I just had a thorough look with @p-glaum at the length_factor. As far as we understand, in the clustered network, the length of all lines is set to the haversine distance between the buses multiplied by length_factor.

However, the capital costs in add_electricity consider the length factor a second time:

Thus we might be overestimating the capital_cost of lines, with the default setting by 25%. The same probably also applies to links.
