Aurora Energy Services has been boosted to the tune of £20m after investment from the Scottish National Investment Bank.
The cash will "bolster growth and expand its network of regional training hubs" as it looks to support the renewable supply chain.
The Inverness-headquartered company also owns renewable training facilities in Aberdeen and Huntly.
The banks funding will also be used to create more Scottish jobs and support further expansion internationally. Aurora currently employs 275 staff in Scotland and the US.
Jimmy Williamson, executive director at the Scottish National Investment Bank, said: "Aurora has an exceptional team from a proven background of expertise honed in the oil and gas and industrials markets, now turning those skills to support the renewables sector.
"For Scotland to be able to harness the opportunities in renewable energy infrastructure, the right skills and a ready workforce are a critical dependency.
"Aurora’s remit to develop new talent and retrain workers who already have deep, critical energy sector knowledge is a vital link in realising the potential before us.
"Aurora aligns with The Bank’s net zero and placemaking missions and has a key energy transition theme at its core. It is a great platform focused on helping create a long-term, valuable industrial cluster for the people of Scotland that will really allow us to become world leaders in the renewables sector."
Chief executive of Aurora Douglas Duguid added: "The wind sector is an important part of Aurora’s future expansion plans, but other renewable technologies like hydrogen, Carbon Capture & Storage and pumped hydro are also key, and the Bank’s support means we can speed up our strategic expansion in those areas.
"We are a Scottish business, firmly rooted in the Highlands but with an international footprint, and the Bank’s financial support will be an important factor as we close in on other international acquisitions which are in the pipeline.
"Our international reach, and the previous experience of our management team in building global businesses, will ensure a healthy export of Scottish expertise in skills and technology, counterbalanced with importing new technological advancements which can benefit Scotland’s nascent renewables sector."
