Niagara Mohawk d/b/a National Grid filed with the New York PSC revisions
to its annual reconciliation of purchased gas costs and gas cost recoveries, including an adjustment
to the calculation of the Company’s System Performance Adjustment (SPA).
Pursuant to discussions with the Department of Public Service Staff, the revised filing reflects an
adjustment to the annual usage for one of the Company’s dedicated line customers. In the original
filing, usage was estimated for the months of April and May due to a metering issue. In this filing,
the usage for the full twelve-month period is based on actual reads obtained from the customer’s
meter at the location. This revision resulted in a change to the LAUF from 2.933% to 2.491% and
a decrease of the LAUF credit from $4.3 million to $2.98 million. Accordingly, NiMo will
credit $18.9 million in over-collection, plus interest, to firm sales customers provided service under
Service Classifications (SC) 1, 2, 3, 12, and 13 through a $0.03193 per therm unit refund as set
forth on the Monthly Cost of Gas (MCG) Statement for the period January 1, 2020 through
December 31, 2020. For comparison, under NiMo's prior filing, NiMo had calculated a $0.03426 per therm unit refund to be set forth on the Monthly Cost of Gas (MCG) Statement for the period from January 1, 2020 through December 31, 2020.
Furthermore, NiMo said that its SPA, which is calculated as the difference between the LAUF upper dead-band
limit of 2.516% and the LAUF target of 1.516%, is now a surcharge of $2.98 million. Accordingly,
the Company will surcharge firm sales customers and firm transportation customers provided
service under SC 1, 2, 3, 5, 7, 8, 12, and 13, $0.002745 per therm, compared to $0.002814 per
therm in the original filing.
