Fact Sheet: Generating biogas from the digestion of municipal wastewater sludge

GIZ-SAGEN supports capacity building measures to improve the operation and maintenance of municipal wastewater treatment plants, and to promote the use of generated biogas for power and heat applications. This fact sheet describes how a practical guideline i.e. the "Anaerobic Digestion of Municipal Wastewater Sludge" was developed for this purpose, and piloted in three training sessions in order to test the concept and lend to the development of the guideline.

A Practical Guideline for Energy Efficiency Audits at Waste Water Treatment Plants

The purpose of this guideline is to provide an overview and methodology description of how to perform an energy efficiency audit at a waste water treatment plant. Specific focus is placed on how to execute an audit with its associated calculations and compiling an informed and effective audit report. Two case study audits are also included as examples to the guideline user on how the information in the guideline is applied in practice, as demonstrated at two municipal WWTWs. The guideline serves as the basis for a training course to establish a standardised methodology for conducting energy audits in the WWTW sector, as well as to develop capacity and skills to perform such an audit.  The guide covers the following topics:

  • Understanding of the purpose and focus areas of a WWTW EE Audit ,
  • Understanding of the typical treatment processes’ EE impact,
  • How to approach a WWTW EE Audit,
  • How and where to obtain information,
  • How to process the obtained information,
  • How to go about implementation of the findings,
  • What targets can reasonably be expected.

Anaerobic Digestion of Municipal Wastewater Sludge: A Practical Guideline (DOWNLOAD)

About: The Anaerobic Digestion Guideline is a practical guideline for wastewater practitioners and managers involved in the planning, design, operation, maintenance and management of WWTW. The guideline is based on the premise of the American “Capable Plant” concept which demonstrates a holistic management process for the beneficial use of biosolids and biogas naturally generated during the anaerobic digestion process. The Guideline will form the basis of a series of training and capacity building events for municipalities offered through WISA.

Disclaimer: The use of the Guideline is restricted to private use and may not be used for income generation purposes. Should any content be cited from the guideline, kindly acknowledge the authors and GIZ as publisher. The content of the guideline has been compiled by subject matter experts, peer reviewed by sector experts and tested during three pilot training sessions in municipalities.

The electricity distribution in Germany and South Africa- A review of policy and regulations

This Discussion paper summarises the challenges and opportunities of changes in the German power market triggered by liberalisation and the Energiewende, and relates them to the energy transition challenge in South Africa. Based on German and South African experiences, the paper formulates suggestions for municipal utilities and a possible way forward for a new electricity distribution market design in South Africa.

This Paper is based on the outcomes of the South African-German Policy Discussion Workshop on Energy Market Design and Municipal Utility Business Models from 4th-8th December 2017 in Eschborn, Germany, jointly organised by SAGEN and the Secretariat of the South African German Energy Partnership (EP).

Assessing the impact of increasing shares of variable generation on system operations in South Africa (Flexibility Study)

This study assesses changing flexibility requirements in the South African power system resulting from increased levels of variable renewable generation (solar PV and wind), with a time horizon until 2030. The expansion (and decommissioning) of both renewable and conventional power plants is modelled from now until 2030 according to the base case of the draft Integrated Resource Plan (IRP), as published in December 2016.

Analysis of options for the future allocation of PV farms in South Africa

The aim of the studies presented in this report is to quantify the economic impact of different strategies for the deployment utility scale PV farms in South Africa. These are referred to as ‘allocation strategies’.

Three different allocation strategy scenarios for a total of 8,4GW of utility scale PV farms in South Africa have been considered. These are summarized as follows:

  • Scenario A: As planned” This scenario is according to the existing applications for PV farms where there is a total of, 6,4GW of PV in the ‘Solar Corridor’ (see Figure 2), and 2GW distributed elsewhere in the country.
  • Scenario B: Close to load centers” Here, only 2,6GW of PV is considered in the Solar Corridor, the remaining 5,8GW is distributed across the country.
  • Scenario C: According to REDZs [1]” For this scenario, PV farms have been allocated in the Renewable Energy Development Zones (REDS), as identified by CSIR and DEA within the SEA project [1]. In this scenario, 2,8 GW is considered in the Solar Corridor, and 5,6GW is distributed predominantly in the REDZs.
