Senegal faces key technology selections in its search for the optimum gas-to-power strategy

Senegal’s home gas reserves might be primarily used to supply electricity. Authorities anticipate that domestic fuel infrastructure tasks will come online between 2025 and 2026, offered there is no delay. เกจวัดแรงดันน้ำราคา of these significant energy sources is at the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide expertise group Wärtsilä conducted in-depth research that analyse the economic impression of the assorted gas-to-power methods out there to Senegal. Two very completely different technologies are competing to meet the country’s gas-to-power ambitions: Combined-cycle gas generators (CCGT) and Gas engines (ICE).
These research have revealed very important system price differences between the 2 primary gas-to-power technologies the nation is presently contemplating. Contrary to prevailing beliefs, fuel engines are actually a lot better suited than combined cycle gasoline turbines to harness energy from Senegal’s new fuel sources cost-effectively, the research reveals. Total price variations between the two applied sciences may reach as a lot as 480 million USD till 2035 depending on situations.
Two competing and really totally different technologies
The state-of-the-art power mix fashions developed by Wärtsilä, which builds customised power scenarios to identify the cost optimum method to deliver new technology capacity for a specific country, exhibits that ICE and CCGT technologies present important value differences for the gas-to-power newbuild program working to 2035.
Although these two technologies are equally confirmed and dependable, they’re very completely different by way of the profiles during which they can operate. CCGT is a technology that has been developed for the interconnected European electrical energy markets, where it could possibly perform at 90% load factor always. On the opposite hand, flexible ICE technology can operate effectively in all operating profiles, and seamlessly adapt itself to some other generation applied sciences that will make up the country’s energy mix.
In specific our study reveals that when working in an electrical energy community of limited measurement such as Senegal’s 1GW nationwide grid, relying on CCGTs to considerably broaden the network capability would be extremely expensive in all possible situations.
Cost variations between the technologies are explained by numerous factors. First of all, sizzling climates negatively impact the output of gas generators more than it does that of gasoline engines.
Secondly, thanks to Senegal’s anticipated access to cheap home gasoline, the working costs turn into much less impactful than the investment costs. In different words, as a outcome of low fuel prices decrease working costs, it’s financially sound for the nation to depend on ICE power crops, which are inexpensive to construct.
Technology modularity also performs a key role. Senegal is predicted to require an extra 60-80 MW of generation capacity each year to have the ability to meet the growing demand. This is much decrease than the capability of typical CCGTs plants which averages 300-400 MW that have to be inbuilt one go, resulting in unnecessary expenditure. Engine power plants, however, are modular, which suggests they are often built precisely as and when the country needs them, and additional prolonged when required.
The numbers at play are vital. The model reveals that If Senegal chooses to favour CCGT vegetation at the expense of ICE-gas, it’ll lead to as a lot as 240 million dollars of additional price for the system by 2035. The price distinction between the applied sciences can even improve to 350 million USD in favor of ICE expertise if Senegal also chooses to build new renewable vitality capacity throughout the subsequent decade.
Risk-managing potential gas infrastructure delays
The improvement of gasoline infrastructure is a posh and lengthy endeavour. Program delays aren’t unusual, causing gasoline supply disruptions that can have an enormous monetary impression on the operation of CCGT crops.
Nigeria is aware of something about that. Only final 12 months, important fuel supply points have caused shutdowns at some of the country’s largest fuel turbine energy crops. Because Gas turbines operate on a continuous combustion process, they require a constant supply of fuel and a secure dispatched load to generate consistent power output. If the availability is disrupted, shutdowns occur, placing a great pressure on the overall system. ICE-Gas plants then again, are designed to adjust their operational profile over time and increase system flexibility. Because of their versatile operating profile, they had been capable of keep a a lot greater degree of availability
The research took a deep dive to analyse the monetary influence of two years delay in the gas infrastructure program. It demonstrates that if the country decides to invest into gasoline engines, the price of fuel delay would be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in extra cost.
Whichever method you look at it, new ICE-Gas era capacity will decrease the total price of electrical energy in Senegal in all potential situations. If Senegal is to fulfill electrical energy demand growth in a cost-optimal way, no much less than 300 MW of new ICE-Gas capacity might be required by 2026.
