Change of Electricity Distribution Industry: Drivers and Opening Business Opportunities

As a result of the recent regulatory amendments and other development trends in the electricity distribution business, the sector is currently witnessing radical restructuring that will eventually impact the business logics of the sector. This report represents upcoming changes in the electricity distribution industry and concentrates on the factors that are expected to be the most fundamental ones. Electricity network companies nowadays struggle with legislative and regulatory requirements that focus on both the operational efficiency and the reliability of electricity distribution networks. The forces that have an impact on the distribution network companies can be put into three main categories that define the transformation at a general level. Those are: (1) a requirement for a more functional marketplace for energy, (2) environmental aspects (combating climate change etc.), and (3) a strongly emphasized requirement for the security of energy supply. The first point arises from the legislators’ attempt to increase competition in electricity retail markets, the second one concerns both environmental protection and human safety issues, and the third one indicates societies’ reduced willingness to accept interruptions in electricity supply. In the future, regulation of electricity distribution business may lower the threshold for building more weather-resistant networks, which in turn means increased underground cabling. This development pattern is reinforced by tightening safety and environmental regulations that ultimately make the overhead lines expensive to build and maintain. The changes will require new approaches particularly in network planning, construction, and maintenance. The concept for planning, constructing, and maintaining cable networks is necessary because the interdependencies between network operations are strong, in other words, the nature of the operation requires a linkage to other operations.

Theoretical background for market emergence framework : Case: Electricity Distribution Industry

Both the competitive environment and the internal structure of an industrial organization are typically included in the processes which describe the strategic management processes of the firm, but less attention has been paid to the interdependence between these views. Therefore, this research focuses on explaining the particular conditions of an industry change, which lead managers to realign the firm in respect of its environment for generating competitive advantage. The research question that directs the development of the theoretical framework is: Why do firms outsource some of their functions? The three general stages of the analysis are related to the following research topics: (i) understanding forces that shape the industry, (ii) estimating the impacts of transforming customer preferences, rivalry, and changing capability bases on the relevance of existing assets and activities, and emergence of new business models, and (iii) developing optional structures for future value chains and understanding general boundaries for market emergence. The defined research setting contributes to the managerial research questions “Why do firms reorganize their value chains?”, “Why and how are decisions made?” Combining Transaction Cost Economics (TCE) and Resource-Based View (RBV) within an integrated framework makes it possible to evaluate the two dimensions of a company’s resources, namely the strategic value and transferability. The final decision of restructuring will be made based on an analysis of the actual business potential of the outsourcing, where benefits and risks are evaluated. The firm focuses on the risk of opportunism, hold-up problems, pricing, and opportunities to reach a complete contract, and finally on the direct benefits and risks for financial performance. The supplier analyzes the business potential of an activity outside the specific customer, the amount of customer-specific investments, the service provider’s competitive position, abilities to revenue gains in generic segments, and long-term dependence on the customer.

Prognosis of after spot volumes at the Scandinavian electricity market

The Thesis is dedicated to development of an operative tool to support decision making in after spot trading on the Nordic electricity market. The basics of the Nordic electricity market, trading mechanisms on the spot and after spot markets are presented in the Thesis. Mathematical equations that describe electricity balance condition in the power system are offered. The main driving factors that impact deviation of actual electricity balance from the scheduled one (object) in the power system have been explored and mathematically defined. The behavioral model of the object and principal trends in change of state of the object under an impact of the driving factors are determined with the help of regression analysis made in Microsoft Office Excel. The behavioral model gives an indication for the total regulation volume (Elbas trades volume, volume of regulation market, balance power) for a certain hour that serves as the base input in estimating prices on the after spot markets. Proposals for development of methodologies of forecasting the after spot electricity prices are offered.

Lämpöpumppujen vaikutukset sähköverkkoliiketoiminnan kannalta

Energiatehokkuus sekä ilmastonmuutos ovat aiheuttaneet pyrkimyksen vähentää kokonaisenergiankulutuksia erilaisissa rakennuksissa. Lämmitysjärjestelmissä tämä on näkynyt voimakkaana lämpöpumppumäärien kasvuna. Lämpöpumput vaikuttavat erilaisissa rakennus- ja lämmitystyypeissä myös sähköenergiankulutukseen. Lämpöpumppujen käytöstä saadaan eniten hyötyä lämmityskustannuksiin sähkölämmitteisissä rakennuksissa. Seurauksena on, että tällaisen rakennuksen sähkönkulutus ja siten myös sähkölasku pienenevät. Toisaalta muihin kuin sähkölämmitteisiin rakennuksiin asennettu lämpöpumppu kasvattaa sähköenergiankulutusta. Lämpöpumppuihin integroitu jäähdytysominaisuus myös tavallisesti lisää sähkönkulutusta. Tämän tutkimuksen tarkoituksena on selvittää, kuinka lämpöpumput vaikuttavat sähköenergiankulutukseen. Vaikutuksia tutkitaan sähköverkkoyhtiöiden kannalta sähköenergian ja liikevaihdon osalta. Tarkastelussa käytetään neljää yleisintä lämpöpumpputyyppiä, ja niiden toimintaa verrataan eri rakennustyyppien lämmitysjärjestelmiin. Työssä käsitellään lämpöpumppujen toimintaa ja käytettävyyttä muiden lämmitysmenetelmien korvaajina tai lisänä. Tämän kirjallisen työn lisäksi on tehty laskentaohjelma, joka on perusteena työssä esitetyille tuloksille. Sen tarkoituksena on selvittää lämpöpumppujen vaikutukset sähköverkkoliiketoimintaan energiayhtiöissä. Vaikutukset yksittäiseen energiayhtiöön ovat eniten riippuvaisia lämpöpumppujen asennuskohteista, lämpöpumppujen toiminnasta ja lämpöpumpputyypistä. Kuluttajat tulevat määräämään vaikutusten suuruuden, koska lämpöpumppujen lukumäärällä ja käytöllä on sähköenergiankulutukseen huomattava merkitys. Vaikutus sähköenergiaan energiayhtiöiden kannalta voi yleisesti ottaen olla 2020-luvulle mentäessä merkittävä. Tutkittavassa verkkoyhtiössä vaikutuksen sähköenergiaan arvioidaan olevan 10 % luokkaa yhdeltä vuodelta verrattuna tämän päivän kokonaissähköenergiankulutukseen. Vaikutus verkkoliikevaihtoon on arviolta puolet pienempi. Tällaiset tulokset edellyttävät lämpöpumppumäärän moninkertaistumista nykyisestä, mikä on myös odotettavissa.

Calculation of the carbon footprint of Finnish barley products - methodology and possible applications

The purpose of this thesis was to define how product carbon footprint analysis and its results can be used in company's internal development as well as in customer and interest group guidance, and how these factors are related to corporate social responsibility. From-cradle-to-gate carbon footprint was calculated for three products; Torino Whole grain barley, Torino Pearl barley, and Elovena Barley grit & oat bran, all of them made of Finnish barley. The carbon footprint of the Elovena product was used to determine carbon footprints for industrial kitchen cooked porridge portions. The basic calculation data was collected from several sources. Most of the data originated from Raisio Group's contractual farmers and Raisio Group's cultivation, processing and packaging specialists. Data from national and European literature and database sources was also used. The electricity consumption for porridge portions' carbon footprint calculations was determined with practical measurements. The carbon footprint calculations were conducted according to the ISO 14044 standard, and the PAS 2050 guide was also applied. A consequential functional unit was applied in porridge portions' carbon footprint calculations. Most of the emissions from barley products' life cycle originate from primary production. The nitrous oxide emissions from cultivated soil and the use and production of nitrogenous fertilisers contribute over 50% of products' carbon footprint. Torino Pearl barley has the highest carbon footprint due to the lowest processing output. The reductions in products' carbon footprint can be achieved with developments in cultivation and grain processing. The carbon footprint of porridge portion can be reduced by using domestically produced plant-based ingredients and by making the best possible use of the kettle. Carbon footprint calculation can be used to determine possible improvement points related to corporate environmental responsibility. Several improvement actions are related to economical and social responsibility through better raw material utilization and expense reductions.

Innovative Culture – Searching for Innovativeness in a Construction Company

The purpose of the thesis is to study innovativeness in a context of the construction industry especially the front-end of the innovation process. The construction industry is often considered an old-fashioned manufacturing industry. Innovations and innovativeness are rarely linked to the industry. The construction industry, as well as other industries in Finland, is facing challenges such as productivity, the climate change and internationalization. The meaning of innovations is greater than ever in continuously changing markets, for standing out from competitors or increasing the competitiveness. Traditional production methods, tight building regulations, unique buildings, one-of-a-kind project organizations and highlighting the cheapest price in building contracts are particular challenges in the construction industry. The research questions of the thesis were: - What kind of factors shift the existing company culture towards innovativeness? - What are the phases of the front-end of the innovation process? - What kind of tools and methods enable managing the front-end of the innovation process? The theoretical part of the thesis bases on the literature review. The research methodology of the empirical part was the action research and qualitative approach. Empirical data was collected by the theme interviews from three companies. The results were practical methods and experiences from innovation activities of the companies. The results of the thesis can be clarified as follows: enhancement of the innovation activities requires support and commitment of the top management, innovative culture and innovation strategy. Innovativeness can be promoted by systematical methods for example collecting ideas from employees. Controlling and managing the front-end phase is essential to succeeding. Despite that managing the front-end is the most challenging part of the innovation process, development and management of that save companies’ money, resources and prevents useless investments. Further clarification and studies are needed to find out furthermore functional tools and methods to manage innovations and implementing them to the culture of the companies.

Regime Switching Models for Electricity Time Series that Capture Fat Tailed Distributions

In the power market, electricity prices play an important role at the economic level. The behavior of a price trend usually known as a structural break may change over time in terms of its mean value, its volatility, or it may change for a period of time before reverting back to its original behavior or switching to another style of behavior, and the latter is typically termed a regime shift or regime switch. Our task in this thesis is to develop an electricity price time series model that captures fat tailed distributions which can explain this behavior and analyze it for better understanding. For NordPool data used, the obtained Markov Regime-Switching model operates on two regimes: regular and non-regular. Three criteria have been considered price difference criterion, capacity/flow difference criterion and spikes in Finland criterion. The suitability of GARCH modeling to simulate multi-regime modeling is also studied.

Technological and business challenges of smart grids

Growing recognition of the electricity grid modernization to enable new electricity generation and consumption schemes has found articulation in the vision of the Smart Grid platform. The essence of this vision is an autonomous network with two-way electricity power flows and extensive real-time information between the generation nodes, various electricity-dependent appliances and all points in-between. Three major components of the Smart Grids are distributed intelligence, communication technologies, and automated control systems. The aim of this thesis is to recognize the challenges that Smart Grids are facing, while extinguishing the main driving factors for their introduction. The scope of the thesis also covers possible place of electricity Aggregator Company in the current and future electricity markets. Basic functions of an aggregator and possible revenue sources along with demand response feasibility calculations are reviewed within this thesis.

A comparison of electricity spot prices simulation using ARMA-GARCH and mean-reverting models

The aim of this work is to compare two families of mathematical models for their respective capability to capture the statistical properties of real electricity spot market time series. The first model family is ARMA-GARCH models and the second model family is mean-reverting Ornstein-Uhlenbeck models. These two models have been applied to two price series of Nordic Nord Pool spot market for electricity namely to the System prices and to the DenmarkW prices. The parameters of both models were calibrated from the real time series. After carrying out simulation with optimal models from both families we conclude that neither ARMA-GARCH models, nor conventional mean-reverting Ornstein-Uhlenbeck models, even when calibrated optimally with real electricity spot market price or return series, capture the statistical characteristics of the real series. But in the case of less spiky behavior (System prices), the mean-reverting Ornstein-Uhlenbeck model could be seen to partially succeeded in this task.

Energiapalveludirektiivin 2006/32/EY toimeenpano ja vaikutukset

Euroopassa energiansäästöjen hakeminen on olennainen osa suurempaa ilmastostrate-giaa. Tämä työ tarkastelee direktiiviä 2006/32/EY energian loppukäytön tehokkuudes-ta ja energiapalveluista sekä sitä, millaisilla menetelmillä direktiivin esittämät toi-menpiteet otetaan osaksi kansallisia käytäntöjä Suomessa. Tämä diplomityö tarkastelee erityisesti elinkeinoelämän energiankäyttöä tehostavaa energiatehokkuussopimusjärjestelmää, koska se on keskeisin keino direktiivin toi-meenpanossa. Työ tarkastelee erityisesti energia-alaa painottaen sähkön tuotantoa sekä jakelua, koska sinne painottuvat myös direktiivin aiheuttamat lainsäädännön muu-tokset. Julkisen sektorin keskeistä roolia energiapalveludirektiivin toimeenpanossa käsitellään sekä esimerkillisenä energiankäyttäjänä, että suurena alihankintojen tilaajana. Myös energiapalveluyritysten liiketoimintaperiaatetta selvitetään tässä työssä.

Analysis of Patterns in Electricity Spot Market Time Series

Due to its non-storability, electricity must be produced at the same time that it is consumed, as a result prices are determined on an hourly basis and thus analysis becomes more challenging. Moreover, the seasonal fluctuations in demand and supply lead to a seasonal behavior of electricity spot prices. The purpose of this thesis is to seek and remove all causal effects from electricity spot prices and remain with pure prices for modeling purposes. To achieve this we use Qlucore Omics Explorer (QOE) for the visualization and the exploration of the data set and Time Series Decomposition method to estimate and extract the deterministic components from the series. To obtain the target series we use regression based on the background variables (water reservoir and temperature). The result obtained is three price series (for Sweden, Norway and System prices) with no apparent pattern.

Developing the Sourcing with the Purchasing Tool in the Chemical Company

The aim of this research was to investigate Tikkurila Oyj's Vantaa factories' current status in procurement and to develop the reporting of purchases and purchase warehouses, and to measure the activities during the implementation of the new purchasing tool. The implemented purchasing tool was based on ABC-analysis. Based on its reports the importance of performance measurements for the operations of the company, and the purpose of getting transparency to the company's supply chain on the part of purchasing were examined. A successful purchase- and material operation calls for accurate knowledge and professional skills. The research proved that with a separate purchasing tool, that analyses the existing information of the company's production management system, it is possible to get added value to whole supply chain's needs. The analyses and reports of the purchasing tool enable a more harmonized purchasing process at the operative level, and create a basis for internal targets and to their follow-up. At the same time the analyses clarify the current status and development trends of procurement fresh to the management. The increase of the possibilities of exploitation of information technology enables a perfect transparency to the case company's purchase department.

Sähköä ja lämpöä tuottavien voimalaitosten kannattavuusanalyysin kehittäminen

Tutkimuksen tavoitteena oli laskea voimalaitoskannattavuudet vuosilta 2007–2009 kohdeyrityksen biovoimalaitokselle sekä kombivoimalaitokselle. Lisäksi laskettiin kohdeyrityksen uuden hyötyvoimalaitoksen käyttöönottovuoden 2009 kannattavuus sekä odotetun käyttöasteen kannattavuus. Tavoitteena oli muodostaa tuotantolaitoskohtaiset tuotekannattavuudet vuodelta 2009 Kotkan Energia Oy:ssä sekä muodostaa kirjatut jakoperusteet kannattavuuksien laskentaa varten ja analysoida saatuja kannattavuuksia. Tutkimusmetodologiana on käytetty soveltavaa tutkimusotetta. Kannattavuusanalyysin kehittäminen vaatii yrityksen kustannusten, tuottojen ja toiminnan sekä toimialan luonteen ymmärtämistä. Haasteena tutkimuksessa oli sähkön, lämmön ja höyryn valmistuksen periaatteiden omaksuminen, joka on kustannusten ja tuottojen oikean kohdistamisen perusta. Tutkimuksen tuloksena todettiin, että kombivoimalaitos on tuotantolaitoksista kannattamattomin. Kohdeyrityksen kannattavuutta voitaisiin parantaa investoimalla kombivoimalaitoksen tilalle halvempaa polttoainetta käyttävä tuotantolaitos. Tuotteista kannattavimmaksi todettiin kaukolämpö. Tutkimuksen tuloksina saatuja kannattavuuksia voidaan hyödyntää Kotkan Energian päätöksenteossa ja niitä hyödyntämällä pystytään kohdeyritykselle laskemaan nopeasti tarpeellisia tulevaisuudenskenaarioita. Kannattavuuslaskelmien tuloksien analyysin jatkoksi pohdittiin Kotkan Energialle jatkotutkimusehdotelmia.
