British Gas sees profits up 24% BBC: 24 February 2011 Operating profits at British Gas rose 24% in 2010 to £742m, its parent company Centrica has said. The news comes two months after the UK utility announced a 7% rise in domestic energy bills, which it blamed on rising wholesale prices. British Gas said it had increased its number of customers by 267,000 during the year to 16 million.

The results helped Centrica to achieve pre-tax profits of £2.8bn, with operating profits up 29% to £2.4bn. 'Bitter pill' The 24% rise in British Gas's operating profit was largely because of an increase in profit per customer, with the number of customers up just 1.7%, as revealed in the group results of its parent Centrica. Some 85% of British Gas's profit came in the first half of last year, according to a Centrica spokesperson, when customers increased energy usage in response to cold weather, and the firm attracted new business with a price cut in February. The second half was less profitable for the group's residential energy unit as wholesale prices rose more quickly. Centrica has claimed the decision in November to increase British Gas customers' energy bills was necessitated by a 67% rise in wholesale gas prices during the year, and a 29% rise in the cost of wholesale electricity prices.

Price comparison website Moneysupermarket.com called the rise in British Gas's profits a "real bitter pill to swallow for Britain's hard-pressed households who have suffered the double whammy of an extremely cold winter coupled with high gas and electricity prices". British Gas launched what the comparison website considered the cheapest online tariff on the market in February. But Moneysupermarket's Scott Byrom said that "customers shouldn't be fooled" into thinking British Gas was the cheapest provider overall because its standard, and most popular tariff, was still much more expensive. Ofgem investigation "British Gas is the only major UK energy supplier that breaks down its results in any great detail," notes Mike O'Connor, chief executive of Consumer Focus.

"As such it acts as a lightning rod for the industry." Amid allegations that energy suppliers were making excessive profits, government watchdog Ofgem announced a review of the retail energy market in November, that is expected to be published at the end of March. "The issue is not about one company or one year's profit or loss but it is about whether the energy market is working properly and Ofgem's review must try to answer this question once and for all," said Mr O'Connor. "There is a compelling case for much more transparency across the market." Upstream growth Centrica comprises a lot more than just British

Gas, including business energy supplies and power generation, as well as substantial operations in North America.

Indeed, its UK residential energy supply unit contributes just 37% of the energy group's revenues. Operating profits at Centrica's upstream business - which deals with power generation and oil and gas drilling, among others - were up 46% to £771m. The company has been expanding quickly, according to chief executive Sam Laidlaw, with two major acquisitions last year designed to secure new sources of gas, and to expand into nuclear energy. "We invested £4bn," he said. "Clearly therefore we have a much bigger group [than just British Gas]. We've been investing £1.60 for every £1 of profit for the group." Ofgem to probe Scottish Power price rise promotion BBC 22 June 2011 Energy watchdog Ofgem has launched an inquiry into a "potentially misleading" offer promoted by Scottish Power after it announced 19% price rises. The firm had guaranteed prices would remain a minimum of 1% per year below its standard monthly direct debit prices until 30 September, 2012. But Ofgem insisted the small print did not match up to the promise. Scottish Power said: "We believe that all figures that have been quoted by us are accurate." The regulator said it also wanted to press ahead with radical market reforms and force the so-called "big six" energy suppliers to simplify tariffs.

British Gas, Npower, E.ON Energy, EDF Energy, Scottish Power and Scottish and Southern Energy have all signed up to the reform process. Ofgem said it would be using its consumer protection powers to investigate the promotional offer which was announced by Scottish Power when it revealed it would be putting up prices in August. The watchdog outlined that the investigation would focus on the claim of £459 savings from the Direct October 2012 offer. The increases, which will see the cost of gas go up by 19% and the cost of electricity by 10%, will affect some 2.4 million householders in the UK. Scottish Power had blamed a 30% rise in wholesale gas costs for the increases.

In response to the launch of the inquiry, the utility company said: "We agree that information about all energy tariffs across the market should be as clear as possible and we will fully co-operate with the Ofgem investigation."The tariff in question was a very limited offer with considerably discounted prices, which is now fully subscribed. "However, there are a number of similar products still available on the market from competitors. We believe that all figures that have been quoted by us are accurate. " Consumer Focus said it welcomed Ofgem's announcement and added that the utilities market needed to change. The body's chief executive, Mike O'Connor, said: "The fact that Scottish Power was trying to push a dubious product to cover for their price rise shows just how far the penny needs to drop. "Energy suppliers have been in denial

about their poor reputation, about the health of the market and about the scale of changes needed to put it right. This market needs to change. "Ofgem has taken another step today and we welcome it." Meanwhile it was confirmed the six energy suppliers will be questioned by the Scottish Parliament's economy committee next week. Committee convener and Tory MSP Gavin Brown said he wanted to hear the justification for price rises, adding: "It is important the committee is convinced that the suppliers and the regulator are doing all that they can to minimise the impact of these price rises on low income families and not to prejudice a return to economic growth." Gas and electricity prices: How are they calculated?

BBC:17 November 2010 Money Talk by Ben Essex Lead energy analyst at ICIS Heren Energy prices are going up. Both British Gas and Scottish and Southern Energy (SSE) are putting up gas tariffs in December, and other major energy providers may follow suit soon. The companies have blamed a 25% increase in wholesale costs this year. But have wholesale prices gone up? And how does the wholesale price relate to the figure that appears on your energy bill? Is blaming the wholesale price justified? Wholesale prices With other costs to supply energy relatively fixed and constituting a small part of your overall energy bill, energy suppliers almost always cite wholesale prices as the reason behind a change in their tariffs. But at any one time there are many different wholesale prices, so to say they have gone up by 25% is meaningless. All of these wholesale prices have in fact gone up over the period quoted by SSE and British Gas. But anyone who knows anything about the energy market also knows that a wholesale price movement can be found to support pretty much any retail energy price change - whether up, down, big or small.

So, how does the wholesale market work? Before gas and electricity gets into your home, it is first sold to the energy suppliers. In the UK, some of the big household suppliers produce or generate a proportion of their own energy. But they buy most of it either direct from the producers who generated the power or sourced the gas, and the rest is bought from the traded wholesale markets. In either of these scenarios, the UK suppliers are usually paying the price set by the traded market, where a variety of producers, utilities and speculators are active every day.

Each energy supply company will have a small team of energy traders and analysts in their central office trading and monitoring price movements in the gas and electricity markets throughout each day. These energy traders are not dealing with a singular wholesale gas or electricity product - but a myriad of gas and electricity "contracts" which are defined by the period within which the energy is to be delivered. So, as an energy trader, today I can buy energy for today. And that energy will be priced differently to gas or

electricity which I buy for delivery tomorrow. Both of these prices will be different to energy priced for delivery this weekend, next week, next month, next year, or even in five years' time.

Further complications arise because contract prices can change every second, as sometimes hundreds of trades are made on the same contract each day. So the difference in price between contracts, and even for the same contract over the course of the day, leads to numerous wholesale prices. The traded price of a gas or electricity contract on the wholesale market will be defined by multiple factors, including supply and demand. Near-term price changes are often driven by immediate factors, such as weather forecasts affecting energy needs next week. Longer-term prices tend to be influenced more by macroeconomic factors, like oil prices and broader economic conditions.

Suppliers purchase energy over varying periods, spreading their purchases across many points in time to manage risk associated with market volatility. They buy and resell energy continuously to secure the best prices, which complicates the calculation of a single wholesale price. This trading strategy means suppliers may end up paying very different prices for their energy supplies, depending on their timing and negotiation efficiency. For example, a supplier that bought gas for delivery in late 2010 back in July 2008 would have paid over 100 pence per therm (p/th), whereas the same contract in spring 2010 might have cost less than 40p/th. This wide range illustrates the complexity of wholesale pricing and why a simple percentage increase figure can be misleading.

Since market liberalisation in the 1990s, six major energy suppliers have dominated the UK market—British Gas, E.ON, EDF Energy, Npower, Scottish and Southern Energy, and Scottish Power—controlling about 99% of household supply. Despite claims of competition, the firms often adjust prices in unison, raising questions about the true level of competitive pressure. Regulatory investigations, including those by Ofgem, have affirmed that the market remains competitive, but the shared pricing behaviors suggest a degree of collusion or at least a synchronized response to market conditions.

Ultimately, the nature of energy price setting revolves around the pursuit of profit maximization by suppliers. When one provider adjusts its tariffs, it influences other providers' strategies due to competitive dynamics, often resulting in simultaneous price movements. Consumers are encouraged to respond to these signals by switching suppliers regularly, fostering competition and preventing collusive pricing behavior.

Paper For Above instruction

In the context of the UK's energy market, competition levels are a crucial aspect affecting consumer

welfare, pricing strategies, and market efficiency. The industry is characterized by a handful of dominant players, known collectively as the 'Big Six,' which control nearly all residential energy supply. Analyzing the competitive landscape and applying theoretical market models provides insights into whether this oligopolistic structure fosters perfect competition or exhibits features of market concentration and collusion.

Assessment of the UK's consumer energy market indicates a high concentration ratio, with these major firms exerting considerable influence over pricing and supply. According to the Herfindahl-Hirschman Index (HHI), the market exhibits a high level of concentration, aligning closely with an oligopolistic market structure as per the Cournot model. Under the Cournot framework, firms compete strategically by choosing quantities, which impacts market prices and consumer choices. Given the uniformity in pricing behavior and the synchronized adjustments following cost changes, the UK energy market most resembles this model, where firms have significant market power and operate in a strategic rather than perfectly competitive manner.

The actual degree of competition is further nuanced by factors such as market entry barriers, regulatory oversight, and product differentiation. Although liberalized, the market's structure deters new entrants owing to high capital costs and regulatory hurdles, reinforcing the oligopoly. Furthermore, the differentiated nature of tariffs and the complexity of billing mechanisms reduce direct price competition among providers. Surveys and regulatory reports, including those from Ofgem, demonstrate that despite claims of competition, pricing strategies tend to mirror each other, indicating limited true competition and potential tacit collusion among firms.

In the context of theoretical models, the UK's energy market does not conform strictly to perfect competition, characterized by numerous small firms and free entry. Instead, it aligns more closely with models of oligopoly, such as Cournot or Bertrand, where strategic interdependence and barriers to entry shape market outcomes. The Cournot model recommended here emphasizes quantity competition, which, in this case, translates into coordinated pricing behaviors and profit maximization strategies that minimize price wars, contrary to a purely competitive environment. The observed synchronized tariffs, price increases, and resistance to penetration by smaller firms confirm this alignment.

Price competition within this oligopolistic structure is often evident through the frequent, large-scale tariff adjustments by incumbent firms. These moves are typically responses to changing wholesale costs,

regulatory interventions, and strategic considerations aimed at maintaining profitability without provoking a price war that could erode margins. While some prices temporarily decrease to attract customers, the overall trend in the industry remains upward, reflecting the limited effectiveness of price competition and the influence of market power.

Evaluation of how price competition affects the degree of market competition reveals mixed effects. On one hand, consumers benefit from increased options and the potential for switching to cheaper tariffs, which exerts downward pressure on prices. Conversely, the high degree of market concentration limits the overall competitive effectiveness, allowing firms to coordinate or follow common industry-wide pricing strategies, thereby maintaining higher price levels. Regulatory reforms by Ofgem aim to foster greater transparency and potentially stimulate real competition; however, actual market behaviors suggest that the degree of competition remains constrained by structural factors and strategic collusion.

Moreover, the existence of complex tariff structures and promotional offers complicates consumer choice, often leading to consumer inertia and reduced switching rates. This inertia diminishes the competitive pressure on firms to lower prices sincerely, further entrenching the oligopoly. To enhance competition, policymakers advocate for simplifying tariffs, increasing transparency, and encouraging consumer switching, which would force firms to compete more aggressively on price and service quality.

In conclusion, the UK energy market demonstrates characteristics typical of an oligopoly, with features aligning most closely with the Cournot model of strategic quantity competition. Despite regulatory efforts to promote genuine competition, high market concentration, product differentiation, and strategic price-setting behaviors limit the true level of competitive pressure, suggesting that consumers currently face limited choices and relatively high prices. Effective market reforms and increased consumer engagement are essential to transitioning toward a more competitive landscape, thereby benefiting consumers and promoting efficient market functioning.
