The developer put the 43MW A'Chruach and 55MW Galawhistle projects on hold in August due to uncertainty over the possibility of Scotland breaking away from the UK.
Construction is now expected to start at the Galawhistle development to the south of Glasgow next month. Work on A'Chruach in west Scotland will begin late next year, with the project close to finalising turbine contracts, connection to the grid and financing.
Infinis intended for both projects to qualify for the UK's existing renewables obligation subsidy scheme, but the referendum on 18 September had raised questions about whether projects in an independent Scotland would qualify for support from the UK government.
As such, Infinis had said that the projects would only go ahead once the outcome of the Scottish referendum, and its potential effect on energy policy, was known.
