CENTRE FOR RENEWABLE AND SUSTAINABLE ENERGY STUDIES

LIST OF COMPLETED PROJECTS

CRSES has a team of competent engineers and project managers who can assist clients with on- and off-grid renewable energy solutions. The dynamic group includes engineering expertise in the following disciplines: Mechanical, Mechatronic, Electrical, Process and Civil. The Centre is also well positioned to assemble expertise from the broader University community and private industry to participate in multidisciplinary projects. The past projects are listed under each year below:

PV ROOFTOP STUDY - HESSEQUA

Client: GreenCape Initiative

Scope: Review of the current technical, regulatory and financial frameworks governing (or constraining) the rooftop PV market in South Africa, and benchmark it against international best practices. The study was also to investigate different technical, financial and social-economic scenarios to stimulate the rooftop PV market in South Africa and provide recommendations on how to implement the most promising of these in a typical midsize municipality.

Status: Completed

GRID PLANNING PHASE 3 – WASA DATA (CRSES2012/07)

Client: ESKOM

Scope: Acquiring the WASA data in the appropriate GIS format, refinement of environmental and developmental criteria used in the GIS methodology and generation of results. Currently the WASA wind data is in a digital format that is accessible via an online interface. The first step will be to translate or acquire the WASA map in shapefile format. After the WASA map has been obtained the refinement of the GIS criteria will be conducted. This involves including criteria as determined by the regional strategic environmental assessment conducted by the Western Cape government. The criteria to be included will only depend on available digitized maps. Specific areas of layer refinement include more up-to-date representation of housing in rural areas (farm houses etc.) and location of private-game reserves.

Status: Completed

BROADBASED RE POTENTIAL OF SOUTH AFRICA (CRSES2012/12)

Client: ESKOM

Scope: Acquiring the underlying data used to determine the various different renewable resource capacities in the appropriate GIS format, application of environmental and developmental criteria used; and generation of results as GIS layers.

Status: Completed

SOLAR STUDY: EFFECT OF CLOUDS ON SOLAR PLANTS (CRSES2012/14)

Client: ESKOM

Scope: To quantify the impact of clouds on PV power production from PV installations for preparation / defining of appropriate operational strategies and management of solar power fluctuations. All types of weather and season are analysed and most extreme cases are selected. The data can be used for optimum site selection in terms of maximising the output and minimising the impact on the grid. The focus of the study is to enhance understanding of the impact of cloud cover and movement and its typical patterns. The study will provide key support information for minimizing negative effects of PV on grid stability / load. The study will provide preparatory information for grid analysis and for implementation of forecast tools.

Status: Completed

INSTALLATION AND MEASUREMENTS AT SOLAR STATIONS IN UPINGTON

Client: Sasol New Energy

Scope: The aim of this project is to measure solar irradiation at a site specified by the client for at least 12 months. Other weather data (wind, temperature, humidity, rainfall, etc.) will also be measured. A satellite derived data time series will be updated with ground measured solar data obtained from Eskom. Later the on-site measured solar data will further be used to update the satellite data.

Status: Completed

DNI MEASURING EQUIPMENT PROCUREMENT, INSTALLATION, COMMISSIONING AND REPORTING

Client: SASOL New Energy

Scope: The aim of the study is to establish the solar radiation in terms of DNI at various locations of interest to Sasol. The data will be used to design possible solar fields which will in turn generate energy to be used in various ways. These solar fields are highly capital intensive and their optimal design will have a deciding influence on the feasibility of any solar related project. It is therefore crucial that the base case for the design, namely the solar resource, be determined accurately.

Status: Completed

RWANDA RENEWABLE ENERGY STRATEGY

Client: UNEP

Scope: The United Nations Environmental Programme (UNEP) intends to undertake a Green Economy Sector Study on Energy in Rwanda. The study aims to support the Vision 2020 that the government developed, which aims to transform Rwanda's economy in promoting economic development, providing policy reduction strategies, and promoting green growth and climate resilience.

Vision 2020 is subsequently based on several pillars which are in turn affected by a number of cross-cutting issues including, gender equality and sustainable environmental and natural resource management. This green economy sector study will focus on the energy sector of the Rwandan economy. It will include a review of green economy-related policies and initiatives, pertaining to the energy sector that already exists in the country in order to enable synergies with on-going processes and provide an opportunity to build partnerships in achieving the Vision 2020.

Status: Completed

REVIEW OF OCEAN ENERGY RESOURCE DATA

Client: TIA / SANEDI

Scope: In this project a review of the available ocean energy resource data available in South Africa was conducted, some of the past resource assessments were summarised and two case studies were completed in order to pave the way to a better understanding of the available ocean energy resource along the South African coast.

Status: Completed

OWS SCALING/TESTING DEVICE (CRSES2013/20)

Client: Natural Energy Systems

Scope: Natural Energy Systems has approached CRSES in order to help quantify the device testing and scaling parameters which are needed for the development of their novel OWC concept. The specific emphasis on this invention is the unique turbine which has been developed by Natural Energy Systems. The focus of the work done by CRSES is to establish a set of test parameters which will lead to results with integrity whilst making use of the established model test rig that is currently in existence.

Status: Completed

SOLAR AND WIND ENERGY FOR RURAL WATER SUPPLY PROJECTS IN ETHIOPIA

Client: Ethiopian Ministry of Water and Energy

Scope: Ethiopia has an abundance of solar and wind energy resource that is currently not being exploited. The country also has a significant need to pump water, which is done either by hand or by fossil fuel powered pumps. In order to address these challenges experts needed to be trained to be competent in utilising the available natural resources of available energy to pump water. This project consisted of the training of a group of 26 Ethiopian delegates on specifically pumping water using solar and wind energy.

Status: Completed

ESKOM RE ANALYST - APPOINTMENT OF A CONSULTANT AS A RESOURCE ANALYST MANAGER TO CONDUCT RESOURCE MEASUREMENT AND ANALYSIS TO ASSESS SITE POTENTIAL IN SUPPORT OF ESKOM'S RENEWABLES BUSINESS UNIT STRATEGIES

Client: Eskom Holdings (Pty) Ltd

Scope: A joint venture between the Centre for Renewable and Sustainable Energy Studies at Stellenbosch University and 3E Renewable Energy Services for the appointment of a consultant as a Resource Analyst Manager to conduct resource measurement and analysis to assess site potential in support of Eskom’s Renewables Business Unit strategies. The Resource Analyst Manager (in this case Solar (Stellenbosch University) and Wind (3E)) was required to provide analytical support to the Renewables Business Unit with regards to wind and solar resource assessment, energy capture derivation, site conditions, and wind farm optimization. The study was required to aid robust project development and assessment of suitability and economic viability of sites. Two employees from Eskom were trained for 12 months at SU (Solar) and 3E (Wind) respectively. The scope of work and deliverables were to develop, plan, coordinate, analyse and manage all aspects of wind, solar and other renewable energy resources.
