Senegal faces key know-how choices in its seek for the optimal gas-to-power strategy

Senegal’s domestic fuel reserves might be primarily used to provide electrical energy. Authorities anticipate that home fuel infrastructure tasks will come on-line between 2025 and 2026, offered there is no delay. The monetization of these significant power 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 research that analyse the financial impact of the various gas-to-power methods available to Senegal. Two very totally different applied sciences are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gasoline generators (CCGT) and Gas engines (ICE).
These research have revealed very vital system cost differences between the two primary gas-to-power technologies the nation is currently contemplating. Contrary to prevailing beliefs, gasoline engines are actually much better suited than mixed cycle fuel generators to harness energy from Senegal’s new gas assets cost-effectively, the examine reveals. Total value differences between the two applied sciences may attain as a lot as 480 million USD until 2035 relying on eventualities.
Two competing and really different technologies
The state-of-the-art power combine fashions developed by Wärtsilä, which builds customised energy eventualities to identify the price optimal approach to deliver new technology capacity for a particular country, reveals that ICE and CCGT technologies present significant cost differences for the gas-to-power newbuild program operating to 2035.
Although these two technologies are equally confirmed and dependable, they are very different by method of the profiles during which they can function. CCGT is a expertise that has been developed for the interconnected European electricity markets, the place it can operate at 90% load issue at all times. On the opposite hand, flexible ICE technology can function efficiently in all operating profiles, and seamlessly adapt itself to some other generation applied sciences that will make up the country’s power mix.
In particular our examine reveals that when operating in an electricity community of limited measurement corresponding to Senegal’s 1GW national grid, counting on CCGTs to significantly broaden the community capability can be extremely expensive in all potential situations.
เกจวัดแรงดันpressuregauge between the applied sciences are explained by a quantity of factors. First of all, sizzling climates negatively impact the output of fuel turbines greater than it does that of gasoline engines.
Secondly, due to Senegal’s anticipated entry to low cost home gas, the operating costs turn into much less impactful than the funding prices. In other words, as a result of low gasoline prices lower operating costs, it’s financially sound for the nation to rely on ICE energy plants, which are cheaper to build.
Technology modularity also performs a key function. Senegal is anticipated to require an extra 60-80 MW of technology capacity annually to have the flexibility to meet the increasing demand. This is much lower than the capability of typical CCGTs vegetation which averages 300-400 MW that have to be built in one go, resulting in unnecessary expenditure. Engine energy crops, on the opposite hand, are modular, which suggests they can be built exactly as and when the nation needs them, and further prolonged when required.
The numbers at play are vital. The model shows that If Senegal chooses to favour CCGT vegetation on the expense of ICE-gas, it will result in as a lot as 240 million dollars of additional price for the system by 2035. The cost distinction between the applied sciences can even enhance to 350 million USD in favor of ICE technology if Senegal also chooses to build new renewable energy capability throughout the subsequent decade.
Risk-managing potential fuel infrastructure delays
The development of gasoline infrastructure is a fancy and prolonged endeavour. Program delays usually are not uncommon, inflicting gas supply disruptions that will have an enormous monetary impression on the operation of CCGT crops.
Nigeria is aware of something about that. Only last 12 months, significant gas provide points have brought on shutdowns at a number of the country’s largest gasoline turbine energy crops. Because Gas turbines function on a steady combustion course of, they require a relentless supply of fuel and a stable dispatched load to generate consistent power output. If the provision is disrupted, shutdowns occur, placing an excellent pressure on the general system. ICE-Gas plants then again, are designed to regulate their operational profile over time and increase system flexibility. Because of their versatile operating profile, they have been able to maintain a a lot greater level of availability
The research took a deep dive to analyse the financial impression of two years delay in the fuel infrastructure program. It demonstrates that if the nation decides to invest into fuel engines, the value of gasoline delay can be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in additional cost.
Whichever method you have a glance at it, new ICE-Gas generation capacity will decrease the entire price of electricity in Senegal in all potential situations. If Senegal is to meet electrical energy demand growth in a cost-optimal method, at least 300 MW of recent ICE-Gas capacity shall be required by 2026.
