There are four main steps involved in assessing the capacity value of energy storage, namely: Calculating the loss of load probability (LOLP). Obtaining the optimal decision policy for the storage operation for each hour using stochastic dynamic programming. Computing the probability distribution of the energy stored.
The cost mainly depends on the energy storage technologies and it is difficult to evaluate as it is influenced by several factors such as the storage type, the application requirements, the size and so on. However, the capital cost of the energy storage can be calculated in the ways such as cost per kW, per kWh and per kWh per cycle.
The electrical energy storage system is designed to compensate for load power shedding and surges inadmissible for gas engine generators. Table 1 shows the input data necessary for LCOS calculation. The base prices shown in Table 1 were used to calculate the value of the levelised cost of energy storage.
Nevertheless, as of today, there is no generally accepted economic indicator which would allow us to compare different energy storage systems, unlike in the planning of construction of power plants, for example, where the indicator “Levelised Cost of Electricity (LCOE)” has been accepted.
At the design stage, the amount of electricity delivered over its lifetime can be calculated based on the service life of the storage unit, determined by the number of complete charge-discharge cycles, or based on the estimated lifetime of the ESS considering its operation mode, for example, operating as a backup power supply. 3. LCOS calculation
The following energy storescan be calculatedfrom other quantities: Thermal Energy= (Mass) x (Specific Heat Capacity) x (Change in Temperature) Elastic Potential Energy= 0.5 x (Spring Constant) x (Extension)2 Kinetic Energy= 0.5 x (Mass) x (Speed)2 Gravitational Potential Energy= (Mass) x (gravitational field strength) x (change in height)

Get PriceIn general, the levelised cost of storage shows the intrinsic value of a kWh of energy delivered by an ESS, for which it should be sold to achieve a zero net present value (NPV). The LCOS is determined as the sum of all investments over the lifetime of an ESS divided by the cumulative energy generated as a result of these investments.
