are hosted by, and pass through, a different market node. The annual net export balance
for each market node was calculated by subtracting gross imports from gross exports.
By energy, Belgium and Great Britain are the largest importers in this scenario due to the
assumption that coal is ahead of gas in the merit order and the high proportion of gasfired
generators in their systems. Germany, France, the Netherlands, Norway and Sweden
are large exporters. The region as a whole is exporting approximately 110 TWh towards
its neighbouring countries outside the region, which is about 5% of the region’s annual
demand Figure 4-4.
Luxembourg, Denmark East and Belgium are the largest importers in terms of percentage
of their own demand. The Netherlands is a large exporter in terms of percentage of its
demand.

NSCOGI Reference Scenario for the year 2030 with grid 2020 capacities
Overall the NSCOGI region is a net exporter, with about 110 TWh produced in the NSCOGI
countries for export to meet demands outside the region. This represents an addition 5%
production over the region’s own demand as shown in Figure 4-4. The figure also
presents each country’s import/export position in relation to its own demand. France is by
far the biggest exporter, but in terms of the size of its system, Netherlands is the greatest
exporter. Similarly while Great Britain and Belgium import more energy than any other
country, Denmark East and Luxembourg import the highest percentages of their demand
from neighbouring countries. It should be noted that this does not suggest that they rely
on other countries. For these countries the simulations show that the prices of
neighbouring markets are lower making it more economic to import than to produce
electricity with their more expensive national generators.

While the gross import, gross export and net export balances are provided for each market node,
only the net export balance is provided for the NSCOGI region as a whole.
