Electra New SCADA System Installation

Electra New SCADA System Installation

Electricity lines company Electra Limited engaged FMS to manage the upgrade of the SCADA front end for its distribution network. The upgrade was part of Electra's investment in ensuring the reliability of supply and accurate control and monitoring across its network, which extends throughout Horowhenua and Kapiti.

A significant stimulus to the upgrade was the low level of trust Electra had in the integrity of its existing system. The company had material doubts over the veracity of the data its system was reporting compared with actual field activity.

To address this concern, FMS began the upgrade with an audit of the system to establish an accurate picture of the field I/O. This provided the platform for the planning and implementation of the new system incorporating existing field MOSCAD and DNP3 RTU's and the latest MOSCAD ACE components from Motorola.  


The work included:

  • Installation and programming of new remote terminal units
  • Installation of new DNP3 Master Station interfaces
  • Integration of new SCADA system with Electra's existing analogue radio and IP data systems
  • After-hours remote access and SMS/txt alert system.
  • Testing and commissioning of the new system, from RTU to operator terminals.

An important factor in the successful implementation of the upgrade was the close collaboration FMS maintained with the Auckland-based software designers engaged by Electra.  This co-operative liaison kept costly downstream compatibility issues to a minimum.

For FMS, the upgrade was also an opportunity to add significant value to Electra's business. In being given the mandate of full technical and engineering control, FMS was able to take a strategic perspective of the upgrade, and as a result, deliver a solution that was future focused and offered Electra the maximum return on its investment.
