Benchmarking of continuity of supply

At the end of October 2008 the Danish Energy Regulator Authority (DERA) made their first benchmark of continuity of supply in Denmark. The benchmark includes all Danish distributions system operators (DSOs) and regional transmission system operators (RTSOs) operating networks at voltage levels from and including low voltage distribution networks (230/400 V) and up to and including the 150 kV network. The benchmark is made in the light of the number of weighted customer interruptions in each DSO or RTSO area. For DSOs operation of low voltage and 6–25 kV distribution networks an extra benchmark is made in the light of the accumulated number of interruptions each customer is exposed to each year (worst served customers).
