General comments:

The Project uses concentrated solar power focused into a graphite Solar Storage Receiver (SSR), set out in a multi tower solar array. The Project included building a solar thermal power plant which consists of eight SSR’s each mounted on its own tower, with dedicated dual axis tracking reflective heliostat fields of approximately 760m2.

Each of the SSR’s are effectively an on demand steam generator, which is connected by a steam manifold that delivers the steam to the balance of plant and a 3MWe steam turbine generator, which is in turn connected to the Australian National Electricity Market.

This SSR is a graphite block which act as receiver, boiler and storage system.
