Hi, we are now Gren.
An absolute pleasure to meet! We are Gren, your new energy company.
Gren – the green energy company. All new, but positively familiar. Our heating & cooling business used to be part of the large energy utility Fortum’s business in the Baltic countries, with a track-record of excellence and pioneering spanning decades.
This is where experience meets future-minded initiatives. This is where we switch off all the excuses, and action on. This is where the future is being energized today in a sustainable and efficient way.
Our ambition is to enable – the customers, businesses, cities and partners alike – to thrive, whatever you might be up to. Because you, your needs and goals are what really matter.
Gren is here to deliver comfort. To people, businesses, municipalities.
And the planet itself.
We are currently developing and improving the new company. We will tell you more about our company’s strategy, values and activities very soon. During the period of ownership change we are following the Code of Conduct of Fortum and Partners Group in every action we do.
Stay tuned and follow the news on our website!
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.
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.
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 landfields. 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.
