Eastern MA Eversource Supply Rates: Feb–Jul 2026 Historical Comparison

For a Eastern MA Eversource residential account, the published supply figures provide a dated historical comparison. Eversource listed a fixed residential supply rate of $0.15629 per kWh from February 1 through July 31, 2026. Its monthly variable rates for those months were $0.21618, $0.15208, $0.13302, $0.12538, $0.13062, and $0.16217 per kWh. These are supply charges only; delivery, taxes, and other bill lines still apply. Eversource’s Massachusetts supply-rate page lists the period. Because July 31 has passed, use these figures to audit an old bill or understand the rate structure; do not use them as a current switching quote.

Reproduce the six-month comparison

Assume, for comparison only, 500 kWh in each month. Fixed supply is 500 × $0.15629 × 6 = $468.87. The six variable rates total $0.91945, so variable supply is 500 × $0.91945 = $459.73. The variable figures are lower by $9.14 in this constructed period. That result is arithmetic on observed rates, not a forecast: your usage can change and the variable rate can rise sharply in a later month.

Eversource says the fixed rate changes twice each year, on February 1 and August 1. The monthly variable rate changes monthly and reflects the cost of purchased electricity. The page says a customer may choose the monthly variable rate only once, so read the current account terms before changing.

Keep delivery out of the supply comparison

Eversource’s Massachusetts delivery page lists a $10 monthly customer charge for the April 1–July 31, 2026 residential classifications, plus separate per-kWh delivery components. The delivery tariff is not included in the supply numbers above. Do not multiply a supply rate by your total bill and call it the final bill.

Use the effective-date range to audit a February–July bill, then open Eversource’s current table before making a supply-plan decision. Save the rate period because these figures are historical Massachusetts evidence, not a current offer.
