Senegal’s home gasoline reserves will be mainly used to supply electricity. Authorities expect that domestic fuel infrastructure projects will come online between 2025 and 2026, offered there isn’t a delay. The monetization of those significant energy resources is at the foundation of the government’s new gas-to-power ambitions.
In this context, the global expertise group Wärtsilä performed in-depth research that analyse the financial impression of the various gas-to-power methods available to Senegal. Two very totally different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gas generators (CCGT) and Gas engines (ICE).
These research have revealed very important system value variations between the 2 primary gas-to-power applied sciences the country is currently considering. Contrary to prevailing beliefs, fuel engines are actually a lot better suited than mixed cycle gasoline generators to harness power from Senegal’s new gasoline assets cost-effectively, the research reveals. Total cost variations between the two technologies could attain as a lot as 480 million USD until 2035 depending on scenarios.
เกจ์ออกซิเจนsumo competing and really different technologies
The state-of-the-art power mix models developed by Wärtsilä, which builds customised vitality eventualities to establish the cost optimal way to deliver new era capability for a selected nation, exhibits that ICE and CCGT applied sciences current vital cost variations for the gas-to-power newbuild program operating to 2035.
Although these two technologies are equally confirmed and reliable, they’re very different when it comes to the profiles during which they will operate. CCGT is a know-how that has been developed for the interconnected European electricity markets, the place it could possibly function at 90% load factor at all times. On the other hand, flexible ICE technology can operate effectively in all operating profiles, and seamlessly adapt itself to any other era applied sciences that may make up the country’s energy combine.
In particular our study reveals that when operating in an electricity community of restricted measurement corresponding to Senegal’s 1GW nationwide grid, counting on CCGTs to significantly increase the community capability can be extremely costly in all potential situations.
Cost variations between the applied sciences are defined by numerous elements. First of all, sizzling climates negatively impact the output of fuel generators greater than it does that of fuel engines.
Secondly, due to Senegal’s anticipated entry to cheap domestic gas, the working prices turn into less impactful than the funding prices. In other words, as a result of low fuel prices lower operating prices, it’s financially sound for the country to depend on ICE energy plants, which are cheaper to construct.
Technology modularity also plays a key role. Senegal is expected to require an extra 60-80 MW of technology capability each year to be able to meet the increasing demand. เกจวัดแรงดันน้ำ10บาร์ is far decrease than the capacity of typical CCGTs crops which averages 300-400 MW that have to be in-built one go, leading to unnecessary expenditure. Engine power plants, however, are modular, which implies they are often built precisely as and when the nation wants them, and further prolonged when required.
The numbers at play are important. The model reveals that If Senegal chooses to favour CCGT crops at 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 value difference between the technologies can even enhance to 350 million USD in favor of ICE know-how if Senegal additionally chooses to build new renewable vitality capacity within the subsequent decade.
Risk-managing potential gas infrastructure delays
The improvement of gas infrastructure is a fancy and lengthy endeavour. Program delays usually are not uncommon, inflicting fuel supply disruptions that can have an enormous monetary impression on the operation of CCGT crops.
Nigeria knows something about that. Only last yr, vital gas provide issues have caused shutdowns at some of the country’s largest fuel turbine energy vegetation. Because Gas generators function on a steady combustion course of, they require a constant supply of gas and a steady dispatched load to generate consistent energy output. If the provision is disrupted, shutdowns happen, placing a great strain on the general system. ICE-Gas crops however, are designed to adjust their operational profile over time and increase system flexibility. Because of their flexible working profile, they have been able to keep a a lot higher level of availability
The examine took a deep dive to analyse the financial impact of 2 years delay within the gas infrastructure program. It demonstrates that if the nation decides to speculate into fuel engines, the price of fuel delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in extra price.
Whichever method you have a glance at it, new ICE-Gas technology capacity will decrease the whole price of electrical energy in Senegal in all attainable scenarios. If Senegal is to fulfill electrical energy demand growth in a cost-optimal way, a minimal of 300 MW of new ICE-Gas capacity might be required by 2026.
