Senegal’s home fuel reserves will be mainly used to provide electricity. Authorities anticipate that domestic gasoline infrastructure initiatives will come on-line between 2025 and 2026, offered there isn’t any delay. The monetization of these important energy assets is on the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide technology group Wärtsilä carried out in-depth research that analyse the financial impression of the assorted gas-to-power strategies available to Senegal. Two very completely different applied sciences are competing to fulfill the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These studies have revealed very significant system value differences between the two primary gas-to-power applied sciences the nation is at present contemplating. Contrary to prevailing beliefs, gasoline engines are in fact much better suited than combined cycle gasoline generators to harness energy from Senegal’s new gas sources cost-effectively, the research reveals. Total cost variations between the 2 technologies could attain as a lot as 480 million USD till 2035 depending on eventualities.
Two competing and really different technologies
The state-of-the-art vitality combine models developed by Wärtsilä, which builds customised energy eventualities to determine the price optimum way to deliver new technology capability for a particular nation, shows that ICE and CCGT applied sciences present vital value differences for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally proven and reliable, they are very totally different in phrases of the profiles by which they can function. CCGT is a technology that has been developed for the interconnected European electrical energy markets, the place it may possibly operate at 90% load issue at all times. On the opposite hand, versatile ICE technology can operate efficiently in all working profiles, and seamlessly adapt itself to some other era technologies that can make up the country’s power combine.
In explicit our examine reveals that when working in an electrical energy network of limited size such as Senegal’s 1GW nationwide grid, relying on CCGTs to considerably expand the network capability would be extraordinarily expensive in all potential eventualities.
Cost variations between the applied sciences are explained by a variety of components. First of all, hot climates negatively impact the output of gasoline generators greater than it does that of gasoline engines.
Secondly, due to Senegal’s anticipated access to low-cost domestic fuel, the operating costs become less impactful than the funding prices. In other words, as a outcome of low gas costs decrease operating prices, it is financially sound for the country to rely on ICE energy plants, which are less expensive to construct.
Technology modularity additionally plays a key function. Senegal is predicted to require an additional 60-80 MW of era capacity each year to have the ability to meet the rising demand. This is far decrease than the capability of typical CCGTs plants which averages 300-400 MW that should be inbuilt one go, resulting in pointless expenditure. Engine power vegetation, then again, are modular, which suggests they can be constructed exactly as and when the country needs them, and additional prolonged when required.
The numbers at play are vital. The model shows 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 additional value for the system by 2035. The value difference between the technologies may even enhance to 350 million USD in favor of ICE technology if Senegal also chooses to construct new renewable energy capacity within the next decade.
Risk-managing เกวัดแรงดัน delays
The growth of fuel infrastructure is a posh and prolonged endeavour. Program delays aren’t uncommon, causing gas provide disruptions that will have a huge monetary impression on the operation of CCGT crops.
Nigeria is conscious of one thing about that. Only final year, significant gasoline provide points have triggered shutdowns at a number of the country’s largest fuel turbine energy vegetation. Because Gas turbines operate on a steady combustion process, they require a continuing supply of gas and a stable dispatched load to generate consistent energy output. If the provision is disrupted, shutdowns happen, placing a fantastic strain on the overall system. ICE-Gas crops then again, are designed to regulate their operational profile over time and increase system flexibility. Because of their versatile operating profile, they were able to maintain a much higher degree of availability
The research took a deep dive to analyse the financial impact of 2 years delay within the fuel infrastructure program. It demonstrates that if the nation decides to invest into gasoline engines, the value of gas delay would be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in additional cost.
Whichever way you look at it, new ICE-Gas era capability will decrease the whole price of electricity in Senegal in all possible situations. If Senegal is to satisfy electrical energy demand growth in a cost-optimal means, no less than 300 MW of new ICE-Gas capability shall be required by 2026.
