Perth-based utility SSE said it is on course to deliver a 5% increase in profits for the current financial year.
The company, which will spend £1.5 billion on capital projects by the year end, expects a full year shareholder dividend at least 2% above RPI inflation at around 84p per share.
The expected increase in profits comes despite SSE suffering a marginal reduction in electricity and gas customers 9.55m to 9.46m in the nine months to December 31.
SSE said total electricity output from its gas powered assets had dropped significantly due largely to planned work at its Keadby and Medway stations, while its green energy portfolio including hydro, on and offshore windfarms and biomass saw output fall slightly from 5.3TWh to 5.2TWh.
The company said it passed a renewables milestone on December 28 when generating capacity from renewable sources exceeded 2,000MW.
Chief executive Ian Marchant, who is to leave SSE this summer, said: “This financial year has been characterised by continuing economic uncertainty and challenging energy market conditions which have affected energy customers and electricity producers alike.
“SSE’s balanced model of market-based and economically-regulated businesses and strategy of focusing on operations and investments in these businesses is again proving to be robust.”
