Senegal’s home gas reserves shall be primarily used to supply electrical energy. Authorities anticipate that domestic gasoline infrastructure projects will come on-line between 2025 and 2026, offered there isn’t a delay. The monetization of those vital power sources is on the basis of the government’s new gas-to-power ambitions.
In this context, the worldwide technology group Wärtsilä conducted in-depth research that analyse the financial impact of the varied gas-to-power methods available to Senegal. Two very totally 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 significant system price variations between the two major gas-to-power technologies the nation is presently considering. Contrary to prevailing beliefs, gas engines are actually significantly better suited than mixed cycle gasoline generators to harness energy from Senegal’s new gasoline resources cost-effectively, the study reveals. Total value differences between the 2 applied sciences might attain as much as 480 million USD till 2035 relying on scenarios.
Two competing and very different technologies
The state-of-the-art energy mix models developed by Wärtsilä, which builds customised vitality situations to identify the fee optimal method to ship new technology capacity for a particular country, exhibits that ICE and CCGT applied sciences current significant price differences for the gas-to-power newbuild program working to 2035.
Although these two technologies are equally confirmed and dependable, they are very different when it comes to the profiles in which they’ll function. CCGT is a know-how that has been developed for the interconnected European electrical energy markets, where it could operate at 90% load issue always. On the opposite hand, flexible ICE technology can function effectively in all working profiles, and seamlessly adapt itself to some other generation applied sciences that may make up the country’s power mix.
In specific our study reveals that when operating in an electrical energy network of limited measurement similar to Senegal’s 1GW nationwide grid, counting on CCGTs to considerably broaden the community capability can be extraordinarily pricey in all possible situations.
Cost differences between the technologies are explained by a variety of factors. First of all, hot climates negatively impact the output of fuel turbines greater than it does that of gas engines.
Secondly, thanks to Senegal’s anticipated entry to low cost home fuel, the working prices turn into much less impactful than the funding costs. In other words, as a end result of low gas prices decrease operating prices, it is financially sound for the country to depend on ICE energy crops, which are less expensive to construct.
Technology modularity additionally plays a key position. Senegal is expected to require an extra 60-80 MW of era capacity each year to have the ability to meet the growing demand. This is far lower than the capability of typical CCGTs vegetation which averages 300-400 MW that should be inbuilt one go, resulting in pointless expenditure. Engine power crops, however, are modular, which implies they are often constructed precisely as and when the country needs them, and further extended when required.
pressure gauge 0 10 bar ราคา at play are significant. The model exhibits that If Senegal chooses to favour CCGT vegetation at the expense of ICE-gas, it’s going to lead to as much as 240 million dollars of extra value for the system by 2035. The value difference between the technologies can even improve to 350 million USD in favor of ICE technology if Senegal also chooses to build new renewable power capability inside the subsequent decade.
Risk-managing potential gasoline infrastructure delays
The improvement of fuel infrastructure is a complex and prolonged endeavour. Program delays aren’t uncommon, causing fuel provide disruptions that may have a huge financial impact on the operation of CCGT vegetation.
Nigeria is aware of one thing about that. Only final yr, important fuel supply points have brought on shutdowns at a variety of the country’s largest gas turbine energy crops. Because Gas turbines operate on a continuous combustion process, they require a relentless provide of gas and a steady dispatched load to generate consistent energy output. If the availability is disrupted, shutdowns occur, placing a great pressure on the overall system. ICE-Gas crops however, are designed to adjust their operational profile over time and enhance system flexibility. Because of their flexible working profile, they had been able to maintain a a lot greater stage of availability
The study took a deep dive to analyse the monetary influence of two years delay within the gas infrastructure program. It demonstrates that if the country decides to take a position into gas 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 further price.
Whichever way you look at it, new ICE-Gas generation capacity will decrease the entire value of electrical energy in Senegal in all possible situations. If Senegal is to fulfill electricity demand growth in a cost-optimal method, a minimal of 300 MW of recent ICE-Gas capability might be required by 2026.
