European Commission

The European Commission is the executive branch of the European Union, based in Brussels, organized into a college of Commissioners and supporting directorates-general. It holds the EU's right of legislative initiative and enforces EU law across member states. In energy matters the Commission proposes legislation on the internal energy market, security of supply, energy efficiency, and renewable energy, and it oversees how member states transpose and apply these rules. It coordinates infrastructure planning, administers parts of the EU budget directed at energy and climate programs, and works with national regulators and the Agency for the Cooperation of Energy Regulators. Energy policy is shared between the EU and member states under the treaties, so the Commission's role is to propose, coordinate, and enforce rather than to set national energy mixes.
