Renewable energy, demand, and the grid

Question 1

What are two reasons for the electricity sector to need to become more flexible?

Answer 1

• The need to avoid overloading the grid
• The variability of renewable energy

Question 2

Why is there a growing threat of overloading the grid linked to decarbonisation?

Answer 2

• Renewable energy that can be generated by homes and businesses means there must be a two-way flow of electricity when it was only designed for one-way flow.
• Decarbonisation of heat and transport will largely take place through electrification, emphasising peak time loads

Question 3

Why is the variability of renewable energy a reason for the need for flexibility in the grid?

Answer 3

• generation of renewable energy will peak at certain times which may not align with peak demand times.
