Spot Optimizer

Pay less for the electricity your process already needs.

Spot Optimizer combines your equipment’s power profile with published electricity prices to show what each run would cost at different start times. Even a small change in start time can lower production costs. A seven-day AI price forecast helps planners choose when to run production and when to stop for maintenance.

Use Spot Optimizer independently on existing equipment.

Electricity cost by start time

Cycle cost in SEK

Day-ahead prices
Electricity cost for the same cycle at different start times. The operator demo has a lower-cost window early on Tuesday.
Each point is the cost of the same complete run at a different start time. Compare the starts your shift can use.

Electricity cost over the week

Cycle cost in SEK

Published pricesForecast prices
Published and forecast electricity costs for the cycle across the week. Lower points indicate lower-cost start times.
Use lower-cost windows for flexible runs and consider forecast peaks for planned stops.

Spot Optimizer

How it works

An electric arc furnace can start a heat while power is cheap and reach peak demand after the price rises. Spot Optimizer applies the electricity price in each interval to the energy used in that part of the cycle. The operator sees the cost of the whole heat at each possible start.

Choose a start time on shift

Operators compare starts five minutes apart and see the cost difference across the next 30 minutes. The dashboard shows when the next lower-cost start occurs and what the run would cost. It uses published day-ahead prices for today and, when available, tomorrow.

Six possible starts

14:15 2,079.9

Of the six starts shown in this demo, 14:40 has the lowest calculated electricity cost.
Plan the week ahead

The weekly view combines published prices with machine-learning forecasts to estimate cycle costs over the next seven days. A separate break-planning view helps planners move required downtime into the most expensive periods their schedule allows.

Cost per run (SEK)

In the weekly demo, the estimated cost per run falls after the transition from published to forecast prices and rises again later in the week.
The vertical dashed line marks the change from published prices to forecasts. Planners can use the peaks to time a maintenance stop.
Review completed runs

Operators log each start. To review a process, select the period, production schedule and number of expected runs. The savings view compares costs at the logged starts with the period average and shows what share of expected runs the team recorded.

How savings are calculated

Savings view
Period average
Average cost of a cycle across all possible start times in the period.
Logged average
Average cost of the same cycle at the starts your operators recorded.
Reporting rateLogged runs ÷ expected runs
When the logged average is lower, the difference shows the estimated electricity saving per run.

Spot Optimizer

What is timing worth at your plant?

Start with a run your team repeats or a maintenance stop you can move. The business case depends on your power profile, your scheduling flexibility and how your electricity contract reflects spot prices.

Which processes are a good fit?

Look for an electricity-intensive process with a short or medium-length cycle and some choice over when to start. Examples include steel, aluminium, mining, pulp and paper, and chemicals. A pronounced power peak within a cycle makes the timing of that peak especially important.

How much could a change in timing save?
Timing individual runs
2–9%Estimated savings potential when starts can move by 10–60 minutes.
Planning production and stops
4–17%Estimated savings potential with forecast-based scheduling. The number of hours the plant needs to stop affects the opportunity.

Both estimates depend on the electricity price area and the process power profile. We assess each opportunity against the schedule your team can use.

What does Ferroman assess?

We use your power profile, local electricity prices and scheduling limits to calculate the cost of a run at each feasible start. Your team can see what a change is worth per run and how often it fits production.

Ferroman can also help your operators use these comparisons on shift.

How is Spot Optimizer priced?

Pricing is based on your plant’s power consumption. Ask Ferroman for a Spot Optimizer quote.

Ferroman Furnace Energy Intelligence

Look beyond the start time.

If your furnace burns gas, Ferroman Heatbox can replace part of that gas with electric preheating. The price of power during a run then matters to your heating costs, too.

Ferroman can assess heating and scheduling together. You can also use Spot Optimizer on its own.
