If everything lands in spring, data preparation and audit compete for the same weeks.

What utilities ask before certificate season

Who may audit CHP Act settlements?

German Public Accountants, audit firms, cooperative audit associations, sworn auditors and their firms.

Must the concession fee settlement with the municipality be audited?

Only where the concession contract provides for it. The KAV proof is separate: with it, the supplier proves to the grid operator, by audit certificate, that lower concession fees apply.

Which certificates are mandatory for grid operators?

The certificate on the combined EEG and CHP final statement is mandatory, submitted to the upstream TSO by 31 May (section 55(1) sent. 1 EnFG). Other final statements and notifications are certified by an auditor at the grid operator’s request (section 55(1) sent. 2 EnFG).

When is the section 19 StromNEV statement due?

Grid operators submit the annual statement of revenues lost through individual grid charges to the TSO by 31 July of the following year. The IDW audit guidance for it is IDW PH 9.970.30.

Does our CHP plant need a certificate?

Yes, above 2 MW of electrical CHP capacity, as long as it receives surcharge payments: the statement for the previous year goes audited to BAFA and the grid operator by 31 March. Up to 2 MW the data are due by 31 March without an audit (sections 15(2), (3) and 30 KWKG).

Do you also audit the utility’s annual accounts?

Yes. For grid operators and vertically integrated utilities the audit of the annual accounts also covers the unbundling accounts under section 6b(3) EnWG. If the municipality holds a majority, it can also request the audit under section 53 HGrG.

What does the certificate audit cost?

The fee depends on scope and effort. We give you the range after the intro call, and the fee is set out in writing in the engagement letter.
