Feasibility Study of Pumped Storage System for Application in Amhara Region, EthiopiaTilahun, Mastewal Alemu January 2012 (has links)
In these days environmental issues are critical. Environmental concerns mainly rise from energy productions. Fortunately Ethiopia is trying to use renewable energy sources as a means for electrical power production and it is a great start for a long, tiresome green energy journey. The basic job to be done in green energy sectors is to maximize the capacity of renewable technologies to fulfil the best efficiency. Intermittent nature of the energy production and their inefficiency to meet peak load demands are the basic problems in renewable energy sectors. Ethiopia’s electrical power production is mainly dependent on hydropower; according to latest data from EEPCO hydro covers 88% of the total production. There are two major nature of this power plant; since the working medium is water it is mainly dependent on the nature of the seasons and secondly it rarely meets peak load demands. After the erection of the power plant the energy production is not time dependent; it can produce power continuously; but the consumption is time dependent which is defined as peak hours and off-peak hours. There is excess load in time of off-peak hours and scarcity in peak hours. So this work can help to maximize the capacity of the water for production by using technological advancements to produce lot of energy in almost full capacity throughout the year to full fill the need of our country. Tana Beles hydropower plant is the largest hydropower plant which starts to work in May, 2010 with an investment cost of $500 million and capacity of 460 MW. The project is planted in Amhara region using the water source of Lake Tana. To make this large and very necessary renewable energy resource sustainable using energy storage system will be vital. This study will figure out a pumped storage system for the hydropower plant for additional power production and for the sustainability of the water resource. Pumped storage system is the only viable, large-scale resource that is being broadly utilized today for storing energy, and it offers the best option available for harnessing off-peak generation from renewable sources. The contributions of pumped storage hydro to our nation’s transmission grid by providing stability services, storage capacity needs, and expanding the green job market are considerable today. The high energy demand of the pump will be considered to be covered using the excess electrical power production during night or weekends and if the resource is available using wind solar PV hybrid systems. The author will try to assess the technology not only for other mini hydro power plants but also for irrigation and other purposes merely in Amhara region, Ethiopia. The feasibility of the system will be considered technically and economically for the hydropower plant.

Linking fiscal decentralization and local financial governance: a case of district level decentralization in the Amhara region, EthiopiaMulugeta, Meselu Alamnie January 2014 (has links)
Philosophiae Doctor - PhD / The prime aim of this thesis is to examine the link between fiscal decentralization and local financial governance in fiscally empowered woreda administrations (districts) of the Amhara region in Ethiopia. Local financial governance has been one of the reasons and arguably the crucial one that drives many countries to subscribe to fiscal decentralization. The presumption is that public finance mobilization and spending can be implemented in a more efficient, responsive, transparent and accountable manner at the local government level than at the centre. Nonetheless, empirical studies show that the linkage between fiscal decentralization and these local financial governance benefits is not automatic. Several developing countries that have tried to implement fiscal decentralization have failed to realise the promised financial governance gains largely due to design and implementation flaws. A review of the various theoretical perspectives suggest that local financial governance is not a factor of just devolution of fiscal power but also other intervening forces such as financial management system, citizen voicing mechanisms and the social and political context. It is within the framework of this theoretical argument that this study sought to investigate how
the mixed and incomplete efforts of the district level fiscal decentralization program in the Amhara region has impacted on financial governance of woreda administrations. The study assesses the efficacy and role of various initiatives of the district level decentralization program of the Amhara region, such as the fiscal empowerment of woredas; financial management system reforms; citizen voicing mechanisms and political party structures and system in influencing woreda financial governance. To this end, the investigation process largely took the form of an interpretative approach employing a combination of various methods of gathering the required qualitative and
quantitative data from respondents and documents in the selected four case woredas or
districts. Findings on the assessment of the intergovernmental relations to measure the adequacy of devolution of fiscal power indicate that, despite the constitutional provision that affords the woredas the power to mobilize and spend public finance for the provision of various local public services, several design and implementation shortcomings have constrained woreda administrations from exercising such power effectively. As a result, the district level fiscal decentralization framework of the Amhara region appears to have features of decentralization by de-concentration rather than by devolution. Despite the extensive financial management reforms that have been undertaken, the research findings indicate that the financial management system in woreda administrations faces a range of challenges triggered largely by important design and implementation shortcomings. It is observed that the ‘getting the basics right first’ reforms in various financial management processes of woreda administrations are not only incomplete but also found to be inconsistent with each other and therefore could not serve their purpose. Furthermore, there has not been any other change in the last two decades since the initial implementation of these reforms despite such serious shortcomings. Most importantly, woreda administrations could not properly implement the techniques, methods, procedures and rules that constituted the reform process due to serious implementation problems such as the lack of manpower competency and problems associated with the lack of administrative accountability. The results of the study’s assessment regarding the practice of social accountability show that
currently there is no arrangement for citizens to participate in public financial decisions and controls. In general, people have little interest in participating in the meetings organised by woreda government. Formal and informal community based organizations suffer from important capcity constraints, and the lack of strong civil society organizations to support these community based organizations makes such problems more difficult to resolve. However, local communities did indicate that they would be interested in participating in financial and budgeting processes if a number of conditions were satisfied. These included the availability of adequate and relevant information; the introduction of genuine forms of participation in which citizens were empowered; and evidence that popular participation was making a visible impact on financial decisions related to service delivery in their surroundings. The assessment of the ruling party structure and system suggests that the centralized system of the regional ruling party has created a dominant relationship between party organs at various levels so much sothat it has undermined the fiscal discretionary power of woreda administrations; blurred relationship between party and woreda financial management systems; and undermined direct voicing. Consequently, the genuine devolution of fiscal power, the effective implementation of the decentralised financial management systems, and
direct participation of citizens are unlikely to be realised within the current ruling party
system and structure. Moreover, the study shows that the intergovernmental relations, the implementation of financial management reforms and direct involvement of people influence each other. The evidence suggests that the effective implementation of the financial management reforms is not possible without genuine devolution of fiscal power and arrangements for the activeinvolvement of citizens. Despite these limitations and shortcomings, the research nevertheless reveals that the decentralization process has achieved some positive results, such as the expansion of access to basic services; the economic use of resources for such expansion; the mobilization of resources from local communities; and the streamlining of a number of bureaucratic processes. However, the prevalence of various financial governance challenges such as excessive budget transfers; low budget execution; uneconomical procurement; illicit spending; budget pressure; inadequate revenue collection; poor financial transparency; and compromised accountability in fiscally decentralized woreda administrations means the promised local financial governance benefits of fiscal decentralization are remain largely unrealized. The evidences in the study strongly suggest that the shortcomings in the design and implementation of intergovernmental relations, financial management system reforms,
and direct voicing mechanisms areresponsible in combination with each other for these local financial governance challenges. Thus, the study concludes that local financial governance is a result of a complex network of interactions of intergovernmental relations, public financial management arrangements and social accountability mechanisms. The success of initiatives to improve local financial governance is dependent on contextual factors such as the capacity of civil society organizations and the ruling party system and structure. Therefore, while recommending further efforts of genuine devolution of power, in particular through the continuation of the financial management reform processes towards full-fledged reforms, the study contends that
opening enough space for the proliferation of civil society organizations and alternative
political parties will be the main priority.

The Nexus between water supply infrastructure and socio-economic developments in Amhara Region, Ethiopia, 1941-2005Derb Tefera Tassew 05 1900 (has links)
This thesis examines the historical introduction and spatial expansion of modern water supply infrastructure in Amhara region across the three successive regimes: imperial, military, and EPRDF. It attempts to explore the institutional setup of the three governments together with their policies and strategies. The study also aims at giving an idea about the socio-economic changes registered because of improved access to safe water. Furthermore, it assesses the water consumption and conservation pattern of the society and the environmental impact of the water infrastructure development.
Modern infrastructure development in Ethiopia traced its beginning back to the late 19th century. Safe drinking water supply had been one of those modern infrastructures introduced in Addis Ababa. Not long afterwards, it proliferated to the provinces. In Amhara region, drinking water supply infrastructure construction began in the early 20th century. However, this thesis inquired whether there was a programmed water supply infrastructure development before the mid-1950s or not. The water supply work started gaining momentum and became a state program in the late imperial period. However, it was affected by financial, technological and trained human resource constraints, lack of appropriate institution, defective management systems, and improper implementation methods.
The military government had strengthened water supply institutions and improved workers'
expertise. These developments helped the water supply infrastructure work to be executed in a programmed manner. Yet, financial restraints, the incessant political chaos of the time and the accompanied disruptive working environment had greatly impacted the temporal and spatial coverage of the water supply infrastructure development.
The promising start of the Derg period did not continue with similar pace during the early years of the EPRDF rule. Despite the efforts made to set up water institutions at Regional, Zonal and Woreda (district) levels, no significant achievement was recorded in the field. The aftermath of the civil war together with internal and external challenges epitomized the transition period had impinged on the water supply work.
This thesis testifies to the emergence of some socio-economic changes in the region. Yet, the slow progress of the water supply infrastructure work had stalled the socio-economic change that should have been registered through improved access to safe water supply. Despite the observable environmental degradation, the thesis argues that the retarded water supply work had nothing to do with the dearth of fresh water. While the trend shows steady growth of water consumption level across the three regimes, the conservation habit of the population remained low. / D.Litt. et Phil. (History)
