According to the European Network of Transmission System Operators for Electricity’s (ENTSO-E) updated 10-year network development plan, Europe’s networks require an investment of 104 billion euros in projects of pan -European significance by 2020.
The investments are to cover the over 100 transmission projects of pan-European significance that have been identified to address “network bottlenecks” as a result of market integration and generation connection. 80% of the bottlenecks are related to renewable energy integration, either connecting the renewable sources with load centres or the direct connection of renewables.
This plan is based on an increase in generation capacity of about 250 GW in the next 10 years, the majority of which particularly in wind and solar renewables.
Market studies suggest that by 2020 Italy, the U.K., Poland and Baltic states remain major importing countries. France and Scandinavia are the larger exporters, as is the case today, although exchanged volumes are higher. Germany, Spain and Portugal experience high exchange volumes but for both imports and exports, which results in an overall balance. As a result larger, more volatile power flows, can be expected over larger distance across Europe, mostly north to south from Scandinavia to Italy, between mainland Europe and the Iberian Peninsula, Ireland and U.K. or east to south and west in the Balkan Peninsula. Consequently investment is needed to avoid present congestion worsening and new congestion appearing.
The plan is significant for the TSO’s. The plan is also in line with the European 20-20-20 objectives.
