With this, the company has tested the electricity generation equipment at the scheme, in advance of it being formally commissioned and handed over to Scottish and Southern Energy’s (SSE) generation operations division, which is expected to take place later in December 2008.

Glendoe is reported to be the first large-scale conventional hydro electric station to be built in the UK since 1957, when the 75MW Errochty station in Perthshire was opened, claims the company.

Ian Marchant, CEO of SSE, said: “I have been pleased to see the progress at Glendoe and to see this stage in the commissioning of the scheme being reached. There was a risk that Scotland’s hydro electric schemes would be left behind in the search for newer forms of green energy production. Since then, we have invested over GBP330 million in refurbishing and developing hydro electric schemes in Scotland.”

Scottish and Southern Energy’s core purpose is to provide the energy people need in a sustainable way and the strategy is to deliver sustained growth in the dividend payable to shareholders through the operation of, and investment in, a balanced range of regulated and non-regulated energy and utility businesses.
