The opening part takes us from the epic construction of the first grid in the 1920s and 30s to the challenge of making sure there is power at the flick of a switch today. Using rare archive and vivid personal accounts it reveals the heroic efforts, architectural masterpieces and engineering achievements behind the real power map of Britain. Contributors include author Will Self, urban planner Sir Peter Hall and grid veterans on how Britain first banished darkness and turned on the electric light.

From hoovers to hi-fis, from electric lifts to intensive care units - where would we be if we couldn't plug in to the national electricity grid? The second part of this history of the grid explores how switching on has transformed every part of our lives over the last 60 years. Colour archive reveals a time when having an electric cooker was a status symbol and 'plugged in' music was revolutionary. But the grid didn't just mean gadgets - it has been central to creating a consumer society and shaping the contemporary city. Contributors include The Shadows' guitarist Bruce Welch, author Will Self and architect Mike Davies, all talking about how electrification has sparked modern Britain into life.

Miners, nuclear scientists, politicians, environmentalists and even the City have all wrestled for control of the national electricity grid and the power that it has brought. The final film in this history of the grid charts how it has been the battleground for conflicts that have changed and shaped Britain. Key players from the miners' strikes reveal why the industrial action of the 70s and 80s had such different impacts on electricity supply. The film also uncovers how Britain lost her lead in the field of nuclear power. Contributors include former conservative cabinet minister Lord Jenkin, author Will Self and veterans of all the different fuels. They examine the cost of our love affair with power and consider the perils of life without it.
