5. Energy Transmission and Distribution Network<br />

The following section describes the existing energy transmission and distribution system<br />

present in <strong>Bradford</strong> district.<br />

5.1 Gas<br />

National Grid owns and operates the high pressure gas transmission system in UK that<br />

consists of approximately 4,300 miles of pipelines and 26 compressor stations connecting to<br />

eight distribution networks.<br />

Similar in structure to the electricity industry, gas is distributed nationally via the high the<br />

pressure National Transmission System (operated by National Grid Transmission) to a<br />

series of <strong>Local</strong> Distribution Zones (LDZs), which are based on the former British Gas<br />

regions. The LDZs are operated by Gas Distribution Operators (DOs). The gas supply<br />

companies pay National Grid Transmission and the DOs a tariff for the use of the gas<br />

networks for access to their end-customers. The tariffs are set over 5-year control periods<br />

based on approved investment plans agreed with OFGEM.<br />
