This private member's bill rewrites how Nova Scotia evaluates demand-side management (DSM) under the Public Utilities Act and forces a regulatory reset. It directs the province's energy regulator and utilities to reassess which efficiency and electrification measures are cost‑effective and to renegotiate the utility DSM agreement accordingly.
The change matters because it reshapes the decision rule that determines which DSM programs get funded and how utility performance and cost recovery are justified—moving the focus beyond electricity savings to greenhouse‑gas impacts and the full energy costs facing households.
At a Glance
What It Does
The bill amends the DSM definition to factor in the social cost of greenhouse gas emissions as set by Environment and Climate Change Canada and to treat strategic electrification that lowers total household energy costs as DSM. It mandates the Nova Scotia Utility and Review Board to open a new proceeding to identify cost‑effective DSM and requires Nova Scotia Power and the franchise holder to enter or amend their DSM agreement to reflect the new definition.
Who It Affects
The changes target the provincial regulator, investor‑owned and franchised electricity utilities, DSM program designers and implementers, and households that could be offered electrification incentives. Energy consultants, appliance and heat‑pump vendors, and entities involved in natural‑gas or oil fuel markets will also feel program design shifts.
Why It Matters
By folding a federal carbon valuation and total household energy impacts into DSM economics, the bill alters which projects clear a cost‑effectiveness test and how benefits are monetized—potentially shifting investment toward electrification and greenhouse‑gas reductions even when electricity bills alone would rise.

What This Bill Actually Does
The bill makes three linked moves. First, it broadens the statutory definition of demand‑side management so regulators and utilities must consider greenhouse‑gas externalities and the full set of household energy costs when evaluating programs.
That means program benefits can include monetized climate impacts (using a federal estimate) and savings from replacing non‑electric fuels with electricity if the change lowers a household's overall energy bill.
Second, the bill forces the regulator to reopen DSM policy by ordering a fresh proceeding to identify cost‑effective DSM measures under the Public Utilities Act. That proceeding is not an advisory review; the Board must review and set the cost‑effectiveness framework that utilities will use to design programs and justify spending under the Act's existing DSM provisions.Third, the bill compels Nova Scotia Power Incorporated and the franchise holder to negotiate a new DSM agreement or amend their existing one so program terms, targets and cost‑recovery mechanisms align with the new definition and the Board's updated determinations.
The Act ties this contractual work back into the statute's existing agreement provisions so cost recovery, reporting and extension rules continue to apply.Together, these changes will alter how program administrators value measures (for example, adding carbon benefits to heat‑pump incentives) and will require utilities and the regulator to reconcile program design, rate impacts and distributional consequences under the Public Utilities Act's established agreement and oversight framework.
The Five Things You Need to Know
The bill requires using the social cost of greenhouse‑gas emissions as calculated by Environment and Climate Change Canada when valuing DSM benefits.
It replaces the phrase 'electricity costs' with 'total household energy costs, including costs from energy sources other than electricity' in the statutory DSM definition.
The Nova Scotia Utility and Review Board must open a new proceeding to determine cost‑effective DSM within 18 months after the Act comes into force.
Nova Scotia Power Incorporated and the franchise holder must enter into a new DSM agreement or amend an existing one within 18 months to reflect the amended DSM definition.
The bill preserves the application of the Public Utilities Act's Sections 79I to 79P to any new or amended DSM agreement, keeping existing rules on agreements, extensions and related requirements in force.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Heading change: 'Electricity' becomes 'Energy'
This edit swaps the chapter heading immediately before Section 79A from 'ELECTRICITY' to 'ENERGY.' It's a short textual change but signals a statutory shift from an electricity‑only frame to a broader energy perspective. Practically, it supports the subsequent definitional changes and clarifies legislative intent that DSM covers energy uses beyond the grid.
Definition expanded to include carbon costs and total household energy costs
The bill inserts two material changes into the DSM definition: first, it directs that the social cost of greenhouse gases—as calculated by the federal minister (Environment and Climate Change Canada)—be included when valuing DSM benefits; second, it changes the benefit metric from 'electricity costs' to 'total household energy costs,' explicitly recognizing savings on fuels other than electricity. That double change forces evaluators to monetize avoided emissions and to compare cross‑fuel life‑cycle costs when judging program economics.
Regulator ordered to reopen the DSM cost‑effectiveness proceeding
Regardless of prior Board work, the Nova Scotia Utility and Review Board must conduct a new proceeding within 18 months to determine what constitutes cost‑effective DSM under Section 79H. That proceeding will set the analytical framework—inputs, discounting, benefit categories and treatment of carbon values—that utilities and program administrators must use going forward.
Utility agreements must reflect the new definition; existing agreement rules apply
Within the same 18‑month window, Nova Scotia Power and the franchise holder must either sign a new DSM agreement or amend any agreement they entered or extended under the Act so the contract language, targets and reporting align with the expanded DSM definition. Sections 79I–79P remain applicable to these agreements, meaning the statute's existing procedures for negotiation, approval, extension and related obligations continue to govern implementation.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Households that switch to efficient electric technologies — The bill lets program valuations count full household energy bill reductions, which can make electrification incentives cost‑effective even if electricity bills rise, benefiting households that reduce total costs.
- Climate policy advocates and provincial planners — Monetizing avoided greenhouse gases within DSM creates a direct regulatory pathway to prioritize measures that lower emissions, aligning utility programs with provincial climate goals.
- Manufacturers and installers of electric appliances and heat pumps — Expanding eligible DSM measures and shifting incentives toward electrification increases market opportunities for these suppliers as programs are redesigned.
Who Bears the Cost
- Nova Scotia Power Incorporated and the franchise holder — They must renegotiate or update DSM agreements, redesign programs and adjust reporting and implementation practices to meet the new statutory test, creating administrative and program development costs.
- Ratepayers (potentially unevenly) — If programs expand or include higher up‑front incentives, costs will be recovered under existing statutory frameworks; without careful design, some customer classes could face disproportionate rate impacts.
- Nova Scotia Utility and Review Board — The Board must run a comprehensive proceeding and supervise the transition to a new valuation approach, increasing workload and requiring technical expertise on carbon valuation and cross‑fuel cost comparisons.
Key Issues
The Core Tension
The central dilemma is between improving decision‑making by internalizing carbon and accounting for whole‑household energy impacts, and the practical costs and distributional effects of doing so: a technically superior valuation can justify cleaner choices, but it raises methodological questions, administrative burdens, and potentially shifting costs across ratepayers and policy actors with no simple way to reconcile accuracy, equity, and timely program delivery.
The bill embeds the federal social cost of greenhouse gases into provincial DSM economics but does not specify which iteration or year of the federal estimate to use, how updates are handled, or how to reconcile federal assumptions with provincial conditions. Relying on a federal number simplifies standardization but risks misalignment if the federal methodology or time horizon differs from Nova Scotia's policy or market circumstances.
The statute also broadens the benefit metric to total household energy costs, which improves the policy alignment for electrification but raises data and methodological questions: how to measure non‑electric fuel consumption at the household level, how to account for timing and lifecycle costs, and how to treat households with mixed fuel portfolios.
The 18‑month deadlines create operational pressure. The Board's proceeding must design an analytical framework that feeds into negotiated agreements within the same statutory window, requiring coordination between regulator timelines and utility contracting.
Finally, the bill preserves the existing agreement regime (Sections 79I–79P), which means program cost recovery and reporting will still follow current statutory mechanics; that helps legal continuity but may constrain rapid redesign if those mechanisms assume electricity‑only metrics.
