Soaring gas prices (updated 1/10/22)

International wholesale gas prices have soared in recent months. This followed a cold winter in 2021/22 across Europe, the bounceback in demand as economies opened up after COVID and, more recently, pressure on supplies since the Russian invasion of Ukraine and the resulting restricted gas supplies from Russia. The price of gas traded on the UK wholesale market is shown in Chart 1 (click here for a PowerPoint). Analysts are forecasting that the wholesale price of gas will continue to rise for some time. The higher price of gas has had a knock-on effect on wholesale electricity prices, as gas-fired power stations are a major source of electricity generation and electricity prices.

In the UK, domestic fuel prices were capped by the regulator, Ofgem. The cap reflected wholesale prices and was designed to allow electricity suppliers to make reasonable but not excessive profits. The cap was adjusted every six months, but this was been reduced to three months to reflect the rapidly changing situation. Prices are capped for both gas and electricity for both the standing charge and the rate per kilowatt hour (kWh). This is illustrated in Chart 2 (click here for a PowerPoint).

The effects of the cap were then projected in terms of a total annual bill for a typical household consuming 12 000 kWh of gas and 2900 kWh of electricity. Chart 3 shows the typical fuel bill for the last four price caps and, prior to the mini-Budget of 23 September, the projected price caps for the first and second quarters of 2023 based on forecasts at the time of wholesale prices (click here for a PowerPoint). As you can see, wholesale gas and electricity prices account for an increasing proportion of the total bill. The remaining elements in cost consist of profits (1.9% assumed), VAT (5%), operating costs, grid connection costs and green levies (around £153). The chart shows that, without government support for prices, the price cap would have risen by 80.6% in October 2022 and was projected to rise by a further 51% in January 2023 and by another 23% in March 2023. If this were to have been the case, then prices would have risen by 481% between the summer of 2021 and March 2023.

This was leading to dire warnings of extreme fuel poverty, with huge consequences for people’s health and welfare, which would put extra demands on an already stretched health service. Many small businesses would not be able to survive the extra fuel costs, which would lead to bankruptcies and increased unemployment.

Future wholesale gas prices

Energy market analysts expect wholesale gas prices to remain high throughout 2023, with little likelihood that gas supplies from Russia will increase. Some European countries, such as Germany, have been buying large amounts of gas to fill storage facilities before winter and before prices rise further. This has added to demand.

The UK, however, has only limited storage facilities. Although it is not an importer of gas from Russia and so, in one sense, storage facilities are less important at the current time, wholesale gas prices reflect international demand and supply and thus gas prices in the UK will be directly affected by an overall global shortage of supply.

What would have been the response to the projected rise in gas prices? Eventually demand would fall as substitute fuels are used for electricity generation. But demand is highly inelastic. People cannot readily switch to alternative sources of heating. Most central heating is gas fired. People may reduce consumption of energy by turning down their heating or turning it off altogether, but such reductions are likely to be a much smaller percentage than the rise in price. Thus, despite some use of other fuels and despite people cutting their energy usage, people would still end up spending much more on energy.

Over the longer term, new sources of supply of gas, including liquified natural gas (LNG), may increase supply. And switching to green energy sources for electricity generation, may bring the price of electricity back down and lead to some substitution been gas and electricity in the home and businesses. Also improved home insulation and the installation of heat pumps and solar panels in homes, especially in new builds, may reduce the demand for gas. But these changes take time. Chart 4 illustrates the situation (click here for a PowerPoint).

Both demand and supply are relatively inelastic. The initial demand and supply curves are D1 and S1. Equilibrium price is P1 (point a). There is now a fall in supply. Supply shifts to S2. With an inelastic demand, there is a large rise in price to P2 (point b).

Over two or three years, there is a modest fall in demand (as described above) to D2 and a modest rise in supply to S3. Price falls back somewhat to P3 (point c). Over a longer period of time, these shifts would be greater and the price would fall further.

Possible policy responses

What could the government do to alleviate the problem? Consensus was that the new Conservative Prime Minister, Liz Truss, and her Chancellor, Kwasi Kwarteng, would have to take radical measures if many households were to avoid severe hardship and debt. One proposal was to reduce VAT on domestic energy from 5% to zero and to cut green levies. Although this would help, it would make only a relatively small dent in people’s rising bills.

Another proposal was to give people cash payments to help with their bills. The more generous and widespread these payments, the more costly they would be.

One solution here would be to impose larger windfall taxes on oil and gas producers (as opposed to retailers). Their profits have soared as oil and gas prices have soared. Such a move is generally resisted by those on the right of politics, arguing that it could discourage investment in energy production. Those on the centre and left of politics argue that the profits are the result of global factors and not because of wise business decisions by the energy producers. A windfall tax would only take away these excess profits.

The EU has agreed a tax on fossil fuel companies’ surplus profits made either this year or next. It is also introducing a levy on the excess revenues that other low-cost power producers make from higher electricity prices.

Another proposal was to freeze retail energy prices at the current or some other level. This would make it impossible for energy suppliers to cover their costs and so they would have to be subsidised. This again would be very expensive and would require substantially increased borrowing at a time when interest rates are rising, or increased taxation at a time when people’s finances are already squeezed by higher inflation. An alternative would be to cap the price North Sea producers receive. As around half of the UK’s gas consumption is from the North Sea, this would help considerably if it could be achieved, but it might be difficult to do so given that the gas is sold onto international markets.

One proposal that was gaining support from energy producers and suppliers is for the government to set up a ‘deficit fund’. Energy suppliers (retailers) would freeze energy prices for two years and take out state-backed loans from banks. These would then be paid back over time by prices being capped sufficiently high to cover costs (which, hopefully, by then would be lower) plus repayments.

Another policy response would be to decouple electricity prices from the wholesale price of gas. This is being urgently considered in the EU, and Ofgem is also consulting on such a measure. This could make wholesale electricity prices reflect the costs of the different means of generation, including wind, solar and nuclear, and would see a fall in wholesale electricity prices. At the moment, generators using these methods are making large profits.

The government’s response

On September 23, the government held a mini-Budget. One of its key elements was a capping of the unit price of energy for both households and firms. The government called this the Energy Price Guarantee. For example, those households on a variable dual-fuel, direct-debit tariff would pay no more than 34.0p/kWh for electricity and 10.3p/kWh for gas. Standing charges are capped at 46p per day for electricity and 28p per day for gas. These rates will apply for 2 years from 1/10/22 and should give an average annual household bill of £2500.

Although the government has widely referred to the ‘£2500 cap’, it is the unit price that is capped, not the annual bill. It is still the case that the more you consume, the more you will pay. As you can see from Chart 3, the average £2500 still represents an average increase per annum of just over £500 per household and is almost double the cap of £1277 a year ago. It will thus still put considerable strain on many household finances.

For businesses, prices will be capped for 6 months from 1 October at 21.1p per kWh for electricity and 7.5p per KWh for gas – considerably lower than for domestic consumers.

The government will pay subsidies to the retail energy companies to allow them to make sufficient, but not excess, profit. These subsidies are estimated to cost around £150 billion. This will be funded by borrowing, not by tax increases, with the government ruling out a windfall tax on North Sea oil and gas extracting companies. Indeed, the mini-Budget contained a number of tax reductions, including scrapping the 45% top rate of income tax, cutting the basic rate of income tax from 20% to 19% and scrapping the planned rise in corporation tax from 19% to 25%.

Oligopolies galore

Oligopoly: it’s a complex market structure and although closer to the monopoly end of the ‘Market Structure Spectrum’, it can still be a highly competitive market. The characteristics are well-documented and key to the degree of competition within any oligopoly is the number of competitors and extent to which there are barriers to entry.

The greater the barriers and the fewer the competitors the greater the power the established firms have. This can then spell trouble for pricing and hence for consumers. The following articles are just some examples of the oligopolies that exist around the world and some of the benefits and problems that accompany them.

Frosty supplies from Russia

Last year, we felt the cost of the cold weather and whilst we haven’t seen such low temperatures this year, gas shortages are also emerging. Across Eastern Europe, temperatures have fallen well below -30ºC and so demand for gas has unsurprisingly increased.

Thanks to these low temperatures, Russian gas supplies are running low and several countries have seen their deliveries of gas fall. However, the Russian gas monopoly, Gazprom has said that supplies have not been cut and that it has been exporting more gas during these cold times. The blame, according to Alexander Medvedev (the Deputy CEO of Gazprom), lies with the Ukraine taking gas at a pace significantly above contracted levels. The following articles consider this issue.

An energetic price war

In an earlier blog Energy profits margins up by over 700% we analysed the increasing pressure on many households as they saw their energy bills increase in price year on year. This helped the big six energy companies achieve a 700% rise in their profits.

However, it also sparked interest by the regulator Ofgem, which was looking to ensure that consumers found it easier to make price comparisons and create a more competitive market. One issue that Ofgem were looking into was how to make the energy sector more open to competition, given that the big six companies own the power stations and hence this acts as a barrier to the entry of new firms.

The latest announcements from some of the big energy companies will therefore come as a pleasant turn of events for Ofgem. On Wednesday January 11th 2012, EDF announced that it would be cutting its energy prices by 5% from 7th February in response to a fall in wholesale costs. Only a day later, Npower announced its plans to cut its tariffs by 5% from 1st February. British Gas cut its prices by 5% with immediate effect and SSE will reduce its gas prices by 4.5% from March 26th.

Is this a sign that the market is becoming more competitive thanks to Ofgem or is there another explanation? For the past 2 winters, temperatures have been consistently below freezing and hence demand for gas/electricity was at an all time high, speaking concerns of gas shortages. However, with the mild winter we are currently experiencing (I hope I haven’t jinxed it!) demand for heating etc has been significantly lower, which has reduced wholesale costs and the big six companies have begun to pass these savings on to their customers. Yet, despite this seemingly good news, are they being as ‘kind’ as we think? Most of the companies are cutting their prices by about 5%, yet wholesale prices fell by significantly more than that. Furthermore, over the past few years, customers have seen their tariffs increase significantly – by a lot more than 5%. To some extent, this confirms the criticism levelled at the energy sector – when costs rise, they are quick to pass on the full costs to their customers. But, when costs fall, they are slow to pass on only a fraction of their cost savings. The following articles consider this issue.

Stop gassing about gas and produce it!

The UK section of the North Sea used to be sufficient to supply all of the country’s gas requirements, but now some has to be imported from countries such as Norway. With the cold weather, the usage of gas has increased to record levels and there are now concerns for future supplies, especially if the cold weather returns.

However, the National Grid has said that there isn’t a problem, despite a glitch with a Norwegian gas supply. Gas supplies from various sources have been increased to deal with this record demand. There have been calls for Britain to build more gas storage facilities and the National Grid did issue ‘gas balancing alerts’, asking power firms and other large industries to cut back on their gas consumption. There are suggestions that even if supplies of gas aren’t a problem at the moment, we could see serious shortages in a few years.

Following growing demand for gas supplies, wholesale prices rose, but they did fall again when supplies were increased. Prices of household bills could be affected in the future, but for now, it’s too soon to tell. However, rising prices could spell further trouble for ours and other economies suffering from extreme weather on top of a financial crisis. Economic recovery could be put in jeopardy.

This fear of gas shortages and security of supply has led environmental and business groups to argue that Britain needs to diversify its energy supplies and become less dependent on foreign exports. This issue fits in with the latest developments in new investment in wind turbines.

Who knew that something as beautiful as snow could cause so much trouble and provide so much economic analysis!
