Estonian Competition Authority
The Competition Authority has analyzed reliability of electrical interconnections EstLink 1 and EstLink 2 between Estonia and Finland. The Competition Authority has reached the conclusion that the current legislation does not sufficiently regulate operation of electrical interconnections. It is important to provide for respective quality requirements with regard to EstLink 1 and 2 cables: for instance, the maximum allowed annual period of downtime outage shall be set out.
The analysis was aimed at finding out the reasons of EstLink 1 and 2 downtime outage and at giving the answer to the question, whether the downtime outage could have been avoided. As the result of the proceedings it was discovered that just like in case of all other technical devices, EstLink 1 and 2 interconnections cannot provide 100% guarantee of reliable operation. At the same time, better organization of work can provide for higher levels of reliability.
EstLink 1 and 2 interconnections are very important for Estonia, as well as Latvia and Lithuania – the price of electricity for consumers directly depends on operation of the interconnections. Therefore setting certain quality requirements (and thus the goals with regard to reliability) will be in the best interests of electricity consumers, producers and traders. Consumers cover EstLink 1 and 2 expenses by paying network fees and they are interested in bringing reliability of the interconnections to the maximum level possible.
