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

Senegal’s domestic gasoline reserves shall be primarily used to provide electrical energy. Authorities anticipate that domestic fuel infrastructure tasks will come online between 2025 and 2026, supplied there isn’t any delay. The monetization of those vital power sources is at the foundation 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 impact of the various gas-to-power methods available to Senegal. Two very different technologies are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle gasoline generators (CCGT) and Gas engines (ICE).
These studies have revealed very significant system cost differences between the two primary gas-to-power technologies the country is presently considering. Contrary to prevailing beliefs, fuel engines are in fact much better suited than combined cycle fuel generators to harness energy from Senegal’s new gasoline resources cost-effectively, the study reveals. Total cost differences between the 2 applied sciences could attain as much as 480 million USD till 2035 relying on eventualities.
Two competing and very different technologies

The state-of-the-art vitality mix models developed by Wärtsilä, which builds customised power scenarios to determine the cost optimum way to ship new technology capability for a particular nation, shows that ICE and CCGT applied sciences present important value variations for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally proven and dependable, they’re very totally 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, where it could possibly function at 90% load factor at all times. On the other hand, flexible ICE expertise can operate effectively in all operating profiles, and seamlessly adapt itself to any other era applied sciences that will make up the country’s energy mix.
In specific our examine reveals that when working in an electrical energy network of restricted measurement similar to Senegal’s 1GW nationwide grid, counting on CCGTs to considerably broaden the network capability would be extraordinarily pricey in all possible eventualities.
Cost differences between the applied sciences are explained by a selection of components. First of all, scorching climates negatively influence the output of gasoline turbines greater than it does that of fuel engines.
Secondly, due to Senegal’s anticipated entry to low cost domestic gasoline, the operating costs become much less impactful than the funding prices. In different words, as a outcome of low gas costs decrease working prices, it is financially sound for the country to depend on ICE energy vegetation, which are inexpensive to construct.
Technology modularity also performs a key function. Senegal is predicted to require an extra 60-80 MW of era capability each year to have the ability to meet the increasing demand. This is much decrease than the capacity of typical CCGTs plants which averages 300-400 MW that should be inbuilt one go, resulting in unnecessary expenditure. Engine energy crops, however, are modular, which implies they can be constructed precisely as and when the country wants them, and additional prolonged when required.
The numbers at play are important. The model shows that If Senegal chooses to favour CCGT plants on the expense of ICE-gas, it’s going to lead to as much as 240 million dollars of extra cost for the system by 2035. The price distinction between the applied sciences can even improve to 350 million USD in favor of ICE know-how if Senegal additionally chooses to construct new renewable vitality capability within the subsequent decade.
Risk-managing potential fuel infrastructure delays

The development of gasoline infrastructure is a posh and lengthy endeavour. Program delays usually are not uncommon, causing fuel supply disruptions that may have a huge financial impression on the operation of CCGT plants.
เกจ์วัดแรงดันน้ำมันเครื่อง is aware of something about that. Only last year, important gasoline supply issues have brought on shutdowns at a few of the country’s largest gas turbine power plants. Because Gas generators function on a steady combustion course of, they require a continuing provide of gasoline and a secure dispatched load to generate consistent power output. If the provision is disrupted, shutdowns happen, placing a great strain on the general system. ICE-Gas plants then again, are designed to regulate their operational profile over time and enhance system flexibility. Because of their flexible operating profile, they were in a place to maintain a much higher stage 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 invest into gasoline engines, the value of gasoline delay would be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in extra cost.
Whichever method you have a look at it, new ICE-Gas generation capability will minimize the whole value of electrical energy in Senegal in all attainable situations. If Senegal is to meet electrical energy demand development in a cost-optimal means, no much less than 300 MW of recent ICE-Gas capability might be required by 2026.
