Apart from the familiar content relating to structural terms in the industry, power plant, grid and integrated supply system terms, energy and capacity terms and terms from the stock exchanges and trading markets now also newer terms from the immigrant energy transition and the global initiative to phase out fossil energy sources.
Life Cycle Management of Buildings and Structures in Industrial Facilities and Power Plants
This VGB-Standard is applicable to structural works in new-build, existing industrial facilities and power plants. Its focus is primarily on structural engineering systems which ensure load-carrying capability, serviceability and durability.
Structural Design of Cooling Towers
VGB Standard on the Structural Design, Calculation, Engineering and Construction of Cooling Towers.
Failures and Forced Unavailability of Power Plants (Henk C. Wels)
Power plants are not functioning to the fullest 100 % of the time. Maintenance and inspection of some components require them to be off-line in time, however, this can be planned such that customers continue receiving power from the electrical grid, steam or district heating from other plants. Unplanned outages due to failures or external conditions may cause surprises and can lead to situations in which the demand is not satisfied at short term at large costs.
VGB-Standard KKS. Pocketbook
The "KKS Pocketbook" (3nd revised and extende edition 2020) is an abridged version (extract) of the publication VGB-S-811-91-2020-09-DE-EN “KKS – Identification System for Power Stations”. The handy 148-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.
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
