How Much Does It Cost to Run a Home Server or NAS in Alberta? (2026)
A network-attached storage box runs 24 hours a day, so even a modest 40 watt draw adds up to 350 kWh a year. Repurposed desktop PCs used as servers can use three times that.
A typical home server or NAS (40 W) costs C$0.009 per hour, or about C$6.47 per month at 24 hours a day in Alberta. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 15 W | C$0.003 | C$0.081 | C$2.42 | C$29.50 |
| Typical 40 W | C$0.009 | C$0.22 | C$6.47 | C$78.66 |
| High 150 W | C$0.034 | C$0.81 | C$24.25 | C$294.99 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 350 kWh per year.
One day of a home server or NAS (0.96 kWh) is the same electricity as
- 5.3km in an electric car
- 9.6hours of TV
- 21hours of a laptop
- 107hours of an LED bulb
In Alberta, with electricity at 22.4¢ per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical home server or nas costs C$0.009 per hour and about C$78.66 per year at 24 hours a day. That is about 60% more than the national average for Canada (C$4.03 per month), because electricity in Alberta costs 22.4¢ per kWh against 14.0¢ nationally. Each C$1.00 of electricity buys roughly 111.4 hours of use.
How to lower the cost of running a home server or NAS
- Enable disk spin-down for drives that are rarely accessed.
- Choose low-power hardware. A purpose-built NAS uses a fraction of an old desktop.
- Consolidate services onto one box rather than running several.
