FirstEnergy Solutions Files Certification Letter with NRC Affirming Plan to Close Nearly 4,050 MW of Nuclear Generating Facilities

LCG, April 26, 2018--FirstEnergy Solutions (FES), a competitive generation subsidiary of FirstEnergy Corp., yesterday announced that it has filed a Certification Letter with the Nuclear Regulatory Commission (NRC) formally notifying the Commission of its decision to permanently deactivate its nuclear power plants over the next three years, citing "severe economic challenges." When the closures are combined, the reduction will total 4,048 MW of carbon-free, electric generating capacity. In 2017, the nuclear units contributed approximately 65 percent of the electricity produced by the FES generating fleet.

GE to Construct Hybrid Renewable Power Plant in Turkey

LCG, June 8, 2011--GE Energy (GE) announced that Turkey's MetCap Energy Investments selected GE's hybrid renewable-natural gas, combined cycle design for a 530-MW plant scheduled to commence operations in 2015. The energy facility will include wind turbines with a generating capacity of 22 MW, along with 50 MW of solar-thermal technology. The project site is in south central Turkey.

The solar thermal power system will be created by eSolar. GE announced on Monday that it would invest in eSolar to supply the solar portion of the system and that it would have licensing rights to sell and develop stand-alone solar thermal or hybrid power plants globally, using eSolar's technology.

eSolar employs a concentrated solar power (CSP) design. A field of sun-tracking, dual-axis heliostats reflects solar energy on a thermal receiver mounted atop a central power tower. The energy is used to create steam. In this hybrid design, the solar steam supplements the steam supply created from the gas-fired, combustion turbines. The high-pressure steam in turn drives the steam turbine to generate power.

Conceptually, the hybrid design adds solar power at a low incremental cost relative to building a stand-alone solar thermal power plant, as the incremental cost (above a stand-alone gas-fired combined cycle plant) is roughly the cost of the heliostats and power tower.
