Nstar To Combine POR Rates Into Single Discount Applicable To East, West Service Areas

Nstar (Eversource) has filed new proposed purchase of receivables discount rates (standard complete billing percentages) to be effective May 1, 2019.

In doing so, Nstar proposes to consolidate the POR discounts for its east and west (WMECO) service areas, for each customer class, into a single discount per customer class across its entire service area

The rates remain subject to DPU approval.

The proposed May 1, 2019 Nstar Massachusetts POR discounts are:

Nstar - East & West, May 1, 2019 (Proposed)
              Residential  Commercial  Industrial
Uncollectible    1.22%       0.19%       0.03%
Admin Cost       0.00%       0.00%       0.00%
Reconciliation  -0.28%      -0.07%     [-0.11%]*
Total            0.94%       0.12%       0.03%*

* Pursuant to past practice, Nstar will set the total industrial discount equal to the Uncollectible discount of 0.03%. Rather than incorporating the reconciliation refund amount into the POR discount, Nstar will make a one-time payment to each affected retail supplier serving industrial customers in Nstar's service territory.

Without the proposed consolidation, the POR discounts would have been as follows for each rate division, effective May 1, 2019

Nstar - East, May 1, 2019 (Illustrative)
              Residential  Commercial  Industrial
