Construction of the structural platform for a new Battery Energy Storage System site

Client : G2 Energy

End User : SSE Energy Solutions

Location : Hertfordshire

Contract Value : £524,000

Project complexities, simplified by Alpha:

  1. Interface management across multiple contractors and the client, ensuring foundation zones were delivered in sequence to support transformer placement, battery installation and cable termination without abortive works or programme slippage.
  2. Commencing works on a pre-engineered cut-and-fill platform, requiring validation of ground levels and bearing capacity to maintain compliance with structural tolerances and avoid redesign risk.
  3. Staged return to site for compound surfacing and fence modifications, coordinating final works to align with commissioning timelines and security compliance requirements prior to energisation.

Scope of Works

  • Construction of reinforced concrete foundations for 16 battery containers and nine x 3.6MVA transformers, delivering compliant structural platforms aligned with BESS loading and equipment tolerances.
  • Formation of additional equipment, UKPN substation and control room foundations, ensuring grid interface infrastructure met statutory and DNO specification requirements.
  • Installation of 250m Procter mesh perimeter fencing and secure double compound gates, delivering compliant security in accordance with energy infrastructure protection standards.
  • Installation of drainage and ducting systems, supporting service integration, cable routing and long-term compound resilience.
  • Provision of CCTV and lighting columns, enhancing operational safety, monitoring capability and regulatory compliance.
  • Final compound surfacing works, including stone sub-base and gravel chippings, ensuring a stable, maintainable and energisation-ready BESS environment.
