Senegal’s home fuel reserves will be primarily used to provide electrical energy. Authorities count on that domestic gasoline infrastructure tasks will come on-line between 2025 and 2026, offered there isn’t a delay. The monetization of those important power assets is at the foundation of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä conducted in-depth research that analyse the economic influence of the varied gas-to-power strategies out there to Senegal. Two very totally different technologies are competing to fulfill 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 2 primary gas-to-power technologies the nation is currently contemplating. Contrary to prevailing beliefs, gasoline engines are in reality much better suited than mixed cycle fuel turbines to harness power from Senegal’s new gasoline resources cost-effectively, the examine reveals. Total cost differences between the 2 applied sciences could reach as much as 480 million USD until 2035 relying on situations.
Two competing and really completely different technologies
The state-of-the-art vitality mix models developed by Wärtsilä, which builds customised energy scenarios to identify the cost optimum method to ship new era capacity for a specific nation, reveals 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 reliable, they’re very completely different in phrases of the profiles in which they can function. CCGT is a expertise that has been developed for the interconnected European electricity markets, where it could operate at 90% load factor always. On the opposite hand, flexible ICE expertise can function effectively in all operating profiles, and seamlessly adapt itself to some other era technologies that may make up the country’s power mix.
In explicit our research reveals that when working in an electrical energy network of limited size such as Senegal’s 1GW national grid, counting on CCGTs to considerably expand the network capability would be extremely pricey in all possible situations.
Cost variations between the technologies are defined by numerous elements. First of all, hot climates negatively influence the output of gasoline turbines more than it does that of gas engines.
Secondly, thanks to Senegal’s anticipated access to low cost home gasoline, the working prices turn into much less impactful than the funding prices. In other words, as a end result of low gasoline costs lower operating costs, it’s financially sound for the nation to depend on ICE power vegetation, which are cheaper to construct.
Technology modularity additionally plays a key role. Senegal is expected to require an additional 60-80 MW of era capability annually to find a way to meet the growing demand. This is much lower than the capacity of typical CCGTs crops which averages 300-400 MW that have to be inbuilt one go, resulting in unnecessary expenditure. Engine power plants, then again, are modular, which means they are often constructed precisely as and when the nation wants them, and further prolonged when required.
The numbers at play are important. The model reveals that If Senegal chooses to favour CCGT plants at the expense of ICE-gas, it’ll result in as a lot as 240 million dollars of extra price for the system by 2035. The value distinction between the technologies may even enhance to 350 million USD in favor of ICE technology if Senegal additionally chooses to construct new renewable power capability throughout the next decade.
Risk-managing potential gasoline infrastructure delays
The improvement of fuel infrastructure is a complex and lengthy endeavour. Program delays are not uncommon, inflicting fuel provide disruptions that can have an enormous monetary impression on the operation of CCGT vegetation.
Nigeria is conscious of something about that. Only เกจวัดความดันแก๊ส , significant fuel supply issues have triggered shutdowns at a few of the country’s largest gas turbine power vegetation. Because Gas generators operate on a steady combustion process, they require a relentless supply of gasoline and a secure dispatched load to generate constant power output. If the availability is disrupted, shutdowns happen, putting an excellent pressure on the general system. ICE-Gas crops however, are designed to adjust their operational profile over time and increase system flexibility. Because of their flexible operating profile, they have been able to preserve a a lot larger level of availability
The research took a deep dive to analyse the financial impression of two years delay within the gas infrastructure program. It demonstrates that if the nation decides to speculate into gas engines, the value of gas delay could be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in additional price.
Whichever method you have a look at it, new ICE-Gas era capacity will reduce the entire value of electricity in Senegal in all potential scenarios. If Senegal is to satisfy electricity demand progress in a cost-optimal way, at least 300 MW of recent ICE-Gas capability will be required by 2026.
