Faster RE Deployment In West Africa Might Save Millions By 2030-Wärtsilä Study

  • A technique shift in favour of renewables will bring considerable economic advantages as power systems are broadened.

Speaking recently at the West Africa Energy Transition Forum in Dakar in the visibility of vital energy decision-makers, professionals from Wärtsilä shared understandings on the impact renewables will carry power system cost, flexibility, as well as stability in West Africa.

They offered the outcomes of their most current study which explores Senegal's ideal power system expansion. The study disclosed that speeding up the deployment of renewable resource beyond what is currently intended will certainly result in a shocking $700 countless financial savings up until 2035, largely because of the massive decrease in fuel costs that it will produce. Significant cost financial savings are also anticipated in various other West African countries that choose to concentrate investment on renewables, supported by flexible power generation.

Using power system modelling techniques, Wärtsilä aids worldwide energy authorities recognize as well as shape ideal energy techniques. The firm has actually acquired significant experience of African energy markets through the shipment over 200 power plants in 46 African countries, for a total of 7.6 GW of capacity.

" We held this online forum to address pushing questions encountering energy authorities in Senegal, Guinea, or Mauritania today, starting with the loved one share that renewable resource must have in their power mix. How much renewable resource should they build, exactly how quick as well as at what cost? How much flexible power capacity will be needed to ensure grid stability while accommodating a raising amount of recurring renewable power? Answering these questions is vital to notifying their energy techniques moving forward," explained Marc Thiriet, Director, Africa, Wärtsilä Energy.

Senegal's Power Expansion Plans: A Case in Point

Wärtsilä offered the searchings for of a study that analyzes the monetary and also ecological impacts of different renewable resource deployment degrees on Senegal's power system. Senegal's existing strategy was compared to a "High Renewables" strategy including the addition of some 2,100 MW of renewables by 2035. Both situations have actually been designed carefully with the powerful Plexos software to recognize one of the most optimal power mix for every scenario as well as contrast overall system costs.

The study reveals that the scenario including a better deployment of renewable energy in the power system will, by far, be one of the most budget-friendly and sustainable choice. Paired with energy storage space and flexible engine nuclear power plant to maintain a constant as well as stable power supply, a bigger share of renewable energy will certainly decrease carbon emissions by 30% by 2030 and also create total system cost savings of $700 million dollars by 2035. The fuel financial savings are the main factor in reducing the total cost of the system given that renewable energy will partially remove the need to be run thermal power plants at full load to please need.

" Our study shows very clearly that increasing low-priced renewable energy remains in Senegal's benefit, both financially and ecologically. We would certainly probably get to the very same outcomes, albeit of varying ranges, if we were to analyse Guinea, Ivory Coast, or Mauritania's power systems in similar deepness," claimed Kenneth Engblom, Vice President, Africa § Europe, Wärtsilä Energy.

" Rate alone is converting the globe to renewable resource", proceeded Joonatan Huhdanmäki, Market Development Manager at Wärtsilä, adding, "In 2022, solar energy was already the most affordable resource of new power generation in many countries of the globe, including in Africa. This is a global pattern that will continue to speed up. According to IEA, in order to reach net-zero by 2050 the share of renewable resource should reach 61% by 2030 as well as an astonishing 84% by 2040."

Recognizing the Balancing Needs of High Renewable Power Grids

Balancing power describes the capability of a power system to maintain a steady as well as dependable supply of electrical energy, by matching the electrical energy need with the available generation capacity in real-time.

Since renewable resource is intermittent, added balancing capacity is needed to supply sufficient flexibility to the power system as well as make certain grid stability. "The equation for grid stability is rather easy to recognize. Every megawatt of intermittent renewable capacity that is installed should be matched with equivalent levels of flexibility in the form of energy storage and also balancing nuclear power plant, to ensure that we can always match power supply and also need," explained Kenneth Engblom.

To stabilize the grid, drivers will certainly utilize two corresponding modern technologies: Flexible engine nuclear power plant, which can be rapidly increase or to reply to changes in electrical power supply, will be used whenever renewable capacity wants to satisfy need. Energy storage systems, on the other hand, will keep the excess electrical energy when sustainable generation goes beyond demand. Both will certainly collaborate to maintain the grid secure and secure.

The Path to Carbon-Free Power Systems in West Africa

The path to decarbonisation of the energy system is rather similar all over worldwide. The first step is to add the best mix of renewables, balancing nuclear power plant, as well as storage capacity, while phasing out inflexible power plants. The second action is to convert the flexible engine nuclear power plant running on gas to operate on sustainable fuels, at which stage the power system will certainly no longer need fossil fuels in all.

" Decarbonisation is completely possible with the present innovations we have, and in contrast to popular belief, it's not going to set you back more: it's mosting likely to cost less," concluded Marc Thiriet. "We have got wind, as well as solar modern technologies. We have storage innovations as well as flexible engine nuclear power plant for grid balancing. And we have sustainable fuels that we will make use of to run the balancing power plants when these fuels come to be much more extensively available."

Wärtsilä Energy's track record makes up 76 GW of nuclear power plant capacity as well as 110 energy storage space systems supplied to 180 countries worldwide.
