Provided herein are systems, methods, and software for calculating energy effectiveness in an industrial automation system. In one implementation, a computing system is directed to at least acquire production energy information indicating the amount of energy used by a machine during a processing period to process one or more parts and acquire process energy information indicating the sum of energy used by the machine during the processing period to process the one or more parts and to not process any parts. The computing system also acquires a total number of parts expected to be processed during the processing period and a total number of good parts processed during the processing period. An overall equipment energy effectiveness is calculated based on a ratio of the production energy information to the process energy information and based on a ratio of the total number of good parts to the total number of parts.
