Senegal faces key technology choices in its search for the optimal gas-to-power technique

Senegal’s home gasoline reserves might be primarily used to provide electrical energy. Authorities count on that domestic gasoline infrastructure projects will come online between 2025 and 2026, provided there is not a delay. The monetization of these vital vitality resources is at the foundation of the government’s new gas-to-power ambitions.
In เกจวัดco2 , the global technology group Wärtsilä carried out in-depth studies that analyse the financial impression of the varied gas-to-power strategies 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 studies have revealed very vital system value differences between the two major gas-to-power applied sciences the nation is presently considering. Contrary to prevailing beliefs, fuel engines are in fact much better suited than combined cycle gasoline generators to harness power from Senegal’s new gas resources cost-effectively, the research reveals. Total price differences between the 2 technologies may attain as much as 480 million USD till 2035 depending on scenarios.
Two competing and really totally different technologies
The state-of-the-art energy combine models developed by Wärtsilä, which builds customised energy situations to establish the price optimum approach to ship new technology capacity for a particular country, reveals that ICE and CCGT technologies present important value variations for the gas-to-power newbuild program operating to 2035.
Although these two applied sciences are equally proven and reliable, they are very different when it comes to the profiles by which they’ll function. CCGT is a expertise that has been developed for the interconnected European electricity markets, where it could function at 90% load issue at all times. On the opposite hand, flexible ICE know-how can function efficiently in all working profiles, and seamlessly adapt itself to some other generation applied sciences that will make up the country’s power combine.
In particular our research reveals that when operating in an electricity community of limited size similar to Senegal’s 1GW nationwide grid, counting on CCGTs to significantly expand the community capability could be extraordinarily pricey in all potential situations.
Cost variations between the technologies are explained by a quantity of elements. First of all, hot climates negatively influence the output of fuel turbines more than it does that of gasoline engines.
Secondly, because of Senegal’s anticipated access to low cost home gasoline, the working prices become much less impactful than the investment costs. In different words, as a end result of low gasoline costs decrease working costs, it is financially sound for the nation to rely on ICE power crops, that are cheaper to build.
Technology modularity additionally plays a key position. Senegal is predicted to require an additional 60-80 MW of technology capability annually to be able to meet the increasing demand. This is much lower than the capacity of typical CCGTs crops which averages 300-400 MW that should be built in one go, resulting in pointless expenditure. Engine power crops, then again, are modular, which means they can be constructed precisely as and when the nation wants them, and further prolonged when required.
The numbers at play are vital. The model exhibits that If Senegal chooses to favour CCGT plants on the expense of ICE-gas, it’s going to lead to as a lot as 240 million dollars of additional value for the system by 2035. The value distinction between the technologies may even improve to 350 million USD in favor of ICE expertise if Senegal also chooses to build new renewable energy capability throughout the next decade.
Risk-managing potential gas infrastructure delays
The growth of gasoline infrastructure is a fancy and prolonged endeavour. Program delays usually are not uncommon, causing gas supply disruptions that may have an enormous monetary impact on the operation of CCGT crops.
Nigeria knows something about that. Only final yr, vital fuel supply issues have brought on shutdowns at a few of the country’s largest gas turbine energy plants. Because Gas generators function on a steady combustion course of, they require a continuing provide of fuel and a secure dispatched load to generate constant energy output. If the supply is disrupted, shutdowns occur, placing a fantastic strain on the overall system. ICE-Gas crops on the opposite hand, are designed to regulate their operational profile over time and improve system flexibility. Because of their versatile operating profile, they have been capable of keep a much greater degree of availability
The research took a deep dive to analyse the financial influence of two years delay in the gasoline infrastructure program. It demonstrates that if the nation decides to speculate into gas engines, the price of gas delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further cost.
Whichever way you look at it, new ICE-Gas technology capability will decrease the whole cost of electrical energy in Senegal in all potential eventualities. If Senegal is to satisfy electrical energy demand progress in a cost-optimal means, a minimum of 300 MW of new ICE-Gas capacity shall be required by 2026.
