Market context
Local grid, utilities, climate and procurement.
Boston is supplied by Eversource Energy (Boston metro and most of eastern Massachusetts) and National Grid (south shore and parts of MetroWest), interconnected through ISO New England. The grid runs 13.8/23 kV at MV and 115/345 kV at transmission, with the New York-New England 1,400 MW Cross-Sound Cable and the proposed Twin States Clean Energy Link (1,200 MW HVDC from Quebec) reshaping import flows. Massachusetts' 2050 net-zero target and the Vineyard Wind / Mayflower Wind offshore programmes (3.6 GW combined) drive demand for offshore-substation step-up transformers (66 kV collector → 220 kV export), grid-tie reactors and battery-storage interface units. Specifications follow IEEE C57.12.00 with Eversource Engineering Specification 152 (pad-mount), Northeast cold-weather rating (−40 °C cold start), copper windings and ester-fluid mandatory for vault and indoor units. Procurement is shaped by Logan Airport's electrified ground fleet, the Seaport District biotech expansion and the South Coast Rail extension. Tender hints: Eversource uses Ariba SLP; National Grid maintains a separate QPL inherited from Niagara Mohawk.
