The European wine sector is one of the most affected by the threat of climate change, but it also presents great potential for big improvements in sustainability. However, mitigation measures are being adopted way too slowly. The Life CLIMAWIN project addresses the problem of climate change by involving the wine sector in its mitigation. This is done by means of converting the wineries and vineyards into a compendium of climate change mitigation actions. One of these actions is the smart management of the energy flows. Energy is one of the key emission sources in both vineyard and winery processes. To address this, a very significant case study located in the Ribera del Duero wine region (Spain) has been chosen as a demonstration hub. To avoid the impacts of building a power line in the natural site, a smart stand-alone microgrid based on renewable generation has been incorporated. The microgrid integrates all energy sources and loads in the vineyard-winery facilities as a whole: vineyard, winery, farming and enotourism facilities. The main objective is to achieve a remarkable reduction of emissions from the activities. To do so, a smart control system is being designed, implemented and validated. This control system will allow the energy management of the microgrid in order to cover the energy demands from the most efficient, sustainable and economic possible way, maximizing the renewable fraction and therefore reducing emissions from fossil fuel generator use.
