Because it might build a natural gas-fired power plant on the site, the Ohio Power Siting Board on Sept. 30 extended a certificate by 18 months for a Meigs County site where American Municipal Power-Ohio had once intended to build a coal plant.
In November 2008, the board issued certificates for a 960-MW pulverized coal project and related transmission infrastructure, with those certificates having five-year deadlines for construction to start. AMP-Ohio later shelved the coal project due to cost estimates that rose dramatically as it got closer to a construction start.
What the board on Sept. 30 did was extend the certificate in terms of the construction start by 18 months, until May 24, 2015, as it relates to the transmission facilities, so as to preserve an option for the gas-fired combined-cycle project. It did not extend the certificate as it relates to the power plant itself, since that was based on the specific attributes of a coal-fired plant.
AMP-Ohio would construct approximately five miles of double circuit 345-kV transmission line, including related facilities, to provide an interconnection for the proposed power plant. The new transmission line would be connected to the existing 345-kV Sporn-Muskingum River Transmission Line, located to the north of the plant site.
In it Aug. 26 motion for this extension, AMP-Ohio noted that it has met some of its power needs with a 2011 buy of the gas-fired, 707-MW Fremont power plant in Ohio. But it still has future capacity needs that might be met with a power plant at the Meigs County site. It noted that on July 19, it issued a request for proposals for new peaking and energy supply proposals to selected companies, and that within that RFP it indicated it is looking at its own self-build options.
