The rule of thumb is $3,000,000 to $6,000,000 per MW for plants larger than 10 MW. · The larger the plant, the lesser the cost per MW.
Small hydropower (SHP) definitions are typically based on power capacity or design. · SHP net present value ranges from $-1.8 to $30 million; -$551,382/kW to
# Micro-Hydro Power. If there is not a steep drop, then a larger volume of water flow will be needed instead. The upfront cost of hydro power can be quite high, but on a suitable site, it can be a good long-term investment. On off-grid sites, a hydro turbine should be much better in the long term than running a diesel generator for electricity. ## Micro Hydro at CAT. We installed a second-hand micro-hydro turbine to provide much of the electricity we needed around the site. ## How much electricity can I generate from a water turbine? The power you could produce will depend on the ‘head’ of water (the vertical drop) and the flow rate. To estimate the energy that could be available, multiply the flow rate (in litres per second) by the head (in metres), and then by 10 (acceleration due to gravity). ## How much will a micro hydro turbine cost?

To build a micro-hydropower system, you need access to flowing water on your property. Other considerations for a potential micro-hydropower site include its power output, economics, permits, and water rights. To see if a micro-hydropower system would work for you, you will want to determine the amount of power that you can obtain from the flowing water on your site. Once you've determined the head and flow, then you can use a simple equation to estimate the power output for a system with 50% to 70% efficiency or more, which is representative of most micro-hydropower systems. ### Determining the “Head” at Your Potential Microhydropower Site. In a potential microhydropower site, head is the vertical distance that water falls. The hose-tube method for determining head involves taking stream-depth measurements across the width of the stream you intend to use for your system -- from the point at which you want to place the penstock to the point at which you want to place the turbine.

Components of a micro-hydropower system A micro-hydropower system may have the following components depending on the site: ➤ an intake or weir to divert stream flow from the water course ➤ a canal/pipeline to carry the water flow to the forebay from the intake ➤ a forebay tank and trash rack to filter debris and prevent it from being drawn into the turbine at the penstock pipe intake ➤ a penstock pipe to convey the water to the powerhouse ➤ a powerhouse, in which a water turbine (Pelton, Turgo, Francis, propeller turbines or pump-as-turbine) converts the energy of the flowing or falling water into mechanical energy that drives a generator, which in turn generates electrical power ➤ a control mechanism (load controllers) to provide stable electrical power ➤ a tailrace through which the water is released back to the river or stream ➤ electrical transmission lines to deliver the power to its destination LEGEND A – Intake/weir B – Canal/pipeline C – Forebay tank D – Penstock pipe E – Powerhouse F – Tailrace G – Transmission line Principal components of a micro-hydropower system M E F G D C B A Site potential The amount of energy available from a creek, stream or river depends on the amount of water flow per second (flow rate), the height (head) from which water falls and the force of gravity.
