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.
The value of electricity storage is assessed by comparing the cost of operating the power system with and without electricity storage. This framework also describes a method to identify projects where the value of integrating electricity storage exceeds the cost to the power system.
The innovative market product presented in the previous section can incentivise the deployment of energy storage systems. This is because it will provide an additional revenue stream, making these projects more economically feasible.
At low levels of variable renewable energy (VRE), electricity storage providing energy arbitrage could be contributing to increasing the capacity factor of cheap coal power plants and their energy share in the mix, as their lack of flexibility is compensated by storage flexibility.
When connected at the distribution level, electricity storage can provide power quality and reliability services at the local substation, defer distribution capacity investment, and support integration of distributed renewable energy.
Electricity storage developers employ a variety of market-specific business models to make their projects viable. One example is that of aggregators for distributed storage.
