  1. UK Gas Statistics Iain MacLeay DECC Energy Statistics May 2011

  2. Contents • Overview of UK gas flows • Production data – admin source • Trade data • Electricity generation • Energy industry use • Final consumption • Secondary and other data • Publication frequency

  3. Key data • Production declining since 2000 • Net import dependency of 38%, but UK still exports 16% of production Use of gas • Generation/domestic/other 36% / 35% / 29% • Responsible for 81% of domestic heating • Accounts for 39% of primary energy supply • 45% of UK electricity generation

  4. Production Trade Stock change Supply Stats difference Demand Transformation Energy industry use Losses Final consumption Industry Domestic Services Non-energy use

  5. Main gas survey PPRS – admin source Other gas surveys Other data EU-ETS data National grid / trade data Survey of electricity generators Survey of auto-producers

  6. UK Production data – PPRS system Petroleum production reporting system • Data collected to allow DECC engineers to monitor operation of UK oil and gas fields • field level – mainly for engineers • terminal level – mainly for statistics • Companies obliged to report monthly – part of licence agreement • Source of UK oil and gas production data, and some trade data

  7. UK Trade data Two sources • From National Grid/Others • LNG – 3 terminals • Pipelines • 3 for imports from Norway • 1 for imports from Netherlands • 1 for exports to Ireland • 1 interconnector with Belgium • Customs data

  8. UK Gas Trade Map

  9. Stocks From National grid Long range – Rough (depleted gas field) Medium – mainly salt caverns Short range – LNG at end of pipelines to maintain pressure Published daily on web site – DECC take monthly data

  10. Main gas survey PPRS – admin source Other gas surveys Other data EU-ETS data National grid / trade data Survey of electricity generators Survey of auto-producers

  11. Gas for electricity generation Survey of main power producers • Used as input for other fuels – so not specifically a gas survey (70 forms on monthly basis, 32 of which have gas data) Survey of auto-producers • Again survey of all fuels – (100 forms on a quarterly basis, 75 report gas) • Heat production data also obtained Secondary survey data • Questions on electricity generation also asked on quarterly gas survey (used for verification)

  12. Energy Industry Use Most data from PPRS admin system re gas use in oil and gas extraction From survey of oil refineries Data from Iron & Steel Statistics Bureau for use in blast furnaces (monthly) Data from National Grid re losses

  13. Final consumption • Survey of main gas suppliers – quarterly for headline data, annual for detailed breakdown – 23 firms account for 95% of gas sales – semi compulsory with new EU legislation • Survey of small gas companies – annual with request for likely sales in coming year – 70 firms - voluntary 25% response

  14. Additional data • Meter point data – 22½ million domestic meters, 300,000 non-domestic meters • EU-ETS – statistical returns supplied to UK Environment Agency • Price surveys • Modelling of effects of temperature on demand

  15. Publication frequency • Supply – monthly • Gas balance – quarterly (no breakdown of industry available, or energy own use) • Full gas balance – annual • Monthly – web • Quarterly/annual – web and paper publication

  16. Summary • Complex picture • Mix of admin data and statistical surveys • Best practice keys: • Choose the right data collection method • Examine secondary data
