Field Energy has acquired the 200MW Hartmoor battery storage project in Hartlepool, England, from Clearstone Energy, adding to its growing portfolio of energy storage projects across Europe.
The facility, with a capacity to store up to 800MWh of electricity, can supply energy to 500,000 homes for four hours. It will support the integration of renewable energy into the grid by balancing electricity supply and demand, improving grid stability, and mitigating network constraints.
The project, which secured planning approval in 2023, will now be operational by 2026, seven years earlier than initially planned. The timeline was advanced following reforms by the National Energy System Operator (NESO) to accelerate grid connections for essential projects.
Renewable energy generation in northeastern England is expected to grow significantly, with 3.6GW from the Dogger Bank offshore wind project set to connect to the grid between 2025 and 2028. Hartmoor aims to optimize the deployment of this clean energy, reducing energy curtailment caused by grid inflexibility.
Amit Gudka, CEO of Field Energy, emphasized the role of battery storage in enabling a reliable energy transition. “These services are essential for the National Energy System Operator if we want to achieve the government's clean power 2030 target,” he said.
Clearstone Energy founder Ben Pratt noted the collaboration with NESO, which facilitated the accelerated timeline. “The energy system operator's efforts to work with us to accelerate the project's grid connection date is testament to its commitment to enabling the rapid build-out of UK battery storage,” he said.
Proceeds from the sale will support Clearstone's pipeline of battery storage projects totaling 2.2GW, including a 400MW/800MWh project in Devon approved earlier this year. Field Energy now oversees an 11GW portfolio of energy storage projects in various stages of development and construction across Europe.
