IN Brief:
- Gresham House has now secured Gate 2 offers for 297MW of battery storage across Cockenzie and Monet’s Garden, both with 2027 connection dates.
- Under NESO reform, Gate 2 status confirms readiness and strategic alignment, and secures a confirmed connection date, connection point, and queue position.
- For storage developers, queue reform outcomes are now directly shaping project finance timing, procurement schedules, and the pace of construction starts.
Gresham House Energy Storage Fund has received a further Gate 2 offer from the National Energy System Operator for its 57MW Monet’s Garden battery energy storage project in North Yorkshire. The offer confirms a July 2027 connection date and follows the earlier Gate 2 offer for Cockenzie, the fund’s 240MW project in East Lothian, which carries a June 2027 connection date.
Together, the two offers move 297MW of pipeline storage capacity into a firmer delivery position under Britain’s connections reform regime. Gresham House has indicated that the new offers take it closer to closing financing on the first three projects in its current development pipeline, with early works under way and long-lead items already ordered. That shifts the focus from speculative queue position to execution discipline, where confirmed dates begin to support procurement sequencing, contractor mobilisation, and final investment decisions.
The importance of Gate 2 lies in what NESO now attaches to it. Projects that meet the new readiness and strategic-alignment criteria secure a confirmed connection date, connection point, and queue position, while projects that do not meet those thresholds fall back to Gate 1 and lose that certainty. For capital-intensive battery schemes, that distinction is critical because it determines whether grid access can be treated as a bankable milestone rather than an indicative assumption.
The backdrop is a reform programme designed to cut through a connections queue that had expanded far beyond what Britain is expected to require by 2030. NESO says the new process is intended to prioritise projects that are both ready to build and aligned with long-term system needs, although the rollout has not been frictionless. That has made each confirmed Gate 2 award more consequential for schemes waiting to move into the build phase.
Gresham House already owns more than 1GW of operational battery storage capacity, so the latest offers are less about proving the technology case than about unlocking the next construction cycle. Queue reform is now acting as a direct gatekeeper for storage deployment, and the projects that clear it first are the ones most likely to move from development plans to steel, switchgear, and energisation.
