Indoor Growing Warehouses
Commercial Greenhouse Generators
Commercial generators for greenhouses and indoor growing operations are a necessity because large scale off-grid cultivation requires consistent electricity loads to power proportionate amounts of cooling, heating and to properly maintain automation:
- Climate Controls
- Irrigation Systems
- Dosing Pumps
- Horticultural Injector Systems
- Fertigation Systems
- Hydroponic Systems
- Fans And Air Handling
- Indoor Grow Lightning
- Humidification and Cooling Systems

Greenhouse growing on an industrial scale presents a challenge to producers to build and scale their power needs to meet the high demand. As that power demand increases so do the risks when relying on the utility power grid. Some grow operations are located in remote, off-grid areas where power is not available or is slow to recover from power outages. As with any automation system, downtime can destroy yield and risks damaging computer systems and other sensitive equipment. It is not just the grow lamps that must stay on.
As of 2016, Cannabis is illegal under federal law, but marijuana cultivation has been legalized for medical or recreational use in 23 states and the District of Columbia. According to a 2012 report from Mountain High Organics, "Energy costs for indoor production cost $6 billion a year - six times the power needs of the entire U.S. pharmaceutical industry. A single marijuana growhouse has the same power needs of a similarly sized, energy-greedy data center."
Marijuana growing may be the next great energy hog but the green sustainable farming model has been consistently growing its onsite energy requirements. The need for that power to be protected and consistent for extended periods of time is an operational challenge.

Indoor Growing Facilities
In modern indoor growing, innovation is not unlike the requirements of a data center. Investors in industrial cultivation will be concerned about uptime guarantees and whether the equipment investment is properly protected. The cost of backup or long term continuous power can be mitigated by properly sizing load and taking advantage of long term leasing, trade ins or buy backs, and the availability of high quality pre-owned power equipment.
A common example in new grow operations, "My local utility will not be able to get me the 1500Amps 480V service I require for 18 months? What are my options?" Depending on the location and the size of the load, a mobile diesel unit can provide prime power until the utility power is available. This unit can be rented or purchased and then sold back to us in trade for a more permanent solution.
Mobile Diesel Generators
Mobile diesel generators for standby power backup applications that will need to meet local air quality board and sound limitations. Diesel fuel driven generators provide a low initial install cost, are simple in design, easy to operate and maintain.
Natural Gas or Propane Generators
For continuous power in grow operations, natural gas or propane generators are often the preferred choice, especially in off-grid locations or to provide supplemental power to combat expensive utility rates. Natural gas driven gensets have the best fuel to cost efficiencies, and after initial purchase have the lowest operating costs when the grow operation requires high hours from the generator. The emissions are much lower and there is potentially no transportation cost for fuel with various types of gaseous fuels.
Power Plants
Multiple generators in megawatt sizes to provide combined heat and power configurations. Heat and power cogeneration systems (CHP) can achieve high levels of efficiencies through heat extracted from the exhaust gas and engine cooling system. CHP plants include multiple generator sets, exhaust gas systems, SCR systems and heat exchangers. These genset configurations can increase CO2 levels for boosted plant growth and possibly supply electricity into public grids.
Precision Humidity and Cooling Equipment
Refurbished air humidification and temperature controls for grow rooms that need to automatically deal with heat generated in plant production as well as extreme climates where the grow room or greenhouse is located. Precision cooling in multiple tons is designed to run 24/7 with accuracy down to the degree.
UPS Backup Systems
A new or refurbished UPS System to protect and provide inline power while a standby diesel generator starts up and takes the load. A UPS battery protects monitoring systems, computers, climate and irrigation automation programs and much more.
