Can solar power replace coal?

If solar power was used to replace a significant amount of coal fed to a power plant (operating in ‘coal saver’ mode), the overall amount could actually decrease, although this would not be the case with plants operating in ‘solar boost’ configuration.

Can solar power be combined with coal-fired power plants?

Two possible options are explored here: combining solar energy with coal-fired power generation, and cofiring natural gas in coal-fired plants. Both techniques show potential. Depending on the individual circumstances, both can increase the flexibility of a power plant whilst reducing its emissions. In some cases, plant costs could also be reduced.
