Legal Framework
 Legal framework for energy data collection was
enshrined in the Energy Commission Act (Act 541)
which was passed by the Parliament of Ghana in 1997
 Act mandates the Commission to collect energy data to;

Administrative Data Sources - Benefits
 Minimizes cost
o
Reducing cost of undertaking surveys
 Reduces data collection errors
o
Data collected covers all entities engaged in that activity
 Source of information for planning surveys
o Useful source of information to be used as sampling
frames for undertaking surveys
 More efficient

7/23/2016
Uses data already in existence thus avoiding duplication of work
19
Challenges
 Legal barriers and obligations
o Public institutions/regulators hence not obliged to provide
data
 Timeliness
o Data not provided on a timely basis to meet publication
deadlines
 Increased workload
o More work added to the officer in charge
 Data quality
o data collected to serve a particular purpose not necessarily for
energy statistics
o Regulatory requirement; manipulation of data
7/23/2016
20
Conclusion
 Administrative data


will continue to be an important source of information for
energy statisticians;
Reduces respondents burden, cost and increased output
 Continuous dialogue and cooperation with
institutions/officers, and always ensuring a win - win
situation
