Analyze PV, Wind & BESS hybrids in seconds
An online tool to explore renewable generation and battery energy storage (BESS) hybridization. It can also test PV+Wind hybrids and standalone BESS scenarios.
How it works
Upload one full year of hourly data (8,760 hours of production and electricity prices) using our Excel template.
Electricity prices options (Spain): By default, we have a built-in reference dataset based on the Spanish wholesale market (2025) which serves as a consistent baseline. The best option is to provide realistic prices in the template.
