Compared with 2020, the purchase costs and subcontracted work rose by €62 million to €623 million. The cost of grid losses was up €25 million, due to an increase in procurement tariffs for electricity. The cost of transport capacity rose by €14 million as a result of the higher tariffs set by TenneT. The cost of contractors and materials went up by €11 million, accounted for by the greater volume of work on the grid carried out in 2021.
