CALMAC Offering Free Commercial-Building Energy-Bill Analysis

The service allows organizations with more than 500,000 sq ft of air-conditioned space to upload a copy of an electricity bill through the CALMAC website for analysis by a rate specialist. The specialist reviews the bill to identify savings that can be achieved by shifting a building’s cooling load to nighttime off-peak hours, when energy is in low demand and nearly 50-percent cheaper than during peak daytime hours.

“A large majority of commercial-building owners and managers do not fully understand how demand affects the bottom line of their electricity bill, and they mistakenly assume that energy for commercial buildings is priced the same as it is in residential buildings,” Mark MacCracken, CALMAC chief executive officer, said. “Utility-billing formats can obscure the value of consuming nighttime electricity, but with our new service, we offer a clear view into true electricity pricing. We factor in demand tariffs and other charges that aren’t clearly labeled or fully explained in a statement and show how ice-based energy storage can benefit the bottom line.”

According to CALMAC, a common misconception is that if a building is not offered “time of use” pricing by the utility, then it is using a “flat rate,” the implication being there is no difference between daytime and nighttime costs. Once demand penalties are exposed, however, the difference in cost between nighttime and daytime energy use becomes apparent. CALMAC’s service is said to clearly show this difference.

CALMAC’s IceBank storage tanks take advantage of lower off-peak electricity rates by permanently shifting the energy required for cooling operations to off-peak hours. The tanks store energy in the form of ice at night, when demand is low. The next day, when energy rates are at their highest, the system melts the ice to cool occupants.
