Cyclones swirl the air masses washing out city colors of autumn. Fallen leaves cover park lanes and pathways. Lights come up earlier thus autumn is actually here. Ukrenergo Review play the fiddle in this symphony as well. Listen and enjoy:
- Bad weather but good consequences. On Saturday, a record 24.6% of total electricity came from wind power sources in the 28 countries of the European Union. Yes, it is an absolute record The amounts of electricity generated were enough to power 197 million European households or 68% of all industrial electricity needs. 88,7% of the energy were generated from the onshore wind farms while 11,3% – from the offshore ones. All across Europe individual countries were being powered by significant amounts of wind. Denmark – who casually breaks 100% on a regular basis these days – topped out the chart on at 109%. Germany’s 61% is amazing for such a large country of more than 82 million people. At least 10 of 28 countries of the EU got greater than 20% of their electricity from the wind on Saturday. It should be mentioned as well that these record wind numbers were seemingly the front end of deadly storms that strew damage across the central portion of the Storms however serve as the customary rule in the open oceans proving the recent researchsuggestion that the whole of the world could be powered by wind energy.
- New method to secure power supply. A brand new EU GARPUR may extremely change the power supply sector. Quite a loud announcement however, it has legs. The so-called ‘N-1 criterion’ currently ensures the electricity supply, even if a single system component fails. This criterion has governed transmission grid operations across Europe up until now. For four years, SINTEF Energy Research has been coordinating the EU project GARPUR. The project has now been completed and we have arrived at a new approach that may supplement or replace the N-1 criterion. Main objective of the GARPUR project has been to identify alternatives to the ‘N-1 criterion’ as the criterion states that a single failure or outage of a system component will not result in power supply interruptions to customers. The method proposed by the GARPUR project attempts to address this weakness using a risk-based approach that seeks to identify a socio-economic optimal security of electricity supply. Using this approach, security of supply can be differentiated and money saved by making security of supply more adequate from a socio-economic perspective. TSOs are provided with information that enables them to balance their costs against the societal benefits of the various measures available to them. The approach has been tested using pilots and case studies carried out by the TSOs. The results have been promising.
- $ 600 bln collapse. The biggest stock collapse in world history has just occurred with Chinese PetroChina Power Company. Ten years after PetroChina peaked on its first day of trading in Shanghai, the state-owned energy producer has lost about $800 billion of market value. The analysts supposed PetroChina to become the world’s first trillion-dollar company. However, PetroChina in ten years costs about 200 billion and the experts are convinced the situation will only get worse. By the way, let`s imagine the scope of $800 bln. Actually it is possible to buy the whole Italy`s stock market, to wrap the Earth with 100$ notes 31 times and it is even more that the Switzerland’s GDP. A number of different reasons influenced the stock slump however throw in oil’s 44 percent drop over the last 10 years and changes in Chinese economic sector are main reasons. Moreover, Chinese government agencies have the ambitious plans to promote electric vehicles, which hit the PetroChina horizons in future. As well, it serves as a simple signal for the fossil fuels sector.
- Science vs extreme weather. A research team led by scientists at Pacific Northwest National Laboratory explored how well statistical models could predict grid stress based on weather conditions in a particular region. Scientists found one type of statistical model provided predictive value and was easy to interpret.
The electricity sector develops contingency plans so that the grid is reliable even during periods when it is stressed by extreme weather events such as heat waves. Industry planning and operations teams could use the novel statistical techniques developed through this research to better understand and predict grid stress in the context of evolving electricity infrastructure configurations and environmental conditions.
The results also provide insight into the development of next-generation modeling and analysis tools to represent interactions between energy and Earth systems
Researchers constructed statistical models based on the weather variables that tend to give rise to grid stress. They used 10 years of high time-resolution electricity load and pricing data from 16 zones in the PJM (Pennsylvania-New Jersey-Maryland) Interconnection (a regional transmission organization), along with observed weather data from the same time period.
Assuming that data are available, the methods presented in this work could be extended to other regions or used to project potential changes in grid stress associated with future climate and infrastructure scenarios.
5. Electricity reforms affect the doing business. India has for the first time moved into the Top 100 in the World Bank’s Ease of Doing Business global rankings on the back of sustained business reforms over the past several years. How come? An analysis of the just released World Bank Group report reveals how strong reforms implemented in the powerdistribution acted as a major boost. “India performs well in the areas of Getting Electricity, Protecting Minority Investors and Getting Credit,” the Bank said in a statement. “The time to obtain an electricity connection in Delhi has dropped from 138 days four years ago to 45 days now. The time taken for getting the is in stark contrast to 136.4 days for South Asia, 79.1 days for OECD high-income countries and 10 days for the best performer UAE. India places in 29th place in the global ranking on the Getting Electricity indicator”. The bank also gave India high rankings on other parameters measuring quality power – total duration and frequency of outages per customer per year; mechanism for monitoring outages; mechanisms for restoring services; regulatory monitoring; financial deterrents aimed at limiting outages; and communication of tariffs and tariff changes. Actually, the report recognizes India as one of the top 10 improvers in this year’s assessment, having implemented reforms in 8 out of 10 Doing Business indicators. India is the only large country this year to have achieved such a significant shift.
