The South Australia experience is noteworthy in a global power mix set to increasingly shift to renewable energy. The rapid growth of renewables raises intermittency challenges and has already changed the power mix with coal phased out and gas utilisation reduced. However, despite this reduction, gas still remains the most important way to ensure uninterrupted power supply. Meanwhile, South Australia is experimenting with numerous new technologies, in addition to reintroducing diesel generation, in an attempt to ensure security of power supply. Currently, these technologies are not economic compared to gas. Looking ahead South Australia is projected to have installed renewable energy capacity exceed its peak demand by 2020. This paper asks what needs to be considered given the increasing role of renewables in the energy mix? Can battery technology combined with renewables offer a commercial solution for replacing either base load or peak load gas plants? What is required for system security to 2035? If renewables and batteries are proven commercial then what are the implications for gas? To answer these questions, this paper will assess the extent to which renewable and battery technology costs will fall in South Australia. We will compare renewable and gas cost projections for 2018, 2025 and 2035. Using proprietary dispatch modelling we will then assess what the growth in renewables means for annually, monthly and daily gas demand. Demand will undoubtedly decline and become more volatile. This poses challenges. We will assess whether and how current gas contracting terms need to change to ensure that gas has a continued role in ensuring system security in South Australia.

The Impact

The paper examines the impact of the National Economic Empowerment and Development Strategy (NEEDS) on the private sector by looking at the contribution the power sector had made in realizing the goal of making private enterprise the engine of growth in Nigeria. NEEDS reform is to  transform the power sector into one led by the private sector, with the role of government  restricted primarily in policy formulation and establishment of an appropriate legal and regulatory framework.  The paper discusses among many things: an overview of power supply in Nigeria; the effect of power sector on private sectors; challenges of the sector; as well as the ways forward. The paper concludes that there is   need to put concerted effort to generate adequate power supply to enable the private sector thrives and serves as engine of growth in Nigeria.

The One

Currently, Russian electric power sector is influenced by two divergent tendencies: on the one hand, we can observe a structural transformation of the industry and increasing role of innovations; on the other hand, it is still subject to regulation, while reliability and safety of power supply remain of paramount importance. This situation creates a unique opportunity to explore which innovation strategies are chosen by companies and which factors have the greatest influence on their decisions. A qualitative study was conducted based on a set of semi-structured interviews with several managers of Russian power companies. Further analysis allowed to reveal the dominant innovation strategies employed within the industry: traditional contracts, in-house development, closed and open innovation ecosystems. This study also revealed factors that determine the choice of an innovation strategy: goals of the firm and type of market it aims to operate at. The results provide managers with insights allowing them to make better-grounded decisions in terms of choosing an innovation strategy within various settings

Year 2000

Over the last decades, the discussion on climate change, together with catastrophic events in the power sector, has raised global interest for radical policy changes. Since the year 2000, Germany´s Renewable Energy Sources Act (EEG) has been a forerunner in triggering large-scale decentralized deployment of renewable energy. Although built on a relatively large social consensus, the consequences of the German ‘Energiewende’ have also raised conflicts between communities and investor-oriented project developers. This chapter reviews the increasing role of energy co-operatives as means to involve civil society, mitigate conflicts in planning, and distribute subsidies more evenly among a variety of often rural stakeholders.

This chapter presents case studies of three recent renewable energy independent power producer (IPP) tender programs in Sub-Saharan Africa (SSA), in Uganda, Zambia, and South Africa. Using competitive tenders to select IPP projects is rare in Africa, but is viewed as an effective way of lowering project costs. And with the rapid reductions in the costs associated with wind and solar projects, renewable energy IPP projects may represent the power sector public–private partnerships (PPPs) of the future. These case studies detail the role of development partners in designing and implementing the first two of these programs and compare their performance with that of the South African program, a program designed and managed almost exclusively by South African officials and their advisers. What are the lessons that can be learned from these two distinct approaches? What impact do these kinds of programs have on the “IPP policy dilemma” described in Chapter 8?

With the charging and discharging of grid-tied Energy Storage Systems (ESS), distribution network could shift load from peak period or suppress the fluctuation of renewable energy. Constraints of both grid and ESS are analyzed in the present paper, and definition of power supply & storage capacity of distribution network with ESS is proposed, which quantifies the ability of distribution network to shift load or adopt renewable energy generation. Operating optimization model is proposed for the operation of distribution network considering peak load shifting based on power supply & storage capacity, and the model is tested and verified in case study.

Uninterrupted Power Supply

Power system reliability and resiliency involves availability of uninterrupted power supply to loads. With ever-increasing natural and man-made disturbances in power grid, the need of alternate renewable based source of supply is gaining more attention. This paper presents an efficient renewable energy-based single stage configuration for standalone application to provide uninterrupted power supply to critical loads in case of grid power interruption. This configuration can also be used for grid integration during peak load demand of power. The advancement in research of Multilevel Inverter (MLI) relating to high voltage with high power energy control enabled increased use of MLI in renewable energy, especially PV and fuel cell-based systems. The renewable energy-based configuration proposed in this paper uses Cross T-Type (CT-Type) MLI which provides quality output power from solar PV, fuel cell etc. Moreover, the absence of any DC-DC converter reduces complexity and makes the system more economical for grid integration. The overall system performance improves compared to existing methods in terms of total harmonic distortion (THD), total standing voltage (TSV), number of levels, number of components requirement and efficiency.

Implementation Of Innovations

While the benefits and advantages of using renewable energies are remarkable, and their prices have been decreasing dramatically and are expected to fall further, the diffusion and adoption of renewable energies still lag fossil energies. This paper improves our understanding regarding the role of the interrelationship among businesses (as an example of B2B networking amongst parent and subsidiary firms). Furthermore, it demonstrates the way/s that such interrelationships can contribute to the diffusion and adoption of sustainable and energy-efficient technologies. This study describes four diffusion channels in the interrelated firms which can help with promoting and using renewable and sustainable energies. The paper also reports the actual share of each diffusion channel contributing to implementing sustainable energy-efficient technologies in practice. The findings suggest that parent organisations enforce the majority (over 50%) of sustainable and energy-efficient technologies implemented in a B2B environment. In comparison, inter-subsidiary relationships are responsible for less than 30% of the implemented sustainable and energy-efficient technologies in organisations. The findings are in line with the forced perspective theory. They could, to some degree, explain the differences in the levels of implementation of sustainable and energy-efficient technologies in practice. These findings can help practitioners prioritise the diffusion channels when they want to facilitate the implementation of new technologies in their organisations. While some organisations may expect a more successful implementation of innovations initiated by subsidiaries than those enforced by parent organisations, the levels of success of the adoption of sustainable and energy-efficient technologies are not examined in this study. Further research is recommended to investigate the extent of association between different diffusion channels and the levels of success in terms of the adoption of innovation. We did not find similar studies to compare the results, which could be one of the limitations of this study.

Presently the country faces a peak load shortage of 30% of total demand and the shortage of gas supply resulting in about 10% of power plants leaving idle. It also reveals that about 1-2% GDP growth declined annually owing to the shortage of energy and poorer ability of power generation. The present study seeks to analyze the issues and challenges of renewable energy (RE) in Bangladesh with special emphasis on prospects of energy generation at rural areas of Bangladesh and subsequent policy analyses. Electricity generation through RE and implementation of energy efficiency and conservation including the RE policies and their analyses will explore to meet the future unmet demand in power sector. Lessening of dependency on natural gas is one of the top agenda of the government, in addition Bangladesh has enormous prospects of RE (solar energy) to meet the unmet demand particularly at the remote and off grid areas. By this time, the government of Bangladesh has planned to generate 5% of generation (i.e., 800MW) by 2015 and subsequently 10% (i.e., 2000MW) by 2020 from renewable sources and 20% of total generation by nuclear, renewable and cross border by 2030 out of40,000 MW total expected generations. In this paper possible attempts have been made to identify the problems and prospects related to the RE particularly for solar energy at rural areas and their possible recommendations for future development towards achieving millennium goal.J.
