Nuclear, Hydro, Solar and Renewables Data

Data Management
Data collection methods.
 Data provided to the Department via Email and fax and mostly on excel
format
 Formal agreements with data providers entered into.
 Data provided to the Department on pre-defined periodic basis.
 Currently, there is scientific/ probability based data collection as all identified
data providers are requested to provide data to the Minister.
 Regulations on the Provision of Energy Data (Driven from the National
Energy Act of 1998)
Data Management
Data preparation
 Data is received and captured in the commodity flow spreadsheet in native
units as well as in the Energy database.
 The commodity flow spreadsheet is imported into the Energy Database and in
the process, the native units are converted into a single unit (TJ). This
becomes the Basic file
 The aggregated and the disaggregated files are also created during the
importation process.
Data Management
Data Quality Control
Computer System based...
 Comparisons of current figures with historical data to identify obvious outliers.
 Built-in conversion functionality in the database.
 Built-in functionality to detect when a wrong is attached to a figure.
 Built-in functionality to detect unrealistic statistical difference.
 Final consumption of Gas by Sector (Gas Refining companies, LPG
Association and other sector organisation)
Non Computer based...
 Internal Review by relevant sections within the Department.
 Review by External stakeholders, including data providers and industry
experts.
 The Minister to be requested to approve the revision of some of our data by the
IEA.
 An Energy Statistics Review Team has been established to review the Energy
Balances from time tom time.
Data Management
Publication
 The Basic, aggregated and disaggregated balances are published in the
website after approval by the Director-General
 The Digest of South African Energy Statistics is produced out of these file and
published on approval by the Minister of Energy.
 Local and Global reporting obligations ( UNSD, StatsSA and other organs of
