Formation of common European energy market implies the necessity of making adjustments to domestic low and adopt market development possibilities in order to meet European Union regulations. Implementation of system support to develop high-efficiency cogeneration was one of those aspects. Several years of functioning such mechanism allow to: analyze those regulations and their impact on sub-sector development, make a deep cost analysis and discuss about its efficiency. This paper describes the background of implementation of EU regulations, results of efficiency analysis and comparison with the functioning mechanism in the Flemish Region.

The aim of this paper is to describe and measure risk on the Polish & German Energy Market. The risk was estimated with three types of Value-at-Risk measures: VaR, stress VaR and Incremental Risk Charge (IRC). These measures were calculated on time series of logarithmic daily rates of return of indexes from the Polish Power Exchange (POLPX) andthe European Energy Exchange (EEX) spot market. Based on time series from 01.2009 to 28.09.2012 we attempted to answer the two questions: which measure is more appropriate for risk estimation, and where the risk level is higher.

Liberalization on the electricity market in Poland is related to the possibility of free choice of electricity supplier. On a liberalized market, suppliers have to compete to gain new customers and retain the old ones. The suppliers have to satisfy the customers’ needs − which are more and more complex − and customize their approach. Therefore, negotiations of electricity sale conditions become an usual practice. The purpose of this study is to propose a way of supporting the negotiation process of electricity sale conditions between a supplier and a customer. To solve this problem, the scoring method has been used.

The aim of this paper is the analysis of risk on Scandinavian energy market: Nord Pool Spot. The analysis is based on Value-at-Risk and Expected Shortfall. As the normality assumption for linear returns of prices has been rejected, the alternative distribution has been proposed: the alpha-stable distribution. The results shown that there are some differences between risks among submarkets of Nord Pool Spot. Moreover, the alpha- stable distribution better approximate real Value-at-Risk than normal one only if quantiles of order 0,05 and 0,95 are considered.

Progressing liberalization and electricity market development in Poland results increase of competitiveness. The new products being offered to customers are increasingly more complex and sophisticated. Accordingly, it requires a challenge for both portfolio and risk management skills. Considering market risk peculiarity within the frame of energy market as well as lack of energy derivatives market - including options contracts, position's hedging becomes very difficult. Hedging efficiency determines risk exposure and furthermore risk capital demand. Dynamic hedging approach described in this paper has been focused especially on short position in call option, written as a compliment - additional value for customer. The main purpose of presented approach is to provide stable enough financial performance and adequate risk's yield premium.

Wdrażanie infrastruktury Smart Grid (tzw. inteligentnej sieci elektroenergetycznej) spowodowało pojawienie się nieznanych wcześniej problemów związanych z przetwarzaniem oraz analizowaniem dużych i zróżnicowanych zbiorów danych, które z uwagi na bezpieczeństwo sieci i uczestników gry rynkowej powinno być realizowane w czasie niemal rzeczywistym. Co więcej, postępujące na rynku energii elektrycznej zmiany implikują przejście od modelu tradycyjnego do rynku bardziej zorientowanego na klienta. Wynika to przede wszystkim ze zwiększonego dostępu do narzędzi i informacji pozwalających na monitorowanie i redukcję zużycia energii oraz rosnącej świadomości konsumentów odnośnie do przysługującego im prawa zmiany sprzedawcy energii elektrycznej. Portale internetowe czy media społecznościowe stają się miejscem dyskusji, porównania i oceny obecnie dostępnych ofert. Tym samym odpowiednio przeanalizowane informacje publikowane za ich pośrednictwem mogą być źródłem budowania przewagi konkurencyjnej firmy. Artykuł ocenia możliwości wsparcia potrzeb informacyjnych przedsiębiorstw funkcjonujących na rynku energii elektrycznej poprzez wykorzystanie analizy wydźwięku opinii klientów o operatorach energetycznych oraz o produktach przez nich oferowanych.

The implementation of the Smart Grid infrastructure caused previously unknown problems connected with processing and analyzing large and diverse data sets. Due to the security of the electricity network and the market participants, the processing and analyzing large data sets should be achieved in the near real-time. Furthermore, the changes in the electricity market have implied a shift from the traditional market model to the customer-oriented market. This is primarily a result of the increasing access to the tools and information which allow consumers to monitor and reduce the energy consumption, and of the customers' growing awareness about the right to change their electricity supplier. Web portals and social media have become a place for discussion, comparison and review of the currently available offers. Thus, the proper analysis of the information published on such websites can be a source of competitive advantage for the electricity suppliers. The article shows a possibility to support the information needs of electricity companies by means of the sentiment analysis of customer's reviews on energy suppliers and on the services they offer.

Celem pracy jest przeprowadzenie analizy porównawczej ryzyka zmiany ceny oraz wolumenu obrotu na rynku energii elektrycznej oraz rynku gazu prowadzonych przez Towarową Giełdę Energii. W pracy została przeprowadzona analiza rozkładów stóp zwrotu z omawianych rynków, na podstawie której zaproponowano miary estymacji ryzyka. Na bazie oszacowanego ryzyka zostanie przeprowadzona analiza porównawcza poziomu ryzyka na poszczególnych rynkach.
