Examples of operation and maintenance costs are fuel expenses, cost of plant and system maintenance, cost of power system operation, cost of storage, and plant decommissioning. The oil and gas fired power plants e.g. coal, gas, biomass have significant costs in form of fuel cost ( Raikar and Adamson, 2020 ).
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
