The European Commission said on April 24 that it has found support 
granted to renewable energy and cogeneration power plants built in 
Latvia between 2007 and 2012 to be in line with EU state aid rules.
The Commission said it concluded that the measure helps Latvia to 
achieve its 2020 energy and climate objectives without unduly distorting
 competition. Latvia notified the existing support scheme to the 
Commission in 2015 for reasons of legal certainty.
Latvia reviewed the support mechanism to ensure that beneficiaries 
are not overcompensated and aid is limited to the minimum necessary to 
achieve the schemes’ objectives. The Commission’s assessment showed that
 the support scheme promoted the deployment of renewable power 
generation and cogeneration without unduly distorting the market, in 
line with the relevant state aid Guidelines.
All final electricity users in Latvia finance the support scheme with
 a levy on electricity consumption. In order to remedy any possible past
 discrimination against foreign green electricity stemming from the 
financing of the support scheme, Latvia has committed to invest in 
projects favouring integration with the European electricity market.
