Ofgem announced the first of two consultations on the Energy Company Obligation (ECO3) methodologies for calculating electricity and gas supply volumes on Friday 11 October. This consultation focuses on changes to the supply volume methodologies, with Ofgem proposing that for electricity, suppliers should provide the total kWh delivered to customers on profile classes 1 and 2, and customers on profile class 00 with consumption component class 36. Gas volumes should be consistent with the annual quantity values set out in the UNC. Responses are requested by 8 November. The second consultation will concern improving consumer protection, and will be published after the government has published the response to its own consultation on the subject.
