Energy consultancy and development of a stand-alone isle network energy supply concept for Ndanda Abbey

A hydroelectric power plant combined with a diesel generator currently supplies the area of Ndanda Abbey in Tanzania. There is also the possibility of a connection to the public grid, but this is characterized by regular outages and frequency fluctuations. Since along the local carpentry workshop and school there is a hospital, the demand regarding quality of supply are very high. Due to the increased costs for diesel, the diesel generator is to be replaced by a photovoltaic system.

The aim of the project is on the one hand to determine the optimal dimensioning of the photovoltaic system, its optimal interconnection with the other existing power generators and a possibly necessary battery storage. Since the experience of the FfE shows that at least 10 - 20 % of the energy consumption can be saved by an energy consultation, primarily an energy consultation is carried out at the location. In the course of the inspection, the electricians on site (trained, instructors and apprentices) will also be trained on the subject of efficient energy systems.

All in all, the steps are structured as follows:

  • Analysis of the available data on energy supply and demand
  • Compilation of a suitable english energy consultancy questionnaire1
  • Derivation of a measurement concept
  • Evaluation and analysis of the measured data
  • Derivation and quantification of energy efficiency measures1
  • Creation of an energy concept
  • On-site training of the employees on the various steps for the creation of measurement concepts and for the maintenance of the planned plant components1

1 The expenses incurred for the project are partly provided by the staff of the FfE on a voluntary basis.
