Electricity market reform risks "failing" Scotland, according to the energy minister.
Changes to the UK's Energy Bill debated in the House of Lords last week will remove Holyrood's powers over an aspect of renewable energy policy, Fergus Ewing said.
He also criticised British ministers for pressing ahead with nuclear power, arguing it is at odds with Scottish ambitions.
"Developments ranging from small hydro stations and innovative projects in our islands, to floating offshore wind, carbon capture technology and vital stations such as Longannet - all of these are placed at risk by the UK Government's reforms," he said.
"The UK Government must listen to the concerns raised by industry that would see electricity market reform failing in its objectives.
"The Scottish Government will not support an outcome which sacrifices our renewable ambitions in preference to discredited, expensive and imported nuclear technology."
In a statement to MSPs, Mr Ewing focused on the Lords' attempt to remove discretion over Renewables Obligation (RO) in Scotland.
The scheme was introduced in 2002 to provide incentives for large-scale renewable electricity in the UK, according to the UK Government's Department of Energy and Climate Change.
Mr Ewing said the Lords' action cut through a live Scottish Government consultation and caused "consternation" in the industry.
"This Parliament has supported the electricity market form process but based on an outcome consistent with Scottish policy priorities and ambitions," he told MSPs.
"Such an outcome now looks at best uncertain.
"The removal of Scottish parliamentary discretion in the matter of the RO is troubling and demands an explanation.
"The chamber should also understand the threats posed by electricity market reform to Scotland's renewables ambitions and our established position as a provider of secure energy supplies."
Labour finance spokesman Iain Gray said bickering between Holyrood and Westminster is not helpful.
"Somebody needs to bang these two governments' heads together, get them to stop dithering and find a resolution which protects the single British electricity market Scotland needs," he said.
"Currently, we receive a third of the UK money for renewables, although we have less than a tenth of the UK population, so maintaining a single British energy market is vital to ensure that costs associated with renewables don't fall solely on the shoulders of Scots."
