Diageo’s €300m Renewable Energy-Powered Brewery in Ireland

Ireland’s brewing industry has gained a major new landmark with the official opening of Diageo’s Littleconnell Brewery in Newbridge, Co. Kildare. 

Opened by Ireland's Taoiseach (Irish Prime Minister) Micheál Martin alongside Diageo CEO Sir Dave Lewis, the nearly €300m (US$349.6m) facility signals both confidence in Irish brewing heritage and a clear ambition for global growth. 

More significantly, the announcement of a further estimated €400m (US$466m) investment over the next three years places Littleconnell at the centre of Diageo’s international production strategy. 

The development forms part of the company’s almost €1bn (US$1.17bn) capital investment programme across Ireland between 2020 and 2029, reinforcing the country’s importance within the global drinks market.

A brewery built for global demand

Constructed in under 18 months on a 40-acre campus in Co. Kildare, Littleconnell Brewery has been designed to supply both Irish and international markets with a portfolio that includes Rockshore, Harp, Smithwick’s, Kilkenny and licensed beers such as Carlsberg. 

The scale of the investment reflects how Ireland is increasingly being positioned as a strategic export and innovation hub within Diageo’s worldwide brewing network. 

With Guinness continuing to experience strong international demand, the planned Brewery 2 development, dedicated entirely to Guinness and Guinness 0.0 production, will more than double the site’s overall capacity and further strengthen Ireland’s role in supporting the brand’s global expansion.

“The demand for Guinness and Guinness 0.0. is surging,” says Dave.

“Today Diageo is proud to unveil our new state of the art brewery at Littleconnell, part of our €1bn (US$1.17bn) investment in Ireland. 

“How fitting that it’s in County Kildare, the birthplace of Arthur Guinness.”

Scaling sustainably

One of the defining aspects of the Littleconnell project is how sustainability has been integrated alongside expansion. 

Powered by 100% renewable electricity, the brewery incorporates advanced brewing and process technologies designed to reduce both energy and water consumption.

Diageo expects the site to avoid up to 15,000 tonnes of carbon emissions annually compared with a similar-scale facility, aligning with the company’s Spirit of Progress sustainability commitments. 

As global beverage companies face increasing pressure to decarbonise operations while maintaining production growth, Littleconnell offers a blueprint for how future brewing infrastructure may evolve, particularly as Guinness 0.0 continues to gain traction internationally.

“Ireland plays a key role in Diageo’s global beer supply and Littleconnell is central to enabling future growth in Guinness exports,” says Colin O’Brien, Category Head – Global Beer Supply, Diageo.

“This site is part of Diageo's near €1bn (US$1.17bn) investment programme that strengthens capacity, builds resilience across our brewing network and supports the global growth of Guinness and Guinness 0.0 from Ireland. 

“Littleconnell, together with the developments at St James’s Gate, will enable growth in overall beer exports from Ireland and help us deliver on Diageo’s Spirit of Progress sustainability commitments.”

Regional investments for international impact

While the brewery has clear international ambitions, its economic impact within Ireland is equally significant.

The project supported approximately 650 jobs during construction and has already created more than 50 highly skilled permanent positions in the region.

“Today’s opening of Diageo’s new Littleconnell Brewery in Co. Kildare is a powerful vote of confidence in Ireland and in our future as a world-leading, sustainable food and drink exporter,” said Micheál, when officially opening the Littleconnell brewery.

“This landmark facility forms part of Diageo’s near €1bn (US$1.17bn) investment in Ireland between 2020 and 2029, underlining the central role Ireland plays within the company’s global brewing network and highlighting the strength of our agri-food and drinks sector on the international stage.

“By choosing to invest at this scale in Ireland and to lead the way in next-generation, low-carbon brewing, Diageo is supporting skilled jobs, regional development and export growth, while helping Ireland advance its climate ambitions through innovation.”

Supported by Enterprise Ireland, the development underlines how large-scale food and drink investments can deliver both local employment and long-term export value. 

Together with completed upgrades at St James’s Gate and Diageo’s Belfast packaging site, Littleconnell forms part of a broader strategy to increase production capacity, support Guinness 0.0 growth and future-proof Ireland’s brewing sector for the next decade of international demand.
