It's a shame folks in industry don't collaborate more, we've been there done that a few years ago here - albeit with wind.

The close down report is a good read.

@sean_ork

I think the difference here is that between WPD and SSE, SSE are not just a DNO they are also a generator and provider hence from your report

Scope and objectives

The scope of this project was the creation of commercial incentives to encourage an ESP to locate an ESS where it would provide real benefits to a DNO.
Objectives:
Create commercial contracts that will incentivise 3rd Party ESPs to locate on a constrained distribution network
Prepare a tender process that will ensure that the ESPs selected will fulfil the success criteria
Design up to 2 connection points for ESSs outside KPS
Award up to 2 ESPs

Success criteria
For this project to be a success commercial arrangements had to be identified that would be shown to attract ESPs with suitably tuned ESS

i.e SSE wanted to develop a contract to make money out of it.

The WPD approach is technically focussed, they are not a generator, they are not an energy provider. They are looking to understand the grid scale technical issues of energy storage and the economies of scale.

This is also one of the reasons why working with WPD makes them the easiest and most accommodating DNO in the country and time and time again come out as #1 for customer service

You might be right, just seems daft duplicating efforts - for what it's worth SSE have never given us any cause for concern.

I read " the creation of commercial incentives " more of a proof of concept point, being able to show that storage is financially viable is one of the sure fire ways of getting manufacturers really interested.

I followed what was going on up there when it was all being put together and I was impressed how the whole community got behind the project as well, great project and glad it's all working out for you guys.

Cheers, I'm sure Tesla would sell a good few of their batterys in a box device (if they dropped the price by two thirds) - there's a lot of electricity being generated and "managed" up here.

Re: battery Storage gest a £1m boost

for your scale and the industrial scale where space is not critical, there is far better, a whole lot cheaper, and orders of magnitude more environmentally friendly storage technologies (than Li-ion or Lead/acid or gel) already available.
.. Watch this space for announcements as they come to the domestic market (so long as you've got the space). If you haven't even a tesla powerwall weights about 100kg So you'll need a strong wall.

We know how to build strong here, it gets a bit breezy once in a while - which is rather handy, and makes me smile once a quarter.

#1 thing we picked up over the last couple of days (obvious when you think about it duh ! I just hadn't got that far with my thinking)

If a battery storage system is installed in parallel to an existing PV system EVEN IF the battery storage system is ony designed to supply power to reduce imprted power, so not set up to export, as it is a generator in it's own right it needs DNO approval to connect., AND if you're fitting it to an exisiting 4kWp/3.68kW / 16A system you'll need to submit a G59 application ......

If you are REPLACING the existing inverter or it's a NEW installation with a combined store / pv system then so along as <=3.68kW not an issue. Though if replacing, you should of course notify the DNO of a change of generator.

Really? Is that true?

 

[Worcester]

Really? Is that true?

Which bit ?

 

[SibertSolar]

All of it!

a) battery storage considered a generator?
B) retrofit that takes total "generation" capacity >16A = G59 application/pre-notification?

 

[TedM]

I think whether this applies or not will depend on the design of a specific system, and if it is based around an AC coupled or DC coupled battery.

I can see DNOs being sniffy about an AC coupled system (simply because of definitions even if in practice it shouldn't be a problem) but cannot see why they would have any issue with a DC coupled system that utilised a single G83 compliant inverter.

Obviously, retro-fitting a battery system is almost certainly going to be AC coupled.

eta - The battery won't be considered an SSEG, but the inverter via which the battery discharges will be.

 

[SibertSolar]

Exactly what I was thinking Ted - most retrofit systems will be AC coupled.....
