Article 102
Member States may apply a reduced rate to the supply of natural gas, of electricity or of district heating, provided that no risk of distortion of competition thereby arises.
Any Member State intending to apply a reduced rate under the first paragraph must, before doing so, inform the Commission accordingly. The Commission shall decide whether or not there is a risk of distortion of competition. If the Commission has not taken that decision within three months of receipt of the information, no risk of distortion of competition shall be deemed to exist.
