The energy "Trilemma" seeks to develop an electricity market which simultaneously ensures environmental quality, security of supply, and economic sustainability. The objective of this paper is to present the "Trilemma" energy as the latest trend in the design of energy policy. For this, a theoretical framework is presented in sections 2 and 3, in section 4 and 5 the importance of security of supply and economic sustainability are discussed, respectively. In section 6 the energy "trilemma" is presented, in section 7 a brief state of the art is showed. Finally in section 8, it is approached three different electricity markets. It is concluded that the regulator has passed in recent years from encouraging a liberalized market scheme, to promote a scheme based on intervention through policies that affect the market competitiveness but allow achieving its environmental goals.

Collateral mechanism in the Electricity Market ensures the payments are executed on a timely manner; thus maintains the continuous cash flow. In order to value collaterals, Takasbank, the authorized central settlement bank, creates segments of the market participants by considering their short-term and long-term debt/credit information arising from all market activities. In this study, the data regarding participants’ daily and monthly debt payment and penalty behaviors is analyzed with the aim of discovering high-risk participants that fail to clear their debts on-time frequently. Different clustering techniques along with different distance metrics are considered to obtain the best clustering. Moreover, data preprocessing techniques along with Recency, Frequency, Monetary Value (RFM) scoring have been used to determine the best representation of the data. The results show that Agglomerative Clustering with cosine distance achieves the best separated clustering when the non-normalized dataset is used; this is also acknowledged by a domain expert.

Abstract Electric power sectors around the world have changed dramatically in the last 25 years as a result of sector liberalization policies. Many electricity sectors are now pursuing deep decarbonization goals which will entail replacing dispatchable fossil generation primarily with intermittent renewable generation (wind and solar) over the next 20–30 years. This transition creates new challenges for both short-term wholesale market design and investment incentives consistent with achieving both decarbonization commitments and security of supply criteria. Thinking broadly about the options for institutional change from a Williamsonian perspective – thinking like Williamson – provides a useful framework for examining institutional adaptation. Hybrid markets that combine ‘competition for the market’ that relies on competitive procurement for long-term purchased power agreements with wind, solar, and storage developers, ideally in a technology neutral fashion, and ‘competition in the market’ that relies on short-term markets designed to produce efficient and reliable operations of intermittent generation and storage, is identified as a promising direction for institutional adaptation. Many auction, contract, and market integration issues remain to be resolved.

Renewable energy is a widely used term that describes certain types of energy production. In politics, business and academia, renewable energy is often framed as the key solution to the global climate challenge. We, however, argue that the concept of renewable energy is problematic and should be abandoned in favor of more unambiguous conceptualization.Building on the theoretical literature on framing and based on document analysis, case examples and statistical data, we discuss how renewable energy is framed and has come to be a central energy policy concept and analyze how its use has affected the way energy policy is debated and conducted. We demonstrate the key problems the concept of renewable energy has in terms of sustainability, incoherence, policy impacts, bait-and-switch tactics and generally misleading nature. After analyzing these issues, we discuss alternative conceptualizations and present our model of categorizing energy production according to carbon content and combustion.The paper does not intend to criticize or promote any specific form of energy production, but instead discusses the role of institutional conceptualization in energy policy.

Sub-Saharan Africa has the lowest energy consumption per capita in the world, and this has undermined socioeconomic development in the region. The stationarity of energy consumption in the region has important implications for energy policy, forecasting and macroeconomic developments. This paper investigates the stationarity properties of energy consumption in 48 sub-Saharan Africa countries using the Augment Dickey–Fuller, Zivot–Andrews, Clemente–Montanes–Reyes and Lee–Strazicich LM tests. Using the Lee-Strazicich LM test as a benchmark, the study shows that energy consumption is stationary in 41 countries. This implies that energy policy makers should not be concerned about shocks in energy consumption in these countries because the shocks will be temporary and not transmitted to the macroeconomy. Also, energy policies will not have long-term effects. Policies that exert one-time temporary shocks on energy consumption would be more effective in these countries.
