Representativity
Representativity
This is the percentage over the total values of a country, which are defined as the synchronously interconnected system plus the areas directly connected (via AC or DC) to the mainland system. Islands that are not connected to the mainland are therefore not considered as part of the "total values of a country".
For the most countries the electricity supply is not analysed in total, but only for those areas participating in parallel operation of the high voltage and extra-high voltage networks of the public supply, this are the undertakings of the public supply (see
UCTE terminology - § 4.1.1
) and - in some countries also - all or part of the industrial power stations, especially their deliveries to the public network.
The areas covered by this analysis represent between 80 and 100 % of the total supply, depending on the countries concerned. Therefore, in some countries differences to other comparable statistics as well as to the statistics published regularly in periodical UCTE reports may result.
