Senegal’s domestic gasoline reserves shall be mainly used to supply electrical energy. Authorities count on that home gasoline infrastructure initiatives will come online between 2025 and 2026, offered there is not a delay. The monetization of these vital energy sources is on the basis of the government’s new gas-to-power ambitions.
In this context, the global technology group Wärtsilä performed in-depth studies that analyse the economic impression of the various gas-to-power strategies obtainable to Senegal. Two very completely different technologies are competing to satisfy the country’s gas-to-power ambitions: Combined-cycle gasoline turbines (CCGT) and Gas engines (ICE).
These studies have revealed very important system price variations between the 2 major gas-to-power applied sciences the nation is presently considering. Contrary to prevailing beliefs, fuel engines are in fact significantly better suited than mixed cycle gas turbines to harness energy from Senegal’s new gasoline resources cost-effectively, the study reveals. Total price variations between the 2 applied sciences may reach as much as 480 million USD till 2035 depending on eventualities.
เกจวัดแรงดันราคา competing and really different applied sciences
The state-of-the-art energy combine models developed by Wärtsilä, which builds customised energy situations to identify the fee optimal approach to deliver new era capability for a specific country, reveals that ICE and CCGT applied sciences current vital value variations for the gas-to-power newbuild program working to 2035.
Although these two technologies are equally proven and dependable, they are very totally different in phrases of the profiles by which they can function. CCGT is a expertise that has been developed for the interconnected European electricity markets, the place it could function at 90% load factor at all times. On the opposite hand, versatile ICE expertise can function efficiently in all operating profiles, and seamlessly adapt itself to some other technology applied sciences that can make up the country’s power mix.
In particular our examine reveals that when operating in an electrical energy network of limited dimension such as Senegal’s 1GW nationwide grid, counting on CCGTs to considerably increase the network capability can be extraordinarily expensive in all attainable situations.
เกจวัดแรงดันลม10bar between the applied sciences are explained by a quantity of components. First of all, scorching climates negatively impression the output of gas generators greater than it does that of fuel engines.
Secondly, due to Senegal’s anticipated entry to low cost domestic gas, the working costs turn into much less impactful than the investment costs. In different words, as a outcome of low fuel prices lower working prices, it is financially sound for the nation to depend on ICE power vegetation, which are cheaper to construct.
Technology modularity also performs a key role. Senegal is anticipated to require an additional 60-80 MW of technology capacity annually to have the power to meet the increasing demand. This is way decrease than the capability of typical CCGTs vegetation which averages 300-400 MW that have to be in-built one go, resulting in unnecessary expenditure. Engine energy crops, on the other hand, are modular, which suggests they are often constructed precisely as and when the nation needs them, and additional prolonged when required.
The numbers at play are important. The model exhibits that If Senegal chooses to favour CCGT plants on the expense of ICE-gas, it’s going to result in as much as 240 million dollars of additional cost for the system by 2035. The value distinction between the technologies may even increase to 350 million USD in favor of ICE expertise if Senegal also chooses to build new renewable power capability within the subsequent decade.
Risk-managing potential gas infrastructure delays
The growth of gas infrastructure is a posh and lengthy endeavour. Program delays aren’t uncommon, inflicting fuel supply disruptions that may have an enormous monetary influence on the operation of CCGT plants.
Nigeria is aware of one thing about that. Only final year, important fuel supply points have triggered shutdowns at a variety of the country’s largest gas turbine power vegetation. Because Gas turbines operate on a continuous combustion course of, they require a continuing provide of gas and a secure dispatched load to generate constant power output. If the supply is disrupted, shutdowns occur, putting a fantastic strain on the general system. ICE-Gas crops however, are designed to adjust their operational profile over time and enhance system flexibility. Because of their flexible operating profile, they have been in a place to maintain a much greater level of availability
The study took a deep dive to analyse the monetary impression of 2 years delay within the gasoline infrastructure program. It demonstrates that if the nation decides to invest into gasoline engines, the cost of gas delay can be 550 million dollars, whereas a system dominated by CCGTs would lead to a staggering 770 million dollars in extra value.
Whichever method you look at it, new ICE-Gas technology capacity will minimize the total price of electricity in Senegal in all potential situations. If Senegal is to meet electrical energy demand progress in a cost-optimal means, no much less than 300 MW of new ICE-Gas capacity might be required by 2026.
