N.E. grid leader cites dependence on natural gas

The region’s growing dependence on natural gas to generate electricity is a serious threat that could cause more frequent power outages and increase energy prices, Gordon van Welie, head of New England’s power grid operator, said in prepared testimony to Congress on Tuesday.

Van Welie, chief executive of ISO New England, told the House Energy and Commerce Committee that natural gas is used by power plant operators to generate more than half of the region’s electricity, largely replacing a diversified mix of oil, coal, gas, and nuclear power. Nuclear accounts for about one-third of the region’s electricity production.
