Smart grid projects are playing a key role in shedding light on how to move forward in this challenging transition. In 2011, therefore, the JRC launched the first comprehensive inventory of smart grid projects in Europe to collect lessons learned and assess current developments. The participation of project coordinators and the reception of the report by the smart grid community were extremely positive. It was therefore decided that the project inventory would be carried out on a regular basis so as to constantly update the picture of smart grid developments. This study is the 2013-2014 update of the inventory started out in 2011. The JRC?s 2013-14 Smart Grid database contains 459 smart grid R&D and D&D projects from all 28 European Union countries. Switzerland and Norway were studied together with the EU28 countries since they are present in a substantial number of projects with EU countries. Other 17 non EU countries are represented in the inventory by their participating organisations. The total investment of the smart grid projects amounts to ?3.15 billion.
