Electricity (Hydro) Savings
REALice saves electricity (hydro). Because of the changed properties of the water, which becomes denser and freezes faster, using less energy to freeze and to stay frozen too, operators are required to reset their brine/glycol settings 3-5°F warmer. This results in tremendous energy savings and extends the life cycle of the refrigeration equipment. The electricity savings average 10% – 12 % per year.
Internat Energy Solutions Canada verified the expected energy savings from the Town’s Mayfield Recreation Complex REALice installation. Through the monitoring and verification study (M&V), it was found that the REALice device saves 84,188 kWh of electricity and 2,800 m3 of natural gas annually at the facility. This results in approximately $10,775 annual utility cost savings and avoided greenhouse gas emissions of 6,972 kg of carbon dioxide. The REALice device has eliminated the need to use natural gas to treat the floodwater. Instead, incoming cold water treated by the REALice system is used to flood the ice.
