Climate change related emissions have emerged as one of the adverse effects of unsustainable energy use, which poses the challenge of ensuring energy sustainability while accounting for climate change mitigation. In this paper, using the Energy Indicators for Sustainable Development framework, an assessment of GHG emissions trends along with national and international pledges for a set of developed (Portugal and United Kingdom) and developing countries (China and Brazil) is presented, contributing for an insightful comparison of countries that share a common cause, irrespective of their developmental stage. The preliminary results show that UK and China need to focus on the improvement of the renewable nature of their energy mix, whereas Portugal and Brazil need to focus more on measures that contribute to improve the efficient use of energy. Hence, environmental and energy intensity indicators together have allowed to emphasize aspects that would otherwise separately pass unnoticed.

Brazil is one of the countries in the world with highest potential for solar energy supply. In the last years, Brazilian electricity regulation has undergone through considerable changes, most of them to stimulate and promote micro and mini decentralized energy supply arrangements, smart grid solutions and other technologies related to it. Despite of it, there is lack of studies addressing problems like market and user's potential and how markets and services should be prepared to absorb decentralize solar energy generation, especially considering medium and low voltage consumers. Therefore, the articles purpose is to study, using a real option approach, the viability of decentralized solar energy generation's investments considering different market designs. As in Brazil, decentralized energy supply is still incipient; a real option approach provides different scenarios and insights for stakeholders to understand possible market designs conceptions.

The German electricity market is undergoing the largest transformation since its liberalization. With increasing shares of renewable generation and decreasing spot exchange prices utilities are searching for new business models. Lessons can be learned from the telecommunication industry which has been liberalized at similar times but has been more competitive and customer centric since. In this paper we review the development of both industries along the four dimensions of competition, tariff design, auction design and the quality of service. We then develop an electricity market design based on experiences from the development of the telecommunication industry.

The described work analyses the issue related to the application of a nodal pricing methodology to the Italian power system. If on one side the nodal pricing methodology has proven to be the best possible solution for electric energy, on the other side the application to the Italian power system introduces some problems. This paper presents the peculiarity of application to the Italian real time balancing market with a scenario developed on a case study in order to show up the possible system distortions.

There are novel technical solutions and complex market roles in the energy market that cannot be associated with one single market participant and thus are difficult to be fitted into the current energy market environment. The article analyzes these assets and roles to help regulators encourage the spread of energy storage assets, enable demand-side flexibility and its appearance on the flexibility market through aggregators.

As the transition to more renewable energy sources progresses the regional generation clusters of wind and solar generation increase. Since the transmission capacity is limited we can observe an increasing need for redispatch measures in the German electricity grid to accommodate this development. In this paper we analyze the need and costs of redispatch measures and propose a local electricity market setup to create economic incentives for the expansion of generation capacity close to load centers. We introduce an analytical model to investigate small networks and a graph model simulation to deal with more sophisticated structures. We find that redispatch is especially relevant in networks with bottleneck transmission links and rather independent of the overall grid capacity. Furthermore, we argue that transmission capacity needs to be priced explicitly and that graph theory can help in investigating market mechanisms in electricity grids.

Renewable energy sources are currently presented as an economically viable and environmentally safe option in the near future. A major constraint to the incorporation of wind and solar generation at large scale is the increase of variability in the power system. To assure the perpetual balance between power production and gross consumption a significant improvement on power systems flexibility is required. Such flexibility in the power system can be achieved by two options on the demand side through demand response obtained through industrial processes: Storage and Substitution. The power system model in study contemplates the purchase of electricity from the Dutch Balancing Market. The electricity prices of the Balancing Market are considered unpredictable. The storage system is characterized by the size of the storage tank and by ramp up/down rates, reflecting the changing speed of the production levels. The substitution system is characterized by the ramp rate of substitution between electricity and an alternative energy carrier as input. The impact of the parameters on the Power System Flexibility when connected to the balancing market under several scenarios was analyzed by Linny-R, a software tool that applies Linear Programming optimization. For the storage system a bigger tank size, a higher ramp rate and a high level of predictability will increase the flexibility of the system. As the actual predictability of the balancing market is limited, the flexibility is limited too, which makes the storage system a questionable option. For the substitution system flexibility is increased by a higher ramp. The effect of the predictability is less dominant, which makes substitution a suitable flexibility enabler for the current Dutch market system. In this context, a restructure of the energy markets, considering the prices predictability, is suggested, as a way of easing the penetration of renewable energy sources.

Market power and its possible abuse by market participants is one of the main issues in electricity trading and a lot of work is done on establishing trading rules for fair and transparent electricity market. The focus of this paper is to present market power detection techniques which have been proposed in literature with detail review of the tools which could be used in monitoring units of organised electricity market places such as power exchanges. Electricity markets are disposed to collective or collusive market power exercise because of their characteristics and additionally susceptible to the potential exercise of unilateral market power. There have been many insight researches on topic of market power in the deregulated wholesale electricity markets with arising questions how to define, exercise and detect market power. The paper distinguishes between different models for market monitoring and surveillance and the outcomes of the paper can serve as a recommendation and orientation for further tests and researches in the field of the monitoring of market power.

Russia is the second largest gas producer in the world after the US and the main exporter of natural gas to the EU. There were 257 gas-producing companies in Russia at the beginning of 2016, among them the largest producer and exporter of the pipeline gas — Gazprom with production share of 64 %. Currently, Gazprom maintains the status of the pipeline export monopolist. At the same time, it receives the regulated tariffs in the domestic market, as a measure to restrict the market power in the domestic market. The objective of the paper is to examine the impacts of natural gas policy change on the domestic electricity market of Russia. The paper considers different scenarios of the Russian gas market deregulation, and their impact on the electricity prices. A mixed complementarity approach is used to estimate gas prices and its volumes depending on specific policy decision, and final electricity price in different price zones. Russian domestic gas market policy is an important topic, which is often interrelated with export policy, however, receives less attention, and a current paper aims to fulfill this gap.

This paper proposes a methodology for modeling mothballing decisions in order to better study the different strategies adopted by power plants owners and their impact on power systems (in particular generation adequacy). A system dynamic approach is adopted to build a model which represents investment, mothballing and shutdown decisions in an energy-only market. The results obtained with the proposed modelling methodology highlight the importance of considering mothballing in long term simulation models of power markets. They show how models which neglect mothballing decisions might overestimate or underestimated the level of available capacity, therefore leading to inappropriate policy choices. The proposed methodology could better inform policymakers on their decisions.
