Gas Grid interplay with electricity grid. Spot on Efficient Operation During Peak Times and Heat Waves. In today’s interconnected energy landscape, the interplay between gas and electricity grids is more critical than ever. As we face increasing demand during peak times and heat waves, optimizing the operation of both grids becomes essential for ensuring reliability, efficiency, and sustainability. Understanding the Interconnection The gas grid supplies natural gas for electricity generation, while the electricity grid facilitates the transmission of power to homes and businesses. During peak demand periods, particularly in extreme weather conditions, the synergy between these two systems can significantly enhance operational efficiency. Challenges During Peak Times Heat waves lead to heightened electricity demand due to increased use of cooling systems. Simultaneously, natural gas often plays a pivotal role in electricity generation. This dual reliance can strain both grids, leading to potential supply disruptions and increased costs. Exploring Key Strategies for Efficient Operation: 1. Flexibility Services: The Cornerstone of Grid Resilience: Flexibility services—such as underground gas storage (UGS), demand response programs, and dynamic pipeline capacity allocation—are vital for balancing supply-demand imbalances during extreme weather. UGS facilities enable rapid injections/withdrawals to meet sudden spikes in gas-fired power generation demand. Concurrently, demand response initiatives incentivizing industrial consumers to curtail non-critical loads during peak hours reduce strain on both gas and power grids. 2. Role of Effective Dispatching: Coordination is Key: Real-time, data-driven SCADA dispatching is critical to minimize costs and prevent curtailments. Advanced predictive analytics allow operators to forecast demand surges and optimize pipeline flows. Crucially, coordination between gas and power system operators ensures that gas-fired generation units receive uninterrupted supply while avoiding pipeline pressure imbalances. For instance, co-optimization frameworks—where gas and electricity markets are cleared jointly—reduce operational risks and costs by up to 15% during heat waves. 3. Optimized Supply-Demand Management: Thermal Profiles Matter: Gas-fired power plants exhibit reduced efficiency during high ambient temperatures (>35°C), as turbine output and heat rate degrade thermally. Studies show a 10–15% decline in generation efficiency under heat stress, increasing Gas consumption and operational costs. To mitigate this, operators must prioritize: Preemptive maintenance to ensure peak efficiency. Inlet air cooling systems to offset thermal losses. Simultaneously, industrial loads—can be rescheduled or modulated ensuring critical infrastructure remains prioritized. #EnergyTransition #GasInfrastructure #GridResilience #ClimateAction #SmartGrids

From Problem to Opportunity Some might see it as a problem whereas some might see an opportunity. Now putting in context of Pakistan Power System this is the average hourly load demand based on the actual recorded load demand of ISMO for Year 2024/25. We can see two distinct features huge drop in demand during solar hours thanks to DER penetration and large peak demand in evening hours. So can we turn this problem into an opportunity. Based on my understanding of CTBCM, current market participants would be => Generators => Suppliers/Traders => Bulk Power Consumers (BPCs) What if we extent this category to include two new participants say =>Virtual Power Plants (VPPs). Aggregators of distributed generation, storage, and flexible demand. Allowing them to sell aggregated energy or capacity to suppliers, traders, or even BPCs through bilateral contracts. =>Demand Response Aggregators (DRAs). Entities that pool flexible consumer loads and sell negative watts (reduced demand) as capacity or energy resources. Allowing then to turn consumption flexibility into a tradable resource. These new participants can allow reduction in steep net demand fall caused by solar generation from rooftops and embedded PV. Instead of curtailing solar or running thermal units inefficiently, VPPs can export surplus to nearby industrial loads through local trading arrangements. On the other hand, as solar output fades, demand spikes DRAs can activate flexible loads (HVAC, pumping, industrial processes) to temporarily reduce demand. Together, VPPs and DRAs flatten the load curve, transforming an operational challenge into a market opportunity. CTBCM already provides the institutional and contractual foundation. What’s missing is the regulatory recognition of flexibility as a market product. Introducing VPPs and DR Aggregators can provide a structured way to monetize flexibility, help reduce ISMO balancing costs and empowering consumers to become active market participants. #CTBCM #VirtualPowerPlant #DemandResponse #GridFlexibility #PakistanPowerSector #EnergyTransitionPakistan #learning
