Spanish firm Nabrawind Technologies will install its first self-erecting Nabralift tower in Morocco, with the 144m-tall structure set to become the tallest wind tower in Africa.

Foundation works for the tower will begin this summer, and installation is due to complete by early-2020.

The tower has the capacity to produce 3.5MW of power, with its self-erecting system allowing the installation of wind turbine generators without the need for a large crane.

According to Nabrawind, the system helps elevate the generators in intermediate stages and install the tower's sections underneath.

The piled foundation of the Nabralift makes it 60% cheaper than traditional wind towers.

The gravitational foundation of a traditionally designed tower at 144m would require 500m3 of concrete and 54.4 tonnes (t) of steel, while Nabralift's needs only 80m3 of concrete and 9.1 t of steel.

Siemens Gamesa’s 115m-high tower in South Africa is the continent's tallest wind tower at present, and Nabrawind's wind tower in Eslava, Navarra, at 160m, is the world's third-tallest.
