bvw1705 I remember seeing some of this in prospectus etc. so i went back and found a few snippets. this is from 2008 report- Completion of building the proto-type energy storage heat block, including the commissioning and completion of engineering design work associated with its construction, including its acceptance testing for inclusion of this technology within the King Island project.
page16 & page 12 have pictures of these 2 electrical items-
King Island - Resistive Frequency Control Unit This unit was designed and constructed by CBD subsidiary Remote Area Power Systems to enable significant reductions in diesel usage by enabling a greater proportion of wind power to be utilised
& CBD Energy - Large Scale Energy Storage Module Each module stores many MWh�s of electrical or thermal energy using the patented technology developed by CBD Energy. This is the first of the production modules planned for King Island.
There was also an article indicating an expansion of project.
