Senegal faces key know-how decisions in its seek for the optimal gas-to-power strategy

Senegal’s domestic gas reserves will be primarily used to provide electricity. Authorities count on that domestic fuel infrastructure initiatives will come on-line between 2025 and 2026, provided there isn’t any delay. The monetization of those vital energy sources is on the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide know-how group Wärtsilä conducted in-depth research that analyse the financial impact of the assorted gas-to-power methods obtainable to Senegal. Two very totally different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These studies have revealed very vital system price differences between the two major gas-to-power technologies the country is currently considering. Contrary to prevailing beliefs, fuel engines are actually a lot better suited than mixed cycle fuel generators to harness power from Senegal’s new gas assets cost-effectively, the research reveals. Total price variations between the 2 technologies might attain as a lot as 480 million USD till 2035 depending on eventualities.
Two competing and very completely different technologies
The state-of-the-art vitality mix models developed by Wärtsilä, which builds customised power scenarios to establish the cost optimal way to ship new era capability for a particular nation, exhibits that ICE and CCGT applied sciences present vital value differences for the gas-to-power newbuild program working to 2035.
Although these two technologies are equally proven and dependable, they’re very completely different when it comes to the profiles by which they can operate. CCGT is a know-how that has been developed for the interconnected European electricity markets, where it may possibly operate at 90% load issue at all times. On the other hand, versatile ICE know-how can function efficiently in all operating profiles, and seamlessly adapt itself to another technology applied sciences that will make up the country’s power mix.
In explicit our study reveals that when operating in an electrical energy community of restricted measurement similar to Senegal’s 1GW national grid, counting on CCGTs to considerably expand the community capacity can be extraordinarily costly in all possible scenarios.
Cost differences between the technologies are explained by a selection of components. First of all, hot climates negatively impact the output of gasoline turbines greater than it does that of fuel engines.
Secondly, thanks to Senegal’s anticipated entry to low cost domestic gasoline, the operating costs turn into much less impactful than the funding costs. In different words, because low fuel prices lower working prices, it is financially sound for the country to depend on ICE energy crops, that are less expensive to construct.
Technology modularity additionally plays a key function. Senegal is anticipated to require an additional 60-80 MW of technology capability every year to have the flexibility to meet the rising demand. This is way decrease than the capability of typical CCGTs crops which averages 300-400 MW that have to be built in one go, resulting in pointless expenditure. Engine power crops, on the other hand, are modular, which means they are often built precisely as and when the nation needs them, and additional prolonged when required.
The numbers at play are significant. The model exhibits that If Senegal chooses to favour CCGT crops on the expense of ICE-gas, it’ll result in as much as 240 million dollars of extra value for the system by 2035. pressure gauge 0 10 bar ราคา between the applied sciences may even enhance to 350 million USD in favor of ICE expertise if Senegal also chooses to build new renewable energy capacity within the next decade.
Risk-managing potential fuel infrastructure delays
The development of gasoline infrastructure is a complex and lengthy endeavour. Program delays are not uncommon, causing fuel provide disruptions that can have an enormous monetary impression on the operation of CCGT vegetation.
Nigeria is aware of something about that. Only final 12 months, important fuel supply issues have brought on shutdowns at a few of the country’s largest gasoline turbine power vegetation. Because Gas generators operate on a steady combustion process, they require a constant provide of gasoline and a stable dispatched load to generate constant power output. If the supply is disrupted, shutdowns happen, putting an excellent pressure on the general system. ICE-Gas vegetation however, are designed to regulate their operational profile over time and improve system flexibility. Because of their versatile working profile, they have been in a place to maintain a a lot larger level of availability
The examine took a deep dive to analyse the monetary influence of two years delay within the gasoline infrastructure program. It demonstrates that if the nation decides to invest into gasoline 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 additional price.
Whichever method you look at it, new ICE-Gas generation capacity will decrease the whole price of electrical energy in Senegal in all possible eventualities. If Senegal is to meet electricity demand progress in a cost-optimal method, a minimal of 300 MW of new ICE-Gas capability will be required by 2026.
