Once the design is complete and all of the consents are in place the final stage of the project is construction.  One of the strengths of Renewables First is that we don't just consult and design, we build systems as well.  It is only through the construction of hydropower systems that you truly learn the subtleties of good hydropower design.  We have a reliable team of sub-contractors that assist us during the installation phase while Renewables First provide the project management expertise and supervision during key project stages, as well as our own staff that specialise in turbine set-up and system commissioning.

The following pictures show a typical construction sequence, over six months, from site preparation, construction of the structures, installation of the turbine, generator and electrical system and commissioning.  For more detail the picture thumbnails can be expanded by clicking them, then use the 'back' button in your browser to return to this page.

 
Some sites have existing historical infrastructure. This picture shows the old bypass sluice channel walls being rebuilt ready for installation of a new sluice and elver-pass before the new turbine house and intake and discharge channels are constructed. Most projects start with large excavations, as shown here.  The main reason for including this picture is to give you an idea of the scale of the project, even for a relatively small hydropower system.  We will damage the lawn!

The turbine inlet adaptor on the right (goes between the turbine and the intake screen) and the draft tube on the left (discharges the water from the turbine into the discharge sump). Both of these parts get concreted into the turbine house structure to ensure the turbine house stays watertight. This picture shows the space that the turbine will occupy.  The water will enter from the right, turn through 90° inside the turbine, then discharge through the hole in the floor into the discharge sump underneath.  Once the turbine is installed the whole area will be watertight, with no visible water.

This project demonstrates the continuing viability of traditional water mills which, used appropriately, can mill flour more cheaply than the diesel mills which are threatening to replace them. The increase in income from an upgraded mill is such that the investment can be paid back in about a year - an excellent rate of return, which bodes well for the rapid expansion of the model across the region.

The Eastern Africa office in Kenya has installed very small 'pico-hydro' power systems for two remote communities on the slopes of Mount Kenya.

These projects provide over 200 homes with lights and power points. As well as giving light to study by and power to recharge appliances like radios, the electricity also opens up new income-generating possibilities to villagers, from chicken farming to charging points for mobile phones – a social and economic lifeline to health workers, family and markets elsewhere.

The schemes’ size and design avoid environmental disruption while providing a cheaper and safer alternative to kerosene and lead-based dry cells. Equally important is ITDG’s success in bringing about a proposed change of policy in Kenya to help create a decentralised electricity market, allowing micro-schemes such as these to thrive countrywide.
