The £6 million project to enable the Bunnahabhain Distillery on Islay to almost fully decarbonise its power supply was rejected for debt-funding of £5.7m this year by the SNIB on the grounds that it was “inappropriate and uncommercial”.

AMP Clean Energy is owned by Spanish infrastructure investment group Asterion Industrial Partners.

Madrid-based Asterion has assets under management totalling about €1.7bn (£1.4bn) and has just announced its second infrastructure fund, Asterion Industrial Infra Fund II, targeting €1.3bn. It closed its debut €1.1bn infrastructure fund last year. Both funds focus on European mid-market infrastructure investments.

Asterion acquired AMP Clean Energy through its subsidiary Fossa Holdco in a £55m deal in 2019, The Times reports.

Victor Buchanan, director of developer Dallol Islay, which will build and maintain the plant, said work would start on site next month.

He said: “We had a frantic month, but it’s great to have an investor who understands renewables and finance after wasting so much time having to explain the deal to the Scottish National Investment Bank.”

Richard Burrell, chief executive of AMP Clean Energy, commented: “We support the Scotch Whisky Association’s strong decarbonisation targets for distilleries and their associated supply chains throughout the UK by providing 100 per cent of the upfront capital funding which will help the Bunnahabhain distillery and other facilities reduce their Scope 1 [direct] emissions to meet their Net Zero targets.”

Angus Colquhoun, technical manager at Bunnahabhain’s owner Distell, said: “We’re delighted to have got this over the line at last, and very pleased that we’re able to do it with AMP, who have a great record.”
