three Massive Inquiries about Power Use in Legal Cannabis Cultivation


Recreational cannabis hits the shelves January 1, 2020 in each Illinois and Michigan. How will the race to marketplace influence power use?

Developing cannabis is an power-intensive method, and as cultivators concentrate on acquiring solution prepared as immediately as achievable, it will be effortless for power efficiency to get pushed to the backburner and power consumption to rise.

Contemplate early adopters like Colorado and Oregon: In Denver, cannabis facilities are consuming four% of the city’s electrical energy, even though Oregon has skilled localized blackouts due to the added strain on the electric grid from indoor cannabis facilities. The Midwest can study from these early adopters to make sure power efficiency targets and grid reliability initiatives are not compromised by this nascent business.

How Significantly Cannabis Will Midwest States Need to have to Make?

The brief answer: most likely additional than we consider. Underestimating demand has been an concern in early adopting states.

A 2014 study estimated Colorado would need to have to make 121 metric tons of cannabis to meet demand. Immediately after legalization, a 2017 study showed that the state really made 301 metric tons of cannabis, additional than double what was initially anticipated.

Illinois and Michigan each have considerably bigger populations than Colorado, so underestimating demand (and corresponding power use), could be an even larger concern in bigger Midwest markets. As a outcome, it will be even additional essential for cannabis producers and their utility service providers to make power efficiency a priority.

How Significantly Power Does It Take to Develop Cannabis?

The brief answer: we do not precisely know.

Although the power impacts from indoor cannabis cultivation are significant—they’re usually compared to information centers in terms of power intensity—we do not know precisely how a great deal power cultivators in Michigan or Illinois will use. Cannabis cultivators have been hesitant to share information on their facilities for at least two motives: marijuana’s legal status at the federal level and a want to shield trade secrets in this competitive marketplace. This tends to make it complicated to establish an business typical power consumption per pound of cannabis flower.  

The uncertainty about power intensity, paired with shaky demand predictions, tends to make it really hard to predict the all round power required to energy the new cannabis markets in Illinois and Michigan.

And increasing power consumption is not just a issue for electric utilities. Growers will need to have additional heat—often from organic gas—to hold facilities at optimal increasing temperatures in the cooler Midwest climate. Utilities will need to have to prepare for extra load development, which can set back power efficiency targets.

How Can Midwest States Curb Demand Devoid of Stifling the Sector?


The Illinois cannabis legislation integrated power efficiency needs for cultivation facilities, which will lead to smarter power use. Nonetheless, utilities will need to have to design and style custom applications to go above the efficiency baseline laid out in statute. The legislation specifies a lighting energy density (primarily requiring the use of LEDs) for cultivation centers and higher efficiency HVAC gear. Since effective lighting is needed, utility lighting incentives will not do a great deal extra fantastic.

There are, nonetheless, possibilities to incentivize dehumidification measures, HVAC program design and style, creating envelope measures and other smaller sized gear. The statute also demands cultivation centers to submit an power report as portion of the license application, which will support utilities forecast demand and recognize power efficiency possibilities for growers inside their service territory. What information is needed in the power report and which measures cultivators will be needed to report on are nevertheless becoming worked out with the Division of Agriculture.

The Michigan legislation does not incorporate any power considerations, so utility applications will be critical to mitigate power impacts.

Beginning Early is Important

After plants are introduced to a facility, power efficiency retrofits are tougher to obtain, so the very best power efficiency possibilities are in the course of the facility design and style phase when gear is nevertheless becoming chosen.  

In either state, sources will need to have to be created to support cultivators design and style additional effective facilities and companion with their utility providers to choose new increasing facilities. 1 concern that has arisen in other regions of the nation is the need to have for utility infrastructure upgrades to accommodate the massive anticipated power requirements at new cultivation facilities. Numerous growers do not aspect these charges into their plans or price range. Utility distribution program upgrades can be mitigated if utilities and cultivators function in tandem early in the improvement of new cultivation centers.


The possible power influence of legal cannabis cultivation is considerable, but Midwest states can reduce increasing pains by finding out from the successes and set-backs of early adopters.

As new applications and sources are created, MEEA will continue to share very best practices with power efficiency stakeholders across the area.
