Devices, systems and methods are provided for comparing energy-related data among a number of facilities or building associated with a single enterprise and reporting energy calculations to an enterprise manager. A method, according to one implementation, includes the step of receiving parameters related to the consumption of energy at a plurality of facilities of an enterprise. Based on the received parameters, the method further includes the step of calculating a grading index for each facility. The method also includes ranking the facilities based on the calculated grading indices and predicting a positive expected result in response to improving one or more lower-ranked facilities to match the grading index of a higher-ranked facility. The calculating the grading index may include calculating an energy efficiency value for each facility and/or calculating a risk factor for each facility, the risk factor related to power quality issues.
