Fluor Corp. has signed a memorandum of understanding with Boston-based Clean Energy Future LLC to provide development services for the company's next natural gas-fired power plants in Ohio.

Clean Energy is moving forward with the Trumbull and Oregon Energy Centers in Northeast and Northwest, OH, respectively. The company is already constructing two other gas-fired facilities in Lordstown, OH, and Oregon, OH, where the next plants are planned.

Under the agreement, Fluor said it would provide permitting and development services for the projects. Once they've secured financing and regulatory approval, Fluor said it would provide engineering, construction and commissioning for both plants.

"These two facilities will represent the fourth and fifth such CCGT (combined-cycle gas turbine) projects developed by Clean Energy Future in Ohio, and the sixth and seventh in the PJM Interconnection region," said Clean Energy Future President Bill Siderewicz. "Fluor will be working in partnership with our other team members including Siemens Energy, Siemens Financial Services and BNP Paribas."

Irving, TX-based Fluor is a global engineering and construction company that has built 50,000 MW of gas-fired power over the last 20 years. Construction of the 940 MW Trumbull Energy Center and the 955 MW Oregon Energy Center is expected to begin in 2018, with both projects slated for operations in 2020.

Clean Energy also led development of the 869 MW Oregon Clean Energy facility that's currently under construction in Northwest Ohio. That facility is expected to enter service next year. It also spearheaded the 940 MW Lordstown Energy Center in Northeast Ohio, which broke ground over the summer and is expected to be operational by 2018. Both of those facilities will cost more than $800 million to build.

A rush is on to replace aging coal- and gas-fired power in the Appalachian Basin, where dozens of facilities have been approved or proposed in recent years in Ohio, Pennsylvania and West Virginia.
