Upgrade in TIC but still within band...rates?

[PvNewbie]

Hi

I've got a customer on a 2kW TIC system but he wants to go to the maximum 4kW. Fair enough, but does anyone know/have any experience of what would happen to the FIT rate. Is it 43p for the 0-2kW part (installed Feb) and 21p for the 2-4kW part?

How would MCS registration work? Just modify the DNC declaration? It's an existing installation so presumably wouldn't require a new registration.

(Obviously DNO would be notified of change of inverter/plans to go over 16A etc)

Thanks

If the TIC is changed then the existing 2kW will stay at its present tariff (now 45.4p from April 1st assuming it was registered with the supplier before 3rd March) and the new part would get 21p if the house has an EPC of 'D' or better, otherwise just 9p. The total generation meter reading would be split 50/50 between the two in this case. The EPC would need to be submitted to the supplier.

You can modify the existing registration.

I was told otherwise, although I cant confirm one way or the other........... as it seemed abit of a grey area, as some installers were saying one thing, others another and some didnt have a clue........

However in the main what came across to us when we asked was this;

If you alter your array in any way, you could lose your original tariff altogther and then your whole array is transferred to the current tariff at time of application ???

In my opinion, Ted is right on this.
Why not install under G83, and keep it below 16amp, it would make your life a little easier.
I hope this helps

we've had chapter and verse on this from OFgem and ted's right, though we've been installing a second generation meter when we've done it to avoid complications / having to work on estimates of which system generated what.

Ted is right and we had this clarified by Ofgem after the guidance wasn't very clear

The situation on extensions to systems that are already accredited is pretty straight-forward. It is laid out clearly in the legislation which is covered by Part 4 of the original FiTs :

The Feed-in Tariffs (Specified Maximum Capacity and Functions) Order 2010

and as amended by this:

The Feed-in Tariffs (Specified Maximum Capacity and Functions) (Amendment No.3) Order 2011

The latest guidance to suppliers from OFGEM also clearly covers the points regarding extensions and EPCs:

I had not read the latter document before, but unless I am misunderstanding it they have an anomaly in the definitions in the glossary.
DNC and TIC are defined in the glossary and
DNC = TIC - power consumed by the installation.
But the definitions for Small scale low carbon generation and Eligible installation then say TIC cannot be greater than DNC......?

 

[Ian-LS]

yeah shouldn't be the DNC cannot be greater than the TIC?

 

[TedM]

which does not exceed the specified maximum Declared Net Capacity

is a reference to the 5MW limit for FiTs - which, bizarrely, is defined by DNC rather than TIC.

Ah yes, I understand now - I was trying to work out why the word 'maximum' was there.
