Ea Energy Analyses was a consultant for DEA (the Danish Energy Agency) in this modelling study. The objective was to study the potential impact of enhanced thermal power plant flexibility in the South African power system in the context of integration of increasing amounts of variable renewables (wind and solar). The focus was on the potential value of added flexibility for fossil power plants (mainly coal). This included analysis of new flexible fossil plants and retrofitting existing plants.
The modelling was carried out with the Balmorel model.
The project was part of the South African-Danish Energy Partnership Programme and was financed by DEA. From South Africa the power utility ESKOM participated in the project.
