There is more information about this [url=http://www.energex.com.au/network/archived_distribution_network_assets.html]here[/url] (Look for Grovely and Grovely to Enoggera). It looks like a straightforward increase in capacity on a ‘business as usual’ basis.
These planning documents are interesting to read because they include such items as ‘Impact of doing nothing’ ‘risk mitigation’ in terms of risk to service delivery obligations and ‘greenhouse gas emissions’ in terms of minimising network losses and fulfilling reporting obligations.
These risk management considerations are standard engineering practice. Unfortunately they are only applied within the bounds of the system controlled (in this case) by Energex.
Who will undertake the same risk assessment of ‘Impact of doing nothing’ ‘risk mitigation’ and ‘greenhouse gas emissions’ for the total fossil fuel based energy system?
