Financial and economic modeling of large-scale gravity energy
This work models and assesses the financial performance of a novel energy storage system known as gravity energy storage. It also compares its performance with alternative
The sales generated by the project are referred to as revenue. The revenues for an energy storage system performing energy arbitrage service are the product of the agreed energy price with the net discharged power.
A Growing Need for Energy Storage The increasing generation of renewables on the Japanese grid has led to various support policies and CAPEX subsidy schemes to support the deployment of grid-scale Battery Energy Storage (BESS).
The project investment in all the studied energy storage systems is demonstrated viable to both project sponsors and lenders since the IRRs of the project for all systems in their last year of operation are larger than the projected WACC and the IRR of equity in their maturity year are better than the return on equity. 5. Financial analysis
Financial and economic modeling are undertaken based on the data and assumptions presented in Table 1. Table 1. Project stakeholder interests in KPIs. To determine the economic feasibility of the energy storage project, the model outputs two types of KPIs: economic and financial KPIs.
