Data on a range of variables were captured. To allow comparability, flexibility (defined technically by VITO as a variable combination of time cost, energy availability and capacity) has been monetised as percentage of the total annual energy bill.
Hard numbers were also collected for variables such as the energy mix before and after the intervention (to establish how much renewable energy the intervention adds to the system), and economic data such as investment and running costs.
The RGU team also collected qualitative data. Partners were asked to score their business cases on how organisational, technical and legislative transferability and on other important business case factors such factors such as stakeholder interest and potential for local wealth creation.
