Probably also worth pointing out that in addition to ROCs there are REGOs, Renewable Energy Guarantees of Origin, or greenwash certificates(UK REGOs are also reported at OFGEM. These used to sell for just a few pence per MWh in the days when they could be bought in from solar schemes in India or Norwegian hydro, to allow retailers to make false claims about supplying you with 100% green energy. As the acceptable sources for REGOs have been tightened up, their prices have firmed. Again, the market is not transparent but I did see reports of prices of up to 10/MWh at one point. More recently, prices have dropped back (at least in Europe), but they are still useful bunce. The most recent values I can find are around €1.70/1.80/MWh.
Some retailers have given up making the greenwash claim to reduce their costs. Perhaps it will disappear altogether as more people come to realise the true costs of renewables.
