A look inside the National Grid

10 March 2014 Last updated at 08:12 GMT

Bang Goes The Theory returns on Monday, with a look behind the scenes at one of the most secret locations in the UK, the control room of the National Grid.

The first in the series looks at the issue of whether Britain might ever come close to running out of electricity - and how the Grid copes with the demands it is already under.

Maggie Philbin spoke to BBC Breakfast about her day in the control room.

Bang Goes The Theory is broadcast at 19:30 on Monday, on BBC One.
