FLEXIBLE OPERATION OF THERMAL PLANTS
+ 3 Exclusive Award Categories
India has achieved 165.94GW of renewable energy capacity till October 2022 and has set ambitious revised targets for renewable energies to 500 GW by 2030. India can successfully integrate 390GW of wind and solar generation by 2030, an increase of more than 40% above the current renewable energy trajectory, at a total system cost that is lower than that of the current trajectory. By making both electricity supply and electricity demand more flexible, India can achieve these higher levels of clean energy, creating a modern, low cost energy system, while reducing carbon emissions.
This requires a radical transformation of the energy system in India, as approximately 65 percent of existing installed capacity currently comes from thermal power generation. The increasing share of variable renewable energies will result in less operating hours as well as in flexible operation regimes of India's conventional mainly coal-fired – power plants. The Indian coal – which is the key source for the majority of coal-fired power plants in India – has some special properties which also have an influence on the flexible operation. While this is expected to lower carbon emissions and help meet the growing energy demand, the integration of renewables into the grid will be a big challenge. Renewable energy generation suffers from fluctuations, predictable and unpredictable, due to uncertainty in weather conditions. To accommodate such sharp variations in generation, there has to be a multi-pronged approach including cyclic operation of gas and hydro-based generation, use of existing pumped storage systems, development of pumped storage and battery storage, adoption of demand management measures and flexible operation of coal-based plants for the optimization of the entire power system.
The increased share of feed-in from fluctuating renewable energies – mainly wind and solar – results in complex challenges for the energy system. In addition to other options such as grid and demandside management, flexible conventional power generation plays a key role for ensuring adequate system stability. Therefore, existing coal-fired power plants need to adapt to a completely new operating regime.
Applicability: All coal based thermal power generating units owned or under control of the Central Government, State Government or owned by any private company, connected with the grid and to the load despatch centers.
Key Points: Units should be designed in a way that they comply with these regulations for the full range of ambient and environmental conditions prevailing at the site. These generating units should be capable of providing flexible operation as per the phasing plan specified by the Authority from time to time. Minimum power level of these generating units should be 40%. These generating units should have the ramp rate capability of minimum 3% per minute for their operation between 70% to 100% of maximum continuous power rating and should have ramp rate capability of minimum 2% per minute for their operation between 55% to 70% of maximum continuous power rating.
"A lot more literature about flexibilisation of thermal power plant exists around which is noteworthy. But it is more imperative to attend this important conference "Flexible Operation of Thermal Plants" to learn & discuss the technical challenges & understand latest notification in this current phase of Energy Transition & Decarbonisation"
The flexibility potential by means of I&C adjustments is significant because the level of automated and advanced controls leave room for improvements. Especially with respect to a fast and ecient start-up, manual interventions should be reduced to a minimum. In order to enhance the dynamic behaviour of the plant and to positively contribute minimum load and cycling operation, advanced unit control concepts such as condensate throttling and throttling of the extraction steam for the HP pre-heater are very beneficial. This modification helps fulfilling the requirement of providing 5 percent frequency control power.
The standard design and set-up of Indian coalfired power plants entails some favorable configurations for flexible operation – e.g. they are equipped with a high number of mills, tilting burners and frequency-driven fans and actuators. Due to the coal quality it is unlikely that Indian power plants are able to reduce the minimum load below 25 percent without any additional coal treatment. Therefore, a concept for homogenization and enhancing coal quality should be developed. Such a concept could include washing, blending, coal cleaning at site as well as online coal analysis.

Flexible power plant operation comprises three dimensions: low minimum load operation, short and efficient start-ups and shut-down and high ramp rates. Most measures for flexibility enhancement aim at low minimum load operation. This is very important for the provision of residual load and in times of low demand, it is more economic than shutting down the whole plant. The transformation from base-load to flexible operation is a change process that requires strong management and leadership, skilled employees and appropriate technology. There is no generic concept or single implementation plan for power plants, as each plant has its own specifics, technology requirements and site conditions. However, there are some actions and steps that need to be taken in order to tap the flexibility potential of a single plant.
The flexible operation of coal-fired power plants requires suitable technologies, skilled people and leadership with foresight. In addition, it needs to be recognized that this new operating regime implies a change process that can only be managed successfully with a holistic approach.
The Instrumentation and Control (I&C) system plays a crucial role for flexible operation. Plant status transparency, the availability of operating data, sophisticated data assessments and advanced controls are a prerequisite for operating a power plant with enhanced flexibility. Moreover, the I&C system is the link joining all aspects important for efficient plant operation. It should be in the focus of any flexibility project as the benefits and the cost effectiveness are unbeatable. With respect to further digitization, I&C optimization offers even more potential, by enabling efficiency and flexibility enhancements at the same time.
Flexible operation needs a holistic approach. The conference is designed to discuss strategies for a co-ordination amongst all the sources of generation and find a way out for the flexibilisation of the thermal power plants. Also, imphesise on regulatory interventions including revised tariff structure for the flexible operation of thermal power plants for deployment of this change process in existing power plants by addressing the following questions:
What procedures have proven successful for identifying and implementing flexibility measures?
What are the proven technical measures to adapt existing plants to flexible operation?
What are the consequences for the Operation & Maintenance (O&M) of the plant?
What are the requirements for the personnel? Which training are useful?
What are the tasks the plant management needs to address?
If you are interested in speaking at the conference we are inviting you to put forward your presentation proposal for review by our international conference advisory board. Please note that not all submissions can be accepted but all will be considered ahead of the final submission deadline.
