However from the 1st April, the system was changed to take account of the fact that certain technologies are more commercially viable than others, and so technologies that need more support for effective market deployment receive it.The new ‘banded’ system uses onshore wind power as a reference technology, so any technology which needs more support is granted additional ROCs and similarly more commercially viable technologies are granted less ROCs.The banding system is as follows:
