Spain’s hydroelectricity generation potential recovers in week 18

03 May 2012 16:58:01 | edem

Spain had 11.03TWh of hydroelectric capacity available in the week to 1 May - or 49% of its maximum 22.33TWh capacity - figures published on Thursday by the country's environment minister show.

Stocks increased by 1.6 percentage points week on week from an available generation of 10.69TWh last week - the largest week-on-week increase in 2012.

The rise came as aggregate rainfall across Spain on 23-29 April totalled 22.3mm, which is 70% above average, the ministry said.

Hydroelectric generation potential has been low recently because of dry weather, and has gradually moved away from the five-year average.

Fullness in week 18 stands 11.9 percentage points below the five-year average of 61.27TWh, and 23.3 percentage points below the figures recorded in the same week in 2011.

As a result of low reservoir levels, Spanish hydroelectric output since 1 January has totalled 5.6TWh - 60% less than the same period last year, according to the ministry.

The country's hydroelectric installations were forecast to generate 10.4% of Thursday's total net generation of 719GWh, according to transmission system operator REE - up from 9.2% on Tuesday last week. SM
