Waste incineration at Högdalenverket

Högdalenverket, which is one of Europe’s most modern installations for energy extracted from waste, produces electricity and heat from Stockholm’s combustible household waste and industry waste. Högdalenverket is an important component in the district heating network of southern Stockholm.

The waste-fired Högdalenverket is one of Stockholm’s largest combined heat and power plants. It provides environmentally-friendly heat and electricity to large parts of southern Stockholm. The advantage of waste incineration is that you avoid landfilling of waste, which can cause leaking problems of methane and heavy metals. The emissions from waste incineration have, thanks to efficient flue gas cleaning units, a relatively low environmental impact.

Ever since 1970, Högdalenverket has been recycling energy out of waste – firstly as electricity, but from 1979 also as heat. Today the plant has the capacity to receive around 700,000 tonnes of waste per year.

The plant is owned by Stockholm Exergi, which is co-owned by Fortum and the municipality of Stockholm. Stockholm Exergi has several waste and biofuel incineration plants in Stockholm. In total, Stockholm Exergi’s plants produce a total of 2,138 GWh of energy (electricity and heat) from waste for the citizens of Stockholm.

New technology makes the electricity grid smart

Smart sensors, redundant radio communication, AI-based decision support and advanced data analysis makes it possible to detect and position faults in the electricity grid immediately. In 2018, Exeri’s system was put into operation in the electricity grid around Malå, Sweden. Skellefteå Kraft installed the system for monitoring an approximately 40 kilometer long section and after the positive evaluation of the installation, the company now chooses to proceed with installation of monitoring and sensors on a large part of the electric grid.
