Central Maine Power and Maine Public Service have asked the ISO New England to review the feasibility of a transmission line that would link northern Maine with the regional grid and create a path for wind power to flow to load centers in southern New England.
Tim Brown, MPS director of corporate planning and regulatory affairs, said Thursday that the line, expected to be in excess of 100 miles, would allow transmission of more than 500 MW of wind power, most of it still in planning.
While the idea of connecting northern Maine to the regional grid has been discussed for years, it has taken on a new significance given the difficulty utilities and merchant generators have encountered when they’ve attempted to build plants in the high-demand southern New England states.
In addition to growing demand, Connecticut, Massachusetts and Rhode Island have renewable portfolio standards, which create pressure for more large scale wind. But no major projects have been built in southern New England. In northern Maine, about 42 MW of wind is operating and an additional 500 MW has been proposed.
If the line is not built, Brown said wind electricity in northern Maine could be routed into Canada then into southern New England. That, however, would require major upgrades to grid interface between MPS and New Brunswick Power. Brown said the utilities expect the ISO impact study to be completed by the end of 2007.
