Plugging the energy gap

  20th November 2005  —  Issue 116
Britain must start work on about 30 new power stations to stop the lights going out in 2025. Private companies now take the investment decisions, but in a context of technical, regulatory and environmental uncertainty. Can government help?

Within its five-year life span, this government is going to have to make sure that some difficult and potentially unpopular long-term infrastructure decisions are made.

The trickiest of these relate to power generation. In the muscular days of the Central Electricity Generating Board (CEGB), the minister of power (remember Manny Shinwell?) could instruct the board to do what he wanted. That all changed with privatisation in 1989-90. The CEGB vanished, and the role of government changed to that of facilitator and regulator. Yet were the lights went out, the government would be blamed, even though it can no longer order the building of power stations. Tony Blair’s statement at the Labour party conference, promising a fresh energy review early in 2006, and accepting that nuclear energy will have to be part of it, indicates that the government is aware of its predicament.

Supply and demand for electricity

At the moment there is a surplus of generating capacity. The UK has a total capacity of about 77GW (Didcot power station can generate about 2GW) compared with the record peak demand of 61.7GW that occurred at 5.30pm on 10th December 2002. Electricity demand in Britain is growing only slowly so, allowing for a safety margin for breakdowns, surplus capacity ought to exist for at least 20 years. Unfortunately that is not the case.
