Fundraising and investor relations in social enterprise: Marketing your way out of the pioneer gap in African off-grid renewable energy

Social enterprises apply the best of business for the pursuit of social or environmental mission while also generating revenues. Globally, nearly 1,3 billion people lack access to electricity, as well as another billion having access to only low quality and infrequent electricity. Off-grid renewable energy, like solar, will increasingly have a key role in the solution of the energy access issue. The pioneer gap in off-grid renewable energy consists of financing (or funding) gaps and capacity gaps, to do with both the early stage of the enterprises in question, as well as the early stage of the whole industry. The gaps are emphasised by specific characteristics of off-grid renewable energy business models and the requirements of operating in bottom-of-the-pyramid markets. The marketing perspective to fundraising is chosen to uncover the possible role enterprises themselves have in bridging the pioneer gap. The purpose of this thesis is to study how social enterprises operating in off-grid renewable energy in Africa utilise marketing activities in their investor relations in bridging the pioneer gap. This main research question is divided into the following sub-questions:  How does the pioneer gap affect fundraising for these enterprises?  How are the funding needs for these enterprises characterised?  How do these enterprises build trust in their investor relations? The theoretic framework is built on relationship marketing and investor relations, with an emphasis on creation of trust. The research is conducted as a thematical case study. Primary data is gathered via semi-structured interviews with six solar energy companies and two accelerators. According to the findings, the main components affecting trust-creation are diminished information asymmetry and perceived risk, mission alignment as well as a personal fit or relationship with the investor. Therefore, an enterprise can utilise e.g. the following marketing activities in their investor relations to bridge the pioneer gap: ensuring investor material, the enterprise story and presenting of them is clear, concise and complete to “package” the enterprise as an investment; taking investor needs and motivations into account as well as utilising existing investors as ambassadors.

Lauhdevoimakapasiteetin ennenaikaisen poistumisen energiataloudelliset vaikutukset

Tässä diplomityössä on tutkittu lauhdekapasiteetin ennenaikaisen markkinoilta poistumisen energiataloudellisia vaikutuksia. Tarkastelu toteutettiin sähkömarkkinamallinnuksen avulla luomalla kaksi erilaista lauhdekapasiteettiskenaariota perustuen arvioituun lauhdekapasiteetin poistumiseen sekä vastavuoroisesti sen säilymiseen markkinoilla. Skenaarioiden vaikutuksia tutkittiin myös herkkyystarkasteluin ja tuloksia analysoitiin energiataloudellisesta näkökulmasta. Työn tavoitteena oli selvittää lauhdekapasiteetin ennenaikaisen poistumisen energiataloudellista kustannusta. Viime vuosien pitkittynyt talouden taantuma on hillinnyt kysynnän ennakoitua kehitystä johtaen alhaiseen sähkön markkinahintatasoon. Samalla tiukentuneet energiatuotannon ympäristövaatimukset asettavat investointirasitteita perinteisille voimalaitoksille heikentäen niiden taloudellisen kannattavuuden edellytyksiä. Markkinasähkön alhainen hintataso yhdessä investointirasitteiden kanssa asettaa haasteita etenkin usein rajatuotantomuotona toimiville lauhdelaitoksille. Alhaisen kannattavuuden seurauksena lauhdekapasiteettia arvioidaan poistuvan ennen teknisen käyttöiän täyttymistä markkinoilta merkittävästi lähivuosina. Kapasiteetin poistuminen kasvattaa oman tuotannon ja kysynnän välistä tehovajetta, minkä vuoksi sähköjärjestelmän nähdään tiukentuvan merkittävästi ennen rakenteilla olevan ydinvoimalaitoksen valmistumista. Työssä toteutettujen mallinnusten perusteella lauhdekapasiteetin väheneminen nostaa sähkön hintatasoa sekä lisää korkeiden hintapiikkien esiintymistä merkittävästi suhteessa korkeamman kapasiteetin tuloksiin. Sähköjärjestelmä on hyvin tiukka ennen rakenteilla olevan ydinvoimalaitoksen käyttöönottoa, minkä vuoksi lauhdekapasiteetin eroavaisuuksien vaikutukset ovat merkittävä etenkin poikkeuksellisen kylmänä vuotena. Lauhdekapasiteetin merkitys pienenee selvästi 2020-luvulla, kun oma tuotantokapasiteetti kasvaa. Työn tulosten perusteella lähivuosina alhaisemman lauhdekapasiteetin aiheuttama vuotuinen energiataloudellinen kustannus on huomattavasti korkeampi kuin laitosten kannattavan ylläpidon vaatima kustannus.

A cost-effective melting temperature assay for the detection of single-nucleotide polymorphism in the MBL2 gene of HIV-1-infected children

We report a fast (less than 3 h) and cost-effective melting temperature assay method for the detection of single-nucleotide polymorphisms in the MBL2 gene. The protocol, which is based on the Corbett Rotor Gene real time PCR platform and SYBR Green I chemistry, yielded, in the cohorts studied, sensitive (100%) and specific (100%) PCR amplification without the use of costly fluorophore-labeled probes or post-PCR manipulation. At the end of the PCR, the dissociation protocol included a slow heating from 60º to 95ºC in 0.2ºC steps, with an 8-s interval between steps. Melting curve profiles were obtained using the dissociation software of the Rotor Gene-3000 apparatus. Samples were analyzed in duplicate and in different PCR runs to test the reproducibility of this technique. No supplementary data handling is required to determine the MBL2 genotype. MBL2 genotyping performed on a cohort of 164 HIV-1-positive Brazilian children and 150 healthy controls, matched for age and sex and ethnic origin, yielded reproducible results confirmed by direct sequencing of the amplicon performed in blind. The three MBL2 variants (Arg52Cys, Gly54Asp, Gly57Glu) were grouped together and called allele 0, while the combination of three wild-type alleles was called allele A. The frequency of the A/A homozygotes was significantly higher among healthy controls (0.68) than in HIV-infected children (0.55; P = 0.0234) and the frequency of MBL2 0/0 homozygotes was higher among HIV-1-infected children than healthy controls (P = 0.0296). The 0 allele was significantly more frequent among the 164 HIV-1-infected children (0.29) than among the 150 healthy controls (0.18; P = 0.0032). Our data confirm the association between the presence of the mutated MBL2 allele (allele 0) and HIV-1 infection in perinatally exposed children. Our results are in agreement with the literature data which indicate that the presence of the allele 0 confers a relative risk of 1.37 for HIV-1 infection through vertical transmission.

Promoting Growth in the Use of Bioenergy in Europe by Converting Existing Coal-Fired Power Plants to Biomass

Repowering existing power plants by replacing coal with biomass might offer an interesting option to ease the transition from fossil fuels to renewable energy sources and promote a fur-ther expansion of bioenergy in Europe, on account of the potential to decrease greenhouse gas emissions, as well as other pollutants (SOx, NOx, etcetera). In addition, a great part of the appeal of repowering projects comes from the opportunity to reuse the vast existing invest-ment and infrastructure associated with coal-based power generation. Even so, only a limited number of experiences with repowering are found. Therefore, efforts are required to produce technical and scientific evidence to determine whether said technology might be considered feasible for its adoption within European conditions. A detailed evaluation of the technical and economic aspects of this technology constitutes a powerful tool for decision makers to define the energy future for Europe. To better illustrate this concept, a case study is analyzed. A Slovakian pulverized coal plant was used as the basis for determining the effects on perfor-mance, operation, maintenance and cost when fuel is shifted to biomass. It was found that biomass fuel properties play a crucial role in plant repowering. Furthermore, results demon-strate that this technology offers renewable energy with low pollutant emissions at the cost of reduced capacity, relatively high levelized cost of electricity and sometimes, a maintenance-intensive operation. Lastly, regardless of the fact that existing equipment can be reutilized for the most part, extensive additions/modifications may be required to ensure a safe operation and an acceptable performance.

Ydinvoiman säädettävyys laajamittaisesti sähköä varastoivassa energiajärjestelmässä

Tulevaisuudessa tuuli- ja aurinkovoiman osuus sähköntuotannosta tulee kasvamaan. Näiden uusiutuvien energiamuotojen tuotanto kuitenkin vaihtelee sääolosuhteiden mukaan. Tästä johtuen tarvitaan lisää säätövoimaa, jotta voidaan vastata sähkönkulutukseen tuuli- ja aurinkosähkön tuotannon laskiessa. Tässä työssä tarkastellaan mahdollisuutta toteuttaa sähkönkulutuksen ja tuotannon tasapainottaminen Suomessa sähkön varastoinnin avulla sekä ydinvoiman soveltuvuutta säätövoimaksi ja ydinsähkön varastoinnin kannattavuutta. Työssä vertaillaan mahdollisuuksia sähkön varastointiteknologioiksi, joista valitaan potentiaalisimmat vaihtoehdot kustannus- ja soveltuvuustarkasteluun. Varastointikapasiteetin tarvetta tarkastellaan Suomen nykyisen sähkönkulutuksen ja -tuotannon mukaan sekä tilanteessa, jossa tuuli- ja aurinkovoiman osuus on molemmilla 15 % kokonaistuotantokapasiteetista. Vanhempien sekä nykyaikaisten ydinvoimaloiden soveltuvuutta säätövoimaksi tarkastellaan laitosten säädettävyyden perusteella. Ydinvoimalaa on kuitenkin kannattavinta käyttää mahdollisimman suurella käyttökertoimella, joten tarkastelussa on myös mahdollisuus varastoida sähköä tilanteissa, joissa tuotantoa jouduttaisiin rajoittamaan. Varastointiteknologioiden ja eri skenaarioissa vaadittujen varastointikapasiteettien perusteella voidaan todeta, ettei sähkönkulutuksen ja -tuotannon tasapainottaminen sähkön varastoinnilla ole kannattavaa nykyisillä varastointikustannuksilla ja sähkön hinnoilla. Ydinvoiman voidaan todeta soveltuvan hyvin säätövoimaksi ominaisuuksien puolesta, mutta taloudellisesti se ei ole paras vaihtoehto. Ydinvoimalla tuotetun sähkön varastointi ei ole tällä hetkellä Suomessa kannattavaa matalien sähkön hintojen ja korkeiden varastointikustannusten vuoksi. Sähkön varastoinnista on mahdollista tulla kannattavaa 2020-luvulla. Tämä edellyttää Yhdysvaltojen energiaministeriön asettaman strategian toteutumista, jonka tavoitteena on varastoimalla tuotetun sähkön kustannusten saaminen alle 75 €/MWh.

Proposals for optimal network and battery characteristics are suggested.

Recovery boilers - history and future

Recovery boilers are built all over the world. The roots of recovery technology are longer than the roots of recovery boilers. But it wasn’t until the invention of recovery boilers before the Second World War that the pulping technology was revolutionalized. This led to long development of essentially the same type of equipment, culminating into units that are largest biofuel boilers in the world. Early recovery technology concentrated on chemical recovery as chemicals cost money and if one could recycle these chemicals then the profitability of pulp manufacture would improve. For pulp mills the significance of electricity generation from the recovery boiler was for long secondary. The most important design criterion for the recovery boiler was a high availability. The electricity generation in recovery boiler process can be increased by elevated main steam pressure and temperature or by higher black liquor dry solids as well as improving its steam cycle. This has been done in the modern Scandinavian units.

Production unit’s overhead cost allocation with activity-based costing in food industry enterprise

The main objective of this Master’s thesis is to develop a cost allocation model for a leading food industry company in Finland. The goal is to develop an allocation method for fixed overhead expenses produced in a specific production unit and create a plausible tracking system for product costs. The second objective is to construct an allocation model and modify the created model to be suited for other units as well. Costs, activities, drivers and appropriate allocation methods are studied. This thesis is started with literature review of existing theory of ABC, inspecting cost information and then conducting interviews with officials to get a general view of the requirements for the model to be constructed. The familiarization of the company started with becoming acquainted with the existing cost accounting methods. The main proposals for a new allocation model were revealed through interviews, which were utilized in setting targets for developing the new allocation method. As a result of this thesis, an Excel-based model is created based on the theoretical and empiric data. The new system is able to handle overhead costs in more detail improving the cost awareness, transparency in cost allocations and enhancing products’ cost structure. The improved cost awareness is received by selecting the best possible cost drivers for this situation. Also the capacity changes are taken into consideration, such as usage of practical or normal capacity instead of theoretical is suggested to apply. Also some recommendations for further development are made about capacity handling and cost collection.

Assessment of techno-economic use cases for small-scale island grids

The main objective of the study was to define the methodology for assessing the limits for application island grids instead of interconnecting with existing grid infrastructure. The model for simulation of grid extension distance and levelised cost of electricity has been developed and validated by the case study in Finland. Thereafter, sensitivities of the application limits were examined with the respect to operational environment, load conditions, supply security and geographical location. Finally, recommendations for the small-scale rural electrification projects in the market economy environment have been proposed.

Cost-effective analysis of different algorithms for the diagnosis of hepatitis C virus infection

We compared the cost-benefit of two algorithms, recently proposed by the Centers for Disease Control and Prevention, USA, with the conventional one, the most appropriate for the diagnosis of hepatitis C virus (HCV) infection in the Brazilian population. Serum samples were obtained from 517 ELISA-positive or -inconclusive blood donors who had returned to Fundação Pró-Sangue/Hemocentro de São Paulo to confirm previous results. Algorithm A was based on signal-to-cut-off (s/co) ratio of ELISA anti-HCV samples that show s/co ratio ³95% concordance with immunoblot (IB) positivity. For algorithm B, reflex nucleic acid amplification testing by PCR was required for ELISA-positive or -inconclusive samples and IB for PCR-negative samples. For algorithm C, all positive or inconclusive ELISA samples were submitted to IB. We observed a similar rate of positive results with the three algorithms: 287, 287, and 285 for A, B, and C, respectively, and 283 were concordant with one another. Indeterminate results from algorithms A and C were elucidated by PCR (expanded algorithm) which detected two more positive samples. The estimated cost of algorithms A and B was US$21,299.39 and US$32,397.40, respectively, which were 43.5 and 14.0% more economic than C (US$37,673.79). The cost can vary according to the technique used. We conclude that both algorithms A and B are suitable for diagnosing HCV infection in the Brazilian population. Furthermore, algorithm A is the more practical and economical one since it requires supplemental tests for only 54% of the samples. Algorithm B provides early information about the presence of viremia.

Photodynamic antimicrobial chemotherapy (PACT) for the treatment of malaria, leishmaniasis and trypanosomiasis

A photodynamic effect occurs when photosensitiser molecules absorb light and dissipate the absorbed energy by transferring it to biological acceptors (usually oxygen), generating an excess of reactive species that are able to force cells into death pathways. Several tropical diseases present physiopathological aspects that are accessible to the application of a photosensitiser and local illumination. In addition, disease may be transmitted through infected blood donations, and many of the aetiological agents associated with tropical diseases have been shown to be susceptible to the photodynamic approach. However, there has been no systematic investigation of the application of photoantimicrobial agents in the various presentations, whether to human disease or to the disinfection of blood products or even as photo-insecticides. We aim in this review to report the advances in the photoantimicrobial approach that are beneficial to the field of anti-parasite therapy and also have the potential to facilitate the development of low-cost/high-efficiency protocols for underserved populations.

Improving Cost-Efficiency and Reducing Environmental Impacts of Intermodal Transportation with Dry Port Concept – Major Rail Transport Corridor in Baltic Sea Region

Transportation plays a major role in the gross domestic product of various nations. There are, however, many obstacles hindering the transportation sector. Cost-efficiency along with proper delivery times, high frequency and reliability are not a straightforward task. Furthermore, environmental friendliness has increased the importance of the whole transportation sector. This development will change roles inside the transportation sector. Even now, but especially in the future, decisions regarding the transportation sector will be partly based on emission levels and other externalities originating from transportation in addition to pure transportation costs. There are different factors, which could have an impact on the transportation sector. IMO’s sulphur regulation is estimated to increase the costs of short sea shipping in the Baltic Sea. Price development of energy could change the roles of different transport modes. Higher awareness of the environmental impacts originating from transportation could also have an impact on the price level of more polluting transport modes. According to earlier research, increased inland transportation, modal shift and slowsteaming can be possible results of these changes in the transportation sector. Possible changes in the transportation sector and ways to settle potential obstacles are studied in this dissertation. Furthermore, means to improve cost-efficiency and to decrease environmental impacts originating from transportation are researched. Hypothetical Finnish dry port network and Rail Baltica transport corridor are studied in this dissertation. Benefits and disadvantages are studied with different methodologies. These include gravitational models, which were optimized with linear integer programming, discrete-event and system dynamics simulation, an interview study and a case study. Geographical focus is on the Baltic Sea Region, but the results can be adapted to other geographical locations with discretion. Results indicate that the dry port concept has benefits, but optimization regarding the location and the amount of dry ports plays an important role. In addition, the utilization of dry ports for freight transportation should be carefully operated, since only a certain amount of total freight volume can be cost-efficiently transported through dry ports. If dry ports are created and located without proper planning, they could actually increase transportation costs and delivery times of the whole transportation system. With an optimized dry port network, transportation costs can be lowered in Finland with three to five dry ports. Environmental impacts can be lowered with up to nine dry ports. If more dry ports are added to the system, the benefits become very minor, i.e. payback time of investments becomes extremely long. Furthermore, dry port network could support major transport corridors such as Rail Baltica. Based on an analysis of statistics and interview study, there could be enough freight volume available for Rail Baltica, especially, if North-West Russia is part of the Northern end of the corridor. Transit traffic to and from Russia (especially through the Baltic States) plays a large role. It could be possible to increase transit traffic through Finland by connecting the potential Finnish dry port network and the studied transport corridor. Additionally, sulphur emission regulation is assumed to increase the attractiveness of Rail Baltica in the year 2015. Part of the transit traffic could be rerouted along Rail Baltica instead of the Baltic Sea, since the price level of sea transport could increase due to the sulphur regulation. Both, the hypothetical Finnish dry port network and Rail Baltica transport corridor could benefit each other. The dry port network could gain more market share from Russia, but also from Central Europe, which is the other end of Rail Baltica. In addition, further Eastern countries could also be connected to achieve higher potential freight volume by rail.

Cross-border transmission capacity development – Experiences from the Nordic electricity markets

The liberalisation of the wholesale electricity markets has been considered an efficient way to organise the markets. In Europe, the target is to liberalise and integrate the common European electricity markets. However, insufficient transmission capacity between the market areas hampers the integration, and therefore, new investments are required. Again, massive transmission capacity investments are not usually easy to carry through. This doctoral dissertation aims at elaborating on critical determinants required to deliver the necessary transmission capacity investments. The Nordic electricity market is used as an illustrative example. This study suggests that changes in the governance structure have affected the delivery of Nordic cross-border investments. In addition, the impacts of not fully delivered investments are studied in this doctoral dissertation. An insufficient transmission network can degrade the market uniformity and may also cause a need to split the market into smaller submarkets. This may have financial impacts on market actors when the targeted efficient sharing of resources is not met and even encourage gaming. The research methods applied in this doctoral dissertation are mainly empirical ranging from a Delphi study to case studies and numerical calculations.

Vahdon keskustan sähkönjakeluverkon saneeraussuunnitelma

Vuoden 2013 sähkömarkkinalain uudistuksen myötä verkonhaltijoiden tulee varautua suurhäiriötilanteisiin aiempaa tehokkaammin. Lain toimitusvarmuusvaatimusten täyttäminen vaatii sähköverkkoyhtiöiltä entistä suurempia investointimääriä nopeassa aikataulussa. Caruna Oy investoi vuosittain noin 100 miljoonaa euroa säävarman verkon kehittämiseen ja rakentamiseen. Eltel Networks Oy toimii Carunan pääurakoitsijana useissa saneerausprojekteissa muun muassa Satakunnan ja Lounais-Suomen alueilla. Diplomityö tehtiin Eltel Networks Oy:lle ja tavoitteena oli laatia saneeraussuunnitelma Carunan Vahdon keskustan sähkönjakeluverkkoon sekä kehittää Eltelin suunnitteluprosessia Vahdon case-projektin avulla. Nykyverkon ongelmakohdiksi osoittautuivat käyttöikänsä päähän tulleet tai lähivuosina tulevat verkkokomponentit, verkon alhainen nykykäyttöarvo sekä korkeat keskeytyskustannukset. Suunnitellun verkon nykykäyttöarvo yli kaksinkertaistui nykyverkon arvosta, verkon keski-ikä pieneni seitsemällä vuodella ja keskeytyskustannukset pienenivät yli puolella. Case-projektin aikana suunnitteluprosessissa ilmeni useita kehityskohteita. Esimerkiksi kartta-aineistoja ja ilmakuvia kannattaisi hyödyntää monipuolisemmin suunnittelussa ja ohjemuutosten täytäntöönpanoajankohta tulisi määrittää ohjeen tärkeyden mukaan. Vierekkäisille suunnitteluprojekteille kannattaa hakea jatkossa esimerkiksi yhteiset ELY- ja AVI-luvat erillisten lupahakemusten sijaan, koska se vähentää suunnittelijoiden työmäärää ja nopeuttaa hakuprosessia. Suunnittelijoiden yhteistyötä kannattaa laajentaa niin lupahakemusten, sopimusten laadinnan kuin koko prosessin kattavaksi, koska yhteistyö vähentää virheiden määrää ja nopeuttaa suunnitteluprosessia. Yhteistyöllä suunnittelu voidaan toteuttaa nopeammin laadusta tinkimättä.
