Based on vast field experience, GE offers vertical shaft machines equipped with multi-jet collectors for an output up to ~350 MW and with runner diameters up to 4m.
We provide horizontal shaft single or double runner Pelton turbines with one or two jets. These turbines operate economically with the lowest discharges.
GE-patented Hooped Pelton runners design, with buckets supported by two separate hoops, minimizes stress at bucket fixation, reducing inspection and maintenance costs, and increasing plant availability.
High Velocity Oxy Fuel hard coating technology is well-suited to Pelton runners. The coating is mechanically sprayed onto all surface areas to reduce abrasion and fatigue. The application technique creates a high-density coating with strong bonding capabilities.
GE analyzes flow dynamics to adjust the turbine configuration in areas that are prone to erosion with the help of digital simulation tools that predict the effects of silt abrasion on turbine performance.

The Pelton is an impulse type water turbine invented by Lester Allan Pelton in the 1870s. Peltons are the preferred turbine for hydro-power where the available water source has relatively high head at low flow rates.
The jet(s) of water strike the splitter edge of the double bucket (runner) and is turned through an angle of nearly 180° before falling under gravity into the discharge channel or tailrace.

MICRO-HYDRO INSTALLATION SIZING (PELTON AND TURGO WHEEL TURBINES)
A friend of mine asked me to help size a micro-hydro installation that he was thinking of installing at his cottage. Specifically he wanted to know how to calculate the flow rate of water through a pipe with a given vertical drop. This is a simple pump-sizing problem without a pump, so I thought I would give him a hand. It turned out to be a very interesting topic and I hope you will find it helpful in understanding the concept.
A micro turbine is a wonderful way to generate you own electricity because it is so ecologically friendly. It has little or no impact on the environment and will provide continuous energy year round at low cost. Unfortunately, not many of us can access this resource since it usually requires a large track of land with a stream. For those of us who live in the country, it is possible that you could have a stream nearby on public land that you could access. In this case it may require a longer line (or penstock) to get the water from its source to your land where you will put your micro-turbine. This article is about how you can figure out how much energy will be available considering your terrain and water availability.
The difference in height between the water source and the turbine location is the key to generating power. This height is known as head or more precisely static head. Head is expressed in feet just like height; the difference is when we use the term head, we are actually talking about energy per pound of liquid displaced. So head is just another term for energy, specifically energy per unit weight of liquid displaced. How is this possible? Energy, or useful work can be expressed as pound-feet or lbf-ft in the Imperial system. If I divide this term by lbf, I obtain lbf-ft/lbf or feet (ft) and this is what is known as head.
If I know how many pounds of liquid are displaced per unit time (this is proportional to flow rate in gallons per minute for example) then I know how much power is required since by multiplying head in lbf-ft/lbf by lbf/min, I get a unit of power in lbf-ft/min or foot-pounds per minute.
We know there are 550 lbf-ft/s in a horsepower and 1.34 horsepower in a kilowatt. Therefore, when we know the height difference, or static head, we can immediately get a good idea of how much energy will be available however the analysis is not complete without the flow rate.
Typical micro-hydro installation
The following image shows a typical system that I have seen and which I am familiar with. The stream is located on a hill or incline. The riverbed is accessible and you require some sort of structure that will hold your intake pipe held securely. Remember that heavy rains bring, high water levels and lots of activity within the stream, including the movement of large boulders that could disrupt, or destroy your intake if it is not built robustly enough.
The intake structure shown could also be called a caisson and it is built of re-enforced concrete approximately 3 feet by 3 feet by 2.5 feet high with 6-inch walls. It is basically a thick frame with 4 concrete walls. This is robust enough to stay put in the stream even when the heavy waters come and provides a stable structure to which you can attach your intake pipe. You should provide some sort of filtration device at your pipe intake to prevent branches and other detritus from entering the pipe. A heavy screen mesh is suitable and if you provide holes on the side of the pipe there will be more area for the water to enter the pipe, which causes less pressure drop.
