Localização de usinas termoelétricas utilizando Sistema de Informação Geográfica e métodos de decisão multicritério

No setor de energia elétrica, a área que se dedica ao estudo da inserção de novos parques geradores de energia no sistema é denominada planejamento da expansão da geração. Nesta área, as decisões de localização e instalação de novas usinas devem ser amplamente analisadas, a fim de se obter os diversos cenários proporcionados pelas alternativas geradas. Por uma série de fatores, o sistema de geração elétrico brasileiro, com predominância hidroelétrica, tende a ser gradualmente alterada pela inserção de usinas termoelétricas (UTEs). O problema de localização de UTEs envolve um grande número de variáveis através do qual deve ser possível analisar a importância e contribuição de cada uma. O objetivo geral deste trabalho é o desenvolvimento de um modelo de localização de usinas termoelétricas, aqui denominado SIGTE (Sistema de Informação Geográfica para Geração Termoelétrica), o qual integra as funcionalidades das ferramentas SIGs (Sistemas de Informação Geográfica) e dos métodos de decisão multicritério. A partir de uma visão global da área estudada, as componentes espaciais do problema (localização dos municípios, tipos de transporte, linhas de transmissão de diferentes tensões, áreas de preservação ambiental, etc.) podem ter uma representação mais próxima da realidade e critérios ambientais podem ser incluídos na análise. Além disso, o SIGTE permite a inserção de novas variáveis de decisão sem prejuízo da abordagem. O modelo desenvolvido foi aplicado para a realidade do Estado de São Paulo, mas deixando claro a viabilidade de uso do modelo para outro sistema ou região, com a devida atualização dos bancos de dados correspondentes. Este modelo é designado para auxiliar empreendedores que venham a ter interesse em construir uma usina ou órgãos governamentais que possuem a função de avaliar e deferir ou não a licença de instalação e operação de usinas.

Evaluation of semi-passive treatment technologies for septic lagoon capacity expansion

In Canada, increases in rural development has led to a growing need to effectively manage the resulting municipal and city sewage without the addition of significant cost- and energy- expending infrastructure. Storring Septic Service Limited is a family-owned, licensed wastewater treatment facility located in eastern Ontario. It makes use of a passive waste stabilization pond system to treat and dispose of waste and wastewater in an environmentally responsible manner. Storring Septic, like many other similar small-scale wastewater treatment facilities across Canada, has the potential to act as a sustainable eco-engineered facility that municipalities and service providers could utilize to manage and dispose of their wastewater. However, it is of concern that the substantial inclusion of third party material could be detrimental to the stability and robustness of the pond system. In order to augment the capacity of the current facility, and ensure it remains a self-sustaining system with the capacity to safely accept septage from other sewage haulers, it was hypothesized that pond effluent treatment could be further enhanced through the incorporation of one of three different technology solutions, which would allow the reduction of wastewater quality parameters below existing regulatory effluent discharge limits put in place by Ontario’s Ministry of the Environment and Climate Change (MOECC). Two of these solutions make use of biofilm technologies in order to enhance the removal of wastewater parameters of interest, and the third utilizes the natural water filtration capabilities of zebra mussels. Pilot-scale testing investigated the effects of each of these technologies on treatment performance under both cold and warm weather operation. This research aimed to understand the important mechanisms behind biological filtration methods in order to choose and optimize the best treatment strategy for full-scale testing and implementation. In doing so, a recommendation matrix was elaborated provided with the potential to be used as a universal operational strategy for wastewater treatment facilities located in environments of similar climate and ecology.

An Academic Medical Center's Expansion to the European Union: A Case Study of UPMC's Joint Projects in Italy and Ireland. Pittsburgh Papers on the European Union Vol. 3, June 2014

This case study examines the expansion of the University of Pittsburgh Medical Center (UPMC) to Italy and Ireland in the European Union. The authors use international business theory to help understand why US Academic Medical Centers (AMCs) are beginning to go abroad and, through semistructured interviews with UPMC officials, they examine the market entry issues UPMC faced when expanding to Italy and Ireland. The authors also explain why UPMC’s first successful foreign ventures took place in the European Union. They conclude with comments on several of the strategic issues that AMCs should address if they wish to successfully expand overseas.

Gazprom's expansion in the EU - co-operation or domination? OSW Report, April 2008

The energy sector, especially with regard to natural gas trade, is one of the key areas of co-operation between the EU and Russia. However, the character of this co-operation has given rise to increasing doubts both in Brussels and among the EU member states. The questions have emerged whether this co-operation does not make the EU excessively dependent on Russian energy supplies, and whether Gazprom's presence in the EU will not allow Moscow to interfere in the proces of devising the EU energy policy. This report is intended to present the factual base and data necessary to provide accurate answers to the foregoing questions. The first part of the report presents the scope and character of Gazprom's economic presence in the EU member states. The second part shows the presence of the EU investors in Russia. The data presented has been provided by the International Energy Agency, European Commission, the Central Bank of Russia and the Russian Federal State Statistics Service. Some of the data is the result of calculations made by the Centre for Eastern Studies' experts who were basing on the data provided by energy companies, the specialist press and news agencies.

Gazprom's expansion in the EU: co-operation or domination? OSW Report, October 2009

The energy sector, especially with regard to the gas trade, is one of the key areas of co-operation between the EU and Russia. However, the form this co-operation has taken has been giving rise to some concern, both in Brussels and in the EU member states. Questions arise as to whether the EU has not become excessively dependent on Russia for energy, and whether the presence of the Russian gas monopoly in the EU does not enable Russian interference with the development of EU energy policy. The objective of this series of OSW reports (for the previous edition,see Gazprom’s expansion in the EU: co-operation or domination? April 2008 – pdf 1.2 MB) is to provide facts which will permit an accurat answer to these questions to be formulated.

Gazprom’s expansion in the EU: co-operation or domination? OSW Report, October 2009. Second edition, revised

Introduction. The energy sector, especially with regard to the gas trade, is one of the key areas of co-operation between the EU and Russia. However, the form this co-operation has taken has been giving rise to some concern, both in Brussels and in the EU member states. Questions arise as to whether the EU has not become excessively dependent on Russia for energy, and whether the presence of the Russian gas monopoly in the EU does not enable Russian interference with the development of EU energy policy. The objective of this series of OSW reports (for the previous edition,see Gazprom’s expansion in the EU: co-operation or domination? April 2008 – pdf 1.2 MB) is to provide facts which will permit an accurat answer to these questions to be formulated. Over the course of last year, two new factors strongly affected Gazprom’s capability to operate on the EU market. One was the ongoing global economic crisis, which has depressed demand for gas both in Russia and in Europe. Gazprom has cut both its own production and the quantities of gas it purchases from the Central Asian states, and the decrease in export revenues has forced the company to modify some of its current investment plans. Less demand for gas and the need to reduce production are also having a positive impact – the Russian company is likely to avoid the difficulties in meeting all of its export commitments which, only a year or so ago, it was expected to experience. The other factor affecting Gazprom’s expansion in Europe is the observed radicalisation of the rhetoric and actions of both the company itself and of the Russian authorities with regard to the gas sector as broadly understood. The gas crisis between Russia and Ukraine in January 2009, which resulted in a two-week interruption of gas supplies from Russia to Europe via Ukraine, was the most prominent example of this radicalisation. The hardening of rhetoric in the ongoing energy talks with the EU and other actors, and increased political and business activities designed to promote Russian gas interests in Europe, in particular the lobbying for the Nord Stream and South Stream projects, are further signs of this shift in tone. These issues raise the question of whether, and to what extent, the current condition of Gazprom’s finance will permit the company to implement the infrastructural projects it has been endorsing and its other investment plans in Europe. Another important question is whether the currently observed changes in how Gazprom operates will take on a more permanent character, and what consequences this will have for the European Union. The first part of this report discusses Gazprom’s production and export potential. The second comprehensively presents the scope and nature of Gazprom’s economic presence in the EU member states. Finally, the third part presents the Russian company’s methods of operation on foreign markets. The data presented in the report come mainly from the statistics of the International Energy Agency, the European Commission and Gazprom, as well as the Central Bank of Russia and the Russian Statistical Office. The figures presented here also include proprietary calculations by the OSW based on figures disclosed by energy companies and reports by professional press and news agencies.

Ukraine, Belarus and Moldova and the Chinese economic expansion in Eastern Europe. OSW Commentary No. 79, 2012-05-28

The countries of Eastern European and China have been increasingly interested in deepening bilateral contacts over the past few years. In the case of Ukraine, Belarus and Moldova this has been caused by the bad economic situation which was in part caused by the consequences of the global economic crisis of 2008 and the desire to establish closer political relations with a country whose significance on the international arena is continually growing. Each of these countries has different expectations regarding the scale and the nature of co-operation with China. Chisinau wishes only to boost trade, whereas in Minsk and Kyiv, Beijing is also presented as a strategic partner whose investments may not only help the indebted economies recover but also strengthen the position of these countries in their dealings with the EU, and especially with Russia. Beijing sees co-operation with these countries in differently, and its offer is much more modest than Belarus and Ukraine are expecting. Eastern Europe is one of the last parts of the world with which China is activating its co-operation. This is not a priority region for Beijing. China wants to derive economic benefits and to diversify the markets on which it invests its financial surplus, and it does not intend to extend its political dialogue with Ukraine, Belarus and Moldova beyond the framework which determines its economic interests. The main reason for this is the nature of relations between Russia and China. Beijing sees its partnership with Moscow as more beneficial, and will not offer these countries support in their relations with Russia since in its opinion they belong to Russia’s sphere of influence. Minsk and Kyiv are pinning too much hope on their co-operation with Beijing, while China offers no real counterbalance to the Russian and EU influences in these countries. Nevertheless, it should be expected that China will capitalise on the beneficial political climate in Ukraine, Belarus and Moldova to reinforce its influence in a region whose location will facilitate its expansion to the EU and the Customs Union markets. In the medium term, Beijing may become a major economic player in Eastern Europe. In a decade’s time this may translate into political influence. Meanwhile, in the short term, China’s financial engagement in Ukraine, Belarus and Moldova will contribute to increasing the debts and deepening the foreign trade deficits of these countries.

Nord Stream expansion: what does it mean for Europe? EPC Commentary, 2 July 2015

Two announcements in sequence have shaken the energy debate on 18 and 19 June. Gazprom announced the signature of a Memorandum of Understanding with Shell, Exon and OMV for the construction of strings 3 and 4 of Nord Stream, aiming at doubling the current 55 bcm capacity of the corridor running in the Baltic sea bed and connecting the Russian terminal of Vyborg to Germany. On the day after, a €2 bn deal between Russia and Greece was signed for extending the Turkish Stream project into Greek territory. ...
