Overview: The district heating system in Stryi plays a pivotal role in meeting the thermal energy demands of the local community. Operated exclusively by the municipal enterprise Stryiteploenergo, the system provides centralised heating services to an extensive network of consumers, including residential buildings, educational institutions such as schools and preschools, healthcare facilities, and various administrative and organisational structures within the city. Established in 1978, Stryiteploenergo is responsible for the comprehensive management of thermal energy production, distribution, and delivery.

Current DH system: The system currently comprises an extensive network of energy generation facilities. It operates 33 boiler houses equipped with a total of 90 individual boiler units. Collectively, these units represent a total installed thermal capacity of approximately 93.6 MW_th, with an average operational efficiency of 88%. In terms of annual heat production, the network generates approximately 64.88 GWh of thermal energy per year. This energy generation relies on a fuel mix based mainly on fossil fuels (natural gas) and supplemented by biomass sources.

What work will ENABLE DHC do?: The planned upgrading measures are primarily oriented towards transitioning the energy generation portfolio from fossil-based sources to renewable alternatives, in alignment with national and regional decarbonisation objectives.

A key component of the proposed upgrading strategy involves the progressive replacement of natural gas-fired boilers with biomass-based thermal energy units.
