Capacity credit is based on AEMO analysis of NSW rooftop solar generation.
Its annual capacity factor is substantially higher than the average for South Australia.
High Temperature Gas-cooled Reactor
The Shidaowan HTR-PM demonstration plant – for which the HTR-10 shown above is the prototype – is being built by the state-owned China Huaneng Group. Cost is derived from that reported for the twin-unit plant – in practice, two reactors will power one turbogenerator of about 210 megawatts and can be ramped for load following operation. The design precludes all concerns of loss-of-coolant accident scenarios.
More details on the inherent safety and security of this nuclear reactor design are here. Technical paper here. Availability factor used for capacity factor. China intends to export the design to Saudi Arabia.
(As the commercial operation of a nuclear plant assures full output at practically every period of high demand, capacity credit does not apply.)
