Plans which could see an average spend of £1.5billion in Scotland on each of 17 new offshore wind projects were published yesterday by Crown Estate Scotland (CES).
This represents a massive investment of more than £25billion from successful applicants in the recent ScotWind leasing round.
The supply chain development statement outlooks show initial commitments from these firms. They detail how companies could source products, materials and labour to construct, erect, and service the fixed and floating offshore wind projects.
However, one union has already expressed fears that Scottish industry could yet again lose out to foreign rivals when it comes to landing big contracts for work for renewables developments north of the border.
CES said yesterday that a key part of ScotWind is ensuring a focus from the outset on supply-chain capacity to develop and deliver the projects.
It has mandated that applicants must outline supply chain commitments as part of their application for an option agreement - with commitments then updated throughout development as project specifics such as timing and technology become clearer, and the development of the supply chain progresses.
Colin Palmer, director of marine for CES, said: "The breadth and scale of these initial commitments from ScotWind developers is encouraging, as is their ambition to help Scotland reach net zero. However, the challenges in delivering on these ambitions - which will evolve as project details become clearer - should not be underestimated. It will require a truly-collaborative approach from all involved to ensure the huge potential for transformative economic development, job creation and a just transition is realised."
CES said the outlooks make clear the challenges faced by the sector in realising ScotWind's potential benefits.
Constraints identified include a lack of grid availability, bottlenecks for construction and fabrication at preferred sites, and the skills within the labour market.
However, the outlooks also highlight the extensive experience and knowledge within Scotland, which has been accumulated via the oil and gas industry and growing renewable energy sector.
Net Zero and Energy Secretary Michael Matheson said: "As the world's largest offshore wind leasing round, ScotWind puts us at the forefront of the global development of offshore wind - and represents a massive step forward in our net zero transformation.
"The publication of these supply chain outlooks demonstrates the truly-unprecedented scale of the opportunities that this leasing round will present, not just for our regional and national economies, but to deliver a true just transition for our energy sector, harnessing existing talent and expertise and creating and delivering good, green jobs across Scotland's supply chain.
"There will be some challenges to overcome as we embark on this exciting expansion in renewable energy - such as grid capacity and unfair transmission charging.
"Offshore wind is rapidly becoming one of the cheapest forms of electricity at our disposal to protect consumers and ensure our energy security whilst delivering our climate obligations, and the Scottish Government will use every lever at our disposal to harness to ensure a greener, fairer future for everyone."
To date, most work for the offshore wind farms operating off Scotland has gone overseas.
It is hoped that ScotWind will deliver a step change in that regard, providing decades of work for the local supply chain.
But GMB Scotland senior organiser Gary Cook told Energy Voice: "No one should have optimism that the next generation of Scotland's renewables manufacturing story will be any different to the broken promises of the last decade.
"A scan of the successful ScotWind bidders and their plans shows familiar international players from the spaghetti bowl of renewables and marine construction firms that have profited handsomely from our bill-payer subsidised offshore wind industry, while exporting tens of thousands of green jobs to the rest of the world at the expense of Scottish working-class communities.
"It's business as usual for our offshore wind sector, Scotland for sale - and government ministers know it."
