## In short

Pick the roofs to cover, add open access solar and wind, add battery storage, and run the year. The campus starts on grid electricity at ₹6.70/kWh and ends, in the illustrative case, at ₹3.89/kWh with the portfolio drawn on the site plan and the supply stack shown hour by hour. It is a demonstration of how the pieces fit for a very large round-the-clock load, not a quotation.
## Facts

- The illustrative campus is a 5 GW/yr TOPCon solar-cell gigafactory with a round-the-clock load.
- The illustrative cost of electricity moves from ₹6.70/kWh on grid to ₹3.89/kWh on the full portfolio.

## Assumptions and limits

- All figures are illustrative; tariffs, capacity factors and open access charges are state- and year-specific.

## Questions and answers

**Is this a real project?**  
No. It is an illustrative demonstration carried over from a standalone jouleWise demo. The numbers are internally consistent for the campus shown, not a client result.

**Can I run it for my plant?**  
Use REplanner to size a portfolio against your own consumption, or ask for a four-week baseline, which builds the case on your metered load.
