Switzerland energy projects face cost and feasibility concerns

Internal reports from the Swiss Federal Office of Energy have revealed significant discrepancies regarding the feasibility and costs of major energy infrastructure projects. An analysis by a technical group appointed by Federal Councillor Albert Rösti indicates that the energy industry may have overestimated the potential of several hydropower expansion projects.

The report highlights that over one-third of the planned dam and expansion projects cannot be built as originally envisioned. Specific issues cited include a lack of preliminary investigations for several projects, tripled cost estimates, and delays due to concession renewals. Consequently, the projected winter electricity yield from these initiatives has been revised downward from 2,031 GWh to 1,248 GWh.

Additionally, controversy is growing within the Federal Office of Energy regarding the projected costs of new nuclear power plants. Tensions have emerged between Federal Councillor Rösti and the office's leadership, specifically regarding how cost discussions and data disclosures are being managed.
