“…This has indeed been indicated by the various studies reviewed (e.g. Hu et al, 2010;Pierce et al, 2013). In the long-term, it will be essential to support stand-alone CSP.…”

“…Apart from increasing the efficiencies of the conventional power station and reducing CO 2 emission, solar aided power generation also provides a better way of utilising solar heat to generate the power. Solar aided power generation would thus contribute to the diversification of electricity generation while ensuring that the cost of electricity generation is affordable, and energy supply security is ensured (Hu et al, 2010;Pierce et al, 2013). In the South African context, Pierce et al (2013) have found solar preheating of feedwater as a more feasible solution in the short-to medium-term, in combination with the coal base.…”

“…The solar aided power generation concept has been developed in order to combine the strengths of two technologies, namely: the traditional regenerative Rankine cycle, which has relatively higher efficiency, and solar heating at relatively low temperature range (Pierce et al, 2013;Hu et al, 2010). Apart from increasing the efficiencies of the conventional power station and reducing CO 2 emission, solar aided power generation also provides a better way of utilising solar heat to generate the power.…”

(Amer and Daim, 2010). It has also been utilised in the renewable energy sector, to assist in filtering alternative technology options in order to support energy policy formulation, energy security and energy independence, among others (Amer and Daim, 2010).Roadmapping consists of two main components: the roadmapping process, which is generally the application; and the roadmap, which is the output of the application (Carvalho et al., 2013). Roadmaps are useful in answering three key questions, as summarised in Table 1. Generally, the visioning question, of 'where we want to go', comes first and determines what will be relevant in the present (Kamtsiou, 2014). These questions can further be represented in a framework -as shown in Generally, there is no standardized approach, methods and tools for developing a roadmap in the public domain; and most of the individual company roadmaps are fragmented and inaccessible (Amer and Daim, 2010). Amer and Daim (2010), however, recommend that the overall goal and objective of a roadmap should guide the choice of an appropriate method and approach to develop a roadmap.This paper therefore reviewed the literature and identified the approaches, methods and tools that have been utilised in roadmapping. This informed the development of the conceptual framework and the choice of the approaches that were utilised for facilitating integration of solar aided power generation within South African energy policy. Solar aided power generation involves the integration of solar thermal and fossil fuel plant technology in order to account for the environmental benefit of the renewable energy technology and the scale, efficiency and reliability of the fossil fuel technology (Pierce et al., 2013).The paper is organised in five sections. Section 2 reviews the literature on the approaches and methods for developing a roadmap. Section 3 uses the literature review to develop a conceptual framework that was applied to provide the initial analysis for the roadmapping of solar aided power generation technology. Section 4 then presents the solar aided power generation case study and the analysis undertaken. Finally, Section 5 presents conclusions and recommendations for integrating solar aided power generation in South Africa. Literature review Overview of roadmapsWithin the field of technology management, roadmapping has proved to be a useful tool for strategic and operational decision-making and Carvalho et al. (2013) and Phaal and Muller (2009) Question DescriptionWhere are we going? This represents the vision, mission, objectives, goals and targets that the roadmap will be achieving.Where are we now? This represents the current state of technology development, products and market development.How can we get there? This represents the policy measures, action plans, research and development programs and strategies (both long-and short-term) that need to be implemented to achieve the vision, goals, objectives.

“…Furthermore, the promotion of the technology in China is limited by the high cost of solar thermal power plants [7,8]. If solar thermal fields are coupled with coal-fired power plants, the cost of solar thermal fields and CO 2 emission can be reduced by sharing power generation systems and heat recovery systems [9]. Moreover, the high temperature and pressure and large capacity of coal-fired power plants can help to reduce fluctuations in solar thermal power generation, cut the capacity of energy storage system, and improve the utilization efficiency of solar thermal energy [10][11][12].…”

Abstract:In this paper, we conduct a techno-economic analysis of a 1000 MWe solar tower aided coal-fired power generation system for the whole life cycle. Firstly, the power output (from coal and solar thermal energy) under variable direct normal irradiance and grid demand are studied. Secondly, a financial assessment is performed, including profits and losses of the plant project. Thirdly, sensitivity analysis is taken on some external factors that can affect the cost or profits and losses of the plant project. The results indicate that the project has high profits with an internal rate of return (IRR) of 8.7%. In addition, the effects of solar tower field cost, power purchase agreement (PPA) price of solar thermal electricity, coal price, and the interest rate of debt on the main criteria decrease gradually. Therefore, it is better to improve solar tower technology first, and then look for low-interest debts from banks to cope with the reduction of PPA price of solar thermal electricity and the increase of coal price. Despite the introduction of solar tower field increasing levelized cost of electricity (LCOE), it contributes to the reduction of CO 2 capture cost compared to the case of standard coal-fired power plants.
