In 2020, the transmission reliability rate on the main grid reached a record-setting 99.99995 per cent. This figure describes the amount of energy transmitted by the main grid for consumption as a proportion of the amount of energy that was available for transmission. Only 37 MWh of electrical energy was not transferred for consumption as a result of disturbances on Fingrid’s network. In addition, the quality of the frequency in the Nordic synchronisation area was much better last year than in the preceding years.
