We would like to light a flame on the Kilimanjaro.

It should bring light and hope beyond our borders.

Lighting Mloka

Project description - Tanzanian energy structure

Annual energy consumption per capita in Tanzania in 2009 was 150 kWh. Only 11% of households are connected to the grid, 80% of them lives in cities. It is a very low percentage considering that the 75% of the total population lives in the rural areas and not in the cities, where the energy available to the population is even lower (less than 5%). The government's plan is to implement 100,000 new connections each year. The energy supply in Tanzania is not reliable and happens to have frequent failures. A countrywide network is simply uneconomical due to the low population density in many areas (39 inhabitants / km2). [REA, GTZ]

Mloka, a city in the Rufiji basin, has been chosen as the site of the project due to the high demand for energy. A connection to the national grid is economically unprofitable and probably not wanted by national park status. The circa 3,500 inhabitants of Mloka live all without electricity. A hybrid system is the stand-alone solution that has been planned. It consists of PV elements and diesel generators. The current energy storage takes place by means of a battery system. Furthermore, there is an emergency energy supply from the local clinic. It is known that medicines must be kept cool and dry. Other medical instruments, e.g. Centrifuges, also needs electricity. Generating electricity for school is a great way to attract qualified teachers and staffs to this rural area. The use of computers and other equipment are made possible. Office buildings and grain mills (which are currently operated by small generators and the use of fossil fuels) allows us to connect to the public network. Enterprises are becoming more flexible and relieved of the transport of fossil fuels. However, the connections mainly benefit the poor, rural households. Similarly, an electrical supply would make the Mloka region attractive to the telecommunications sector. This will have multiple effects on neighboring settlements and will lead to more tourism opportunities for employment and income. This is particularly beneficial to the rural population.


Das Projekt zielt auf die Energieversorgung von Mloka und dem Mbega Camp, durch den Einsatz eines dezentralisierten Mini-grid, ab. Die beiden Orte werden durch eine 4km lange, unterirdische Leitung verbunden. Zusätzlich werden PV-Module auf dem Dach installiert um den Spannungsverlust auszugkeichen. Das Kraftwerk ist mit 2 Dieselgeneratoren und mehreren Batteriebänken verbunden um eine Insellösung zu realisieren. Die Abwärme der Generatoren kann für die Warmwasserversorgung genutzt werden. Dieses moderne Energiesystem wird Erneuerbare Energien als vorrangige Komponente verwenden. (ca. 93%) Zusätzliche PV-Generatorenkapazität im Falle erhöhter Nachfrage kann jederzeit installiert werden. Das Projekt beinhaltet auch Pläne für ein lokales Stromnetz im Dorf, welches alle Haushalte versorgen kann.
