Saving money at season start-up and shutdown
Knowing when your meter is scheduled to be read may save you the demand charge for an entire month.
Most Saskatchewan rinks have only one meter which is not disconnected during the summer months. As an example, if you start your ice plant on September 15th, and your meter is read on September 17th, you will be charged the full demand charge for the billing period ending September 17th, even though you only used the ice plant for two days.
If you waited until after the meter was read on September 17, then started the ice plant, you would save one full month of demand charges contributed by the ice plant.
Your local SaskPower District Office can provide you with an approximate date for when your meter will be read.
Example 1.3 - Start-up and shutdown of the compressor
At the start of the season, if the lighting, heating and other electrical loads in the building totaled 50 kVA and you were operating a 60 hp ice plant (where 1 hp is approximately equal to 1 kVA), you could save about $580 in demand charges plus taxes by waiting two days to start the compressor.
The same is true at the end of the season. If the meter will be read on April 17, try shutting the ice making equipment off on April 16. If the plant runs until April 19, you would be charged the full demand charge in the next billing period for only running the plant for an extra couple of days.
Shutting off the plant on April 16 could save you $580 in demand charges.
