Specific calculation method of energy storage intermediary income

How is energy storage capacity calculated?

The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.

How can energy storage technologies be analyzed for maximum profitability?

Based on the above arbitrage revenue and capacity costs, the potential selections of energy storage technologies can be analyzed in more detail for maximum profitability once breakeven costs are achieved via attainment of technology readiness and/or system cost reductions.

What is energy storage revenue based on price profile?

The revenue is considered as the income from the energy storage plant with various roundtrip efficiencies. Thus, an optimal methodology was developed to determine the largest revenue through the charging and discharging operations based on the price profile.

Can energy storage systems solve a demand-generation imbalance?

Energy storage systems can offer a solution for this demand-generation imbalance, while generating economic benefits through the arbitrage in terms of electricity prices difference. In the present study, a method to estimate the potential revenues of typical energy storage systems is developed.

How is system value per MW calculated?

The system value per MW for each benefit category is determined based on the C-rate of storage (Table 12). After accounting for the monetisable revenues and system value, as well as the costs of an electricity storage project, the project feasibility model should stack up the monetisable revenues and compare them to the costs.

What types of energy storage systems can esettm evaluate?

ESETTM currently contains five modules to evaluate different types of ESSs, including BESSs, pumped-storage hydropower, hydrogen energy storage (HES) systems, storage-enabled microgrids, and virtual batteries from building mass and thermostatically controlled loads. Distributed generators and PV are also available in some applications.
