Ofgem introduced rules in 2014 to increase liquidity in the wholesale markets and improve access to forward markets for small suppliers.
The "Liquidity in the Wholesale Electricity Market" special licence condition applies to RWE Generation UK as well as several other large generators in the GB market. It came into force on 31 March 2014.
Part of this new special licence condition is the "Request for Trading Agreement", which sets out the process for the negotiation of trading agreements with Eligible Suppliers (known as a Grid Trade Master Agreement, or GTMA). More information, including a list of Eligible Suppliers, is available on the Ofgem website:
