This is a relatively small business (approximately EUR 300 000 in 2010) but with good potential for growth. The water and sewage department of Troms0 Municipality has undertaken a number of innovative projects to reduce its own energy demands, and aims to be energy neutral in 2014, which implies producing more than 7 GWh of energy themselves. The city is currently extracting energy from the fall of water between the source and the urban settlements, and also by using heat pumps to remove heat from sewage.
