POLITICAL RISK IN FOREIGN DIRECT INVESTMENT IN THE RUSSIAN ELECTRIC POWER SECTOR

Russia approved ambitious reform plan for the electricity sector in 2001 including privatisation of the country’s huge thermal generation assets. So far the sector had suffered from power shortages, aging infrastructure, substantial electricity losses, and weak productivity and profitability numbers. There was obvious need for foreign investments and technologies. The reform was rather successful; the generation assets were privatised in auctions in 2007-2008 and three European energy companies, E.On, Enel and Fortum, invested in and obtained together over 10% of the Russian production assets. The novelty of these foreign investments serves unique object for the study. The political risk is involved in the FDI due to the industry’s social and economic importance. The research’s objective was to identify and analyse the political risk that foreign investors face in the Russian electricity sector. The research had qualitative study method and the empirical data was collected by interviewing. The research’s theoretical framework was based on the existing political risk theories and it focused to understand the Russian government in relation to the country’s stability and define both macro-level and micro-level sources of political risk for the foreign direct investments in the sector. The research concludes that the centralised and obscure political decision-making, economic constriction, high level of governmental control in economy and corruption form the country’s internal macro-level risk sources for the foreign investors in the sector. Additionally the retribution due to the companies’ home country actions, possible violent confrontations at the Russian borders and the currency instability are externally originated risk sources. In the electricity industry there is risk of tightened governmental control and increased regulation and taxation. Similarly the company-level risk sources link to the unreformed heating sector, bargaining with the authorities, diplomatic stress between host and home countries and to companies and government’s divergent perspective for the profit-making. The research stresses the foreign companies’ ability to cope with the characteristics of Russian political environment. In addition to frequent political and market risk assessment, the companies need to focus on currency protection against rouble’s rate fluctuation and actively build good company-citizenship in the country. Good relationship is needed with the Russian political authorities. The political risk identification and the research’s conclusive framework also enable political risk study assessments for other industries in Russia

Reuse of electric vehicle battery in uninterruptible power supply

Tässä diplomityössä tarkasteltiin Nissan Leaf -sähköauton käytetyn litiumakun soveltuvuutta UPS-varavirtalaitteen energialähteeksi. Kun akku on heikentynyt niin ettei sen kapasiteetti enää ole riittävä autokäyttöön, sitä voidaan kuitenkin vielä hyödyntää muissa sovelluksissa, kuten UPS-laitteessa. Työ sai alkunsa osana GreenDataNet-projektia, jossa pyritään kehittämään datakeskuksiin ympäristöä vähemmän kuormittavia ratkaisuja käyttämällä uusiutuvia energialähteitä, akkujen uusiokäytöllä, sekä energianhallinnan optimoinnilla. Työssä käytiin läpi akun ja sen ohjausjärjestelmän ominaisuuksia, kerrottiin UPS:in ohjelmistoon tehdyistä muutoksista sekä esitettiin testitulokset. Lopputuloksena todettiin akun sopivan muuten hyvin UPS-käyttöön, mutta vaadittu päivittäinen kennojännitteiden tasaus ja sen aiheuttama katkos energian saatavuuteen heikentää UPSin käyttövarmuutta kuorman suojauksessa. Lopussa esitettiin muutamia ehdotuksia tämän ongelman korjaamiseksi.

Energy Efficiency in Electrical Drive Systems: Technical potentials, barriers and policy approaches for small and medium industries in Ghana

Today industries and commerce in Ghana are facing enormous energy challenge. The pressure is on for industries to reduce energy consumption, lower carbon emissions and provide se-cured power supply. Industrial electric motor energy efficiency improvement is one of the most important tools to reduce global warming threat and reduce electricity bills. In order to develop a strategic industrial energy efficiency policy, it is therefore necessary to study the barriers that inhibit the implementation of cost – effective energy efficiency measures and the driving forces that promote the implementation. The aim of this thesis is to analyse the energy consumption pattern of electric motors, study factors that promote or inhibit energy efficiency improvements in EMDS and provide cost – effective solutions that improve energy efficiency to bridge the existing energy efficiency gap in the surveyed industries. The results from this thesis has revealed that, the existence of low energy efficiency in motor-driven systems in the surveyed industries were due to poor maintenance practices, absence of standards, power quality issues, lack of access to capital and limited awareness to the im-portance of energy efficiency improvements in EMDS. However, based on the results pre-sented in this thesis, a policy approach towards industrial SMEs should primarily include dis-counted or free energy audit in providing the industries with the necessary information on potential energy efficiency measures, practice best motor management programmes and estab-lish a minimum energy performance standard (MEPS) for motors imported into the country. The thesis has also shown that education and capacity development programmes, financial incentives and system optimization are effective means to promote energy efficiency in elec-tric motor – driven systems in industrial SMEs in Ghana

Kaksoiskäämitty hybridibussin kestomagneettiajomoottori

Tämä työ on tehty Lappeenrannan teknilliselle yliopistolle, joka on suunnitellut ja toteuttanut hybridibussin. Hybridibussin ajomoottorissa käytetään kaksoiskäämitystä, joka mahdollistaa bussin ajamisen vikatilanteessa, jossa toinen käämityksistä on epäkunnossa. Työn tavoitteena on selvittää, millainen kaksoiskäämitys toimii parhaiten tämän hybridibussin kestomagneettiajomoottorissa. Työssä tutustutaan ajomoottoreihin ja niiltä vaadittaviin ominaisuuksiin sekä vikasietoisiin sähkömoottoreihin. Tutkimuksessa löydettyihin vikasietoisiin ajomoottoreihin perustuen päädyttiin neljään kaksoiskäämitysvaihtoehtoon. Näitä kaksoiskäämityksiä tutkittiin FE-analyysiä hyödyntäen. Kaksoiskäämitysten toimintaa simuloitiin nimellis- ja vikatilanteessa. Simuloinnin tuloksista selvisi, että kaksoiskäämitys, jossa jokaisessa urassa oli puolet yhtä käämitystä ja puolet toista (kaksoiskäämitys 1), ei toiminut kunnolla nimellistilanteessa eikä vikatilanteessa. Suurin ongelma oli vikatilanteessa aiheutuva suuri oikosulkuvirta. Kaksoiskäämitys, jossa kaksi napaa oli samaa käämitystä (kaksoiskäämitys 2), toimi moitteettomasti nimellistilanteessa. Vikatilanteen toiminnassa kuitenkin havaittiin epäjaksollisuutta magneettivuontiheydessä, mikä on haitallista moottorin käynnille ja vaaraksi roottorille. Kaksoiskäämityksiä, joista ensimmäisessä oli neljäsosa konetta samaa käämitystä (kaksoiskäämitys 3) ja toisessa puolet koneesta samaa käämitystä (kaksoiskäämitys 4), tutkittiin vikatilanteessa vain magneettivuontiheyden osalta. Puolet ja puolet käämityn koneen osalta magneettivuontiheys osottautui epäjaksolliseksi kuten oli odotettu. Neljäsosiksi käämityn koneen magneettivuontiheys oli säännöllisen jaksollinen. Nimellispisteessä kaksoiskäämityksillä 3 ja 4 havaittiin suuri vääntöväre verrattuna kaksoiskäämityksiin 1 ja 2. Johtopäätöksenä kaksoiskäämitys 3 vaikuttaa lupaavalta, mikäli suuri nimellispisteen vääntöväre saadaan hallintaan käyttämällä uravinoutta staattorissa.

Buffalo, Brantford & Goderich Railway, County of Welland account book, 1853

The Buffalo and Brantford Railway Company was formed in 1850. The railway was renamed the Buffalo, Brantford & Goderich Railway in 1852 to reflect the plans to extend the line to Goderich. Financial problems led to a British group taking over the railway a few years later and the name was changed to the Buffalo & Lake Huron Railway. It was June 1858 before the line to Goderich was completed. Source: (http://brantford.library.on.ca/genealogy/railways.php#buffalo) March 8, 2010
