A model of sustainable commerce, carbon footprint, grid concerns push SoCal weed industry to be more green

A sterile windowless room glows with the light of 32 high-pressure sodium bulbs. For 12 hours a day, the light shines down upon meticulous rows of about 260 flowering cannabis plants.

This is one of the flowering rooms at Canndescent, a Desert Hot Springs cannabis business that operates several cultivation facilities. The company has the dual distinction of being the first municipally permitted cannabis cultivator in California, and the first in the industry to embrace commercial-scale solar.

Canndescent’s CEO Adrian Sedlin said the solar project, which consists of more than 700 solar modules set up on carports, offsets about 30% of the energy used at the facility. The operation allows Canndescent  to sell energy back to the utility, while also providing shade and cooling on the property itself.

Plus, many cannabis consumers desire a green product, Sedlin said.

“It was an absolute alignment of our internal values with the values of our consumers,” Sedlin said.

Cannabis cultivation generated the carbon emission equivalent of 92,660 cars in 2017. That figure is likely to increase as the legal market expands – 33 states already allow use in some form.

But the nascent industry also presents an opportunity to implement alternative energy processes and build a sustainable farming sector from the ground up.

Derek Smith, a cannabis sustainability expert with Resources Innovation Institute, said companies have yet to embrace sustainable practices on a large scale. But the seeds have been planted.

“I’ve never seen a bigger opportunity for an individual industry to make a positive leap from a highly carbon-intensive model to a low-carbon model,” Smith said. “We truly have the opportunity. We actually can show the world a model of sustainable commerce.”

How much energy does it take to grow cannabis?

The energy needs of cannabis cultivation already have presented challenges for municipalities and utilities as more states move to legalize. Oregon saw cultivation-related outages in 2015, shortly after recreational marijuana was legalized, leading officials elsewhere to ponder the need for additional substations, or how to keep their grids alight in the face of increased usage.

In the Southern California Edison service area encompassing the western side of the Coachella Valley, cannabis cultivation facilities use about 235 megawatts a day, or the equivalent of about 100,000 California homes.

System-wide, daily energy use ranges from about 10,000 to 11,000 to as much as 20,000 to 22,000 megawatts, depending on the seasons. That means the energy used by cannabis cultivation facilities could represent 1-2% of overall usage.

In Desert Hot Springs, now home to about 10 dispensaries and 23 cultivation, manufacturing or distribution projects, Mayor Scott Matas said initially there were concerns about whether the SCE grid could support the added load.

But as the facilities have gotten grows underway, some have found ways to limit usage to save energy and money — like Canndescent’s solar panels, or the implementation of LED lights, Matas said.

“If you could go to Las Vegas and see the lights that are used there, and the power that’s used there, I think they can find power to power up our industrial area here with no problem,” Matas said.

At Canndescent, the solar offset allows the company to sell energy back to SCE and recoup money on its energy bills. For its indoor grow facility, the bill could be around $30,000 a month without solar. Since the new solar project that came online in March 2019, the bill is about $12,000, Sedlin said.

Canndescent also takes advantage of an agricultural discount through SCE, which knocks 20% off of the energy costs.

Indoor vs. outdoor grows

Mike Rowe is the vice president of MSA Consulting, a Rancho Mirage civil engineering firm that’s worked with cannabis cultivation businesses on permitting, site design and other planning needs. He said indoor cannabis cultivation facilities generally use about 25 times what a standard industrial development may need.

“We’ve found that they all have their special way of growing, but there is a pretty consistent demand for the power they need,” Rowe said.

Sophisticated indoor grow facilities deploy climate control systems to keep the temperature consistent and humidity in check. The facilities often have ventilation systems and large overhead fans that frequently run to control air flow.

Perhaps most crucially, plants need extensive lighting systems to replicate the sun’s intensity. Bulbs can run for 12 to 18 hours a day, depending on what point in the life cycle the plant is at.

The benefit of the tightly controlled indoor environment is a carefully crafted product that’s been spared the wildcards of weather and pests, ultimately yielding a better output.

“When you grow outside, you can’t get as many crops as you can in a controlled environment inside,” Rowe said.

Rooms are also outfitted with automated temperature and climate controls, which helps cut down potential wasted energy and helps the plants thrive.

A few streets away, Canndescent operates a greenhouse cultivation facility which yields cannabis sold at a lower price point under the name Good Brands.

The mixed-light greenhouse facility incorporates the plentiful sunlight of Southern California, limiting the energy usage from the facility. And the dry desert climate also can work in a grower’s favor due to decreased humidity— the greenhouse also uses an evaporative cooling wall that can chill the facility by 35 degrees. It also doesn’t require the same HVAC or carbon dioxide implementation systems that are used in the indoor facility.

“It’s a much more cost-effective approach, less carbon footprint, but we can still produce beautiful cannabis at the same time,” said Tom Williamson, Canndescent’s operations manager.

While commercial-scale industrial grows run up five-figure electric bills, smaller cannabis grows can also stress power systems.

Kevin Short is the general manger of the Anza Electric Cooperative, which provides power to nearly 700 square miles in Riverside County. The mountainous high country area has long been a haven for cannabis growers, many of whom operated under the medical usage laws that preceded recreational cannabis legalization through the Proposition 64 ballot initiative in 2016.

While there aren’t commercially licensed indoor industrial-sized grows on the co-op’s grid, a Riverside County ordinance allows qualified patients to grow 12 plants, or 24 plants for two patients on the same premises.

But in the post-Prop 64 era, Short said the system has seen an increase in overloads on the transformers.

“Growers will move into an area or into a service location, not tell us how much load they’re adding onto the system, and eventually overload the transformer,” he said.

Repairs can cost the co-op precious time and money. He recommends anyone who plans to start growing in the area run the plans by the co-op so they can be sure to support the service.

Jazmyn McCammon, a board member of the High Country Growers Association who gets power from the co-op, grows 12 plants that she mostly gives away and makes solvents with.

Her operation is as natural as it gets: Plants are watered with a closed-loop system that avoids drawing well water, and she creates plant food out of fermented herbs from a garden.

She said she tries to be “a good neighbor” when it comes to power usage: that means running the lights during off-peak hours, like midday or the middle of the night.

“We go around that (peak hours) whenever we do use our lights and our power,” she said.

McCammon likes to think of the emerging cannabis industry to the beer industry: there are both large domestic brewers, and craft breweries with specialty products. And she sees California as a place where the omnipresent sun could contribute to off-grid solar-powered properties, and outdoor grows, should they be permitted.

But the area is also becoming a hotbed of enforcement: Sheriff Chad Bianco has prioritized cracking down on illegal grow operations, with deputies linking some operations to increased criminal activity and organized crime.

McCammon is concerned that Riverside County is punishing law-abiding growers by not permitting legal operations fast enough, and restricting methods of cultivating.

“The ultimate answer is outdoor growing,” she said.

Building a future on alternative energy

Smith, the sustainability expert from RII, said more data is needed to determine the most efficient set of indoor environmental conditions for a grow environment.

While some technology that could use less energy is becoming more common-place — like LED lights that could use 40% less energy than other bulbs — such improvements won’t make a difference if inappropriately used, Smith said.

“We’re seeing the opportunity of increased efficiency being left on the table, and it’s primarily because everybody needs more data to guide their decision-making,” Smith said. “This whole phenomena of growing plants in buildings is new to everyone.”

As more states move to legalize, they’re finding new ways to address energy use. In Illinois, where legalization will take effect in 2020, lawmakers this year approved a plan to set limits on how much electricity and water cannabis cultivators can use.

Canndescent’s CEO Sedlin said more cannabis facilities would be able to make sustainability-related improvements if the cannabis industry had access to traditional banking.

Even though dozens of states have legalized access to cannabis in some form, it’s still illegal to possess or sell it under federal law. That means banks who take in money associated with cannabis sales could be at legal risk.

“For us this was a priority, so we made it happen and we were able to secure private loans,” he said.

Changes could be coming soon; the Secure And Fair Enforcement Banking Act would protect banks that work with state-compliant cannabis businesses from federal penalties. It passed the Democrat-controlled House of Representatives in late September and still must go through the Republican-controlled Senate.

Sedlin said banking reforms are necessary for companies in the cannabis space who want to make big investments in alternative energy. While the solar offset is valuable for the company and, as Sedlin puts it, “the right thing to do,” private financing comes at a hefty cost that not all companies can swallow.

“I’m paying double digits (for interest rates),” Sedlin said. “It’s a joke. But again, it’s the right thing to do … Our consumers know we’re serious about being a positive force. Our company name, Canndescent, means to project light, and we’re very serious about doing that top to bottom in the company.”

Most States Legalizing Marijuana Have Yet to Grapple with Energy Demand

Oregon, Massachusetts and Illinois are among states taking steps to regulate energy use, according to a new report

Cannabis cultivation in the United States this year will consume 1.8 million megawatt-hours of electricity, about as much as the nation’s 15,000 Starbucks stores.

And next year it’ll be even more, according to a report from analytics firm New Frontier Data estimating just how much power it takes to produce the nation’s cannabis crop.

Yet even as they’ve welcomed it into the regulatory foldstates legalizing cannabis so far have done little to limit or even track the huge amounts of energy needed to grow it indoors. Among the 11 states to permit recreational use of cannabis, only Massachusetts and now Illinois, which did so this week, have included energy-efficiency standards for indoor cultivation, a practice that requires nearly nonstop use of lights and various heating, ventilation and air conditioning systems.

One other state, Oregon, requires simply that growers estimate and then report back on their energy use. Even this small step will help regulators there and in other states to better manage an industry whose electricity demand has long been kept as hidden as its product, says report co-author Derek Smith of Resource Innovation Institute, a nonprofit organization that promotes resource conservation in the cannabis industry.

“This is critically important, and every state should consider that,” Smith told FairWarning. “This industry has very little data historically because growers were concerned about sharing information about how they were using energy because they were hiding from the law.”

The report’s estimate of massive power demand includes only the legal stuffboth medical and recreational. Add in illicit production–some of it likely to become legal as more states authorize pot growing–and electricity use nearly triples.

Meanwhile electricity use also continues unchecked in most cannabis-legal states including California, the world’s largest cannabis market and producer of the majority of the nation’s crop. Its Bureau of Cannabis Control won’t begin asking cultivators for data on energy use until 2022, and hold them to statewide standards for renewable energy starting in 2023.

“It’s a marathon,” says Josh Drayton of the California Cannabis Industry Association, a trade group. “But the more that these issues get brought to the table, the more involvement from energy suppliers and from the industry, the more data and research that can be put out there — that’s really what’s necessary to bring change.”

Using data reported privately by 81 cultivators in nine states, the report’s authors calculated that among the three main methods of cannabis cultivation, indoor accounts for at least 60 percent of all electricity use.

Greenhouse cultivation, which requires less lighting but still involves heating, cooling and ventilation, consumes about 37 percent of the total. Outdoor farming represents the remainder, less than 3 percent.

The authors estimate it takes 18 times more power to grow a gram of cannabis indoors than outdoors. Yet for a variety of reasons including quality control, safety and security concerns, and nuisance issues related to odors and nighttime lighting, outdoor cannabis cultivation isn’t ideal everywhere, says Beau Whitney, a senior economist with New Frontier Data.

Massachusetts is one of those places, due in part to its climate and population density. But state regulators still encourage outdoor growing through discounted license fees for the express purpose of reducing energy demand, notes Sam Milton of Climate Resources Group, a Boston-based consulting firm that has partnered with Resource Innovation Institute.

For indoor growers, Massachusetts’ rules cap power use on lighting at 36 watts per square foot of plant canopy, or 50 watts per square foot for smaller operations.

In Illinois the new law signed this week by GovJ.B. Pritzker, is even stricter, applying the limit of 36 watts per square foot to all indoor farms, regardless of size.

Both states effectively prohibit the use of any lighting technology that draws more power than efficient light-emitting diodes, or LEDs, Milton says. Though more expensive than standard high-pressure sodium lamps, LEDs last longer and can reduce electricity usage by 40 percent.

The two states also have energy-reporting requirements similar to Oregon’s.

The emerging industry is already confronted with a patchwork of state-level regulations governing pesticides and other potential contaminants including metals, microbes, and solvent residues. In the case of electricity use, Milton says he believes a better alternative will be for the U.S. Department of Energy to aid the industry in developing new standards and efficiency measures.

“These facilities are so energy-intensive, and they’re proliferating, and they’re largely unregulated. I see that sector as something that really needs a lot of attention,” he says. “Without the feds coming in and providing that overarching support, it’ll have to be a state-by-state basis, which is kind of clumsy.”

Monitoring Systems for Outdoor Hemp Cultivation

With the increasing popularity of hemp cultivation outdoors and in greenhouses, new monitoring systems are entering the market to meet the needs of hemp farmers.

Hemp farming is fast becoming a popular industry due to its wide range of therapeutic and manufacturing uses. Many systems already exist for monitoring indoor hemp cultivation facilities, such as Urban-Gro and Braingrid, bringing novel, Internet of Things solutions into the hemp space.

Now that hemp is a fully legal agricultural commodity, more farmers are choosing to grow hemp outdoors. Within the CBD oil extraction industry, hemp is often found growing in a greenhouse. Both options are rising in popularity for hemp, meaning that monitoring systems for use in these environments are necessary.

Learn the requirements for effective monitoring systems, and take a look at some of the key players within the hemp cultivation industry.

FEATURES TO LOOK FOR IN A MONITORING SYSTEM

A remote monitoring system is designed to safeguard against prolonged environmental conditions that could damage or destroy an entire crop. A remote monitoring system must be able to:

  • Track near real-time changes in ecological conditions.
  • Communicate alerts to the user independent of the Internet or an Ethernet cable (e.g., enabled via a secondary cellular network for redundancy)
  • Continue to operate in the event of a power outage (must have a battery backup system)

Depending upon the size of the operation, a monitoring system able to analyze different zones within the crop may be desired. If hemp is being grown in a greenhouse, choose a monitoring system that can also be connected to any HVAC or lighting equipment to monitor performance, and check for failures.

BENEFITS OF AUTOMATING HEMP CULTIVATION

Monitoring systems are a core component of any automation system, as data must first be collected before an equipment or environmental decision can be made. Moving toward automation of the growing environment can accomplish the following:

Reduce the cost of labor

Automating essential tasks allows for less personnel, or grants staff to devote more of their time to other areas of interest, such as R&D or marketing efforts.

Increases yield and product quality

Measuring environmental conditions within a grow operation allows the farmer to improve their methods based on analyzed data and trends. This optimization often results in improved outcomes as related to quantity. Recipes for specific types of hemp can be created, ensuring repeatability in product quality.

Eliminate guesswork

Through analyzing cultivation data, the grower can make informed operational decisions. Changes in farming practices will only be based on evidence, rather than speculation. Sugarmade AI Cultivation Monitoring System

In May of this year, Sugarmade announced a new initiative to develop a simple, AI-based technology to monitor the cultivation of outdoor hemp. Sensors will be placed at appropriate locations throughout a hemp field and will gather data such as temperature, relative humidity, and soil moisture.

This monitoring system will be based on narrowband IoT technology, which is a type of cellular communications network. Advantages of this technology include a wider coverage area than other mobile networks and long battery life.

Sugarmade has not yet made public a timeline for the development of this technology.

SENSAPHONE REMOTE MONITORING SOLUTIONS

Another cellular-based system, the Sensaphone remote monitoring devices are specifically designed for use in a greenhouse environment. Sensors are placed throughout the greenhouse, and temperature, ventilation, CO2, and relative humidity data is collected. The user can set threshold limits for each parameter and is notified via a call or text if any variable falls outside the threshold limits.

Alerts are also received in the event of a power outage or equipment failure. Data is backed up on the cloud for redundancy, and the device is equipped with an internal rechargeable battery for redundancy in the case of a power outage.

LINK4 CLOUD-BASED GREENHOUSE CONTROLS

In addition to offering an automatic dosing system to ensure consistent fertigation, Link4 has also created a class of crop monitoring systems designed for greenhouse growing. These systems control as well as monitor, and can manage up to 24 HVAC and lighting devices.

AUTOGROW PROTECTED CROPPING

A form of outdoor growing, protected cropping allows plants to grow in a fully outdoor environment but with the added benefit of minimal structures offering protection from the elements. Examples of such enclosures would be hoop houses, tunnel houses, and canopy protection.

Autogrow’s system allows the hemp farmer to monitor and control variables such as irrigation, fertigation, run-off, and root zone. The user receives an alert in the event of a problem and can manage the system remotely from their smart device.

How Much Electricity Does It Take To Grow Marijuana? Colorado Cities Are Finding Out

Colorado’s appetite for lighting up requires a lot of lights, it turns out.Licensed marijuana growers traditionally cultivate their products indoors under very bright lights that suck a lot of electricity. With the release of the federal government’s Clean Power Plan looming, cities across the state are working to reduce their carbon footprint. Part of those efforts include persuading grows to reduce their power consumption.

Between 2012 and 2013, the latest data available, electricity use increased by 1.2 percent across the city and county of Denver. Commercial marijuana grows were responsible for nearly half of that uptick.

“We’re very keen to see what is increasing energy use, and to have half of that coming from the grow industry is definitely something we pay attention to,” said Sonrisa Lucero, a strategist for the Denver’s Office of Sustainability.

Denver marijuana grows used just 1.85 percent of the city’s overall electricity in 2013. But any uptick matters because the city set a voluntary goal to prevent total energy consumed from rising past its 2012 use levels. Lucero’s job is to make sure that energy efficiency is top of mind for new residents and businesses.

The city is working with marijuana grow operations to lower their electricity use. Or the industry may sort itself out: A growing number of outdoor and greenhouse grow operations in Colorado are emerging that could make indoor grows obsolete — or at least, less cost effective.

A $12,000 electricity bill

To understand just how much energy it takes to grow marijuana indoors, look no further than Colorado Harvest Company’s Flower Room No. 1.The room has dozens of green plants thriving underneath 22 1,000-watt lamps hanging from the ceiling. Each is the size of a small card table. An air-conditioning system prevents the lights from overheating.

“Running a cannabis company with indoor production means that you’re going to use more than your fair share of electricity,” said Tim Cullen, the company’s owner.

Cullen’s monthly electricity bill for the 10,000-square-foot warehouse runs a cool $12,000. Another marijuana grow reports spending nearly twice that amount. Cullen said he’s tried to reduce electricity use by using LED lights currently on the market, but they haven’t produced the results he needs.

“We just can’t suffer the losses of having a lower energy bill, but then not producing flowers,” he said.

New LED technology under production could change this picture. But Cullen isn’t waiting for that to happen. Instead he’s building a greenhouse in Denver to commercially grow marijuana. From start to finish, the planning and construction is expected to take about six months.

Greenhouses blooming in Pueblo

Denver has about four commercial marijuana grow greenhouses. But Pueblo is leading the charge in the state, with 16 and counting. Some are small, but others cover as many as 50 acres.

Chris Markuson, director of economic development and GIS for Pueblo County, said shifting priorities are changing how and where marijuana is grown.

“At first the assumption was that the grow operations had to be tightly secured and hidden from public view,” he said. “Because the temperament of the community–and the society as a whole–has come around a little bit, the grow operations are not really seen with negative light. At least they’re not in Pueblo.”

It helps that Pueblo has marketed itself as a business-friendly lower-cost location to cultivate marijuana.

With about 30 marijuana grow businesses overall, Markuson said the majority are using “Pueblo sunshine” to grow product.

Energy use in the area is evolving with the industry. According to Black Hills Energy, which provides power to the city of Pueblo and parts of Pueblo County, 10 grow facilities used 2.1 million kWh in 2014. That’s 0.1 percent of the energy that Black Hills delivered to its Pueblo coverage area.

Laying the groundwork

As the marijuana industry evolves, Colorado cities are deciding how–or if–they want to manage the growing energy demands from the industry.

Denver isn’t considering regulations for the marijuana industry, but pushing LED lights to grows. In Boulder, the city and county are setting measures to require businesses offset their electricity use via subscription of renewable energy credits — things like community solar garden memberships.

Xcel is reportedly working with marijuana growers to update lighting so they’re as energy efficient as possible.

The attempts by utilities and cities fit into a larger movement under way right now, said Howard Geller with Boulder-based Southwest Energy Efficiency Project.

“We can have that economic growth without electricity use increasing,” he said. “That’s going to be beneficial economically and that will help us achieve our environmental goals.”

Denver and Boulder’s work with marijuana and other businesses could be a good warm-up lap for what’s to come. The Clean Power Plan rule, expected to be finalized later this summer, will put even more pressure on states to reduce carbon emissions. Some of that reduction will come from changing where our power comes from. But Geller expects another significant portion to come from things like switching out the lightbulbs.

“Energy efficiency is a strategy that can be implemented very quickly in terms of ramping up rebate and financing programs, education efforts,” said Geller. “Whereas building new power plants–or retrofitting old power plants–that kind of initiative will take years to implement.”

Marijuana Growers Now Qualify For Energy Discounts In California

Agricultural Cannabis Growers Now Eligible for PG&E Ag Rate and Programs

Release Date: March 01, 2017
Contact: PG&E External Communications (415) 973-5930

SAN FRANCISCO, Calif. — While recreational marijuana cannot be sold in California until January 2018, existing medical marijuana growers and future recreational marijuana growers will be eligible as of March 1 for PG&E’s agricultural energy rate.

The passage of Proposition 64 in November 2016 allows the state to license and regulate recreational marijuana cultivation and businesses.

“Cannabis is a legal crop in our state, like almonds and tomatoes. Agricultural growers now will be eligible for the same rate and energy efficiency programs as farmers of other crops,” said Deborah Affonsa, vice president of Customer Service at PG&E.

PG&E customers are eligible for agricultural energy rates if they have received a permit from their local jurisdiction for the cultivation of cannabis and if 70 percent or more of the annual energy use on the meter is for agricultural end-uses such as growing crops, pumping water for agricultural irrigation or other uses that involve agricultural production for sale which do not change the form of the product. The agricultural energy rate applies to both customers who grow cannabis outdoors and those who grow indoors in commercial greenhouses.

The agricultural energy rate does not apply to residential customers who can legally grow up to six marijuana plants inside a private residence per the state Adult Use of Marijuana Act.

Previously, medical marijuana was not considered an agricultural product by PG&E, and growers were not eligible for the agricultural energy rate. Because medical marijuana can be grown and sold in California currently, licensed growers of medical marijuana are immediately eligible for the agriculture energy rate.

Cannabis growing operations can use an extremely large amount of electricity and are considered to be equivalent to other energy-intensive operations such as data centers.

“We’ve met with representatives of the emerging legal cannabis industry and listened to their needs. We are here to help our customers make smart, efficient and affordable energy choices. Now that cannabis is in California’s future, our next step is to work with these new agricultural customers and make this industry as energy efficient as possible,” said Affonsa.

PG&E’s agricultural rates are under the jurisdiction of the California Public Utilities Commission and the state of California.

Agricultural customers with questions about rates, rules and energy efficiency programs can learn more at pge.com/ag or contact PG&E’s dedicated Agricultural Customer Service Center at 1-877-311-3276.
