Idaho National Laboratory Employee Retirement Plan is a defined benefit pension plan sponsored by Battelle Energy Alliance, LLC of Idaho Falls, Idaho. For the plan year ending 30 Sep 2025 it reported 7,309 participants, 806 of them active, and net assets of $1.87B. It is a multiple-employer plan covering the employees of more than one employer.
Net assets came to $255,212 per participant, well above the $87,623 median for defined benefit plans with 5,000 to 24,999 participants and well above the $176,808 median for defined benefit plans in professional, scientific and technical services. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Employer contributions were $0 for the year ($0 per active participant) and benefits paid were $121M. In a defined benefit plan the employer's contribution follows funding rules rather than a match formula, so it can swing widely from year to year.
Schedule C lists 15 service provider organisations paid $5,000 or more, with reported compensation of $7.0M: $963 per participant, well above the same-size median of $232. Administrative expenses charged to the plan were $11.0M. 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 $884M in 2009 to $1.87B in 2024 (up 111%), and participants from 9,547 to 7,309 (down 23%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

What does Battelle Energy Alliance, LLC contribute per participant?
The filing reports $0 in employer contributions for the year, which is $0 per active participant; the median for plans of the same type and size was $9,468 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 $7,037,144 in compensation to service provider organisations, $963 per participant or 0.38% of net assets. The same-size median among plans reporting any Schedule C compensation was $232 per participant. Administrative expenses on Schedule H were $11,038,596. 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.

The sponsor is Battelle Energy Alliance, LLC. Recordkeeping or administration: Battelle Energy Alliance, LLC and Mercer. Investment advisory or management: Pacific Investment Management Co., Jennison Associates, LLC and Sands Capital Management, LLC. Trustee or custodian: Northern Trust Company. The financial statements were audited by Wipfli 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 Oct 2024 to 30 Sep 2025, received by the Department of Labor on 13 Jul 2026. 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.
