Indicators are as physical parameters that can be measured and available as the data to obtain in quantitative or qualitative form [46]. An indicator is something that provides evidence to a matter of larger significance or makes noticeable a trend or occurrence that is not immediately detectable [3] and should be Specific, Measurable, Achievable, Relevant and Time bound [47]. There are certain key parameters that need to be recognized and analyzed correctly to ensure sustainability assessment in energy planning and management systems. Indicators for sustainability assessment in energy planning and management can be identified through extensive literature review and expert inputs. Regarding the present research work, we have explored various available litera- ture, like national and international journals; the proceedings of national and international conferences; authentic websites of government and non government organizations; and energy reports published by various government/non government depart- ments and research organizations. Important twenty-five indica- tors for sustainability assessment in energy planning and management have been identified from extensive literature review and from expert inputs. Further, these indicators have been categorized into five key dimensions through expert judgments; other details regarding data collection are given in Section 5.1. However, the identified dimensions and indicators have been explained as follows:
