In order to facilitate the construction of an Inverter Container, Battery Container, Control Container and Transformer Box as part of the Resilience as a Service (RaaS) project at Drynoch, Isle of Skye, PUNCH was appointed to undertake civil and structural engineering duties to design and detail the foundations to support the units. As part of the works, surface water drainage design relevant to site conditions and existing drainage was also necessary.

As part of our services, the PUNCH team carried out site visits to investigate the excavated trial pits. Site investigations and desktop studies were undertaken to inform the foundation design. Our teams carried out an assessment of rainfall characteristics ahead of the design and detailing of below ground surface water drainage system, and designed SuDS and attenuation as relevant to planning requirements.

All structural detail packages were submitted to Ameresco Ltd. and TQs for structural items were promptly responded to by our teams. All CDM regulations were complied with in our roles as Structural Designers, and designer’s risk assessments were carried out throughout the project.
This project was part of a pilot scheme looking to improve energy resilience in remote and rural areas through the use of battery storage and local energy resources in Scotland.

The project was successfully delivered to Ameresco Ltd. by PUNCH in 2025 and is currently undergoing a 2 year Demonstration & Trial Phase. After the trial, it’s performance and scalability will be assessed and, if successful, the RaaS model could be rolled out to other rural sites across the UK.
