On 22 April, the European Commission’s Joint Research Centre (JRC) published an update of its 2011 report "Smart Grid projects in Europe: lessons learned and current developments", the most comprehensive inventory of smart grid and smart metering initiatives across the EU, Croatia, Switzerland and Norway. The new release includes 281 smart grid projects and around 90 smart metering pilots and roll-outs, accounting for a total investment of € 1.8 billion. Large-scale projects with budgets of over € 20 million have increased their share from 27% in 2006 to 61% in 2012.
