Site Location & Description
The Project Site is located near to the Port of Immingham in an industrial area. Immingham Dock is located approximately 1.5 km to the south east at its closest point. The Humber ports facility is located approximately 500 m north and the Humber Refinery approximately 500 m to the south. The nearest town is Immingham, located approximately 2.5 km south east and the nearest residential property is a single property on Marsh Lane located approximately 325 m to the south east at its closest point. The villages of South and North Killingholme are located approximately 1.4 and 1.6 km west, south west.
The current boundary of the Project Site (red line) is shown in the plan below. At this stage, this is indicative and subject to change.
The proposed OCGT power station would be located within the most northern part of the Project Site on open land immediately to the north of the existing VPI Immingham Combined Heat and Power (‘CHP’) Plant on Rosper Road. The Project Site also includes land required for a new gas supply pipeline and electrical connection works, along with land required for temporary construction laydown and an existing gas pipeline that connects to the National Transmission System (‘NTS’) (No. 9 Feeder pipeline).
The land proposed for the new OCGT power station, known as the ‘Main OCGT Power Station Site’, covers an area of approximately 2 hectares.
The Need for the Project
The UK needs new energy infrastructure to maintain diversity and security of energy supplies. A significant proportion of the UK’s generating capacity, including coal-fired plants, are required to close over the next decade. The need for the development of new power stations, including gas-fired power stations is set out in government policy. This policy includes the Overarching National Policy Statement for Energy (‘EN-1’) and the National Policy Statement for Fossil Fuel Electricity Generating Infrastructure (‘EN-2’). These documents can be found here.
The UK is increasingly reliant on renewable energy, primarily wind energy, in nature and dependent on weather condition. Gas-fired power stations provide flexibility within the UK’s generation mix, being able to respond rapidly to fluctuations in supply (e.g. when the wind isn’t blowing) and ensure that enough electricity is generated. Gas-fired power stations are also cleaner than those using coal or oil and emit significantly lower CO2 emissions per MW than other fossil fuels.
The Project would make a significant contribution to UK electricity supply in terms of both security and flexibility while contributing to the Government’s carbon reduction targets.
What is an OCGT?
An Open Cycle Gas Turbine (‘OCGT’) uses compressed gas to fire a turbine to generate electricity. OCGT has the ability to start up and take up a significant electrical load quickly, making them useful for peak load applications.
Main components of the Project
The Project comprises the construction and operation of a new gas-fired power station of up to 299 megawatts (‘MW’) gross output and associated development.
The main components of the Project are as follows:
- a single OCGT unit comprising a gas turbine, electrical generator, a stack and main transformer;
- switchyard, associated switch gear and ancillary equipment;
- gas receiving area, gas treatment control facilities, gas reception building and gas pipeline to a new Above Ground Installation;
- electrical connection with a potential upgrade of switchgear or other existing equipment;
- water supplies and pipelines;
- auxiliary generator and liquid fuel tank for emergency electrical supplies;
- lubricating oil, hydraulic oil and chemical storage tanks and equipment
- workshops and stores;
- electrical, control, administration and welfare buildings;
- above ground raw water and fire water storage tanks;
- storm water attenuation system or similar;
- internal access roads and car parking;
- landscaping and fencing;
- auxiliary cooling equipment/ system and cooling water supply; and
- other minor infrastructure and auxiliaries/services.
It is envisaged that the construction of the Project would take up to 3 years to complete and would give rise to traffic movements from the delivery of construction components and materials, removal of waste and travel to and from the Project Site by the construction workforce. There would also be a small number of abnormal loads required for larger construction components, such as the gas turbine. A Construction Environmental Management Plan, including a travel plan, would be agreed with the local planning authority prior to the construction phase to minimise construction impacts.
The Benefits of the Project
The key benefits of the Project are as follows:
- it would respond to the urgent need for new electricity generating capacity in the UK in line with government policy (it could be operational by 2023);
- an OCGT enables the power station to respond rapidly to short-term increases in demand on the electricity transmission system;
- it could provide support where there is a shortfall in renewable energy on the grid;
- it would make use of land within an industrial location that benefits from proximity to gas and electricity connections and good road access; and
- it would have benefits for the local economy during its construction and operational phase in terms of high-quality job creation and supply chain opportunities.
