Canada's only major privately-owned provincial utility — with some of the country's most volatile rates. Here's what you actually pay and why solar makes sense.
Nova Scotia has the highest electricity rates in Atlantic Canada — and one of the most unique electricity systems in the country. Unlike every other province, NS Power is privately owned by Emera Inc., and subject to a quarterly Fuel Adjustment Mechanism that makes bills less predictable than anywhere else in Canada. At approximately 19.1¢/kWh blended, Nova Scotia offers solid solar ROI — and solar's fixed-cost generation is particularly compelling as a hedge against the rate volatility that NS Power customers experience year-round.
NS Power's residential rates are regulated by the Nova Scotia Utility and Review Board (UARB). The rate structure has three components — a fixed customer charge, an energy charge, and the quarterly Fuel Adjustment Mechanism.
| Rate Component | Rate (2026) | Notes |
|---|---|---|
| Customer Charge (fixed) | ~$10.26/month | Fixed monthly fee regardless of consumption |
| Energy Charge | ~15.5¢/kWh | Base energy rate before FAM adjustment |
| Fuel Adjustment Mechanism (FAM) | Variable quarterly | Adds or subtracts based on actual fuel costs |
| Effective Energy Rate (incl. FAM) | ~17.0–18.0¢/kWh | Varies quarterly with fuel markets |
| HST | 15% | Nova Scotia's harmonized sales tax on electricity |
| All-In Blended Average | ~19.1¢/kWh | Including customer charge, FAM, and 15% HST |
⚠️ HST Impact: Nova Scotia's 15% HST on electricity is one of the highest tax rates on power in Canada. Ontario charges 13% HST but applies a provincial rebate; Alberta has no provincial sales tax on electricity. The full 15% HST in Nova Scotia adds approximately 2.5–3¢/kWh to your effective rate — making after-tax bills noticeably higher than the pre-tax rate suggests.
Nova Scotia Power is a subsidiary of Emera Inc., a publicly traded energy holding company (TSX: EMA) headquartered in Halifax. This makes NS Power unique in Canada — every other provincial electricity distributor is either a Crown corporation (SaskPower, Manitoba Hydro, BC Hydro) or a regulated cooperative. NS Power is privately owned and accountable to shareholders.
🏢 What Private Ownership Means for You
NS Power must generate a regulated return for Emera shareholders — a cost built
into your electricity rate. Rates are approved by the UARB but must cover NS
Power's capital costs, operating expenses, and shareholder return. Critics argue
this structural obligation keeps NS rates higher than they would be under a
Crown corporation model.
⚖️ The Regulator: UARB
The Nova Scotia Utility and Review Board (UARB) approves NS Power's rate
applications. Ratepayers can intervene in rate hearings. The UARB has
historically approved most NS Power rate requests, though it has occasionally
reduced requested increases. Rate decisions are publicly available at
uarb.novascotia.ca.
💡 Emera's Renewable Commitment: To NS Power's credit, Emera has invested significantly in renewable energy in Nova Scotia. The Atlantic Loop transmission project (connecting NS to NB and Quebec hydro), wind farm expansions, and the commitment to eliminate coal by 2030 are moving the province toward cleaner — and potentially more stable — electricity generation.
The FAM is Nova Scotia's most distinctive — and most frustrating — electricity pricing feature. It's a quarterly adjustment that reflects NS Power's actual cost of fuel (primarily natural gas, oil, and residual coal) for electricity generation.
NS Power calculates actual fuel costs each quarter and adjusts the energy rate accordingly. If fuel costs exceeded forecast, the FAM adds a surcharge. If costs were lower, it applies a credit.
ℹ️ Actual FAM rates are published quarterly by NS Power at nspower.ca. Values above reflect typical seasonal patterns — individual quarters may vary significantly based on global fuel markets.
☀️ Why This Makes Solar More Valuable in NS: The FAM creates real rate uncertainty — your electricity bill can shift meaningfully every 3 months based on global natural gas and oil markets. Solar panels generate at a fixed cost regardless of fuel markets. Every kWh your panels produce is a kWh that's immune to FAM surcharges — providing both savings and price certainty that NS Power customers don't otherwise have.
Nova Scotia has the highest electricity rates in Atlantic Canada — here's how the four Atlantic provinces compare in 2026:
ℹ️ Why Is NS Higher Than NB? New Brunswick has NB Power, a Crown corporation with nuclear (Point Lepreau) and hydro generation — lower-cost sources than NS Power's heavier reliance on fossil fuels. Newfoundland benefits from Churchill Falls hydro. PEI's higher rate reflects its small isolated grid and heavy import dependence from NB. Nova Scotia's private ownership model and fossil fuel dependency combine to make it Atlantic Canada's most expensive electricity market.
At ~19.1¢/kWh blended, Nova Scotia offers solid solar economics for Atlantic Canada. The province also has more solar irradiance than most residents expect — Halifax receives comparable annual sunshine to Hamburg, Germany, which hosts one of Europe's most active solar markets.
| System Size | Annual Production (Halifax) | Annual Savings at 19.1¢ | Est. System Cost | Simple Payback |
|---|---|---|---|---|
| 3 kW (small home) | ~4,100 kWh/year | ~$783/year | ~$10,000–$13,000 | 13–17 years |
| 5 kW (average home) | ~6,900 kWh/year | ~$1,318/year | ~$15,000–$20,000 | 11–15 years |
| 10 kW (larger home) | ~13,800 kWh/year | ~$2,636/year | ~$25,000–$32,000 | 10–12 years |
| 15 kW (high consumption) | ~20,700 kWh/year | ~$3,954/year | ~$35,000–$45,000 | 9–11 years |
| Off-Grid (rural NS) | Eliminates grid entirely | Full bill + FAM eliminated | ~$25,000–$50,000 | Variable by property |
*Based on Halifax irradiance (~1,380 kWh/kW/year). Assumes 3% annual rate increases including FAM and 0.5%/year panel degradation. All figures before HST savings.
🌊 Rural Nova Scotia Off-Grid Opportunity: Nova Scotia's deeply indented coastline, thousands of islands, and rural interior create many properties where grid connection is expensive or impractical. Remote coastal communities, island properties in Mahone Bay, and rural Cape Breton homesteads are strong candidates for off-grid solar — eliminating not just NS Power bills but also the ongoing FAM uncertainty that makes grid power costs unpredictable.
| Household Type | Monthly Usage | Pre-Tax Bill | After 15% HST | Annual Cost |
|---|---|---|---|---|
| Apartment / 1 bedroom | 300–500 kWh | ~$57–$88 | ~$66–$101 | ~$790–$1,215 |
| Small home / 2 bedroom | 600–900 kWh | ~$103–$150 | ~$119–$172 | ~$1,430–$2,065 |
| Average NS home | ~1,000 kWh | ~$166 | ~$191 | ~$2,290 |
| Larger home / electric heat | 1,500–2,500 kWh | ~$243–$395 | ~$279–$454 | ~$3,350–$5,450 |
| Rural property / well pump | 2,000–3,500 kWh | ~$320–$553 | ~$368–$636 | ~$4,420–$7,630 |
📈 Rate Outlook: NS Power rates have increased approximately 23% since 2020. Ongoing grid modernization, the Atlantic Loop transmission project, renewable energy investment, and coal phase-out costs are expected to drive further increases of 4–6% annually through 2030. The FAM adds additional quarterly volatility on top of base rate increases. By 2030, the blended all-in rate could approach 24–25¢/kWh — further strengthening the solar ROI case.
Nova Scotia receives more sunlight than its Maritime reputation suggests. The chart below shows estimated daily solar production per kW of installed capacity in Halifax. Northern Nova Scotia and Cape Breton produce slightly less; the South Shore receives slightly more.
❄️ Winter Planning Note: Nova Scotia winters reduce solar production by approximately 67% compared to summer. Atlantic weather patterns also bring extended cloudy periods, particularly in November and December. Off-grid systems in Nova Scotia should plan for 5–7 days of battery autonomy and a backup generator or wood stove for the November–February period. Panel tilt angle is particularly important — a steep 60° tilt helps shed snow and captures low winter sun angles more effectively.

NS Power's net metering program allows residential customers to export surplus solar electricity and receive bill credits, reducing the impact of Nova Scotia's high electricity rates.
✅ System Size
Up to 100 kW for residential customers. Adequate for any home installation.
✅ Credit Rate
Credits applied at the retail rate — more favourable than provinces that credit
at wholesale rates only.
✅ Annual True-Up
Unused credits roll forward monthly with an annual settlement. You don't lose
credits at year-end.
ℹ️ FAM and Net Metering: When your solar panels export electricity back to NS Power, your credits are calculated at the current retail rate — which includes the FAM component. This means when the FAM is running high (during periods of elevated fuel costs), your export credits are also worth more. Solar becomes more valuable precisely when NS Power's fuel costs — and your bills — are highest.
| Year | Base Energy Rate | Blended All-In (incl. HST) | Year-over-Year Change |
|---|---|---|---|
| 2020 | ~13.5¢/kWh | ~15.5¢/kWh | — |
| 2021 | ~14.0¢/kWh | ~16.1¢/kWh | +3.9% |
| 2022 | ~14.5¢/kWh | ~16.7¢/kWh | +3.7% |
| 2023 | ~15.5¢/kWh | ~17.8¢/kWh | +6.6% |
| 2024 | ~16.0¢/kWh | ~18.4¢/kWh | +3.4% |
| 2025 | ~16.5¢/kWh | ~19.0¢/kWh | +3.3% |
| 2026 (current) | ~17.0¢/kWh | ~19.1¢/kWh | +0.5% |

📈 23% increase since 2020: NS Power rates have risen at a moderate pace by Canadian standards, but FAM volatility has caused sharp quarterly spikes — particularly during the 2022 natural gas price surge, when some Nova Scotia customers saw quarterly FAM surcharges add 3–4¢/kWh to their bills. The coal phase-out by 2030 should reduce FAM volatility long-term as NS Power's fuel mix shifts to less price-volatile renewable sources.
NS Power's residential rates in 2026 work out to approximately 19.1¢/kWh all-in, including the monthly customer charge (~$10.26), energy charge (~15.5¢/kWh base), Fuel Adjustment Mechanism, and 15% HST. The FAM component fluctuates quarterly based on actual fuel costs, so your effective rate can vary by 1–3¢/kWh from one quarter to the next.
Nova Scotia Power is owned by Emera Inc. (TSX: EMA), a publicly traded energy company headquartered in Halifax. Emera also owns Tampa Electric in Florida and utilities in the Caribbean. NS Power is regulated by the Nova Scotia Utility and Review Board (UARB), which approves rate changes. This private ownership model is unique in Canada — all other major provincial electricity distributors are Crown corporations.
The Fuel Adjustment Mechanism (FAM) is a quarterly rate adjustment that reflects NS Power's actual fuel costs — primarily natural gas and oil used in thermal generation. When global fuel prices rise (as they did sharply in 2022), the FAM adds a surcharge to your bill. When fuel prices fall, it provides a small credit. The FAM can add or subtract 1–5¢/kWh depending on market conditions. Solar generation eliminates your exposure to FAM surcharges on the electricity you self-produce.
Yes — at ~19.1¢/kWh, solar payback periods of 10–13 years are achievable for well-sized systems. Nova Scotia also has better solar irradiance than many residents expect — Halifax receives similar sunshine to Hamburg, Germany. Beyond the financial case, solar eliminates your exposure to NS Power's quarterly FAM volatility, providing energy cost certainty that grid customers don't have. Use our Solar ROI Calculator to model your specific situation.
Yes. NS Power's net metering program covers systems up to 100 kW. Excess electricity exported earns credits at the retail rate (including FAM), which carry forward monthly with an annual settlement. Apply through NS Power's website — approval and meter installation typically takes 8–12 weeks. NS Power-approved installers can handle the application on your behalf.
New Brunswick has NB Power, a Crown corporation with access to nuclear generation (Point Lepreau) and hydro — both low-cost, fuel-price-insensitive sources. NS Power relies more heavily on natural gas and historically coal, which are subject to global fuel market prices. NS Power's private ownership model also requires building shareholder returns into the rate structure. The result: NS rates are approximately 24% higher than NB on a blended basis.
At ~19.1¢/kWh, Nova Scotia ranks fourth-highest among provinces — above Ontario (17.0¢), Saskatchewan (18.6¢), New Brunswick (15.4¢), Newfoundland (15.8¢), BC (10.97–14.08¢), Manitoba (10.6¢), and Quebec (8.3¢); but below PEI (19.7¢) and Alberta (22.9¢).
