What a battery earns in Spain, every day.
A free public dashboard with real electricity market data. We built it for our own studies and opened it up so anyone can check the numbers.
The starting point
It all starts with the gap between the cheap hour and the expensive one.
Storage Analytics calculates that spread every day using the price published by OMIE and converts it into euros per MW for batteries of different durations, standalone or alongside a solar plant.

From the arbitrage index to project IRR.
Each tab answers a specific question. Everything is recalculated with the plant type and battery you choose.

Numbers you can take to the bank.
Low, central and high scenarios with the metrics investors and lenders ask for, and a weekly forecast that shows how far off it is.
The figures in the screenshots change daily with the market. They are scenarios calculated from public data, not an offer or a revenue guarantee.
Open and free
Enter your plant and see what a battery would do.
Choose battery only, solar + battery or wind + battery, adjust the power ratings and the whole dashboard recalculates. No sign-up needed to browse.
