The Global Development Standard is our in-house Project Development System.  It draws on years of experience in developing wind and solar projects across the globe.  It encapsulates our uniqueness as a global developer. It means we develop all our projects to international best standards even when not required to by the authorities in a country.  So financiers and investors know when they see a Mainstream project, it has been developed meticulously to the highest global standards.
