In addition, it will serve as a tool for peak load management and frequency stabilization, crucial for maintaining the stability and reliability of our energy supply. This project is aligned with India's renewable roadmap, which aims to increase the share of renewable energy in the country's energy mix. By implementing a BESS, we are contributing to this goal and making a positive impact on the environment. As a responsible and sustainable company, GAIL is committed to decarbonizing our operations. The implementation of a BESS at Vijaipur Complex is a step towards achieving this goal and reducing our carbon footprint. Thank you for watching this portion of our training video. We hope this has provided a better understanding of the objectives and importance of the pre-tender conference for the design and implementation of a BESS at GAIL Vijaipur. Stay tuned for the rest of the presentation to learn more about the details and benefits of this project..

[Audio] Slide three of our presentation focuses on Load Assessment and Demand Forecasting in relation to the Battery Energy Storage System (BESS) at GAIL Vijaipur. Accurate assessment and forecasting are crucial in determining the size and capacity of the BESS. This slide displays the components that contribute to the overall load estimation, including the exclusion of the Gas Turbine Generator, the Hydrogen Generation Plant, Small-Scale LNG Plant, GTC Electric Drive Conversion, Mounded Bullets, and the Hydrogen Compressor. These components result in a total estimated load of 23.1 MW, representing the projected peak demand the BESS will need to handle. It is essential to thoroughly understand the load assessment and demand forecasting for GAIL Vijaipur as we move forward with this project. The next slide will provide further information..

[Audio] Today, we will be discussing slide number 4 out of 17, which focuses on the power requirements for the project. GAIL Vijaipur has a Load Plant Load of 9.5 MW, a H2 Generation Plant of 10.4 MW, and a SSLNG of 0.4 MW. This brings the total projected peak demand to 23.1 MW. In addition, we have mounted bullets for 0.5 MW and a H2 Compressor skid for 0.3 MW. These power needs must be carefully considered and planned for in the design and implementation of the BESS. Let's move on to the next slide for more detailed information..

[Audio] Slide number 5 out of 17 discusses the renewable energy generation profile and the need for a Battery Energy Storage System (BESS) at GAIL Vijaipur. The source of our renewable energy comes from various installations with a total capacity of 64.05 MW, including ground-mounted solar, floating solar, and hybrid renewable energy power purchase agreements. These sources ensure an average availability of approximately 37.4 MW. However, due to the intermittency of renewable energy sources, a BESS is necessary to efficiently manage and store excess energy, providing a more reliable and consistent energy supply for GAIL Vijaipur. Stay tuned for more information on the upcoming pre-tender conference..

[Audio] We are currently on slide number 6 out of 17, titled "Installed RE and Contract Demand." The slide contains information on the pre-tender conference for the design and implementation of a BESS at GAIL Vijaipur. Let's focus on the numbers on this slide: the current installed RE capacity is 64.05 MW, and the contract demand from MPEB is 23.5 MW. The long term hybrid RE PPA, or power purchase agreement, is for 21 MW. The effective output of the project is 37.4 MW, including 10 MW from ground-mounted solar panels, 1.8 MW from rooftop solar panels, and 7.75 MW from floating solar panels. This diverse mix of solar energy sources is important for a sustainable energy portfolio. Stay tuned for more valuable information in the remaining slides..

[Audio] Today, we will be discussing slide number 7 out of our 17 slides. This slide focuses on the solar generation variability and its impact on our project. The solar irradiation analysis has shown that the generation window for solar-based assets is limited to the hours of 08:00 to 18:00, with peak output occurring between 12:30 and 13:30. This means that during these hours, we can expect a cumulative daily generation from solar-based assets of approximately 135.34 MWh. To ensure the success of our project, we must consider a 20% capacity utilization factor (CUF) for our solar assets. This will help us maximize the potential of our solar generation. However, there is a potential issue with curtailment. Without proper management, the midday surplus of solar energy may cause reverse power flow. This is where a BESS, or Battery Energy Storage System, comes in. By storing excess energy during peak hours and releasing it during off-peak hours, the BESS can help us avoid any reverse power flow and maximize the use of our solar energy. In summary, our daily solar output is 135.34 MWh, with a generation window of 08:00 to 18:00. Outside of these hours, there is no solar availability. It is important to keep these factors in mind as we move forward with the design and implementation of our BESS at GAIL Vijaipur..

[Audio] We will discuss the importance of Battery Energy Storage Systems (BESS) for our GAIL Vijaipur Plant. The plant is expecting excess energy and we are seeking ways to efficiently store it. BESS technology allows us to store energy during peak power generation and use it during off-peak periods such as evenings and nights. This balances the distribution of electrical energy, as shown in the graph. This technology is crucial for our plant, as the load demand varies throughout the day and we have added 20 MW of captive solar power, requiring a long-term PPA to meet our grid demand. Implementing a BESS will effectively manage our energy resources, reducing our reliance on the grid and resulting in cost savings and a more sustainable energy solution. Moving on to the next slide, we will explore the technical aspects of BESS in more detail..

[Audio] Today, we will be discussing the importance of BESS, or Battery Energy Storage Systems, in addressing the intermittent nature of renewable energy sources. Renewable energy sources, such as solar panels, can produce more electricity than the demand during certain hours of the day. However, without proper storage, this excess energy goes to waste. This is where BESS comes in. BESS plays a crucial role in storing surplus energy for later use. To make the most of this excess energy, a BESS can be used to store it for later use. For example, if our solar panels produce more electricity during peak hours than the demand, the excess can be effectively stored in the BESS for later use. In this specific scenario, there is a surplus of approximately 6 MW for 4 hours, from 11am to 3pm. This means that during these 4 hours, the BESS can provide an additional 6 MW of energy to meet the demand. By utilizing BESS, we can ensure that excess energy is not wasted and can be used when needed. This is not only beneficial for the environment, but also for the efficiency and sustainability of our energy systems. In the next slide, we will dive deeper into the technical aspects of BESS. Stay tuned for more valuable information on this important topic..

[Audio] Slide 10 presents the proposed topology for the BESS at GAIL Vijaipur. This slide illustrates the different components included in the system, such as solar PV arrays, 33KV GIS, step-down transformer, PCS, battery containers, and SCADA and EMS systems. The solar PV arrays will be the primary source of energy, converted to AC/DC power by the PCS. The batteries will serve as storage and supply power when needed. The EMS and SCADA systems will allow for efficient monitoring and control of the entire system. This topology was carefully designed to optimize the use of renewable energy and provide a reliable energy storage solution for GAIL Vijaipur. Moving on to the next slide, we will delve into the technical specifications and requirements for this project..

[Audio] Slide number 11 of our presentation covers the control philosophy of the Battery Energy Storage System (BESS) at GAIL Vijaipur. The charging algorithm will only be activated during times of confirmed excess solar energy, with priority given to critical loads before charging the battery to ensure essential systems are not affected. To protect the battery's longevity and efficiency, the charging limit is capped at 90% of its maximum state of charge. The discharge algorithm will be triggered by the time of day peak price schedule, state of charge threshold, and load surges, with the system maintaining its output until the reserve threshold of 10% state of charge is reached. The Energy Management System (EMS) includes features such as optimizing the state of charge through weather forecast and load analytics, real-time communication with the State Load Dispatch Center (SLDC) for demand response, and an inbuilt load shedding logic for unexpected drawdown. The EMS also has a calendar-based scheduler for maintenance purposes. Thank you for watching this slide and stay tuned for the rest of our presentation..

[Audio] Slide number 12 in our presentation on the design and implementation of a BESS at GAIL Vijaipur will discuss the control philosophy and sizing methodology. The charging window analysis determined the BESS capacity based on an average surplus of 6 MW at GAIL Vijaipur. The 4-hour charging window from 11:00 AM to 3:00 PM allows for a maximum charge of 6 MW. The energy capturable is calculated by multiplying 6 MW by the 4-hour window, giving a total of 24 MWh. For load support, the BESS must discharge 48 MWh to meet the 12 MW target during the night from 6:00 PM to 10:00 PM. This information is crucial for the design and implementation process and will be discussed further in the upcoming pre-tender conference. Slide number 13 will continue the discussion..

[Audio] Slide 13 of our presentation on the technical specifications of a BESS battery will discuss the various parameters and specifications of the battery. The battery chemistry is lithium iron phosphate, known for its stability and safety. The nominal energy of the battery is 25 MWh, with a discharge power of 6 MW for a steady and efficient energy supply. The battery has a depth of discharge of over 90%, providing flexibility in managing energy usage. The round trip efficiency is over 85%, resulting in a more cost-effective system. The PCS conversion efficiency is over 96%, ensuring minimal energy losses and a reliable system. The battery's estimated system life expectancy is 6000 cycles or 16.5 years of operation, demonstrating its durability and longevity. Precision HVAC and redundant enclosures will control the battery's thermal temperature. The battery will be housed in modular ISO containers, providing a secure and customizable environment. In case of fire emergencies, our system is equipped with a clean agent fire suppression system. The control interface will allow for efficient monitoring and management of the battery..

[Audio] We are currently on slide number 14 out of 17, going over the protection, safety, and compliance measures for the design and implementation of a BESS at GAIL Vijaipur. Safety is essential in any project, particularly when dealing with electrical components. To ensure the safety of our employees and the community, we have implemented multiple protection measures, including safeguards for electrical over-voltage, under-voltage, over-current, earth fault, and surges. Our design also takes into consideration the risk of thermal over-temperature, which we have addressed through the inclusion of cutoffs, redundant cooling fans, and thermal sensors. This not only protects the BESS from overheating, but also prevents potential dangers. Additionally, we have fire safety measures in place such as heat and smoke detectors, an automatic isolation system, and a Novec/Aerosol based suppression system in case of a fire. Communication is vital, which is why we have a dual-redundant fiber link and a secured Modbus over TCP/IP system for reliable and secure communication within the BESS. Cybersecurity is also a top priority, and we have taken all necessary precautions, including role-based access, firewalls, event logging, and encryption. We have also adhered to regulatory standards such as IEEE 1547, IEC 62933, MNRE norms, and CEA Technical Guidelines to ensure compliance. Thank you for your attention to this critical aspect of our project. Let's continue our discussion on this important topic by moving on to the next slide..

[Audio] This presentation focuses on the Implementation Roadmap and Conclusion. We are currently on slide 15 out of 17, where we will discuss the necessary steps before beginning the implementation process for the BESS project at GAIL Vijaipur. The first step is a pre-tender conference to provide a better understanding of the project and its requirements. This will also give potential vendors the opportunity to ask questions. We will then obtain necessary approvals and conduct a pre-feasibility study to determine the feasibility and potential challenges of the project. If necessary, we will hire a Project Management Consultant (PMC). Next, we will carry out Detailed Design Engineering for the electrical, civil, and control aspects of the project to ensure it meets all technical requirements and specifications. The tender will then be prepared and a Request for Proposal (RFP) will be released, including technical specifications and a Bill of Quantities (BoQ). Approval from the Department of Personnel (DOP) is required before floating the tender and selecting a vendor through competitive bidding, to ensure transparency and adherence to procedures. After vendor selection, Factory Acceptance Tests will be conducted on the PCS, BMS, and Battery Modules to verify if they meet required standards and specifications. Site mobilization, installation, and cable termination will be carried out once the equipment is ready, to ensure proper and safe functioning of the BESS. To monitor and control the BESS remotely, an EMS-SCADA integration with remote access will be implemented. Commissioning, protection relay testing, and load trials are the final steps of the implementation process to ensure efficient operation of the BESS. Training and documentation will also be provided to inform and prepare all involved parties. The project will be closed once these steps are completed..
