  1. The use of client files of energy companies Statistical method for monitoring energy consumption in service sectors and households Hans Pouwelse Statistics Netherlands jpwe@cbs.nl October 24, 2012

  2. Content • background • use of client files as alternative • steps forward • results • concluding remarks Statistics Netherlands

  3. BackgroundSituation energy statistics in the Netherlands in 2005 Positive: energy production sector and manufacturing industries (‘the heavy users’) • solid production process, based on surveys, high response rates, intensive contact with key companies • statistical results of good quality and timeliness • results basis for energy balance sheets Statistics Netherlands

  4. BackgroundSituation energy statistics in the Netherlands in 2005 Negative: Other sectors (households, service sectors, etc. ) • response rates, quality response and statistical results poor and decreasing • irregular statistical coverage, only once every 3 to 5 years • poor quality external information (households, agriculture) • lack of finance and staff capacity to improve the shortcomings with traditional questionnairesBut: • increasing demand Statistics Netherlands

  5. Promising alternative ask energy companies for their files with individual client information The idea is simple: • Energy companies have all the necessary information they need to send bills to their individual clients, including the supplied amounts of energy- 8 mln electricity connections- 7 mln gas connections • Collecting this individual client information is much more efficient and less costly than asking many individual consumers Statistics Netherlands

  6. Advantages • Only a limited number of respondents have to be bothered (general policy in the Netherlands to minimize the response burden) • Less costly and more efficient • Increasing quality statistical results (An important source of errors can be avoided: energy consumers no longer have to identify their electricity and gas consumption on annual basis from the information they receive from their energy supplier) • Data on energy consumption can be published for each economic activity (NACE-code) and households annually Statistics Netherlands

  7. Steps forward (1)Legal obligation • Energy companies will not cooperate on a voluntary basis • Legal obligation is necessary • Realised in 2004 as modification of the Dutch statistical law Statistics Netherlands

  8. Steps forward (2)which companies: energy suppliers or network operators? • Energy suppliers:- more information (quantities, prices, costs, taxes)- more and varying number of companies- varying number of clients/connections per company (switching allowed) • Network operators:- only quantities electricity and natural gas- only few and stable number of companies (14, all both electricity and gas)- stable number of clients/connections Choice: Network operators Statistics Netherlands

  9. Steps forward (3)Identify type of client: house hold or business? and type of business (NACE code)? • Records contain address data • Linking to other data:- home register (7 mln dwellings)- general business register (1 mln records)- other administrative data(register real estate appraisal, Dutch land use register, GIS-techniques and others) • Amount of energy Statistics Netherlands

  10. Steps forward (3)Many problems had to be solved: • house number extension (standardisation) • district heating, central heating bloc of flats • combined dwellings/business (one connection) • multiple connections per company (establishments) • multiple companies per connection (office building hired by several companies, one connection) • And many others!

  17. Results Households • Regular statistics production electricity and gas consumption since 2008 (information from statistical period 2004) • Broken down by region (municipal level) • Broken down by housing types and household characteristics (by matching with microdata home characteristics and household characteristics) • Microdata available for external researchers Statistics Netherlands

  23. Results Service sectors • First results published in May this year (statistical period 2010); 2011 by the end of this year • Separate table, integration into Dutch Energy Balance follows as soon as possible • Break down by region as far as possible (confidentiality) Statistics Netherlands

  24. Natural gas and electricity supplies to service sectors 2010 Statistics Netherlands

  25. Electricity consumption in the services sectors (%) Wholesale and retail trade Transportation and storage Public administration and defense Accommodationand food service activities Human health and social work activities Information and communication Financial and insurance activities Real estate activities Other service activities Statistics Netherlands

  26. Gas consumption in the services sectors (%) Wholesale and retail trade Human health and social work activities Public administration and defense Accommodation and food service activities Education Real estate activities Transportation and storage Arts and recreation Other service activities Statistics Netherlands

  27. Concluding remarks • Client files of energy companies have proven to be a very good source for making energy statistics! • Generally usable for all economic sectors with only consumtion of electricity and natural gas and no own energy production • Cheaper, more efficient, good quality, with little administrative burden compared to traditional surveys Statistics Netherlands
