The Public Utility Commission of Texas has approved a $370 million loan for NRG Energy's Greens Bayou facility, which is expected to expand natural gas-fired power generation by 455 MW and complete by 2028. The project, part of the Texas Energy Fund program, will add to an existing generating station near Houston and benefit from a 3% interest rate over 20 years, covering nearly 60% of the estimated $617 million total cost.
