How much money of the Renewable Energy Certificates sale goes to the generators vs. how much money goes to the traders and marketers?
In general, certificates are bought in bulk and sold either wholesale or retail. This provides resellers with the margins needed to stay in business. Larger deals are generally done at a minimum of profit while smaller deals require larger margins, just like any other commodity. The profit depends on the operating model of the generator, wholesaler or retailer. Most of the money goes to the generator while the retailers or wholesalers mark up against what the markets will bear.
