This report provides a technical overview of RayGen’s thermal hydro system, covering elements such as system layout, efficiency and costs.
This report is the second part of ‘The Story of RayGen’. Readers should acquaint themselves with ‘Part I – Commercial Assessment Report’ for context on RayGen and the RayGen system.
RayGen’s Solar Power Plant is a grid-scale solar-plus-storage technology. It competes with other electricity generation and storage technologies that supply power to electricity networks and/or large energy users. RayGen’s technology must be cost-competitive with technologies that offer similar capabilities – including generation profile, reliability and ancillary services – to compete effectively over time.
RayGen’s competitors include fossil fuel generation technologies (e.g. gas-fired generation), dispatchable renewable generation technologies (e.g. hydroelectricity, concentrated solar thermal), intermittent renewable generation plus storage technologies (e.g. solar PV panels plus batteries, solar PV panels plus pumped hydro) and stand-alone storage, both established (e.g. lithium-ion batteries, pumped hydro) and emerging (e.g. adiabatic compressed air energy storage, electro-thermal energy storage, flow batteries, mechanical storage, virtual power plants).
