The UK economy faces a growing problem of energy supplies as energy demand continues to rise and as old power stations come to the end of their lives. In fact some 10% of the UK’s electricity generation capacity will be shut down this month.
Energy prices have risen substantially over the past few years and are set to rise further. Partly this is the result of rising global gas prices.
In 2012, the response to soaring gas prices was to cut gas’s share of generation from 39.9% per cent to 27.5%. Coal’s share of generation increased from 29.5% to 39.3%, its highest share since 1996 (see The Department of Energy and Climate Change’s Energy trends section 5: electricity). But with old coal-fired power stations closing down and with the need to produce a greater proportion of energy from renewables, this trend cannot continue.
But new renewable sources, such as wind and solar, take a time to construct. New nuclear takes much longer (see the News Item, Going nuclear). And electricity from these low-carbon sources, after taking construction costs into account, is much more expensive to produce than electricity from coal-fired power stations.
So how will the change in balance between demand and supply affect prices and the security of supply in the coming years. Will we all have to get used to paying much more for electricity? Do we increasingly run the risk of the lights going out? The following video explores these issues.

Questions
- What factors have led to a rise in electricity prices over the past few years? Distinguish between demand-side and supply-side factors and illustrate your arguments with a diagram.
- Are there likely to be power cuts in the coming years as a result of demand exceeding supply?
- What determines the price elasticity of demand for electricity?
- What measures can governments adopt to influence the demand for electricity? Will these affect the position and/or slope of the demand curve?
- Why have electricity prices fallen in the USA? Could the UK experience falling electricity prices for similar reasons in a few years’ time?
- In what ways could the government take into account the externalities from power generation and consumption in its policies towards the energy sector?
Centrica, owners of British Gas, has warned that electricity and gas prices in the UK are set to rise in the autumn. Centrica blames this on the expected rise in the costs of wholesale gas and other non-energy inputs.
One of the other ‘big six’ energy suppliers, E.On, has responded by saying that it will not raise energy prices this year. Whether it will raise prices after 1 Jan next year remains to be seen.
Last autumn, household energy prices rose substantially: between 15.4% and 18% for gas and between 4.5% and 16% for electricity. This spring, in response to lower wholesale energy prices, suppliers cut prices for either electricity or gas (but not both) by around 5%.
The government and various pressure groups are encouraging consumers to use price comparison sites to switch to a cheaper supplier. The problem with this is that supplier A may be cheaper than supplier B one month, but B cheaper than A the next. Nevertheless, switching does impose some degree of additional competitive pressure on suppliers.
More powerful pressure could be applied by ‘collective switching’. This is where a lot of people switch via an intermediary company, which sources a deal from an energy supplier. This collective buying is a form of countervailing power to offset the oligopoly power of the suppliers. Such schemes are being encouraged by the Energy Minister, Ed Davey.
The other approach, apart from doing nothing, is for Ofgem, the energy regulator, to impose tough conditions on pricing. But at present, Ofgem’s approach has been to try to make the market more competitive (see also), rather than regulating prices.

Questions
- What are the barriers to entry in the electricity supply market?
- How competitive is the retail energy market at present?
- To what extent do price comparison sites put pressure on energy companies to reeduce prices or limit price increases?
- What scope is there for collective buying of gas and electricity from the six energy suppliers by (a) households; (b) firms?
- Assess Ofgem’s package of proposals for a simpler and more competitive energy market.
Following a 38% increase in profit margins made by energy companies towards the end of 2010, Ofgem (the energy and gas regulator) began an investigation into the activities of energy companies. The review by Ofgem was aimed at determining whether or not consumers should be better protected from the powerful energy companies, many of whom had previously raised prices, forcing some consumers to pay an extra £138 per year. At the time, it was believed that Ofgem might request support from the Competition Commission, but it seems as though the big size energy companies have had a lucky escape. They will not be referred to the Competition Commission, even though critics, in particular First Utility – Britain’s largest independent energy supplier – suggest that Ofgem’s proposals are unlikely to be effective. It seems that the big six have shown sufficient co-operation with Ofgem.
A key reform that Ofgem hope to implement will try to reduce the power of this oligopoly by making it easier for new entrants to gain market share. One such proposal would see the big six auctioning off up to a fifth of the electricity they generate. As the owners of Britain’s power stations, new companies cannot buy gas and electricity on the open market and this reform aims to change that. However, there are concerns that this will be ineffective, as the big six may simply outbid the smaller companies or even just buy and sell electricity from each other, thereby keeping their dominant positions in the market. Although the big six have received constant criticism from all sides, the lack of government support for a Competition Commission inquiry may be related to the need for these companies to invest £200bn in Britain by 2020 to help create and build new energy sources, including wind farms and nuclear power. Without this investment, Britain’s energy supply could be in jeopardy. The following articles consider this energetic debate.

The snow the UK has seen over the past two winters created massive disruption, but that is only one reason for hoping for a milder winter to come. With the cold weather, the UK economy faced threats of gas shortages, as households turned on their heating. However, despite the freezing temperatures, many households were forced to turn off their heating regularly, due to the excessive bills they would face. This trend is expected to be even more prevalent if the 2011/12 winter is as cold, as fuel tariffs are predicted to rise. The Bank of England has said that gas and electricity prices could rise this year by 15% and 10% respectively. British Gas’s Parent company, Centrica said:
“In the UK the forward wholesale prices of gas and power for delivery in winter 2011/12 are currently around 25% higher than prices last winter, with end-user prices yet to reflect this higher wholesale market price environment.”
These predictions might see the average UK household paying an extra £148 over the next year. Although these are only estimates, we are still very likely to see many households being forced to turn off their heating. One thing which therefore is certain: a warmer winter would be much appreciated!

Just as the Bank of England has an inflation target of 2%, so does the ECB. UK inflation has been significantly above its target rate for many months and so has the eurozone’s inflation rate, which is up to 2.8% in April from its previous level of 2.7% the previous month. The increase in the general price level has been fuelled by rising costs of raw materials and high energy prices. Whilst interest rates in the UK have remained at 0.5% in a bid to stimulate economic growth, the ECB has increased interest rates by a quarter point to 1.25% and the latest inflation data may be further pressure for further rises. However, any increase in rates will put more pressure on countries such as Greece, Ireland and Portugal who are facing tough austerity measures and may put their recoveries in jeopardy.
The ECB has been optimistic about growth and it may need to be with this and possibly subsequent interest rate hikes, as they are likely to depress aggregate demand. Furthermore, European Commission’s ‘economic sentiment’ indicator has fallen to 106.2, which is the weakest since November. Eurozone unemployment remains at just under 10%, oil prices remain high and this has depressed optimism across the eurozone countries. The euro, meanwhile, continues to strengthen (up 12% against the dollar over the past year) and this has enhanced the fragile state of affairs in those countries suffering from tough austerity measures. An economist at ING has said:
“The combination of high oil prices, a strong euro, and fiscal and monetary tightening has started to dent the economic mood in the euro zone.”
