Technical indicators

Description: 20161) 2017 Change IVQ 2016 IVQ 2017 Change
SAIDI planned interruptions and unplanned interruptions, including catastrophic ones (HV, MV) [min] 241.76 618.71 155.92% 46.35 312.18 573.53%
SAIFI planned interruptions and unplanned interruptions, including catastrophic ones (HV, MV) [pcs.] 3.72 4.31 15.86% 0.82 1.55 89.02%

1) The change in the SAIDI and SAIFI indices presented in the reporting documents for 2016 results from the verification by the President of the Energy Regulatory Office of the algorithm for aggregation of interruptions in the power supply to SN/nn substations located in the IT tool for calculating reliability indices in Enea Operator Sp. z o.o.

In 2017, in the operation area of Enea Operator several extensive failures of the power network took place. They were caused by extremely unfavourable weather conditions. These events resulted in a significant deterioration of reliability of electricity supply (SAIDI and SAIFI) in relation to 2016.

Taking into account 2017, despite ensuring proper exploitation of the network assets, it was not possible to avoid failures caused by extremely unfavourable weather conditions and other emergency situations. There is a risk that similar situations will occur in subsequent years.
