While construction for a proposed pipeline across the northern portion of Massachusetts wouldn’t begin until April 2017, environmental groups are already expressing opposition. The proposal is to upgrade and expand the existing Tennessee Gas Pipeline covering parts of New York, Massachusetts, Connecticut and New Hampshire.

New England's electric grid operator says a lack of pipelines is making natural gas costlier, pushing up wholesale electricity prices in the region by 55 percent last year.

ISO-New England said Tuesday that the average price of wholesale electric energy rose to $56.06 per megawatt hour, up from a historic low of $36.09 in 2012.

Natural gas is the predominant fuel used to generate the region's electricity, amounting to about 46 percent of generation in 2013. Wholesale power prices tend to track the price of natural gas.

Vermont's Green Mountain Power wants permission to install equipment that will boost the amount of electricity that its turbines in the Lowell Mountain wind project can put out in the New England grid.

The Caledonian-Record reports that Lowell wind operators noticed Tuesday that three of the 21 turbines were not producing electricity. They said capacity has been curtailed by ISO-New England, which runs the New England grid.
