Hydroelectric Power Systems
Hydro Power Plants,
The three common variations of hydropower plants:
1) Diversion
2) Impoundment
3) Pumped storage.
Many dams were built to collect water for household and commercial use and hydropower was later added. In Australia, there are approximately 68,000 dams of which only 800 produce power. The remaining dams are used primarily for recreation, livestock, flood prevention, water catchment, and crop irrigation.
Hydropower plant sizes range from small home systems to large town size projects producing electrical power as a utility.

- Plus sized manufacturing. 489,600 watt-hours per day
Diversion
Sometimes called “Run of River”, a diversion facility channels a portion of a river through a man-made canal and might not use a dam.
Impoundment
The impoundment hydroelectric power plant facility is the most common. An impoundment facility is characteristically a large hydropower system that uses a dam to store river water in a lake style reservoir.
The water is released from the reservoir which flows through a turbine which drives a generator to produce electrical power. Water may be released to meet changing electrical needs or to regulate the reservoirs level.
Pumped Storage
The third type of hydropower is called “Pumped Storage” and works like a battery, storing the electricity generated from other power sources such as wind, solar and even nuclear for future use.
By pumping water uphill to a tank at higher elevation from the primary water catchment located at a lower elevation, it stores surplus energy when the demand for electricity is low
When the demand for electricity is high the water is released back to the lower catchment which turns a turbine, to generate electricity.
Hydroelectric Power Plant Sizes
Facilities sizes range from large power plants that supply entire cities with electrical power to small and micro plants which are privately managed to supply their own power needs or to sell to power utilities.
Large Hydropower Stations
Large hydropower systems are defined as having at least 30 megawatts in capacity.
Small Hydropower Facilities
Small hydropower projects generate 10 MW or less.
Micro Hydropower Systems
A micro hydropower plant’s capacity is up to 100 kilowatts.
A small micro-hydroelectric power system can produce enough electrical power to run a home, farm or small country town.
Micro Hydro Generators. Pelton and Turgo Rotors. Hydro Jets.
A cost-effective Micro Hydro generator producing 12, 24 or 48 Volts is an perfect charging source If you have a creek on your property with only a few metres of head or pressure.
On a consistent site your micro hydro generator can charge all day all day long which means that you don’t need to have a battery bank like you do with a solar system.
iWolf’s “Stream Engine” micro hydro generator offers high output efficiency. Precision-cast components made from non-corrosive alloys are used for long life and durability.
Hydroelectric Site Assessments
If you have a good ‘hydro site’ location, hydro power is more cost effective per watt than wind or solar power.
Power from water increases proportionally with head and flow rate but is often reduced by pipe friction.
The maximum power for any pipe size peeks when “frictional loss” in the pipe equals one third of the “static head”. An increase in flow rate past this point will only result in producing less power.
Various nozzle sizes are used to control both power and water usage.
A filtered water supply is essential.
The size of the intake mesh should be large enough to reduce the impact of clogging.
The mesh should have holes small enough to prevent any debris from blocking the smallest expected nozzle size.
River Turbines
Our new range of river turbines incorporate structured buoyant stabiliser system, allowing the device to be self-deployed and easily retrieved under the guidance of an operator.
iWolf’s hydroelectric power systems are always deployed at a depth safe for the marine vessels above, and water life below. This portable solution is ideal for use in fisheries, sanctuaries and marine reserves.
