Senegal’s domestic gas reserves might be primarily used to produce electricity. Authorities expect that domestic fuel infrastructure projects will come on-line between 2025 and 2026, provided there is no delay. The monetization of those significant energy resources is on the foundation of the government’s new gas-to-power ambitions.
In this context, the global expertise group Wärtsilä conducted in-depth research that analyse the economic impact of the assorted gas-to-power strategies out there to Senegal. Two very different technologies are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle fuel turbines (CCGT) and Gas engines (ICE).
These research have revealed very important system price differences between the 2 major gas-to-power applied sciences the nation is currently contemplating. Contrary to prevailing beliefs, gas engines are in reality much better suited than mixed cycle gas generators to harness power from Senegal’s new gasoline resources cost-effectively, the examine reveals. Total value variations between the two applied sciences may attain as a lot as 480 million USD until 2035 relying on eventualities.
Two competing and really totally different applied sciences
The state-of-the-art vitality mix models developed by Wärtsilä, which builds customised vitality eventualities to determine the price optimum approach to ship new era capability for a specific country, exhibits that ICE and CCGT technologies present important price variations for the gas-to-power newbuild program running to 2035.
Although these two applied sciences are equally confirmed and dependable, they’re very totally different by means of the profiles by which they’ll operate. CCGT is a expertise that has been developed for the interconnected European electrical energy markets, the place it can function at 90% load factor always. On the opposite hand, versatile ICE know-how can operate efficiently in all working profiles, and seamlessly adapt itself to another era applied sciences that may make up the country’s vitality combine.
In เกจวัดแรงดัน reveals that when working in an electrical energy community of restricted dimension similar to Senegal’s 1GW nationwide grid, counting on CCGTs to considerably increase the network capacity would be extraordinarily pricey in all potential situations.
Cost differences between the applied sciences are defined by a variety of factors. First of all, scorching climates negatively influence the output of gasoline turbines more than it does that of fuel engines.
Secondly, because of Senegal’s anticipated access to low cost home gasoline, the working costs turn out to be much less impactful than the investment costs. In other words, as a end result of low gasoline prices decrease working costs, it is financially sound for the country to rely on ICE energy vegetation, that are cheaper to construct.
Technology modularity also performs a key function. Senegal is predicted to require an additional 60-80 MW of generation capability each year to be able to meet the growing demand. This is much lower than the capability of typical CCGTs crops which averages 300-400 MW that must be built in one go, resulting in unnecessary expenditure. Engine power crops, on the other hand, are modular, which implies they are often constructed exactly as and when the nation wants them, and additional extended when required.
The numbers at play are important. The mannequin exhibits that If Senegal chooses to favour CCGT crops on the expense of ICE-gas, it’ll result in as a lot as 240 million dollars of extra price for the system by 2035. The price distinction between the applied sciences may even improve to 350 million USD in favor of ICE expertise if Senegal additionally chooses to build new renewable energy capacity inside the next decade.
Risk-managing potential gasoline infrastructure delays
The development of gas infrastructure is a complex and lengthy endeavour. pressure gauge 10 bar delays usually are not unusual, causing fuel provide disruptions that may have a huge financial impression on the operation of CCGT crops.
Nigeria is aware of something about that. Only digital pressure gauge , important gasoline supply issues have triggered shutdowns at a few of the country’s largest fuel turbine power crops. Because Gas turbines function on a continuous combustion process, they require a relentless provide of gasoline and a secure dispatched load to generate consistent power output. If the provision is disrupted, shutdowns occur, placing an excellent pressure on the general system. ICE-Gas vegetation then again, are designed to regulate their operational profile over time and increase system flexibility. Because of their flexible working profile, they have been capable of maintain a a lot larger degree of availability
The study took a deep dive to analyse the monetary influence of two years delay in the gas infrastructure program. It demonstrates that if the nation decides to speculate into gas engines, the worth of gas delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further price.
Whichever means you have a look at it, new ICE-Gas generation capacity will decrease the total value of electricity in Senegal in all attainable scenarios. If Senegal is to meet electricity demand growth in a cost-optimal method, no less than 300 MW of new ICE-Gas capability might be required by 2026.
