The break-even principle has been a fundamental principle for the price regulation of the Danish utilities for several decades. Following the liberalization of parts of the energy sector, this regulation has been supplemented with new instruments to regulate monopoly areas. This form of regulation was introduced in connection with a new electricity supply regulation from 1999. The detailed design of the income-cap regulation has been left to the Minister responsible for the energy sector and the supervisory authority (currently the Danish Utility Regulator). Income-cap regulation of power grids has given rise to several challenges. Thus, the specific design of the revenue framework has been changed several times. At the same time, however, some experience has been gained with the administrative handling of this form of regulation. Several cases have, in the absence of administrative courts in Denmark, been dealt with by the Danish Energy Board of Appeals. Since the introduction of revenue frameworks, the power (electricity) sector has changed. Furthermore, the sector must adapt to the Green Transition, which will require capacity expansion at both transmission and distribution levels, or other measures must be taken to prevent bottlenecks in the system. In this paper the income-cap experience will be discussed.

Funding provisions by policy makers are usually for two main purposes including poverty and inequality reduction as well as improvement of the situation for private sector growth. Nigeria returned to civilian rule in 1999 and has since been pursuing private sector-led growth and development and one of the sectors constituting the focus of the federal government is the energy sector especially the electricity sub-sector. This study analysed federal government spending on the energy sector with special emphasis on the electricity sub-sector to see how this spending has impacted on production, transmission and distribution of electricity using descriptive statistics. The study found that despite the significant reforms and increase in spending in the sector, the outcome in terms of its reflection on production, transmission and distribution of electricity is far from the realisation of the reform objectives. The country lags behind other countries like Libya, Kenya and Ghana in per capita power production and consumption and this lack of access to electric power, and modern energy in general has a negative effect on productivity and has limited the economic opportunities available to Nigeria. The study recommended going back to the NEEDS policy thrust and targets in the power sector and must pay attention to the environmental consequences of various options for enhancing the provision of energy services.

This paper analyzes the development and problems of electricity sector in Indonesia. After the economic crisis of 1997/98, investment in power sector has been decreasing. Minimizing transmission and distribution loss can increase reliability and quality of power supply, improve financial capacity, and reduce electricity subsidy. Electrification ratio and electric power consumption per capita need to be improved equally among provinces. Promoting public private partnership (PPP) can boost investment. Main policy challenges need to be addressed are that government needs to (1) provide information on the investment prospects; (2) solve social aspect of the project; and (3) provide practical guide in land acquisition.

Reliability of power supply of consumers is an important task in the process of transmission and distribution of electric energy. The paper proposes a method for assessing the consequences of power failures of monoconsumers of electric energy on the example of an oil company and an adjacent power grid company. The uniqueness of the developed technique lies in the possibility of reliable calculation of reliability of power supply of complex branched electric networks without taking into account the specific scheme of power supply. The accuracy of calculations is increased due to the use of data directly studied power system, taking into account the specifics and operating conditions of specific equipment, instead of the average information. Classification of failures on the main reasons in electric networks of the oilproducing enterprise of the far North that allowed to develop actions for increase of level of reliability of power supply is made.

This paper analyzes temporal and spatial process, and problems based on data between 1986 and 2010. Conclusions are as follows. Power supply of Guangdong relied more on distant outer-province power grids over time, not inner-province ones, close ones or independent power plants. This accelerating enlargement of power supply range could well satisfy its increasing power consumption. However, power production of western provinces couldnt simultaneously meet their own increasing demand and demand by Guangdong. Furthermore, total power transmission and electricity tariff were fixed by long-term framework agreements signed among governments, in which the transmission amount was too much while the tariff was too low, forcing the western provinces limiting their domestic demand without proper compensation. So the current enlarging trend of power supply range of Guangdong is unsustainable and its necessary to introduce power market mechanism through adjusting short-term total power transmission and power tariff according to the market situation.

Power supply security tops the agenda of policies, and it is related to restructuring with the intention of improving efficiency. To investigate relationships between restructuring and reliability in the electricity industry of 15 OECD countries from 1987 to 2013, reliability is measured by the index of the sub-sectors (resources, generation, transmission and distribution, and electricity import), and the effects of the forms of liberalized restructuring—entry, privatization, and vertical divestiture—on sub-sectors are evaluated with the random-effect model. Results indicate that restructuring has a partially negative relationship with reliability, but the effect differs by the type of liberalization and supply sub-sectors.

The relevance of the work is determined by the need to improve the electrical distribution grids of railways on the basis of digital technologies. The article presents advanced methods of transportation and distribution of electric power in smart power grids of railways based on multi-agent control. The analysis of the power supply system for stationary railroad consumers was performed and advanced ways of their development were defined. These methods should provide increased speed, adaptive determination of restrictions on using electric power equipment, management of mode parameters, sectioning and power flow modes in electrical distribution grids, restoration of power supply after emergency events. The method of adaptive control of transportation and distribution of electric energy in the power supply system of stationary railway consumers is developed based on the hierarchical structure of IEC 61850. This method takes into account the coordination of managing and local controllers in the data exchange environment, the control results and the variable area of responsibility of controllers and their division according to their functional purpose based on the multi-agent approach. The method of power flow control was developed to reduce power losses, increase the capacity of transport channels and ensure the restoration of the normal mode of the electric network by reconfiguring it and controlling active elements based on graph theory. The method takes into account the expected daily load curve, limits on the demand for capacity by active consumers and the possibility of a closed mode of electrical network operation through controlled cross-sections. The simulation results presented on the test circuit have showed the feasibility and efficiency of the proposed approaches.

Digitalization is a transformation process which has already affected many parts of industry and society and is expected to yet increase its transformative speed and impact. In the energy sector, many digital applications have already been implemented. However, a more drastic change is expected during the next decades. Good understanding of which digital applications are possible and what are the associated benefits as well as risks from the different perspectives of the impacted stakeholders is of high importance. On the one hand, it is the basis for a broad societal and political discussion about general targets and guidelines of digitalization. On the other hand, it is an important piece of information for companies in order to develop and sustainably implement digital applications. This article provides a structured overview of potential digital applications in the German energy (electricity) sector, including the associated benefits and the impacted stakeholders on the basis of a literature review. Furthermore, as an outlook, a methodology to holistically analyze digital applications is suggested. The intended purpose of the suggested methodology is to provide a complexity-reduced fact base as input for societal and political discussions and for the development of new digital products, services, or business models. While the methodology is outlined in this article, in a follow-up article the application of the methodology will be presented and the use of the approach reflected.
