Last year the undersea power cable between Estonia and Finland, Estlink 2, was not operational due to technical problems during one hour of all the 8,760 hours of the year 2017, which means that reliability reached a record high of 99.8%, informs LETA/BNS.

In 2016 the indicator was 96.5%. In addition, the cable was not operational during 13 hours of the year due to planned maintenance works, the transmission system operator Elering said.
