Senegal faces key technology selections in its seek for the optimum gas-to-power technique

Senegal’s home fuel reserves will be primarily used to provide electricity. Authorities expect that home gas infrastructure initiatives will come on-line between 2025 and 2026, supplied there isn’t a delay. The monetization of these significant energy assets is on the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide technology group Wärtsilä carried out in-depth studies that analyse the economic influence of the various gas-to-power methods available to Senegal. Two very totally different technologies are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These research have revealed very important system price variations between the two major gas-to-power technologies the nation is currently considering. Contrary to prevailing beliefs, gasoline engines are in reality much better suited than combined cycle fuel turbines to harness power from Senegal’s new gasoline sources cost-effectively, the examine reveals. Total cost variations between the 2 applied sciences could reach as a lot as 480 million USD till 2035 relying on situations.
Two competing and very totally different applied sciences
The state-of-the-art vitality combine models developed by Wärtsilä, which builds customised energy scenarios to determine the fee optimum approach to deliver new era capability for a specific nation, exhibits that ICE and CCGT technologies present vital cost differences for the gas-to-power newbuild program running to 2035.
Although these two technologies are equally confirmed and reliable, they’re very totally different in phrases of the profiles in which they’ll operate. CCGT is a expertise that has been developed for the interconnected European electricity markets, the place it can operate at 90% load factor at all times. On the opposite hand, flexible ICE technology can operate efficiently in all operating profiles, and seamlessly adapt itself to another technology applied sciences that can make up the country’s energy mix.
In particular our research reveals that when operating in an electrical energy network of limited dimension such as Senegal’s 1GW nationwide grid, relying on CCGTs to significantly increase the community capacity can be extraordinarily pricey in all possible scenarios.
Cost variations between the applied sciences are defined by a number of factors. First of ราคาเพรสเชอร์เกจ , hot climates negatively influence the output of fuel turbines greater than it does that of gas engines.
Secondly, thanks to Senegal’s anticipated entry to low-cost home gasoline, the working costs become less impactful than the investment prices. In other phrases, because low gasoline prices decrease working prices, it is financially sound for the country to rely on ICE power plants, which are cheaper to construct.
Technology modularity also performs a key role. Senegal is anticipated to require an additional 60-80 MW of generation capacity each year to have the power to meet the increasing demand. This is much lower than the capability of typical CCGTs plants which averages 300-400 MW that must be inbuilt one go, resulting in pointless expenditure. Engine energy plants, however, are modular, which implies they can be constructed exactly as and when the country wants them, and additional prolonged when required.
The numbers at play are significant. เกจวัดแรงดันลมดิจิตอล shows that If Senegal chooses to favour CCGT vegetation at the expense of ICE-gas, it will result in as much as 240 million dollars of extra price for the system by 2035. The cost difference between the technologies may even improve to 350 million USD in favor of ICE technology if Senegal also chooses to construct new renewable energy capacity throughout the subsequent decade.
Risk-managing potential gasoline infrastructure delays
The improvement of gas infrastructure is a complex and lengthy endeavour. Program delays are not unusual, causing gasoline provide disruptions that will have an enormous financial impression on the operation of CCGT crops.
Nigeria knows something about that. Only final year, vital gas supply points have caused shutdowns at a few of the country’s largest fuel turbine power crops. Because Gas turbines operate on a continuous combustion process, they require a relentless provide of gas and a stable dispatched load to generate constant energy output. If the provision is disrupted, shutdowns happen, putting a fantastic pressure on the overall system. ICE-Gas plants however, are designed to adjust their operational profile over time and improve system flexibility. Because of their versatile working profile, they had been in a position to maintain a much larger stage of availability
The research took a deep dive to analyse the financial influence of 2 years delay within the gasoline infrastructure program. It demonstrates that if the country decides to speculate into gas engines, the cost of gas delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further price.
Whichever means you take a glance at it, new ICE-Gas generation capacity will reduce the total price of electrical energy in Senegal in all attainable eventualities. If Senegal is to satisfy electrical energy demand progress in a cost-optimal way, no less than 300 MW of recent ICE-Gas capacity shall be required by 2026.
