Senegal’s domestic gasoline reserves might be primarily used to supply electricity. Authorities count on that home gasoline infrastructure tasks will come on-line between 2025 and 2026, supplied there is no delay. The monetization of those significant vitality resources is on the basis of the government’s new gas-to-power ambitions.
In this context, the worldwide technology group Wärtsilä conducted in-depth studies that analyse the financial impression of the various gas-to-power strategies out there to Senegal. Two very different applied sciences are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gasoline turbines (CCGT) and Gas engines (ICE).
These research have revealed very significant system price differences between the 2 major gas-to-power technologies the country is at present considering. Contrary to prevailing beliefs, fuel engines are actually much better suited than mixed cycle gas generators to harness power from Senegal’s new fuel resources cost-effectively, the research reveals. Total value differences between the 2 technologies could reach as much as 480 million USD until 2035 relying on scenarios.
Two competing and really completely different applied sciences
The state-of-the-art vitality combine models developed by Wärtsilä, which builds customised vitality scenarios to identify the fee optimum approach to ship new generation capability for a specific nation, reveals that ICE and CCGT technologies current vital value differences for the gas-to-power newbuild program working to 2035.
Although these two technologies are equally confirmed and reliable, they are very different by method of the profiles in 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 pressure gauge ไฮ ด รอ ลิ ค , versatile ICE know-how can operate effectively in all operating profiles, and seamlessly adapt itself to another era applied sciences that will make up the country’s energy mix.
In explicit our study reveals that when working in an electrical energy network of restricted dimension such as Senegal’s 1GW national grid, counting on CCGTs to considerably increase the community capability can be extremely expensive in all attainable eventualities.
Cost differences between the technologies are defined by a selection of components. First of all, scorching climates negatively impression the output of gasoline turbines more than it does that of gasoline engines.
Secondly, due to Senegal’s anticipated entry to cheap domestic fuel, the working prices turn into less impactful than the funding costs. In different words, as a result of low gas prices lower working costs, it’s financially sound for the country to rely on ICE power crops, which are inexpensive to build.
Technology modularity also plays a key position. Senegal is expected to require an extra 60-80 MW of generation capability annually to have the power to meet the growing demand. This is far lower than the capability of typical CCGTs crops which averages 300-400 MW that must be built in one go, resulting in unnecessary expenditure. Engine power plants, on the other hand, are modular, which suggests they can be built exactly as and when the nation needs them, and further extended when required.
The numbers at play are important. The model reveals 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 price for the system by 2035. The value distinction between the technologies can even increase to 350 million USD in favor of ICE technology if Senegal additionally chooses to build new renewable power capacity inside the subsequent decade.
Risk-managing potential gasoline infrastructure delays
The development of fuel infrastructure is a posh and prolonged endeavour. Program delays aren’t uncommon, inflicting gasoline supply disruptions that can have a huge monetary impact on the operation of CCGT vegetation.
Nigeria is conscious of one thing about that. Only last 12 months, important gas supply points have brought on shutdowns at a variety of the country’s largest fuel turbine power plants. Because Gas turbines operate on a steady combustion course of, they require a continuing supply of fuel and a stable dispatched load to generate constant energy output. If the provision is disrupted, shutdowns happen, placing a fantastic pressure on the general system. ICE-Gas crops on the other hand, are designed to adjust their operational profile over time and improve system flexibility. Because of their versatile operating profile, they were able to keep a much greater level of availability
The research took a deep dive to analyse the financial impression of two years delay within the fuel infrastructure program. It demonstrates that if the country decides to speculate into gasoline engines, the value of gasoline delay would be 550 million dollars, whereas a system dominated by CCGTs would result in a staggering 770 million dollars in further cost.
Whichever method you have a look at it, new ICE-Gas generation capability will minimize the entire cost of electrical energy in Senegal in all attainable eventualities. If Senegal is to fulfill electricity demand progress in a cost-optimal method, a minimal of 300 MW of new ICE-Gas capacity might be required by 2026.
