Swedish company ABB has secured a contract from transmission agent and operator Red Eléctrica de España (REE) for the upgrade of electricity transmission infrastructure in the Canary Islands, Spain.
As per the terms of the contract, ABB will supply gas-insulated switchgear (GIS) and shunt reactors.
ABB's high-voltage products business unit managing director Giandomenico Rivetti said: “ABB’s compact GIS technology will help to strengthen the power transmission infrastructure on the picturesque Canary Islands and boost power supplies while preserving their natural landscape and minimising environmental impact.”
The Canary Islands' transmission grid includes approximately 1,350km of power lines and 50 substations. REE has been working on the infrastructure upgrade since 2011 under project MAR. The work will address existing infrastructure deficiencies and integrate the acquired assets into REE's control systems to secure electricity supply in the archipelago.
ABB will be responsible for the project design, supply, and commission of a 145 kilovolt (kV) and 72kV GIS, which will be installed in three indoor substations located on the islands of Lanzarote and Fuerteventura.
The project upgrade work also includes the design, supply, and commission of three shunt reactors 6 megavolt amperes reactive (Mvar) 72kV and one 9MVAr 132kV to be installed in the same indoor substations located on Lanzarote and Fuerteventura.
Upgrade work is expected to be completed by next year and upon completion, the GIS will enable an interconnection between the electricity systems of the islands.
In addition to this project, ABB will support REE with an upgrade of the mainland electricity transmission infrastructure with seven single phase 200 megavolt amperes (MVA) 420 kV autotransformers.
