READ MOREIt can be seen below that the cost-optimal means of meeting the electricity demands as the renewable energy penetration is increased, is by first adding wind capacity. This is due to the fact that wind energy was the cheapest production method on all the islands except for Sumba. Increasing wind capacity was effective up to a critical point
READ MOREAt present, renewables are cheaper than gas. A minimum cost of 69.05 £/MWh is found at a wind penetration of 57%. After this point, the TCoE starts to increase due to the increasing capex of the energy storage, which increases exponentially as the overall penetration of renewables approaches 100%.

India''s power generation potential
READ MORETo achieve the decarbonisation of the electricity sector, a significant amount of renewable energy sources (RES) generation capacity is required to replace the phased-out fossil base load capacities. This process involves electrifying other energy sectors (e.g. transport), which will further increase the electricity demand to be covered by RES.
