6 FAQs about [Calculation of residual value of energy storage system]

How is electricity storage value assessed?

Values are assessed by comparing the cost of operating the power system with and without electricity storage. The framework also describes a method to identify electricity storage projects in which the value of integrating electricity storage exceeds the cost to the power system.

How do you calculate system value per MW?

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.

How can esvf help regulators assess the value of electricity storage?

The ESVF presented in this report is intended to support regulators and other stakeholders in the use of modelling tools to assess the system value of electricity storage in a power system and assess the monetisable revenues of storage projects under an existing regulatory framework.

What are electricity storage systems?

Electricity storage systems are one flexibility option among others such as flexible conventional energy generation, grid expansion, demand-side-management and electricity import/export. At high shares of renewable energy in the electricity sector, application of storage technologies becomes more and more important , , .

What is the relationship between PV and storage?

In the first part the general relations for PV and storage were derived and various parameter variations were discussed for both systems separately. For storage it is assumed that solely the cumulated stored energy determines the LCOE of the storage system. It turned out that C rate is the most important parameter for the LCOE of storage.

What is the difference between total lifetime cost and energy output?

The total lifetime cost is the sum of the cost of PV energy generation and the cost of storage. The energy output of the PP is the sum of directly used energy from PV and the amount that is taken from PV to the storage system and then released to the output of the PP.
