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

Senegal’s domestic gas reserves will be primarily used to produce electrical energy. Authorities count on that domestic gasoline infrastructure projects will come on-line between 2025 and 2026, offered there isn’t a delay. The monetization of those important energy assets is on the foundation of the government’s new gas-to-power ambitions.
In this context, the global expertise group Wärtsilä carried out in-depth studies that analyse the financial impact of the assorted gas-to-power strategies obtainable to Senegal. เกจวัดถังแก๊ส are competing to meet the country’s gas-to-power ambitions: Combined-cycle gas generators (CCGT) and Gas engines (ICE).
These research have revealed very vital system cost differences between the 2 major gas-to-power applied sciences the country is currently considering. Contrary to prevailing beliefs, fuel engines are actually a lot better suited than combined cycle gasoline turbines to harness energy from Senegal’s new gasoline sources cost-effectively, the examine reveals. Total value differences between the 2 technologies might attain as a lot as 480 million USD until 2035 relying on eventualities.
Two competing and very completely different applied sciences
The state-of-the-art power combine models developed by Wärtsilä, which builds customised power eventualities to establish the cost optimum approach to deliver new era capacity for a particular country, exhibits that ICE and CCGT technologies current significant price variations for the gas-to-power newbuild program working to 2035.
Although these two technologies are equally proven and reliable, they are very totally different by method of the profiles in which they will operate. CCGT is a know-how that has been developed for the interconnected European electricity markets, the place it can perform at 90% load issue at all times. On the opposite hand, versatile ICE know-how can operate effectively in all operating profiles, and seamlessly adapt itself to another era applied sciences that may make up the country’s energy mix.
In explicit our research reveals that when operating in an electricity network of limited size similar to Senegal’s 1GW nationwide grid, relying on CCGTs to considerably broaden the network capacity could be extremely expensive in all possible scenarios.
Cost differences between the technologies are defined by a quantity of components. First of all, scorching climates negatively impact the output of gas generators greater than it does that of fuel engines.
Secondly, due to Senegal’s anticipated access to low-cost home gasoline, the working prices turn out to be less impactful than the funding prices. In different words, because low gasoline prices lower operating costs, it is financially sound for the country to rely on ICE energy plants, that are inexpensive to build.
Technology modularity additionally plays a key position. Senegal is expected to require an additional 60-80 MW of generation capacity annually to have the ability to meet the increasing demand. This is far lower than the capability of typical CCGTs vegetation which averages 300-400 MW that must be inbuilt one go, leading to pointless expenditure. Engine power crops, however, are modular, which implies they are often constructed exactly as and when the nation needs them, and further prolonged when required.
The numbers at play are important. The model shows that If Senegal chooses to favour CCGT vegetation on the expense of ICE-gas, it will lead to as much as 240 million dollars of extra cost for the system by 2035. The cost distinction between the applied sciences may even increase to 350 million USD in favor of ICE know-how if Senegal additionally chooses to build new renewable power capability throughout the subsequent decade.
Risk-managing potential fuel infrastructure delays
The growth of gas infrastructure is a fancy and prolonged endeavour. Program delays are not uncommon, causing gas supply disruptions that can have an enormous financial impression on the operation of CCGT vegetation.
Nigeria knows one thing about that. Only last yr, important gas provide points have brought on shutdowns at a number of the country’s largest gasoline turbine power vegetation. Because Gas turbines operate on a steady combustion process, they require a continuing provide of gasoline and a steady dispatched load to generate consistent power output. If the availability is disrupted, shutdowns occur, putting an excellent strain on the overall system. ICE-Gas plants then again, are designed to regulate their operational profile over time and improve system flexibility. Because of their flexible working profile, they were in a place to maintain a a lot greater level of availability
The study took a deep dive to analyse the monetary impact of 2 years delay within the gas infrastructure program. It demonstrates that if the country decides to invest into gasoline engines, the value of fuel delay can be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in additional price.
Whichever means you look at it, new ICE-Gas technology capability will decrease the entire cost of electricity in Senegal in all possible eventualities. If Senegal is to fulfill electricity demand progress in a cost-optimal means, a minimal of 300 MW of recent ICE-Gas capacity will be required by 2026.
