Mega Project Announced to Deliver Wind Power from Wyoming to Southern California

LCG, September 25, 2014-An $8 billion project was announced earlier this week as a solution to satisfy the future electricity needs of the Southern California Public Power Authority (SCPPA). The mammoth project includes a 2,100-MW wind farm in Wyoming, from which power generated would be delivered to California via a new electric transmission system, with a compressed air energy storage (CAES) facility installed in Utah to compensate for the intermittent nature of wind power. The entire project could be operational by 2023.

EPA Extends Comment Period for Clean Power Plan

LCG, September 18, 2014-The Environmental Protection Agency (EPA) announced Tuesday a 45-day extension of the public comment period for the Clean Power Plan, the EPA's proposed rule to limit CO2 emissions from existing coal-fired and gas-fired, combined cycle power plants. The mid-October deadline is now set for December 1, 2014. The EPA stated that it has already received over 3.5 million comments on the proposal. The schedule still includes a release of the final plan by June 2015.

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.
