Trollhättan Energi

Trollhättan Energi AB is a Swedish municipal company responsible for infrastructure within Trollhättan Municipality. It is a subsidiary of Trollhättan Stadshus AB, the municipal holding company, and is ultimately owned by the City of Trollhättan. The company operates as a multi-utility, covering several essential public services under one corporate roof. Its responsibilities include the district heating network, the water and sewage network, and parts of the fiber network in the municipality. Trollhättan Energi produces and sells electricity, biogas and district heating, produces drinking water and treats wastewater. It is also responsible for the city's waste management and recycling operations. The company's activities are visible to residents through everyday services: customers can sign electricity contracts digitally, report a move, visit the Håjum recycling centre, and receive information about fees for water and sewage, recycling, district heating and the electricity grid. Trollhättan Energi also runs a data centre service for business customers, allowing companies in Trollhättan to rent secure local server space. As a municipal infrastructure provider, Trollhättan Energi plans long-term for the region's energy and water needs. It has announced preparations for the future electricity grid, citing more rechargeable vehicles, new industrial establishments, housing and solar cell parks as drivers of change over the coming decade. It is also building a new recycling centre at Hedeäng, planned to be around 25,000 square metres — nearly three times the size of the current facility at Håjum. Key facilities include the Överby waterworks, water towers in Karlstorp, Lextorp, Sylte and Skogshöjden, the Arvidstorp wastewater treatment plant, combined heat and power plants in Lextorp and Stallbacka, and the Kronogården heating plant. The company communicates with customers in Swedish through its website and provides contact forms and phone lines for service.

Trollhättan Energi AB is a municipal company for infrastructure within Trollhättan Municipality. It is a subsidiary of Trollhättan Stadshus AB, the municipal holding company, and is therefore owned by the City of Trollhättan. The company has been organised as a municipal limited company responsible for a broad range of public utility services. Over time, Trollhättan Energi has consolidated responsibilities that in many municipalities are split between separate companies: district heating, water and sewage, parts of the fiber network, electricity production and sales, biogas, drinking water production, wastewater treatment, and waste management. This multi-utility model allows the municipality to coordinate infrastructure planning across energy, water and waste. The company operates a number of key facilities. These include the Överby waterworks; water towers in Karlstorp, Lextorp, Sylte and Skogshöjden; the Arvidstorp wastewater treatment plant; combined heat and power plants in Lextorp and Stallbacka; and the Kronogården heating plant. These assets underpin the daily delivery of drinking water, district heating and electricity to households and businesses in Trollhättan. In the 2020s, Trollhättan Energi has focused on modernising and expanding its infrastructure. It has planned for the electricity grid of the future, citing more rechargeable vehicles, new industrial establishments, housing and solar cell parks as drivers of change over the coming decade. It has also begun construction of a new recycling centre at Hedeäng, planned to be around 25,000 square metres — nearly three times the size of the current facility at Håjum. In addition, the company has opened its data centre to business customers, offering secure local server space. The company adjusts its fees in response to regulatory and cost changes. It has announced changes to water and sewage, recycling, district heating and electricity grid fees from 1 January 2027, while the fiber fee remains unchanged. It also adjusted the fixed electricity grid fee from August 2026 after authority fees increased. Trollhättan Energi continues to communicate with customers through its website, contact forms and phone lines, and provides practical services such as digital electricity contracts and move notifications.
