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

Senegal’s home fuel reserves might be primarily used to provide electricity. Authorities count on that domestic gas infrastructure tasks will come online between 2025 and 2026, provided there is no delay. The monetization of these significant vitality assets is at the basis of the government’s new gas-to-power ambitions.
In this context, the worldwide know-how group Wärtsilä carried out in-depth studies that analyse the financial influence of the assorted gas-to-power methods out there to Senegal. Two very completely different technologies are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle gas generators (CCGT) and Gas engines (ICE).
These studies have revealed very important system value differences between the two main gas-to-power applied sciences the nation is currently contemplating. Contrary to prevailing beliefs, gas engines are in fact a lot better suited than mixed cycle gasoline generators to harness energy from Senegal’s new gas resources cost-effectively, the research reveals. Total cost differences between the 2 technologies could reach as much as 480 million USD until 2035 relying on eventualities.
Two competing and very different technologies
The state-of-the-art energy combine models developed by Wärtsilä, which builds customised power eventualities to determine the price optimum approach to ship new generation capability for a selected nation, exhibits that ICE and CCGT applied sciences present important value variations for the gas-to-power newbuild program running to 2035.
Although these two applied sciences are equally proven and dependable, they are very different by way of the profiles in which they can operate. CCGT is a expertise that has been developed for the interconnected European electricity markets, where it might possibly function at 90% load factor at all times. On the opposite hand, versatile ICE know-how can function efficiently in all operating profiles, and seamlessly adapt itself to some other era technologies that can make up the country’s vitality mix.
In explicit our research reveals that when working in an electricity community of restricted measurement such as Senegal’s 1GW nationwide grid, counting on CCGTs to significantly broaden the community capacity could be extraordinarily pricey in all potential situations.
Cost differences between the applied sciences are explained by a quantity of factors. First of all, scorching climates negatively influence the output of fuel generators more than it does that of gasoline engines.
Secondly, due to Senegal’s anticipated entry to cheap home gasoline, the working prices become less impactful than the funding costs. In other phrases, because low gasoline costs lower operating costs, it is financially sound for the nation to depend on ICE energy plants, which are inexpensive to construct.
Technology modularity additionally performs a key function. Senegal is predicted to require an additional 60-80 MW of technology capacity each year to find a way to meet the increasing demand. This is far decrease than the capacity of typical CCGTs vegetation which averages 300-400 MW that must be inbuilt one go, leading to unnecessary expenditure. เกจวัดแรงดันน้ำมันเบนซิน , then again, are modular, which suggests they can be constructed exactly as and when the nation wants them, and further prolonged when required.
The numbers at play are important. The mannequin exhibits that If Senegal chooses to favour CCGT crops at the expense of ICE-gas, it’ll lead to as a lot as 240 million dollars of extra price for the system by 2035. The value distinction between the applied sciences may even improve to 350 million USD in favor of ICE know-how if Senegal additionally chooses to build new renewable power capability within the next decade.
Risk-managing potential gasoline infrastructure delays
The improvement of gas infrastructure is a complex and lengthy endeavour. Program delays are not uncommon, causing gasoline provide disruptions that may have a huge financial influence on the operation of CCGT crops.
Nigeria is aware of one thing about that. Only last year, important gasoline supply points have triggered shutdowns at some of the country’s largest fuel turbine power vegetation. Because Gas turbines function on a steady combustion course of, they require a relentless supply of gasoline and a stable dispatched load to generate constant power output. If the availability is disrupted, shutdowns occur, putting an excellent pressure on the overall system. ICE-Gas crops then again, are designed to regulate their operational profile over time and enhance system flexibility. Because of their versatile operating profile, they had been capable of preserve a a lot higher degree of availability
The study 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 fuel engines, the cost of gasoline delay can be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in further price.
Whichever method you take a glance at it, new ICE-Gas generation capability will decrease the whole value of electrical energy in Senegal in all possible situations. If Senegal is to meet electricity demand growth in a cost-optimal way, at least 300 MW of recent ICE-Gas capacity might be required by 2026.
