ROC – These incentives are also know as renewables obligation certificates in the UK. They are handed out to clean energy providers for every megawatt hour(MW/hr) that a wind farm or tidal turbine might produce.
The interesting thing is that these certificates can then be traded, typically with polluting companies such as coal fired power stations. These companies have to buy ROC’s commensurate with the amount of carbon dioxide they emit. In the recent past, the ROC’s have been traded at roughly £47($77) each.
That’s a significant incentive especially if multiple ROC’s are offered for every MW/hour generated as the current forward price of electricity is around £40 for every MW/hr produced.
