The UK government has just given the go-ahead for the building of two new nuclear reactors at Hinkley Point in Somerset. The contract to build and run the power station will go to EDF, the French energy company.

The power station is estimated to cost some £14 billion to build. It would produce around 7% of the UK’s electricity. Currently the 16 nuclear reactors in the UK produce around 19%. But all except for Sizewell B in Suffolk are due to close by 2023, although the lives of some could be extended. There is thus a considerable energy gap to fill in the coming years.

Several new nuclear power stations were being considered to help fill this gap, but with rising capital costs, especially following the Fukushima disaster in Japan, potential investors pulled out of other negotiations. Hinkley Point is the only proposal left. It’s not surprising that the government wants it to go ahead.

All that remains to agree is the price that EDF can charge for the electricity generated from the power station. This price, known as the ‘strike price’, is a government-guaranteed price over the long term. EDF is seeking a 40-year deal. Some low carbon power stations, such as nuclear and offshore wind and wave power stations, have high capital costs. The idea of the strike price is to reduce the risks of the investment and make it easier for energy companies to estimate the likely return on capital.

But the strike price, which will probably be agreed at around £95 per megawatt hour (MWh), is roughly double the current wholesale price of electricity. EDF want a price of around £100 per MWh, which is estimated to give a return on capital of around 10%. The government was hoping to agree on a price nearer to £80 per MWh. Either way, this will require a huge future subsidy on the electricity generated from the plant.

There are several questions being asked about the deal. Is the strike price worth paying? Are all the costs and benefits properly accounted for, including environmental costs and benefits and safety issues? Being an extremely long-term project, are uncertainties over costs, performance of the plant, future market prices for electricity and the costs of alternative forms of power generation sufficiently accounted for? Will the strike price contravene EU competition law? Is the timescale for construction realistic and what would be the consequences of delays? The articles consider these questions and raise a number of issues in planning very long-term capital projects.

The environment has been a growing part of government policy for many years. With the Kyoto Protocol and Europe’s carbon trading system, effort has been made to reduce carbon emissions. Part of UK policy to meet its emission’s target requires substantial investment in infrastructure to provide efficient energy.

Details of the government’s Energy Bill sets out plans that will potentially increase average household energy bills by about £100 per annum, although estimates of this vary from about £90 to £170. This money will be used to finance much needed investment in infrastructure that will allow the UK to meet its carbon emissions target. With this extra cost on bills, energy companies will increase bring in something like £7.6bn. The benefit of this higher cost is that investment today will lead to lower energy bills tomorrow. Essentially, we’re looking at a short-term cost for a long-term gain.

The Energy Bill also delayed setting a carbon emission target until 2016. Crucially, this will come after the next election. Environmentalists have naturally criticised this omission. John Sauven of Greenpeace said:

’By failing to agree to any carbon target for the power sector until after the next election, David Cameron has allowed a militant tendency within his own ranks to derail the Energy Bill … It’s a blatant assault on the greening of the UK economy that leaves consumers vulnerable to rising gas prices, and sends billions of pounds of clean-tech investment to our economic rivals.’

One further problem that this lack of a target creates is uncertainty. The energy sector requires significant investment and in order to be encouraged to invest, firms need assurances. Without knowing the target and hence facing a degree of uncertainty, firms may be less likely to invest in building new power plants. And this investment is crucial. The Government has committed to replacing most coal-fired power stations across Britain with low carbon technology at a cost of hundreds of billions of pounds. However, the Chancellor has said “he would not allow saving the planet to come at the cost of ‘putting our country out of business.’”

When this Energy Bill is published, it is claimed that £110bn of spending on different aspects of the National Grid will occur. The suggestion is that this will generate a further 250,000 jobs by 2030 and will be a big step in the right direction towards creating an economy that is more reliant on clean energy.

Questions

  1. Why does the environment require so much government intervention? Think about the different ways in which the environment as a market fails.
  2. If household bills rise, is there likely to be an income and substitution effect between consumption of ‘energy’ and other goods? Which direction will each effect move in and which do you think would be the largest?
  3. Why is uncertainty such a deterrent for investment? Why does a lack of a carbon emissions target represent uncertainty?
  4. The higher cost of bills today may enable future bills to fall. Why is this? For a household, explain why discount factors could be important here.
  5. Why do some argue that the extra cost to households set out by the government are likely to under-estimate the actual increase households will face?
  6. Is the Chancellor right to say that he will not put our country out of business to save the planet?

In a previous blog, Anyone got a crystal ball?, we reported on the Bank of England’s and other agencies’ difficulty in making forecasts. As the Governor, Mervyn King, said, “There is just enormous uncertainty out there.”

The Bank of England has just published its November Inflation Report. This quarterly publication gives forecasts of inflation, GDP and other indicators. It is clear that forecasting hasn’t become any easier. In his opening remarks, Dr. King says:

Continuing the recent zig-zag pattern, output growth is likely to fall back sharply in Q4 as the boost from the Olympics in the summer is reversed – indeed output may shrink a little this quarter. It is difficult to discern the underlying picture. It is probably neither as good as the zigs suggest nor as bad as the zags imply.

The Inflation Report looks at the various factors affecting aggregate demand, inflation, unemployment and aggregate supply. It is quite clear on reading the report why there is so much uncertainty.

A salutary lesson is to look back at previous forecasts and see just how wrong they have been. The chart above shows the forecasts for GDP made in the Inflation Reports of Nov 2012 and Aug 2011. You can see that they are significantly different and yet just 15 months apart. You might also like to compare the forecasts made a year ago (or even two!) about 2012 with the actual situation today. A good source for this is the Treasury’s Forecasts for the UK economy. This collates the forecasts from a range of independent forecasters.

The inaccuracy of forecasting is an inevitable consequence of a highly interdependent world economy that is subject to a range of economic shocks and where confidence (or lack of it) is a major determinant of aggregate demand. But when firms, governments, individuals and central banks have to make plans, it is still necessary to project into the future and try to forecast as accurately as possible – even though it might mean keeping your fingers firmly crossed.

Virgin’s franchise to run the West Coast Main Line from London to Birmingham, Manchester, Liverpool, Glasgow and Edinburgh was due to expire in December. The Department of Transport thus invited tenders to run a new 13-year franchise, worth around £5 billion, and on 15 August announced that the franchise had been awarded to FirstGroup. It had bid substantially more than Virgin.

Virgin immediately challenged the decision, arguing that FirstGroup’s figures were flawed. According to the second BBC article below:

It argued that FirstGroup’s revenue projections were wildly optimistic – that passenger growth of 6% a year was unlikely given that Virgin had seen growth of 5% a year from a much lower base. This level of passenger growth would have seen FirstGroup’s revenue from the franchise grow by more than 10% a year, which was simply unrealistic, Virgin argued.

And it is not alone. “Everybody in the industry thought that this bid was not sustainable and that the risks had not been taken into account by the Department for Transport,” says rail industry expert Christian Wolmar.

If revenue targets are not met, the franchisee doesn’t have the money to pay the government the promised fee for the contract, which in FirstGroup’s case was back-loaded towards the end of the 13-year term.

After making its decision, the Transport Secretary at the time, Justine Greening, said that the process of assessing the bid was robust and fair and conducted with due diligence. Sir Richard Branson of Virgin strongly and publicly disagreed and Virgin decided to take the Department of Transport to court. The court case was scheduled to begin on 4 October.

However, in preparing its case to put to the court, the Department of Transport uncovered significant errors in the evaluation of the bids. These errors involved the overestimation of passenger numbers, the undervaluation of risk and a failure to take inflation into account. The errors stemmed from inputting the data incorrectly.

The errors were so serious that the new Transport Secretary, Patrick McLoughlin, on the day before the court case was due to begin, announced that he was scrapping the contract to FirstGroup and would invite new bids. All four of the original bidders would have their costs refunded, amounting to some £40 million.

The minister also announced that he was setting up two reviews. One would seek to establish just what went wrong in the assessment of the West Coat Main Line bids and what lessons could be learned. This is due to report at the end of October. The other review would examine the wider rail franchise programme and how bids are appraised. In the meantime, three other franchise competitions had been ‘paused’ pending the results of this second review, due to report in December.

The articles look at the problems of assessing bids and properly taking into account risks associated with both revenue and cost projections. Not surprisingly, they also look at the politics of this amazing and unprecedented U-turn

With the deepening euro crisis, the slide back into recession in many developed countries and the slowing down of fast-growing developing countries, such as China and India, confidence is waning.

But just as pessimism increases, so too does uncertainty. The global economy is getting more and more difficult to forecast. So should economists give up trying to forecast? Should we rely on guesswork and hunch, or looking into crystal balls?

Bank of England representatives have been appearing before the Treasury Select Committee. And they have reiterated the consensus that things are getting more difficult to forecast. As Mervyn King said in his evidence:

There is just enormous uncertainty out there. I have no idea what is going to happen in the euro area.

And this uncertainty is making people cautious, which, in turn, damages recovery. As Dr King went on to say:

There is no doubt that with the additional uncertainty this year there’s evidence of people behaving in a very defensive way, being unwilling to invest and of course the most extreme example of that would be if we were to get to a liquidity trap where essentially the main assets people wanted to hold were claims on the central bank.

Part of the reason for the uncertainty about global growth prospects is uncertainty about what European leaders will decide about the future of the eurozone. Another is uncertainty about how people will respond to the uncertainty of others. But predicting how others will predict is very difficult as they will themselves be predicting what others will predict. This dilemma was observed by Keynes when observing how investors on the stock market behaved, all trying to predict what others will do, and is known as the Keynesian Beauty Contest dilemma (see also).

So are governments and central banks powerless to counteract the uncertainty and pessimism? Can they restore confidence and growth? Members of the Bank of England’s Monetary Policy Committee believe that further action can be taken to stimulate aggregate demand. Further quantitative easing and cuts in interest rates could help as, according to Dr King, we are not yet in a liquidity trap.
