Global Excitation Systems Market Dynamics

The key market dynamics that are shaping the excitation systems market include

Key Market Drivers

• Increasing Global Electricity Demand The rising global need for power is a major driver of the excitation systems market. According to the International Energy Agency (IEA), global electricity demand is expected to increase by 2.1% each year until 2040. Despite the COVID-19 epidemic, worldwide power demand declined by just around 1% in 2020 and is likely to recoup and rise in the years ahead. This growing demand necessitates the construction and updating of power-producing facilities, resulting in the necessity for sophisticated excitation systems.
• Growing Renewable Energy Sector The fast expansion of renewable energy sources, particularly wind and solar power, is driving up demand for excitation systems. The International Renewable Energy Agency (IRENA) says that renewable energy capacity additions in 2020 increased by 45% to 280 GW, the greatest year-on-year rise since 1999. This growth in renewable energy installations is boosting the demand for excitation systems to ensure stable power generation and grid integration.
• Aging Power Infrastructure in Developed CountriesMany wealthy countries are experiencing the challenge of aging electricity infrastructure that requires renovation and upgrades. According to the US Department of Energy, 70% of power transformers are over 25 years old, while 60% of circuit breakers are over 30 years old. This aging infrastructure is pushing investments in new and improved power plants, including modern excitation systems, to improve efficiency and reliability.

Key Challenges

• High Maintenance Requirements The high maintenance requirements of excitation systems are a key restriction on the market. If not adequately maintained, excitation systems cause unscheduled outages in power plants, disrupting operations and resulting in financial losses. This requirement for frequent maintenance discourages potential investors and limits market expansion, especially in locations with small operational budgets and inadequate maintenance resources.
• Rapid Technological Advancements The rapid growth of digital control system technology is another barrier. As digital excitation control technologies gain popularity, older excitation systems struggle to compete. This transition involves significant investment in research and development to stay up with developments, which is prohibitively expensive for smaller enterprises or those with limited resources, potentially leading to market consolidation as larger competitors dominate.
• Fluctuations in Energy Prices Energy price fluctuations have an impact on the market for excitation systems. Economic downturns or energy market volatility result in lower investments in power generation infrastructure, including excitation systems. When energy prices are low, utilities postpone or reduce upgrades or replacements of current systems, slowing market growth and innovation in excitation technology.

Key Trends

• Growing Integration of Digital Technologies The increasing incorporation of digital technology is a major trend in the excitation systems market. Digital excitation systems are becoming more popular due to their improved monitoring and control capabilities, which increase the reliability and efficiency of synchronous machines. These systems maximize performance through advanced algorithms and data analytics, allowing utilities to better manage power generation and distribution, especially in the face of variable renewable energy demands.
• Increasing Demand for Brushless Excitation Systems The rising need for brushless excitation systems is another development. These methods eliminate the need for slide rings and carbon brushes, resulting in lower maintenance and greater reliability. Brushless systems are gaining popularity as companies look to cut operational costs and downtime. Their efficiency in power transfer and decreased wear and tear contribute to their growing adoption, particularly in applications where maintenance access is challenging.
• Rise of Renewable Energy Sources The advent of renewable energy sources has a considerable impact on the excitation systems market. As the energy landscape evolves toward solar, wind, and hydroelectric power, the demand for dependable excitation systems to stabilize these intermittent energy sources grows. Excitation systems serve an important role in ensuring voltage stability and reactive power support, both of which are required for integrating renewable energy into existing power grids and promoting market growth.
