Net-Billing Rules for Licensed Distributors (NERSA)
Net Billing Rules for Embedded Generators, covering tariffs and billing, distributor permitting processes, and technical standards, amongst other areas.
Template Municipal Wheeling Guideline
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
Asset Costing Tool
This tool assists municipalities calculate the total cost of a network upgrade for the purpose of integrating new generators into the network.
Calculating Fair Use-of-System Charges for Wheeling
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).
Avoided Costs Calculator Tool
This spreadsheet assists municipalities determine their avoided purchase costs when an embedded generator exports electricity into the municipality's distribution grid (SEA, 2022).
SSEG Tariff Excel Tool
An excel-based tool for testing proposed SSEG tariffs against municipal revenue impact as well as customer business case impact. Solar PV SSEG only. The guide to using the tool is separately downloadable.
How to undertake a simplified municipal cost of supply study
This paper provides a practical step-by-step guide to performing a COS study, using the National Energy Regulator of South Africa (NERSA)-endorsed simplified COS tool. The methodology described is based on NERSA’s COS Framework and draws on the NRS 058 where needed. The input data is kept as simple as reasonably
System Cost Analysis of Embedded Generation vs Utility-Scale Solar PV
This paper analysis the impact of small-scale embedded generation (SSEG) on the cost of running South Africa's power system. It investigates whether utility-scale solar PV is cheaper than embedded generation. SSEG reduces overall system costs by reducing electricity losses and resulting fuel expenditure, and, in instances where peak demand is
NERSA Cost of Supply Framework
NERSA developed the Cost of Supply (COS) Framework for licensed electricity distributors ('licensees') in South Africa. The framework will be used as a guideline to licensees when developing their COS studies.
NRS 058: Cost of Supply Methodology
The NRS 058 is a draft Cost of Supply methodology for application in the electricity distribution industry. The NRS 058 provides a deeper level of detail to NERSA's Cost of Supply Framework, and the two documents can therefore be used in conjunction.
The Impact of Small Scale Embedded Generation on Municipal Revenue
This paper which was presented at the AMEU Conference 2019 explores the impact of some of the approved municipal SSEG tariffs on municipal revenue and customer ‘business case’ and outlines key tariff elements to balance access and cost recovery, until such time as detailed costing studies provide specific tariff building
Small-Scale Embedded Generation (SSEG) Tariff Guidelines Summary
Summarises the principles for setting SSEG tariff, with a focus on solar PV, and discusses revenue impact and customer business case considerations. Case studies are presented and broad guidelines given for tariff setting (Sustainable Energy Africa, 2019).
GIZ-SALGA SSEG Tariff Design: Model Training Presentation
This is is presentation of the excel spreadsheet model that assists municipalities with solar PV SSEG tariff design in a way that balances municipal revenue requirements with customer business case for Solar PV installations. The spreadsheet model is downloadable separately (Genesis, SALGA & GIZ, 2017).
GIZ-SALGA SSEG Tariff Excel Tool Guide
Guide to the excel-based tool for testing proposed SSEG tariffs against municipal revenue impact as well as customer business case impact. Solar PV SSEG only. The spreadsheet tool is separately downloadable (Genesis Analytics (Pty) Ltd and SALGA, 2017).
South African Distribution Tariff Code
The tariff code sets out the objectives for pricing and tariff structures for distribution retail and network services. NERSA regulates the setting of prices and the structure of tariffs for all distribution related services (NERSA, 2014).
Electricity Pricing Policy (EPP)
Electricity Pricing Policy (EPP) of the South African Electricity Supply Industry (Department of Minerals and Energy, 2008).
National Retail Tariff Guideline
National Electricity Regulator guideline on electricity pricing in South African Electricity Distribution Industry (NERSA, 2004).
