The GGCS is designed to be simple and low cost to operate. Fees are calculated so as to cover the running costs of the GGCS. As well as the administration costs of overseeing the Scheme and system maintenance, these running costs include the costs of auditing scheme participants. The scheme operator does not aim to produce a material surplus of income over running costs. The fees payable for taking part in it are broken down into the two categories outlined below.
The fees are set annually by the Oversight Panel which is run by Scheme participants and independent members and reflect the costs of running the Scheme. In reaching a decision, the Panel takes into account the volume of gas expected to flow and the running costs of the GGCS. A detailed budget will be prepared by the scheme administrator for this purpose. In the first year, the scheme administrator aims to recover in total an amount in the region of £5,000 through the fees.
Participants in the Scheme are required to pay an annual membership fee. The annual membership fee will be £500 per annum, and will be invoiced at the start of the calendar year or pro rata for those who join during the year. This fee will be set annually by the Oversight Panel which is run by Scheme participants and independent members and will reflect the costs of running the Scheme.
Participating gas suppliers are required to pay the scheme administrator a gas volume fee of 0.01p per kWh levied on its aggregate sales of green gas to end-use consumers in a given month. The system automatically reports on these purchases so that an invoice can be raised for each participating licensed gas supplier at the end of each month during which gas it has registered as having sold green gas to an end-use consumer. Suppliers will have 30 days to settle the invoice.
