New U.S. power plants expected to be mostly natural gas combined-cycle and solar PV
New U.S. power plants expected to be mostly natural gas combined-cycle and solar PV EIA's long-term projections show that most of the electricity generating capacity additions installed in the United States through 2050 will be natural gas combined-cycle and solar photovoltaic (PV). Onshore wind looks to be competitive in only a few regions before the legislated phase-out of the production tax credit (PTC), but it becomes competitive later in the projection period as demand increases and the cost for installing wind turbines continues to decline.
