In the focus: Dispatchable generation for flexibility in the energy system
A high degree of system flexibility is required to optimally integrate variable renewables like wind and photovoltaics (PV) into the energy system. This flexibility is mainly provided by four options: grids, storage- and sector coupling technologies, demand-side-integration and dispatchable generation. Currently the latter is the most important of these four options. Therefore, VGB published its Flexibility Page which focuses on publications, studies and VGB Standards all dealing with the flexible operation of power generation plants.

VGB CONGRESS - Innovation in Power Generation
4/5 September 2019 in Salzburg, Austria
Innovations in power and heat supply are the central themes for the VGB Congress. Topical political, strategic and energy sector related issues will be discussed in the plenary session on the first day of the congress.
Chemistry in Power Plants
23/24 October 2019 in Würzburg, Germany
The meeting place of international power plant chemistry! The following major items will be presented at the conference: Conditioning of water steam cycles and cooling water cycles; Methods of water preparation and waste water treatment ...
Digitalization in the Wind Industry
23/24 October 2019 in Vienna, Austria
Digitalization will enable wind farm operators to carry out better diagnosis of system performance, increase asset availability and thus reduce total costs. The main topics of this event will therefore mainly deal with the optimization of wind turbine operation.
5/6 December 2019 in Berlin, Germany
For mercury removal the operators of coal-fired power plants have a great challenge to meet the new emission limit values, which will become mandatory in the next years. Therefore, VGB offers a platform for an international exchange of ideas and experience.

VGB-Standard KKS. Pocketbook
The "KKS Pocketbook" (2nd revised and extende edition 2019) is an abridged version (extract) of the publication VGB-S-811-01-2018-01-EN “KKS – Identification System for Power Stations”. The handy 128-page brochure supports the decoding of KKS codes, one of the world's most widely used key systems for the designation of equipment and components in power generation.
Acceptance Test Measurements and Operational Monitoring of Air-Cooled Condensers under Vacuum
This guideline is meant to provide a standardized basis for acceptance and operating tests of air-cooled water steam condensers. Its scope of application is limited to the testing of the condenser itself and the exhaust steam duct up to the terminal point of supply.
Acceptance Test Measurements and Operational Monitoring of Water-Cooled Surface Condensers
More than twenty years ago, in 1994, the first edition of this standard was published in response to the rapid technological development and the growing importance of condensers in plant construction.
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.

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.
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
Technical services are an integral part of VGB PowerTech’s work. They are to be regarded as an enhancement to the services for our members and cover all aspects of engineering and operation in power plants. These services are used by members worldwide to achieve sustainably safe, fault-free and cost-effective operation
