Circularity in our heat operations

SamEnergi is Vattenfall’s initiative to make it easier to harness excess heat from our surroundings.

Through a smart and standardised model, we can buy excess heat from companies, transfer it into the district heating network, and utilise it where it creates the greatest value – for example, to heat homes, offices, and commercial buildings. This means that energy that would otherwise be lost becomes a valuable resource for the local community.

SamEnergi operates along two complementary tracks. The first focuses on capturing excess heat from businesses already located close to our district heating networks, such as data centres, bakeries, and smelters. Previously, this was mainly an option for heavy industry, but SamEnergi makes it possible for smaller companies to participate as well. 

The second track looks ahead. To increase the availability of excess heat in the future, SamEnergi identifies strategic locations where new energy intensive industries – for example, data centres – can establish themselves with optimal conditions for heat recovery.

As proximity to the district heating network is crucial for minimising heat losses and ensuring a viable business case, Vattenfall actively prepares selected sites and secures key prerequisites such as buildable land and sufficient power capacity.

Through SamEnergi, energy can be utilised twice. This reduces the need for primary energy and supports a more circular and resource efficient energy system.
