Senegal’s home gas reserves shall be primarily used to produce electricity. Authorities anticipate that home fuel infrastructure tasks will come on-line between 2025 and 2026, provided there isn’t any delay. The monetization of these significant power sources is on the basis of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä performed in-depth research that analyse the financial influence of the assorted gas-to-power methods available to Senegal. Two very totally 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 cost differences between the two primary gas-to-power applied sciences the country is currently contemplating. Contrary to prevailing beliefs, gas engines are actually significantly better suited than combined cycle fuel turbines to harness energy from Senegal’s new fuel resources cost-effectively, the study reveals. Total price differences between the 2 technologies could reach as much as 480 million USD till 2035 relying on situations.
Two competing and very different technologies
The state-of-the-art energy mix fashions developed by Wärtsilä, which builds customised energy eventualities to determine the fee optimum method to ship new era capability for a particular nation, exhibits that ICE and CCGT technologies present vital cost differences for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally confirmed and dependable, they’re very totally different when it comes to the profiles in which they will operate. CCGT is a expertise that has been developed for the interconnected European electrical energy markets, where it can function at 90% load factor at all times. On the opposite hand, flexible ICE technology can operate effectively in all working profiles, and seamlessly adapt itself to another generation technologies that can make up the country’s vitality combine.
In specific our study reveals that when operating in an electricity community of limited measurement similar to Senegal’s 1GW nationwide grid, relying on CCGTs to significantly increase the community capability would be extraordinarily costly in all attainable scenarios.
Cost differences between the applied sciences are defined by a number of elements. First of all, hot climates negatively impression the output of gas turbines greater than it does that of gasoline engines.
Secondly, due to Senegal’s anticipated access to low cost home fuel, the working costs turn into much less impactful than the funding costs. In เกจ์วัดแก๊สหุงต้ม , as a result of low gas prices decrease operating prices, it is financially sound for the nation to rely on ICE power crops, that are less expensive to construct.
Technology modularity also performs a key position. Senegal is expected to require an additional 60-80 MW of generation capacity annually to have the power 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. Engine power vegetation, however, are modular, which implies they can be constructed precisely as and when the country needs them, and further prolonged when required.
The numbers at play are important. The mannequin shows that If Senegal chooses to favour CCGT vegetation at the expense of ICE-gas, it’s going to result in as much as 240 million dollars of extra price for the system by 2035. The price distinction between the technologies may even enhance to 350 million USD in favor of ICE expertise if Senegal also chooses to build new renewable power capacity throughout the next decade.
Risk-managing potential gasoline infrastructure delays
The improvement of gas infrastructure is a posh and prolonged endeavour. Program delays are not uncommon, inflicting gasoline supply disruptions that may have an enormous monetary impression on the operation of CCGT plants.
Nigeria is conscious of one thing about that. Only last 12 months, important gasoline provide issues have caused shutdowns at a variety of the country’s largest gas turbine energy crops. Because Gas generators operate on a steady combustion process, they require a relentless provide of gasoline and a secure dispatched load to generate consistent power output. If the availability is disrupted, shutdowns occur, putting an excellent pressure on the general system. ICE-Gas crops on the opposite hand, are designed to adjust their operational profile over time and increase system flexibility. Because of their versatile working profile, they were capable of preserve a a lot larger degree of availability
The study took a deep dive to analyse the monetary impression of two years delay in the gasoline infrastructure program. It demonstrates that if the nation decides to take a position into fuel engines, the value of gas delay would be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in further value.
Whichever method you take a glance at it, new ICE-Gas technology capability will decrease the whole price of electricity in Senegal in all potential scenarios. If Senegal is to fulfill electricity demand development in a cost-optimal means, no much less than 300 MW of new ICE-Gas capacity will be required by 2026.
