Senegal faces key expertise decisions in its seek for the optimum gas-to-power technique

Senegal’s domestic gas reserves shall be mainly used to provide electrical energy. Authorities expect that home gas infrastructure projects will come online between 2025 and 2026, supplied there is no delay. The monetization of these vital energy assets is at the foundation of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä performed in-depth research that analyse the financial impression of the varied gas-to-power methods available to Senegal. Two very different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gasoline generators (CCGT) and Gas engines (ICE).
These research have revealed very important system value differences between the 2 main gas-to-power technologies the country is currently considering. Contrary to prevailing beliefs, fuel engines are in fact much better suited than mixed cycle fuel turbines to harness power from Senegal’s new gas sources cost-effectively, the research reveals. Total value variations between the 2 applied sciences could attain as much as 480 million USD until 2035 relying on scenarios.
Two competing and really totally different applied sciences
The state-of-the-art energy combine fashions developed by Wärtsilä, which builds customised power eventualities to determine the fee optimum approach to deliver new technology capacity for a selected nation, exhibits that ICE and CCGT technologies present significant price variations for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally confirmed and reliable, they’re very completely different when it comes to the profiles by which they’ll function. CCGT is a expertise that has been developed for the interconnected European electrical energy markets, the place it could possibly function at 90% load factor always. On the other hand, flexible ICE expertise can operate effectively in all working profiles, and seamlessly adapt itself to some other technology technologies that will make up the country’s power mix.
In เกจวัดแรงดันnuovafima reveals that when working in an electrical energy community of restricted size such as Senegal’s 1GW nationwide grid, relying on CCGTs to considerably broaden the community capacity can be extraordinarily pricey in all potential situations.
Cost differences between the technologies are explained by a variety of components. First of all, sizzling climates negatively impression the output of gas generators more than it does that of gasoline engines.
Secondly, because of Senegal’s anticipated entry to low cost domestic gas, the operating prices turn into much less impactful than the investment prices. In different words, as a end result of low fuel costs lower operating prices, it’s financially sound for the country to depend on ICE power crops, which are less expensive to build.
Technology modularity also plays a key position. Senegal is anticipated to require an additional 60-80 MW of technology capacity every year to find a way to meet the increasing demand. This is far decrease than the capability of typical CCGTs crops which averages 300-400 MW that should be inbuilt one go, leading to pointless expenditure. Engine energy plants, however, are modular, which suggests they can be constructed exactly as and when the nation needs them, and further extended when required.
The numbers at play are important. The model reveals that If Senegal chooses to favour CCGT plants at the expense of ICE-gas, it will lead to as a lot as 240 million dollars of extra price for the system by 2035. The cost difference between the technologies may even improve to 350 million USD in favor of ICE technology if Senegal also chooses to construct new renewable vitality capacity within the subsequent decade.
Risk-managing potential gas infrastructure delays
The improvement of fuel infrastructure is a posh and lengthy endeavour. Program delays are not unusual, inflicting gasoline supply disruptions that can have an enormous monetary influence on the operation of CCGT plants.
Nigeria knows one thing about that. Only final 12 months, vital gasoline supply issues have triggered shutdowns at a number of the country’s largest gasoline turbine energy vegetation. Because Gas turbines function on a continuous combustion course of, they require a constant provide of fuel and a secure dispatched load to generate consistent power output. If เกจวัดแก๊ส is disrupted, shutdowns happen, putting an excellent strain on the overall system. ICE-Gas plants on the other hand, are designed to adjust their operational profile over time and enhance system flexibility. Because of their versatile operating profile, they were in a position to preserve a a lot larger level of availability
The research took a deep dive to analyse the financial impact of two years delay within the gas infrastructure program. It demonstrates that if the nation decides to invest into fuel engines, the price of gasoline delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further cost.
Whichever method you have a look at it, new ICE-Gas technology capability will decrease the whole price of electricity in Senegal in all potential eventualities. If Senegal is to satisfy electrical energy demand progress in a cost-optimal method, a minimum of 300 MW of recent ICE-Gas capacity might be required by 2026.
