READ MORERenewable energy technologies are expected to take the leading role in the forthcoming energy generation portfolio in order to achieve sustainable energy generation. The major constraints for increasing penetration of renewable energy sources is their availability and intermittency, which can be addressed through energy storage when
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%.
