Percent curtailmentEstonian Flexibility scenarios the curtailment is 2.8 percent of the yearly windpower production. In the Market Flexibility scenario the curtailment is reducedto zero.Looking at the electricity price for wind power shows the same picture, c.f.Figure 8. The difference between the electricity price at the 900 MW level andthe 1800 MW level is smaller in 2016 than in 2013, implying a better integrationof wind power in 2016, due to Estlink 2. Also more efficient market integrationfacilitates wind integration.3025201510501800 MWLimitedMarketEstonianFlexibilityMarketFlexibility900 MWFigure 7: Wind power curtailment in Estonia in 2016 for the three scenarios and thetwo levels of wind power deployment.26 | Wind Power in Estonia, 13-05-2010

At a 900 MW wind power level, the curtailment is app. 1 percent;while the curtailment is around 15 percent curtailment with 1800 MW windpower capacity in Estonia.4.6 Curtailment in the Baltic StatesBesides the curtailment of wind power production in Estonia, the curtailmentin the Baltic States as a whole has been analysed.In the scenarios for 2013, without Estlink 2, the level of curtailment in Estoniaand the Baltic States as a whole are similar. This situation is changed in 2016with the introduction of Estlink 2, which results in decreased curtailment inEstonia and a larger difference between the curtailment level in Estonia andthe Baltic States as a whole.A symmetric development of wind power has been assumed for all three Balticcountries in the scenarios, i.e. the 900 MW level means 900 MW in Estonia,900 MW in Latvia, and 900 MW in Lithuania. Similar for the 1800 MW level:1800 MW in each of the three countries.27 | Wind Power in Estonia, 13-05-2010
