If I register for ROCs, can I receive the feed-in tariff?

You cannot claim both Feed-In Tariffs and ROCs.

However if you have a ystem installed before 15th July 2009 you need to have been regesitered for ROCs and then transfer to the Tariffs on 1st April 2010. See here for more details.

Can renewable systems claim both the Feed-in Tariffs and the Renewables Obligation?

No. Systems are only eligible for one of the schemes. Small systems will have to use the Feed-In Tariffs and large systems, above 5 megawatts, can only use the RO. Systems between 50kW and 5MW get a one-off choice of FITs or RO, but won’t be able to claim both or to chop and change.

Can builders claim FITs on installations under the Code for Sustainable Homes?

Yes they can. The government has accepted that this would be a good way of helping builders cover any additional costs in achieving Zero Carbon Buildings.

Can the Tariffs be applied for if the company is taking part in the Carbon Reduction Commitment?

The government intends to treat energy which earns tariffs the same way as ROC-earning generation (i.e. it would not qualify as zero emissions but would have to be assigned emissions at the grid average).

The only way of getting full renewable credit under the CRC, therefore, is not to register for Feed-In Tariffs, the Renewable Heat Incentive or the Renewables Obligation.

We think this is inappropriate and are making representations accordingly.

Can systems already registered for ROCs stay in the RO?

Only if they are above 50kW. Smaller systems will generally have to transfer to the fits as shown here.

Which is better financially for larger systems, FITs or ROCs?

The government has tried to set the tariffs for larger systems at about the same level as the RO.

The decision on which to go for will depend on your view of the administration associated with each option, and the certainty of the price you will get under each (ROC and electricity prices are both variable and can be volatile at times).

What is the RO banding review?

The Renewables Obligation (RO) supports renewable generation above 5MW (and some projects between 50kW and 5MW). It provides an incentive not in the form of a fixed tariff, like the FITs, but by awarding green certificates called Renewable Obligations Certificates or ‘ROCs’.

When the RO was first introduced, all technologies received one ROC for every MWh of electricity delivered. The RO has subsequently been ‘banded’ with some renewable technologies, such as solar PV receiving 2 ROCs per MWh. Some (like offshore wind) get 1.5 ROCs; others still get 1 ROC; while others get less than 1 ROC.

The banding review is reassessing how many ROCs should be awarded to each technology band under the RO.

Are the tariff levels published following the Review now set in stone?

Not necessarily! From April 2013 some tariffs (for larger systems up to 5MW) may be adjusted further depending on the equivalent RO banding. The Phase 2B Review decision said:

Generation tariffs for the largest capacity band for each technology will continue to be consistent with support under the Renewables Obligation, and will be adjusted in line with current support levels and the outcome of the RO Banding Review.

Which tariff bands will be linked to pricing under the RO?

Those tariffs for sizes up to 5MW for most RO-eligible technologies.

This approach applies to the hydro band 2-5MW and the wind band 1.5-5MW.

However, the same does not seem to apply for PV, where the government said on their decision document following the Phase 2A review:

Although the majority of respondents to the consultation indicated a preference for the approach to degression to change once tariffs reach the financial equivalent of two Renewable Obligation Certificates [the support for solar PV under the RO], our updated analysis of PV installation costs suggests that a rate of return of nearly 8% can be achieved for large scale PV installations for a tariff considerably lower than 2 ROCs.
We have therefore decided that the degression mechanism should continue to operate when tariffs reach the equivalent of 2 ROCs, to minimise the risk of investor overcompensation and to limit the total cost of FITs support.

How are tariffs linked to pricing under the RO?

You want the simple answer? Tough!

All we can do is refer you to the wording in the Phase 2B Review decision

we will adjust generation tariffs for these bands to levels we consider to be equivalent to the support currently available under the RO. These are calculated using a value of £44.78 per ROC, which is 1.1 times the 2012/13 buyout price. Generation tariffs from 1 April 2013 until 31 March 2017 will be set at a level equivalent to the levels of support provided under the RO to a 5MW plant as a result of the RO Banding Review. Tariffs for 2017/8 and beyond are set at the level of 2016/17. However we expect that tariffs will be reviewed before this time, particularly given the wider context of Electricity Market Reform, so this should be taken as an indicative position in the interim.
