Erdgas Ostschweiz AG supplies its shareholders with natural gas through a high-pressure pipeline network with an overall length of 621 km. The shareholders differ greatly in terms of their size, legal form, customer structure and the scope of their services. Local providers operate their own medium/low-pressure network, are separate companies or form part of a public administration. As an interconnected operation, they also offer other supply services such as electricity, water, district heating, sewage disposal and cable network operation.
