The Department of Energy and Climate Change's new feed-in tariff regime came into effect last Friday, but exactly how it will function has yet to be decided.

How Ofgem is to implement the new capping and queuing system, and how frequently the regulator will update the industry as to how much of each quarterly cap has been taken has yet to be confirmed, and there remain concerns over whether or not Ofgem will have the resource to manage it after the duties were unceremoniously dumped on its plate at the eleventh hour.
