Senegal faces key technology choices in its seek for the optimum gas-to-power strategy

Senegal’s home fuel reserves might be primarily used to provide electrical energy. Authorities anticipate that home gasoline infrastructure initiatives will come online between 2025 and 2026, offered there is not a delay. The monetization of these important energy resources is at the foundation of the government’s new gas-to-power ambitions.
In this context, the global know-how group Wärtsilä carried out in-depth research that analyse the economic impact of the various gas-to-power methods available to Senegal. Two very completely different applied sciences are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle fuel turbines (CCGT) and Gas engines (ICE).
These research have revealed very important system cost variations between the two primary gas-to-power applied sciences the country is presently contemplating. Contrary to prevailing beliefs, fuel engines are in fact a lot better suited than combined cycle gasoline generators to harness energy from Senegal’s new gasoline sources cost-effectively, the study reveals. Total cost differences between the 2 technologies could attain as a lot as 480 million USD until 2035 relying on scenarios.
Two competing and really totally different applied sciences
The state-of-the-art energy mix fashions developed by Wärtsilä, which builds customised power scenarios to identify the cost optimal way to ship new technology capacity for a selected country, shows that ICE and CCGT technologies current vital value variations for the gas-to-power newbuild program running to 2035.
Although these two applied sciences are equally confirmed and dependable, they’re very different in phrases of the profiles by which they will operate. CCGT is a know-how that has been developed for the interconnected European electrical energy markets, the place it could possibly function at 90% load issue at all times. On the opposite hand, versatile ICE expertise can operate efficiently in all working profiles, and seamlessly adapt itself to some other generation technologies that can make up the country’s energy combine.
In particular our research reveals that when working in an electricity network of limited size such as Senegal’s 1GW nationwide grid, counting on CCGTs to considerably broaden the community capacity can be extremely pricey in all possible scenarios.
Cost differences between the technologies are defined by a variety of components. First of all, scorching climates negatively influence the output of gasoline generators greater than it does that of fuel engines.
Secondly, due to Senegal’s anticipated entry to low cost domestic gasoline, the working prices become less impactful than the funding costs. In เพรสเชอร์เกจวัดแรงดันน้ำ , as a outcome of low fuel prices decrease working prices, it’s financially sound for the nation to rely on ICE power vegetation, which are less expensive to construct.
Technology modularity also plays a key position. Senegal is anticipated to require an additional 60-80 MW of technology capacity each year to find a way to meet the increasing demand. This is much lower than the capacity of typical CCGTs vegetation which averages 300-400 MW that must be inbuilt one go, leading to unnecessary expenditure. Engine energy plants, on the other hand, are modular, which suggests they can be constructed precisely as and when the nation wants them, and additional prolonged when required.
The numbers at play are important. The mannequin shows that If Senegal chooses to favour CCGT crops at the expense of ICE-gas, it’s going to lead to as much as 240 million dollars of additional cost for the system by 2035. The cost difference between the applied sciences can even enhance to 350 million USD in favor of ICE know-how if Senegal additionally chooses to construct new renewable vitality capacity throughout the next decade.
Risk-managing potential gasoline infrastructure delays
The improvement of fuel infrastructure is a posh and lengthy endeavour. เกจวัดแรงดันpressuregauge delays aren’t unusual, inflicting gas supply disruptions that may have an enormous monetary impression on the operation of CCGT vegetation.
Nigeria is aware of something about that. Only final 12 months, vital fuel provide points have brought on shutdowns at some of the country’s largest gasoline turbine energy vegetation. Because Gas turbines function on a continuous combustion process, they require a relentless provide of gasoline and a steady dispatched load to generate constant energy output. If the provision is disrupted, shutdowns happen, placing a fantastic strain on the general system. ICE-Gas vegetation then again, are designed to regulate their operational profile over time and improve system flexibility. Because of their flexible operating profile, they were in a position to preserve a a lot larger level of availability
The examine took a deep dive to analyse the financial influence of 2 years delay in the gasoline infrastructure program. It demonstrates that if the nation decides to speculate into gasoline engines, the cost of fuel delay could be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in additional value.
Whichever method you have a look at it, new ICE-Gas era capability will reduce the whole value of electrical energy in Senegal in all attainable eventualities. If Senegal is to meet electrical energy demand growth in a cost-optimal means, no less than 300 MW of recent ICE-Gas capacity might be required by 2026.
