Business areas

Lyse has three business areas: energy, infrastructure and telecommunication.

The infrastructure that Lyse is responsible for is critical to society. If there is a protracted interruption to the electricity network or fibre-optic network, large parts of society grind to a halt. It is therefore crucial that Lyse handles the strong growth that is occurring in the region and maintains a high degree of supply reliability.

  • Power grid

    The power grid in Norway is divided into three levels: central grid, regional network and distribution network. Lyse is responsible for development, maintenance and daily operations. The aim is for Lyse to be the most efficient and profitable grid operator in Norway through revitalising operations and development.

    About NOK 500 million is used each year on development, maintenance and operation of the power grid in the region. The main principle is that the electricity supplies must be maintained even if a fault arises on a line or cable. If there is a prolonged interruption to the electricity supply Lyse is required to compensate the customers economically. Lyse shall utilise new technological opportunities to maintain a high degree of supply reliability. We have a large emergency response organisation that can tackle faults around the clock.

  • Fibre network

    15 per cent of Norway's households are connected to the Altibox partnership's fibre-optic network. With almost unlimited capacity the technology is in a class of its own compared with copper cables, and over 70 per cent of all the fibre customers in the country are Altibox customers. Lyse is the second largest provider of broadband in the country, irrespective of technology, and development takes place where there is a profitable basis for the expansion.

    In order to safeguard stable deliveries to our partner network, Altibox has established two national fibre-optic rings, which means that we are independent from others' networks, also at national distances. These rings connect Norway's largest cities together in an operationally reliable network structure with almost unlimited bandwidth. This is the third nationwide high speed network in Norway.

  • District heating network

    Lyse has built a district heating network from the heating plant at Forus. In total, the network is about 90 km in size. Lyse is looking into possibilities to further expand the district heating network. The most relevant axes are from Jåttåvågen and inwards towards the centre of Stavanger, from Forus to the centre of Sandnes and from Forus to the centre of Sola.

    It is necessary to have a good customer base along these axes in order for the development to take place. The district heating network is monitored by the same control centre that monitors the power grid.

  • Gas network

    At the start of the 2000s Lyse began to develop what has now become the biggest in Norway on land. In August 2003 Lyse started to lay a pipeline from the gas plant at Kårstø, and in March 2004 it became operational. Today the gas network extends from Varhaug in the south to Rennesøy in the north and towards the islands in Ryfylke. In total about 570 km of gas pipeline has been built.

    Development of the gas pipeline has taken place in close collaboration with public authorities, including the affected municipalities and DSB (Norwegian Directorate for Civil Protection). Lyse's control centre continuously monitors and follows-up with the network.
