The aggregator rate doesn't apply to stand-alone systems at all. So you could have 25 of them (or 1,025) and not be affected by the 20% reduction. It also doesn't apply to building connected systems over 250kW - but the rate there is just 8.9p in any case.

Sounds like both OFGEM and DECC have not understood what was proposed.

To get 15.2p the 'building' to which they are attached would have to be EPC 'D' too.

You need a nice warm site office, well, 25 nice warm site office's all with separate supplies and address's and then you may get your 15p rate.
Just a thought:wink_smile:

can you get portacabins with a D rating EPC?

 

[SolarCity]

You probably can, but if you can convince everyone that each portacabin has it's own address then you're doing very well indeed!

Its the 15.2 p with the export tarif ontop standalone arrays

 

[TedM]

Sedgy, you need to explain exactly what you mean by 'standalone'.

Do you mean a ground-mounted array, but where the power is connected back to the grid via one or more buildings?

Or do you mean a ground-mounted array where all power goes directly to the grid with no buildings involved? Your initial description made it sound like this.

If it is the first then there is a chance that you can get 15.2p (plus export) for a 50kW system on a single site where the building has an EPC of 'D' or better. And if you have fewer than 25 of these on different sites you will not be subject to the 20% aggregator deduction. If they are all on the same site then you have not got multiple 50kW systems, but a single larger one.

If it is the second option then you can only get 8.9p (plus export) no matter how many sites you have or what size they are.

IMO you need to be really careful with this, as Ofgem's advice almost always comes with a disclaimer attached, and they'll happily claim that you'd not supplied them with correct information etc and that it was your responsibility to ensure you complied with the legislation when the electricty company determines that they actually are stand alone systems.

A project of this size, you really want to either be getting specialist legal advice, or erring on the side of caution, otherwise you could find yourself liable for the difference between the 8.9p rate and the 15.2p rate if things don't pan out as you say they will.

btw, IME if you work on he basis that the OFgem team are utterly clueless, and will deny all knowledge of anything they've previously stated, and twist their previous words to suit their current purpose of saving DECC money, then you might stand a chance of not being led up the garden path by them.

 

[SolarCity]

I agree with Ted and Gavin. I just hope that it doesn't kill your project dead though as it's clearly a massive opportunity. Would 8.9p be workable?

just to clarify
standalone systems as everything generated goes back in to the grid no buildings involed for any epc ect

 

[Gavin A]

so it must get paid at the stand alone rate.

 

[Ian-LS]

Agree you cannot quote at 15.2p rate. It will only be eligible for 8.9p/kWh
