Partnership agreed to develop UK battery storage project


Green Investment Group and Bluestone Energy have entered into an agreement to develop up to 2GW of UK battery storage projects.

To meet the UK’s 2050 net zero target, it is estimated the proportion of intermittent wind and solar capacity in the country’s generation mix will need to increase to almost 60% by 2030. Battery storage provides grid operators with the tools and flexibility to deal with this increased variability of supply and finely match it to demand.

A partnership between Green Investment Group (GIG) and Bluestone Energy  will seek to develop up to 2GW of storage projects, while projects representing almost 1GW are already in early stage development having secured grid connection offers.

GIG, which is part of Macquarie Group, is also involved in delivering Australia’s largest privately-funded and fully committed battery storage project in partnership with ENGIE and Fluence at the site of the former Hazelwood Power Station in the Latrobe Valley, Victoria.

Bluestone, a renewable energy developer focussed on decarbonisation and sustainability, has a track record of developing utility scale solar, wind and battery storage projects for a range of players in the industry.

Greg Callman, global head of GIG Energy Technology, said: “Bluestone’s considerable expertise and GIG’s global experience make for a strong partnership that can drive forward the UK’s storage industry. Energy storage clearly plays a critical role in the energy transition. This partnership leverages our mutual experience and expands Macquarie’s global portfolio in this important sector.”

Electricity storage is set to increase in importance as renewable energy rises and as more of the world’s transport capacity moves from hydrocarbon fuels to electricity. Electric vehicles still make up fewer than 3% of the vehicles on UK roads at present but recent data suggests that may now be changing, with the Society of Motor Manufacturers and Traders reporting that electric battery car sales last year, exceeded that of all the past five years combined.

Mike Todd, CEO at Volkswagen Financial Services UK, explained: “The startling sales performance witnessed in 2021 is a recognition that for many an EV is the way to go. This has resulted in the UK tracking 60,000 vehicles ahead of the necessary adoption curve timescale to meet the Climate Change Committee’s target of 55% of all light duty vehicles being battery powered in ten years’ time. This is a vital component of the nation’s net zero ambition.”
