Flexible operation of coal-fired power plants in India: Workshops in Kolkata and Ahmedabad

Representatives of the VGB and its member companies exchanged ideas with Indian industry experts about the need for flexible power plant operation and what options are available. The meetings took place in West Bengal and Gujarat.

More than 160 participants joined the workshops that took place in Kolkata and Ahmedabad in February. This number far exceeded the expectations of the organizer, the Excellence Enhancement Center (EEC). The Indian partner organization of the VGB organized these events with the aim of sensitizing the Indian energy industry to the need for flexible power plant operation for coal-fired power plants and to present promising technical and organizational measures.

In addition to the VGB, the member companies RWE, Steag and Siemens presented their experiences, which they gained in international projects related to the flexibilization of thermal power plants. In addition, the state electricity generators – West Bengal Power Development Corporation Limited and Gujarat State Electricity Board – stated that they have started investigating flexible power plant operation and have already carried out according test runs in their power plants. Representatives of the private power producer Adani Power Maharastra Ltd also pointed out the particular challenge of operating thermal power plants both flexibly and profitably.

Both workshops were organized under the auspices of the Indo-German Energy Forum (IGEF) with the support of the Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ). As part of the IGEF activities, the VGB is working with the EEC on other project schemes related to flexible coal-fired power plants.

Rules of Application for Fly Ash and Bottom Ash for Concrete in Germany - New edition of MVV TB published

The Model Administrative Provisions - Technical Building Rules (MVV TB) was first published on the website of the German Institute for Building Technology (DIBt) on 31 August 2017. It contains, among other things, the requirements for hygiene, health and environmental protection applicable to concrete products and building components containing fly ash and bottom ash. Details can be found in the "Requirements on constructions regarding impact on soil and water” (Anforderungen an bauliche Anlagen bezüglich der Auswirkungen auf Boden und Gewässer (ABuG). These rules essentially represent the requirements of the former national approvals (abZ), which are currently used as technical proof of environmental compatibility. In addition, Annex A 3.2/3 sets out the exemption rules for fly ash from coal only and those from the co-combustion of up to 5 wt.% of municipal sewage sludge.

The MVV TB is reviewed and updated at regular intervals. Following the consultation procedure in spring 2019, DIBt published MVV TB 2019/1 on 15 January 2020. The requirements of the ABuG have remained virtually unchanged. However, Annex A 3.2/3 was deleted. This was due to objections in the consultation procedure which concerned the legibility of the regulations. However, the exemption rules have been fully transferred to the individual chapters on construction products containing fly ash.

TW-103Ae - Analysis of Unavailability of Power Plants - Now available as eBook!

The Technical-scientific Report Analysis of Unavailability of Power Plants for the period 2009 to 2018 is now available. In addition to the power plant availability parameters, the performance of key systems and equipment affecting the unavailability of power plants is reflected. An unavailability analysis is done annually in order to identify such systems and equipment, and to monitor or retrofit these parts in order to improve power plant performance. The systems and equipment are specified according to the power plant identification system (KKS). The current report comprises performance indicators for 293 power plant units, evaluates around 80,000 incidents and provides some new features:

• International focus,
• new availability charts considering quartile values,
• new nominal capacity cluster.
