Buying power for a cement plant months ahead means betting on numbers that will not be final until the month actually happens — how much the kiln and mills will run, how much captive solar and waste heat recovery will actually generate, and what the grid will charge at each hour of each day. Get the renewable share assumption wrong and a plant either buys more grid power than it needed or gets caught short during a peak demand window with no contracted supply. A forecast that connects the production plan, renewable supply assumptions and tariff structure into one view is what keeps procurement decisions grounded in the plant's actual operating reality instead of a rough average. Energy procurement teams who want to see their own forecast tested against the production plan can walk through a demand and renewable share forecast review with our team.
Buy Power Against What the Plant Will Actually Need
iFactory, an on-premise AI platform for cement energy management, connects the production plan, renewable supply assumptions and tariff scenarios into one demand forecast that procurement can act on.
Why Does a Forecast Built on Averages Keep Missing?
A forecast built on last year's average demand ignores the fact that a cement plant's load shifts with production plan, product mix and seasonal renewable output — none of which stay constant month to month. A forecast that treats demand as roughly flat will consistently miss both the peaks, where a demand charge penalty hits hardest, and the troughs, where contracted power goes unused. Ask our team how your current forecast accounts for production plan changes.
Three Tariff Elements That Change What "Cheap Power" Means
| Tariff element | What it means | Forecast implication |
|---|---|---|
| Time-of-use rate | Price varies by hour of day | Shifting flexible load to off-peak hours lowers cost |
| Demand charge | Billed on peak demand in a billing period | One bad peak can set the charge for the whole period |
| Renewable offtake terms | Contracted solar, wind or WHRS pricing and volume | Underused contracted renewable capacity is a sunk cost |

Forecast Accuracy Is a Metric, Not an Assumption
A forecast that is never checked against what actually happened stays unchallenged even when it is consistently wrong in the same direction. Comparing forecast demand against actual demand, period over period, is what reveals whether the renewable supply assumption is too optimistic or the production plan is systematically under-forecasting a particular product's energy intensity.
The Peak That a Flat Forecast Never Saw Coming
A plant's standard forecast assumed roughly even demand across the month. A production plan change — a high-output week to clear backlog ahead of a kiln maintenance shutdown — pushed actual peak demand well above the contracted level, triggering a demand charge the flat forecast had never flagged as a risk.

What Procurement Teams Ask About Demand and Renewable Forecasting
How far ahead should an energy procurement forecast look?
It depends on your contracting cycle, but most plants build forecasts covering at least the next quarter, with the nearest month refined against the most current production plan. Discuss a forecast horizon that fits your procurement cycle.
How is a production plan change reflected in the forecast?
When the plan changes — a high-output week, a planned shutdown, a product mix shift — the demand forecast should update accordingly rather than staying anchored to the original assumption. Ask support how plan changes flow into the forecast.
What happens when renewable generation underperforms the assumption?
The gap between assumed and actual renewable output should be tracked and fed back into future forecasts, so a pattern of underperformance — seasonal or otherwise — gets corrected for rather than repeated. Review your renewable assumption accuracy with our team.
Can this model multiple tariff scenarios at once?
Yes. Comparing forecast demand against several tariff structures side by side is how procurement teams evaluate contract options before committing to one. Walk through a tariff scenario comparison for your plant.
Who should own forecast accuracy tracking?
Energy procurement typically owns the metric, but it works best as a joint review with production planning, since most forecast misses trace back to a production plan change the forecast had not yet absorbed. Ask about a joint review cadence.
