The initial roll out to support over one million of British Gas’ nearly 16 million customer accounts will be completed in 2012.

British Gas has previously deployed Trilliant’s UnitySuite Head-End Software as the enterprise system to manage all smart energy devices.

The utility now has selected Trilliant to provide the communications equipment to connect smart electric meters, gas meters, in-home smart energy devices and other future home energy devices such as solar, wind and electric vehicle chargers.

The UK Department for Energy and Climate Change has set the target of having smart meters in every home by 2020 or sooner, and this amounts to roughly 47 million meters at 26 million locations, Trilliant said.
