Battery Investment Decision Tool for Utility Scale Renewable Projects

DeBatT is an investment decision tool for batteries deployed in utility-scale renewable projects such as hybrid wind-solar PV parks. The tool estimates the lifetime of batteries with a deviation of up to 2 months for 10-year lifespan and the levelized cost of storage with at least 30% higher accuracy than traditional methods. By using this tool, system integrators can assess their investments in new renewable-based projects, where batteries are critical for achieving grid and market integration. Batteries are the most expensive components since storing 1 MWh renewable energy may be 6000 times more costly than producing it. DeBatT will enable a faster green transition by accelerating deployment of battery-based utility-scale renewable projects.
