Senegal faces key know-how choices in its search for the optimum gas-to-power technique

spmk700 ’s home gasoline reserves shall be mainly used to produce electricity. Authorities anticipate that domestic gas infrastructure initiatives will come on-line between 2025 and 2026, supplied there is not a delay. The monetization of these important energy sources is on the basis of the government’s new gas-to-power ambitions.
In this context, the global know-how group Wärtsilä performed in-depth studies that analyse the financial impression of the varied gas-to-power methods out there to Senegal. Two very different applied sciences are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gas generators (CCGT) and Gas engines (ICE).
These studies have revealed very significant system price variations between the two major gas-to-power applied sciences the country is presently contemplating. Contrary to prevailing beliefs, gas engines are in fact much better suited than combined cycle gas generators to harness energy from Senegal’s new fuel sources cost-effectively, the study reveals. Total cost variations between the two technologies might reach as a lot as 480 million USD until 2035 relying on scenarios.
Two competing and very totally different applied sciences
The state-of-the-art power combine fashions developed by Wärtsilä, which builds customised power eventualities to determine the price optimum approach to ship new era capacity for a particular nation, reveals that ICE and CCGT applied sciences current important cost differences for the gas-to-power newbuild program operating to 2035.
Although these two applied sciences are equally confirmed and reliable, they are very totally different by way of the profiles by which they’ll operate. CCGT is a technology that has been developed for the interconnected European electrical energy markets, where it could perform at 90% load factor at all times. On the opposite hand, versatile ICE technology can operate effectively in all working profiles, and seamlessly adapt itself to some other technology technologies that will make up the country’s power combine.
In explicit our examine reveals that when operating in an electrical energy network of restricted dimension similar to Senegal’s 1GW nationwide grid, counting on CCGTs to significantly increase the community capacity would be extraordinarily pricey in all possible eventualities.
Cost differences between the applied sciences are explained by a variety of factors. First of all, hot climates negatively impression the output of gasoline turbines greater than it does that of fuel engines.
Secondly, because of Senegal’s anticipated entry to cheap home gas, the operating costs become much less impactful than the funding prices. In other phrases, as a outcome of low fuel costs decrease working costs, it is financially sound for the nation to rely on ICE power plants, which are inexpensive to build.
Technology modularity additionally performs a key role. Senegal is anticipated to require an additional 60-80 MW of era capacity every year to have the flexibility to meet the increasing demand. เกจวัดแรงดันดิจิตอลราคา is far lower than the capacity of typical CCGTs crops which averages 300-400 MW that have to be inbuilt one go, leading to pointless expenditure. Engine energy vegetation, on the other hand, are modular, which implies they can be constructed exactly as and when the country wants them, and additional extended when required.
The numbers at play are vital. The mannequin shows that If Senegal chooses to favour CCGT vegetation on the expense of ICE-gas, it’ll result in as much as 240 million dollars of extra cost for the system by 2035. The price difference between the technologies can even increase to 350 million USD in favor of ICE technology if Senegal additionally chooses to build new renewable power capacity inside the subsequent decade.
Risk-managing potential gas infrastructure delays
The development of gasoline infrastructure is a complex and lengthy endeavour. Program delays are not uncommon, causing gas supply disruptions that can have an enormous financial impact on the operation of CCGT vegetation.
Nigeria is aware of one thing about that. Only last year, important gasoline supply points have triggered shutdowns at a number of the country’s largest fuel turbine power vegetation. Because Gas turbines function on a steady combustion process, they require a relentless provide of gasoline and a secure dispatched load to generate constant energy output. If the supply is disrupted, shutdowns happen, placing an excellent strain on the general system. ICE-Gas plants then again, are designed to regulate their operational profile over time and enhance system flexibility. Because of their versatile working profile, they had been capable of maintain a much greater stage of availability
The examine took a deep dive to analyse the monetary influence of two years delay within the fuel infrastructure program. It demonstrates that if the country decides to speculate into fuel engines, the cost of gasoline delay would be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in additional cost.
Whichever way you look at it, new ICE-Gas era capacity will minimize the entire cost of electricity in Senegal in all potential scenarios. If Senegal is to fulfill electricity demand development in a cost-optimal way, a minimal of 300 MW of latest ICE-Gas capacity shall be required by 2026.
