Plans for a new power station north of Lerwick, that could run on natural gas have been submitted to the Scottish government.
The company is planning a 120 megawatt power station to be dug out of a hill at the site at Rova Head. It will initially run on light fuel oil but will have the potential to move to natural gas should gas pipes be laid from the new gas plant being built at Sullom Voe.
Scottish and Southern Energy, who have drawn up the proposals, have said that a peak of 400 people could be employed during the three year building phase of the project.
The rock that will be dug out of the hill will be used to reclaim part of a neighbouring bay for industrial use.
