Energy giant SSE said its renewable assets produced 32% less electricity than expected between April 1 and September 22 thanks to historically dry, low wind conditions. This equates to 11% of his production target for the entire year.
“This deficit was caused by adverse weather conditions during the summer, which was one of the least windy in most of the UK and Ireland and one of the driest of the watersheds of ESS over the past seventy years, “said Perth, Scotland. the company said in a statement Wednesday.
Weak wind generation in the summer contributed to the European energy crisis, which has pushed electricity prices to record levels in recent days. Other factors include a colder-than-expected winter last year, production cuts during the pandemic, low imports from Russia, high carbon prices and growing demand from Asia for liquefied natural gas .
SSE is not the first renewable energy producer to warn of the financial impacts of low wind speed in summer.
In August, German utility RWE announced “much lower” wind energy volumes in its Northern and Central European portfolio for the first half of 2021.
Danish energy company Orsted made similar comments, saying “revenues from our operating offshore and onshore wind farms were DKK 0.3 billion lower in the same period last year.”
“The increase in the production capacity of the new wind farms in operation has been more than offset by significantly lower wind speeds across our portfolio,” the company said in August, while reiterating that it expects to achieve financial goals for the entire year.
Specifically, Orsted said that during the second quarter, the wind speed averaged 7.8 meters per second, which was “significantly lower” than normal speeds of 8.6 meters per second.
However, the management of SSE stressed Wednesday that these operational problems are “limited in time”. Management noted that performance in recent months has also been affected by hedging requirements in volatile markets.
Despite the summer slowdown, SSE said it “remains confident” in achieving its financial goals for the full year. The company also announced an expansion into the Japanese offshore wind market.
