Note 23 Purchase costs and costs of subcontracted work
Transport capacity and restrictions
Billing and payment collection
Contractors, materials and other
The purchase costs and costs of subcontracted work, at €402 million, were the same overall as in the preceding year. On the one hand, there was an increase in the costs of transport capacity and restrictions amounting to €13 million, due to higher charges and an increase in volumes, while, on the other hand, the costs incurred for network losses were down by €3 million, mainly owing to lower energy costs, and there was a reduction in the costs of hiring contractors and of subcontracted work of €12 million, largely as a result of the capacity challenges.
