Changes

Micro hydroelectric power is different from typical hydroelectric power because it doesn't attempt to significantly interfere with the flow of the river. Typically rated at a maximum capacity of 300 kW hours, the micro hydro systems don't dam rivers, but instead divert a stream of water that flows downhill through a pipeline dropping into the turbine. The turbine then generates electricity which can be stored in batteries and transported to where villagers may need it most.

An important observation is that the cost per installed kilowatt is higher than the figures usually cited in literature. This is partly due to the difficulty analysts have in establishing full costs on a genuinely comparative basis. A significant part of micro hydro costs can be met with difficult to value labour provided by the local community as ‘sweat equity’. Meaningful dollar values for local costs are difficult to establish when they are inflating and rapidly depreciating relative to hard currencies. In addition, there is little consistency in the definition of boundaries of the systems being compared, for instance, how much of the distribution cost, or house wiring, is included, how much of the cost of the civil works contribute to water management and irrigation, and so forth.
