The EC has accepted RWE ’s commitment to divest its west German gas transmission network, and has closed its investigation into RWE ’s alleged abuses of dominance. The EC ’s investigation was launched in 2006 as a follow-up to its energy sector inquiry. The EC was concerned that RWE , the second-largest energy group in Germany behind E.ON, had denied rivals access to its infrastructure and imposed unfair transmission tariffs. Last year the EC closed an investigation into E.ON’s conduct in the German electricity market after E.ON agreed to divest its extra-high-voltage transmission system and some of its generation capacity. The EC is also investigating the activities of several other European energy groups. It has issued statements of objections to French EDF relating to EDF ’s electricity supply agreements, and to Italian ENI regarding the operation of ENI’s gas transmission network.
