Whyte & Mackay and ENGIE sign renewable power and supply agreement linking solar and hydro generation with 24/7 reporting
Whyte & Mackay and ENGIE have announced an innovative energy agreement incorporating 24/7 matching, helping to deliver more sustainable whisky distilling through locally sourced power to the Isle of Jura.
The partnership will see Whyte & Mackay and ENGIE enter into a new 36-month renewable electricity agreement, with Whyte & Mackay’s energy needs provided by locally produced solar and hydro generation, under a single bespoke contract. The agreement is designed to provide long-term energy resilience, support decarbonisation ambitions, and deliver traceable 24/7 reporting This reporting matches Whyte & Mackay’s electricity consumption with the solar and hydro production on an hourly basis.
Under the agreement, Whyte & Mackay will contract with ENGIE for 100% of its energy supply needs backed by a solar and hydro Power Purchase Agreement (PPA) with the support of Inver Hydro. These assets are located on the Inver Estate, a short distance to Whyte & Mackay’s distillery on the Isle of Jura, Scotland, aligning renewable energy and the local community. The agreement includes 24/7 reporting, giving Whyte & Mackay enhanced visibility over its renewable power position to support more detailed energy management and reporting.
Shane Healy, Distilling Director – Whyte & Mackay Ltd. said: “This agreement with ENGIE marks an important step in our Green Print strategy, giving us a renewable electricity solution that combines long-term certainty with greater transparency. By linking solar and hydro generation within one structure, and with 24/7 reporting built into the agreement, we are strengthening our ability to manage energy more effectively. This also supports our wider sustainability ambitions to be carbon neutral in our own operations by 2030 and positively supporting our local communities across our sites that are powered by the carbon neutral electricity.’
Rob Wells, Chief Executive Officer – ENGIE Energy Supply UK said: “We are pleased to support Whyte & Mackay with a tailored renewable energy agreement that brings together supply, renewable sourcing, and detailed reporting in one integrated solution. By combining solar and hydro technologies, alongside 24/7 reporting, this deal demonstrates how we can collaborate closely with customers to create flexible energy solutions that support operational needs and decarbonisation goals.”

About Whyte & MacKay

About Inver Hydro
Inver Hydro Ltd. is wholly owned by the Lithgow family whose history in hydropower dates back to 1906 and who bought the Inver Estate on Jura in 1925. The Estate was not previously connected to mains electricity, with early electrical requirements being serviced by a waterwheel and DC generator. This evolved in the 1980’s to a standalone mini-hydro scheme which powered a small private network. The 2MW Inver Hydro scheme was conceived and built in 2012 which finally connected the Estate to mains electricity. Adding the solar PV array in 2026 has increased the site’s export to over 10.7GWh a year, enough to power the whole of Jura and around a third of neighbouring Islay.
The Lithgow family have been involved in renewable energy for over a century. They have built and continue to operate six other mainland hydro schemes and two community windfarms.
