Commercial Energy Management in the Merrimack Valley
Merrimack Valley is National Grid territory inside ISO-NE — NEMA load zone. National Grid 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 Merrimack Valley
Lowell's commercial building stock is overwhelmingly converted nineteenth-century mill space, and that has direct energy consequences: single-glazed envelopes, retrofitted HVAC serving volumes it was not sized for, and master meters carved up among tenants long after the original service was installed. National Grid serves the valley inside the NEMA zone. The most productive work here is rarely the supply contract — it is metering and cost allocation, sorting out which tenant is actually driving demand in a building where the landlord has been apportioning by square footage since the conversion.
Massachusetts opened to competition in 1998, but the terms are set territory by territory, not statewide. National Grid'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 National Grid specifically.
National Grid 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 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.
