LEAP IN NucLEAR CAPITAL CosTs The Central Electricity Generating Board may order two oil-fired power stations this year despite the sharp jump in oil costs - if growth forecasts justify a bigger programme.

Provisional CEGB estimates show that the huge leap in nuclear construction costs, reflecting the general inflationary trend, is offsetting the competitive gain from rising oil prices.

Present plans are aimed at ordering at least one station this year - the 3,300 MW £250 million oil-fired station on the Isle of Grain at the mouth of the Medway.

A question mark now hangs over whether demand in the mid-70's (the time-lag between contracts and completion of a power station is around five years) will be sufficient to include a second station in this year's programme and whether it will be oil or nuclear-fired.

The outcome depends on planning work now being conducted by the CEGB, the load forecasts for the winter of 1976-77, and the wider problem of ensuring a steady workload for plant manufacturers to avoid the bunching of orders.

The Electricity Council will conduct its all-important review of future demand next month. Many of the present indications suggest that electricity growth will not require a second station, although the CEGB is known to be anxious to increase the 'safety' margin between generation supply and demand from seventeen per cent to twenty-three per cent because of repeated plant breakdowns.

If a second station is ordered the current signs are that it could well be ollfired, since provisional calculations based on price projections up to the end of the 1970's suggest that oil will still be competitive with nuclear energy.
The estimates might prove to be over-optimistic, but inflation is playing havoc with the capital cost of nuclear power stations and the CEG B is said to be 'horrified' at some of the latest estimates.
There was a forty per cent jump to £130 million in the cost of the Hartlepool advanced gas-cooled reactor station ordered in 1963 and the 'sister' station at Heysham, on the Lancashire coast, ordered last year.
The latest cost estimates for the 2640 MW nuclear station, Sizewell 'B' on the Suffolk coast, are believed to be on a par with the bigger Isle of Grain oil-fired station. The net result is that the Sizewell plant, originally expected to be ordered this year has been pushed further down the queue.
The Isle of Grain will be the first oil-fired station ordered for seven years, and by tighter contract control the CEGB is hoping to reduce the delays which have put the whole power station construction programme eighteen months behind schedule.
