Electricity more than 99.99% of the time
In 2015, electricity was available to the Danes more than 99.99% of the time, which means that citizens and companies in Denmark continue to benefit from a very high level of security of electricity supply.
This is documented in Energinet.dk’s electricity security of supply report 2016. Electricity consumers experienced 22 minutes of outage on average per consumer in 2015. A low figure testifying to the high security of supply in the overall electricity system.
“I’m proud that, again in 2015, Denmark was able to ensure a very high level of security of supply at the same time as having a wind power share of 42%. That’s quite an achievement,” says Søren Dupont Kristensen, Vice President, System Development and Electricity Market, Energinet.dk.
High level requires new initiatives
Forecasts in Energinet.dk’s electricity security of supply report 2016 show, however, that initiatives must be launched continuously in order to support Energinet.dk’s ability to keep the security of supply in Denmark at the same high level.
The risk of a lack of power in Eastern Denmark will exceed Energinet.dk’s objective in the coming years. One of the reasons for this is the strategic reserve we expected to introduce from the beginning of 2016, but which got the thumbs down from the EU. We are still hoping to be able to establish a strategic reserve in the course of 2017.
In special situations with breakdowns at power stations, calm weather and no possibility of importing sufficient electricity, there is an increased risk of power cuts. With a new 400 MW international connection to Germany via Kriegers Flak offshore wind farm, we expect to improve the situation.
“We’ve launched a number of initiatives to reduce the risk of power cuts for consumers, including closer coordination as to when plants are shut down for maintenance, closer coordination with neighbouring electricity systems and continued efforts to procure a strategic reserve in 2017 and 2018,” says Søren Dupont Kristensen, Vice President, System Development and Electricity Market, Energinet.dk.
Increased international cooperation
The cooperation on security of electricity supply has taken large strides in 2015, and is increasingly becoming a cross-border task. A number of network codes are on the way from the EU, and they will have a major impact on the future work.
ENTSO-E, the European Network of Transmission System Operators for Electricity, develops common procedures for analysing generation adequacy. At Nordic level, cooperation has been strengthened with a joint office in Copenhagen focusing on operational coordination.
