Low Peak Frequency High Off-Peak Frequency Wide Frequency Fluctuation Damage to Generating Plants and Consumers’ Equipment Merit Order not followed - Optimizat n. Oppo r. Lost Perpetual Operational and Commercial Disputes

UFR Load Shedding - Ineffective for Tackling Contingencies Over-drawal in Low Frequency Reluctance to Back-down Governor Action Supressed on Most Units  No Spinning Reserve  No Frequency Response Inadequacy/Low Availability of Generating Capacity : Widening Gap Reactive Power Drawals  Back-log in Capacitor Installation

Regional Energy Accounting In Daily/monthly MU, Disregarding TOD And/or System Situation (Freq) Unscientific Tariff Structre  No Disincentive for Hurting the Grid  Conflict With Merit Order Inappropriate Criteria for Judging Plants’ Performance Compounding effects of frequency fluctuations No formal Scheduling Process for Fixing Datums for Generation and Drawal Levels No Clear Demarcation of Scheduling and Despatch

 Incorporation Of Effective Automatic Load-shedding  Maximization Of Generation During Peak- load Hours And Load Curtailment Equal To The Remaining Generation Deficit  Backing Down Of Generation To Match The System Load Reduction During Off-peak Hours  Putting All Generating Units On Free- governor Mode Operation  Installation Of Capacitorss To The Required Extent  Absorbtion Of Vars During Off-peak Hours
