Integrid - Bridging the Gap

57 Shift to HLUC-perspective. In September 2019, the CBA approach was revised to reflect actual developments regarding the progress and focus of the Demos. The focus of the calculations was set on the cost and benefits for a subset of high- level Cases of Use (HLUCs) under each demo, based on the likely Demo progress within the project period and the data expected to be available. In addition, steps were taken to ensure that CBA results could be calculated for HLUCs in the event that real data were to be absent, by sourcing data through simulations, research and expert opinion where possible. Sensitivities. According to the JRC methodology, the goal of the sensitivity analysis is to find the range of variables leading to a positive outcome of the CBA. This requires identifying the break-even value of critical variables, i.e. the value that would lead to an NPV of zero, or more generally, for the outcome of the project to fall below the minimum level of acceptability. By assessing the sensitivities, DNV GL used the JRC methodology as a guideline. DNV GL’s main goal for the sensitivities was to provide useful insights that provide valuable additional information on the CBA results. From this perspective, DNV GL used two principles: 1. Calculate break-even value of critical variables on HLUCs that result in a positive NPV (in line with JRC-methodology). 2.Research parameters that influence the NPV outcome (e.g. linearly, exponentially, etc.), to sense check demo assumptions or where a sensitivity may provide a learning insight. Data sources. The purpose of this CBA is to assess whether the HLUCs as trialled by the InteGrid Demos are economically beneficial. For this reason, the primary source of cost and benefit data is information provided by the relevant InteGrid partners involved in each demo. On some occasions, where the Demos did not physically deploy a solution, data was obtained through simulations from InteGrid partners. Where neither real nor simulated data was available from InteGrid partners, the CBA sourced assumptions through expert opinions or estimates from partners, or through research of professional or academic sources.
