Lithuania has a well-developed district heating system, with 357 networks as of 2015. The share of district heating in the overall heating sector remained fairly constant through previous years; on average, around 56% throughout the country and 76% in cities. The total installed capacity of district heating slightly increased to 10,1 TWh in 2015.
As seen in the graph below, district heating supplied the majority (56%) of heat demand in 2015. This was followed by renewables contributing with 32% of heat supply. Also within district heating, a large proportion is now supplied through renewable energy. In 2015 local biomass accounted for almost two thirds of the fuel used for producing heat. The estimated share of renewable energy sources in 2020 should increase to 80% provided that large-scale biomass and municipal waste CHP projects will be implemented.
In 2015, 59% of the national electricity and 43% of district heating was supplied by CHP. Around 31% of the total fuel for CHP was covered by renewables. It was the authorities’ decision that 2015 was the last year for buying up “quota” electricity above the market prices from fossil fuel powered combined heat and power plants. At the end of the 2015, Vilnius CHP-3 was shut down; other large CHP plants continue operating on a fragmentary basis only.
