Senegal’s home gas reserves might be primarily used to provide electrical energy. Authorities anticipate that domestic gas infrastructure initiatives will come on-line between 2025 and 2026, offered there is not a delay. The monetization of those significant power assets is at the foundation of the government’s new gas-to-power ambitions.
In this context, the worldwide know-how group Wärtsilä performed in-depth studies that analyse the economic impact of the assorted gas-to-power strategies out there to Senegal. Two very completely different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gas turbines (CCGT) and Gas engines (ICE).
These studies have revealed very vital system cost variations between the 2 main gas-to-power technologies the nation is at present contemplating. Contrary to prevailing beliefs, gas engines are actually a lot better suited than mixed cycle gasoline generators to harness energy from Senegal’s new fuel resources cost-effectively, the examine reveals. Total value differences between the 2 technologies might reach as much as 480 million USD until 2035 relying on situations.
Two competing and really different applied sciences
The state-of-the-art energy mix fashions developed by Wärtsilä, which builds customised energy eventualities to identify the fee optimal approach to deliver new era capacity for a specific nation, exhibits that ICE and CCGT applied sciences present significant price variations for the gas-to-power newbuild program running to 2035.
Although these two technologies are equally proven and reliable, they’re very totally different when it comes to the profiles by which they will function. CCGT is a technology that has been developed for the interconnected European electricity markets, where it might possibly operate at 90% load factor at all times. On the opposite hand, versatile ICE know-how can operate effectively in all working profiles, and seamlessly adapt itself to another era applied sciences that will make up the country’s power combine.
In ราคาเกจวัดแรงดันลม reveals that when working in an electrical energy community of restricted dimension corresponding to Senegal’s 1GW nationwide grid, counting on CCGTs to significantly expand the network capacity can be extremely pricey in all possible scenarios.
Cost variations between the technologies are defined by numerous elements. First of all, hot climates negatively influence the output of gasoline turbines greater than it does that of gasoline engines.
Secondly, thanks to Senegal’s anticipated entry to low-cost domestic gas, the working prices turn out to be much less impactful than the investment costs. In different words, as a result of low gasoline costs lower operating costs, it is financially sound for the nation to rely on ICE energy plants, which are less expensive to build.
Technology modularity also performs a key role. Senegal is anticipated to require an extra 60-80 MW of technology capacity each year to have the ability to meet the increasing demand. This is far 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, then again, are modular, which implies they are often constructed 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 vegetation at the expense of ICE-gas, it’ll lead to as much as 240 million dollars of extra price for the system by 2035. The price difference between the applied sciences may even increase to 350 million USD in favor of ICE technology if Senegal also chooses to build new renewable energy capability inside the subsequent decade.
Risk-managing potential gasoline infrastructure delays
The improvement of fuel infrastructure is a fancy and prolonged endeavour. Program delays usually are not unusual, causing gas supply disruptions that can have an enormous financial impression on the operation of CCGT plants.
Nigeria knows one thing about that. Only final yr, important gasoline provide issues have brought on shutdowns at a few of the country’s largest fuel turbine energy vegetation. Because Gas turbines function on a continuous combustion process, they require a constant provide of gas and a stable dispatched load to generate constant energy output. If the provision is disrupted, shutdowns occur, placing a great strain on the general system. ICE-Gas crops on the opposite hand, are designed to adjust their operational profile over time and improve system flexibility. Because of their versatile operating profile, they have been able to maintain a a lot larger stage of availability
The study took a deep dive to analyse the monetary impact of 2 years delay within the gasoline infrastructure program. It demonstrates that if the nation decides to speculate into gas engines, the price of fuel delay could be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further cost.
Whichever way you look at it, new ICE-Gas technology capability will decrease the whole price of electrical energy in Senegal in all possible situations. If Senegal is to fulfill electricity demand progress in a cost-optimal means, at least 300 MW of recent ICE-Gas capacity might be required by 2026.
