The importance of corporate social responsibility (CSR) has aroused wide attention of not only the corporation itself, but also the whole society. In 2006, SGCC (State Grid Corporation of China) published its first CSR report, started to make a commitment to social responsibilities. Since then, the five power generation groups published their CSR reports, sustainable development reports, or development...
Needs for adequate long-term planning in the execution of energy generation to meet growing demand leads to intense regulation on energy distributors. A research was realized by a Brazilian distribution company to identify the consumption prediction methods, the nature of the decision process and their specific interaction scheme. Were initially identified the models already used by other distribution...
Over the next 4–5 years all Norwegian electricity customers will follow the rest of Europe in implementing automatic meter reading. For the customers, this means new opportunities to monitor one's own power consumption, simpler invoices, access to new services, and it is no longer necessary to read and report the measurements to the grid operator. For the power industry this is an extensive project,...
The technology of energy management called "Sistema de Gestión Integral de la Energía, SGIE” was proposed in Colombia in 2007 as a result of a research project funded by the Colombian government. The SGIE technology consists of statistical and monitoring tools, energy efficiency indicators and conforms to the requirements of the Standard ISO 50001. This technology allows the measurement of energy...
Photovoltaics (PV) offer a unique opportunity to solve the 21st century's electricity generation problem because solar energy is essentially unlimited and PV systems provide electricity without any undesirable impact on the environment. With current technology of silicon based PV systems, volume manufacturing, appropriate business model and without any subsidy, PV electricity can be generated today...
Green energy is an important part of solution for future energy concern. Electricity is a magnificent form of energy with potential of increasing efficiency in different processes. The department of energy report that came out last year, points out that −12% is the saving of carbon dioxide emissions from the UK electricity sector by increasing penetration of consuming green energies. It is an obvious...
This presentation will discuss the various outreach initiatives that both National Grid and PES are using to reach out to pre-college children and teenagers to make them aware of the opportunities in the power industry. The goal is introduce them to electricity as well as to some of the more interesting aspects of our industry.
Power crisis is one of the burning hindrances which are slowing down the socio-economic improvement in the developing countries. Without power all development activities come to rest. Demand for power is everywhere which had increased 50 times in the last 10 years. Bangladesh is a country of immense potential but she is associated with many major problems. Among them power shortage has emerged as...
Russian electric power industry has been moving towards deregulation of electricity generation and sale since 2003. Eight years of the Russian electric power industry restructuring and some years of electricity market functioning provide some statistical information. Price trends are among the most important to estimate what restructuring decisions are a success and what regulation needs further development.
Incentive regulation is moving towards new schemes where standard efficiency mechanisms are combined with output-based incentives (related to quality of supply, sustainability and innovation). Assessing performance of regulated utilities requires models capable to account for these different regulatory objectives. Benchmarking analysis has been in use for a long time; however, whether these models...
This paper describes the models that were used and the results obtained to estimate the Congestion Cost of the Portuguese National Transmission Network. This network is established at 400 / 220 and 150 kV and the Tariff Code in force is Portugal determines the use of a postage stamp based approach discriminated by voltage level to set the tariffs for the use of the transmission system. However, the...
Electricity as a vital tool in national development is receiving increasing attention from various regimes of Government in Nigeria. Obviously, there is a great deal of potentials for investors in the country, this is the idea behind the reforms in the industry. The recent roadmap to the reform of electricity industry in the country is a veritable pointer to this argument. Meanwhile, therein lay a...
Provision of adequate supplies of electricity is one of the most challenging policy issues in the recently restructured Russian electricity market. In 2008 a decision was taken to develop a capacity market in order to ensure reliability of supply and timely investments. At the time, Russia experienced a considerable capacity deficit and thus waiting for market-based investments was not a viable option...
With the advent of power system restructuring, there is now competition on the generation activity and the generation mix changed in many countries with the incentives to induce investments in renewables, in many cases, using volatile primary resources. Given this increase of the installed capacity in wind parks and PV stations as well as in hydro stations (as a way to address the mentioned volatility),...
European Union (EU) regulations and economic trends are shaping the future of customer-focused energy policies. Regulations encourage utilities to introduce new energy technologies and increase energy efficiency for their customers. At the same time, consumers are becoming more conscious of various opportunities in energy markets, and new technologies are driving new products and services to the energy...
As it is well known, competitive electricity markets require new computing tools for power companies that operate in retail markets in order to enhance the management of its energy resources. During the last years there has been an increase of the renewable penetration into the micro-generation which begins to co-exist with the other existing power generation, giving rise to a new type of consumers...
The city of St. Gallen needs an estimate for electricity demand in 2050. 20 existing scenarios of 9 different issuers had been adapted to the city of St. Gallen. All the scenarios used give a range of 1'369 GWh to 360 GWh. Based on a comparison, we assess the results and select the relevant scenarios. The remaining seven scenarios show a range of 745 GWh to 360 GWh in 2050. Based on interviews with...
Smart grids are described as a tool to pursue a diverse set of political and environmental energy goals. Visions of smart grid implementation differ around the world, and roles in smart grids are not yet clearly defined and assigned. This paper systematically explores smart grid visions and pilot projects in selected countries representing different electricity system types: centralized versus decentralized...
The demand for electrical power is not constant. There are certain times of the day where the demand levels are much higher than the rest of the day. The demand can often exceed the generation capacity and when that happens, the utility companies can either shed loads or buy additional electrical energy from wholesale electricity markets to close the gap between demand and supply. These markets clear...
This paper used panel regression and GARCH analysis to investigate changes in volatility of total returns of European energy companies due to energy sector liberalisation events. The paper constructed an index of 24 energy companies and calculated a 22 days rolling standard deviation of daily total returns over a 21 year period. Eight liberalisation events were identified. An unbalanced random-effects...
