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

Senegal’s home gasoline reserves shall be primarily used to supply electricity. Authorities count on that home gasoline infrastructure initiatives will come online between 2025 and 2026, offered there is no delay. The monetization of those important power resources is at the basis of the government’s new gas-to-power ambitions.
In this context, the global expertise group Wärtsilä carried out in-depth studies that analyse the financial influence of the assorted gas-to-power methods available to Senegal. Two very totally different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gasoline generators (CCGT) and Gas engines (ICE).
These research have revealed very important system price differences between the 2 major gas-to-power technologies the nation is at present considering. Contrary to prevailing beliefs, gas engines are in fact a lot better suited than combined cycle gasoline turbines to harness power from Senegal’s new fuel resources cost-effectively, the research reveals. Total value variations between the 2 applied sciences might reach as much as 480 million USD until 2035 relying on eventualities.
Two competing and really completely different applied sciences
The state-of-the-art energy mix models developed by Wärtsilä, which builds customised vitality eventualities to determine the price optimal method to ship new technology capacity for a particular country, shows that ICE and CCGT technologies current important cost differences for the gas-to-power newbuild program operating to 2035.
Although these two technologies are equally confirmed and reliable, they’re very totally different by method of the profiles in which they’ll function. CCGT is a technology that has been developed for the interconnected European electricity markets, where it might possibly perform at 90% load issue at all times. On the opposite hand, versatile ICE know-how can function effectively in all working profiles, and seamlessly adapt itself to another era applied sciences that may make up the country’s energy combine.
In เกจวัดแรงดันเครื่องกรองน้ำ reveals that when working in an electricity community of restricted measurement corresponding to Senegal’s 1GW national grid, counting on CCGTs to considerably increase the network capability can be extremely costly in all attainable eventualities.
Cost differences between the technologies are explained by numerous components. First of all, hot climates negatively impression the output of fuel turbines more than it does that of fuel engines.
Secondly, thanks to Senegal’s anticipated entry to cheap domestic gasoline, the operating costs turn into much less impactful than the investment prices. In different words, because low gas costs decrease operating prices, it’s financially sound for the country to depend on ICE power crops, that are cheaper to build.
Technology modularity also plays a key position. Senegal is expected to require an extra 60-80 MW of technology capability every year to find a way to meet the rising demand. This is far decrease than the capability of typical CCGTs crops which averages 300-400 MW that must be built in one go, leading to pointless expenditure. Engine energy crops, however, are modular, which implies they are often built exactly as and when the country needs them, and additional prolonged when required.
The numbers at play are important. The model exhibits that If Senegal chooses to favour CCGT vegetation on the expense of ICE-gas, it’ll lead to as much as 240 million dollars of extra price for the system by 2035. หลักการทํางานของpressuregauge between the technologies can even improve to 350 million USD in favor of ICE expertise if Senegal also chooses to construct new renewable energy capacity throughout the next decade.
Risk-managing potential gas infrastructure delays
The development of gasoline infrastructure is a complex and lengthy endeavour. Program delays are not uncommon, causing gasoline supply disruptions that may have a huge monetary impact on the operation of CCGT plants.
Nigeria knows one thing about that. Only last yr, important gas supply issues have triggered shutdowns at a few of the country’s largest fuel turbine energy crops. Because Gas generators function on a steady combustion process, they require a continuing provide of fuel and a secure dispatched load to generate constant power output. If the supply is disrupted, shutdowns occur, placing a great pressure on the overall system. ICE-Gas vegetation on the other hand, are designed to adjust their operational profile over time and improve system flexibility. Because of their flexible working profile, they have been able to preserve a much 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 gas engines, the worth of gasoline delay could be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in additional value.
Whichever method you take a look at it, new ICE-Gas technology capacity will decrease the entire cost of electricity in Senegal in all potential eventualities. If Senegal is to meet electricity demand development in a cost-optimal method, at least 300 MW of latest ICE-Gas capability shall be required by 2026.
