Not all downtime is the same
Not all downtime is the same
When you operate RES assets, “downtime” actually comes in three very different flavours:
When you operate RES assets, “downtime” actually comes in three very different flavours:
Emergency downtime
Emergency downtime
The asset is in trouble: something overheats, a component fails, safety limits are breached.
Response: Stop now, fix now.
Priority: safety and asset protection, not optimisation.
Reality: this is where you have to react, not choose.
Scheduled maintenance
Scheduled maintenance
Regular service based on hours, days, or OEM recommendations (e.g. every 6 months / 5,000 operating hours).
The what is fixed (scope of work).
The when is often flexible – but in practice, usually set by technician availability and OEM calendars, not by market conditions.
Preventive maintenance
Preventive maintenance
You’ve spotted something early:
Anomaly in SCADA
Sensor drift
Performance degradation trend
Response: “It’s not broken yet, but it will be – let’s fix it before it fails.”
Where the lost revenue hides

You can’t optimize emergency downtime – that’s non-negotiable.

But you can optimize:
Scheduled maintenance windows
Preventive interventions once an issue is detected
And that’s where most portfolios quietly lose money.
Today, those windows are usually picked by:
Today, those windows are usually picked by:
When the maintenance team can come
When there’s a generic “low season”
When the OEM has a slot

Instead, they should be scheduled by:
When is it cheapest (in revenue terms) to lose this asset for a few hours

What we do differently
What we do differently
We simply help you choose the window for type 2 and type 3 downtime based on:
Production forecasts (how much will this asset produce per hour?)
Price forecasts (what is each MWh worth in each hour?)
Contract exposure (PPA, merchant, imbalance, penalties)
From there, we identify:
From there, we identify:
The optimal window where lost production × price is lowest
Alternative windows if weather or market conditions shift
The true cost of doing it “next Tuesday at 09:00 because the team is free”

Scheduled & preventive downtime: aligned with your revenue stream, not just your calendar.
