Single audits by year
One row per audit year as the Federal Audit Clearinghouse accepted it. The auditor named is the one observed on that filing; CENTER FOR SUSTAINABLE ENERGY is recorded in SAN DIEGO, California under EIN 330936366, and the Clearinghouse records it as a nonprofit. Each report opens on the Clearinghouse itself; how to search the Federal Audit Clearinghouse explains the rest of the reporting package.

When is the next single audit due?
If CENTER FOR SUSTAINABLE ENERGY is again required to have a single audit for the fiscal year ending Dec 31, 2024, the reporting package is due to the Federal Audit Clearinghouse by Sep 30, 2025 at the latest.
No filing for that fiscal year appears in the Clearinghouse data as of Nov 6, 2026. The data does not show why: an organization below the threshold is not required to file, and a filing can be accepted after the due date.
Whether an audit is required depends on federal awards expended in that year (the single audit threshold). The rule, 2 CFR 200.512(a): the reporting package is due within 30 calendar days after the auditee receives the auditor's report or nine months after the end of the audit period, whichever is earlier; the date above is the nine-month date, moved to Monday when it falls on a weekend. Last verified: 2026-11-15.
Which federal programs did this organization report?
From the most recent accepted report, as listed on its schedule of expenditures of federal awards (SEFA). "Major" is the designation the auditor made under 2 CFR 200.518, not ours.
| ALN | Program | Expended | Major |
|---|---|---|---|
| 81.117 | ENERGY EFFICIENCY AND RENEWABLE ENERGY INFORMATION DISSEMINATION, OUTREACH, TRAINING AND TECHNICAL ANALYSIS/ASSISTANCE | $598,005 | Yes |
| 81.086 | CONSERVATION RESEARCH AND DEVELOPMENT | $148,827 | No |
| 81.086 | CONSERVATION RESEARCH AND DEVELOPMENT | $111,438 | No |
| 81.U01 | EAST TENNESSEE CLEAN FUELS COALITION | $83,581 | No |
What findings did the auditor report?
The reference is the auditor’s; the requirement is the Compliance Supplement category the auditor selected. The finding text itself is not reproduced here; the FAC report linked above carries it in full. What the two severity levels mean: material weakness vs significant deficiency.
The most recent report lists no finding.

How we computed this
Every row comes from the Federal Audit Clearinghouse record named beside it, one report per audit year, with a resubmission superseding the filing it replaces. The auditor is the one named on that filing — it is not a statement about who audits CENTER FOR SUSTAINABLE ENERGY now. Form 990 figures come from the IRS e-filed return named by its object id. This page exists because the organization filed at least two single audits, or one with a finding.
