What EfficiencyOne does

EfficiencyOne is a federally-incorporated non-profit organization headquartered in Dartmouth, Nova Scotia, operating Canada's first energy efficiency utility under the Efficiency Nova Scotia franchise. The company delivers demand-side management (DSM) programs to residential, commercial, industrial, institutional, agricultural, and fisheries customers in Nova Scotia, funded primarily through a ratepayer-derived DSM Fund administered under a franchise granted by the Nova Scotia Minister of Energy in November 2014 and regulated by the Nova Scotia Utility and Review Board. Its program portfolio includes the HomeWarming program (free heat pumps and insulation for low-income households), Business Energy Rebates, the Custom Program serving over 100 industrial customers, Small Business Energy Solutions, the Smart Synergy demand response program with 50+ industrial and commercial clients, the New Home Construction program, and sector-specific initiatives such as the Fisheries and Aquaculture Energy Efficiency Innovation Fund and the African Nova Scotian Communities Retrofit Program.

The organization operates a portfolio of energy efficiency technologies including an Intelligent Efficiency Supply Chain pilot with Simptek Technologies using machine learning to match homeowners to programs and estimate savings, as well as virtual/remote home energy assessments that reduce the need for in-person EnerGuide audits. It also operates the On-site Energy Manager service with 21 dedicated energy managers embedded at client organizations, an Energy Manager placement program for institutional accounts such as Dalhousie University and the Nova Scotia Department of Health and Wellness, and the Demand Response (Smart Synergy) program that has reduced winter peak electrical demand up to 12 times per season. The wholly-owned subsidiary Halifax Climate Investment, Innovation and Impact Fund (HCi3), seeded with a $15 million endowment, $2.7 million operating grant, and an $18 million federal contribution, deploys grants and investments for Halifax-area emissions-reduction projects under the Low Carbon Cities Canada (LC3) initiative.

EfficiencyOne's business model is structured as a regulated non-profit utility. Franchise revenue flows through UARB-approved multi-year DSM Plans (currently 2023-2025, with 2027-2031 filed for approval in April 2026), while non-franchise revenue comes from cost-allocation arrangements with the Province of Nova Scotia, Natural Resources Canada (delivering the Canada Greener Homes Grant), the Nova Scotia Fisheries and Aquaculture Loan Board, and partnership programs with Nova Scotia Power such as Efficiency Insights. Pricing to end customers is free or subsidized, with rebates ranging up to $5,000 per household under the Canada Greener Homes Grant and free upgrades under HomeWarming. Since 2011, EfficiencyOne has delivered over $5.6 billion in lifetime energy savings to Nova Scotians, and its 2024 DSM Plan targets approximately $540 million in electricity bill reductions. The organization is led by an independent Board of Directors under the Canada Not-for-profit Corporations Act, with a current leadership transition in which COO Martha Casey will assume the President and CEO role effective 28 March 2026 following Stephen MacDonald's planned departure.

Peers

• NYSERDA (New York State Energy Research and Development Authority):

Broad incumbents

• Enbridge Gas Distribution: Enbridge Gas operates Ontario's largest natural gas utility and runs a portfolio of DSM programs for residential and business customers through the Ontario Energy Board. Comparable to EfficiencyOne as a regulated utility delivering ratepayer-funded energy efficiency and conservation programs, but at much larger scale and across multiple jurisdictions.
• BC Hydro Power Smart: BC Hydro Power Smart is British Columbia's in-house demand-side management program for residential, commercial, and industrial customers, run by the provincial Crown corporation. Comparable to EfficiencyOne's Efficiency Nova Scotia franchise as a vertically integrated utility-administered DSM portfolio, with similar residential/business program structures (rebates, custom, new construction).
• Mass Save: Mass Save is a Massachusetts consortium of electric and gas utilities and energy efficiency providers delivering statewide residential and business energy efficiency programs. Comparable to EfficiencyOne as a coordinated, regulator-mandated DSM delivery vehicle funded through ratepayers, with similar program types (Home Performance, HEAT Loan, rebates).

Direct peers

• Toronto Atmospheric Fund (TAF): TAF is one of the seven LC3 (Low Carbon Cities Canada) urban climate centres and uses grants and endowment-style investments to fund local GHG-reduction projects in Toronto. Most directly comparable to EfficiencyOne's HCi3 fund — same LC3 funding model, same mandate of municipal decarbonization investment, and similar governance via a non-profit board.
• Vermont Energy Investment Corporation (VEIC): VEIC operates Efficiency Vermont and three other statewide energy efficiency utilities under utility-regulation contracts, delivering DSM programs funded through a ratepayer charge. Closest international analog to EfficiencyOne's franchise model — same regulatory design, same multi-sector program mix, and same focus on transforming end-use energy consumption.
