Mälarenergi now has full control over both water production and water quality thanks to a new control and monitoring system from ABB. The system also prevents energy thieves from stealing the profits.
Mälarenergi is an energy company active in the Mälardalen region of central Sweden. The company is owned by the City of Västerås, which is Sweden´s sixth most populated city with around 138,000 inhabitants. Mälarenergi’s primary mission in the region is to provide electric power, district heating/cooling, broadband, sewage and watersolutions.
Installation during full operation
The water supply network has a total length of 600 km and every second, Mälarenergi purifies 450 liters of water and pumps it to kitchens, bathrooms and garden houses around Västerås. The wastewater then proceeds to Mälarenergi’s treatment plant before returning to the environment. The control and monitoring system now used by Mälarenergi is based on ABB’s 800xA, which is one of the most versatile and reliable systems available today.
“When we started looking at acquiring a new control and monitoring system, the old one was really on its last leg. It was vulnerable to breakdown and difficult to manage, and after careful analysis we decided to replace the entire system
,” says Göran Vikergård, responsible for tap water production at Mälarenergi.
The whole installation was carried out while maintaining full operation – Mälarenergi could not simply switch off Västerås’ water supply. “As expected, the whole replacement process went according to plan. One of the great advantages of AC 800M is the ability to simulate and test software codes to ensure that everything works as planned before closing an old system,” says Per-Arne Ekman, account manager at ABB.
