Senegal’s domestic fuel reserves shall be mainly used to provide electricity. Authorities count on that domestic gasoline infrastructure projects will come on-line between 2025 and 2026, supplied there isn’t a delay. The monetization of those vital energy assets is on the basis of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä carried out in-depth research that analyse the financial impression of the assorted gas-to-power strategies available to Senegal. Two very totally different technologies are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These studies have revealed very important system value variations between the 2 major gas-to-power applied sciences the nation is at present contemplating. Contrary to prevailing beliefs, gas engines are in fact a lot better suited than mixed cycle gas generators to harness energy from Senegal’s new fuel resources cost-effectively, the examine reveals. Total price differences between the two technologies might reach as a lot as 480 million USD till 2035 relying on eventualities.
Two competing and very different technologies
The state-of-the-art power mix models developed by Wärtsilä, which builds customised power situations to establish the cost optimal approach to deliver new technology capability for a selected nation, reveals that ICE and CCGT applied sciences present important cost variations for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally proven and dependable, they’re very different in terms of the profiles in which they’ll function. CCGT is a technology that has been developed for the interconnected European electricity markets, where it could operate at 90% load factor at all times. On the other hand, versatile ICE know-how can operate efficiently in all operating profiles, and seamlessly adapt itself to some other technology technologies that will make up the country’s vitality combine.
In explicit our study reveals that when working in an electricity network of limited size such as Senegal’s 1GW nationwide grid, relying on CCGTs to considerably expand the community capability can be extraordinarily costly in all possible situations.
Cost differences between the technologies are defined by a variety of elements. First of all, sizzling climates negatively influence the output of gas turbines greater than it does that of gas engines.
Secondly, due to Senegal’s anticipated access to cheap domestic fuel, the working prices turn into much less impactful than the funding prices. In different phrases, because low gasoline costs decrease operating prices, it is financially sound for the nation to depend on ICE energy plants, which are cheaper to construct.
Technology modularity also plays a key position. Senegal is predicted to require an extra 60-80 MW of generation capacity each year to be able to meet the rising demand. This is much lower than the capability of typical CCGTs plants which averages 300-400 MW that should be built in one go, leading to unnecessary expenditure. Engine power vegetation, on the other hand, are modular, which implies they can be constructed precisely as and when the nation needs them, and further prolonged when required.
pressure gauge ราคา ถูก at play are vital. The model reveals that If Senegal chooses to favour CCGT crops on the expense of ICE-gas, it’ll result in as much as 240 million dollars of additional value for the system by 2035. The value difference between the applied sciences can even improve to 350 million USD in favor of ICE know-how if Senegal additionally chooses to build new renewable power capacity within the next decade.
Risk-managing potential fuel infrastructure delays
The development of gas infrastructure is a fancy and prolonged endeavour. Program delays are not uncommon, causing gasoline provide disruptions that may have an enormous financial impact on the operation of CCGT plants.
Nigeria is aware of one thing about that. Only ตัววัดแรงดัน , significant gasoline provide issues have triggered shutdowns at a variety of the country’s largest gas turbine energy crops. Because Gas turbines function on a continuous combustion process, they require a constant provide of gas and a steady dispatched load to generate constant energy output. If the availability is disrupted, shutdowns occur, putting an excellent pressure on the general system. ICE-Gas plants then again, are designed to regulate their operational profile over time and increase system flexibility. Because of their flexible working profile, they were able to maintain a much greater level of availability
The examine took a deep dive to analyse the monetary impact of two years delay in the gas infrastructure program. It demonstrates that if the nation decides to speculate into gasoline engines, the worth of fuel delay can be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in further price.
Whichever way you look at it, new ICE-Gas generation capability will decrease the entire price of electricity in Senegal in all potential scenarios. If Senegal is to satisfy electricity demand progress in a cost-optimal way, at least 300 MW of new ICE-Gas capability shall be required by 2026.
