BNetzA: Security of Electricity and Gas Supply Remained High in 2010

The security of the electricity and gas supply remained high in Germany in 2010, the Federal Network Agency (BNetzA) reported.

System interruptions in the electricity sector measured according to the System Average Interruption Duration Index (SAIDI) rose slightly from 14.63 minutes in 2009 to 14.90 minutes in 2010. In the gas sector system interruptions fell from 1.88 minutes to 1.25 minutes.

With respect to the electricity grids, BNetzA’s president Matthias Kurth pointed out that the expansion of the grids had to keep pace with the expansion of renewable energy sources in order to maintain the internationally low level of system interruptions. The agency also remarked that network reliability (Netzzuverlässigkeit) would be introduced as quality element pursuant to the Incentive Regulation Ordinance (ARegV) for the electricity sector as of 1 January 2012.

The figures presented by BNetzA show that Germany has so far been able to integrate the rising amount of renewable energy into its grids despite the boom in solar power in 2010. If, however, this will be the case after Germany reversed its energy policy following the nuclear catastrophe in Fukushima, Japan, in March remains to be seen. In June/July the German parliament (Bundestag) and the Federal Council (Bundesrat) adopted a legislative package that provides for a withdrawal from nuclear energy until 2022 and an expansion of renewable energy.

In October the European Network of Transmission System Operators for Electricity (ENTSO-E) voiced its concern about generation adequacy margins for the coming winter, resulting, among others, from the immediate shutdown of eight German nuclear power plants under the the German energy package.
