In May 2012, CTG bought 21.35% equity in Energias de Portugal (EDP), becoming its single largest shareholder. CTG and EDP have worked together to explore clean energy market in Europe using EDP’s global network, resources and managerial expertise to develop projects.
In 2015, CTG and EDP set up a joint venture Hydro Global to jointly develop middle and small hydro projects around the world. The Agreement on Cooperative Development of British Moray Offshore Wind Power Project was signed with EDP.
