Hydropower is clean energy. Water is a safe natural product, a free and renewable source of energy. Hydropower production does not generate any emissions or waste. This is why HKL favours hydropower.
Although the construction of hydropower plants requires the taming of rapids and the construction of artificial lakes, the usage costs of hydropower plants are small and the amount of electricity generated can be effectively adjusted. The service life of hydropower plants is long since the technology used is durable and the plants can operate for decades. Hydropower generation can also be easily increased by expanding the capacity of existing hydropower plants.
Helsingin Energia supplies us with electricity generated with certified Finnish hydropower.
The electricity used in HKL’s transport operations is produced with Nordic hydro and wind power. We also use electricity generated using renewable energy sources in our premises.
The carbon dioxide emissions of wind and hydropower are zero.
