22:58 The Minister of State, Department of Energy and Climate Change (Charles Hendry)

The roll-out will play an important role in Great Britain’s transition to a low-carbon economy and will help us to meet some of the long-term challenges that we face in ensuring an affordable, secure and sustainable energy supply. This is a huge and challenging project. It is one of the largest and most comprehensive smart metering projects in the world, and it is the largest change-over programme in the energy industry since the introduction of North sea gas about 40 years ago.
