Views on the structure of future rounds of UK support for renewable schemes are being sought by the government. Minister in charge of renewables, Charles Wardle, claims the Non-Fossil Fuel Obligation (NFFO) is a fundamentally sound mechanism for weaning the industry. In particular he believes the competitiveness encouraged by the NFFO mechanism has been instrumental in bringing down the price of renewables towards convergence with the market price for electricity. But he adds there is always scope for improvement. "We will be inviting views from trade associations and other collective bodies on the framework for NFFO 4."
