Pico hydro power is rarely fed into a power grid, but in most cases electricity is delivered to a village or a workshop. As there are varying definitions of the power range of of "micro" and "pico", it is advantageous to specify each project's power output in kW.

"Self made" Pico turbines usually are waterwheels or propeller turbines. The concept of pressurised pipes over high heads seems not to be common sense. One reason may be that channeling water towards a deep drop requires abstraction of existing landscape. It cannot be seen from a single standpoint. Informative materials may help to raise awareness for such potentials.

Introduction

Pico hydro power: Turbines smaller than 10 kW are usually called "pico". Pico hydro power is rarely fed into a power grid, but in most cases electricity is delivered to a village or a workshop. As there are varying definitions of the power range of of "micro" and "pico", it is advantageous to specify each project's power output in kW.

Concept

Pico hydropower is the only form of small renewable energy production which works continuously without battery storage. Where applicable it is the most cost efficient solution to supply electrical energy. Pico turbines can provide power for small clusters or even single households

Individual hydropower supply cuts out the efforts of organising a community. Identifying, planning and managing takes a higher proportion of the whole installation efforts as smaller a sites becomes. For less consumers served, specialists have similar efforts in accessing sites. On the other hand small installation are more likely to be "do it your self".
With guidance by info materials and advise from a local shop consumers could be enabled to install their own pico turbine. If pico hydropower can become an "over the counter" product it meets a immense demand.
One example may be the north of Laos where cheap Chinese pico-turbines flooded the country in ten-thousands or more.

Requirements:

  • suitable locations
  • accessibility of affordable equipment (turbines) and installation know how


Electricity has a high value so working systems will spread quickly.
In many countries self-made solutions can be found, whereby a wooden water wheel is coupled with a car-alternator to produce electricity. Professional solutions increase efficiency reliability and safety.

Pico Hydro Turbines

Principles of Turbines for high, medium and low head conditions

Pico-Turbines.jpg

Each type of turbine has its own features.

The main characteristic it's the turbines suitability for different heads and different amounts of water (see picture left).

In general a Crossflow turbine has the wides application range and is very tolerant against debris in water.

"Self made" Pico turbines usually are waterwheels or propeller turbines. The concept of pressurised pipes over high heads seems not to be common sense. One reason may be that channeling water towards a deep drop requires abstraction of existing landscape. It cannot be seen from a single standpoint. Informative materials may help to raise awareness for such potentials.

TC60 (100 W)

CIT in Bandung, Indonesia developed the "TC60" inspired by Vietnamese/Chinese low cost Open Flume turbine (OF turbine) design. Sales started at the beginning of 2007. With a price less than 300 USD makes TC60 an option for private energy supply for single households. It produces 100 W at site specifications of only 3 m head and a flow < 10 l/s. Total installation cost depend on cable length from turbine to house. (50 USD/ 100 m).

Chances and Challenges

Advantages

  • Cheapest technical solution for independent power supply.
  • Clean, sustain-/ renewable energy resource.
  • Reliable => long lifetime as it is based upon robust mechanical techniques.
  • Minimal running and follow up costs (unlike batteries at PV systems).
  • Small maintenance efforts, which are easy to follow.


Disadvantages

  • Site specific power output => pre-feasibility check required.
  • Site specific installation => basic hydro know-how required.
  • All cost are investment cost => upfront.
  • Mostly shared connections => require community organised operation, management and use of water resources.
  • Difficult access of clients => requires hubs and/or supply structure.

Capacity

Power output is limited by local conditions of height and amount of water available. Turbines are chosen by site conditions.
The following is an example for one specific turbine designed in Indonesia.


Explanation:

Tp100 application-range example.jpg


The colored lines indicate the power output at certain height/flow situations. The red horizontal line such turbine is technically not feasible, the blue "2 kW" line indicates a tech. maximum (for this specific turbine). The dotted lines separate three areas wherein turbines have certain sizes (30, 60 and 100 mm wide).
Example: at a site with 15 m height difference and a flow of 15 l/s the turbine can produce 1.5 kW (it will have a width of 60 mm). If on the same site (15 m) 25 l/s flow, power output will be 1.8 kW.

Remark:
to produce the same electric power by photovoltaic you require about 50 m2 PV-panels (and min. 20 batteries).
