- 1st major overhaul of an engine completed by Clarke Energy in Tunisia and starting a new cycle of 60,000 hours
- Slama Freres have made savings of more than 4 million Tunisian Dinars, after deduction of operating costs, and reduction of carbon emissions by more than 15 000 tonnes.
Slama Frères, part of the Slama Group is based in the in the governorate of Manouba. The group was the first industrial company in Tunisia to opt for a cogeneration energy solution using INNIO Jenbacher gas engines. Slama Frères’ cogeneration facility produces both electricity and heat, delivering overall energy efficiency to over 72%.
The installation, supplied and commissioned by Clarke Energy in March 2012, has achieved a return on investment well above expectations. The facility delivered in a payback period of 6 months less than originally planned in the feasibility study. For similar projects and with the current electricity and gas prices in Tunisia, the repayment period is now in the range of 27 to 30 months.
After 60,000 hours of operation, the cogeneration unit, equipped with the INNIO Jenbacher JMS416 engine, produced 67,800 MWh of electricity, covering more than 90% of the plant’s needs, 28,400 MWh of hot water at 75 ° C and 21,100 MWh of steam at 3 bar pressure. The operational availability over the entire first engine cycle has reached 96%.
In line with the instructions of the manufacturer INNIO Jenbacher, the Slama Frères engine received its new long block in 2020. Clarke Energy successfully completed this operation, a first in its kind in Tunisia, within the contractual deadlines and with 100% Tunisian service technicians.
With the new engine block in place, the Slama Frères facility began a second cycle of 60,000 hours, benefiting from the latest generation technology for the JMS416 engine.
