The company was honoured for its ‘unrivalled’ 3D Engine scheme at an awards event hosted by BBC Radio Guernsey’s Jenny Kendall-Tobias and attended by more than 300 people. The 3D project saw the delivery and installation of a diesel engine weighing 376 tones and is 18m long, 4m wide and 6m high.

In awarding the prize, the judges described the £15m project as having the ‘best local impact’. ‘There were a number of natural, contextual to scale challenges. It is an unrivalled project on a major scale for the island,’ according to the judges.

‘As one of the biggest machines ever brought onshore, the 3D engine project presented a series of complex challenges from initial development work, to the logistics of delivering it to the island and commissioning it into service,’ said Stuart Blondel, the company’s head of asset.

‘Careful planning by Guernsey Electricity’s in-house experts working with the contractor Wartsila ensured these challenges were overcome in this critical scheme, to ensure we have effective on-island power generation capability. Engine 3D is already delivering benefits for Guernsey.’

After a competition, the 3D engine is now called Freddy while its sister engine is known as Trudy. Both are more environmentally friendly than the older engines at the power station and form a key part of Guernsey Electricity’s infrastructure to ensure security of electricity supply alongside the cable link to the European grid.
