The range of construction projects that are grounded in quality foundation work, substantial reinforced walls, and strong parking structures that are a result of Conco’s concrete services is extensive.  A few years ago, the woefully under-serviced energy market in Southern California was addressed when the General Electric Company, along with managing partner, the Calpine Corporation built a new energy plant.  Conco’s services were enlisted to help in the construction of the large plant.

Inland Empire Energy Center Construction

The 800MW, natural gas-fired Inland Empire Energy Center is capable of meeting the energy demands of close to 600,000 households and is located in Romoland, CA. in Riverside County.  The plant came online in 2008 and sits on 46 acres.   The architect and engineer for the project was Parsons E&C and the total cost of the project was $500 million.

The Inland Empire Energy Center is a state-of-the-art facility and was site for the “launch of GE’s most advanced gas turbine technology, the H System.”  This innovative technology “enables the H System to provide superior fuel economy and environmental performance.”*   According to GE, the result is that the efficient H system uses less fuel and produces fewer emissions than other large gas turbine systems.

Calpine Power was the construction manager, and when the plant came online, Calpine Energy became responsible for the marketing of the energy.  At some point, under a pre-arranged agreement, the Calpine Corporation will buy the plant from GE.   Conco was pleased to be a part of a project that serves the communities of Southern California and provided a means to reducing air pollution.
