In the third quarter, Utilitas produced 95 per cent of energy from renewable fuels
In the third quarter of 2018, Utilitas produced 150,000 MWh of heat and 95,000 MWh of electricity, using renewable fuels in 95% of the production. Wood chips enabled us to restrict the emission of CO2 during the first nine months of 2018.
‘Utilitas wishes to provide comfortable heating services with environmentally friendly solutions,’ said Priit Koit, CEO of the Utilitas Group. In the third quarter, Utilitas produced 225,000 MWh of energy with cogeneration, which amounts to over 90 per cent of the whole production. According to Koit, the district heating network provides the best opportunities for using residual heat from electricity generation – electricity is transferred to the electrical grid and the leftover residual heat is used for heating buildings. ‘Compared to power plants where excess energy would just go to waste, cogeneration plants produce more than twice the amount of energy from the same amount of fuel,’ he explained. Utilitas operates two cogeneration plants and a third one is being constructed in Mustamäe, Tallinn. All cogeneration plants use wood chips, a local renewable fuel, as their main fuel.
In 2018, Utilitas invests a total of 50 million euros into district heating systems. This summer, flue gas condensers were installed in the Jõgeva boiler plant as well as the Spordi and Kristiine boiler plants in Tallinn. Currently, the Mustamäe production complex is being reconstructed – the existing boiler plant will be modernised and a new cogeneration plant using renewable fuels will be constructed. This year, Utilitas modernised and constructed almost 16 kilometres of heat pipeline across Estonia – significant district heating pipelines were renovated in Rapla and Valga, the district heating network in Maardu was renewed, and the largest projects in Tallinn included replacing the heating pipeline at Gonsiori street with a more modern, pre-insulated piping system and modernising the district heating pipeline in the Põhja-Tallinn district.
Utilitas is Estonia’s leading energy group, whose principal activities are the generation of thermal energy and electricity and the provision of district heating services. The aims of Utilitas are clean and efficient generation of heat and electricity and the promotion of economical energy consumption. All district heating systems of Utilitas have been awarded with the Efficient District Heating label. Utilitas provides district heating to 4,741 buildings, including 165,000 households in eight cities all over Estonian: Tallinn, Maardu, Keila, Rapla, Haapsalu, Kärdla, Jõgeva, and Valga.
