Regulators supervise the operation of the electricity market. They have the power to issue opinions on and approve various official documents relating to power grid management (e.g. tariffs, grid development plans). Depending on the competences of the regulator concerned, they may also play a central role in:
- issuing supply licences;
- accrediting renewable energy generation units and combined heat and power facilities;
- issuing and managing green certificates.
