Renewables & BESS

Electrical engineering for solar, wind and battery storage.

Connection strategy, electrical balance of plant and compliance evidence for generation and storage projects — carried from feasibility through to energisation and the compliance sign-off that follows.

A renewable project lives or dies by its connection. We help developers understand what an offer really requires, design the plant to meet it, and produce the evidence the network operator needs before it will let you energise.

Behind the meter we design the collector network, the substation and the protection and control that hold it together, whether the site is a 5 MW solar farm on an 11 kV feeder or a 400 MW storage project at 400 kV.

Grid connection

  • Connection strategy, application support and offer review
