Choose the Sizing Your Operation Needs
Energy Portfolio Simulator (EPS) compares sizing options of PV, battery storage, and EV charging against the real data of your site and shows which one pays back fastest and returns the most over its lifetime.
What is Energy Portfolio Simulator?
EPS compares sizing options of PV, battery storage, and EV charging against the real data of a specific site – its 15-minute consumption profile, local irradiance, tariffs, reserved capacity, and market prices.
It simulates how each option would be operated day to day: smart battery management against consumption, generation, and market prices, EV charging against PV and battery, reduction of the quarter-hour maximum, and limits on export at negative prices.
The comparison reflects real operation, not a static energy balance.
Already Built It?
EPS sizes the PV and battery before the investment. WattNext plans their dispatch once they are in place.
Decide on the Numbers You Already Use
Every sizing option is evaluated with payback period, NPV, ROI, TCO, and LCOE, including the effect of subsidies. Results come within hours to days, data preparation included.
Payback and NPV
How long the investment takes to return, and what it is worth in today’s money.
ROI and TCO
What the return looks like against the full cost of ownership over the asset’s life.
LCOE
The average cost of every kilowatt-hour the installation produces across its lifetime.
