MANCHESTER, N.H. — Energy leaders reiterated Wednesday the need for more power sources in New England, a fact made more acute by potentially record-high electricity prices coming this winter.

Representatives from ISO New England, the Public Utilities Commission and the state’s major utilities gathered at an event hosted by the Business and Industry Association to discuss the region’s energy challenges. Consumers are now facing a third winter with record power prices, said Andrew Gillespie, principal analyst at ISO New England, which runs the region’s power grid.

The lack of capacity demonstrates a need for more natural gas pipeline projects into New Hampshire and the region, experts at the event said. As weather gets colder and the gas utilities use more of the available natural gas, electric companies see their supply shrink, causing prices to rise. Kinder Morgan and Northeast Utilities have proposed natural gas pipelines to ease the crunch.

New England’s use of natural gas is steadily on the rise. In 1990, about 5 percent of New England’s energy capacity was fueled by natural gas. In 2013 that rose to 55 percent, and the figure is expected to hit 87 percent by 2037, PUC commissioner Bob Scott said. Four energy generators, including the Vermont Yankee nuclear plant and the Salem Harbor coal and oil plant, have been mothballed or are scheduled to go offline, further reducing the region’s energy supply.

New England paid $3 billion in additional costs last winter due to limited capacity, with New Hampshire bearing 9.5 percent of the increase, Scott said.

Beyond increasing capacity, both the state and ISO New England are pushing for reforms to increase efficiency and base pricing on how well the power generators perform. By 2018, ISO New England hopes to have reforms in place that ensure more reliability from its generators. New England receives energy from roughly 350 generators.
