Electricity disclosure regulations

All electricity supply companies are forced by the European electricity directive (2009/72/EC) to disclose information regarding their fuel-mix to consumers. Some countries have more strict disclosure rules than others, however most countries agree the electricity tracking via the EECS-GO system is one of the best methods to ensure proper fuel-mix disclosure and the elimination of green attribute double counting Europe-wide. Some larger electricity producers have gone so far as to issue GOs for all of their electricity production sources, non-renewable electricity included, as a means of proper accounting and responsible information disclosure.

All organizations that use GOs to modify their consumed fuel-mix do so by retaining ownership of the attributes for that specific production source.  In terms of carbon-dioxide emissions, this makes the electricity grid’s average emissions per kWh much dirtier for those that do not cancel GOs for their electricity purchase.  This is because the consumer that owns the electricity attributes, including its low-carbon attributes, owns them at the expense of these low-carbon attributes becoming a public commodity and part of the grid average.  This increased grid emission factor is well known by the name, ‘residual mix’.  The residual mix is counted yearly by an European E-track project, ‘Reliable Disclosure Systems for Europe’ (RE-DISS) as well as the ‘European Platform for Electricity Disclosure’ (EPED)

While electricity supply companies are all forced to provide disclosure information to their consumers only some nations force that this disclosure information include residual mix calculations. Some not for profit organizations encourage the use of a residual mix in both national supplier disclosure information as well as personal disclosure (carbon accounting).
