Prepaid meters are actually very simple to install and manage.
Implementation of prepaid metering would enable an owner/investor to manage the utility/electricity on an individual user basis and allow them to charge for the utility on a pay as you go basis.
From a developer's point of view, prepaid meters would contribute towards meeting the criteria of the Green Star Multi- Unit Residential v1 (Energy Criteria), thereby enabling them to market a utility efficient green investment hopefully at a premium price.
Furthermore prepaid meters can be used by the management rights/owner/investor/property manager of the building as a tool for monitoring and charging for excess electricity/water/gas usage thereby causing behavioural change and saving electricity.
At the same time prepaidmeters allow excess usage to be charged thereby giving a return to the owner/investor/manager.Prepaid meters also help with utility cash flow as it enables the owner to be paid upfront for any usage.
