  • A Brief History of the GB Energy B2C Retail Market – 'The Disruption Of
    22nd Edition November 2020 World Energy Markets Observatory A brief history of the GB energy B2C retail market – ‘the disruption of incumbents’ Over the last 15 years, the GB energy retail market has changed significantly. A look back to 2005 shows 12 suppliers, with the ‘Big 6’ incumbent energy retailers – EDF Energy, British Gas, SSE, Scottish Power, npower (RWE) and E.ON having a market share of effectively 100% of the 30 million customers in the UK.1 Only 15 years later, the market in 2020 looks dramatically million in gas.3 Of these, 22% were customers switching away different - with over 50 suppliers, and the market share of the from the six largest suppliers.4 legacy incumbents’ being reduced to circa 70%. Moreover, suppliers previously thought of as “challengers” or “small Not every new entrant or challenger that has entered the suppliers” have made large acquisitions and/or grown market has been successful. In particular, in 2018 we witnessed significantly. The market is now dominated by Ovo Energy, 14 exits from the market, with Ofgem, the energy regulator, EDF, British Gas, Scottish Power and E.ON. needing to use supply of last resort arrangements for over one million customers.5 Further, a series of acquisitions from Figure 1 provides a chronicle (2005 to 2020) of how the market Octopus Energy (including ENGIE, Co-Operative Energy, structure has changed and how the UK energy retail market Affect Energy and Iresa Energy) have seen their customer base has become one of the most competitive in Europe. The increase to over one million in less than five years.

  • Plantilla IESE Documentos Con Centros
    WP-1205-E August 2018 Powering Côte d'Ivoire. Understanding the Landscape and Exploring Possibilities for Investment LETICIA PELIZAN PAVLAK Research Director, IESE Fuel Freedom Chair SIAM-IZE HERMANN SEDJI Research assistant AHMAD RAHNEMA ALAVI Professor Abstract Back in the ’90s, Côte d’Ivoire was one of the first nations in sub-Saharan Africa (SSA) to turn to independent power producers (IPPs) to meet its rapidly growing demand and to grant a private utility a concession to operate the distribution and transmission network. Thanks to this strategy, its power system is one of the most reliable and extensive in SSA. Aware of the crucial role electrification plays in sustaining economic growth and accelerating social development, the country has made substantial and rapid progress since the end of the post-electoral conflict in 2011. However, the sector still faces many challenges. The electricity consumption per capita is 10 times lower than the world average, and 67% of households, primarily in rural areas, do not have an electricity connection. The tariffs and access fees are too high for a significant part of the population but too low to cover the costs of the system, which creates a financial deficit. With regard to electricity generation, the sector is still has a high concentration of players and technologies. Shortages in the supply of domestic natural gas – the main fuel to generate electricity – represent a threat, and the potential of renewable energies (other than hydro) remains locked. Furthermore, demand is growing fast, putting pressure on the country’s investment capacity, and the outdated network is suffering high commercial and technical losses.

  • Annex 3 - Mock-Up of How the 2018/19 Annual Report Would Look If the Proposed Changes Were Made
    Consultation seeking views on proposed changes to the format of the Renewables Obligation (RO) Annual Report Annex 3 - Mock-up of how the 2018/19 annual report would look if the proposed changes were made The Office of Gas and Electricity Markets 10 South Colonnade, Canary Wharf, London, E14 4PU Tel 020 7901 7000 www.ofgem.gov.uk 0 Renewables Obligation Annual Report (Proposal 2019-20) The Office of Gas and Electricity Markets 10 South Colonnade, Canary Wharf, London, E14 4PU Tel 020 7901 7000 www.ofgem.gov.uk 1 Executive Summary The Renewables Obligation (RO) is a scheme which supports the deployment of large-scale renewable electricity generation in Great Britain (GB), and the deployment of large-scale, as well as smaller scale renewable electricity generation in Northern Ireland (NI), by setting an obligation on licensed electricity suppliers to source a portion of their supply from renewable sources. This report covers scheme activity during the 2018-19 obligation period (1 April 2018 – 31 March 2019). Supplier compliance Overall, suppliers presented 107.64 million Renewables Obligation Certificates (ROCs) towards the total UK obligation of 127.62 million ROCs. Those suppliers not meeting their obligation by presenting ROCs are required to make up the shortfall by making payments into the buy-out fund or the late payment fund. The payments collected resulted in £841.9m being redistributed to eligible suppliers from the combined buy-out fund and late payment fund, exceeding the previous record of £604.1m set in 2017-18. The proportion of the obligation met by suppliers presenting ROCs (84.34%) was slightly lower than the corresponding figure in 2017-18 (87.6%).

  • Thinking About Changing Your Fuel Supplier?
    Thinking about changing your fuel supplier? Switching supplier is a good idea: • It could make your bills cheaper – most people can save around 20% on their energy bills by changing supplier: this could be an extra £245* a year in your pocket. • You may want to buy green electricity. • You may also want to change if you have had problems with your current supplier. Be careful: Suppliers may contact you directly and ask you to switch from your existing supplier and to sign contracts with them. Be cautious of claims made by sales people about the savings you could make. Do not rush into a new contract; you may get a better deal elsewhere. How to choose: 1. Work out how much fuel you use: To find cheaper gas and electricity, you need to know how much (how many kilowatts) gas and electricity you use. The cheapest supplier for you might not be the cheapest supplier for the next person – it depends on how much fuel you use. Use your old bills to add up how much electricity and gas you use in a year. If you don’t have your old bills, phone your supplier and ask them how much you have used in the last year. Write down how much gas and electricity you use in a year here: Electricity used in a year kWh Gas used in a year kWh Last updated November 2020. © Changeworks 2020. *Which? September 2018.
