In Belgium are two supporting instruments. The major one is quota system which based on quota obligation, tradable certificates and minimum and maximum prices. Income tax reduction as a fiscal regulation mechanism, is additional instrument which supports geothermal and solar technologies. [54] In the quota system, energy suppliers present that consumers from certain region (in Belgium are three regions: Wallonia, Flanders, Brussels City) are supplied by the green energy and then the regional regulatory authority allocates green certificates. One certificate is gained per 1 MWh of the green energy which was supplied to consumers. To be supported by that instrument the operator system has to be authorized (if obtains certificates of origin). Moreover in case of wind, tidal and wave technologies the special license from responsible ministry is required. Offshore power plant are eligible to receive support only for federal schemes. Special requirements are also for biomass power plants which combust wastes. Total energy content have to equals 35% or more. Hydro systems are supported only if their capacity equals or exceed 10MW of capacity. Support is eligible only for national projects and is statutory basis. In each region the quota is different. Following figure shows the quotas in Flanders (Fig. 55). [54]
Moreover there are also minimum payment for several technologies: [54]
