General Principles

The database is updated each year following the annual survey of renewable energy schemes. This serves three purposes:

• To collect information for the year from projects already held on the database;
• To improve the quality of information held on these projects where necessary;
• To collect information from projects not already on the database - either new for the year, or not already known to RESTATS.

It is an important source of new data. Due to the confidential nature of the data only aggregated results are made available.

The Approach

The information contained in the database is collected by a number of methods, including linking up with other surveys

• Large projects: annual survey through questionnaires sent to project managers. Large numbers of small projects: estimates based on information collected from a sub-sample of the projects

  • Renewable Energy Projects Survey (REPS) Questionnaire
  • Waste-to-Energy Questionnaire; for small-scale specialised waste combustion projects
• Mail shot - December; follow-up - January
• Telephone follow up of non-respondents
• Estimates, where data are not available
• Review quality and completeness; plan - ‘gap analysis ’surveys
• On-line Survey Form now on offer

Continuous Improvement

• RESTATS has a programme of continuous improvement to data quality
• The survey highlights areas where better data are needed (‘Gap Analysis Survey’)
