Essays on empirical analysis of multi-unit auctions -- impacts of financial transmission rights on the restructured electricity industryZang, Hailing 01 November 2005 (has links)
This dissertation uses recently developed empirical methodologies for the study
of multi-unit auctions to test the impacts of Financial Transmission Rights (FTRs)
on the competitiveness of restructured electricity markets. FTRs are a special type
of financial option that hedge against volatility in the cost of transporting electricity
over the grid. Policy makers seek to use the prices of FTRs as market signals to
incentivize efficient investment and utilization of transmission capacity. However,
prices will not send the correct signals if market participants strategically use FTRs.
This dissertation uses data from the Texas electricity market to test whether the
prices of FTRs are efficient to achieve such goals. The auctions studied are multiunit,
uniform-price, sealed-bid auctions.
The first part of the dissertation studies the auctions on the spot market of the
wholesale electricity industry. I derive structural empirical models to test theoretical
predictions as to whether bidders fully internalize the effect of FTRs on profits into
their bidding decisions. I find that bidders are learning as to how to optimally bid
above marginal cost for their inframarginal capacities. The bidders also learn to bid
to include FTRs into their profit maximization problem during the course of the first
year. But starting from the second year, they deviated from optimal bidding that
includes FTRs in the profit maximization problems. Counterfactual analysis show that the primary effect of FTRs on market outcomes is changing the level of prices
rather than production efficiency. Finally, I find that in most months, the current
allocations of FTRs are statistically equivalent to the optimal allocations.
The second part of the dissertation studies the bidding behavior in the FTR
auctions. I find that FTRs?? strategic impact on the FTR purchasing behavior is
significant for large bidders ?? firms exercising market power in the FTR auctions.
Second, trader forecasts future FTR credit very accurately while large generators??
forecasts of future FTR credit tends to be biased upward. Finally, The bid shading
patterns are consistent with theoretical predictions and support the existence of
common values.

Turnaround strategies : key factors for corporate recovery in the electricity industry of New Zealand and the Philippines.Joson, Gerardo R. January 1997 (has links)
This research is about the problem of identifying key factors for corporate recovery of electric utilities in New Zealand and the Philippines. Its primary objective is to learn from the experiences of three regulated government utilities and one small private distributor that are involved in the three sectors of electricity business in power generation, transmission and distribution. How these firms survived their decline problems, and managed and sustained their turnaround efforts is the focus of this study. The results indicate the importance of change management, leadership, cost reduction and financial control in reversing the decline of these firms. Also underscored are the crucial role of efficiency improvement and achievement of profit together with winning employee commitment and broad stakeholder support in sustaining the recovery effort.These comparative case studies were undertaken at a time when crises and turbulence affected the management and organisation of electricity businesses in the Asia/Pacific region, particularly New Zealand and the Philippines. Electric utilities in both countries are regulated and less vertically integrated than anywhere else in the region. Significant changes to the ownership and control of these firms and their competitive relationships over the past decade have complicated the way strategic problems and issues have to be resolved. In the meantime, threats and pressures from all stakeholders have made the management and operations of these utilities difficult.Thus, a critical review of their specific circumstances and predicaments is in order for similarly affected enterprises to avoid past errors and to replicate only the strategies that may suit them. In this regard, this work contributes to the enrichment of the existing body of knowledge in business policy and strategic management that has been fast evolving during the ++ / nineties in electric utilities around the world.

Losing power : the struggle for control of South Australia's electricity industrySpoehr, John Douglas January 2008 (has links)
This thesis examines the role that structure and agency play in the outcomes of political contests around privatisation. It does so through a case study of the South Australian Electricity Trust (ETSA), which was established (nationalised) in 1946 and privatised in 1999. The approach taken involves an examination of historical context, particularly the emergence of public enterprise and the nationalisation of the South Australian electricity industry in the post WW2 period.

The Performance Assessment of Public Electricity Enterprise Under Control¡ÐA Case Study of Taipower CompanyYang, Chuan-ming 16 June 2010 (has links)
International electricity industry has encountered many external changes in recently years, like the surge of electricity liberation. Moreover, the issue of energy and green-environment has been a global concern. When facing changes, organizations often adjust their strategies to deal with them. And a good performance evaluation system is a bridge that links the strategy and operation in this process.
Performance management is an indispensable part of long-term development strategy. It can not only transfer executive¡¦s vision into strategy and action plans but also lead the organization to its initial objectives. This research takes into account the differences of nature and operating environment between electricity industry and private corporations and wants to discuss the performance evaluation system and indicators of electricity in changing environment.
After considering the relevant literatures and international practical methods, this research comes up with a performance-evaluation dimension based on industrial value-chain, including manufacturing, supplying, sales and service, and social responsibility. This method takes into account the organization¡¦s mission and vision, and its industrial attribute. Moreover, the consideration of social responsibility is the biggest contribution of this research because it can echo the hiking environmental concern in recent years. In the final simulation result, we can find out that it can, compared with the real grades, reveal the nature of public utility and match the characteristic of stability.

The Impact of the Great Tohoku Earthquake and Tsunami on the Japanese Electricity IndustrySuzuki, Misato 01 April 2013 (has links)
This paper quantifies and analyzes the economic impact of the Great Tohoku Earthquake and tsunami on the Japanese electricity industry using alternative event study methodology. The data set includes daily stock prices of 11 publicly traded electricity companies. This paper investigates the changes in systematic risk, abnormal returns (ARs), and cumulative abnormal returns (CARs) before and after the natural disaster. In addition, I compare the movement of the stock price in the electricity industry with other indices in Japan to investigate the aggregate level impact on the Japanese economy. By examining the economic impact of the earthquake, this paper provides a visual and a numerical representation of the change in investors’ views on the electricity industry. The results showed no statistically significant changes in ARs in the immediate aftermath of the disaster. On the other hand, statistically significant changes in CARs were found for all 11 electricity companies over an extended period following the disaster. Furthermore, there was a statistically significant increase in systematic risk, especially in the nuclear-committed firms. Although the electricity industry was negatively affected, daily stock prices and CARs show that other industries were not as severely affected. These results provide insight to the global economic and the political implication of the disaster.

A review of maintenance scheduling approaches in deregulated power systemsDahal, Keshav P. January 2004 (has links)
Yes / Traditionally, the electricity industry is fully
regulated with a centrally controlled structure. The power
system operator has full technical and costing information as well
as a full control over the operation and maintenance of power
system equipment. Recently, many countries have gone through
privatization of their electricity industries unbundling the
integrated power system into a number of separate deregulated
business entities. The preventive maintenance of power system
equipment in the restructured electricity industries is no longer
controlled centrally, and none of these entities currently have
explicit accountability for maintenance activities. The
approaches used to schedule the maintenance activities in the
centralized system are not ideal for addressing the new
deregulated environments. In recent years a few research
publications has been reported in this area. This paper presents a
review and analysis of these reported maintenance scheduling
approaches for power system equipment in the changed
environment.
