Massachusetts Electric Co
Massachusetts Electric Co is investor owned serving 526,437 residential customers in Massachusetts, at an average residential price of 33.60¢ per kilowatt-hour.
That price is derived, and it is annual. It is total residential revenue divided by total residential sales in EIA’s 2024 survey — not a tariff, and not this month’s rate. For what a kilowatt-hour costs in Massachusetts right now, see the state page, currently 29.61¢.
What it reported, by service
| Service | Residential customers | Residential | Commercial |
|---|---|---|---|
| Bundled | 526,437 | 33.60¢ | 23.03¢ |
| Delivery | 683,676 | 16.30¢ | 10.10¢ |
A utility can file bundled service and delivery-only service separately. A delivery-only price excludes the energy itself, so the two are not comparable and are not ranked against each other.
How often the power goes out
| Minutes without power per customer, 2024 | 133.7 minutes (SAIDI, including major event days) |
|---|---|
| Interruptions per customer | 1.00 (SAIFI) |
| Excluding major event days | 90.7 minutes the figure utilities are benchmarked on |
| Reported under | IEEE standard |
The headline figure includes major event days, because a customer who lost power for three days in a storm lost power for three days. See how this compares nationally.
