This report establishes a list of indicators to assess the benefit of solar heat integration in industrial processes (SHIP). These indicators are Key Performance Indicators (KPI), they are linked to determined quantities calculated with relations approved by the consortium. Used in the frame of the present SHIP2FAIR project, these KPIs are generic and usable for future replication projects.
In the first part, the required inputs to calculate KPIs are identified and listed. These inputs are to be supplied by equipment providers, engineering and design offices, and end-users. These data characterize the state of reference of the process before SHIP integration and the new state after SHIP integration.
In the second part, KPIs are listed. To facilitate their understanding, they are split into five different categories related to technical, economic, environmental, social and regulation aspects. When necessary, a calculation method is proposed. As solar energy is not a constant resource, data collection is spread over time. To this effect, a reference period and a sampling rate are suggested. Depending on differences between different projects, some KPIs can be more relevant than others, a selection is to be done. At this step, it will be useful to define KPI’s target and then check the degree of matching between target and actual value.
When conversions are required for data reduction, in the absence of precise conversion factor, generic values are proposed to complete calculations.
To evaluate economic indicators, a table of different energies cost is proposed for European countries, with a focus on electricity and natural gas costs.
The set of KPIs selected during this analysis will enable the assessment of impacts related to the implementation of solar plants.
All the KPIs and their characteristics are to be validated by the consortium of SHIP2FAIR to have a common basis of evaluation for the project and for future SHIP replications (Replication Tool). Some of these KPIs will be selected and implemented in the future monitoring system and decision support system (DSS).
