Energy storage power plant architecture price

The total investment cost consists of the EPC cost, EPC contracting fees and owner's costs. For conventional power plants, EPC costs include mechanical system costs, electric system costs, civil costs, and indirect costs.

Informing the viable application of electricity storage technologies, including batteries and pumped hydro storage, with the latest data and analysis on costs and performance. Energy storage technologies, store energy either as electricity or heat/cold, so it can be used at a later time.

The paper presents a cost comparison of thermal storage power plants (TSPP) with various conventional power plants. TSPP require less fuel and can better fulfill the demand of variable and intermittent residual loads through providing a much higher flexibility with their intrinsic heat storage system, also called Carnot Battery.

With the falling costs of solar PV and wind power technologies, the focus is increasingly moving to the next stage of the energy transition and an energy systems approach, where energy storage can help integrate higher shares of solar and wind power.

In the past decades, conventional power plants have been considered to be more cost effective than renewable power plants due to lower investment and fuel costs (e.g. comparing with biomass and biogas). Because of speculations and political disruptions, world market prices of fossil fuels have lately increased dramatically.

Column “Biomass Original” means the original biomass power plant that will be transformed, and component costs are taken from the EIA report . The LCOE is about 195 €/MWh. The second column”New TSPP equivalent to biomass plant” illustrates the costs in case of constructing a new TSPP equivalent to the original biomass plant.
