The bankruptcy of Enron Corp. has evolved into a scandal of enormous proportions involving allegations of fraud, corruption and unethical practices on the part of Enron’s corporate executives, members of its board of directors, external auditors, and high government officials in the USA. No doubt there will be many articles written about various aspects of the Enron scandal. The focus of this paper is on the relationships between Enron’s business model and the deregulatory phase of the American economy during the 1980s and 1990s. It is the argument of this paper that deregulation in the US electricity and natural gas industries fostered the creation of the Enron business model, and that this model was unsustainable, resulting in the demise of Enron Corp. Furthermore, while Enron can be viewed as an example of capitalistic excess, the paper reveals how the Enron business model developed as an American form of a public private partnership, similar to the types of public private partnerships that have been created in recent years in the UK. Investigating Enron as a public private partnership may help us to better understand the role of public private partnerships in contemporary capitalism and shed some light on the advisability of deregulatory schemes and the unintended consequences that can result from such schemes.

The purpose of this study is to investigate factors that deter firms from pursuing foreign direct investment (FDI) in Bangladesh’s power sector.

The study uses a mixed-method approach comprising semi-structured interviews and questionnaires. A quantitative analysis including a one-way analysis of variance and analytical hierarchy process is also included.

The results reveal that political aspects are the most influential barriers impeding FDI in the power sector, followed by economic and financial, societal and regulatory aspects. Of the individual factors, land acquisition/rent/lease, corruption, political interference, an inadequate gas transmission system and a long independent power producers’ approval process are key obstacles deterring FDI in the power sector. The ownership structure matters in ranking decisions to conduct FDI.

The study can assist managers in identifying key factors that deter FDI in the power sector. It can also assist the government to establish the right policies for the sustainable development of FDI in the power sector.

This study is the first of its kind in Bangladesh’s power sector that analyzes the key barriers hindering FDI systematically. It also discusses policies on removing these barriers for sustainable development of FDI in the power sector.

The purpose of the paper is to analyze the effect on centralized dispatching generation cost under the condition where the single‐buyer electric supply industry (ESI) with independent power producer (IPP) scheme (the ESI structure that is widely implemented in developing countries) is opened for bilateral trading. The analysis is based on the Thai power system.

The analysis considers the average generation cost (B/kWh) derived from unit commitment of power generation under three cases – single‐buyer model with must‐run IPP scheme, unconstrained operation case, and the case where bilateral trading is introduced. The analysis is performed for different demand levels.

The results indicate that the operational constraint from the virtual must‐run power purchase agreement under IPP scheme leads to higher generation cost. The choice of allowing IPP to trade through bilateral trading and removal of the must‐run contract shows potential to lessen the operational constraint and lower generation cost can be achieved under some conditions – depending on the plant type and the share of bilateral market in the system. The planning and policy should take into consideration these conditions especially during the transitional period of ESI reform.

The main limitation of the analysis is the availability to recent data. The load factor of the demand curve is taken from the peak day of the year, resulting in higher load factor than the average of Thailand. With lower load factor, the must‐run constraints might be more obvious during the lighter load day and more expensive generation cost can be observed. However, the cases are compared at same demand curve. Therefore, the trend of result will lead to the same conclusion.

Uneconomic operation of the single‐buyer ESI with IPP scheme which has been implemented in many developing countries was clearly determined. The literature shows that the ESI operation can be more efficient when the sector moves towards higher degree of competition, either fully competitive market or bilateral trading. The potential for better operating conditions for bilateral trading has been suggested. The simulation based on the power system of Thailand can be an example for other developing countries operating under the similar ESI structure.

The electric power industry has been moving from a regulated monopoly structure to a deregulated market structure in many countries. The purpose of this study is to comprehensively review the existing markets to study advantages, issues involved and lessons learnt to benefit emerging electricity markets.

The paper employs a comprehensive review of existing competitive electricity market models in USA (California), UK, Australia, Nordic Countries (Norway), and developing country (Chile) to analyze the similarities, differences, weaknesses, and strengths among these markets based on publically available data, literature review and information.

Ongoing or forthcoming electricity sector restructuring activities in some countries can be better designed based on lessons learnt from existing markets and incorporating their own political, technical and economical contexts. A template for design of successful electricity market has also been presented.

This study is limited to a comparative analysis of five markets and can be extended in the future for other existing and emerging electricity markets.

The discussed weaknesses and strengths of existing electricity markets in this study can be practically utilized to improve the electricity industry market structures leading to several social benefits including lower electricity cost.

The comprehensive review and analysis of five existing markets, physically located in different continents, may be used as an assistance or reference guide to benefit the emerging electricity markets in other countries.

The comparative potential impact of electric restructuring laws and attendant regulations on electric utilities and ultimately on their collective human resources in Ireland, Germany and in the Tennessee Valley, USA, is the focus of this research. It includes personal observations of utilities in both EU countries and in the Tennessee Valley as well as personal interviews with utility officials by Dennis Yocom, who has been associated with the electric utility industry for 27 years.

The aim of this paper is to analyze the wind regime at Wainiyaku, Taveuni in Fiji, estimate Annual Energy Production (AEP) using a 275 kW Vergnet wind, and determine its economic viability.

The only grid supply is in the northeast (suburban area) of the island. The main source is diesel generators, which are operated only certain hours per day. The study around Wainiyaku state was essential to determine an alternative continuous source of energy. The wind assessment on the island was based on the data provided by the Department of Energy (Fiji) and WAsP was used to reliably estimate the wind power potential on the island.

The report suggested that Wainiyaku Taveuni is a good site for wind power generation based on mean wind speed at 30 m agl. The software predicted a resource grid for mean wind speed and power density around Wainiyaku. An economic analysis for a prospective wind power generation using Vergnet 275 kW showed a reasonable promise.

The conclusion justifies that a longer period (3y) data are necessary for better accuracy. However, one‐year data are sufficient to predict annual energy production with reasonable certainty.

The paper provides an alternative solution for a continuous supply of electricity for a remote island. It shows the economics of utilizing wind power generator to provide unobstructed supply of electricity. It further explores the saving in foreign exchange for a small Island economy. The analysis of wind regime suggests that an independent power producer may consider investing in a wind farm at Wainiyaku.

The purpose of this paper is to investigate wind power potential of site using wind speed, wind direction and other meteorological data including temperature and air density collected over a period of one year.

The site-specific air density, wind shear, wind power density, annual energy yield and capacity factors have been calculated at 30 and 10 m above the ground level (AGL). The Weibull parameters have been calculated using empirical, maximum likelihood, modified maximum likelihood, energy pattern and graphical methods to determine the other dependent parameters. The accuracies of these methods are determined using correlation coefficient (R²) and root mean square error (RMSE) values.

The site-specific wind shear coefficient was found to be 0.18. The annual mean wind speeds were found to be 5.174 and 4.670 m/s at 30 and 10 m heights, respectively, with corresponding standard deviations of 2.085 and 2.059. The mean wind power densities were found to be 59.50 and 46.75 W/m² at 30 and 10 m heights, respectively. According to the economic assessment, the wind turbine A is capable of producing wind energy at the lowest value of US$ 0.034/kWh.

This assessment provides the sustainable solution of energy which minimizes the dependence on continuous supply of oil and gas to run the conventional power plants that is a major cause of increasing load shedding in the significant industrial and thickly populated city of Pakistan. Also, this will minimize the quarrel between the local power producer and oil and gas supplier during the peak season.

This wind resource assessment has some important social implications including decreasing the environmental issues, enhancing the uninterrupted supply of electricity and decreasing cost of energy per kWh for the masses of Karachi.

The results are showing that the location can be used for installing the wind energy power plant at the lower cost per kWh compared to other energy sources. The wind energy is termed as sustainable solution at the lowest cost.

The publicly listed company, Sea Breeze Power Corp., had its origin in 1990 through a private company called Powerhouse Developments. This company eventually went public through a reverse takeover (RTO), and the new name for the public company was Powerhouse Energy Inc. Powerhouse Developments became a wholly owned subsidiary of the parent company and was purely devoted to developing run-of-river hydroelectric projects. Paul Manson personally became involved through helping the company with the RTO. The original private company, Powerhouse Developments, had been a partnership between a California Investor out of the Central Valley, named Chase Hoffman, and a local man from British Columbia. They had met each other through the real estate business in Hawaii. During this time, Manson was working with the company as a consultant. However, in 2000, there was a falling out between Hoffman and his partner, so Manson was asked to move from purely being a consultant with the company to taking on the title of Corporate Secretary. He was effectively the General Manager, and along with a hydroelectric engineer (Bill Harmond) who had been hired, took over management of the company. Hoffman remained an investor, and Harmond and Manson formed the new management team.

The purpose of this paper is to provide a long‐term assessment of Pakistan's electricity policy in the context of both environmental and resource constraints. To increase the sustainability of energy supply, the Government of Pakistan introduced a series of reforms in the electricity supply sector during 1990‐1995. In response to these policy incentives, most of the independent power producer offers included coal, oil, and/or gas‐based power plants. Considering that Pakistan produces only up to 40 percent of its oil demand domestically and thermal power generation causes CO₂ emissions, there is a great need for an assessment of the existing electricity policy.

Drawing on system dynamics methodology, this study presents and utilizes a dynamic simulation model that captures the dynamics of the sectors underlying the electricity supply system including investments, capital, production, resources, financial resources, and the environment.

The key findings of this study are: policy incentives encouraged thermal‐based generation at the potential expense of hydro power generation; and the evolution of electricity supply related CO₂ emissions exhibits an exponential growth.

While there are other emissions related to the electricity supply system with potentially severe environmental concerns, for example SO₂, this study focuses only on CO₂ emissions.

The paper offers a system dynamics model and provides some useful policy insights for the electricity supply sector of Pakistan.
