National Grid USA Service Company, Inc. of Brooklyn, New York sponsors National Grid USA Co. Incentive Thrift Plan, an ESOP with a 401(k) feature. Its Form 5500 for the plan year ending 31 Dec 2024 shows 24,480 participants (17,603 active) and $6.44B in net assets.
Net assets came to $262,887 per participant, well above the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and well above the $137,166 median for defined contribution plans in utilities. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
The employer contributed $130M during the year, or $7,375 per active participant against a same-size median of $2,424; participants contributed $260M and $19.8M arrived as rollovers and other contributions. Benefits paid out totalled $534M.
Schedule C lists 4 service provider organisations paid $5,000 or more, with reported compensation of $1.2M: $50.47 per participant, below the same-size median of $53.38. Administrative expenses charged to the plan were $1.2M. Schedule C does not capture every cost: fees netted from fund returns and fees the employer pays directly are outside it.
Across the filings on record, net assets went from $1.51B in 2009 to $6.44B in 2024 (up 326%), and participants from 13,231 to 24,480 (up 85%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

Questions and answers
How big is National Grid USA Co. Incentive Thrift Plan?
24,480 participants at the end of the plan year ending 31 Dec 2024, of whom 17,603 were active employees, with net assets of $6,435,482,235. Among defined contribution plans that places it in the 5,000 to 24,999 participants band, which held 2,605 plans in plan year 2024.
What does National Grid USA Service Company, Inc. contribute per participant?
The filing reports $129,829,673 in employer contributions for the year, which is $7,375 per active participant; the median for plans of the same type and size was $2,424 in plan year 2024. Form 5500 reports the total only. It does not state the match formula, and the per-participant figure is an average, not any one person's contribution.
What fees does the plan pay and how do they compare?
Schedule C reports $1,235,494 in compensation to service provider organisations, $50.47 per participant or 0.02% of net assets. The same-size median among plans reporting any Schedule C compensation was $53.38 per participant. Administrative expenses on Schedule H were $1,238,918. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
Who runs the plan?
The sponsor is National Grid USA Service Company, Inc.. Recordkeeping or administration: Vanguard Group Inc.. The financial statements were audited by Deloitte & Touche LLP. Form 5500 also names the plan administrator's signer and other individuals; this site publishes organisations only.
Was the audit opinion unqualified?
The filing reports an unmodified (unqualified) opinion. Unmodified (formerly "unqualified") is the standard clean opinion.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 1 Jan 2024 to 31 Dec 2024, received by the Department of Labor on 14 Oct 2025. Filings are due seven months after the plan year ends, or nine and a half with an extension, so the public record always runs a year or more behind. It contains plan-level totals only: no individual balances, contributions or names of participants exist in the data.
