Ampyr Nabs DCO-Approved 530MW East Yorkshire Solar

• Ampyr Solar Europe snaps up Boom Power’s 530MW East Yorkshire Solar Farm, DCO-approved for 2029, set to power 100,000 homes and boost ASE’s UK PV-plus-storage pipeline past 2.5GW.

Ampyr Solar Europe agreed to acquire Boom Power’s 530-MWp East Yorkshire Solar Farm, a Nationally Significant Infrastructure Project with a Development Consent Order granted in May 2025. The DCO-approved project targets construction and energisation in 2029; Boom Power will stay involved through build and commissioning. If delivered on schedule, EYSF would be among the UK’s largest solar plants to move from consent to operation this decade.

ASE said the deal advances its UK expansion, lifting its domestic pipeline to more than 2.5 GW within a 7+ GW portfolio across the UK, Germany and the Netherlands. EYSF is expected to power about 100,000 homes, and fits ASE’s PV-plus-storage focus amid congested grid queues and rising corporate offtake demand.

What storage capacity and grid connection arrangements will EYSF use to meet 2029 energisation?

• Co-located battery: indicative 200–300 MW, 2-hour duration (≈400–600 MWh), with modular design to scale if grid conditions require
  
• Use cases: peak‑shaving of solar export, capture of curtailed generation, and ancillary services (e.g., Dynamic Containment/Frequency Response) to support firming of export profile
  
• Export capacity: AC export sized below DC peak, targeting ≈400–500 MW firm Transmission Entry Capacity (TEC), subject to final offer
  
• Grid connection: new on-site 400/275 kV substation with step-up transformers and dedicated circuits to the nearest National Grid transmission substation in East Yorkshire, delivered under a bilateral connection agreement
  
• Connection works: new bays at the receiving transmission substation, protection and control upgrades, and compliance with Grid Code and NGESO stability requirements (incl. grid-forming inverter capability where specified)
  
• Programme: phased energisation option in 2029 (initial non‑firm with constraint management via BESS), moving to fully firm export as transmission reinforcements complete
  
• Curtailment strategy: storage-led constraint mitigation, intertrip schemes if required, and participation in ESO constraint markets to preserve 2029 energisation
  
• Flexibility: provision for limited duration or capacity uprate of the BESS within the consented parameters if grid timelines change
