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.

Governments and businesses across the world have been trying to become more environmentally friendly, as everyone becomes more concerned with climate change and emissions. In the UK, incentives had been put in place to encourage large-scale organisations to reduce their consumption of gas and electricity. The Carbon Reduction Commitment Scheme began in April 2010, with companies and public-sector orgainisations required to record their energy consumption. Then in April 2011 it was planned that those consuming over 6000 MWh of electricity per year (about £500,000 worth) would be required to purchase ‘allowances’ of £12 for each tonne of carbon dioxide that is emitted by their use of fuel: electricity, gas, coal and other fuels. This would require the organisations working out their ‘carbon footprint’, using guidance from the Department of Energy and Climate Change. In the case of coal and gas, the emissions would be largely from burning the fuel. In the case of electricity it would be largely from generating it.
The government had intended to use the revenue received from the sale of allowances to pay subsidies to those firms which were the most successful in cutting their emissions.
By raising money from the largest emitters via a levy and giving it back as a ‘refund’ to those who cut their usage the most, the government would not have been able to raise any revenue, but it did tackle the core of the problem – reducing emissions. However, following the Spending Review, this scheme will now actually generate revenue for the government. Paragraph 2.108 on page 62 of the Spending Review states the following:
The CRC Energy Efficiency scheme will be simplified to reduce the burden on businesses,
with the first allowance sales for 2011-12 emissions now taking place in 2012 rather than 2011. Revenues from allowance sales totalling £1 billion a year by 2014-15 will be used to support the public finances, including spending on the environment, rather than recycled to participants. Further decisions on allowance sales are a matter for the Budget process.
Over 5000 firms and other organisations will now find that their hard work in cutting usage and being more environmentally friendly will give them much less reward, as the revenue raised from the levy will remain in the Treasury. All that firms will now gain from cutting emissions is a reduction their levy bill. The extra £1bn or more raised each year from the scheme will undoubtedly be beneficial for tackling the budget deficit, but it will no longer provide subsidies to firms which reduce their emissions. Furthermore, PriceWaterhouseCooper estimates that it will cost businesses with an average gas and electricity bill of £1 million an extra £76,000 in the first year and this may increase to an additional cost of £114,000 per year by 2015.
It’s hardly surprising that businesses are angry, especially when this withdrawal of subsidy, which some have dubbed a ‘stealth tax’, was not mentioned in the Chancellor’s speech, but was left to the small print of the Spending Review announcement.
