Southern Announces Solar Project to Supply Georgia EMCs

LCG, December 18, 2014-Southern Company subsidiary Southern Power announced yesterday its plan to develop a 131-MW solar photovoltaic (PV) project in Georgia. The electricity and associated renewable energy credits (RECs) will be sold under 25-year power purchase agreements (PPAs) to three Georgia electric membership corporations: Cobb Electric Membership Corporation (Cobb EMC), Flint Electric Membership Corporation (doing business as Flint Energies) and Sawnee Electric Membership Corporation (Sawnee EMC). Cobb EMC has contracted for approximately 101 MW of capacity, and Flint Energies and Sawnee EMC have each contracted for approximately 15 MW.

FootPrint Power Hires Iberdrola to Construct Combined-Cycle Plant in Salem

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.
