S.L. 545.44 Art. 11Use and cancellation of guarantees of origin. 8 [S.L.    S.L. 545.34. 9

(1) Guarantees of origin shall serve to:

(a) demonstrate to final customers the share or quantity of energy from renewable sources in an energy supplier’s energy mix and in the energy supplied to consumers under contracts marketed with reference to the consumption of energy from renewable sources; and

(b) enable producers of electricity from high‐efficiency cogeneration to demonstrate, upon request, that the electricity sold is produced from high‐efficiency cogeneration:

Provided that for the purpose of paragraph (a), a guarantee of origin shall remain valid for transactions for twelve (12) months after the production of the relevant energy unit.

(2) All guarantees of origin issued in accordance with these HIGH-EFFICIENCY COGENERATION AND OF ENERGY 545.44 FROM RENEWABLE ENERGY SOURCES

regulations, for energy from renewable energy sources which have not been cancelled, shall expire at the latest eighteen (18) months after the production of the energy unit.

(3) The Regulator shall include expired guarantees of origin for energy from renewable energy sources in the calculation of Malta’s residual energy mix.

(4) Where an electricity supplier is required to demonstrate the share or quantity of energy from renewable sources in its energy mix for the purposes of item 5 of the First Schedule to the Electricity Regulations, or where a gas supplier supplying gas from a hydrogen or natural gas network, including gaseous renewable fuels of non‐biological origin and biomethane, is required to demonstrate to final consumers the share or quantity of energy from renewable sources in its energy mix for the purposes of Annex I to Directive (EU) 2024/1788 of the European Parliament and of the Council of 13 June 2024 on common rules for the internal markets for renewable gas, natural gas and hydrogen, amending Directive (EU) 2023/1791 and repealing Directive 2009/73/EC, it shall do so by using guarantees of origin, except:

(b) where no guarantee of origin is issued by the Regulator as provided in regulation 12.

(5) In making their disclosures regarding their energy mix, suppliers may also make use of guarantees of origin to demonstrate the quantity of electricity produced from high-efficiency cogeneration.

(6) Suppliers shall use the information contained in guarantees of origin to demonstrate compliance with the requirements of any Union-wide green label adopted with a view to promoting the use of renewable energy coming from new installations.

(7) For the purposes of disclosure referred to in sub-regulations (4) to (6), energy undertakings shall cancel guarantees of origin at the latest six (6) months after the end of the validity of the guarantee of origin.

(8) The Regulator shall ensure that the guarantees of origin that are cancelled correspond to the relevant network characteristics when a customer consumes gas from a hydrogen or natural gas network, including gaseous renewable fuels of non-biological origin and biomethane, as demonstrated in the commercial offer by the supplier.

(9) The Regulator shall ensure that the data on the residual energy mix is published on an annual basis.
