Hydro power developments bring major local investment the Environment and Sustainability Committee heard on 1 March 2012.
Speaking on behalf of North Wales Hydro Power, Richard Rees stressed that unlike wind turbine developments, the majority of the project money is spent on the work force locally and only a small amount on the turbine itself.
Hydro development in Wales is being unfairly treated in comparison to the other home nations, according to Mr Rees as he predicted that this will affect the Welsh rural economy for generations.
Ewan Campbell - Lendrum from Infinis warned that when considering planning permission it was easy to look at potential negative of scheme but not as easy to foresee the lost income through the jobs and local investment.
An other concern raised was that proposed hydropower developments in Wales will not be able to achieve the return to investors anticipated by the UK government to encourage additional hydropower generation.
Witnesses also told committee members that the Welsh approach to water usage puts Wales at a competitive disadvantage for new hydropower investment when compared to England and Scotland.
