Good morning everybodyThis section of the event is going to provide a brief context of the energy market in the UK and provide an introduction to some of the topics to be covered by our speakers in the next session – this may be covering familiar ground for you, but will hopefully serve as a useful refresher.In terms of an agenda:We’ll look briefly at the energy process from generation through to sales;Then we’ll look at the current split between generation methods, establishing where our current supplies are coming from;We’ll touch briefly on sustainability and emissions (but will not go into too much detail as I know this is a topic some of our speakers will want to comment on);and then finally, we’ll look at some headline points concerning each generation methodThere will also be an opportunity for you to have your say and we’ll be asking you to vote on a series of questions relating to energy generation in this session – and you should have in your packs a voting card with one side coloured green for a “yes” answer and one side coloured red for a “no” answer.
OK, so turning to GENERATION,Most electricity is generated at power stations connected to the national transmission network. However, electricity can also be generated in smaller scale power stations which are connected to the regional distribution networks. The number and type of power stations built are the decision of each individual company based on market signals and government policy at the time. It’s important to note at this point that electricity cannot be stored - it is used as it is generated or it is lost.A further essential point to appreciate is that demand for electricity is not constant – demand varies significantly through the day,the week and seasonally.Therefore the system has to be in a position where it can react almost immediately to changes in demand. Not all electricity generating systems are able to react quickly. For example Nuclear is either on or its off and wind power can only generate in the correct weather conditions. On the other hand, coal and gas can react quickly and are used to meet demand over and above base needs. This all goes to highlight that a diverse and flexible fuel mix is essential in the UK.Turning to TRANSMISSION and DISTRIBUTION:There are two types of electricity network: transmission and distribution. Transmission networks carry electricity long distances around the country at high voltages. Distribution networks run at lower voltages and take electricity from the transmission system into homes and businesses.The transmission system is run by National Grid, which is responsible for balancing the system and making sure that the supply of electricity meets the demand on a second-by-second basis. Similar infrastructure exists for the transmission and distribution of gas.In relation to SUPPLY and SALES:96% of the UK’s electricity is generated by 6 companies (who you will have seen featured in the news recently) – the ownership of the Big 6 as they have become known rests in four countries: the UK, Germany, France and Spain.No doubt we will be dealing with questions about the operation of the big 6 later in the morning, so we won’t go into too much detail in this session.Finally, there is the issue of REGULATION:The electricity and gas markets are regulated by the Gas and Electricity Markets Authority, operating through the Office of Gas and Electricity Markets (Ofgem). Ofgem's role is to protect the interest of consumers by promoting competition where appropriate, and Ofgem issues companies with licences to carry out activities in the electricity and gas sectors, it sets the levels of return which the monopoly networks companies can make, and decides on changes to market rules.
In the UK energy is generated in a number of different ways. As we noted, it is important to have a mix of fuel sources and technologies so that there is not an over reliance on one particular form of generation.The main fuel source used in the UK is FOSSIL FUELS, mainly coal and natural gas. As of today, Coal is accounting for 38% of generation and natural gas is accounting for 28%.Second in generation capacity to fossil fuels is NUCLEAR, accounting for 18% of demand, and whilst the programme for closing down historic nuclear power stations continues, the Government has significant plans for nuclear power and has announced its intention to build a new £16bn plant at Hinckley (with the investment from France and China).RENEWABLES:Renewable Fuel sources include wind, wave, marine, hydro, biomass and solar. Renewablesmade up 7% of electricity generated in 2010 and has grown to 13% in 2013 - this is expected to rise as the UK aims to meet its EU target of generating 30% of its electricity from renewable sources by 2020.Finally, it is worth mentioning briefly the energy which the UK IMPORTS.The UK electricity network is connected to systems in France and Ireland, and the UK uses these to import or export electricity when it is most economical, and in 2010, the UK imported just under 1% of its energy
OK, now turning to the issue of SUSTAINABILITY:The energy industry is an important player in the UK economy. Between 2008 and 2010, £17 billion was invested in theUK economy and 45,000 new jobs were created in the energy sector.The issue of CARBON EMISSIONS is at the forefront of energy generation in the UK, and energy companies are committed to cutting their carbon emissions and have pledged to become carbon neutral by 2050.These commitments will help to meet the UK's climate change targets, but a large amount of investment in new, low carbon power stations will also be needed. Emissions from the electricity sector have fallen by 16% since 1990 and are expected to continue to fall. By 2020, zero carbon technologies are expected to produce 40% of our electricity.
GREEN = OK, so there is a majority in favour of committing to reducing emissionsRED = OK, so there is a majority against reducing emissions until other countries commit at the same levels as the UKSPLIT = OK, so there is mixed opinion as to whether we should be reducing emissions until other countries commit at the same level as the UK
WE ARE NOW GOING TO TAKE A VERY QUICK LOOK AT SOME HEADLINE ISSUES ON THE VARIOUS TYPES OF ENERGY PRODUCTION IN THE UK, STARTING WITH COAL.With regard to supply, Coal accounted for 38% of electricity generation in the UK in 2012 - this is up from 29% in 2011, primarily as the price of coal was more stable in relation to gas.Presently, around 41% of electricity in the UK comes from coal-burning power stations. However, a third of these power stations are expected to close by 2016 so that they meet EU air quality legislation. This means that the UK will become less reliant on coal as a source of energy and will need to look at alternative energy sources.In terms of our export and import mix, the UK import more than twice the amount of coal we mine in the UK, and around 7.1 billion tonnes of coal were used worldwide last year, and since 2000, global coal consumption has grown faster than any other fuel.So as to address environmental issues, a new technology called Carbon Capture and Storage (CCS) is being developed to remove carbon dioxide from power station emissions and store it underground - the Government has announced £1bnof funding will be made available for the first CCS demonstration project.
GREEN = OK, so there is a majority in favour of continuing to use coal as part of the energy mixRED = OK, so there is a majority in favour of taking coal out of the UK energy mixSPLIT = OK, so there is mixed opinion as to whether we should be taking coal out of the UK energy mix
OK, now turning to look at headline points concerning OIL and GAS generation.The UK obtains its gas from three main sources: North and Irish Sea, pipelines from continental Europe and Norway, and by shipments of Liquefied Natural Gas from around the world.Gas from fields in the North and Irish Sea typically provide around 40% of gas supplies. However production from these fields is now in decline and the UK is importing increasing amounts of gas from abroad.With regard to price, gas is currently costing twice as much as coal, and the issue of security of supply is likely to affect the price further.Storage is an import issue when considering gas generation. Currently, the UK has over 4billion cubic metres of storage capacity that can be called upon to deliver over one quarter of national gas demand on any day. With regard to employment, over 400,000 people are employed in the oil and gas industry in the UK, which is obviously a major national employer.
GREEN = OK, so there is a majority in favour of continuing to focus on oil and gas as part of a long term energy solution for the UKRED = OK, so there is a majority against oil and gas forming any long term energy solution for the UKSPLIT = OK, so there is mixed opinion as to whether oil and gas should form part of the long term energy solution for the UK
Supply: Around 20% of UK energy is being generated by nuclear power, across 19 reactors located on 10 different sites £930bn worldwide investment in nuclear powerEmployment: 40,000Risk / SafetyNew nuclear plant at Hinckley – will cost around £14bn, to be operational in 2023 and to have a life of 60 years.
GREEN = OK, so there is a majority in favour of Government’s plans to have 25% of energy generation from nuclear sourcesRED = OK, so there is a majority against nuclear playing a significant part of energy generation in the UKSPLIT = OK, so there is mixed opinion as to whether nuclear should form 25% of the UK’s energy requirement
The UK’s location, with shallow seas and strong winds, makes offshore wind an ideal technology for generating power and an important part of the mix helping Britain to meet its 2020 renewable energy target. OFFSHOREOffshore wind also supports a UK supply chain and exports expertise all over the world. During construction over 75 organisations with 6700 individuals were involved. The EMR delivery plan shows that offshore wind has the potential to deliver 16GW by 2020 and up to 39GW by 2030The UK is the world leader in offshore wind, and is likely to remain as such until 2020One of the key factors in the development of UK Offshore Wind will be bringing down cost of the technologyLatest large projects include the London Array, with a 630MW capacity and a 1.9bn investment. DONG Energy, E.On and Masdar have built the world’s largest offshore wind farmONSHOREPlagued by planning objections and contentious with the public Recent large projects include Tallentire Wind Farm nr Cockermouth with a capacity of 12MW, costing 2.1MWind farms dent house prices (Daily Telegraph, October 31, 2013)Britain can't afford to throw money at wind power (Sunday Telegraph June 30, 2013)Currently 4,000 jobs in sector, expected to grow to 30,000 by 2020.

Bentley– The UKs largest rooftop solar PV array was completed. It creates a 5MW installation that can supply 40% of Bentley’s power requirement at peak times.Bridge creates 1.1MW at a cost of 7.3M, but will supply 50% of Blackfriars station’s energy needs.Solar PV has a number of advantages;• Versatile and scalable – can be developed in a wide range of locations including domestic and commercial buildings• Can be developed and installed very quickly• Sun is free!Key to the increase will be the reduction in costs and perhaps consistency in schemes such as FITS. Current capacity is 2.4GW with potential for 7-20GW by 2020.Accounts for about 3% of renewable electricity generation, with the majority being used in domestic applications Recent large schemes include Bentley Motor factory and the world’s largest solar bridge was created across the ThamesIn the Roadmap 2012 (DECC) solar PV was included as one of the key renewable energy technologies that can help to create a balanced UK energy mix. Solar farms are a shining example of renewable energy (The Journal October 30, 2013)
