3.12 Once production commences infrastructure is required to feed the gas into the mainstream energy supply. The two main options are (i) additional pipelines to connect into the main UK gas pipeline network and (ii) on site electricity generation which is then connected into the national grid. Under either approach a substantial body of additional labour and equipment is required to put in place the necessary infrastructure, which will grow in scale as the number of wells in any one location increases. It may well be the case that in Lancashire a hybrid solution is put in place which combines gas pipelines at some wells and electricity generation at others.
