The variation experienced by the dismantling or restoration provisions during the year ended December 31, 2019, is mainly due to the increase in disbursements expected from the early closure of the Tarapacá and Bocamina I plants, which is part of the Group's agreement with the Ministry of Energy for the progressive closure of coal-fired power plants (see Note 18.e.x); and to a lesser extent due to an increase in the present value of the provisions, for a low discount rates applied.
