Siemens wind turbine technology is helping an independent UK manufacturer offer increased reliability in its wind turbines.

UK firm Harbon Wind Turbines based in Doncaster, South Yorkshire, supplies units with rated power of around 60kW to farmers and small businesses with relatively low energy requirements.

The company was seeking a solid brand name with reliability and dependability, and approached Siemens Mechanical Drives about gear units and generators just over a year ago.

Since the initial enquiry, Harbon has built a 60kW trial turbine unit and a number of 55 kW units using Siemens products at the heart of the drive system. The gear unit is a low noise Flender FZA 188B K4 with in-line Siemens motor and shaft directly beneath.

Chris Harbon, director of Harbon Wind Turbines, said the Siemens reputation was a major factor in their selection. He said: “As a familiar household name with a proven track record in wind turbine technology, we knew Siemens was a brand we could trust. It’s very important to us to reassure our customers that we use only the very best technology in our products, and it’s helping us win business in a tough economic climate, despite recent feed-in tariff changes.”

One of Harbon’s most recent orders was for a unit installation on the Isle of Coll in the Hebrides. Siemens Mechanical Drives is part of Siemens Industry Automation & Drive Technologies (IA&DT), one of the world’s largest manufacturers of wind turbine technology.

Siemens regional manager Ian Steer, said: “We’re globally recognised but local too, and Harbon liked this. They benefit from our world-leading knowledge, as well as our local base at Leeds for service back-up and parts.”

Harbon added: “Being able to obtain gearbox and motor from a single supplier is also very important to us. We like the whole package – support, technical knowledge, the fact that it’s a technically advanced unit; all these factors matter to us and help us develop our own business.”

Technology to improve energy efficiency in wind power will be one of the many topics discussed in the agenda for BigSwitch Offshore Wind. The international event, which Renewable Energy Technology (RET) is sponsoring, is taking place in Glasgow on 26th and 27th June. It aims to advance technological developments across global offshore wind by encouraging the European renewable energy industry to work with key delegations from the world’s biggest emerging markets, including China and India, as well as the US.
