Following a successful trial of the technology across more than 50 sites, the pubco plans to introduce the Cornelius ecoFLO Smart Pump System to all 1,800 of its managed sites.
The system controls the run time of the cooler during periods when no beer is being sold without impacting product cooling during serving sessions.
The trials that took place saw an average energy saving of more than 50% per cooler when compared to the units fitted with industry standard pumps.
Greene King head of brewing and operations David Carr told The Morning Advertiser that the technology would lead to "more consistent" beer temperature.
“While beer quality is absolutely paramount to us, this project was driven more for its environmental benefits,” said Carr.
“What we can say is that there will not be any quality reduction from this initiative and it should help deliver a more consistent ‘in-glass’ temperature.”
Carr added that the company was currently investigating how the technology could be offered to licensees in Greene King’s tenanted and leased estate.
Renewed apprenticeship commitment
Greene King is also renewing its commitment to its Get Into Hospitality scheme, run in partnership with The Prince’s Trust.
As part of National Apprenticeship Week, the company’s chief executive, Rooney Anand, said: “It’s more important than ever that we continue to bring young people into the hospitality industry and show that it can provide a stable, exciting and rewarding career path.
“It is becoming recognised that there is a skills shortage for back of house roles, so we’re keen to develop talent in this area.”
