This Gantt chart presents estimated times and costings to construct a power plant using assumptions which will almost certainly be
modified following the findings of the initial ~2km test hole. Eighteen months have been estimated to drill and log this hole, and
included in this time-frame is a scoping study designed to tighten both costs and potential incomes.
Following completion of the test hole, informed planning for the initial plant capacity can take place. The 26MW plant used below is an
arbitrary size, originally chosen for the high-level financial modelling, since a sub-30MW plant may have less stringent requirements to
join the NEM. A total of four years has been allowed to complete the drilling, install the turbines, generators, etc, and connect to the
grid.

As previously mentioned, the scoping study may include costings for a demonstration plant. A rough estimate indicates a ~0.5MW
(gross) plant might cost $20M for a low temperature plant using two slimline holes, one being the initial test hole, and would take
perhaps 3 years to complete. Some direct use applications would be able to commence as soon as two holes; i.e., one production hole
and one reinjection hole, had been completed and cased.View entire presentation
