SEA update & procedure for downloading solar datasets

Brief update on the solar PV SEA process
Subsequent to the first project steering committee (PSC) or expert reference group (ERG) meeting in March 2013, the CSIR has refined its methodology and results based on all comments and recommendation received. Refinements include:
·         additional datasets; and
·         determination of development potential through normalisation based on pull factors e.g. high social need area, industrial hubs/ports, network losses and substations.
Delays have predominantly resulted from the submission and verification of data.
The DEA is currently reviewing the DEA EIA application mapping and report which will be released as soon as it is approved.
The second PSC /ERG meeting is planned for 31 July 2013 where the new results will be presented.
