National Grid plc
National Grid plc (NYSE: NGG; London, UK; ~£18B revenue) is the operator of major gas and electricity distribution networks in the United Kingdom and the northeastern United States. National Grid's US gas distribution subsidiary — National Grid USA, primarily serving Massachusetts, Rhode Island, and New York — operates multiple LNG peak-shaving facilities in Massachusetts that are critical to winter natural gas supply. Massachusetts LNG peak-shaving plants operated by National Grid represent some of the largest LNG storage and vaporization assets in the US Northeast. National Grid Massachusetts stores approximately 10 billion cubic feet equivalent of LNG in its peak-shaving facilities, used to meet extreme cold-weather demand spikes when Algonquin and Tennessee Gas pipeline imports are insufficient. National Grid also operates LNG in New York (Long Island).

Eversource Energy LNG Peak-Shaving Facility (Connecticut) →
USConnecticut · storage
Eversource Energy (Hartford, CT; formerly Northeast Utilities) operates LNG peak-shaving facilities in Connecticut for winter supplemental gas supply. Eversource sold its Everett LNG import terminal to New Fortress Energy in 2020 but retains utility-owned peak-shaving LNG storage assets in Connecticut and Massachusetts. Connecticut LNG peak-shaving is critical backup when Iroquois Gas Transmission (the main CT pipeline) faces constraints. Note: this facility placeholder represents Eversource LNG infrastructure; Eversource has no current supply_companies entry — mapped to National Grid for data model consistency pending dedicated company row.

National Grid LNG Facility (Acushnet, MA) →
USMassachusetts · storage
National Grid LNG peak-shaving storage and vaporization facility in Acushnet (Bristol County), Massachusetts. Serves southeastern Massachusetts winter gas supply. One of several National Grid LNG facilities in Massachusetts that collectively provide the backup supply cushion for the region's gas distribution network during winter demand peaks.

National Grid LNG Peak-Shaving Facility (Boston area, MA) →
USMassachusetts · storage
National Grid USA operates multiple LNG peak-shaving facilities in the greater Boston, Massachusetts area used for winter gas supply during peak demand events. These facilities liquefy natural gas during summer off-peak periods and vaporize it during winter polar vortex events when Algonquin Gas Transmission and Tennessee Gas Pipeline imports are insufficient. National Grid Massachusetts LNG storage accounts for a significant fraction of New England peak gas supply capability.

National Grid's Massachusetts and Rhode Island gas distribution system is simultaneously the natural gas heating utility for millions of New England residents AND the operator of LNG peak-shaving facilities that serve as the region's last-resort gas supply buffer when interstate pipelines are maxed out during polar vortex events. National Grid's ~10 Bcf-e of LNG peak-shaving capacity in Massachusetts is what prevents Boston from running out of heating gas during January cold snaps when the Algonquin Gas Transmission and Tennessee Gas pipelines are operating at full capacity. The LNG stored in National Grid's Everett-area and South Weymouth tanks was liquefied from the same gas pipeline system it's used to supplement — a strategic buffer allowing the region to weather multi-week cold periods without interstate pipeline capacity additions. National Grid simultaneously operates the pipes that deliver gas for home heating AND the LNG storage that extends pipeline capacity AND (in its New York operations) the electric distribution wires that power the gas-fired generators that keep the lights on when wind and solar are insufficient. A British privatized utility is the de facto energy security operator for the US Northeast during winter weather events.

National Grid emerged from the 1989 UK Electricity Act — Margaret Thatcher's privatization of the Central Electricity Generating Board (CEGB), the state monopoly that had operated the UK's power system since 1926. The CEGB was itself a 1926 rationalization of the chaotic patchwork of local UK electricity systems: 600+ local authorities and private companies were operating incompatible systems that prevented national interconnection. The 1926 Electricity (Supply) Act created the National Grid Company to build and operate a unified national transmission grid. The CEGB took over in 1948 (nationalization) and ran the UK power system until Thatcher privatized it in 1990. National Grid the plc is the privatized successor of the government entity that built the UK grid in the 1930s. National Grid expanded internationally by acquiring New England Electric System in 2000 and KeySpan Energy (New York gas) in 2007 — becoming the primary gas and electric utility for the most densely populated region of the US Northeast. A Thatcherite privatization of a 1926 British nationalization owns the gas pipes and electric wires serving Boston, Providence, and Long Island.
