Senegal’s domestic gasoline reserves might be mainly used to provide electricity. Authorities expect that home gas infrastructure initiatives will come online between 2025 and 2026, offered there is no delay. The monetization of these vital energy assets is at the basis of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä conducted in-depth research that analyse the financial impression of the various gas-to-power strategies available to Senegal. เกจวัดแรงดันไฟฟ้า are competing to meet the country’s gas-to-power ambitions: Combined-cycle fuel generators (CCGT) and Gas engines (ICE).
These research have revealed very vital system value differences between the two major gas-to-power technologies the country is presently considering. Contrary to prevailing beliefs, gasoline engines are actually significantly better suited than combined cycle gas turbines to harness energy from Senegal’s new gasoline assets cost-effectively, the examine reveals. Total value variations between the two technologies may attain as a lot as 480 million USD until 2035 depending on scenarios.
Two competing and really different technologies
The state-of-the-art power mix models developed by Wärtsilä, which builds customised power situations to determine the price optimal approach to deliver new technology capacity for a selected country, exhibits that ICE and CCGT applied sciences present vital cost differences for the gas-to-power newbuild program working to 2035.
Although these two applied sciences are equally proven and dependable, they’re very totally different when it comes to the profiles by which they’ll function. CCGT is a technology that has been developed for the interconnected European electrical energy markets, where it could possibly function at 90% load factor at all times. On the opposite hand, flexible ICE know-how can function efficiently in all working profiles, and seamlessly adapt itself to another technology technologies that can make up the country’s energy combine.
In particular our study reveals that when operating in an electricity community of restricted dimension similar to Senegal’s 1GW nationwide grid, counting on CCGTs to considerably increase the network capability can be extremely costly in all potential scenarios.
Cost variations between the technologies are explained by a variety of elements. First of all, sizzling climates negatively impact the output of gas turbines greater than it does that of fuel engines.
Secondly, because of Senegal’s anticipated entry to low cost home gasoline, the working prices become less impactful than the funding costs. In different phrases, because low gas prices lower operating costs, it is financially sound for the nation to depend on ICE energy plants, that are inexpensive to construct.
Technology modularity additionally plays a key position. Senegal is expected to require an extra 60-80 MW of era capability annually to have the flexibility to meet the growing demand. This is much lower than the capability of typical CCGTs plants which averages 300-400 MW that have to be built in one go, resulting in pointless expenditure. Engine energy plants, on the other hand, are modular, which implies they can be constructed exactly as and when the country needs them, and additional prolonged when required.
The numbers at play are vital. The mannequin shows that If Senegal chooses to favour CCGT crops at the expense of ICE-gas, it’ll result in as much as 240 million dollars of additional value for the system by 2035. The price distinction between the applied sciences can even enhance to 350 million USD in favor of ICE know-how if Senegal also chooses to build new renewable energy capacity throughout the next decade.
Risk-managing potential gas infrastructure delays
The development of gasoline infrastructure is a complex and prolonged endeavour. Program delays are not uncommon, inflicting fuel supply disruptions that will have a huge monetary impact on the operation of CCGT vegetation.
Nigeria is aware of one thing about that. Only last year, vital gasoline supply issues have brought on shutdowns at a number of the country’s largest gas turbine energy plants. Because Gas turbines operate on a continuous combustion process, they require a constant supply of gas and a stable dispatched load to generate constant energy output. If the provision is disrupted, shutdowns occur, placing a great pressure on the overall system. ICE-Gas plants then again, are designed to adjust their operational profile over time and enhance system flexibility. Because of their flexible working profile, they had been capable of keep a a lot greater degree 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 invest into gas engines, the cost of gasoline delay could be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in extra price.
Whichever method you look at it, new ICE-Gas generation capability will reduce the whole price of electrical energy in Senegal in all attainable situations. If Senegal is to meet electrical energy demand growth in a cost-optimal means, no much less than 300 MW of new ICE-Gas capacity shall be required by 2026.
