We achieve 99.99% availability in our energy networks, making them among the most reliable in the world. The supply reliability in 2021 remained unchanged at this extremely high level. However, it is becoming increasingly difficult to connect customers on time. Although we have devoted more effort to grid expansion projects and introducing smart solutions, bottlenecks continue to occur because demand is growing at a rate that outstrips our physical capabilities.
