How to stimulate the South African rooftop PV market without putting municipalities’ financial stability at risk: A “Net Feed-in Tariff” proposal [PowerPoint slides]. Presented at NERSA Offices, Pretoria. According to Solarbuzz, the prices of installed PV system and PV modules have dropped significantly in the past three years. With the abundance of solar irradiation in South Africa, the levelised costs of energy (LCOE) for PV is very close to the average system price of electricity, hence it is becoming a viable supplemental alternative for commercial and residential electricity customers. The Centre for Scientific and Industrial Research (CSIR) has identified some views and concerns by various stakeholders regarding rooftop PV development and these are listed in Table 2 below. Table 2: Some concerns of distributed PV Generators
(i) be established through a tendering procedure which is fair, equitable, transparent, competitive and (ii) provide for private sector participation.’ or Eskom customer in these processes. Electricity Regulation Act (2006), Section 35 (1) ‘The Regulator may, after consultation with […] municipalities that reticulate electricity […] make guidelines and publish codes of conduct and practice, or make rules by notice in the Gazette.’ Defines partial involvement of Eskom and municipalities into regulation activities. Electricity Regulation Act on New Generation Capacity (2009), Definition IPP ‘“Independent Power Producer" or "IPP" means any undertaking by any person or entity, in which the government of South Africa does not hold a controlling ownership interest (whether direct or indirect) […]’ Effectively implies that local government cannot hold a direct or indirect controlling interest in an IPP. The Electricity Pricing Policy GN 1398 of 19 December 2008 N/A The electricity Pricing policy is silent on these types of systems and does not indicate how they should be treated. The Renewable Code This code outlines grid connection conditions to comply with for all sizes of renewable energy generators The grid connection conditions in this code are more relevant to a bigger size of generation plants connecting to higher levels of voltage and not at low voltage levels. As a result, this code warrants much more stringent performance from these plants. The Distribution code The distribution code outlines all requirements for: Metering Connection conditions for embedded generators but assuming it would be thermal or hydro power stations. This code is rather limited with regard to dealing with issues of embedded renewable generation. It assumes that all renewable energy related issues will be dealt with within the scope of the renewable energy grid code.
Limitation of liability Information exchange Designing of tariffs etc. The NRS 097-2-1:2010 The NRS 097-2-3:2014 This specification sets out the minimum technical statutory requirements for the utility interface, the embedded generator and the utility distribution network with respect to embedded generation. The specification applies to embedded generators smaller than 100kW which are connected to an LV utility network. This specification sets out the technical requirements for the utility interface, the embedded generator and the utility distribution network with respect to embedded generation. The specification applies to embedded generators smaller than 1000kVA connected to low voltage networks. This is limited to only LV connected embedded generators and by implication no embedded generator of this size will be or is expected to be connected to the MV utility network. Also according to this specification, the limit does not cover the correct threshold up-to or just below 1000kW. This NRS is in the course of being reviewed to cater for the correct threshold. This is limited to only LV connected embedded generators and by implication no embedded generator of this size will be or is expected to be connected to the MV utility network.
