Hydro Electric Commission of Niagara Falls Ontario Scrapbook, 1936-1939, 1943-1951

Sir Adam Beck ( a London, Ontario manufacturer, Mayor and Conservative member of the provincial legislature) was a champion of municipal and provincial power ownership. Beck become the “Power Minister” and chairman of the Hydro-Electric Power Commission of Ontario which was the world’s first publicly owned utility. In 1925 the first unit of the Hydro Electric Power Commission’s Queenston Chippawa hydro-electric development on the Niagara River went into service. The station was renamed in 1950 as “Sir Adam Beck #1”. This marked the 25th anniversary of Beck’s death. This is one of 2 generating stations in Niagara Falls. There is also Adam Beck Plant #2. The Niagara generating stations supply one quarter of all power used in New York State and Ontario.Ontario Hydro has two water tunnels which traverse the entire City of Niagara Falls from the Village of Chippawa in the South to the Sir Adam Beck Hydro Electric Generating Stations in the North. Also they are in the process of building the third tunnel. In addition, Ontario Hydro has a 13.6 km open canal which traverses the entire City of Niagara Falls.

Measuring economies of horizontal and vertical integration in the US electric power industry:how costly is unbundling?

This research employs econometric analysis on a cross section of American electricity companies in order to study the cost implications associated with unbundling the operations of integrated companies into vertically and/or horizontally separated companies. Focusing on the representative sample average firm, we find that complete horizontal and vertical disintegration resulting in the creation of separate nuclear, conventional, and hydro electric generation companies as well as a separate firm distributing power to final consumers, results in a statistically significant 13.5 percent increase in costs. Maintaining a horizontally integrated generator producing nuclear, conventional, and hydro electric generation while imposing vertical separation by creating a stand alone distribution company, results in a lower but still substantial and statistically significant cost penalty amounting to an 8.1 % increase in costs relative to a fully integrated structure. As these results imply that a vertically separated but horizontally integrated generation firm would need to reduce the costs of generation by 11% just to recoup the cost increases associated with vertical separation, even the costs associated with just vertical unbundling are quite substantial. Our paper is also the first academic paper we are aware of that systematically considers the impact of generation mix on vertical, horizontal, and overall scope economies. As a result, we are able to demonstrate that the estimated cost of unbundling in the electricity sector is substantially influenced by generation mix. Thus, for example, we find evidence of strong vertical integration economies between nuclear and conventional generation, but little evidence for vertical integration benefits between hydro generation and the distribution of power. In contrast, we find strong evidence suggesting the presence of substantial horizontal integration economies associated with the joint production of hydro generation with nuclear and/or conventional fossil fuel generation. These results are significant because they indicate that the cost of unbundling the electricity sector will differ substantially in different systems, meaning that a blanket regulatory policy with regard to the appropriateness of vertical and horizontal unbundling is likely to be inappropriate.

Office of the City Clerk, St. Catharines Records, 1928-1974, n.d.

The site of present-day St. Catharines was settled by 3000 United Empire Loyalists at the end of the 18th century. From 1790, the settlement (then known as "The Twelve") grew as an agricultural community. St. Catharines was once referred to Shipman's Corners after Paul Shipman, owner of a tavern that was an important stagecoach transfer point. In 1815, leading businessman William Hamilton Merritt abandoned his wharf at Queenston and set up another at Shipman's Corners. He became involved in the construction and operation of several lumber and gristmills along Twelve Mile Creek. Shipman's Corners soon became the principal milling site of the eastern Niagara Peninsula. At about the same time, Merritt began to develop the salt springs that were discovered along the river which subsequently gave the village a reputation as a health resort. By this time St. Catharines was the official name of the village; the origin of the name remains obscure, but is thought to be named after Catharine Askin Robertson Hamilton, wife of the Hon. Robert Hamilton, a prominent businessman. Merritt devised a canal scheme from Lake Erie to Lake Ontario that would provide a more reliable water supply for the mills while at the same time function as a canal. He formed the Welland Canal Company, and construction took place from 1824 to 1829. The canal and the mills made St. Catharines the most important industrial centre in Niagara. By 1845, St. Catharines was incorporated as a town, with the town limits extending in 1854. Administrative and political functions were added to St. Catharines in 1862 when it became the county seat of Lincoln. In 1871, construction began on the third Welland Canal, which attracted additional population to the town. As a consequence of continual growth, the town limits were again extended. St. Catharines attained city status in 1876 with its larger population and area. Manufacturing became increasingly important in St. Catharines in the early 1900s with the abundance of hydro-electric power, and its location on important land and water routes. The large increase in population after the 1900s was mainly due to the continued industrialization and urbanization of the northern part of the city and the related expansion of business activity. The fourth Welland Canal was opened in 1932 as the third canal could no longer accommodate the larger ships. The post war years and the automobile brought great change to the urban form of St. Catharines. St. Catharines began to spread its boundaries in all directions with land being added five times during the 1950s. The Town of Merritton, Village of Port Dalhousie and Grantham Township were all incorporated as part of St. Catharines in 1961. In 1970 the Province of Ontario implemented a regional approach to deal with such issues as planning, pollution, transportation and services. As a result, Louth Township on the west side of the city was amalgamated, extending the city's boundary to Fifteen Mile Creek. With its current population of 131,989, St. Catharines has become the dominant centre of the Niagara region.

Development Planning at the State Level in India - A Case Study with Reference to Kerala, 1957-'84

This thesis entitled “Development planning at the state level in india a case study with reference to kerala1957-84.Planning in India is a concurrent subject with the Centre and the States having well-defined domains of jurisdiction with regard to planning functions and sources of resource mobilisation.The genesis of the lack of academic interest in state level planning is in the widely held belief that in the extent scheme of Centre-State economic relations, the states have little scope for initiative in planning.Both at the theoretical and empirical levels, Kerala has attached very great importance to planning.It has been the localeof wide and deep discussions on the various dimensions of planning.In Kerala's development process, the leading sector consists of social services such as education and public healthOne point that needs special emphasis in this regard is that the high demand for education in Kerala cannot be attributed to the Keralites' ‘unique urge‘ for education. Rather, it is related to the very high level of unemployment in the state (Kerala has the highest level of unemployment in the country.In resource allocation under the Five Year Plans, Kerala attached the highest weightage to power generation, hydro-electric projects being the major source of power in the state. Nearly one-fourth of the plan resources has been claimed by hydro-electric projects.In the agricultural sector, Kera1a's level of productive use of electric power is one of the lowest.As is evident.from above, planning in Kerala has not enabled us to solve the basic problems of the state. More 'scientific' planning in the sense of applying mre sophisticated planning techniques is obviously not the answer. It, on the contrary, consists of more fundamental changes some of which can be brought about through an effective use of measures well within the power of the State Government.

Szenarien zur zukünftigen Stromversorgung, kostenoptimierte Variationen zur Versorgung Europas und seiner Nachbarn mit Strom aus erneuerbaren Energien

Sowohl die Ressourcenproblematik als auch die drohenden Ausmaße der Klimaänderung lassen einen Umstieg auf andere Energiequellen langfristig unausweichlich erscheinen und mittelfristig als dringend geboten. Unabhängig von der Frage, auf welchem Niveau sich der Energiebedarf stabilisieren lässt, bleibt dabei zu klären, welche Möglichkeiten sich aus technischer und wirtschaftlicher Sicht in Zukunft zur Deckung unseres Energiebedarfs anbieten. Eine aussichtsreiche Option besteht in der Nutzung regenerativer Energien in ihrer ganzen Vielfalt. Die Arbeit "Szenarien zur zukünftigen Stromversorgung, kostenoptimierte Variationen zur Versorgung Europas und seiner Nachbarn mit Strom aus erneuerbaren Energien" konzentriert sich mit der Stromversorgung auf einen Teilaspekt der Energieversorgung, der zunehmend an Wichtigkeit gewinnt und als ein Schlüssel zur nachhaltigen Energieversorgung interpretiert werden kann. Die Stromversorgung ist heute weltweit für etwa die Hälfte des anthropogenen CO2-Ausstoßes verantwortlich. In dieser Arbeit wurden anhand verschiedener Szenarien Möglichkeiten einer weitgehend CO2–neutralen Stromversorgung für Europa und seine nähere Umgebung untersucht, wobei das Szenariogebiet etwa 1,1 Mrd. Einwohner und einen Stromverbrauch von knapp 4000 TWh/a umfasst. Dabei wurde untersucht, wie die Stromversorgung aufgebaut sein sollte, damit sie möglichst kostengünstig verwirklicht werden kann. Diese Frage wurde beispielsweise für Szenarien untersucht, in denen ausschließlich heute marktverfügbare Techniken berücksichtigt wurden. Auch der Einfluss der Nutzung einiger neuer Technologien, die bisher noch in Entwicklung sind, auf die optimale Gestaltung der Stromversorgung, wurde anhand einiger Beispiele untersucht. Die Konzeption der zukünftigen Stromversorgung sollte dabei nach Möglichkeit objektiven Kriterien gehorchen, die auch die Vergleichbarkeit verschiedener Versorgungsansätze gewährleisten. Dafür wurde ein Optimierungsansatz gewählt, mit dessen Hilfe sowohl bei der Konfiguration als auch beim rechnerischen Betrieb des Stromversorgungssystems weitgehend auf subjektive Entscheidungsprozesse verzichtet werden kann. Die Optimierung hatte zum Ziel, für die definierte möglichst realitätsnahe Versorgungsaufgabe den idealen Kraftwerks- und Leitungspark zu bestimmen, der eine kostenoptimale Stromversorgung gewährleistet. Als Erzeugungsoptionen werden dabei u.a. die Nutzung Regenerativer Energien durch Wasserkraftwerke, Windenergiekonverter, Fallwindkraftwerke, Biomassekraftwerke sowie solare und geothermische Kraftwerke berücksichtigt. Abhängig von den gewählten Randbedingungen ergaben sich dabei unterschiedliche Szenarien. Das Ziel der Arbeit war, mit Hilfe unterschiedlicher Szenarien eine breite Basis als Entscheidungsgrundlage für zukünftige politische Weichenstellungen zu schaffen. Die Szenarien zeigen Optionen für eine zukünftige Gestaltung der Stromversorgung auf, machen Auswirkungen verschiedener – auch politischer – Rahmenbedingungen deutlich und stellen so die geforderte Entscheidungsgrundlage bereit. Als Grundlage für die Erstellung der Szenarien mussten die verschiedenen Potentiale erneuerbarer Energien in hoher zeitlicher und räumlicher Auflösung ermittelt werden, mit denen es erstmals möglich war, die Fragen einer großräumigen regenerativen Stromversorgung ohne ungesicherte Annahmen anhand einer verlässlichen Datengrundlage anzugehen. Auch die Charakteristika der verschiedensten Energiewandlungs- und Transportsysteme mussten studiert werden und sind wie deren Kosten und die verschiedenen Potentiale in der vorliegenden Arbeit ausführlich diskutiert. Als Ausgangsszenario und Bezugspunkt dient ein konservatives Grundszenario. Hierbei handelt es sich um ein Szenario für eine Stromversorgung unter ausschließlicher Nutzung erneuerbarer Energien, die wiederum ausschließlich auf heute bereits entwickelte Technologien zurückgreift und dabei für alle Komponenten die heutigen Kosten zugrundelegt. Dieses Grundszenario ist dementsprechend auch als eine Art konservative Worst-Case-Abschätzung für unsere Zukunftsoptionen bei der regenerativen Stromversorgung zu verstehen. Als Ergebnis der Optimierung basiert die Stromversorgung beim Grundszenario zum größten Teil auf der Stromproduktion aus Windkraft. Biomasse und schon heute bestehende Wasserkraft übernehmen den überwiegenden Teil der Backup-Aufgaben innerhalb des – mit leistungsstarker HGÜ (Hochspannungs–Gleichstrom–Übertragung) verknüpften – Stromversorgungsgebiets. Die Stromgestehungskosten liegen mit 4,65 €ct / kWh sehr nahe am heute Üblichen. Sie liegen niedriger als die heutigen Preisen an der Strombörse. In allen Szenarien – außer relativ teuren, restriktiv ”dezentralen” unter Ausschluss großräumig länderübergreifenden Stromtransports – spielt der Stromtransport eine wichtige Rolle. Er wird genutzt, um Ausgleichseffekte bei der dargebotsabhängigen Stromproduktion aus erneuerbaren Quellen zu realisieren, gute kostengünstige Potentiale nutzbar zu machen und um die Speicherwasserkraft sowie die dezentral genutzte Biomasse mit ihrer Speicherfähigkeit für großräumige Backup-Aufgaben zu erschließen. Damit erweist sich der Stromtransport als einer der Schlüssel zu einer kostengünstigen Stromversorgung. Dies wiederum kann als Handlungsempfehlung bei politischen Weichenstellungen interpretiert werden, die demnach gezielt auf internationale Kooperation im Bereich der Nutzung erneuerbarer Energien setzen und insbesondere den großräumigen Stromtransport mit einbeziehen sollten. Die Szenarien stellen detaillierte und verlässliche Grundlagen für wichtige politische und technologische Zukunftsentscheidungen zur Verfügung. Sie zeigen, dass bei internationaler Kooperation selbst bei konservativen Annahmen eine rein regenerative Stromversorgung möglich ist, die wirtschaftlich ohne Probleme zu realisieren wäre und verweisen den Handlungsbedarf in den Bereich der Politik. Eine wesentliche Aufgabe der Politik läge darin, die internationale Kooperation zu organisieren und Instrumente für eine Umgestaltung der Stromversorgung zu entwickeln. Dabei kann davon ausgegangen werden, dass nicht nur ein sinnvoller Weg zu einer CO2–neutralen Stromversorgung beschritten würde, sondern sich darüber hinaus ausgezeichnete Entwicklungsperspektiven für die ärmeren Nachbarstaaten der EU und Europas eröffnen.

Efeitos de fragmentação de hábitat sobre a prevalência de parasitoses intestinais em alouatta belzebul (Primates, Platyrrhini) na Amazônia Oriental

Estudos parasitológicos em populações naturais de primatas neotropicais são relativamente raros, existindo poucos dados disponíveis sobre o guariba-de-mão-ruiva, Alouatta belzebul. No presente estudo, populações de A. belzebul foram amostradas em cinco locais na área do reservatório da Usina Hidrelétrica de Tucuruí no sudeste da Amazônia Brasileira, correspondendo à margem direita do Rio Tocantins. As áreas de coleta incluíram a floresta contínua e fragmentos de hábitats em ilhas, com tamanhos que variaram de 180 a 484 hectares. O principal objetivo deste estudo foi a avaliação dos efeitos da perturbação do hábitat sobre os padrões de infestação por endoparasitas. A densidade populacional foi estimada para cada ponto de coleta usando o método de transecção linear, que variou de 100-108 km percorridos por ponto. Amostras fecais foram coletadas de seis a quatorze grupos em cada local, com um total de 40-46 amostras por ponto (n = 212). As amostras fecais foram fixadas em MIF e observadas através de microscópio óptico, com aumentos de até 400x. A densidade populacional variou entre 66,4 e 191,5 indivíduos por km2. No total, 76,4% das amostras foram positivas para pelo menos uma espécie de endoparasita. Foram identificadas doze táxons de endoparasitas, oito de helmintos e cinco de protozoários. Amostras individuais apresentaram até cinco diferentes espécies de endoparasitas. Em cada local de coleta, o número de espécies identificadas variou entre seis e doze e as taxas de infecção ficaram entre 67,5% e 86%. Não foram encontrados padrões sistemáticos na diversidade de parasitas ou nas taxas de infecção em relação a variáveis como, tamanho de população, densidade ou fragmentação de hábitat. A diversidade e as taxas de infecção variaram mais entre os dois pontos de floresta contínua que nos locais fragmentados e, no geral, foram menores nos locais com menor densidade populacional. A única exceção foi o Trypanoxyuris mirtutus, um oxiurídeo bastante comum transmitido através do contato direto, para o qual foi encontrada uma correlação forte entre as taxas de infecção e a densidade populacional. No geral, foram encontradas poucas evidências capazes de sustentar a hipótese de que a fragmentação do hábitat tem um efeito sistemático nos padrões de infestação em A. belzebul. Contudo, recomenda-se a realização de mais estudos detalhados antes de se estabelecer conclusões definitivas.
