NES energy efficiency and flexibility solution for the Swiss market


NES deploys its dual relay meter with sophisticated control software for DSOs in Switzerland

Networked Energy Services Corporation (NES), a global smart grid solution provider with the industry’s leading Energy Applications Platform (EAP), has deployed its integrated HW and SW solution for dual relay control for business and residential consumers.

The NES solution allows DSOs to integrate the normally separate meter and relay control capabilities into the meter, integrating them for local, scheduled and remote control through innovative software solutions.

As part of this innovation, highly reliable and secure OSGP communication is used to integrate the control of the relays with the standard metering control and information over the PLC network. This is made possible by the high communication SLAs, typically over 99.7%, which are a feature of NES’s implementation of OSGP.

The dual relays can be controlled from the meter optical interface (for installation and local control in special conditions), by schedules which can be loaded remotely from the Head-end System and run independently on the meter, or by remote commands sent from the SCADA platform. Monitoring of the service is provided by a “heart-beat” function which implements a fallback to local control if control via remote communication fails.

This solution can replace legacy Ripple Control systems, used to assist in grid loading and re-start operations and can also control demand by restricting supply to heavy-load drawing applications at the consumer premise.

Combining the features of metering and relay control within one physical unit and one communication connection reduces the time and cost of deployment and greatly simplifies the operation of the system.

This solution has been co-developed with VIVAVIS but is available through NES to other customers.

Said David Thomson, NES President & CEO: “Our solution confirms NES’s role as a vendor that is leading improvements in energy efficiency and availability. Although driven by requirements from the Swiss market, we can see this solution having applications in many markets where relays are used in meters to control demand in order to achieve reliability in the service and maintain optimal performance of infrastructure.”

“This solution is perfect for the Swiss market” said Ingo Schmitt, Business area manager metering, VIVAVIS. “The cost effectiveness of having two functions consolidated into one platform, the re-use of existing secure and reliable OSGP communication and the various modes of local, scheduled and remote operation, means that DSOs can achieve ripple control and demand response more effectively.”
