2 TEES CCPP PROJECT Overview of our proposals The Tees CCPP Project would represent an important step forward in the future development of the Wilton International site on Teesside - one of the UK s most important manufacturing locations. The project is a proposal to design, build and operate a new combined cycle gas turbine (CCGT) power plant on the site of the former Teesside Power Station at the 2,000 acre complex. No decision has yet been taken on whether the development can go ahead. It is subject to planning approval at a national level and internal (Sembcorp) financial and technical consent. However, if approved, the facility could potentially provide the vital power supplies to enable other job creating industrial developments to take place at the Wilton International site. Natural gas would be supplied as a fuel from an existing pipeline to the site linked to the National Transmission System (NTS) at Billingham. The power plant would also be able to utilise Wilton s excellent distribution network to supply power to current and possible future site operators and would be flexible enough to supply surplus power to the public and businesses via the existing National Grid substation connections. Water used for cooling purposes would be taken from existing supplies to the plot and discharged to the River Tees through Wilton s established drainage infrastructure. It would also play a significant role in the battle to secure the UK s energy future by generating up to 1,700 MW of electricity - enough to power up to 1.5 million homes and businesses. Tees CCPP has the potential to create 60 to 80 permanent new jobs and a further 1,000 construction jobs during a 3 year build phase. In addition, it would require the support of hundreds of people in its supply chain over a lifespan of around 30 years. The project requires planning permission and the Planning Inspectorate is the Government agency responsible for operating the planning process for nationally significant infrastructure projects (NSIPs) such as the Tees CCPP Project. WHY ARE WE PROPOSING A GAS FIRED POWER STATION? Security of supply: The UK needs to develop new electricity generating capacity to replace its ageing coal-fired power stations. All coal fired generation in the UK will cease by New generating capacity will help to safeguard the security of electricity supply to the country s homes and businesses as set out in Government policy. Flexible generation: The UK is also increasingly reliant on renewable energy most notably wind power which, by definition, is intermittent in nature being entirely dependent on weather conditions. Gas fired power stations remain an important part of the UK s power generation mix and are able to respond rapidly to fluctuations in supply (e.g. when the wind isn t blowing) in order to ensure enough electricity is generated to meet the national demand. They are also considerably cleaner than power stations using coal or oil and emit significantly lower carbon dioxide emissions per MW than other fossil fuels. The Tees CCPP facility would be capable of generating enough electricity to supply around 1.5 million homes per year - a volume equivalent to around 3 per cent of the UK s current domestic and business electricity consumption. As one of the first new build gas fired power stations to be built in the UK in recent times, the Tees CCPP would bring significant benefit to the UK s electricity supply, adding to the security and flexibility of the distribution network at the same time as contributing to the Government s carbon reduction targets.

3 The proposed development site The new gas-fired station would be built within the boundary of the former 1875MW Teesside Power Station, which operated from 1993 to 2013 prior to its demolition. THE PROPOSED DEVELOPMENT SITE The new gas-fired station would be built within the boundary of the former 1875MW Teesside Power Station, which operated from 1993 to 2013 prior to its demolition. The brownfield location is ideal for future power generation, benefitting from existing electricity grid connections, water supply and roads infrastructure. Local planning policy also recognises the importance of the site for power generation. MAIN SITE The main site comprises 39 acre to the south west of the near 2,000 acre Wilton International site and is outlined in red below. This includes land required for the new power station in addition to associated infrastructure connections and other works. Not all of the land on the site would be built on. Some would only be required on a temporary basis during the construction stage (e.g. for laydown and storage of materials and plant equipment). There is also a requirement on all new build gas fired developments to be Carbon Capture Ready meaning we need to reserve around 10 acres of land within the main site to accommodate potential future carbon capture facilities if and when the technology is both viable and technically feasible. LAND REQUIRED FOR THE PROJECT The new power station would be sited within the area of land owned by Sembcorp Utilities (UK) Ltd. No additional land is required from third parties.

4 What is a Combined Cycle Power Plant? The new power station would employ combined cycle gas turbine (CCGT) technology. ELECTRICITY NATURAL GAS CONDENSER In a CCGT power station natural gas is fired into the combustion system to drive a gas turbine (GT) which is connected to a generator to produce electricity. The hot exhaust gases generated by the GT are then passed through to a waste heat recovery steam generator (HRSG) a boiler which recovers more of the heat. The HRSG generates steam which is used to produce further electricity via a steam turbine (ST). The steam leaving the ST is then condensed and this water is returned to the process for reuse. A cooling system is required to condense the steam used in the generation process and this cooling water supply already exists on the plot. STEAM TURBINE GENERATOR AIR WATER AIR COOLING WATER IN STEAM OUT COOLING TECHNOLOGY CONDENSED WATER HEAT RECOVERY BOILER COOLING WATER OUT EMISSIONS TO ATMOSPHERE The electrical efficiency of a modern CCGT power station, dependent on technology selection, can be greater than 60 per cent. This is considerably higher than conventional coal or oil fired power stations, which generate at an efficiency of around per cent. GAS TURBINE EXHAUST GASES

5 Design and Layout options A number of international firms have approached Sembcorp to manufacture the turbines to the design required and a single, successful bidder would be appointed if the plant receives planning approval from the Government and sign off by Sembcorp at a corporate level. Detailed design will start after the consultation. ADDRESSING ENVIRONMENTAL CONCERNS Sembcorp recognises that people might have specific environmental concerns and would seek to address these at the design stage in an attempt to mitigate any impact. As part of its submission to the Government, the company is required to carry out a full assessment of the possible environmental impacts of constructing and operating a power station on the site. Visual Impact Dependent on market conditions at the time of construction, two development scenarios are envisaged: one in which the full 1,700 MWe is built (i.e. two units of 850 MWe each) and a second scenario where one unit of 850 MWe is built and up to five years after the start of commercial operation of the first unit, construction of the second unit commences. THE PROCESS Only the two stacks would be visible from most residential vantage points and both would be positioned furthest away from residential areas. The height of the two stacks would be no more than 75 metres lower than the nearest stacks on the site. The height of the stacks is dictated by the need to disperse the exhaust gases safely and in line with UK environmental requirements. As a project which, due to its size, is deemed a Nationally Significant Infrastructure Project (NSIP) Tees CCPP must be approved by the Secretary of State for Business, Energy and Industrial Strategy. Noise The UK Planning Inspectorate acts on behalf of the Secretary of State in progressing the application, known as a Development Consent Order (DCO). The units would not be open to the atmosphere as previously. Each of the gas turbines would be within a building and each would be within its own acoustic enclosure within the building. In addition, the hybrid cooling technology has been selected as meeting Best Available Technology (BAT) in terms of minimising noise and visual impact. In preparing its environmental assessment, Sembcorp has utilised the modelling services of GT Acoustics, a Guisborough- based noise and vibration specialist with more than 30 years of experience of monitoring noise data across the Wilton International site. Steam The hybrid water cooling tower technology selected is regarded as BAT in relation to plume abatement and the positioning of the units to the north of the site will mean they are furthest away from residential areas and towards the main body of the site. The two exhaust stacks will produce minimal visible plume. Traffic The project both during construction and operation would be accessed from the A1053 Greystones Road. At the peak of construction we would anticipate around 68 lorry movements both in and out of the site per day during daytime hours. Once operational the plant will employ permanent staff and we would envisage no more than 39 movements in and out of the site per day on a normal day. The A1053 is able to cope with these volumes of traffic. Ecology The site has been assessed by local ecology specialists (INCA) and is ecologically benign, meaning that there will be no loss of habitat or bio-diversity during construction or operation of the installation. Air Emissions The process will be designed to meet the latest emissions limits as defined by the Environment Agency. Due to the use of natural gas as a fuel and the proposed efficiency of the installation, initial phase air emissions modelling indicates that there will be no significant impact from carbon monoxide, oxides of nitrogen or sulphur dioxide. As part of the DCO application, the applicant (Sembcorp) must demonstrate that it has consulted widely with all stakeholders, including the communities around the site. It is also required to demonstrate how it has taken into account the written responses received in deciding the final form of the development. This event is part of that consultation. Full details of the process can be found on the Planning Inspectorate website: gov.uk/application-process/the-process/ The process also requires the applicant to have carried out a full Environmental Assessment including having prepared an Environmental Impact Assessment in line with UK and EU requirements. Sembcorp has engaged a specialist firm - Environmental Resources Management (ERM) to help us do this. ERM has also sought support from other specialist organisations. The views of the public and other stakeholders are taken into consideration by the Government as part of the planning process and this is therefore your chance to give us your feedback. The representatives present will explain the ways this can be done and how the information will be used. THANK YOU FOR TAKING THE TIME TO ATTEND THIS EVENT TODAY.
