On behalf of Counsel to the Nova Scotia Utility and Review Board (NSUARB), Synapse assessed Nova Scotia Power's (NSPI) advanced metering infrastructure pilot proposal in 2017. NSPI requested approval to deploy advanced (“smart”) meters to up to 1,000 customers at a cost of $8.2 million. Ms. Alice Napoleon identified multiple issues with the proposal, including, among other things, that the pilot period would neither provide sufficient time for data collection nor cover the period of highest system demand; that the pilot’s size was not adequately justified; that complementary programs to help customers experience the benefits from implementation of AMI were omitted; and that the proposed network for the pilot is not consistent with the network that may be required for full implementation. The evidence concluded that the design of the proposed pilot would not provide a solid basis for determining whether the costs and benefits associated with AMI justify a full roll out. Ms. Napoleon recommended that NSUARB not approve the current pilot application based on the current record of evidence. To address deficiencies identified by Ms. Napoleon and others, NSPI withdrew its initial AMI application and stated its intention to submit an amended filing.
In October, 2017, NSPI submitted an application to implement AMI throughout its service area. The application requested Board approval of a capital work order for $133 million to replace about 495,000 conventional meters with smart meters over the period 2018 to 2020. In early 2018, Alice Napoleon submitted evidence on behalf of the NSUARB regarding NSPI's proposal. Specifically, the evidence considered: 1. cost effectiveness of the proposal, including the magnitude of and support for claimed benefits such energy savings associated with critical peak pricing; 2. the reasonableness of allowing a return on the conventional meters to be replaced; and 3. coordination with the energy efficiency utility, EfficiencyOne, to enable benefits of the meters to be realized. In response to this evidence, NSPI submitted a sensitivity analysis to more fully consider the downside risks. The Board approved NSPI’s proposal subject to conditions but disallowed a return on the existing meters.
