MV substations, reticulation and grid connection

On mines, heavy industrial sites and large commercial properties, the solar plant is only one part of the job. We build the intake substations, 33 kV and 11 kV reticulation, transformers, protection and metering around the plant, and integrate PV with storage and generators under a single energy management system.

What we deliver

MV and HV substations, reticulation and switchgear
Transformers, protection and metering
Grid impact, load flow, short-circuit and dynamic studies
Grid code compliance strategy and testing
Regulator registration: NERSA (South Africa), ZERA (Zimbabwe), ESERA (Eswatini)
Utility connection applications and agreements: Eskom, ZETDC, EEC
Commissioning, plant controller and SCADA integration with the client's energy management system

Approvals and long-lead equipment (HV transformers and switchgear) govern the programme, so permitting runs in parallel with design and long-lead items are released early.
