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

pressure gauge แบบ น้ำมัน shall be primarily used to supply electricity. Authorities count on that domestic gasoline infrastructure tasks will come online between 2025 and 2026, provided there is no delay. The monetization of these significant vitality assets is on the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide expertise group Wärtsilä performed in-depth studies that analyse the economic impact of the assorted gas-to-power strategies available to Senegal. Two very totally different applied sciences are competing to meet the country’s gas-to-power ambitions: Combined-cycle fuel turbines (CCGT) and Gas engines (ICE).
These studies have revealed very important system value differences between the 2 main gas-to-power technologies the nation is at present contemplating. Contrary to prevailing beliefs, fuel engines are actually much better suited than mixed cycle gas turbines to harness power from Senegal’s new gas assets cost-effectively, the research reveals. Total price variations between the two applied sciences could reach as a lot as 480 million USD until 2035 relying on eventualities.
Two competing and very totally different applied sciences
The state-of-the-art vitality combine fashions developed by Wärtsilä, which builds customised energy scenarios to establish the fee optimal way to deliver new technology capacity for a particular country, reveals that ICE and CCGT technologies current important value variations for the gas-to-power newbuild program running to 2035.
Although these two technologies are equally proven and dependable, they’re very different in terms of the profiles by which they will operate. CCGT is a expertise that has been developed for the interconnected European electricity markets, the place it can operate at 90% load factor always. On the other hand, versatile ICE expertise can operate efficiently in all operating profiles, and seamlessly adapt itself to another technology technologies that can make up the country’s vitality combine.
In specific our research reveals that when operating in an electrical energy network of restricted size such as Senegal’s 1GW national grid, relying on CCGTs to significantly expand the network capability could be extremely costly in all possible situations.
Cost variations between the technologies are defined by a number of elements. First of all, scorching climates negatively influence the output of gasoline generators greater than it does that of gasoline engines.
Secondly, because of Senegal’s anticipated access to low-cost domestic fuel, the operating costs turn out to be much less impactful than the funding prices. In other phrases, because low gasoline prices decrease working prices, it is financially sound for the nation to depend on ICE power plants, that are less expensive to build.
Technology modularity additionally performs a key function. Senegal is predicted to require an additional 60-80 MW of technology capability each year to have the ability to meet the growing demand. This is way decrease than the capacity of typical CCGTs plants which averages 300-400 MW that must be built in one go, leading to unnecessary expenditure. Engine energy vegetation, however, are modular, which means they can be built precisely as and when the country needs them, and further 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’s going to result in as a lot as 240 million dollars of additional price for the system by 2035. The value difference between the technologies may even improve to 350 million USD in favor of ICE technology if Senegal also chooses to build new renewable energy capacity throughout the next decade.
Risk-managing potential fuel infrastructure delays
The improvement of fuel infrastructure is a posh and lengthy endeavour. Program delays usually are not uncommon, inflicting fuel provide disruptions that will have an enormous monetary impact on the operation of CCGT plants.
Nigeria knows one thing about that. Only final yr, significant gasoline provide points have triggered shutdowns at some of the country’s largest gasoline turbine power crops. Because Gas turbines function on a steady combustion course of, they require a constant supply of gasoline and a steady dispatched load to generate consistent energy output. If the provision is disrupted, shutdowns happen, putting a great pressure on the overall system. ICE-Gas crops however, are designed to adjust their operational profile over time and increase system flexibility. Because of their versatile working profile, they have been able to preserve a a lot larger degree of availability
The research took a deep dive to analyse the financial impression of 2 years delay within the gasoline infrastructure program. It demonstrates that if the country decides to speculate into gasoline engines, the price of gasoline delay would be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in extra price.
Whichever way you take a look at it, new ICE-Gas era capability will minimize the entire value of electricity in Senegal in all potential situations. If Senegal is to meet electrical energy demand growth in a cost-optimal means, no much less than 300 MW of latest ICE-Gas capability might be required by 2026.
