Commercial Energy Management in the South Coast
South Coast is Eversource territory inside ISO-NE — SEMA load zone. Eversource delivers the power and maintains the wires whoever supplies it, so competitive supply carries no reliability consequence — only a lower price.
How Energy Buying Works in South Coast
New Bedford is the highest-value fishing port in the United States, and its commercial load reflects that: seafood processing and cold storage running continuous refrigeration, with sharp seasonal swings around the scallop and groundfish seasons. It has also become the staging harbour for Northeast offshore wind, adding industrial and port load. Eversource serves the South Coast in the SEMA zone. Continuous refrigeration against seasonal throughput is the classic case for block-and-index — a fixed block sized to the freezer baseload, with seasonal volume left to index rather than hedged at a premium.
Massachusetts opened to competition in 1998, but the terms are set territory by territory, not statewide. Eversource's distribution rates, its default supply price and its rate schedules are all set independently of the other utilities in Massachusetts — which is why an offer that is genuinely competitive in one part of the state can be mediocre here. Everything on this page is scoped to Eversource specifically.
Eversource Commercial Rates
Which schedule you are on sets the shape of the bill before a single kilowatt-hour is priced.
| Schedule | Typically covers |
|---|---|
| G-1 — General Service | small commercial accounts |
| G-2 — General Service Demand | demand-metered commercial accounts |
| G-3 — Large General Service | large commercial and industrial load |
Schedule names, demand thresholds and eligibility rules change with each rate case, and the schedule an account was originally placed on is frequently no longer the one that fits it. We verify yours against the actual bill rather than assuming — that check is free, and it is where a meaningful share of the savings on this page comes from.
