Energy expert makes case for solar-wind-storage only IRP with game changing ‘superpower’

An Integrated Resource Plan (IRP) comprising only solar, wind and storage (SWS) would deliver not only a load-shedding-free electricity supply industry but also create the platform for new industries to be built on near-zero-marginal-cost excess green electricity, a South African energy expert shows. Detailed modelling undertaken by Clyde Mallinson outlines that this alternative SWS IRP would involve the deployment, between 2021 and 2040, of 40 GW of new wind, 230 GW of solar photovoltaic (PV) and 35 GW/290 GWh of storage, comprising mainly of battery energy storage and mechanical gravitational potential energy storage.
