 By the end of 2018, hydropower was the largest source of renewable energy, contributing about 40% to the total national electricity capacity.Excluding medium and large-sized hydropower plants, other renewable energy sources accounted for 2.1% of the total capacity of the whole system in mid-2019, but that number is increasing fast.While only two utility-scale solar PV plants were operating at the end of 2018, a feed-in tariff policy deadline led eighty new plants to be connected by 2019.
