European market

Britain’s natural gas reserves are decreasing and Britain’s dependence on imported gas is growing.

This means that  it is becoming increasingly important to ensure our interconnectors can provide dependable supplies of gas into Britain. Currently there are three connections between Britain and the EU. These are:

  • BBL (Balgzand Bacton Interconnector from Bacton in Norfolk to the Netherlands)
  • Interconnector UK (from Bacton in Norfolk to Belgium)
  • The Irish Interconnectors (from Moffat in Scotland to Northern Ireland, the Republic of Ireland and the Isle of Man).

In addition to diminishing GB gas supplies, there has been an increasing liberalisation of the internal European gas market through EU legislation collectively called the Third Package.

As a result of the Third Package and other changes in legislation new principles and rules for access to pipeline capacity have needed to be developed and implemented alongside the design of market-based gas balancing regimes and mechanisms to facilitate efficient investment in new infrastructure.

We contribute to these developments in a number of ways including:

  • through involvement in ACER’s (Agency for the Cooperation for Energy Regulators) Gas Regional Initiatives
  • by supporting the development of European Framework Guidelines and Network Codes
  • by contributing to drafting voluntary guidelines of Good Practice within CEER (Council of European Regulators)
  • by ensuring that arrangements in Britain and on our interconnectors are compliant with European legislation and facilitate market integration.
