STEG, short for Société Tunisienne de l'Élecriticité et du Gaz, has contracted Ansaldo Energia in 2018 to build the Mornaguia power plant. The order, worth some 250 million Euros, covers construction, commissioning, equipment supply, as well as maintenance work.
Situated southwest of Tunis, the Mornaguia power plant is driven by two AE94.3A model gas turbines, plus the relative generators and auxiliary systems. All equipment has been manufactured in Ansaldo’s production facilities in Genoa, Italy.
As a quick-start turbine, the AE94.3A can reach baseload condition in less than 25 minutes thanks to a fast load ramp, making it suitable for grid balancing. The turbine can run in both open and combined-cycle mode. The turbine’s hot fuel change-over function allows the turbine to run on a wide range of fuels, from natural gas to liquids.
Since 1999, Ansaldo has installed over 70 units of AE94.3A turbines at customer sites worldwide with a combined capacity of almost 20 GW.
The Italian manufacturer has developed several power projects in Tunisia such as the Sousse C and Sousse D plants in the Sidi Abdel-Hamid region, and the Rades B plant. It also coordinates service work on the Ghannouch plant.
