STORM COST RECOVERY ADJUSTMENT FACTOR
1.01
Purpose
The purpose of the Storm Cost Recovery Adjustment Factor (SCRAF) is to provide a mechanism
to recover from Customers the costs incurred by the Company in 2011 for Tropical Storm Irene
and the snowstorm in October 2011 pursuant to its settlement agreement in D.P.U. 10-170 (the
“D.P.U. 10-170 Settlement”). Such costs will be excluded from the Company’s storm fund
calculation and deferred at the Prime Rate for recovery in the SCRAF over a five-year period
beginning January 1, 2014.
Storm Cost Recovery amounts shall only include incremental costs, which are defined herein as
those actual and required costs directly attributable to the emergency response and not otherwise
represented or recoverable by NSTAR Electric d/b/a Eversource Energy in any other rate, charge,
or tariff.
1.02
Applicability of SCRAF
The SCRAF shall be applied to all kilowatt-hours (kWh) delivered by NSTAR Electric Company
d/b/a Eversource Energy to all Customers in the Greater Boston, Cambridge, South Shore, Cape
Cod, and Martha’s Vineyard Territories.
1.03
Effective Date of Annual Adjustment Factor
The date on which the annual SCRAF becomes effective shall be the first day of January of each
calendar year, unless otherwise ordered by the Department. The Company shall submit SCRAF
filings as outlined in Section 1.05 of this tariff.
1.04
SCRAF Formula
SCRAF = [SCRRR + PPRA + CC]/FkWh
Where
Recovery Year is the 12-month period beginning January 1 of each year in which the SCRAF is
in effect.
SCRAF =
The annual Storm Cost Recovery Adjustment Factor applicable in the recovery
year
SCRRR =
The balance of the revenue requirement for costs incurred by NSTAR Electric
d/b/a Eversource Energy in 2011 for Tropical Storm Irene and the snowstorm in
October 2011

The Past Period Reconciliation Amount which is defined as the difference
between (a) recoverable Storm Cost Recovery costs for previous years and (b)
