Passage: The location chosen for this new building was plotted where the original Tejo Power Station still stood. Despite being made up of a combination of workshops and warehouses, before demolishing it, a new location had to be found to accommodate these roles that were complementary but indispensable to the plant's operation. Thus the decision was made to purchase the property and buildings where the old sugar refinery Senna Sugar Estates, Ltd. (owned by the "Companhia de Açúcar de Moçambique" - Mozambique Sugar Company¬) used to lie, located on the power station's east side.
