Linxon has won an order of approximately $125 million to deliver a turnkey urban compact substation to Ellevio, one of Sweden’s leading distribution network operators. The project site is located close to Värtan harbour and Norra Djurgårdsstaden in the very center of the capital of Sweden.
This is the largest substation project that Ellevio has ever undertaken. As the third large substation contract award for Linxon in Sweden, it is a testament to Linxon’s leading position in the Scandinavian market for large EPC substations.
“We are proud to have once again been entrusted with a mandate to deliver a turnkey substation for the growing city of Stockholm. Our customers clearly believe in the value of Linxon’s engineering solutions. Approximately 1.5 million citizens will ultimately benefit from the refurbishment of Stockholm’s electricity grid,” said Frederic Trefois, CEO of Linxon. “We are eager to meet the customer’s expectations and needs. In this project, compactness is absolutely key due to existing space constraints. This EPC (Engineering, Procurement, Construction) project also poses high demands on coordination between all the involved project functions as well as sub-suppliers which Linxon will expertly manage, building on its well-earned reputation for successfully delivering complex substation projects.”
The Värtan 220 kV substation will contain state-of-the-art products from Hitachi ABB Power Grids – primarily two indoor switchgears to modernize and increase the reliability of the substation. The indoor technology has been chosen because this enables the construction of the substation on a smaller footprint – an important consideration when space is at premium. Also included are power transformers, shunt reactors and a new control and protection system, all these will increase the transmission capacity.
As Stockholm’s population grows, there is a need to strengthen and renew its electricity grid to secure future transmission capacity. To achieve this, over fifty projects need to be implemented over the next 20 years; the Värtan refurbishment is a vital part of that effort.
“This project is a very important step for Stockholm. Investments like this in Värtan are the basis that will enable the city to continue its path towards reliable electrification”, says Johan Lindehag, CEO of Ellevio.
The existing substation has been operational since 1948 (despite a major technological shift in the 1970s). The station has now reached the end of its technical lifespan and it no longer has the required capacity to meet the energy needs of tomorrow.
On-site civil works is planned to start during the summer 2021 and the project duration is estimated to 5 years.

Linxon commenced operations on September 1, 2018, undertaking turnkey electrical alternating current substation projects related to renewable and conventional power generation, power transmission and transportation solutions. Substations enable the efficient and reliable transmission and distribution of electricity. Within the substation, switchgear controls and protects the network from power outages and facilitates reliable electricity supply.
We combine Hitachi ABB Power Grids’ deep technological knowledge and SNC-Lavalin’s project management expertise to create a company dedicated to substations. As one of the leading engineering companies, we help our customers with turnkey solutions in the field of substations for power transmission, renewable energy and transportation. As a single point of contact we combine the accumulated knowhow of key-suppliers and contractors so that customers benefit from efficient solutions, increased industrial productivity and a lower environmental impact.
