Over the past two months, more than 70 substations at various levels have been destroyed or damaged in Ukraine, and the damage, according to initial estimates, is already more than a billion dollars.
The simplest 110 kW substation costs $3 million, and the most complex costs $25 million.
A 330 kW substation costs a minimum of $15 million in the simplest version, and a large central energy facility costs more than $100 million.
Restoration usually costs about 10% of its cost if the damage is minimal, and if severe it can reach more than 85% of the construction cost.
