NSTAR ELECTRIC COMPANY
NSTAR ELECTRIC COMPANY is a Public Limited Company registered in United States under 041278810, and its current status with Massachusetts Secretary of the Commonwealth is active. The company was incorporated on 8 January 1886 and lists its registered address as United States. 1 shareholder is on record for NSTAR ELECTRIC COMPANY, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Massachusetts Secretary of the Commonwealth and was last updated on 6 October 2026.

Shareholders
1
One shareholder is currently on record for NSTAR ELECTRIC COMPANY, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is SEI Tax Exempt Tr-SEI Tax-Advantaged Income Fund, holding 7.1% — the largest recorded stake.
Because the shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Executive Vp, General Counsel & Director of NSTAR ELECTRIC COMPANY currently on record is Gregory B. Butler Esq.; five officers are currently on record for NSTAR ELECTRIC COMPANY, filed with Massachusetts Secretary of the Commonwealth.
The register reports 24 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at NSTAR ELECTRIC COMPANY sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
NSTAR ELECTRIC COMPANY sits 1 level below its ultimate parent, Eversource Energy, registered in United States. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to Eversource Energy is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by NSTAR ELECTRIC COMPANY's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 1 subsidiary spans United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
