“These facilities use more energy per square foot than anything other than maybe a few in industrial processing. It blows away hospitals, laboratories...it might be on par with extreme data processing centers, like a Google or a Facebook.”

CHP for Cannabis • Reduced Energy and Operating Costs
• On-Site Power
• Waste Heat Capture / Reuse
• High level of Environmental Control
• Additional Sustainability Benefits • Sequestration of CO2 for grow environment • Generation of New Water, Lower Water usage plus Full Recapture
Sustainable Benefits of Waste Heat Recapture • Thermal powered chillers – 90% reduction in electricity used
• Waste Heat utilized to provide Heat • Radiant floors
• Forced Air
• No need for natural gas boilers or unit heaters
• Thermal powered Dehumidification • Uses 80% Less Electricity
Tri-Gen plus CO2

Impact of CHP and CO2 Capture on Greenhouse Gases
Additional Sustainable Benefits • Engine exhaust is condensed to capture H2O during CO2 process
• Proprietary thermal water treatment to replace Reverse Osmosis • 95% yield vs. 35% (single pass) for RO • Lower electrical usage
• Dehumidification process recaptures H2O
• Thermal DeHu filters the air while killing pathogens
• Closed loop systems limits both bugs and pathogens

Additional Considerations • Distributed CHP power lost access to ITC at the end of 2016
• Individual states offer significant incentives for distributed CHP
• CA – Self Generation Incentive Program
• CHP can be combined with other renewable technologies to improve sustainable impact
• Use of batteries improves the overall efficiency a Gen set as they can run at higher efficiency levels and be turned off for periods of battery power
Solar Generation + Battery Storage for Cannabis Growers
Mike Ashley MWBattery
Cannabis growers face an electricity problem

A 10,000 sq ft indoor grower can easily spend >$10,000 / month on electricity…
Electricity Other overhead costs
…from kWh used, demand charges, and stress added to the grid
Demand charge: $ / kW of your peak power use

• The technology has matured
• Streamlined processes and economies of scale have led to significant reductions in manufacturing cost
• Achieving “grid parity” in many parts of the U.S.
Solar panels take up space; what are your options?

10,000 sq ft of solar panels will generate ~25,000 kWh per month
Batteries enable greater use of renewables, “peak shaving,” and provide backup power

Use battery
Reliable backup power
• Disconnect from the grid in the event of power loss
• A large battery can power a 10,000 sq ft full indoor facility for >24 hours on a single charge
• Unlike diesel generators, batteries are maintenance-free and do not require consumable fuel
Tradeoffs in battery chemistry
MWBattery P O W E R T H R O U G H
Lithium ion batteries Flow batteries
• 1.25 – 1.5x lower cost per kWh
• ~Half the physical size per kWh
• >2x greater lifetime
• More environmentally friendly materials
Separation of Li+ and electrons Water streams containing (1) zinc and (2) iron compounds “flow” past each other
Incentives and grants reduce the cost of generating your own clean energy
MWBattery P O W E R T H R O U G H
Federal incentives
• 30% investment tax credit on solar
• 30% investment tax credit on battery storage, as long as >75% of energy used comes from solar
• Sen. Michael Bennet (D-CO) has introduced legislation to include ITC for all energy storage
State incentives (CO)
• State rebates
• Renewable Portfolio Standard – CO must be 30% renewable by 2020
• State sales tax exemption on renewable energy purchase
• Property tax exemption from increased value due to energy resources
Grants
• Regularly opening and closing
• An active grant call: CA dedicated $44MM to the construction of C&I-scale “microgrids”
Some parting thoughts • On-site clean energy generation is an investment that pays for itself
• Finite payback period vs. small monthly savings with a lease
• Federal/state governments and utilities make it easier to install energy resources
• Reduce dependence on the utility; cord-cutting is possible
• “Grown using clean energy” as a point of competitive differentiation
