What it sells and charges
Full service (energy and delivery)
| Sector | Customers | Sales (MWh) | Revenue | Average price (cents per kWh) |
|---|---|---|---|---|
| Residential | 1,420,807 | 10,813,601 | $1,784,717,300 | 16.50 |
| Commercial | 172,923 | 14,408,497 | $1,809,326,300 | 12.56 |
| Industrial | 525 | 7,478,805 | $709,508,400 | 9.49 |
| Transportation | 1 | 14,806 | $1,872,900 | 12.65 |
Its average price is 4% above the state average for residential customers (15.83 cents per kWh in MN).
How we got this
$1,784,717,300 residential revenue ÷ 10,813,601,000 kWh residential sales = 16.50 cents per kWh
Average price is revenue divided by sales, for full-service customers only. It averages every rate and every month, so one household's price can differ. State averages count revenue from every kind of service and sales only once, as EIA does.

Reliability
| State | Standard | SAIDI with major events (minutes) | SAIFI with major events | SAIDI without major events (minutes) | SAIFI without major events |
|---|---|---|---|---|---|
| MN | IEEE 1366 | 226.33 | 1.38 | 115.02 | 1.11 |
| ND | IEEE 1366 | 87.59 | 0.55 | 57.04 | 0.46 |
| SD | IEEE 1366 | 160.08 | 0.88 | 58.42 | 0.46 |
SAIDI is the average minutes without power per customer in the year; SAIFI is how many outages the average customer had. Major event days are storms and similar rare days, counted with and without.
