operates nuclear power generation facilities in New Hampshire, Iowa and Wisconsin as part of the NextEra Energy nuclear fleet, which is one of the largest in US.
