"See the part most quotes leave out. The Smart Power Plan is a full simulation of your site's energy, hour by hour and tariff window by tariff window, that shows exactly what to build and what it will actually save, before you spend a cent on equipment.
Most proposals lead with one number — total savings, total offset — because it's the easiest thing to sell. What they leave out is the breakdown that proves it: the TOU-specific offset assumptions, the transformer capacity check, the demand-charge modelling.
If you're the GM who got the CAPEX approved, or the ops manager who has to stand in front of the board, the Smart Power Plan is what makes your recommendation defensible.
You walk into that meeting with the working, not just the conclusion.
This is what the Smart Power Plan looks like in practice. Three outputs from a real SolarPlus simulation — the same methodology we use for every engagement.
The foundry's load profile showed a consistent demand spike in the morning peak window — the most expensive electricity on Megaflex tariffs. The model identifies exactly how much battery capacity is needed to shave that peak below the demand charge threshold, and what that saves per month in rand terms.
This is the output most proposals skip. It is also the one that drives the majority of the savings.
Batteries charged at the off-peak rate (R1.82/kWh) discharge during the peak window (Up to R7.72/kWh). The model shows the seasonal arbitrage margin per cycle, the number of cycles per month, and the cumulative rand value — hour by hour across a full year, not as a single blended estimate.
The foundry's arbitrage contribution alone covered a significant portion of the system's annual repayment.
The final output is a month-by-month savings projection for year 1, broken down by demand charge reduction, peak kWh offset and off-peak arbitrage. For this foundry, the combined effect was a 42% reduction on a R800k/month bill — with the payback period stress-tested at 8% annual tariff escalation.
This is the document that goes to the CFO. It has the working, not just the conclusion.
A full walkthrough of the SolarPlus simulation — how the model works, what each output means, and why the methodology produces numbers a finance committee can actually trust.
