Marcy Reed, president of National Grid Massachusetts, said she supports the construction of two new natural gas pipelines into the region to bring down electricity costs and to allow more customers to shift to gas for heating and cooking. She said she would welcome hydroelectricity from Canada, but stressed that the state’s current subsidies for renewable energy are not sustainable.
She said the cost of one form of subsidy, called net metering, is expected to double in National Grid’s service area from $35 million in 2014 to $71 million this year. She said the cost of solar renewable energy credits is expected to rise from $59 million in 2015 to $228 million this year. She estimated the cost of solar subsidies will be borne by the utility’s non-solar customers over the next six years to the tune of $2 billion.
