EV charging stations in Massachusetts
Massachusetts has no charger registration program today. This prototype shows what the picture would look like if DOS — the Commonwealth's weights & measures agency — registered, inspected, and published every public charger. Backed by real federal and state data; the registration workflow is the proposal.

Real (defensible): All 4,253 station locations, networks, port counts, and connector types come from the NREL Alternative Fuels Data Center API (federal directory, fed by network self-reporting under federal mandate). The 19 EV-designated corridors come from FHWA Alternative Fuel Corridors Round 1-7. The 32 DCR stations come from the MassDCR public ArcGIS feature service.
Demo only (the proposal): Registration status (certified / pending / expired) is illustrative — Massachusetts has no charger registration program today. This is exactly what Dave Rodrigues at the Division of Standards is trying to stand up.
Not shown: 30-day uptime, kWh delivered, and posted prices are notin any open feed today. Each network keeps that to itself. A registration program would require those telemetry feeds via OCPP/OCPI. We intentionally don't fabricate them here.
The Commonwealth's NEVI Phase 1 buildout targets four corridors: Route 2, I-91, I-495, and a portion of I-195. Three vendors were selected by MassDOT in May 2024 to design, permit, build, and operate fast-charging stations along these segments:
Source: Mass.gov, 2024-05-24. Specific station addresses are not yet public — the program is still in design/permit phase. The 2,157 stations flagged on the map above are existing chargers within 1 mile of an FHWA-designated EV corridor — i.e., where Phase 2 network-extension demand is highest.
Owners and operators register every public-facing charging port — including pricing, connector type, and OCPP/OCPI feed.
If a station shorted you, displayed the wrong price, or has been offline, file a complaint. DOS would inspect within 10 days.
Other agencies (MassDOT, MassCEC, EOEEA, EVICC) and the public can pull this dataset. Subscribe via the data warehouse.
The Commonwealth's W&M agency owns this.
Just like gas pumps, propane meters, and grocery scales, EV chargers measure something a consumer pays for. They have to be calibrated, registered, posted with their price, and inspected. NIST Handbook 44 §3.40 already covers them. We'd rather get ahead of the next 10,000 chargers than chase them after the fact.
