Balance-of-plant for 200 MW utility-scale solar PV plant — Abu Dhabi
EPC delivery of electrical balance of plant for a 200 MW utility-scale solar photovoltaic plant in the western region of Abu Dhabi.
Our role
EPC contractor for electrical balance of plant: HV switchyard, MV collector network, inverter stations, plant SCADA.
The challenge
What we walked into.
Site temperatures regularly exceed 50 °C in summer, with frequent sandstorms. The grid interconnection schedule was non-negotiable — energisation had to align with a separately contracted generation island.
Approach
How we delivered.
- 01FEED and detailed engineering for the 33 kV collection network and 132 kV substation.
- 02Equipment specification for 60+ string inverter stations, MV transformers and 132 kV gas-insulated switchgear.
- 03Procurement of long-lead transformers in parallel with FEED finalisation — saved 10 weeks against critical path.
- 04On-site construction supervision and commissioning in collaboration with the local civil contractor.
Outcome
What changed.
Energisation achieved 9 days ahead of contracted milestone.
Zero lost-time injuries across 14-month construction window.
Commissioning performance test result 1.4% above guaranteed PR.
