A retiree in Cape Breton pays 4.5× more per kWh than a data center pays Hydro-Québec for the same electricity.
🔥 Nova Scotia Power: A Case Study
8.1% residential rate hike proposed for 2026-2027
NS Power is asking the Energy Board for 3.8% in 2026 and 4.1% in 2027 — compounding to 8.1%. This would generate $180 million in additional revenue.
Meanwhile, large industrial customers would see rate decreases of nearly 10% over the same period. Residential customers pay more. Big business pays less. Same grid.
The Emera problem
NS Power is a subsidiary of Emera Inc. (TSX: EMA), which reported $849 million in net income for 2024 and announced a $20 billion capital spending plan — 80% going to Florida.
NS Power represents only 19% of Emera's income, but demands a guaranteed 9% return on equity from Nova Scotia ratepayers.
Parent company profits rose 11% in Q3 2025. NS Power profits dropped 50% — partly due to a data breach they caused.
The data breach they want you to pay for
In April 2025, NS Power suffered a ransomware attack exposing 280,000+ customers' personal data — including social insurance numbers. Customers received estimated bills double or triple their actual usage. The company says breach costs aren't in the rate application.
Premier Houston called them "out of touch" for requesting rate hikes in the aftermath. All three parties oppose the increase.

The Rate Gap: Who Pays What
Large industrial customers pay less per kWh than you. There are legitimate reasons for this — they take power at high voltage, use it at a flat 24/7 load, and cost less to serve per unit. Volume discounts exist in every industry.
The question isn't whether industrial rates should be lower. It's whether the gap has become so large that residential ratepayers are subsidizing the profits of the most valuable companies on Earth. When grid upgrades are needed to serve new industrial load, those capital costs get spread across all ratepayers. The discount was set when "data center" wasn't in anyone's vocabulary.

Residential rates from published utility tariffs (2025-2026). Industrial rates from regulatory filings. Data center rates from utility marketing materials. "—" = no published rate. QC arrows show 2025 rate increase: residential got 3%, Rate L got 1.7%.
The Data Center Surge
AI is driving an unprecedented explosion in electricity demand. Data centers need massive, constant power — and they're competing with you for it.
The scale
37 data center projects are queued in Alberta, requesting 19 GW — double the province's entire current generation. One large data center uses as much power as the city of Edmonton. In Ontario, data centers will be 13% of new demand by 2035. Hydro-Québec lists them as the largest new demand in their 10-year plan.
100% waste heat
Every watt entering a data center exits as heat, vented into the atmosphere. A 100 MW facility generates as much heat as 30,000 space heaters running 24/7 — while families across the street can't afford their heating bill. A single ChatGPT query uses 10× the electricity of a Google search.
You pay for their infrastructure
When a data center connects to a legacy hydro grid, it consumes the surplus that kept your rates low. New generation and transmission capacity must be built — and those capital costs get spread across all ratepayers. The Canadian Climate Institute warns this can push residential bills higher, especially in provinces like QC and BC.
The fair price question
If tech companies want Canada's clean, cheap power to train AI models, they should pay a rate that reflects the true marginal cost of serving that load — including the infrastructure expansion it requires.
The current system prices it at the embedded cost of hydro built by Canadian taxpayers decades ago. That's not a cost-of-service argument. It's a political choice.
Rate Increases Over Time
What You Can Do
1. Report your bill. Every report strengthens the dataset. The more we have, the harder it is to ignore. 2. Email your MLA. Data-backed letters from real constituents get attention. We make it easy. 3. Share this page. Energy costs are invisible until people compare. 4. Demand transparency. Why do residential rates rise 8% while industrial rates drop 10%?
Canadians are paying too much for power. WattRot is a free, anonymous tool that lets you report your electricity bill and see how it compares across providers, provinces, and communities. Together, we make the data visible and hold utilities accountable.
There is no public dataset tracking what Canadian families actually pay for electricity — just tariff sheets and provincial averages.
WattRot is building that dataset, one bill at a time. Every report makes the picture clearer. Enough data and patterns emerge — which providers charge the most, which communities are hardest hit, and whether the rates you pay are fair.
Your bill is not just a number. It's evidence.
tips_and_updates Every old bill helps
The more history we collect, the stronger the dataset. Past bills are just as valuable as today's. Most utilities keep 24 months of billing data in your online portal — and WattRot accepts bills from any date. Dig up those old bills. No bill is too old. The more detailed (kWh, dollar amount, month) the better.
