Swiss Hydropower Reserves Declined More Than Average Last Week

Swiss hydroelectric reserves fell more than average last week, slowing the reduction of water used to generate power in the Alpine country.

Reservoir levels slid 3.7 percentage points to 70.7 percent full in the week through Nov. 29, the Bern-based Swiss Federal Energy Office said today in an e-mailed statement. The average weekly seasonal drop is 3.1 percentage points, according to data kept since 1997.

Water levels in Switzerland are 2.9 percentage points below the average of the past 13 years, the data show. Switzerland relies on hydropower for more than half its annual electricity consumption of about 55 terawatt-hours. Water supplies typically fall from October to April during the winter season. They are replenished from May to September by rain and melting snow.
