Knottingley Power Project
Project Information Note
The Gas Pipeline
Introduction
The CCGT power plant will be fuelled by a supply of natural gas. The supply of natural gas will be taken from a new
underground Gas Pipeline (together with associated infrastructure, principally an Above Ground Installation (AGI)) which will
be constructed between the CCGT power plant site and the National Grid National Gas Transmission System. The new
underground Gas Pipeline will be approximately 8 kilometres (km) in length. The AGI will be constructed at the connection
point to the existing National Grid pipeline.
Description of Gas Pipeline and Above Ground Infrastructure
The proposed route for the Gas Pipeline takes a northerly exit from the CCGT power plant site, running under the Aire and
Calder Navigation Canal and the A645 (Weeland Road). The proposed route then turns north-east and continues on to
Kellington. The proposed route then turns towards the north, but is still heading in a roughly north-east direction. The
proposed route crosses the River Aire, and continues north-east towards the National Transmission System. The
connection to the National Transmission System is made south of Gateforth, off Pale Lane.
The proposed route of the new underground Gas Pipeline is shown in the attached Plan.
The AGI will be an un-manned facility. The AGI will comprise two separate compounds: one compound owned and
operated by National Grid; and, one compound owned and operated by Knottingley Power Limited. Each compound will be
enclosed by a steel security fence approximately 2.7 m high. Furthermore, both compounds will be located within the overall
AGI site enclosed by a stock-proof fence. The equipment within the AGI (with the exception of lighting columns which will be
approximately 4.5 m) will be lower than approximately 2.7 m. The proposed layout for the AGI is shown in the attached Plan.
Proposed Programme
The proposed programme, comprising construction / operation / decommissioning dates, is as follows:
Start of Construction:
2015
Connection to and Commissioning of CCGT Power Plant:
2017
Full Operation of CCGT Power Plant:
2018
Decommissioning:
2043
These dates have been selected to tie in with the proposed dates for the construction / connection and commissioning /
operation and decommissioning of the CCGT power plant. The construction of the Gas Pipeline is expected to take one
year, however two years are allowed such that there is a construction contingency.
Construction
The majority of environmental impacts arising from the development of gas pipelines (and their associated infrastructure)
occur during construction. The construction methods to be used on the KPP Gas Pipeline represent proven methods that
have been developed over many years from experience on similar projects.
All construction activities are undertaken within a temporarily fenced-off strip of land, which is referred to as the "working
width". The working width will typically be 26 to 30 m wide. Access to the “working width” will be at defined points to be

agreed by the Local Planning Authority and Land Owners / Land Occupiers. Points of access will be carefully controlled and
signposted.
During construction of the Gas Pipeline, construction activities will normally be progressed in the following order: preconstruction activities (i.e. fencing, hedgerow removal, land drainage schemes); top-soil stripping; pipe stringing; welding
and joint coating; trenching and laying; commissioning (i.e. cleaning, gauging, testing); and permanent re-instatement.
In addition to the typical construction activities, special teams will be set up to undertake any works associated with “special
crossings” (i.e. road /rail / water crossings). Accordingly, in addition to the more standard ‘open cut’ construction technique,
typical (trenchless) special crossing construction techniques include: auger boring; tunnelling; and, HDD.
Operation
After full commissioning of the Gas Pipeline, it will be operated and maintained in such a manner as to keep it safe and in
good condition. Regular monitoring will be undertaken.
Decommissioning
The Gas Pipeline will be decommissioned when it reaches the end of its useful life. Based on current best practice, it is
likely that the Gas Pipeline will be left in place and stabilised.
Environmental Impact Assessment
The potential environmental impacts of the Gas Pipeline during construction / pre-commissioning / commissioning /
operation / decommissioning have been assessed in relation to the following aspects of the environment: air quality; noise
and vibration; ecology; water resources; geology and soils; landscape and visual; traffic, transport and access; cultural
heritage / archaeology; and, socioeconomics.
Following the implementation of mitigation and monitoring measures, the assessment has indicated that the residual impacts
associated with the Gas Pipeline are considered to be Not Significant.
Safety
Safety is of fundamental importance during every stage of planning, routing, design, construction and subsequent operation
of a high pressure gas pipeline. As such, a number of appropriate safety considerations have been considered to ensure
compliance with the requirements of the Health and Safety Executive (HSE) and ensure safe operation of the Gas Pipeline.
Further information is available in the Preliminary Environmental Information Report.
