Member States shall take measures to ensure that:

is accurate, reliable and fraud-resistant,
is issued, transferred and cancelled electronically;
the same unit of energy from high-efficiency cogeneration is taken into account only once.
The guarantee of origin referred to in Article 14(10) shall contain at least the following information:
the identity, location, type and capacity (thermal and electrical) of the installation where the energy was produced;
the dates and places of production;
the lower calorific value of the fuel source from which the electricity was produced;
the quantity and the use of the heat generated together with the electricity;
the quantity of electricity from high-efficiency cogeneration in accordance with Annex II that the guarantee represents;
the primary energy savings calculated in accordance with Annex II based on the harmonised efficiency reference values indicated in point (f) of Annex II;
the nominal electric and thermal efficiency of the plant;
whether and to what extent the installation has benefited from investment support;
whether and to what extent the unit of energy has benefited in any other way from a national support scheme, and the type of support scheme;
the date on which the installation became operational; and
