We serve our customers
We are here to serve our customers – the residents and businesses within our cities– with green and reliable energy solutions that make their lives comfortable and carefree throughout the seasons. We offer modern and professional heating and cooling solutions – separately or in one package. We operate district heating networks, and service individual heat substations for housing associations, individual houses and business customers. We produce electricity that we sell directly to large industrial customers and to the grid.
We produce energy
We produce energy – electricity, heating and cooling from local, renewable and CO2-free resources. We know that waste does not belong in landfills and is a valuable resource that can be turned into energy at the end of products’ life cycle, supporting the circular economy. With care for the environment and the planet, we know how to use natural resources to make your life comfortable and easy. We feel responsible for sharing what we do best and for contributing to societies and the planet’s benefit and well-being.
We are flexible in our offers to serve the needs of our customers best. We are determined to widen our services and to grow even greener together with our customers. If you are interested, just let us know – we will create a tailor-made energy solution for all your needs.
District heating is the safest and most environmentally friendly heating solution for cities and densely populated areas. It secures efficient use of fuels and significantly improves air quality in cities by reducing emissions of fine particles and dust into the air. District heating is a very convenient solution for customers with minimal maintenance costs, low initial investments for connection and with a professional customer service that allows to forget about regular maintenance of heating equipment and fuel supply.
As district heating, district cooling fits perfectly to cities and densely populated areas. Cooling can be produced in a very efficient way (e.g. we can use river’s water as a natural cooling source). The cooled water is distributed via networks to a customers’ cooling unit, where it circulates in the building to provide a comfortable and healthy indoor climate. Connecting a property to the network frees up large amounts of space and helps to achieve carbon neutrality to property owners.
Electricity is an essential part of our daily comfort and is widely used both by households and by different industries. Nowadays, with the wider use of modern technologies, the role of electricity has even increased. Moreover, electricity production plays an important role if we talk about lessening the climate change and the environmental footprint. The more renewables and other CO2-free resources are used for electricity production, the greener and better it is for people, societies and the planet.
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 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.

On Thursday, February 24, Russian troops invaded Ukraine. This completely unjustified and unacceptable Russian war against the sovereignty of Ukraine and its people has engendered both sorrow and compassion in us all.
To support Ukrainians suffering from the brutal and cruel war in Ukraine, Gren – the Northern European green energy company, is donating 30 000 Euro or 100 Euro per each Gren employee to the Red Cross. The donation sum will be equally distributed to the Red Cross organizations in Estonia, Latvia, and Lithuania.
“This is a time when no one can stand indifferent. All our eyes are on Ukraine where millions of innocent people are suffering, dying, were forced to leave their homes and native country. It is inconceivable that something like this could happen in 21st century Europe. We, Gren, colleagues, are in solidarity with European democratic values and support Ukrainian people suffering from the war. We are sure that the Red Cross organizations of Estonia, Latvia and Lithuania will target our support for the purposes where it is most needed and helpful for Ukrainians. We are prepared to continue our support in the future.” says Ilkka Niiranen, the CEO of Gren.

Works of construction of a unique road section, where slag generated in the process of conversion of non-hazardous waste to energy was used, were recently completed in Jurbarkas district. This is the first project of such kind in Lithuania aimed at studying the road in detail and determining the impact that slag has on road operation. The conducted study and the evaluation of the achieved results will allow to decide on further use of slag on Lithuanian roads.
9 000 tons of slag which was generated at the UAB Gren Klaipėda waste-to-energy plant and prepared for use was used in the one-kilometre-long test section. The client of the project was SE Lithuanian Road Administration, the contractor – AB Kauno Tiltai, while the Vilnius Gediminas Technical University (VILNIUS TECH) conducted research in the course of road installation and operation.
The exact location of the experimental section is the regional road of national significance No. 1705 Mikutaičiai I–Vertimai, from 1,8 to 2,8 km, in Jurbarkas district. 5 experimental paving structures were installed in this section. The project has been implemented in two stages. The first stage is the installation of an experimental section and the second stage will be the assessment of the possibility of using slag on the road with the help of installed sensors. The second phase will last till April 2024, but performance results are likely to be available after the first or the second winter.
“The first attempt in Lithuania to use slag generated during the incineration of non-hazardous waste in the construction of roads is an excellent example of the implementation of principles of circular economy. If this experiment proves successful, we would reap comprehensive benefits – waste amounts would be reduced, leaving the environment cleaner, and we would have recycled raw materials generated in Lithuania for expanding road infrastructure. This would be a new step in the transport sector, opening up wider perspectives for the use of environmentally sustainable materials in road construction”, the Minister of Transport Marius Skuodis said.
In September, the Ministry of the Environment approved new requirements for the treatment of ash and slag, which allow using slag remaining after waste incineration in road construction, installation of building foundations, covering layers of disposed waste, closing landfills and installation of temporary roads in them.
The Minister of the Environment Simonas Gentvilas hopes that if the experiment proves successful, it will become possible in the future to use all the secondary raw materials generated in the country, including ash and slag, which will replace granite, which usually is imported into the country. “I invite drivers going through Vertimai village to take note of the road section, which professionals have turned into a road using material that was once our waste. The use of ash and slag creates new value instead of disposing of useful materials in landfills,” says the Minister of the Environment.
Remigijus Lipkevičius, Director of SE Lithuanian Road Administration, says that having obtained positive research results and determined that proper use of slag generated in waste incineration plants in Lithuania is possible, volumes of disposed slag and its disposal costs could decrease, also leading to a decreased need for new aggregates (gravel, crushed stone) extracted in quarries.
According to Vitalijus Žuta, General Director of UAB Gren Lietuva, this is another long-awaited stage of waste utilization. “Since the time when the first waste-to-energy plant started operating in Klaipėda, we have been actively and consistently working to ensure that slag is recognized a useful material, and would be put in use rather than simply disposing of it. During that time, we conducted five long-term studies with various departments of Vilnius Gediminas Technical University and proved that our slag is a reliable and useful material. And this project brought this idea to life,” said Vitalijus Žuta.
There are currently three waste-to-energy plants operating in Lithuania with a total capacity of 615 000 tons of waste per year. In the process of energy recovery, i.e. incineration, about 20% of this amount comes up in the form of slag. Thus, about 120 000 tons of slag are generated in Lithuania per year. Slag forms in the process of incineration of non-hazardous waste at temperatures as high as 1000°C and is a solid, cellular material.
