Large energy companies will be shaken by the European Commission’s (“Commission”) proposals to address the current high market concentration in the gas and electricity markets. Following the Commission’s final report on its energy sector review it is anticipated that the provisions of competition law are likely to be enforced more vigorously in this sector. The areas of particular focus are likely to include enhancing European co-ordination to remove the regulatory gaps which relate to cross-border issues, increasing pricing transparency and dealing with issues of market concentration and barriers to entry. The Commission is also threatening to take measures to unbundle ownership of network and supply activities to ensure greater access to the market.
