For a long time, the wind turbine pitch system has relied on hydraulic or lead-acid battery systems for pitch control, but both have their own problems. The hydraulic system is very complex and requires a lot of maintenance, let alone difficulty in troubleshooting when problems occur. Lead acid batteries also require maintenance throughout their entire lifecycle, resulting in costly downtime.

Compared to these, energy based supercapacitors have multiple advantages: they require almost no maintenance over a lifespan of 15+years, and their reaction time is measured in milliseconds. Energy type supercapacitors greatly reduce the risk of incidental damage, while reducing maintenance costs and improving reliability.

Meanwhile, due to the long service life and minimal maintenance of energy type supercapacitors, they result in extremely low operating costs
