A 3.10 Country-specific comments - Sweden Reference scenario Reference Scenario Radial Design Map Interconnectors Reference Scenario Meshed Design Map Sweden’s interconnector in the radial design for the offshore grid design consists of a 700 MW link connecting Sweden to Denmark. This connection is mainly used to export hydro power. The meshed design for the offshore grid is very similar to the radial design for Sweden, but with an additional 700 MW DC link to Denmark. Onshore reinforcement Both the radial and meshed designs require onshore reinforcement in Sweden. A short line on the west coast relieves stress on the system. The estimated cost of this reinforcement is approximately 20 M€(170 million SEK). RES+ commentary The RES+ sensitivity suggested an increase in interconnections from Sweden; however some of these have not been included due to onshore constraints. In the radial design, extra reinforcements on top of those for the reference scenario, are required manage the extra renewables as well as the import from Denmark along two 740 MW DC links. The additional cost of this line is approximately 65 M€(550 million SEK), bringing the total cost of reinforcements to 85 M€. A 1440 MW DC link to Germany is also connected in this design, but this does not require any reinforcements, as it can be connected directly to the South West Link. Page7-57
In the meshed design the connections to Denmark have not been selected, so the only link remaining is the link to Germany. National market studies have shown that such a connection would be beneficial for Sweden in most of the scenarios which have been studied.No internal reinforcements are required in this design.
