Most TEA starts by developing a cost model. In general, the life cycle cost (LCC) of an energy storage system includes the total capital cost (TCC), the replacement cost, the fixed and variable O&M costs, as well as the end-of-life cost [5].To structure the total capital cost (TCC), most models decompose ESSs into three main components, namely, power conversion …
Energy Cost Index (ECI) Often viewed as overly simplistic, the ECI simply measures the total energy costs (such as electricity, steam, gas, water) of a company. It is expressed typically in dollars, as a percentage of total revenues, or as a delta to periods prior, typically annually. Certainly, it is comprised of demand and
