Open district heat
Does your company or property generate surplus heat? When you sell your surplus heat to us, you will take part in emission-free heating in Helsinki, receive a predictable income flow and contribute to the promotion of a flexible energy economy.
Heat a piece of Helsinki
By utilizing heat that would otherwise go to waste, we increase the amount of recovered heat fed into Helsinki's district heating network. Your company or property can become part of an energy system that increasingly operates like a flexible community.
A study commissioned by us on the sustainability of corporate energy choices found that Finns consider recycling, the use of renewable materials, and the reduction of environmental impacts to be the most important indicators of responsible business practices.
Although the idea of recycling heat energy is still relatively new to the general public, it makes it possible to utilize energy that would otherwise go unused.
We already heat nearly 75,000 homes in Helsinki with recovered heat. How many homes could your company's surplus heat warm?
Efficient recycling of energy
Our energy system enables efficient recycling of heat in Helsinki. We are, indeed, a forerunner in the utilisation of waste heat.
Almost 10% of district heat in Helsinki is produced by utilising the heat of purified waste water and with district cooling. We recycle, process and reuse the surplus heat of our customers in our Esplanade and Katri Vala heating and cooling plants.
We want to increase efficient recycling of energy and expand it further, and to purchase surplus heat from actors who use our district heat, such as production plants, data centers, properties, companies and residential buildings. By utilising surplus heat, we can together reduce the use of other energy sources.
We are constantly seeking new areas where we can develop energy-efficient solutions.

Frequently asked questions about the sale of heat to the district heating network
An open, i.e. two-way, district heating network means a heating network where the customers can buy heat and sell the heat they produce to the energy company.
Heat can be sold, for example, by industrial plants, service and retail operators, property owners and heat producers. We buy heat from sites, which produce heat that is suitable for utilisation as such in the district heating network.
The surplus heat of your property or company is usable energy that can be utilised in heating elsewhere.
In order to sell heat to the network, you need a district heat connection. Selling heat from an existing district heat connection requires modification work on the customer’s connection and equipment. The best situation is when the customer can offer suitable heat that is ready for direct utilisation to the district heating network.
The heat we buy for the district heating network must be suitable as such for the use of our customers. In practice, this means, as a rule, that the temperature of the heat must be at least 80 degrees Celsius. The situation is assessed in each case separately before joining.
Please contact our sales team and together we can assess the best way of utilising the surplus heat.
The fixed fee covers the costs arising from the customer connection, such as those related to the maintenance, energy metering, remote reading, and systems of the customer connection.
