Senegal faces key technology decisions in its search for the optimum gas-to-power strategy

Senegal’s home gas reserves will be primarily used to provide electricity. Authorities expect that home gasoline infrastructure projects will come on-line between 2025 and 2026, supplied there isn’t a delay. The monetization of these important power assets is on the foundation of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä carried out in-depth research that analyse the financial influence of the assorted gas-to-power strategies obtainable to Senegal. Two very totally different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These research have revealed very vital system price variations between the two main gas-to-power technologies the nation is presently contemplating. Contrary to prevailing beliefs, gasoline engines are actually much better suited than combined cycle gas turbines to harness energy from Senegal’s new fuel sources cost-effectively, the research reveals. Total value variations between the 2 technologies may reach as a lot as 480 million USD till 2035 relying on situations.
Two competing and very totally different technologies
The state-of-the-art power combine models developed by Wärtsilä, which builds customised energy situations to establish the fee optimal method to deliver new technology capability for a particular nation, reveals that ICE and CCGT applied sciences present vital value differences for the gas-to-power newbuild program running to 2035.
Although these two applied sciences are equally proven and dependable, they’re very different when it comes to the profiles during which they’ll function. CCGT is a expertise that has been developed for the interconnected European electricity markets, the place it could operate at 90% load factor at all times. On the other hand, versatile ICE expertise can function efficiently in all working profiles, and seamlessly adapt itself to some other technology applied sciences that may make up the country’s power mix.
In explicit our research reveals that when operating in an electrical energy network of restricted dimension such as Senegal’s 1GW national grid, relying on CCGTs to considerably increase the network capability could be extremely costly in all possible scenarios.
Cost variations between the applied sciences are defined by a number of factors. First of all, scorching climates negatively impression the output of gasoline turbines more than it does that of gasoline engines.
Secondly, thanks to Senegal’s anticipated access to cheap domestic gasoline, the operating prices turn out to be much less impactful than the funding costs. In other words, as a outcome of low gasoline prices lower working prices, it is financially sound for the country to rely on ICE energy crops, which are inexpensive to construct.
Technology modularity also plays a key role. Senegal is expected to require an extra 60-80 MW of technology capability each year to find a way to meet the growing demand. This is way decrease than the capability of typical CCGTs plants which averages 300-400 MW that have to be inbuilt one go, resulting in unnecessary expenditure. Engine energy plants, then again, are modular, which suggests they can be built precisely as and when the nation needs them, and additional extended when required.
The numbers at play are vital. The model shows that If Senegal chooses to favour CCGT vegetation at the expense of ICE-gas, it will result in as much as 240 million dollars of additional price for the system by 2035. The value difference between the technologies can even increase to 350 million USD in favor of ICE know-how if Senegal additionally chooses to construct new renewable vitality capability throughout the subsequent decade.
Risk-managing potential gasoline infrastructure delays
The development of gasoline infrastructure is a complex and prolonged endeavour. Program delays aren’t unusual, causing gas supply disruptions that will have a huge financial impression on the operation of CCGT vegetation.
เกจวัดน้ำยาแอร์refco knows one thing about that. Only final 12 months, significant gasoline supply issues have triggered shutdowns at a few of the country’s largest gas turbine energy plants. Because Gas turbines function on a continuous combustion course of, they require a relentless provide of fuel and a stable dispatched load to generate constant power output. If the provision is disrupted, shutdowns occur, placing an excellent pressure on the overall system. ICE-Gas crops however, are designed to adjust their operational profile over time and increase system flexibility. Because of their versatile working profile, they were able to preserve a a lot greater level 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 nation decides to take a position into fuel engines, the price 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 way you look at it, new ICE-Gas technology capability will reduce the total value of electrical energy in Senegal in all potential eventualities. If Senegal is to meet electrical energy demand growth in a cost-optimal way, a minimum of 300 MW of recent ICE-Gas capacity shall be required by 2026.
