Meldahl Hydroelectric Project

The City of Hamilton, Ohio, and its partner, American Municipal Power, Inc. (AMP), together hold a license issued by the Federal Energy Regulatory Commission to develop a new, renewable energy, hydroelectric generating facility, calleMeldahl plant view 1 9-2014d the Meldahl Hydroelectric Project.  The Meldahl Project is located on the Ohio River, approximately 40 miles east of Cincinnati, at Foster, Kentucky, near Augusta, Kentucky. The Meldahl Project includes a 105 megawatt "run-of-the-river" hydroelectric plant, under construction at the Captain Anthony B. Meldahl Dam and Locks operated by the U.S. Army Corps of Engineers. At an estimated construction cost of $504+ million, the hydroelectric turbine powerhouse is being built on the Kentucky side of the river because the locks, used by river traffic, are situated on the Ohio side. The Meldahl Project’s proposed 138 kV transmission line will carry its electricity to the national electric grid by crossing the Ohio River and running approximately 2.2 miles to an existing PJM Interconnect in Clermont County, Ohio.

The Meldahl Project represents a significant economic development investment and will provide a new source of clean, zero emission electric generation. Hydroelectric plant construction will peak with more than 400 construction workers representing a variety of construction trades. Hamilton and AMP have turned the Meldahl Project site over to Alberici/Baker Joint Venture for construction of the facility. The Baker partner in the joint venture is Baker Concrete Construction, headquartered and highly respected in Butler County, Ohio, for which the City of Hamilton is County Seat.

Hamilton owns and operates its own municipal electric system, providing electricity to approximately 30,000 residential, commercial and industrial customers and is a founding member of AMP, its partner in the Meldahl Project.  AMP, a non-profit corporation, serves as a joint action agency for a consortium of electric generating and/or distributing cities located in Ohio and several other states. In addition to Hamilton, approximately 47 other cities through membership in AMP are participating in the Meldahl Project. Upon commercial operation, scheduled for 2015, Hamilton’s entitlement is 51.4% of the Meldahl Project’s electric output, with other AMP member communities being entitled to 48.6%.

Transmission Line and Substation Project Associated with the Meldahl Hydroelectric Facility 
On November 28, 2011, the Ohio Power Siting Board (OPSB) authorized the City of Hamilton and AMP to construct a 2.2-mile long 138-kilovolt (kV) electric transmission line in Clermont County. The new transmission line will connect the 105-megawatt Meldahl hydroelectric facility that is under construction in Bracken County, Kentucky to the existing 345-kV Zimmer-Spurlock transmission line in Ohio.

The Meldahl transmission line will provide southwest Ohio with additional low-cost power from a renewable energy resource and enhance service reliability for the region’s municipal electric customers. The project includes a supporting substation where the new line interconnects with the Zimmer-Spurlock line. AMP and Hamilton began construction on the line in 2012.

Meldahl Fun Fact: The Meldahl facilities, when completed, will be over 80 feet tall; however, the hydroelectric turbines and other generating parts must be installed to meet tolerances requiring accuracy within fractions of a millimeter!
