Energy intensive users

Verne Holding
United Silicon

We supplied electricity to two new energy intensive users this year and made improvements to customer services via new and improved service processes and a new approach to accessing information on our website. The goal is to ensure that the service process takes a holistic approach to the issues presented by our customers and to ensure the correct solutions and processing.

Grid code

Changes were made to the terms for technical requirements for operating units (D1) this year, alongside a prototype for grid codes for the system contribution (D3). These were introduced to representatives of Landsnet’s Business Council in October 2016 and were subsequently submitted for a review process. Both grid codes will take effect in 2017.

Changes to Grid Code D1 include important adaptation measures for a variety of processing units, e.g. wind turbines. We also reviewed technical requirements and processing units below 10 MW with the option of connecting directly to our transmission network.

Our terms on system contribution are new and were requested by the EFTA Surveillance Authority (ESA) to ensure transparency in cost decisions for the connection of new power stations or users of the transmission system.

Guarantees of Origin of electricity (GOs)

Landsnet issues Guarantees of Origin of electricity (GOs) which confirm that a certain amount of electricity is generated from renewable energy sources. The issue of these certificates increased by a third between 2015 and 2016, reaching a total of nine million or a similar number to those issued in 2014.

Re-certification was carried out for production facilities that received their first certification in 2011. A decision was made not to charge for re-certification in cases where there had been no change in equipment or the operation of the stations. Landsnet’s tariff list for certification management was also increased by 4%. This will take effect from the beginning of 2017. The list was last updated in May 2014.
