The firm flow is often defined as the flow available at least 95 % of the time. For micro hydro power plant, it's important to ensure the power plant running through a year. Generally, micro hydro power plant is designed at the firm flow of Flow Duration Curve (FDC) or estimated as minimum of flow.

Some of the energy generated by a micro-small hydro plant is used by the plant itself for auxiliary equipment (e.g. shut-off valves, by-pass gates, protection and control systems, etc.) lighting, heating, etc. For micro hydro, parasitic electricity losses are typically minimal. Parasitic electricity losses can range from 1 to 3 %. A value of 2 % is appropriate for most small hydro plants.

Annual downtime losses is the estimated percentage of time that the micro-small hydro plant will have to be shut down in order to carry out routine and emergency maintenance. This value is one of the factors used to calculate the available annual energy production of the small hydro plant.

A value of 4 % represents approximately 15 days of downtime (assuming 100 % capacity factor) and is an appropriate value for most small hydro plants. For micro-small hydro plants located in regions where increased maintenance requirements are anticipated (e.g. due to flood problems), more downtime should be anticipated and a higher value (e.g. 6 %) should be used.
