The report provides an overview the steps municipalities must take to facilitate electricity wheeling in their jurisdictions and provides an overview of the progress municipalities to wheel. (SALGA, 2023)

This spreadsheet assists municipalities determine the revenue impact of electricity wheeling. The model requires various inputs about the municipality, the electricity tariffs, the generator, and the offtaker. The model accounts for wind or solar generators connecting to Eskom’s network, and accommodates embedded solar generations. For all generator arrangements, the offtaker receiving wheeled energy must be a municipal customer. Developed by Sustainable Energy Africa as part of a Western Cape-funded project.

This guideline describes the process and requirements for third party energy providers to wheel electrical energy on a Local Municipality’s distribution grid. This guideline will be regularly reviewed and amended to keep abreast with the rapid developments in the wheeling space, and as the municipality’s technical capacity is built through engagements with the wheeling industry.

As renewable energy costs decline and companies strive to decarbonise their power supply, there is a growing call for municipalities to facilitate wheeling of electricity across their distribution networks. This paper explores how municipalities can calculate use-of-system charges for providing access to their networks for wheeling (Dippenaar et al, 2022).

The spreadsheet model evaluates the impact on municipal revenue and household electricity costs if a low/mid-income household invests in a grid-tied rooftop photovoltaic (PV) system. The model compares household electricity costs for two scenarios called ‘Without SSEG’ (without a rooftop PV system, i.e. the default) and ‘With SSEG’ (with a rooftop PV system) (Conway and

This report describes, in detail, a spreadsheet model that evaluates the impact on municipal revenue and household electricity costs if the household invests in a grid-tied rooftop photovoltaic (PV) system and identifies areas of potential which could improve the financial case for LIHH & MIHH without unduly prejudicing municipal income or requiring significant subsidisation (Conway
