Energy now plays a direct role in crop performance, production consistency, and the ability to meet contracts. It is no longer just about what you spend. It is about what you grow. The conversation is no longer about how to reduce energy costs. The real question is how energy can be used to protect and enhance production. These themes were recently shared with more than 130 growers and industry professionals at the ACT Grower Summit in Leamington, Ontario.
Every energy decision impacts the crop
Modern greenhouses depend on energy for lighting, heating, irrigation, CO₂ dosing, and climate control. When energy use is reduced without a clear strategy, the effects show up quickly in the crop. Reducing lighting to cut costs may deliver short-term savings, but it often leads to slower growth, delayed harvests, and lower yields. Those impacts are difficult to recover from and can put contract commitments at risk.
In this environment, energy decisions must first protect crop development. Cost optimization comes second.
Rising complexity in an electrified greenhouse
Greenhouse operations are becoming more electrified. LED lighting, electric boilers, and heat pumps are increasingly common. While these technologies improve efficiency, they also increase dependence on the electrical grid.
At the same time, electricity pricing has become more volatile. In many regions, growers must deal with variable pricing, demand charges, and limited grid capacity.
One of the most important factors is peak demand. In markets such as Ontario, a grower’s highest short-term electricity peak in a month can significantly impact the total energy bill. A single spike in usage can set costs for weeks.
This creates a new challenge. It is no longer just about how much energy you use, but when and how you use it.
Smarter use, not less use
When energy prices rise, the natural response is to cut back. In greenhouse production, that approach has limits.
Crops require a certain amount of light. That requirement does not change. What can change is how that light is delivered.
By spreading lighting over a longer period and avoiding simultaneous peaks, growers can maintain required light levels while reducing exposure to high costs. The total energy input remains similar, but the cost structure improves.
The key is shifting from reducing energy use to optimizing energy timing.
Too much to manage manually
Managing energy today involves multiple variables. Weather forecasts, natural radiation, electricity prices, crop targets, and contract obligations all influence daily decisions.
Handling all of these factors manually is no longer realistic. Even experienced growers cannot consistently optimize across so many moving parts.
This is where a more data-driven approach becomes essential.
Moving toward intelligent energy management
A growing number of growers are adopting more predictive and automated ways of managing energy. By using available data and integrating systems, it becomes possible to plan ahead rather than react in the moment. Lighting can be scheduled based on both crop needs and energy pricing. Peaks can be avoided before they occur. Crop targets remain the priority, while costs are optimized around them.
To make this possible, the greenhouse must also be connected to the outside world. Access to day-ahead electricity pricing, weather forecasts, and utility signals allows growers to anticipate changes rather than respond too late. Open, connected platforms such as Priva One, combined with integration capabilities like Priva Integrations, enable growers to bring these data streams together and act on them in real time. This approach allows growers to maintain consistency in production while reducing financial risk.
Energy as Part of the Whole Operation
Energy decisions do not stand alone. They influence climate control, irrigation, and even labor planning. For example, changes in lighting affect heat levels, which in turn impact climate strategies. Irrigation timing may shift based on plant activity. Production timing can influence labor requirements.
Treating energy separately from these processes leads to inefficiencies. Integrating energy into the broader production strategy creates better overall results.
Building Resilience for the Future
Energy markets are unlikely to become more predictable. Volatility, electrification, and increasing complexity are here to stay.
For growers, this means energy management must evolve. The focus should move from short-term cost cutting to long-term production stability.
The growers who succeed will be those who use energy as a tool to protect their crop, manage risk, and maintain consistent output.
At Priva, we see this shift already underway, with growers adopting more connected and data-driven approaches to align energy use with crop performance. Because in today’s greenhouse, energy is no longer just a cost.
It is a core part of the crop strategy.
