“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.”

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

• 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

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
