Ministers were also told that Scotland’s forecast share of ScotWind manufacturing spending has fallen over the last three years.
SNP ministers were warned a slump in oil and gas investment is driving the renewable energy supply chain out of Scotland, new documents have revealed.
The Scottish government was also warned that Scotland's forecast share of ScotWind manufacturing expenditure has fallen from 27 per cent in 2023 to 20 per cent in 2026.

But the Scottish government is also facing pressure from climate campaigners calling on SNP ministers to oppose the Rosebank oil field, which would produce around 200 million tonnes of carbon if approved for environmental consent by the UK government and has no energy security argument like the Jackdaw gas field which received a permit last week.
New documents have revealed a risk register presented by industry body, Scottish Renewables, in January warned of a major threat to offshore wind development.
The organisation stated that “historic lows in O&G investment” were “driving supply chains out of Scotland” and having “impacts on operational renewables too.” The document warned over a “genuine challenge to meet grid build out”.
The warning was delivered directly to senior ministers at a meeting of the national strategy for economic transformation delivery board, co-chaired by then deputy first minister Kate Forbes and attended by then net zero secretary Màiri McAllan, who is now John Swinney’s education secretary.

The documents show the renewables industry concerns over Scotland's existing energy supply chain that could be undermined before offshore wind projects are able to replace lost work.
Separate correspondence released by Crown Estate Scotland also shows Scotland's forecast share of ScotWind manufacturing expenditure has fallen from 27 per cent in 2023 to 20 per cent in 2026. Officials pointed to changes in project assumptions and the increasing use of international suppliers as projects developed.
Scottish Conservative energy spokesman, Liam Kerr, said: “These documents contain a stark warning from Scotland's renewable energy industry itself.
“Ministers knew in January that the SNP’s presumption against new oil and gas, and the chilling effect that has had on investment in the North Sea, has actively hampered the development of new industry.
“No wonder the so-called ‘just transition’ they repeatedly promised just hasn’t transpired for thousands of workers who have lost their jobs.”
He added: “When even Scottish Renewables are telling Kate Forbes and Mairi McAllan their cliff-edge approach to developments like Rosebank and Cambo isn’t working, that tells you something.

“But John Swinney still hasn’t backed Rosebank, he hasn’t changed SNP policy and the Scottish Government’s energy strategy is now three and a half years overdue.
“The SNP now need to explain what action they took over this warning, how they are protecting Scotland's energy supply chain and how they will stop a just transition becoming a transition out of Scotland.”
The Scottish government has been approached for comment.
