SSE experienced lower than expected output from renewables in the first quarter of the 2019-20 financial, but this is not expected to impact the company’s business performance for the year.
The company said that the weather in the UK and Ireland in the period meant output was about 400 gigawatt hours (GWh), or 20%, lower than expected.
Total electricity generation from clean power was 1794GWh in the three months to 30 June 2019, up from 1562GWh in the same period last year.
The increased output was down to new wind farm capacity since June 2018, the company said.
Onshore wind generation was 856GWh, up from 766GWh, while offshore generation rose to 482GWh, from 213GWh in 2018.
SSE chief executive Alistair Phillips-Davies said: “The early months of our financial year have brought some short-term challenges and some encouraging longer-term developments, but the key months of our financial year lie ahead.
“I am confident we will make good progress in delivering against our strategic priorities, including the five- year dividend plan out to 2023.
“The fact the UK has become the first major economy to legislate for net zero emissions by 2050 is a key development in the fight against climate change and reinforces SSE’s strategic focus on regulated electricity networks and renewable energy, and our commitment to creating value through the low carbon transition.”
