Canadians to Run Transmission Lines Under Lake Erie

LCG, Dec. 26, 2001--Two Canadian firms, TransEnergie U.S. Ltd. and Hydro One Delivery Services Inc., plan to put electric transmission lines on the floor of Lake Erie, connecting major Canadian and U.S. power grids by 2004, the Toronto Star reported Monday.

The two companies have jointly filed for a permit with the U.S. Federal Energy Regulatory Commission to install lines that would link Ontario with Ohio and Pennsylvania, the paper said. The project is called Lake Erie Link.

The plans call for up to three 325 megawatt lines from Nanticoke, Ontario, two to Erie, Pa., and one to Ashtabula, Ohio. The two-way lines make sense because power demands peak in Ohio and Pennsylvania in the summer while Ontario demands peak in the winter, said Michael Ernst, TransEnergie spokesman.

The Star said the armored cables would be buried 6 to 8 feet below the lake bed on a path that avoided sunken ships and other impedimenta. TransEnergie wants to dig the lines 50 to 60 feet apart. A high-pressure water system would drop the lines into trenches, and sediment would settle and close the trench.
