GrantMcscott Posted November 26, 2018 Share Posted November 26, 2018 Hi I am building a house in Scotland and have had a quote from Scottish Power Networks for a connection to the grid. They have a list of about 50 to 60 alternative providers that can do the work so I would like to compare the quote. https://www.spenergynetworks.co.uk/userfiles/file/Active_ICPs.pdf Not sure who I should contact though for another couple of quotes Has any one had any experience with this thanks Link to comment Share on other sites More sharing options...
Simplysimon Posted November 26, 2018 Share Posted November 26, 2018 i had the same problem, a lot on the list will only do big jobs, some won't dig the road. i contacted a local goundworker who will dig the road and lay the trunking and spenergy will make the connection.

GrantMcscott Posted November 26, 2018 Author Share Posted November 26, 2018 Thanks the quote of SPNetworks is 12K that is with me doing the ground works. The reason is they need to install a transformer so was looking for comparison Link to comment Share on other sites More sharing options...
ProDave Posted November 26, 2018 Share Posted November 26, 2018 Are you on your own or near other houses? £12K even with a new transformer sounds very steep. A local near here paid £10K which included undergrounding about 200 metres of 11KV overhead line, provision of a new transformer and the supply. If there is an existing transformer can you avoid the need for upgrading it by accepting a lower KVA supply rating? I accepted their offer of a 12KVA supply as I am sure if I had asked for more there would have been a cost for upgrading the local transformer.

GrantMcscott Posted November 27, 2018 Author Share Posted November 27, 2018 I think I will go back to SPN and ask for a firm quote to see if this changes Link to comment Share on other sites More sharing options...
jamieled Posted November 27, 2018 Share Posted November 27, 2018 @GrantMcscott do you know where they're taking the supply from and what exactly the 12k covers (i.e. is from an 11kv/33kv line, wayleaves involved, road works etc?). It's not far off (slightly cheaper) than my SSE quote. Link to comment Share on other sites More sharing options...
GrantMcscott Posted November 27, 2018 Author Share Posted November 27, 2018 Hi there is no wayleaves involved the supply is coming from 11 Kv line as there is 3 marked up on their location map. It states o the drawing 3 x 50 ACSR 11kV Link to comment Share on other sites More sharing options...
PeterW Posted November 27, 2018 Share Posted November 27, 2018 How much from the pole to the house in distance ..?? If the whole of the transformer cost is being passed to you then you should be able to argue that either they give you the full capacity, or if it’s shared in the future that you get a rebate on the costs. For comparison, I paid £1,300 for a 4m connection from a main no more than 450mm down in an unmade road ... Link to comment Share on other sites More sharing options...
ProDave Posted November 27, 2018 Share Posted November 27, 2018 You are drip feeding us details. How many properties? Single or 3 phase supply requested? What rating (how many KVA) have you asked for or been offered? How far from the 3 phase overhead to your plot? Is that going to be overhead or underground? if so who is doing the digging? Is the 11KV overhead being altered in any way or just a transformer and your connection? It may well require an upgraded pole or twin poles for the transformer) 11Kv work will require a partial network shutdown, that is not done live.

GrantMcscott Posted November 27, 2018 Author Share Posted November 27, 2018 Hi Dave sorry to answer your questions How many properties? 1 Single or 3 phase supply requested? Single What rating (how many KVA) have you asked for or been offered? 20 KVA How far from the 3 phase overhead to your plot? I would say about 100 meters Is that going to be overhead or underground? if so who is doing the digging? Underground and I will do the civils Is the 11KV overhead being altered in any way or just a transformer and your connection? It may well require an upgraded pole or twin poles for the transformer) 11Kv work will require a partial network shutdown, that is not done live. they have not stated thanks Link to comment Share on other sites More sharing options...
recoveringbuilder Posted November 27, 2018 Share Posted November 27, 2018 I think it’s well documented how much SP energy quoted me-almost 25k! There was no capacity left in the existing transformer, they couldn’t even give me 12kva as was suggested on here, there are 5 plots next to me which they said if they eventually asked for a supply (within 5 years) I would get a partial refund. We went back and forth trying to find a solution, we got a quote from another contractor of £8k to do the digging but we still would have had another £10k to pay for the cable.Just when I was losing the will to live I had a eureka moment and threatened to serve them notice on the pole that was on my land, the outcome of which was they did everything for under £5k!

As I say a friend near here had a LOT more work done on the HV network for £10K When you get that post the cost breakdown on here. Link to comment Share on other sites More sharing options...
GrantMcscott Posted January 12, 2019 Author Share Posted January 12, 2019 Eventually got the detail from SPEN see attached and a firm price of 11K 613732381_Design_Drawing_Time1546961672958_electric.pdf Link to comment Share on other sites More sharing options...
scottishjohn Posted January 12, 2019 Share Posted January 12, 2019 slight derail what is minimum you would want if going for PV and maybe selling some back in future Link to comment Share on other sites More sharing options...

I suspect that it may not (yet), and so need to be grid tied. There are inverters that will happily work in island mode around for off-grid installations, but I'm not sure how these might be integrated into the Tesla systems.

Ed Davies Posted January 12, 2019 Share Posted January 12, 2019 https://www.tesla.com/en_GB/support/powerwall/faqs#off-grid “If you are in a remote area without access to grid power, Powerwall and solar can offer an off-grid solution. For our remote off-grid offering, please place a deposit here and someone will contact you to discuss further.” But a bit further down: “I have a wind turbine/hydro turbine. Can I charge Powerwall with it? Powerwall does not currently integrate with other renewable generation equipment. Please stay tuned for future updates.” Link to comment Share on other sites More sharing options...
