Senegal faces key expertise selections in its seek for the optimum gas-to-power strategy

Senegal’s home fuel reserves might be primarily used to supply electrical energy. Authorities count on that home gasoline infrastructure initiatives will come online between 2025 and 2026, supplied there is no delay. The monetization of those vital vitality sources is at the basis of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä carried out in-depth studies that analyse the financial impression of the assorted gas-to-power strategies obtainable to Senegal. เกจวัดแรงดันอากาศ are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gas turbines (CCGT) and Gas engines (ICE).
These research have revealed very vital system price variations between the two primary gas-to-power technologies the nation is at present considering. Contrary to prevailing beliefs, gasoline engines are actually significantly better suited than combined cycle gasoline generators to harness energy from Senegal’s new fuel resources cost-effectively, the examine reveals. Total value differences between the 2 technologies might reach as a lot as 480 million USD till 2035 relying on eventualities.
Two competing and really different technologies
The state-of-the-art vitality mix models developed by Wärtsilä, which builds customised energy scenarios to determine the cost optimal method to deliver new era capability for a particular country, shows that ICE and CCGT applied sciences present significant value variations for the gas-to-power newbuild program operating to 2035.
Although these two technologies are equally confirmed and dependable, they are very totally different when it comes to the profiles during which they can operate. CCGT is a know-how that has been developed for the interconnected European electrical energy markets, the place it can function at 90% load issue always. On the opposite hand, flexible ICE expertise can operate efficiently in all working profiles, and seamlessly adapt itself to any other generation applied sciences that will make up the country’s vitality combine.
In explicit our examine reveals that when working in an electrical energy community of limited dimension corresponding to Senegal’s 1GW nationwide grid, relying on CCGTs to considerably broaden the network capacity could be extremely pricey in all possible situations.
Cost variations between the technologies are explained by a number of components. First of all, hot climates negatively impression the output of fuel turbines more than it does that of gasoline engines.
Secondly, thanks to Senegal’s anticipated entry to cheap home gasoline, the operating costs turn into much less impactful than the investment costs. In other phrases, because low gas costs decrease operating prices, it is financially sound for the nation to rely on ICE energy vegetation, which are inexpensive to build.
Technology modularity additionally plays a key role. Senegal is predicted to require an extra 60-80 MW of era capability every year to have the ability to meet the rising demand. This is far decrease than the capability of typical CCGTs crops which averages 300-400 MW that should be inbuilt one go, resulting in unnecessary expenditure. Engine power crops, on the other hand, are modular, which means they can be constructed precisely as and when the country wants them, and further extended when required.
The numbers at play are vital. The model reveals that If Senegal chooses to favour CCGT vegetation at the expense of ICE-gas, it will result in as a lot as 240 million dollars of additional price for the system by 2035. The price difference between the technologies may even increase to 350 million USD in favor of ICE technology if Senegal also chooses to build new renewable energy capacity throughout the subsequent decade.
Risk-managing potential fuel infrastructure delays
The improvement of gasoline infrastructure is a complex and lengthy endeavour. Program delays aren’t uncommon, causing fuel supply disruptions that may have an enormous monetary impact on the operation of CCGT crops.
Nigeria knows something about that. Only final year, important gas supply issues have caused shutdowns at a variety of the country’s largest fuel turbine energy plants. Because Gas turbines function on a continuous combustion course of, they require a relentless provide of fuel and a secure dispatched load to generate consistent energy output. If the availability is disrupted, shutdowns occur, putting an excellent pressure on the overall system. ICE-Gas plants on the opposite hand, are designed to regulate their operational profile over time and increase system flexibility. Because of their flexible working profile, they have been able to preserve a a lot greater stage of availability
The research took a deep dive to analyse the financial influence of two years delay in the gas infrastructure program. It demonstrates that if the nation decides to invest into gasoline engines, the worth of gas delay could be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in extra cost.
Whichever method you look at it, new ICE-Gas generation capability will reduce the total value of electricity in Senegal in all attainable eventualities. If Senegal is to fulfill electricity demand development in a cost-optimal way, no much less than 300 MW of new ICE-Gas capacity shall be required by 2026.
