Flexible coal-fired power plants – German experience sought after at GIZ workshop in Beijing
The "Technical Solutions for the Flexibilisation of Coal-Fired Power Plants – Experiences from Germany" workshop took place in Beijing on June 9, 2017. It was jointly organized by the Chinese Electric Power Planning & Engineering Institute (EPPEI) and the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. In addition to VGB, representatives from Durag, Mitsubishi Hitachi Power Systems, RWE, Siemens, Steag Energy Services, VPC and Wallstein reported on their experiences with flexible power plant operation. The central message conveyed by the speakers was that the implementation of measures to make plants more flexible is less of a technical challenge than it is a commercial one. Stable framework conditions and a market design that honors flexibility are elementary prerequisites for sustainably transforming the energy system.

Recommendations for thermal/mechanical generator protection
To detect incipient damage to generators in power plants, protective equipment is installed. For electrical protection, in 2012 VGB published recommendations in the VGB-Standard VGB-S-025 “Electrical Generating Unit Protection”. The VGBStandard in hand, VGB-S-164-11, shows the protective measures that can be taken when thermal limits are exceeded or leaks and other malfunctions occur. These protective measures relate to so-called thermal/mechanical generator protection and cover generators for thermal power plants, hydroelectric power plants and wind turbines.
Document Designation for Energy Supply Units
Documents should be quickly available for certain tasks. To achieve this, a designation of documents with identifying and classifying information is necessary. Essential parts of the designation of documents are statements about the object represented and the characteristic content of information.
Analysis of Unavailability of Power Plants
The report provides information about weak points of equipment and power plant systems. VGB is analysing the annual unavailability (UA analysis) in order to identify the root causes, i.e. those systems causing unavailability to be able to upgrade such weak equipment.
Media Information 2017
The Media Information for the technical journal "VGB PowerTech" and other event-publications of VGB are now available for download.
Monitoring, limiting and protection devices on gas turbine systems
Monitoring, limiting and protection devices must satisfy stringent requirements in order to ensure safe and reliable operation of gas turbine units. The revisied VGB-Standard aims at considering the state-of-the-art and the current codes of practice and ISO and VDMA standards. This standard applies to stationary gas turbines (single-shaft and multi-shaft turbines) used to drive generators and other machinery.
Standards for professional leadership behaviourVe
Rather than sharing generally known theories and fundamentals on leadership behaviour, the VGB-Standard VGB-S041 is meant to serve as a basis for operator-specific requirements for leadership behaviour and focus content-wise on essential tasks of managers in day-to-day business.

Facts and Figures
Nuclear Power Plants
The European nuclear power plants generate more than 30% of the electricity need. Thus the CO2 load of the atmosphere is reduced by over 900 Mio. tons (if replaced by coal fired power plants). VGB PowerTech and the committees of the department „Nuclear Power Plants“ are dealing with all issues concerning a safe and economical operation of NPPs.
Power Plant Technologies
The competence area “Power Plant Technologies” is the communications platform for all questions concerning the technology and operation of all power plant types, and covers all technical areas from boilers and turbines to I&C systems. The focus is on both short-term issues relating to daily operation and long-term, strategically oriented topics.
Renewables and Distributed Generation
The committees related to "Renewables and Distributed Generation" are dealing with all technical and economic issues concerning the use of renewables and decentralized generation technologies
In Europe hydropower is not only an indispensable renewable source but it is still the frontrunner in renewable energy with an annual electricity production of more than 375 TWh, as approximately 41% of the renewable energy is based on hydropower. For more than 20 years an exchange of experience of the leading companies organized by VGB PowerTech is taking place on an expert level regarding technical and strategic topics.
The utilisation of wind power is playing an important role in order to meet the targets of the European Union within the Climate and Energy Package by 2020. By the end of 2016 the total installed capacity in the EU-28 amounted to 153,730 MW and worldwide to 486,749 MW. For more than 16 years an intensive exchange of information and experience to improve the efficient operation of wind power plants organized by VGB PowerTech is taking place. In this context, the requirements of the wind power plant operators are highlighted. The companies are mainly interested in cooperation to push forward standardisation (best practice) and to incorporate operator interest in the different user groups.
Power generation from biomass is a crucial part of transforming the global energy supply structure towards a sustainable energy future. Currently 167 TWh electricity and 855 TWh heat are generated from Biomass in Europe. Therefore Biomass has a share of 18.6% in renewable electricity generation and 87% in renewable heat generation. Since 2002 VGB has provided a growing platform for owners and operators of biomass power plants for sharing experience and knowledge at a high expertise level.
Environmental Technology, Chemistry, Safety and Health
The Competence Area „Environmental Technology, Chemistry, Safety and Health“ focuses on important general issues of power and heat generation. Its specialised committees offer the platform for the necessary exchange of experience and the forming of opinion of the branch for the respective specialists in the member companies
