More specifically, of the order of 50% of the effort bear on the EU electricity system in a context of an increasing share of variable renewable energy sources. Topics of the studies include detailed aspects such as consumers, demand-response, smart meters, smart grids, storage, etc., not only in terms of technologies but also in terms of regulations, market design and business models. Connections with other networks such as gas (e.g. security of supply) and heat (e.g. district heating, heating and cooling) as well as synergies between these networks are also be studied. The rest of the effort deal with heating and cooling, energy efficiency in houses, buildings and cities and associated smart energy systems, use of biomass for energy applications, etc. Foresight of the EU energy system at horizons 2030, 2050 are of interests. The ASSET project is carried on by a consortium led by Tractebel with Ecofys and E3M-Lab as partners. The studies will be achieved between 2017 and 2019.

More and more households will be equipped with smart meters which will enable them to monitor and adapt their consumption of electricity more accurately and timely. Moreover, the integration of intermittent renewables in the electricity mix requires increasing demand side management. Dynamic prices can thereby lead to energy system cost reductions, energy savings, and increased market awareness and transparency. However, before any adoption of dynamic pricing the structure of electricity pricing needs to be studied in detail and the options of dynamic price models need to be better understood. In this study, we propose strategies for the further implementation of dynamic retail electricity prices in the EU. For this purpose, we describe firstly the current electricity price structure in chapter 2. The options, impacts and potential of dynamic electricity prices are discussed in the chapters 3, 4 and 5 respectively. In chapter 6 we provide an overview of the current dynamization development across the EU before we draw our conclusions and make our recommendations for dynamic retail electricity price strategies. 1 EC, 2018 PAGE | 5/53 asset February, 2018 7 2 ELECTRICITY PRICE STRUCTURE In this chapter, the structure of electricity prices is described for all Member States for various consumer classes. Firstly, we describe the split of the retail electricity prices into components that relate to the described activities in the process of electricity supply as it has been applied in previous studies2. In addition, we define representative consumers to allow for a comparison of electricity prices between Member States. Finally, the structure and the components that constitute the final electricity retail price are presented, providing the basis for the potential assessment of increased price dynamization in the remainder of this report. 2.1 Methodology and assumptions The electricity supply involves different activities; the generation of electricity in conventional or renewable power plants, its transmission and distribution towards final consumers using electricity networks, and trading at wholesale and retail markets. Those activities are typically financed by allocating the respective costs to final consumers as part of the electricity price. Retail prices refer to the prices paid by the final consumer, for example households or industry. Retail electricity prices are typically divided into three components: energy, network and taxes & levies. The energy component reflects the generation stage, the network component relates to the transmission and distribution stages and taxes & levies finance policy support costs and other regulated activities. Figure 1 illustrates the theoretical impact of government policies on the different components of electricity prices.

  • Czech Republic
    June 2020 Czech Republic The OECD Inventory of Support Measures for Fossil Fuels identifies, documents and estimates direct budgetary support and tax expenditures supporting the production or consumption of fossil fuels in OECD countries, eight partner economies (Argentina, Brazil, the People’s Republic of China, Colombia, India, Indonesia, the Russian Federation, and South Africa) and EU Eastern Partnership (EaP) countries (Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine). Energy resources and market structure Total Primary Energy Supply* in 2018 The Czech Republic is the fourth-largest net electricity exporter in the EU in 2018, after France, Germany, and Sweden. Most of its Coal, 35% Geothermal, exports flow into Austria, the Slovak Republic solar & wind, and Germany. In 2018, electricity was mainly 1% generated from coal (50%) and nuclear energy Oil, 21% (34%). Small amounts of natural gas (4%) were used as a complement in multi-fired units and Biofuels & in peaking units. Roughly one-third of the waste, 10% Natural gas, 15% country’s electricity produced from coal is Nuclear, generated in combined-heat-and-power 18% plants. *excluding net electricity import Source: IEA In the Czech Republic, fossil fuels have always played a big role in the energy mix and still account for the bulk of total energy supply and domestic energy production. This is due to the substantial coal resources available in the country. Ostravsko-Karvinské Doly (OKD), the country’s sole hard-coal producer and one of the largest employers, operates four deep bituminous coal mines in the Moravian-Silesian Region. There have been ongoing re-organisation in the country’s mining industry in light of recent insolvency procedures in OKD, with the government announcing a gradual phasing out of mining by 2030 at the latest.

  • Real-Time Pricing in the Swedish Electricity Market Bachelor Thesis, Department of Economics
    Real-Time Pricing in the Swedish Electricity Market Bachelor Thesis, Department of Economics Hjalmar Pihl Advisor: Associate Professor Tommy Andersson, PhD 17 January 2012 ABSTRACT An introduction of real-time prices of electricity, i.e. prices that correspond to the hourly spot market price, for residential consumers in Sweden has recently been suggested. Support for real-time pricing comes from governmental agencies as well as commercial interests, however without a good understanding of how a shift to real-time prices would affect prices and volumes in the market, and what welfare effects these changes would induce. This thesis addresses these issues by developing a model of the Swedish electricity market. The conclusion is that an introduction of real-time pricing would have a smoothing effect on prices and volumes, which in turn is likely to have positive welfare effects on producers and on the consumers that shift, but a negative effect on the larger consumers that already pay by the hour. The net welfare effect is likely to be positive. Keywords: Electricity, Real-Time Pricing, Sweden 1 TABLE OF CONTENTS 1.

The reasons are twofold: capitalizing on carbon emissions whilst concomitantly benefiting from reduced fossil fuel dependence and the fluctuations associated with imported fuel prices. However, numerous countries have not yet made preparations to increase RE production and integration. In many instances, this reluctance seems to be predominant in energy-rich countries, which typically provide heavy subsidies on electricity prices. With such subsidies, there is no incentive to invest in RE since the time taken to recoup such investments would be significant. We develop a model using a Neural Network (NN) regression algorithm to quantitatively illustrate this conjecture and also use it to predict the reduction in electricity price subsidies required to achieve a specified RE production target.

    PEAK DEMAND AND TIME-OF-USE PRICING IN A FIELD STUDY OF RESIDENTIAL ELECTRICITY DEMAND IN GERMANY Joachim Schleich: Grenoble Ecole de Management, Grenoble, 12, rue Pierre Sémard, BP 127, 38003 Grenoble, France [email protected]. Marian Klobasa: Fraunhofer Institute for Systems and Innovation Research ISI, Karlsruhe, Germany Phone: +49 (0) 721 6809 287, Fax: + 49 (0) 721 6809 272, e-mail: [email protected] Overview According to the EU Energy Services Directive 2006/32/EC 2010 utilities need to offer final customers of electricity a tariff which provides incentives to save electricity. Such tariffs may vary by load or by time of use (TOU). Unlike flat rates, dynamic pricing (including time of use pricing), more adequately reflects the true marginal cost of electricity supply, sets financial incentives to shift demand from peak loads to off-peak loads, helps integrate fluctuating renewables (notably wind and solar) and plug-in electric vehicles into the electric grid, and - depending on its magnitude and geographical location, the shift in demand and improved load management may also save costs for building and running generation and transmission infrastructure (e.g. Borenstein 2005, Faruqui and Palmer 2011, Joskow 2012). While various types of dynamic pricing schemes have been implemented in the US more than three decades ago (e.g. Faruqui and Malko 1983, Darby 2006, Ehrhart-Martinez et al. 2010, Faruqui and Sergici 2011), in most EU countries, these schemes have just started to diffuse, typically in response to the EU regulation, and primarily via pilot projects (e.g. Torriti et al.

  • Residential Real-Time Pricing: the Energy Smart Pricing Plan
    Residential Real-Time Pricing: The Energy Smart Pricing Plan Kathy Tholin, Larry Kotewa, and Anthony Star, Community Energy Cooperative Michael Ozog and Mark Thornsjo, Summit Blue Consulting Lisa Skumatz, Skumatz Economic Research Associates, Inc. ABSTRACT The Energy-Smart Pricing Plan (ESPP) was started in January 2003, and was the first time in the nation that residential customers were given the opportunity to pay market-based electricity prices. By exposing residential customers to the market-price of electricity, customer’s are given the opportunity to make informed decisions about electricity use. This program uses Commonwealth Edison’s (ComEd’s) experimental Residential Hourly Energy Pricing (RHEP) rate. In addition to the hourly electricity price, participants receive a distribution charge which is currently capped at 4.88 and 5.367 cents per kWh for single family and multifamily homes, respectively. Program participants’ rates are reduced by 1.4 cents/kWh as a participation incentive. Through this feature, participants could save about 10% of their current electric costs even if they do not change their energy use patterns at all in response to the hourly energy prices. This paper presents the quantitative and process assessments of the ESPP using statistical modeling of hourly consumption data and survey responses. Through this evaluation, we have found that residential customers do indeed respond to hourly price signals, even relatively small ones. Introduction This paper presents the results from both a quantitative and process assessment of the Community Energy Cooperative’s (Cooperative) Energy-Smart Pricing PlanSM (ESPP) residential real-time pricing (RTP) program for the year 2003. The ESPP program is the first large-scale residential RTP program in the United States.
