Energy data in greenhouse horticulture: steering in a moving market
The greenhouse's inverted profile is not a drawback but an opportunity, provided consumption, generation and price come together in one view.
No sector lives as close to its energy consumption as greenhouse horticulture. Lighting, heating, cooling and CO2 dosing together determine both the crop and the cost price. Many growers therefore know their consumption better than the average business owner.
Yet the playing field is changing fast: hourly prices swing more sharply, export to grid is not always rewarded and grid capacity can no longer be taken for granted. Growers who have their energy data in order at quarter-hour level can steer on that movement instead of being surprised by it.
The inverted profile of the greenhouse
Where most businesses peak during the day, a grower using supplemental lighting runs at full power at night and in winter. That inverted profile has consequences: for greenhouse horticulture, the most expensive and the cheapest hours of the market fall at different moments than for the rest of the business community.
That is not a disadvantage but an opportunity. Lighting is in many cases one of the most shiftable large consumers there is, provided you know precisely what happens per quarter hour and what the crop allows.
Steering starts with bringing data together
In practice, crop data sits in the climate computer, consumption data with the metering company and price data in the market. As long as those worlds remain separate, steering stays stuck on experience and gut feeling.
- Place the consumption profile per quarter hour alongside the hourly prices: you will see which running hours structurally fall in expensive moments.
- Compare sections or greenhouses with each other: identical crops should have comparable profiles.
- Monitor the load on the grid connection: if you are close to your contracted capacity, you want to see peaks coming rather than establish them afterwards.
- Flag deviations automatically: a screen, valve or pump behaving differently gives itself away in the profile first.
Export to grid and congestion call for the same insight
For businesses with solar on the roof or their own generation, the same principle applies in reverse: exporting to the grid at moments when the grid is full or the price is low yields little and can even cost money. The quarter-hour profile shows when self-consumption, storage or curtailment is wiser than feed-in.
And anyone who wants to expand, electrify or consider a new cultivation strategy needs the profile to know whether the current grid connection can handle it.
Conclusion
Greenhouse horticulture has, like few other sectors, the flexibility to steer on the energy market. The condition is that consumption, generation and price come together in a single picture at quarter-hour level. Would you like to know what your profile makes possible? Book a no-obligation call.
