Impact of wind power generation on the electricity supply industry

The objective of this dissertation is to investigate the effect wind energy has on the Electricity Supply Industry in Ireland. Wind power generation is a source of renewable energy that is in abundant supply in Ireland and is fast becoming a resource that Ireland is depending on as a diverse and secure of supply of energy. However, wind is an intermittent resource and coupled with a variable demand, there are integration issues with balancing demand and supply effectively. To maintain a secure supply of electricity to customers, it is necessary that wind power has an operational reserve to ensure appropriate backup for situations where there is low wind but high demand. This dissertation examines the affect of this integration by comparing wind generation to that of conventional generation in the national grid. This is done to ascertain the cost benefits of wind power generation against a scenario with no wind generation. Then, the analysis examines to see if wind power can meet the pillars of sustainability. This entails looking at wind in a practical scenario to observe how it meets these pillars under the criteria of environmental responsibility, displacement of conventional fuel, cost competitiveness and security of supply.

The importance and accuracy of wind power forecasts

Due to the global crisis o f climate change many countries throughout the world are installing the renewable energy o f wind power into their electricity system. Wind energy causes complications when it is being integrated into the electricity system due its intermittent nature. Additionally winds intennittency can result in penalties being enforced due to the deregulation in the electricity market. Wind power forecasting can play a pivotal role to ease the integration o f wind energy. Wind power forecasts at 24 and 48 hours ahead of time are deemed the most crucial for determining an appropriate balance on the power system. In the electricity market wind power forecasts can also assist market participants in terms o f applying a suitable bidding strategy, unit commitment or have an impact on the value o f the spot price. For these reasons this study investigates the importance o f wind power forecasts for such players as the Transmission System Operators (TSOs) and Independent Power Producers (IPPs). Investigation in this study is also conducted into the impacts that wind power forecasts can have on the electricity market in relation to bidding strategies, spot price and unit commitment by examining various case studies. The results o f these case studies portray a clear and insightful indication o f the significance o f availing from the information available from wind power forecasts. The accuracy o f a particular wind power forecast is also explored. Data from a wind power forecast is examined in the circumstances o f both 24 and 48 hour forecasts. The accuracy o f the wind power forecasts are displayed through a variety o f statistical approaches. The results o f the investigation can assist market participants taking part in the electricity pool and also provides a platform that can be applied to any forecast when attempting to define its accuracy. This study contributes significantly to the knowledge in the area o f wind power forecasts by explaining the importance o f wind power forecasting within the energy sector. It innovativeness and uniqueness lies in determining the accuracy o f a particular wind power forecast that was previously unknown.

To determine if the ‘NIMBY’ phenomenon explains the slow progress of wind farm development or do institutional factors need to be taken in to consideration?

The threats posed by climate change are placing governments under increasing pressure to meet electricity demand from low carbon sources. Wind energy has been has been identified as one of the main technologies to help in meeting these demands. The public in general favour wind energy yet proposed targets for generation capacity lag behind proposed goals. The N IM B Y phenomenon has been suggested as one of the reasons why we are behind our wind generation capacity targets. It is a common mistake to take general support for granted and expect the public to support developments when confronted with them in their local area. In many cases it is not unheard of that governing bodies whether social, political, regulatory, environmental, or cultural can overrule general public support and halt developments. Motives to halt developments will vary depending on the institutional body involved. The problem with the term N IM B Y is that it is too basic a term to describe the broad spectrum of complex motives that various institutions including the public may have against a development. This research focuses on a case study where the developer had major problems with the local county council and its wind energy policies when he was erecting a wind turbine despite having gained planning permission. A survey questionnaire was also used as part o f the research to seek the perception a rural community had on wind energy. The research findings and results are discussed with respect to the literature review highlighting a general public support for wind energy and the influence institutional bodies have over the progress of developments.

The Irish pub as a third place : a sociological exploration of people, place and identity

There is considerable interest in alcohol in Irish society, yet minimal sociologcial understanding of its consumption, particularly of the sites where most drinking occurs: the country's 8750 pubs. Despite widespread public discussions on the role of the pub, there is scant social science evidence to better inform debate. Pubs are central to Irish community and are key sites of social interaction. American sociologist Ray Oldenburg has argued that "third places" (neither workplace nor home) are crucial to the maintenance of the community and the enhancement of social capital. According to Oldenburg, the role of the third place in the community is to provide continuity, regularity, a sense of place - all of which conceptually contribute to the construction of the self, the projection of the self within the public sphere, the distribution of social capital and the generation of a collective identity. The pub is the archetypal third place, but Oldenburg is concerned that modern pubs are less able to provide this vital function. Social scientists have suggested that community is in a state of fragmentation and decline due to changes in modes of social interaction and a decrease in shared spaces, resulting in a weakened connection to place. Community without propinquity has been characterised by social alienation, fragmentation and what Oldenburg refers to as the "problem of place" (13). Third places, and thus the Irish pub, have been particularly affected. In order to increase the sociological knowledge of the pub in Ireland, this project critically engages with the pub to assess the importance that public drinking houses have in the everyday. Moreover, this research sets out to investigate the people/place relationship using the pub as an investigative lens and examine the ways in which people shape place, place shapes people and how that relationship is implicated in the construction of irish identities. Furthermore, this is also an articulation of a cultural shift within Ireland and Irish places whose effects are deep and multi-layered. This project aims to explore the development of the contemporary geography of identity as the irish pub as a third place is transformed or disappears from the social landscape.

An Investigation into Irish State patronage of the visual arts.

The focus of this research is in ascertaining how and why the Irish state patronises the visual arts. The framework that the state puts in place for the support of the arts influences the creation of art. The initial standpoint from which to evaluate the system is founded on the belief that art is of social good. The second source of belief is in the necessity for an autonomous setting in which it can be created. These two beliefs underpin state patronage of the arts in contemporary society. Therefore they have to be examined carefully in order to see if they hold up. This requires an investigation into the formation of value. This is undertaken by looking into the social development of western society and its influence on the placement of arts value. Establishing how arts value to society is defined provides a means by which to investigate the manner in which the state patronises the visual arts. Two case studies provide the evidence in how the state supports the arts and why it chooses to do so. The Irish Museum of Modem Art is used as an example of the state’s role in the maintenance of the canon of art. The second case study looks at the work being done by Breaking Ground. Breaking Ground is an extensive art project as an element of the regeneration process happening in Ballymun funded by the state. It provides and insight into how the state utilises art in the unification of a social group.

Investigation into the feasibility of a West of Ireland Pumped Storage System

Ireland’s remote position on the tip of Europe ensures that the country is vulnerable to uncertainty of supply. The reliance on conventional sources of electricity has ensured that escalated prices and high carbon emissions have been witnessed whilst opportunities that inherent resources provide, such as the wind, have not been capitalised upon. The intermittent nature of the wind make it difficult to maximise its potential as in many cases the highest wind speeds are highest when demand is low. The West of Ireland’s combination of wind speeds and unique topography makes it suitable for and innovative wind powered pumped storage system, which can essentially regulate the wind generated electricity and integrate further penetration of renewable energy. In addition, its location along the Atlantic Ocean provides further scope for innovation as seawater can be integrated into the system design. The construction of such an unprecedented project in combination with increased interconnectors has the potential to make Ireland a rechargeable battery for Europe. However, such ambitious plans are at the very early stages and are in direct contrast to current events in the Irish energy market. This study focuses on the feasibility of West of Ireland pumped storage systems. Entailed within this is an extensive desk study, a detailed site selection process and a feasibility study of grid connection. To increase opportunities to identify the best possible site, the feasibility study was focused on the Galway and Mayo areas solely.
