D.3.5 Indigenous Renewable Energy Sources 8) The Government has a strong interest in making use of indigenous renewable energy sources such as wind power, biomass, solar thermal, photovoltaic, hydropower and geothermal energy for electricity, heat production and cooling in the short and medium term. The Ministry with responsibility for Energy Planning, with the consent of the Regulatory Commission and other ministries concerned, will therefore propose to the Cabinet a minimum quota to be achieved by specific years (and in the following years) defining the annual average contribution of electricity from renewable energy sources to the overall public electricity generation delivered to the transmission grid. As a first target, quotas will be set in such a way that at least 5% of the electricity generated in 2013, and at least 15% in 2015, will originate from renewable energy sources. The quota should reach at least 30% by 2020. In the first instance, LUCELEC will be responsible for ensuring that this quota is achieved by generating or purchasing renewable electricity from adequate generation facilities licensed by the ministry in charge for public utilities. The incumbent utility LUCELEC may for such purpose either set up its own renewable energy generation facilities, establish joint ventures, or sub- contract suitable operators and investors.
