Changing the entire energy system isn’t easy – here’s why.
Changing the entire energy system isn’t easy – here’s why.
To complement renewables, we will need power plants that can change how much energy they produce relatively quickly. To pay for such reserve generating capacity, the power market will need to be redesigned.
A power system designed around renewable energy must both be flexible and allow for power storage. Rather than relying on “baseload” power like coal and nuclear, Germany is trying to switch to a supply-based model.
Dispatchable power plants are those that can change how much power they provide to the energy grid quickly. They can be switched on and off, or ramped up and down to meet power demand.
Backup power is not a clearly defined term. In general, it indicates that certain power plants need to be maintained on standby in case other generators fail to produce power.
Baseload is the minimum amount of power that a country needs around the clock.
