Smart grid: Grid edge management solution to save 5% energy on grid

Entegrus has installed a Grid Edge Management System (GEMS) solution, which is being deployed to reduce energy consumption.

Canadian distribution company, Entegrus, have announced that they have installed a grid management solution, which could help the company save up to 5% energy on the grid.

Entegrus has installed Varentec’s Grid Edge Management System (GEMS) solution, which “is being deployed on the Entegrus power grid to manage dynamic voltage variations which enables reduced energy consumption, increased ability to add renewables to the grid and decreased carbon emissions.”

The GEMS solution employs unique field hardware devices, called ENGOs, which deliver Voltage and VAR regulation on the secondary-side of service transformers. With the placement of ENGO units along a set of feeders, an electric utility is able to achieve dramatically tighter control of voltage, all along the feeders, even in the presence of problematic industrial loads and distributed generation assets.

As a result of this tight system-wide voltage control, a grid operator is able to adjust voltage levels with confidence in order to control demand, while maintaining ANSI or CSA voltage limits. This allows utilities to reduce expensive peak demand events or to boost low voltage customers at the end of the feeder.

The result is as much as a 5% energy reduction while decreasing operating costs through reduced system losses, increasing power quality on the entire feeder, increasing PV solar deployment, and fewer customer complaints.  For this reason, the GEMS solution is like a “swiss army knife” for the grid operator, applying multiple energy-saving “tools” to achieving multiple value streams with only one control solution at the grid edge.

In a statement, it is claimed that the system targets grid infrastructure, unlike many other energy savings programmes, which focus on the customer side, such as commercial buildings and residential homes.

“[The] intelligent GEMS solution presents a new way for electric utilities to regulate lower end-to-end feeder voltages and achieve substantial energy efficiency savings and reduced cost,” said Entegrus’ System Planning Manager, Matthew Meloche.

This cost-effective solution has been demonstrated in multiple electric utilities in the USA, Mexico and Australia, but this is the first deployment in Canada.

“This project is being achieved with the support of the Ontario Ministry of Energy, to advance innovative Smart Grid technologies at electric utility companies in Canada,” said Guillaume Dufosse, CEO of Varentec.

A release by Varentec claims that energy savings results have been demonstrated by impressive field data, which is targeted to be achieved in Ontario as well.
