Gasnätet Stockholm was founded in 1853 and owns and operates the only gas distribution network in Stockholm. Its sister company, Stockholm Gas, is the only third-party gas supplier on the Stockholm network.

The distribution network comprises approximately 520 km of low-pressure pipelines, as well as a separate vehicle gas network of c. 46km, and has connections to over 63,000 residential, commercial and industrial customers.

iCON acquired 100% of Gasnätet Stockholm and Stockholm Gas in November 2016 and realised its interest in 2020.
