Building an S&OP Process for Power Generation Companies

By James C on October 10, 2026

power-plant-s-and-op-process

An S&OP process for a power generation company brings fuel, maintenance and dispatch planning into one monthly decision cycle. Sales and operations planning is a manufacturing method, but the problem it solves is familiar to every genco: three teams plan separately, and the conflicts only appear when it is too late to avoid them. An outage lands in a peak month, or coal stock runs low just as demand rises. This guide shows how to adapt the method to generation, step by step. To see a shared planning view for your fleet, book a short walkthrough.

Building an S&OP Process for Power Generation Companies: One Plan for Fuel, Maintenance and Dispatch

A monthly cycle that puts fuel, outage and dispatch plans on one page, finds the conflicts early and gives leaders a clear decision to make.

Key takeaways
1
S&OP is a meeting rhythm, not a system

Five steps each month, ending with decisions by senior leaders.

2
Gencos already plan; they rarely plan together

Fuel, maintenance and dispatch usually sit in separate teams and files.

3
The value is in the conflicts found early

An outage against a demand peak, or a fuel shortfall before a high-load month.

4
One set of numbers

Everyone works from the same forecast, the same outage dates and the same stock position.

01The basics

What Is S&OP, and Does It Apply to Power Generation?

Sales and operations planning is a monthly process that balances demand and supply and ties both to the financial plan.

In plain words
S&OP

A monthly, cross-functional planning cycle. Each function refreshes its plan, the gaps are worked through together, and senior leaders approve one agreed plan.

S&OP is a manufacturing term. We found no published case of a generating company running a formal S&OP under that name. Gencos usually call the same idea integrated planning. This guide applies S&OP principles to that work.
  • Demand side. For a genco, this is the dispatch forecast: how much the grid or customers will take.
  • Supply side. Unit availability, which depends on maintenance, and fuel, which depends on supply and logistics.
  • Finance. Revenue, fuel cost and penalties that follow from the combined plan.

The method fits because the structure is the same: several plans that depend on each other and must agree. We can map it to your planning calendar on a call.

02The problem

Planning in Silos: Fuel, Maintenance, Dispatch

Each team makes a sensible plan on its own. The trouble starts where the plans meet.

Fuel
Buys and moves fuel

Works from a generation forecast that may be weeks old.

Maintenance
Plans outages

Fixes dates around contractors and parts, not always around demand.

Dispatch
Commits generation

Assumes units and fuel will be there.

Finance
Budgets the year

Sees the effect only when results arrive.

ConflictHow it happensWhat it costs
Outage in a peak monthOutage dates set before the demand forecast was revisedLost generation when it is worth most
Fuel short before high loadFuel plan based on last quarter’s dispatch viewUnits backed down or stock run below norm
Too much fuel during an outageDeliveries not adjusted for a unit being offlineStockyard congestion and carrying cost
Two units out togetherPlants plan separatelyFleet availability falls below commitment

None of these needs new technology to prevent. They need the three plans on one page, reviewed together. See what that looks like in a demo.

03Why it matters

Why Coordination Matters More Now

Availability rules, tight scheduling and thin fuel stocks all reward gencos whose plans line up.

When stocks are this thin, a fuel plan that lags the dispatch plan by even a few weeks can leave a unit short. The same is true of an outage that overruns into a high-demand period.

A monthly cycle keeps the three plans in step. Our specialists can show where yours diverge today.

04The cycle

The Five-Step Monthly Cycle, Adapted for a Genco

The standard S&OP cycle has five steps. Each maps cleanly to generation planning.

Step 1
Data

Close last month: generation, availability, fuel receipts, stock.

Step 2
Demand

Refresh the dispatch forecast by unit and month.

Step 3
Supply

Refresh outage and fuel plans against it.

Step 4
Pre-meeting

Find the conflicts; prepare options.

Step 5
Executive

Decide; approve one plan.

StepWho leadsMain output
Data reviewPerformance teamPlan against actual for the month
Demand reviewCommercial and schedulingDispatch forecast for 18 months
Supply reviewOutage and fuel planningOutage calendar and fuel plan
Pre-meetingPlanning headList of gaps with costed options
Executive meetingSenior leadershipApproved plan and decisions

The discipline is the calendar. Each step happens in the same week every month, so the executive meeting always has fresh numbers.

A first cycle can run on existing data. We set up the calendar and views in every rollout.

05Horizons

How S&OP Fits With Other Planning Horizons

S&OP covers the middle ground between daily scheduling and long-range resource planning.

ProcessHorizonDecides
Day-ahead schedulingNext day, in 15-minute blocksUnit commitment and declared capability
S&OP or integrated planningRolling 18 months, reviewed monthlyOutage timing, fuel plan, generation targets
Annual outage and load planOne yearRegional outage schedule; in India, the LGBR prepared with the Regional Power Committees
Integrated business planning24 to 36 monthsAdds financial and strategic reviews
Integrated resource plan10 to 20 yearsNew capacity and retirements

Integrated business planning is the later, wider form developed by Oliver Wight in 2005. It adds strategy and finance reviews and looks further ahead.

Most gencos already have the top and bottom rows. The monthly middle layer is the usual gap. Ask our team how it connects to both.

06One view

What Goes on the Shared View

The whole process rests on one page that every function recognises as true.

Dispatch forecast
Expected generation by unit and month, with the range of uncertainty.
Unit availability
Planned outages, expected forced outage allowance and deratings.
Fuel position
Opening stock, planned receipts, expected burn and closing stock in days.
Gaps
Months where availability or fuel falls short of the dispatch forecast.
Financial effect
Revenue, fuel cost and any availability shortfall.
Decisions needed
A short list, each with options and an owner.
Example: closing coal stock by month, in days of burn
October16 days

November9 days

December12 days

January18 days

Illustrative. A dip like November’s is the kind of gap the pre-meeting should resolve.

Days of stock, outage dates and forecast load on one chart make conflicts obvious. See yours in a session.

07Scenarios

Testing a Decision Before the Meeting

The pre-meeting should bring options with numbers, not problems.

Example: moving a unit overhaul by two weeks
Original start4 November, 25 days
Forecast peak demandWeek of 4 November
Lowest planned coal receiptsSame week
OptionStart on 18 November
Effect on peak-week generationUnit available for the peak
Effect on fuelStock dip avoided; receipts recover first
Decision for leadershipApprove the two-week move

Illustrative. Real options should carry revenue, fuel and contractor costs.

  • Bring two or three options. Including doing nothing.
  • Show the cost of each. In the same units, so they can be compared.
  • Name the constraint. Contractor dates, grid approval or parts.

Scenario tools make this quick. Our engineers can set up the common cases.

08Roles

Who Does What

Clear ownership keeps the cycle running when people are busy.

RoleResponsibility
Process ownerRuns the calendar and the pre-meeting; usually the planning head
Commercial leadOwns the dispatch forecast
Outage planning leadOwns the outage calendar
Fuel leadOwns the fuel and logistics plan
Finance leadTranslates the plan into revenue and cost
Plant headsConfirm unit capability and risks
Executive sponsorChairs the decision meeting and settles trade-offs

The executive sponsor matters most. Without someone able to settle a trade-off between functions, the meeting becomes a status report.

A one-page charter with these names is a good first deliverable. Discuss it with our advisors.

09Measures

How to Tell if It Is Working

A few plan-against-actual measures show whether the cycle is improving decisions.

96%
Generation against plan
88%
Fuel receipts against plan
92%
Outage days against plan

Illustrative values. The lowest ring is the first topic for next month’s review.

  • Forecast accuracy. Dispatch forecast against actual generation.
  • Outage adherence. Start date and duration against plan.
  • Fuel plan adherence. Receipts and stock days against plan.
  • Availability. Declared availability against target.
  • Late changes. How many plan changes were made inside the month.

Published S&OP benefit figures come from manufacturing and should not be read across to power. Measure your own baseline and track it.

Fewer late changes is usually the first visible sign. We set up the measures in a working session.

10Comparison

Siloed Planning vs an Integrated Cycle

The difference shows in how surprises are handled.

Siloed planning
  • Three plans in three files
  • Conflicts found when they happen
  • Each team defends its own plan
  • Leaders hear about problems late
  • Finance sees results after the month
Integrated cycle
  • One shared view
  • Conflicts found months ahead
  • Options prepared together
  • Leaders decide on trade-offs
  • Finance sees the effect of each option

The change is in behaviour more than tools: a fixed calendar and a habit of bringing options. A pilot on one plant shows it in practice.

11Pitfalls

Common Pitfalls

Most failed attempts share a few causes.

  • No executive time. If leaders skip the meeting, decisions drift back to the silos.
  • Too much detail. The review should look at months and units, not hours and valves.
  • Different numbers. If teams bring their own figures, the meeting argues about data.
  • No options. Presenting a gap without a proposal wastes the meeting.
  • Looking backward. Spend most of the time on the next three to eighteen months.
  • Treating it as a report. The output is a decision, not a slide pack.

An Outage, a Peak and a Fuel Dip in the Same Week

This is how a planning head might prepare for the monthly review.

Planning head and iFactory AI
Planning head
Do the three plans agree for November?
iFactory AI
Two of the three do. The Unit 3 overhaul starts on the 4th, the same week the dispatch forecast peaks.
Planning head
And fuel?
iFactory AI
Coal receipts are planned to be lowest that week. Stock would fall to about nine days against a norm of seventeen.
Planning head
What are the options?
iFactory AI
Moving the overhaul to the 18th clears the peak and lets receipts recover first. The contractor has confirmed that date is possible. I have added it to the pre-meeting pack with the effect on generation and stock.

FAQQuestions

Frequently Asked Questions

What is S&OP in power generation?

A monthly planning cycle that brings dispatch, maintenance and fuel plans together, finds conflicts and ends with one plan approved by senior leaders. Gencos often call it integrated planning.

Is S&OP commonly used by generating companies?

The term comes from manufacturing and is not standard in power. The principles apply well, because generation also depends on several plans that must agree.

What are the five steps of the S&OP cycle?

Data review, demand review, supply review, a pre-meeting to resolve gaps, and an executive meeting to decide.

How far ahead does S&OP look?

Typically a rolling 18 months, reviewed every month. Integrated business planning extends this to 24 to 36 months.

Who should own the process?

A planning head usually runs it, with an executive sponsor who chairs the decision meeting and settles trade-offs between functions.

How long does it take to start?

A shared view and a first monthly cycle on one plant typically fit within a 6–12 week rollout. Plan it with our specialists.
