The first EMMA GVS connected to the Western Power Distribution (WPD) Network (UK) has provided instant payback for the customer. Installing the EMMA GVS unit eliminated the need for an expensive electricity network upgrade.
EMMA GVS enabled the customer to grid-connect a 6kW wind turbine on a site with a maximum export capacity of only 4.5 kW.
The EMMA SP40 GVS unit is being used on an Alpaca farm in Cornwall to limit export to that agreed with the Network Operator.
The EMMA unit diverts surplus power to a 6kW immersion heater in a hot water cylinder in the first instance.
When the hot water reaches its maximum safe temperature the GVS unit diverts the surplus power to a filament heater in a goat house.
The unit was installed on 23rd March 2011, a relatively calm day – despite the low wind speed EMMA started generating ‘free’ hot water shortly after being commissioned.
A major achievement
This is the first fully fledged Network Approved export limitation device connected to the electricity grid in the UK. Our patent protected EMMA GVS is the only such device available.

Aside from providing ‘free’ hot water, installation of the EMMA GVS unit has saved this customer thousands of pounds in avoided network upgrade costs (which typically cost between £5,000 – £25,000). It also enabled the Network Operator to facilitate their customer without having to carry out a time consuming upgrade.

The ELITE is the latest addition to the EMMA product family. While we consider it to be the Elite of power diversion and monitoring it is in fact EMMA's little sibling or as we call it EMMA lite.FIND OUT MORE
