METLEN continues to advance the United Kingdom’s energy transition through the delivery of integrated renewable energy projects that combine clean energy generation, battery storage and grid integration. The Bumble Bee Co-Located Renewable Energy Project, developed in collaboration with Cero Generation and its UK development partner Enso Energy, reflects METLEN’s long-term commitment to supporting a resilient, low-carbon and secure energy system for the country.
Located in Nottinghamshire, the project comprises a 78 MWp utility-scale solar PV and a 120 MW Battery Energy Storage System (BESS), designed to deliver both renewable electricity and the flexibility required by a modern power system. By integrating generation and storage within a single hybrid configuration, Bumble Bee will support grid stability, enhance energy security and enable higher penetration of renewables into the UK energy mix. The project also includes the delivery of critical grid connection infrastructure to the West Burton 132kV substation near Doncaster, at a time when network capacity and flexibility are central challenges for the UK’s energy transition.
Once operational, Bumble Bee is expected to generate enough renewable electricity to power approximately 12,300 homes, while avoiding over 13,000 tonnes of CO₂ emissions annually. A dedicated Environmental Management Plan will be implemented to protect and enhance local biodiversity, ensuring that the energy transition is delivered responsibly and in balance with the surrounding ecosystem.
Construction is expected to start shortly, marking another milestone in METLEN’s established collaboration with Cero Generation and reinforcing the Company’s growing role in the UK energy transition landscape.
Nikos Papapetrou, Chief Executive Director, Renewables, Storage & Energy Transition Platform Pillar, METLEN, stated: “We are pleased to support Cero Generation with METLEN’s integrated capabilities, including the delivery of the grid connection works, which are critical for the successful integration of renewable capacity into the UK power system. This project further reinforces METLEN’s position as a trusted partner for complex hybrid renewable projects in the UK and underlines our continued commitment to supporting the country’s energy transition with reliable and high-quality solutions. The Bumble Bee Co-Located Renewable Energy Project is another example of how utility-scale solar combined with battery storage can deliver resilient, flexible and modern energy infrastructure”.
Bumble Bee further expands METLEN’s footprint across the UK and Ireland, where the Company has either completed or is currently constructing more than 80 renewable energy projects spanning utility-scale solar and battery storage systems, with additional assets under development. These projects represent approximately 2.3 GW of solar capacity and approximately 1.6 GWh of battery storage capacity.
Together, these initiatives reflect METLEN’s broader international strategy to scale its renewable energy and storage platform through its integrated developer model, combining strong execution capabilities with long-term commercial structures and market-specific solutions across the full energy value chain. With 1.6 GW of owned projects currently under construction globally, and as a London Stock Exchange-listed company with a long-standing presence in the UK market, METLEN remains focused on delivering reliable, secure and low-carbon energy infrastructure that supports the country’s energy transition agenda.
