Utility Bill Tracking systems are at the center of an effective energy management program. However, some organizations spend time and money putting together a utility bill tracking system and never reap any value. This paper presents three utility bill analysis techniques which energy managers can use to arrive at sound energy management decisions and achieve cost savings.
Utility bill tracking is at the heart of an effective energy management program. Merely comparing utility bills can yield inaccurate indications of the amount of savings from energy management programs due to the unaccounted influence of weather or other factors. Correcting utility bills for weather data will give more accurate representations of savings that were accrued. This paper presents the how and why of weather correction for those who want to become more familiar with the concepts and methodology.
Today’s utility bill tracking software can deliver excellent results for energy managers who want to gain a comprehensive understanding of utility usage and costs in their facilities. All of the major commercially available utility bill tracking software programs are good at what they do, however, they are distinctly different in functionality and capacity.
Every year, the typical energy manager will generate, or receive from management, a fixed energy budget. Throughout the rest of the year, he will be held to this static standard. He may also be asked to save 5% from prior year’s energy usage, or may simply be provided with less money than the prior year. This method is simple for management to understand. Either the energy manager is meeting savings targets or he is not. Unfortunately, this method does not produce a realistic picture of how much energy the energy manager is saving.
