COVID-19 IMPACT

Excitation System Industry Had a Negative Effect Due to Project Delays during the COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The new power plants' building and revamping of the existing generators were all postponed because of the travel bans, lack of workers, and financial uncertainties. Consequently, there was a delay in installation and a gradual introduction of the new excitation systems worldwide. The global lockdown and restrictions caused a huge disturbance in the supply chain of the electronic components, semiconductors, and other raw materials which are all vital for the manufacturing of the excitation system. The delayed shipments with longer lead times had a negative impact on the production schedules and temporarily slowed down market growth.

The sudden changes in electricity demand during the COVID-19 crisis revealed the critical role of power systems' stability. The power companies and the industrial plants got the message that reliable excitation systems are a must for generator voltage and reactive power control. Thus, the investment in modern excitation technologies that can cope with the support of variable load operations was the step forward.
