The "Onshore Wind in Scotland" report by consultancy Everoze, commissioned by trade body Scottish Renewables, identified ten barriers that could markedly reduce costs of Scotland's 7GW of wind capacity in the pipeline.
The biggest saving is made by using the latest technology, the report found. Current planning guidelines in the UK limits the use of turbines with a tip height of over 125 metres.
Everoze suggested use of the latest turbine technology could save £11/MWh when compared to current prices.
"Deploying the latest generation of turbines has the biggest impact on costs, reducing them by £11/MWh," said Scottish Renewables senior policy manager Lindsay Roberts.
"The report sets out just how competitive onshore wind in Scotland can be, and shows that it makes no sense for the UK Government to exclude the technology from long-term contracts for clean power. Without it, we will all be paying for more expensive alternatives," Roberts added.
The report said improved planning, repowering, grid upgrades, increase consent terms, and storage could all contribute to the cost reduction.
