Senegal’s home fuel reserves shall be primarily used to provide electricity. Authorities anticipate that domestic gasoline infrastructure projects will come on-line between 2025 and 2026, offered there is no delay. The monetization of those significant power resources is on 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 financial impression 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 fuel turbines (CCGT) and Gas engines (ICE).
These studies have revealed very important system price variations between the two primary gas-to-power applied sciences the country is currently contemplating. Contrary to prevailing beliefs, gas engines are in reality much better suited than combined cycle gas turbines to harness power from Senegal’s new fuel assets cost-effectively, the study reveals. เกจวัดแรงดัน between the two applied sciences could reach as a lot as 480 million USD until 2035 depending on scenarios.
Two competing and really totally different technologies
The state-of-the-art power mix fashions developed by Wärtsilä, which builds customised vitality eventualities to establish the cost optimal approach to ship new technology capability for a selected country, exhibits that ICE and CCGT technologies present vital value differences for the gas-to-power newbuild program running to 2035.
Although these two applied sciences are equally proven and reliable, they’re very completely different by way of the profiles in which they will function. CCGT is a technology that has been developed for the interconnected European electrical energy markets, the place it can function at 90% load issue at all times. On the opposite hand, versatile ICE expertise can operate effectively in all operating profiles, and seamlessly adapt itself to another technology technologies that may make up the country’s energy mix.
In explicit our study reveals that when operating in an electricity network of limited size similar to Senegal’s 1GW nationwide grid, counting on CCGTs to significantly increase the network capability could be extraordinarily costly in all potential situations.
Cost variations between the applied sciences are explained by a number of factors. First of all, scorching climates negatively impression the output of gas generators greater than it does that of gasoline engines.
Secondly, because of Senegal’s anticipated entry to cheap home fuel, the operating prices turn into much less impactful than the funding prices. In other phrases, as a outcome of low fuel costs lower working prices, it is financially sound for the nation to rely on ICE energy vegetation, which are inexpensive to construct.
Technology modularity additionally performs a key role. Senegal is predicted to require an extra 60-80 MW of era capacity annually to have the flexibility to meet the growing demand. This is way decrease than the capability of typical CCGTs crops which averages 300-400 MW that have to be inbuilt one go, leading to pointless expenditure. Engine power crops, on the other hand, are modular, which means they are often built precisely as and when the country needs them, and additional prolonged when required.
The numbers at play are significant. The mannequin exhibits that If Senegal chooses to favour CCGT crops on the expense of ICE-gas, it will lead to as much as 240 million dollars of extra value for the system by 2035. The cost difference between the applied sciences can even improve to 350 million USD in favor of ICE expertise if Senegal additionally chooses to construct new renewable vitality capacity inside the next decade.
Risk-managing potential gasoline infrastructure delays
The development of fuel infrastructure is a posh and prolonged endeavour. Program delays are not unusual, causing fuel provide disruptions that can have an enormous financial impression on the operation of CCGT crops.
Nigeria knows something about that. Only last 12 months, vital gas supply issues have caused shutdowns at a number of the country’s largest gas turbine energy crops. Because Gas turbines function on a steady combustion course of, they require a continuing provide of fuel and a stable dispatched load to generate consistent energy output. If the supply is disrupted, shutdowns happen, placing a great pressure on the overall system. ICE-Gas crops however, are designed to adjust their operational profile over time and improve system flexibility. Because of their flexible operating profile, they were able to maintain a a lot greater stage of availability
The study took a deep dive to analyse the financial impact of 2 years delay in the gas infrastructure program. digital pressure gauge demonstrates that if the nation decides to take a position into fuel engines, the price of gasoline delay could be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in further price.
Whichever digital pressure gauge have a glance at it, new ICE-Gas generation capability will reduce the whole price of electrical energy in Senegal in all possible situations. If Senegal is to fulfill electrical energy demand growth in a cost-optimal method, a minimum of 300 MW of new ICE-Gas capacity might be required by 2026.
