SENS: underground pumped hydro development at Pyhäsalmi mine, Pyhäjärvi
Etha supports SENS as project development consultant for underground pumped hydro storage at the decommissioned Pyhäsalmi mine.

The challenge

Etha's work covers a broad range of project development and technical consulting activities, including technical planning and engineering support, coordination with suppliers and authorities, and support related to the permits and approvals required to advance the project.
