Ohio board approves 1,353 MW of new gas-fired capacity

The Ohio Power Siting Board (OPSB) on May 1 authorized Oregon Clean Energy LLC to construct a new natural gas-fired combined-cycle facility in Oregon, near Toledo, Ohio.

“Today’s approval of the Oregon Clean Energy Center will add much-needed generating capacity to northern Ohio,” board Chairman Todd Snitchler said in a May 1 statement. “The facility will take advantage of cleaner-burning natural gas, at today’s affordable prices, further enhancing Ohio’s diversified energy portfolio.”

The 799-MW Oregon Clean Energy Center will utilize advanced gas turbine and combined-cycle technology to generate electricity. Oregon Clean Energy plans to begin construction in June and place the completed facility online in May 2016, the board noted.

Oregon Clean Energy’s application stated that during construction of the $860m project, an estimated 532 construction industry jobs will be created. During operation, the facility will employ 25 full-time workers.

Also on May 1, the board authorized Rolling Hills Generating LLC to increase the capacity of its existing natural gas-fired facility in Wilkesville, Ohio, from 860 MW to 1,414 MW. 

To achieve this capacity increase, Rolling Hills will convert four of the facility’s five existing combustion turbines from simple-cycle to combined-cycle mode. Upon completion, Rolling Hills will use the upgraded turbines to serve intermediate or baseload power demands. It will continue to use the remaining simple-cycle turbine to provide peaking power to the wholesale power market.

The proposed conversion is estimated to cost $865m and would result in a combined-cycle natural gas-fueled generating facility with a capacity of 1,414 MW. The applicant proposes to commence construction in the first quarter of 2014 and begin commercial operation in the summer of 2016, said a February report from the board staff about some minor stipulations that the board should put in any project approval.

Conversion of the RHGS would use all five of the existing Siemens 501FD2 natural gas-fired combustion turbine generators. One combustion turbine would remain in simple-cycle configuration with a nominal output of 172 MW. Four of the five combustion turbines would be coupled to Heat Recovery Steam Generators and each would be equipped with 550 million British thermal units per hour (MMBtu/hour) duct burners. Each pair of gas combustion turbines would be combined with HRSGs and a steam turbine generator set to create 2×1 power blocks, each with a nominal output of approximately 621 MW.
