Where there is access to a suitable river or stream, micro-hydro
can be a very attractive option for producing electricity.
The term 'micro-hydro' is usually used to describe schemes up to
100kW. Micro-hydro is usually run-of-river, meaning that no significant
water storage is required, unlike large hydro schemes which require
large reservoirs.
In most cases, private schemes generate between a few hundred
watts and 25kW. Above this level, schemes are usually commercially
operated. Hydro systems at the 25 to 100 kW scale can be connected
to the main electricity grid or alternatively can be used in an
off-grid system where electricity is either used directly by appliances
or is stored through the use of batteries. Single households might
be able to go completely 'off-grid' where there is a suitable hydro
source nearby. In cases where excess power is generated this can
also be sold back into the grid.
Many farms in Borders of Scotland are situated on the sites of
old mills, and therefore maybe suitable for micro-hydro generation.
However, costs are quite high and a pre-feasibility study will be
needed to assess the situation.
