Coal-fired Power Stations

Marcus Jones Excerpts

Wednesday 29th June 2011 Westminster Hall

[Mr Mark Spencer (Sherwood) (Con)]

I am pleased to have secured this debate on what I consider one of the most important issues the country faces at the moment. It is also a pleasure to serve for the first time under your chairmanship, Mr Howarth.

I have a number of concerns that require a great deal of attention. Principally, our nation’s ability to ensure energy security is very important. Will we be able to keep the lights on in the future? Many customers and constituents are keen to ensure that the Government are focused on that question. How are we to keep the lights on, without becoming completely reliant on our European neighbours? Although we have a European market and many nearby nations are able to supply electricity, I am concerned about how secure that supply is, and how amiable their taxpayers will be about giving British people electricity when they may run short at the same time.

Throughout history, this nation has been served well by coal-fired power stations. Coal as an energy source to generate electricity is flexible, reliable and dependable. However, there are a number of pressures, such as the requirement to reduce our carbon footprint, that are calling that into question.

[Mr Marcus Jones (Nuneaton) (Con)]

I congratulate my hon. Friend the Member for Sherwood (Mr Spencer) on securing this important debate. Does he agree that it is not just an issue of energy security? There is also an issue in relation to facilities such as Daw Mill colliery in my constituency, where nearly 700 people work. In addition to issues around energy security, should we not be concerned to ensure that we still use the coal that is under our feet in Warwickshire, so that we are not exporting carbon emissions abroad and are supporting UK jobs?

[Mr Spencer]

I will come to that point later. I should put on record that some of my constituents in Nottinghamshire travel to Warwickshire to work at Daw Mill. That we have so much coal under our feet is pertinent, as is the fact that so many constituents rely on the coal industry for employment.

I will start by outlining the current usage and how we generate power. Coal produces more than 35% of the UK’s base load of electricity during an average year. In recent winters, when the weather has been cold, that base load lifted to 50% of the supply generated by coal. That emphasises not only how dependent we are on coal, but how flexible it is, responding to the requirements of the British public. On a cold Christmas day when everyone is trying to cook their turkey at the same time, we need a great deal of flexibility in the supply chain to be able to respond. I want to touch later on the fact that, unfortunately, the wind does not blow harder on Christmas day than on any other day of the year. We need that flexibility to respond to demand.

Fossil fuels as a whole account for 80% of our energy supply: coal being 25%, gas 21% and petroleum 34%. In addition, nuclear provides 6.5%; hydro 2.2%; and biomass waste 11%. Only 0.4% of global energy demand is met by geothermal, solar and wind. Estimates suggest that world demand for coal-fired generation will increase by 70% in the period up to 2030. China is currently constructing the equivalent of two 500 MW coal-fired power stations a week, a capacity comparable to the entire UK power grid each year. Those figures are quite pertinent and put in perspective where the UK fits into a global generation market. About a third of UK electricity is generated from coal but it currently emits more CO₂ per unit of electricity than all other forms of generation. That is something we need to address.

The UK has installed electricity capacity of 77 GW. By 2016, it is expected to face a shortfall of 32 GW, as older coal, nuclear and oil plant is closed down, as demand rises. That is crucial and key to the debate today. Government policy is currently to introduce a floor price for carbon. Many of the coal-fired generators recognise that that is going to put enormous pressure to be economic on their business. In the medium to short term, it will not be possible to secure nuclear power stations that deliver the energy that we require. Generators that produce power via coal are working their units very hard to secure as much return on their investment as possible. There will be a period when our ability to generate power will be short, and the Government need to look long and hard at how we will close that gap.

As my hon. Friend the Member for Nuneaton (Mr Jones) suggested, coal is currently plentiful. It is relatively cheap, flexible and able to respond quickly. We are not prone to outages, and coal is not vulnerable to geopolitical risk. Coal generates about 40% of the world’s electricity, with about 10% each for gas and nuclear. Coal burned by major electricity generators, which account for 80% of total coal use, was up 3% in 2005. Coal burned in UK power stations was 23% higher in the third quarter of 2006 than in the same period in 2005. Coal demand is rising. That demonstrates not only how reliant on coal we are in this country, but the pertinent fact that use is increasing.

UK pits and mines are pretty efficient. We have heard about Daw Mill. Thoresby colliery in my constituency is very efficient in its coal production. I am delighted it has now had permission to explore another seam, which will secure the future of that colliery for at least the next 10 to 12 years.

Given current global energy consumption, it is estimated that there are enough recoverable coal reserves to provide the entire planet with all its energy for the next 600 years, at the current rate of usage. Britain is estimated to have 7 gigatonnes of coal left. In power stations performing carbon capture and storage, we could deliver a sustainable and reliable approach to energy production.
