Our energy production
In Estonia we focus on developing sustainable energy solutions to meet the needs of local communities and to provide comfort for their daily lives.
We serve our customers in Tartu and Pärnu – industrial businesses, housing associations, and individual houses – with clean, reliable and comfortable district heating produced in our biomass combined heat power plants from local and renewable energy. If needed, heat can also be provided by traditional heat only boiler (HOB) plants (biomass and gas-fired) as well as by excess heat from industry (e.g. printing house in Tartu).
District cooling is the latest addition to our energy production in Estonia. We opened the first river-based district cooling plant in the Baltic region in Tartu. In Tartu, district heating and cooling networks are connected via heat pumps, forming an integrated energy system which received international recognition in 2017 when it won the Global District Energy Climate Award in the Expansion category.
Biomass combined heat and power plant in Pärnu
Our biomass combined heat and power plant in Pärnu utilizes local biofuels to provide district heating to approx 890 customers and 19 000 end users. Electricity produced is sold to NordPool and to some large industrial customers.
From the beginning of 2018 new products have been launched to industrial customers nearby the Pärnu plant. We are supplying customers with steam and electricity via a direct line.
Biomass combined heat and power plant in Tartu
Our biomass combined heat and power plant in Tartu utilizes local fuels – woodchips and milled peat, whereby a large part of the peat comes from the company’s own peat deposits. The plant provides district heating to approx 1 900 customers and 72 000 end users in Tartu city.
The Tartu plant is the backbone for Tartu district heating and cooling system that is one of the best and most advanced in Estonia.
Downtown district cooling plant in Pärnu
The most recent district cooling plant was completed in June 2019 in Pärnu.
The plant uses Pärnu river water as a natural cooling source and has the capacity to connect all downtown public buildings to the its network. The first to join our network in Pärnu was Pärnu Keskus shopping center.
Downtown district cooling plant in Tartu
Our environmentally friendly and high efficiency district cooling plant in Tartu, is located by the Emajõgi river and uses the river’s cool water as natural cooling resource.
In 2015, we connected the first customer to the network – the Kvartal shopping center in the heart of Tartu.
Aardla district cooling plant in Tartu
Aardla district cooling plant was completed in June 2017.
The plants initial capacity has been calculated by taking into account the needs of the current main customer’s largest shopping and leisure center in Southern Estonia, Lõunakeskus, and the buildings in its vicinity.
In Latvia we operate in Jelgava and in Daugavpils, where we focus on renewables and on local resources in energy production to support the needs of our customers and local communities while having a positive impact on the environment.
In Jelgava, we are a district heating operator and serve our customers – households, public buildings, businesses – with sustainable, reliable and comfortable district heating produced from local, renewable resources. The balance of renewables in heat production in Jelgava is 92%.
In Daugavpils, we provide heat to the city’s district heating operator, securing around 40 % of the heat energy necessary for the city.
In Riga, the produced heat energy is transferred to the district heating system of the city of Riga.
Our electricity production is mainly from renewables – biomass and wind, and a small portion from natural gas. Electricity is sold at NordPool and to some large industrial customers.
Biomass combined heat and power plant in Jelgava
Our combined heat and power (CHP) plant in Jelgava is using local renewable energy resources, primarily wood chips, to provide district heating (DH) to approximately 16 000 households and 173 B2B customers – schools, public buildings, businesses in Jelgava.
Jelgava CHP plant is the largest biomass CHP plant in Latvia. It has improved the overall efficiency and security of DH and has reduced the CO2 emissions from heat production by 90% compared to 2010.
Now we are working on fuel diversification project that implies adding to the biomass 35% refuse-derived fuel (RDF). That will decrease the amount of waste going to landfills and will have a positive impact on heating and waste management prices for Jelgava residents.
Biomass combined heat and power plant in Riga
Gren Rīga is an energy production company that produces electricity and heat from a local, renewable energy resource – wood chips in a biomass cogeneration plant in the Riga region. The produced heat energy is transferred to the district heating system of the city of Riga.
The cogeneration plant is equipped with an 18 MW HoSt Bio-Energy unit, a high-pressure water pipe boiler and a 3.98 MW steam turbine.
The cogeneration plant has been in business since 2017.
In Lithuania, we operate in Joniškis, Kaunas, Klaipėda and Švenčionys. Our operations focus on sustainable and clean energy solutions from non-hazardous municipal and industrial waste, safe and efficient district heating, and gas allocation and supply.
In Klaipeda and Kaunas we serve our customers – district heating companies of the cities – with heat energy produced from non-hazardous municipal and industrial waste as well as from biofuels. Our waste-to-energy (WtE) combined heat and power (CHP) plants provide a sustainable solution not only for heating but also for the waste management in Lithuania by supporting the waste management system and adding efficiency to it. Waste is used wisely for heat and power production instead of increasing the amount of waste in landfills. Electricity produced from waste is sold to NordPool.
In Joniškis and Švenčionys we serve our customers – residents and businesses – with efficient and comfortable district heating produced from local biofuels and natural gas.
Waste-to-energy combined heat and power plant in Klaipeda
Our waste-to-energy (WtE) combined heat and power (CHP) plant in Klaipeda is the first plant of its kind in Lithuania. It uses non-hazardous municipal and industrial waste as well as biofuels to produce heat for the residents and businesses of Klaipeda city. The plant’s boiler can incinerate up to 255 thousand tons of waste and biofuel annually, the energy efficiency of which is almost 90%.
The modern, clean and effective energy production mode has helped to keep more than 1.5 million tons of waste from being landfilled and polluting the environment. The plant has become a prime example in the energy industry on managing waste and adding efficiency to Lithuania’s waste management system.
Waste-to-energy combined heat and power plant in Kaunas
Joint waste-to-energy (WtE) combined heat and power (CHP) plant developed together with the largest energy company in Lithuania UAB “Ignitis grupė” is the second WtE CHP plant in Lithuania. The plant uses non-hazardous municipal and industrial waste to produce heat for the residents and businesses of Kaunas city.
The plant’s waste fuel boiler is capable to incinerate 250 thousand tons of waste annually and is an essential component in the development of the waste management system in Lithuania. Kaunas CHP plant was built to align with the National Lithuanian Energy Strategy.
