DERBY — The Vermont utility building a 21-turbine wind power project on Lowell Mountain is facing a potential $11 million cost increase because of transmission upgrades requested by the operators of the New England electric grid.
Green Mountain Power estimates the project will cost about $150 million. But the price may jump by about 7 percent because of a recent decision by ISO-New England, which operates the regional grid.
ISO concluded that the utility will need to invest in a new voltage control system to balance the impact of electricity flowing into the grid.
Utility spokeswoman Dorothy Schnure said it doesn’t agree with ISO’s conclusion. She tells Vermont Public Radio Green Mountain Power is still talking with them about whether there are less expensive alternatives.
