The available power, in kilowatts, from such a system can be calculated by the equation P=Q*H/k, where Q is the flow rate in gallons per minute, H is the static head, and k is a constant of 5,310 gal*ft/min*kW. [7] For instance, for a system with a flow of 500 gallons per minute and a static head of 60 feet, the theoretical maximum power output ...
Small hydro can be further subdivided into mini hydro, usually defined as 100 to 1,000 kilowatts (kW), and micro hydro which is 5 to 100 kW. Micro hydro is usually the application of hydroelectric power sized for smaller communities, single families or small enterprise. The smallest installations are pico hydro, below 5 kW.
Micro hydropower to generate electricity in Nepal started with Pharping plant with an installed capacity of 500 kW in 1911 followed by Sundarijal and Panauti, in 1936 and 1965 respectively. Up to 1980, the focus was laid primarily on large-scale power generation through large hydro and thermal means, the micro-hydro potential remained untapped.
A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

A complete PV-solar system. The whole of the equipment required to set up a working system and for an off-the-grid generation and/or a hook up to the electricity grid herefore is termed a balance of system [10] and is composed of the following parts with PV-systems:
Cost-per-kilowatt estimates for these projects can be lower than for surface projects if they use existing underground mine space. There are limited opportunities involving suitable underground space, but the number of underground pumped storage opportunities may increase if abandoned coal mines prove suitable.
A specific example is the Renewable Electricity Production Tax Credit. This is a federal tax credit aimed at promoting renewable energy resources. To qualify, the hydro source must have a minimum capacity of 150 kW. This subsidy is given for the first ten years of production. Organizations receive $.011/kWh. .
This article provides a list of the largest hydroelectric power stations by generating capacity. Only plants with capacity larger than 3,000 MW are listed. The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power.
