Industry Trends and Drivers:
- Growth in automotive industry:
Globally, the automotive industry has expanded and this is due to the fact that the flow of cars is escalating in developed as well as in the emerging markets. The lights, infotainment, conditioning and air supply, and advanced driver assistance systems (ADAS) electrical systems in vehicles require an alternator. The more the vehicles, the more the demand for alternators due their importance in the operation of cars. Contemporary automobiles are relying on electrical systems to drive almost all of the possible functionalities. Many of these include steering control, voice control and identification, temperature regulation, autopilot and self-driving and in electric cars hybrid form and full electric vehicles (FEVs). All these systems demand higher power and hence alternators are used to produce as well as supply electricity.
- Industrial and power generation sectors:
Alternators are vital in power plants including thermal, nuclear, hydro and renewable; as they are used in generating electricity. In these facilities, steam, water or wind generated turbines are coupled with alternators that change mechanical energy into electrical power. In the same way, industrial purposes such as factories and power plants need temporary power during blackouts etc. Alternators are crucial components of diesel and gas generators which are important source of back up electric power. Increasing industrialization and the availability and subsequent reliance on UPS systems in industries and critical infrastructure are to be thanked for triggering the need for alternators.
- Rising reliance on renewable energy:
Robust renewable energies such as wind, solar, and hydropower make for renewable energies, are behind the alternators market as these power generation systems need to be efficient. wind mills, solar power farms, Hydro electric power stations uses alternators to generate electricity from mechanical energy. Furthermore, power storage facilities like batteries need alternators for charging, more so in the applications in hybrid and off-grid facilities. Due to the gradual adoption of clean energy and sustainable energy sources on the global level, there is a demand as well as opportunity for high performance, efficient alternators that can be integrated into the renewable energy systems to provide stability and reliability in areas of different sectors.
