A Japanese company is to build a large factory in the Highlands to make subsea high-voltage cables for wind farms.
The announcement was made on a visit to Japan by MSP Neil Gray, the Energy Secretary.
Sumitomo Electric's Osaka factory has already manufactured and installed subsea links between England and Belgium.
It also has orders for linking the UK to Ireland and projects in Germany.
The BBC says the location, scale and the number of jobs required for the Highland plant have not yet been revealed.
There have been suggestions it could be based at Nigg.
Support
It is not clear the level of Scottish Government support to attract the investment. But it said it was working closely with Scottish Development International and Highlands and Islands Enterprise to advance Sumitomo's presence in Scotland.
The energy secretary is currently on a three-day trade mission to develop relationship with companies across the renewables and supply-chain sectors, and build new inward investment opportunities.
Mr Gray also met Scotland's longest-standing inward investor, Terasaki Electric. to mark its 50th year of investment in Scotland.
The MSP said: "Today's announcement from Sumitomo demonstrates the strength of confidence investors have in our vision for a net-zero economy.
"The company has a proven track record in high-voltage underground cables which will be invaluable to supporting Scotland's rapidly-expanding offshore wind sector.”
Mr Gray said it was clear that there was enormous interest for investment in Scotland's renewables "revolution".
Pipeline of projects
"We have a world-beating pipeline of offshore wind projects, and this visit has demonstrated the important role played by Scotland's international network and the value of growing and developing our partnership with our trusted Japanese partners, both old and new," he said.
Sumitomo's president Osamu Inoue said: "We are delighted to work with the Cabinet Secretary to build a state-of-the-art submarine cable factory in Scotland.
"Sumitomo Electric has the technologies necessary for the development of a green society and will work with the Scottish and UK governments and other stakeholders on future offshore wind power and interconnector projects in the region."
