Project Background

Koach Grow House is an innovative greenhouse project located in the Inland Empire region of California, with a focus on cultivating medicinal marijuana. Serving as its initial phase, this greenhouse complex has plans to expand through the incorporation of three additional phases.

This project has been strategically positioned in California, a state that has experienced a heightened interest in maglev technology due to the significant peak-hour electricity rates charged by local utility companies.

Project Description

The Koach Grow House poses a continuous 24/7 challenge for greenhouse cooling, necessitating innovative energy solutions.

This facility has implemented a 1 MW CHP system, which stands as a crucial component for the daily operation and success of the plant. The CHP system functions as the primary energy source and currently generates over 100% of the facility’s electricity requirements.

The core of the project revolves around the utilization of a microturbine for on-site electricity generation. Concurrently, an absorption chiller will be seamlessly incorporated to produce chilled water during daytime hours.

Remarkably, during off-peak nighttime hours when utility electricity costs are merely 6 cents/kWh, the microturbine operation is suspended, enabling BROAD Maglev chiller to smoothly take over. This dynamic approach ensures optimal operational costs and highlights the flexibility and adaptability of the cooling system.

Project Value

Koach Grow House employs BROAD maglev chiller during off-peak hours, conserving energy by not operating the absorption chiller during this period. As a result, the absorption chiller operates for a maximum of 4380 hours and saves 6342 MMBTU of fuel by reducing its use during off-peak hours. The system achieves a carbon dioxide reduction of 822 tons*, which is comparable to removing 163 cars from the road each year*, or equivalent to the annual greenhouse gas emissions generated by 87 homes*

* Results are based on the US EPA CHP Energy and Emissions Savings Calculator, which may vary from the actual operation data.

Project Highlight

The Koach Grow House project signifies a noteworthy achievement for BROAD as it introduces its maglev units to the US market.

Located in California, where the appeal of maglev technology has risen due to the steep electricity rates during peak hours established by local utility companies.

Beyond its role as a marketing hub for Maglev technology in California, it is anticipated to accelerate the adoption of this technology nationwide. This pioneering initiative harmonizes seamlessly with the burgeoning trend toward energy-efficient and cost-effective cooling solutions.
