How CERs give project developers a competitive advantage under the REIPPP 
by Henk Sa and Graham Paul, Ecometrix


REIPPP is a competitive bidding process whereby the successful bidders are awarded long-term PPAs at the offered price in R/MWh. One way of improving a project's competitive edge is via the cross subsidising of its REIPPP bidding price with the revenue stream from the sale of CERs it can generate under the CDM... (more)

Reducing developer risk on the Eskom technical interface for IPPs
by Richard Ahlschlager, Aurecon

 

This paper attempts to highlight some of the developers risk issues encountered in the IPP process, specifi cally around the Eskom technical interface, and proposes strategies that could assist in mitigating risk for all key stakeholders... (more)

Global lessons can boost SA renewables success
by Joanne Reeves, Mott MacDonald

SA's fledgling renewables industry is booming. The government's REIPPP programme, which has allocated 3725 MW to be introduced between 2014 - 2016 (with a further 3200 MW by 2020), is providing a market mechanism to incentivise local and international investment in project development... (more )
Planning a utility scale RE project with emphasis on balance-of-plant
by Vally Padayache and Kobus Morgan, Powertech

When planning a utility scale RE project in SA, the balance-of-plant (BoP) aspects need to be given the same level of consideration and importance as the primary plant to achieve the maximum benefits from a technical, engineering, contractual, time to deliver and quality perspective in order to get the "biggest bang for the buck"...

The challenges of developing utility scale PV in SA 
by Vicky Evans, Vivienne Walsh and Lebohang Matlanyane, Arup

SA has a good enabling environment, and has committed is committed to 17,8 GW of renewable energy capacity by 2030 in its Integrated Resource Plan (IRP). PV accounts for 8,4 GW of this capacity, and at least 1,45 GW of this capacity will be met by the procurement and construction of utility-scale PV facilities... (more )
Technical analysis of the connection of renewable energy generators to the Eskom network
by Mobolaji Bello and Dr. Clinton Carter-Brown, Eskom

Studies are required to assess the impact of RE generators on the network. What studies need to be done by Eskom network and grid planning engineers? What information do Eskom planning engineers require from IPPs? What network information should Eskom planning engineers provide to the generator developers?... (more)
Process for Eskom IPP renewable energy grid integration
by Riaan Smit, Eskom

What consultation and advice is offered by Eskom to potential developers? What process is followed for costing and grid connection? The processes is discussed to enable the grid integration of potential renewable energy projects to the Eskom grid... (more)
Studies for wind energy facility grid code compliance in South Africa
by Jarrad Wright, Paul Tuson and Dr. John Van Coller

This paper provides a guide to engineers wishing to perform grid code compliance studies in the SA context. Suggested approaches to perform grid code integration studies as well as selected results and analysis from various technical investigations of a proposed wind energy facility (WEF) in South Africa are presented...

Connecting wind power to the grid
by Mick Barlow and Ernst Camm, S&C Electric
 
With a major increase in wind generation and other forms of renewable generation, the performance of both transmission and distribution networks are changing significantly from the traditional model of large centralized generation... (more )
Grid support stability for reliable, renewable power
by Vince Scaini, Eaton Corporation 
 
As renewable energy penetration continues to expand, finding the best ways to store energy is increasingly important to accommodate those cloudy, rainy days. This is true for both the utilities that deliver electricity and the organizations investing in photovoltaic (PV) solar... (more)
Solar thermal power offers opportunities for local manufacturers of power plant components
by Ivan Fenyves, BHR

Solar thermal power, and certain variants of it, offer great opportunities for local manufacturers of conventional thermal power station mechanical / thermal equipment, such as pressure vessels, heat exchangers, general and specialised piping, etc... (more)
Report confirms concentrated solar thermal energy storage offers significant benefits
by Daniel Swartz, Brightsource

In December 2012 the Concentrating Solar Power Alliance (CSPA) issued a technical report titled, "The economic and reliability benefits of CSP with thermal energy storage: recent studies and research needs." The report summarizes analysis conducted by national energy labs and academic institutions... (more)
Judge CSP on its value, not only on its price
by Jonathan de Vries, SASTELA

These are challenging times for CSP developers. Arguably their biggest challenge is to persuade the powers that be that CSP costs more because it delivers more; that its price is higher because it can provide real value to the national grid, and even save Eskom and consumers a good deal of money... (more )
The REIPPP and the drive for local content and manufacturing
by Dirk de Vos, QED Solutions

Much has been made about green industries being a new vehicle for industrial development in South Africa. For now the focus is mainly on increased manufacturing of components as inputs into the renewable energy independent producers procurement programme (REIPPP) currently underway... (more)
