National Grid Files New Default Service Rates

National Grid has filed with the Massachusetts DPU new basic service rates for residential and commercial customers for the six-month period beginning April 1, 2017, and for industrial customers, for the three-month period beginning April 1, 2017

Taking into account pending changes to National Grid's Basic Service Administrative Cost Adjustment Factors (BSACFs) and Smart Grid Customer Cost Adjustment Factors (SGCCFs) which are the subject of another proceeding, the new rates are marginally lower than the current basic service rates for mass market customers (about 3 mills per kWh lower for the residential and commercial fixed rates)

The changes to the BSACFs and SGCCFs are proposed to be effective May 1, 2017

National Grid filed the new fixed basic service rates only reflecting both the current BSACFs and SGCCFs, as noted below.

Additionally, National Grid filed the "base" basic service rates, on a fixed and monthly basis, without the impact of either the BSACFs and SGCCFs adders (as noted below)

The rates remain subject to DPU approval
