Smithland Hydro Plant

The Smithland Hydroelectric Project is a 76 MW run-of-the-river hydroelectric power plant providing renewable generation to the region. The plant is located near Smithland, Kentucky.

The Smithland Project diverts water from the existing U.S. Army Corps Smithland Locks and Dam through bulb turbines anticipated to generate an average annual output of approximately 379 million kilowatt-hours (kWh). The site includes an intake approach channel, a reinforced concrete powerhouse and a tailrace channel. The powerhouse houses three horizontal bulb-type turbine and generating units with an estimated total rated capacity of 76 MW. A 2-mile-long 161 kV transmission line interconnection connects the plant to MISO.

Smithland is located approximately 62 river miles upstream of the confluence of the Ohio and Mississippi rivers, in Livingston County, Ky. The Smithland hydroelectric plant is on the Kentucky side of the Ohio River, on the opposite shore of the locks.

The plant reached full commercial operation in September, 2017.

Greenup Hydro Facility

The Greenup Hydroelectric Facility is a 70.2 MW power plant located near Portsmouth, Ohio. In connection with the development of the Meldahl Project, Hamilton agreed to sell and AMP agreed to purchase a 48.6 percent undivided ownership interest in the Greenup Hydroelectric Facility. Hamilton retains title to a 51.4 percent ownership interest in the Greenup Hydroelectric Facility. Forty-seven AMP member communities are participating in the project.

Willow Island Hydro Plant

The Willow Island Hydroelectric Project is a 44 MW run-of-the-river hydroelectric power plant that provides renewable generation to the region. The facility is located near St. Marys, West Virginia, on the Ohio River.

The Willow Island Project diverts water from the existing U.S. Army Corps of Engineers Willow Island Locks and Dam through bulb turbines anticipated to generate an average annual output of approximately 239 million kilowatt-hours (kWh). The site includes an intake approach channel, a reinforced concrete powerhouse and a tailrace channel. The powerhouse includes two horizontal bulb-type turbine and generating units with an estimated total capacity of 44 MW.

The Willow Island Locks and Dam are located in Pleasants County, West Virginia, approximately 162 river miles downstream of Point Bridge, Pittsburgh. The Willow Island hydroelectric plant is on the West Virginia side of the Ohio River, on the opposite shore of the locks.

The plant reached full commercial operational in February 2016.

AMP Fremont Energy Center

The AMP Fremont Energy Center (AFEC) is a 675 MW natural gas combined cycle (NGCC) facility in Fremont, Ohio. As an intermediate power source, AFEC has a capacity of 512 MW (unfired) and includes duct-firing that allows an additional 163 MW of generation during peak demand periods. AFEC consists of two combustion turbines, two heat recovery steam generators and one steam turbine and condenser.

AMP purchased the facility in July 2011 from FirstEnergy Generation Corp., a subsidiary of Akron-based FirstEnergy Corp. (NYSE: FE).

AMP owns 90.69 percent of AFEC on behalf of 86 participating AMP member utilities in seven states and 4.15 percent on behalf of the Central Virginia Electric Cooperative. The Michigan Public Power Agency owns the remaining 5.16 percent.

The plant reached full commercial operation in January 2012.

Prairie State

The Prairie State Energy Campus is a two-unit, supercritical coal-fired power plant designed to have a net rated capacity of approximately 1,582 MW and associated facilities in southwest Illinois. AMP is the largest equity owner of the facility at 23.26 percent, which translates to 368 MW. The remainder of the ownership group is comprised of power entities with a similar mission to AMP. Sixty-eight AMP member communities participate in the project. 

The plant reached full commercial operation in 2012.

Belleville Hydroelectric Plant (OMEGA JV5)

The Belleville Hydroelectric Plant is a 42 MW run-of-the-river hydroelectric power plant providing renewable generation to the region.

The Belleville plant diverts water from the existing U.S. Army Corps of Engineers’ Belleville Locks and Dam. Besides the 42 MW Belleville Hydroelectric Plant, the joint venture consists of approximately 26.5 miles of 138-kilovolt transmission facilities and fifteen 1.8 MW diesel reciprocating generating units. In May 2016, the 15 diesel units were restricted to emergency use only generation. During 2017, the participants approved selling the diesel assets, and sale and decommissioning is currently in progress.

The Belleville Locks and Dam are located near Belleville, West Virginia, southwest of Marietta, Ohio. The Belleville Hydroelectric Plant is on the West Virginia side of the Ohio River, on the opposite shore of the locks.

The plant reached full commercial operation in 1999.
