The purchase costs and costs of subcontracted work were up by €28 million compared with the preceding year and amounted to €452 million. The costs of contractors and materials were up by €20 million, accounted for by the greater volume of work on the grid carried out in 2019. The costs of grid losses were up €3 million, primarily because of higher purchase tariffs.
