The existing incentive mechanism, the Renewables Obligation (RO), is designed to support large scale renewable generation but was considered unsuitable for encouraging smaller scale projects.
FITs were introduced to focus specifically for small scale generation as fixed feed in tariff power purchase agreements provide the certainty of a viable and ascertainable revenue stream which enables small generators to obtain finance to build their projects Onshore wind developments with capacities of less than 5 megawatts are eligible under the scheme.
The FITs provide generators with two elements of payment: a generation tariff and an export tariff. The generation tariff is a fixed amount paid for every unit of electricity produced. In addition to this generators receive another payment for each unit of electricity which is exported to the grid rather than used on the premises. The export tariff is lower than the retail price of electricity so it makes sense to use the electricity onsite rather than to export it. In this way sites with larger electrical demand will benefit most.
