Energy Analysis

Snowmaking Efficiency Calculator

Welcome to the Snow Economics System Energy Analysis page

Learn how HKD Technology can reduce your snowmaking energy costs while increasing the productivity of your snowmaking system.


Please fill in the requested data about your resort and the analyss assumptions which include certain aspects of your snowmaking system and energy costs. Also, please provide the length and width of a trail at your resort on which you currently make snow, as well as the required annual man made snow depth for this trail.

With this information we can generate an estimate of your Acre Foot energy costs using the following snowmaking technology: conventional air/water snow guns, HKD SV10 technology, and Fan Gun technology.

We will provide you with an Operating Cost Estimate for that trail, a Capital Cost comparison for these three different technologies, as well as a Payback Analysis comparing the installation of HKD SV10 towers to Fan technology on this terrain. Finally, we will provide a System Productivity Analysis which will display how to maximize your existing pumping capacity with the minimal amount of compressed air.

I. Analysis Assumptions:
1. System Water Capacity (GPM)
2. System Air Capacity (CFM)
3. Trail Length (ft)
4. Trail Width (ft)
5. Trail Acreage (Acres)
6. Snow Depth (ft)
7. Energy Cost ($/kwh)

The operating cost estimates and payback analysis use flow data for the various technologies assuming the temperature mix outlined as below.
Your resort average temperatures may differ - we would be glad to refine the analysis for you if necessary

Snowmaking Temperature Mix
26 F - 28 F Wetbulb 15%
24 F - 26 F Wetbulb 25%
20 F - 24 F Wetbulb 35%
11 F - 19 F Wetbulb 15%
Below 10 F Wetbulb 10%
II. Energy Cost($)/ Acre Foot of man made snow for:
Air/Water, Low E HKD SV10 & Fan technology

*The Average Cost $/AF uses the blend of temperatures outlined in the Snowmaking Temperature Mix as above.

Fan Cost assumes all high voltage electrical wiring is in place.
If on-hill wiring and associated costs are needed capital cost must increase accordingly.
