RE Module 1

Utility Responsibilities with respect to RPPs

 NOTE: This course has been merged with Module 2 into a 3-day course

Utility responsibilities have been defined in NRS 048-4; however, with the advent of Renewable Power Producers (RPPs), keeping to these responsibilities is more crucial due to the risk that the integration of distributed sources of renewable energy brought about. The South African Grid Code published a chapter dedicated to RPPs, known as the RPP Grid Code. The first edition was published in 2012 and the latest revision in November 2014 whilst another revision is expected soon.

A key concern for utilities, is that these generators have varying power outputs and are not despatched by the utility or System Operator. Also, these RPPs inject energy at points in the network where it was designed for voltage drops, resulting in potentially high voltage rises and they may contribute to increased levels in voltage harmonics, flicker and unbalance.

Utilities own and operate the distribution network and special consideration is needed when a RPP is connected. This responsibility is analysed and the requirements in maintaining PQ levels within the minimum technical standards of the NRS 048-2, is explored in context of the NRS 048-4:

  • What are the utility responsibilities when integrating an RPP into a distribution network?
  • The operational principles of the NRS 048-4.
  • The role of the (Draft) Power Quality Directive in planning for a Renewable Energy Producer (RPP).
  • Communication and cooperation with customers (including RPPs).
  • How to plan for good PQ.
  • How to assess the potential impact on PQ due to a distorting customer such as an RPP.
  • How to coordinate PQ impacts of multiple customers (including RPPs).


  • Price is R 8 000 (Excl. VAT)  for a 3-day course in Potchefstroom. It can be presented anywhere in the SADC region but the additional expenses incurred, has to be negotiated.
  • Students arrange lodging.
  • Lunches and refreshments and all course material are included.
  •  Supporting software and/or case studies are distributed by flash disk.

Payment is needed BEFORE the course – a 10% (R800) discount will be given for payments received before the course. The NWU will invoice and payment is then made to the NWU. Please help SAPQI to expedite payment, as expenses are not spared to ensure that participants have a memorable experience at the NWU.

  • SAPQI promote the case of PQ in Africa for Africa by using the profits towards research equipment and student support. SAPQI is not a commercial course provider in competition with the rest of the industry. We only focus on value for money.
  • If payment is not made before the course, the course fee remains at R 8 000 (Excl. VAT).

CPD Points:
Three (3) CPD points are issued by means of a NWU attendance certificate, accredited by ECSA. It is an attendance-only course, no assessment of the outcomes is made and therefore not in the category of a short course certificate i.e. no NQF level accreditation applies.

Workshop date:

Module 1 and Module 2 combined into a single 3-day course
