Engineering Services for the Energy Sector
From 475-hectare solar farms to grid-scale battery storage, we deliver the flood risk, drainage, and environmental evidence that energy projects need to move through planning and DCO/NSIP processes.
Solar & PV Battery Storage Wind DCO & NSIP
How we help
Flood risk and drainage for large-footprint energy sites.
Energy projects occupy vast areas of open land, often in floodplain or greenfield locations. We deliver the FRA, hydraulic modelling, and drainage evidence that satisfies the Environment Agency, LPAs, and examining authorities.
- FRA and hydraulic modelling for solar, BESS, and wind sites
- Surface water drainage design for large-footprint installations
- DCO flood modelling with climate change scenarios
Our Approach
From site screening to examination support.
-
Site screening
We assess flood risk constraints and identify modelling requirements early.
-
Detailed modelling
We build hydraulic models and test climate change scenarios at scale.
-
Evidence package
We compile FRA, drainage strategy, and environmental reports for submission.
-
Examination support
We support DCO/NSIP hearings and respond to examining authority queries.
