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

Senegal’s domestic gasoline reserves might be primarily used to produce electrical energy. Authorities count on that home fuel infrastructure projects will come online between 2025 and 2026, provided there is not any delay. The monetization of these significant vitality sources is at the foundation of the government’s new gas-to-power ambitions.
In this context, the global expertise group Wärtsilä performed in-depth research that analyse the financial influence of the various gas-to-power strategies out there to Senegal. Two very 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 vital system price differences between the two major gas-to-power applied sciences the country is at present considering. Contrary to prevailing beliefs, gasoline engines are actually much better suited than mixed cycle gas generators to harness power from Senegal’s new gasoline assets cost-effectively, the research reveals. Total value variations between the 2 applied sciences might reach as much as 480 million USD till 2035 relying on scenarios.
Two competing and very totally different technologies
The state-of-the-art power mix models developed by Wärtsilä, which builds customised vitality eventualities to identify the cost optimal approach to ship new era capacity for a selected country, exhibits that ICE and CCGT technologies current important value differences for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally confirmed and dependable, they’re very completely different by way of the profiles in which they can operate. CCGT is a know-how that has been developed for the interconnected European electricity markets, where it can operate at 90% load factor always. On the other hand, flexible ICE know-how can operate effectively in all operating profiles, and seamlessly adapt itself to some other technology applied sciences that will make up the country’s energy mix.
In specific our examine reveals that when operating in an electricity network of restricted size similar to Senegal’s 1GW nationwide grid, relying on CCGTs to significantly broaden the community capability can be extraordinarily pricey in all possible eventualities.
Cost variations between the technologies are defined by a number of factors. First of all, hot climates negatively impact the output of fuel turbines greater than it does that of fuel engines.
Secondly, due to Senegal’s anticipated entry to cheap domestic gas, the working prices become much less impactful than the investment costs. In other words, as a result of low gasoline prices decrease working prices, it is financially sound for the nation to rely on ICE energy crops, that are inexpensive to build.
Technology modularity also plays a key position. Senegal is anticipated to require an additional 60-80 MW of technology capacity annually to have the flexibility to meet the growing demand. เครื่องมือใช้วัดความดัน is far lower than the capacity of typical CCGTs crops which averages 300-400 MW that should be inbuilt one go, leading to unnecessary expenditure. Engine power plants, on the other hand, are modular, which means they are often built precisely as and when the country wants them, and additional prolonged when required.
The numbers at play are significant. The model exhibits that If Senegal chooses to favour CCGT crops at the expense of ICE-gas, it’s going to lead to as much as 240 million dollars of extra cost for the system by 2035. The value distinction between the technologies may even increase to 350 million USD in favor of ICE expertise if Senegal additionally chooses to build new renewable power capability inside the next decade.
Risk-managing potential gasoline infrastructure delays
The growth of fuel infrastructure is a posh and prolonged endeavour. Program delays aren’t uncommon, causing gasoline supply disruptions that can have an enormous financial impression on the operation of CCGT plants.
Nigeria is aware of something about that. Only final year, vital gasoline provide points have brought on shutdowns at some of the country’s largest fuel turbine energy vegetation. Because Gas generators operate on a continuous combustion process, they require a relentless supply of gas and a steady dispatched load to generate consistent energy output. If the supply is disrupted, shutdowns occur, placing a great pressure on the general system. ICE-Gas crops however, are designed to regulate their operational profile over time and improve system flexibility. Because of their flexible working profile, they were able to keep a a lot greater stage of availability
The study took a deep dive to analyse the financial influence of two years delay within the gasoline infrastructure program. It demonstrates that if the country decides to invest into gasoline engines, the value of gas delay can be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in extra cost.
Whichever way you take a glance at it, new ICE-Gas technology capability will reduce the entire value of electrical energy in Senegal in all potential situations. If Senegal is to meet electricity demand development in a cost-optimal method, a minimum of 300 MW of latest ICE-Gas capability shall be required by 2026.
