How to calculate financial feasibility of gravity energy storage project?
Life cycle cost analysis To calculate the financial feasibility of gravity energy storage project, an engineering economic analysis, known as life cycle cost analysis (LCCA) is used. It considers all revenues, costs, and savings incurred during the service life of the systems. The LCC indicators include NPV, payback period, and IRR.
Does gravity energy storage have a return on investment (ROI)?
