exploring the use of deep level gold mines in south africa for underground pumped Hydroelectric Energy storage schemes
Renewable & Sustainable Energy Reviews, 2017Co-Authors: Frank Winde, Friederike Kaiser, Ewald ErasmusAbstract:Abstract This paper explores the viability of deep level gold mines in the Far West Rand (FWR) gold field, South Africa (SA), for underground pumped Hydroelectric Energy storage (UPHES). Ultra-deep, non-flooded shafts, extensive underground storage space, and abundance of water from an overlying karst aquifer make gold mines in the FWR exceptionally suitable for UPHES. With generating capacities ranging from 0.5 to over 1.5 Gigawatts per plant, UPHESs are not only of potential significance to local gold mines suffering from frequent power cuts, but also for closing the peak load shortfall of the national grid as well as for storing surplus Energy from the rapidly growing renewable Energy sector. Furthermore, UPHES systems are able to avert large future expenditure for post-closure mine water management by preventing the flooding of mine voids in an ecologically and economically sustainable manner. Moreover, UPHES provides two of the most critical elements for a successful post-closure development of former mining towns: Energy and water. It protects scarce water resources in the semi-arid region and generates peak-demand electricity. Using an example of a gold mine located in the water-rich part of the FWR, this study found that UPHES is both, technically feasible and economically viable. It is strongly recommended to conduct a more detailed follow-up study as a base for establishing the world's first reference plant in SA.

pumped Hydroelectric Energy storage analysing global development and assessing potential applications in turkey based on vision 2023 Hydroelectricity wind and solar Energy targets
Renewable & Sustainable Energy Reviews, 2017Co-Authors: Mehmet MelikogluAbstract:Abstract According to the Vision 2023 agenda, the Turkish government plans to produce 30% of Turkey's electricity demand from renewable Energy sources in 2023. This means Hydroelectric, wind and solar Energy capacities would increase to 36,000 MW, 20,000 MW and 3000 MW, respectively. Increased Hydroelectric capacity would indeed benefit stability and flexibility of the existing Energy infrastructure. However, increased wind and solar capacity could bring intermittency problems due to nature of these Energy sources. Recently, pumped Hydroelectric Energy storage (PHES) has become a hot topic in Turkey. And, its potential applications via synergistic utilisation with wind and solar Energy to solve the aforementioned intermittency problems is being discussed. Yet, detailed information in the literature about PHES in Turkey is scarce. Therefore, this paper was intended to provide this crucial information. Detailed analysis showed even if all obstacles are overcome and all potential PHES capacity is used PHES could only provide a storage capacity worth equivalent to 0.6–0.8% of Turkey's annual electricity demand in 2023. It is estimated that the overnight capital cost required to develop this PHES potential is between 3.6 and 6.5 billion US$. Even so, there would be serious economic risks of PHES plants. Because, PHES systems are currently net consumers of Energy. Current study also showed that instead of focusing on PHES, flexibility of Turkish electricity market could be sustained by diversifying Energy sources and increasing nuclear Energy capacity. It is estimated that an additional 490 MW of nuclear capacity could provide the same potential PHES capacity. By this way, intermittency problems associated with increased share of solar and wind Energy can be easily tackled without imperilling the Vision 2023 Energy targets.
