Senegal faces key know-how choices in its seek for the optimal gas-to-power technique

Senegal’s home gas reserves might be primarily used to supply electricity. Authorities expect that home gas infrastructure tasks will come online between 2025 and 2026, supplied there is no delay. The monetization of these vital vitality assets is at the foundation of the government’s new gas-to-power ambitions.
In this context, the global know-how group Wärtsilä performed in-depth research that analyse the financial influence of the varied gas-to-power methods available to Senegal. Two very different applied sciences are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gas generators (CCGT) and Gas engines (ICE).
These studies have revealed very significant system price differences between the 2 main gas-to-power applied sciences the country is at present considering. Contrary to prevailing beliefs, fuel engines are in fact much better suited than combined cycle gasoline generators to harness power from Senegal’s new fuel sources cost-effectively, the research reveals. Total cost variations between the 2 technologies may reach as a lot as 480 million USD till 2035 depending on situations.
Two competing and really totally different applied sciences
The state-of-the-art power mix models developed by Wärtsilä, which builds customised vitality eventualities to determine the cost optimum method to deliver new technology capability for a selected nation, shows that ICE and CCGT applied sciences current important value differences for the gas-to-power newbuild program operating to 2035.
Although these two applied sciences are equally proven and dependable, they’re very completely different in phrases of the profiles by which they can operate. CCGT is a know-how that has been developed for the interconnected European electrical energy markets, the place it may possibly operate at 90% load factor always. On the opposite hand, versatile ICE technology can operate efficiently in all operating profiles, and seamlessly adapt itself to another era applied sciences that can make up the country’s vitality combine.
In specific our study reveals that when working in an electricity community of restricted measurement such as Senegal’s 1GW national grid, relying on CCGTs to considerably increase the community capacity could be extraordinarily pricey in all attainable scenarios.
Cost differences between the applied sciences are explained by a number of elements. First of all, sizzling climates negatively influence the output of fuel generators greater than it does that of fuel engines.
Secondly, thanks to Senegal’s anticipated access to low-cost home fuel, the working costs become much less impactful than the investment costs. In เกจวัดแรงดันแก๊สco2 , as a end result of low gasoline costs decrease working costs, it is financially sound for the nation to rely on ICE power crops, which are inexpensive to construct.
Technology modularity additionally plays a key role. Senegal is predicted to require an extra 60-80 MW of era capability each year to have the ability to meet the rising demand. This is way decrease than the capacity of typical CCGTs plants which averages 300-400 MW that have to be in-built one go, leading to pointless expenditure. Engine power plants, then again, are modular, which implies they can be constructed precisely as and when the country needs them, and further extended when required.
The numbers at play are vital. The model shows that If Senegal chooses to favour CCGT crops at the expense of ICE-gas, it’s going to lead to as a lot as 240 million dollars of extra value for the system by 2035. The cost distinction between the technologies may even improve 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 development of gas infrastructure is a fancy and lengthy endeavour. Program delays usually are not uncommon, causing gas provide disruptions that can have an enormous financial impact on the operation of CCGT crops.
Nigeria knows one thing about that. Only last year, vital gasoline supply issues have triggered shutdowns at some of the country’s largest gas turbine energy crops. Because Gas turbines function on a steady combustion course of, they require a relentless supply of fuel and a steady dispatched load to generate constant power output. If the availability is disrupted, shutdowns happen, placing a great pressure on the overall system. ICE-Gas vegetation then again, are designed to regulate their operational profile over time and increase system flexibility. Because of their flexible working profile, they were able to preserve a a lot greater stage of availability
The study took a deep dive to analyse the monetary impression of two years delay within the gasoline infrastructure program. It demonstrates that if the country decides to speculate into fuel engines, the price of gas delay can be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in additional value.
Whichever method you look at it, new ICE-Gas technology capability will minimize the entire cost of electrical energy in Senegal in all potential situations. If Senegal is to fulfill electricity demand development in a cost-optimal means, a minimum of 300 MW of latest ICE-Gas capacity shall be required by 2026.
