• 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

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

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)
UK Gas Statistics
Iain MacLeay May 2011
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
UK Gas Statistics
Iain MacLeay May 2011
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

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