Hydro

Power Distribution

Our location in the South Island and the experience of our engineers in the hydro industry makes us ideally suited to assist with projects.

Solid Energy Stockton 11kV Substation

We provided a control system to monitor and control 11kv/415V switchgear and transformers using a MicroLogix PLC, RSView SE Supervisory, SEL and Schneider MicroLogic relays.

Solid Energy Stockton 33kV Substation

We provided a control system to monitor and control 33/11kV switchgear and transformers using a MicroLogix PLC, RSView SE Supervisory and SEL relays.

Meridian Energy

MEAPL Remote telemetry system for small hydro stations in Australia monitored and controlled from New Zealand. The system uses RSView32 and satellite internet links to a master station in Twizel. Optimisation of the data communications was an important consideration for this project.

Trustpower

We upgraded the PLC5 control system at Highbank Power station to CompactLogix.  Highbank is a hydo power station drawing water from the Rakaia River.
