Kemijoki advances pumped storage hydropower projects in Finland

Recent work|February 10, 2025

Roschier is advising Kemijoki in the development and permitting of pumped storage hydropower plants.

Kemijoki Oy plans to build several 200–600 MW pumped storage plants to be built in the Kemijoki water area. Depending on the scale of the investment, this could increase the regulating capacity of hydropower in Finland by up to 4,000 MW. The potential investment may range from 2 to 3 billion euros.

The regulating capability of hydropower is becoming increasingly important for energy self-sufficiency and security of supply as Finland shifts from fossil fuels to renewable energy sources. The Finnish energy system is rapidly changing due to increasing intermittent wind and solar power production. Additionally, the electrification of society and future industrial investments are expected to increase electricity demand. Thus, there is a growing need for regulating power to balance the energy system and for large-scale electricity storages.

Kemijoki is the most significant producer of hydropower and regulating power in Finland.

The core advisory team comprises Matias Wallgren, Sanna-Mari Seppälä, Sofia Lyyra, and Sanni-Sofia Marsala.
