ABB breathes new life into 60-year old VTR turbochargers for Battery Point

Battery Point power station plays an important role in the Western Isles, off the coast of Scotland. The diesel turbine power plant generates approximately 23MW of energy to fulfil the electricity demands for the isles of Lewis and Harris. Recently, ABB overhauled two VTR turbochargers on-board the battery point engine since 1957 to give them a new lease of life and support Battery Point in providing power to the region.

ABB’s VTR turbocharger, the world’s first generation of serialized industrial turbochargers, was launched in 1945 with a groundbreaking burn efficiency of 75% and a pressure ratio of 2. ABB then achieved a major milestone in 1952 following the VTR’s installation on the 18,000-ton tanker, Dorthe Maersk, which became the first ship to be powered by a turbocharged two-stroke engine. 
The VTR turbochargers at Battery Point have been under maintenance by ABB since their installation back in 1957, helping each unit achieve a staggering 60 years of use. Built for absolute longevity, up-keep by the original manufacturer will ensure the turbochargers continue to generate power for the Western Isle’s population during its entire lifetime.

Nevertheless, maintenance has achieved more than simply extending the lifespan of the turbo-chargers. Cleaning carbon deposits from turbocharger fins has helped to maintain the excellent burn efficiency ratio of each unit to improve fuel consumption and lower running costs. The overhauled VTR turbochargers also reduce exhaust gas temperatures and emissions, crucial for helping Scottish and Southern Electricity meet their carbon reduction obligations.

The decision to have maintenance of the VTR turbocharger completed by ABB has saved millions of pounds over the lifetime of the Battery Point power station without the need for lengthy recertifica-tion processes. And, of course, helped to ensure that the people of Lewis and Harris have an electricity source they can rely on.

“All of our customers including Battery Point can trust ABB to take care of their products across the entire lifetime. By using the OEM service and spare parts, Battery Point are sure to receive original effi-ciencies & performance and reliability. We always go the extra mile to make sure our customers make the most of their installations”: Sophie Madeley, LBU Manager – Turbocharging Great Britain & Ireland.
