Background Situation energy statistics in the Netherlands in 2005 Positive: energy production sector and Background Situation 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 2

Background Situation energy statistics in the Netherlands in 2005 Negative: Other sectors (households, service Background Situation 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 questionnaires But: • increasing demand Statistics Netherlands 3

Promising alternative ask energy companies for their files with individual client information The idea Promising alternative ask energy companies for their files with individual client information The idea is simple: v 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 v Collecting this individual client information is much more efficient and less costly than asking many individual consumers Statistics Netherlands 4

Advantages v Only a limited number of respondents have to be bothered (general policy Advantages v Only a limited number of respondents have to be bothered (general policy in the Netherlands to minimize the response burden) v Less costly and more efficient v 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) v Data on energy consumption can be published for each economic activity (NACE-code) and households annually Statistics Netherlands 5

Steps forward (1) Legal obligation v Energy companies will not cooperate on a voluntary Steps forward (1) Legal obligation v Energy companies will not cooperate on a voluntary basis v Legal obligation is necessary v Realised in 2004 as modification of the Dutch statistical law Statistics Netherlands 6

Steps forward (2) which companies: energy suppliers or network operators? v Energy suppliers: - Steps forward (2) which companies: energy suppliers or network operators? v Energy suppliers: - more information (quantities, prices, costs, taxes) - more and varying number of companies - varying number of clients/connections per company (switching allowed) v 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 7

Steps forward (3) Identify type of client: house hold or business? and type of Steps forward (3) Identify type of client: house hold or business? and type of business (NACE code)? v Records contain address data v 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) v Amount of energy Statistics Netherlands 8

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

Concluding remarks • Client files of energy companies have proven to be a very 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 26
