Cost attributes for electricity infrastructure

[ChaelKruip]

Currently, the user is responsible for coming up with costs figures for electricity infra. I think we should add some typical numbers to the documentation (and link to that in the interface) to help users pick realistic costs.

Based on very incomplete data from @JeroenvdLogt I have compiled a table for transformers:

Capacity [kW]	Investment [EUR]	Yearly O&M [EUR]	Lifetime [years]
50	2100	100	30
100	3000	100	30
160	3800	100	30
400	7000	100	30
1000	12000	100	30
300000	2000000	100	30
500000	4000000	100	30
750000	7500000	100	30

The table below contains even more preliminary data on cables:

Capacity [kVA]	Investment [EUR/km]	Yearly O&M [EUR]	Lifetime [years]
283	4588	?	50
326	5426	?	50
374	6258	?	50
442	6955	?	50
540	8700	?	50
645	9687	?	50
750	10921	?	50
803	11003	?	50
1066	15246	?	50

@MarjoleinSchwachofer @ThomBuijs if you also think this is useful could you please find a person to validate these numbers?

I think this is useful, I already wanted to discuss this in our team after their holidays.

I however do not know how long this will take. The infrastructure constitutes not only of the transformers , but also cables, secondary infrastructure etc. This will be more difficult. People would also need some guidelines on how to relate number of connections to the infrastructure (and this is different for different locations etc.)

I will discuss this in our team.

👍

but also cables

That's the second table. 😄

Curious what ideas you will come up with!
