The present analysis adds up to the discussion carried around the flexibilisation of the electricity networks, as means of higher diffusion of renewable energy sources (RES). Inspiring from innovation studies the paper proposes an economic rationale for considering RES technology manufacturers as investors in electricity networks.
Moreover,the present analysis scrutinize the extent to which the various economic operators within specific segments of the power supply chain invest in a portfolio of research and development activities,among which the electricity grids and storage technologies.
The intensity of these research investments was mapped across the European countries for the year of 2011.
The irgeo-graphic distribution confirms the rationale of an analysis based on canonical correlation testing the associations between RES market diffusion and power network indicators.
