Senegal faces key know-how decisions in its seek for the optimum gas-to-power strategy

Senegal’s domestic fuel reserves shall be primarily used to provide electrical energy. Authorities expect that domestic fuel infrastructure projects will come online between 2025 and 2026, supplied there is no delay. The monetization of those important energy sources is on the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide expertise group Wärtsilä carried out in-depth studies that analyse the financial impression of the varied gas-to-power methods available to Senegal. Two very totally different applied sciences are competing to meet the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These research have revealed very important system value variations between the two primary gas-to-power applied sciences the country is currently contemplating. Contrary to prevailing beliefs, gasoline engines are in fact significantly better suited than combined cycle gasoline turbines to harness power from Senegal’s new gas resources cost-effectively, the study reveals. Total value differences between the two technologies might reach as a lot as 480 million USD until 2035 depending on eventualities.
Two competing and very completely different applied sciences

The state-of-the-art power mix fashions developed by Wärtsilä, which builds customised vitality eventualities to establish the fee optimum method to deliver new generation capability for a specific nation, shows that ICE and CCGT applied sciences present vital value variations for the gas-to-power newbuild program operating to 2035.
Although these two technologies are equally proven and reliable, they’re very different when it comes to the profiles during which they can function. CCGT is a technology that has been developed for the interconnected European electricity markets, the place it may possibly operate at 90% load issue always. On the other hand, flexible ICE expertise can function effectively in all working profiles, and seamlessly adapt itself to any other era applied sciences that can make up the country’s energy mix.
In explicit our study reveals that when operating in an electrical energy network of limited measurement corresponding to Senegal’s 1GW nationwide grid, relying on CCGTs to significantly increase the community capacity would be extremely pricey in all possible situations.
Cost differences between the applied sciences are defined by numerous components. First of all, hot climates negatively impact the output of fuel turbines greater than it does that of gasoline engines.
Secondly, because of Senegal’s anticipated entry to cheap domestic gasoline, the working prices turn out to be much less impactful than the investment prices. In different words, as a outcome of low gasoline costs lower operating prices, it is financially sound for the country to depend on ICE power crops, which are cheaper to build.
Technology modularity additionally performs a key position. Senegal is expected to require an additional 60-80 MW of technology capacity each year to have the ability to meet the increasing demand. pressure gauge วัด แรง ดัน is far lower than the capability of typical CCGTs crops which averages 300-400 MW that have to be built in one go, leading to unnecessary expenditure. Engine power vegetation, then again, are modular, which suggests they can be built precisely as and when the country wants them, and further extended when required.
The numbers at play are important. The model exhibits that If Senegal chooses to favour CCGT vegetation on the expense of ICE-gas, it will result in as a lot as 240 million dollars of extra cost for the system by 2035. The price distinction between the applied sciences can even increase to 350 million USD in favor of ICE technology if Senegal additionally chooses to construct new renewable power capacity throughout the next decade.
Risk-managing potential fuel infrastructure delays

The improvement of fuel infrastructure is a complex and prolonged endeavour. Program delays aren’t uncommon, inflicting gas supply disruptions that may have an enormous financial impression on the operation of CCGT crops.
Nigeria knows something about that. Only final yr, important fuel supply issues have brought on shutdowns at a few of the country’s largest fuel turbine energy vegetation. Because Gas turbines operate on a steady combustion course of, they require a relentless provide of fuel and a secure dispatched load to generate consistent energy output. If the provision is disrupted, shutdowns occur, putting a fantastic pressure on the general system. ICE-Gas vegetation however, are designed to regulate their operational profile over time and increase system flexibility. Because of their versatile working profile, they were capable of maintain a much larger level of availability

The examine took a deep dive to analyse the financial influence of 2 years delay in the gasoline infrastructure program. It demonstrates that if the country decides to invest into gasoline engines, the value of fuel delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further cost.
Whichever means you take a look at it, new ICE-Gas generation capability will minimize the total price of electrical energy in Senegal in all attainable situations. If Senegal is to satisfy electricity demand growth in a cost-optimal way, no much less than 300 MW of latest ICE-Gas capability might be required by 2026.
