This report is intended to collect, present, and evaluate the various solutions applied in individual operational pilots for their (upscaling and transnational transfer) potential, in terms of opportunities and barriers, over the short and long(er)-term. This is done by identifying the main characteristics of the solutions and sites and the relevant influencing factors at different local (dimension) contexts.\ud The analysis provides insights in barriers but also opportunities and conditions for success across four main dimensions that make up the local context landscape. We consider two main roll-out scenarios:\ud 1. Upscaling within the boundaries of the country where the operational pilot (OP) took place\ud 2. Transnational Transfer relates to the potential for transferring a (V4)ES solution to any of the other three (project) countries \ud There are several aspects within the four main dimensions that are cross-cutting for all four countries, either because EU legislation lies at its roots, or because market conditions are fairly similar for certain influencing factors in those dimension.\ud Ultimately, both Smart Charging and V2X market are still in their relevant infancies. The solutions applied in various SEEV4-City pilots are relatively straightforward and simple in ‘smartness’. This helps the potential for adoption but may not always be the optimal solution yet. The Peak shaving or load/demand shifting solutions are viable options to reduce costs for different stakeholders in the (electricity) supply chain. The market is likely to mature and become much smarter in coming 5 – 10 years. This also includes the evolvement (or spin-offs) of the solutions applied in SEEV4-_City as well. At least in the coming (approximately) 5 years Smart Charging appears to have the better financial business case and potential for large scale roll-out with less (impactful) bottlenecks, but looking at longer term V2X holds its potential to play a significant role in the energy transition. A common denominator as primary barriers relates to existing regulation, standards readiness and limited market availability of either hardware or service offerings.\ud SEEV4-City has published a significant collection of varying reports, many taking a specific focus. For more detailed information on, for example a particular solution at one of the OPs or more in-depth policy evaluation, please look into these additional reports. They can be found through the Interreg NSR or project specific website, or one of the partners of the project would be glad to provide them.

This OP was deployed in two phases, focusing on Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G). Its first phase took place at a private residence in Loughborough and ran from March 2017 up to December 2017. This phase 1 is also referred to as the ‘Loughborough pilot’. The second phase took place from February 2020 until present at a comparable residence in Burton-upon-Trent, thereafter, referred to as the ‘Burton pilot’ or ‘phase 2’. Both pilots included bi-directional chargers, Electric Vehicles (EV), Battery Static Storage (BSS) and rooftop solar PhotoVoltaic panels (PV). The main goals of this pilot were to demonstrate the added value of V2H and V2G of using additional energy storage and PV in households. Challenges encountered in the project include interoperability issues, particularly in phase 1, and the unforeseen development of the homeowner selling his house, meaning a new location needed to be found. However, this challenge ultimately provided an excellent opportunity to implement lessons for interoperability and to act upon the recommendations from the intermediate analysis of the Loughborough pilot. This report is mainly focussed on phase 1 (Loughborough), and additional analysis for Burton-upon-Trent (phase 2) can be found in the appendix.

This report provides evaluation of the SEEV4-City Operational Pilot at Leicester City Hall, in the city of Leicester, U.K. In cooperation with Cenex UK, a demonstration project was set up to evaluate the technical requirements and commercial benefits of V2B (Vehicle to Building) technology at Leicester City Hall, U.K. It is part of a collection of reports published by the project covering a variation of specific and cross-cutting analysis and evaluation perspectives and spans 6 operational pilots. This report is dedicated to the analysis of the pilot itself.

SEEV4-City is an innovation project funded by the EU Interreg North Sea Region Programme. Its main objective is to demonstrate smart electric mobility and renewable energy solutions integration and share its learnings. The project must report on the results of 6 Operational Pilots (OPs) of the following three Key Performance Indicators (KPIs): A. Estimated CO2 reduction B. Estimated increase in energy autonomy C. Estimated Saving from Grid Investment Deferral The project aimed to establish a common methodology to calculate the contributions to the three main KPIs with significant level of detail and accuracy (where feasible). This was a collaborative exercise between Work package (WP) partners leading WP3-Intelligence (Data analysis, monitoring and simulation), WP4- Operational Pilots Implementation and Coordination and WP5-Policy and Business Case work packages and was done in consultation with the OP partners. The result of this effort is collated in this defined approach the KPI Methodology report. It is part of a collection of reports published by the project covering a variation of specific and cross-cutting analysis as well as different evaluation perspectives spanning the 6 operational pilots.

The methodology should be a uniform approach that also is flexible enough to accommodate all combinations that make up the different solutions in 6 OPs. For KPIs A and B this required the use of sub-KPIs to differentiate the effects of each (individual and combination of) implemented solutions and prevent double counting of results. This approach also helped to ensure that all 6 OPs use a common way and scope to calculate the various results. Consequently, this allowed the project to capture the results per OP and the total project in one ‘measurement results’ template. The template is used in both the individual OP reports and the ‘KPI Results: Baseline & Final results’ report where all results are accumulated; each instance providing a clear overview of what is achieved. This report outlines the details of the methodology used and applied. It is not just meant to provide a clarification of the results of the project, but is also meant to allow others who are embarking on adopting similar solutions for the purpose of CO2 reduction, becoming more energy autonomous or avoid grid stress or investments to learn about and possibly use the same methodology.
