Biogas CHP Plant

evaluation of conformity

The installations must comply with the legal provisions of the Directive and map their capability requirements on the basis of an expert report.

Compliance with these requirements must be checked annually by an accredited environmental verifier.


An Biogas CHP plant assessment includes an on-site visit where the installation is inspected by the environmental verifier and an off-site evaluation of the annual feed-in quantities from the comparison of the meter readings and billing documents of the network operators.
