An administrative law judge at the Federal Energy Regulatory Commission has recommended approval of the proposed three-way merger of WPL Holdings, IES Industries, and Interstate Power Co. to form Interstate Energy Corp.
Earlier this year, the companies and the FERC staff reached an agreement on market power mitigation. One stipulation was that the utilities had to contract for purchase of transmission capacity to interconnect the three utility systems. A portion of that capacity would be made available to other utilities on a first-come basis.
The utilities agreed not to build transmission lines to directly interconnect their systems until first constructing at least 400 megawatts of additional simultaneous transmission import capability into Wisconsin. To accomplish that goal, the utilities have proposed eight transmission projects. Administrative Law Judge Bruce I. Birchman also recommended that the partners investigate other projects that would increase transmission system import capability before constructing additional transmission lines across the Mississippi River if the eight proposed projects are not sufficient.
