Abstract: Salt Cross is a new garden village taking shape in West Oxfordshire, on land to the north of the A40 near the village of Eynsham. Salt Cross will be an exemplar for net zero carbon, energy positive development. To support this ambition and as part of the Local Energy Oxfordshire (LEO) project, Oxfordshire County Council has worked with Urbanomy (EDF Group) to develop a complete model of the new development and provide insight over the whole value chain of the energy and mobility concept. The future energy demand (buildings and EVs) and PV generation has been evaluated to quantify the net demand over various energy hub concepts. A focus has been made on predicting the peak demand and how to mitigate it through various flexibility types (thermal, battery, V2G), also providing new revenues along existing (arbitrage, frequency response) and future services (DSO). The results highlights the opportunities and challenges which will be addressed to reach the Net Zero ambition.
