Title: National Grid Hydro pumped storage Pumped Storage - Hydro 2011 Content: Items that this cost includes Items that this cost excludes Detail on the conditions under which this cost is valid * Assumes O&M costs of £1/MWh based on 2011 gross generation and pumping of 2040GWH. * Capital costs of £1bn per 2GW. The figures are based on an assumption of £1/MWh on 2,040,000MWh gross (pump and generation) then this would equate to £2,040,000 of O&M (operate and maintain). Dividing this through by 1,728MW (1,728,000kW), on (6 x 288MW units at Dino), this would give £1.18/kW.
