M09096 · Approval of a Supply Agreement for Electricity Efficiency and Conservation Activities between EfficiencyOne (E1) and Nova Scotia Power Inc.(NS Power), the establishment of a final agreement between the parties, and approval of a 2020-2022 Demand Side Management (DSM) Resource Plan

AI summary

The dominant document in this filing is a comprehensive set of 2018 DSM program evaluation reports prepared by evaluator Econoler for Efficiency Nova Scotia, covering residential programs (Appliance Retirement, Instant Savings, Home Energy Assessment, Green Heat, Efficient Product Installation, New Home Construction), business/non-profit programs (Business Energy Rebates, Custom Incentives, EMIS, SEM, Small Business Energy Solutions), and a Codes and Standards impact assessment — the E-5 document was provided as a section map only and was not read in full.
The evaluation methodology employed by Econoler included 92 stakeholder interviews, participant phone surveys, interceptcept surveys at retail (for LED products), 211 on-site visits, project file reviews, HOT2000 simulation reviews, billing analyses, unitary savings reviews, and net-to-gross ratio calculations incorporating free-ridership and spillover measurement across all program components.
Multiple large spreadsheet attachments (E-3-(i) through E-3-(xii)) were filed as responses to NSPI information requests IR-9, IR-18, IR-30, IR-31, IR-32, IR-52, IR-64, and IR-90, containing detailed technical tables on measure-level unit savings, participation projections, net-to-gross factors, cost data, and energy efficiency resource assessment model inputs used to support the proposed 2020–2022 DSM Resource Plan.
The Codes and Standards evaluation component assessed 2018 energy savings at the meter attributable to regulations covering incandescent lamps, LED street lights, new building energy codes, clothes washers, general service reflector lamps, general service fluorescent lamps, and fluorescent lamp ballasts — providing a separate stream of DSM credit beyond incentive-based programs.
The heat pump market evolution analysis within the Green Heat and residential program evaluations tracked mini-split heat pump free-ridership trends, market share growth, and price trajectories, findings that directly bear on the design of the proposed 2020–2022 plan incentive levels; the IR spreadsheets similarly carry heat pump cost and participation data across multiple scenarios.
