Through a rough back-of-the envelope calculation we estimated to the total capital value of the EU electricity system, including generation, transmission & distribution and end-use.
The EU-28 has roughly 1000 GW installed capacity (end of 2014) [[i], figure 4]
The average investment cost for generation capacity can be calculated from the following addition: 20% natural gas at 750€/kW; 15% hard coal at 1550 €/kW; 15% nuclear at 4200 €/kW; 15% off-shore wind at 1300 €/kW, 15% hydro at 2100 €/kW, 5% lignite at 1250 €/kW, 5% PV at 1250 €/kW, 5% biomass at 2500 €/kW, and 5% oil at 2100 €/kW. [i, figure 4 and Table 1]
The total cost = 2100 B€
Installations in buildings
So in total there are around 300 million buildings, with each an electrical installation.
A very rough estimation of 300 million installations at 4000 €/installation = 1200 B€
Transmission and distribution networks
The cost of the US transmission and distribution grid was estimated at 2100 B$. [[iv]]
There are 508 million inhabitants in the EU28 compared to 326 million in the US
2100 B$ x 508/326 inhabitants x 0.88 €/$ = 2900 B€
The manufacturing of ICT appliances in the EU28 amounts to 0.0032% of the GDP, or 50 B€. [[v]]
Suppose a 10 year life-cycle for ICT appliances.
7.5/5.4 trade balance x 10 year life cycle = 700 B€
The manufacturing of household appliances in the EU28 amounted to 53 B€ in 2016 [[viii], page 6]
Suppose a similar trade balance as for ICT appliances (7.5/5.4).
And a similar product life-cycle of 10 years.
53 B€ x 7.5/5.4 x 10 year life cycle = 700 B€
Railways and trams
The EU railway sector invested 40 B€ in 2011 [[ix], page 22]. Some of it is in Diesel trains, but on the other hand the trams and trolley busses are not included. Suppose a product life cycle of 25 years.
40 B$/year investments x 25 year life cycle = 1000 B€
Industrial end-use devices
A rough estimation is that industrial electrical end-use systems are worth the double from ICT and household appliances. That would be 1400 B€
Adding the figures above leads to 10,000 B€
