18. ABT Balancing Market UI mechanism takes care of the deviations in an inherent way Price based on frequency reflecting load generation balance in the grid No negotiations, no bidding. Flexible-anybody can inject or draw. ISO purchases balancing power and despatches Price of balancing power based on bids which reflect notional market conditions Requires Exchanges, complicated procedure and involves cost in setting up of computerised systems

19. Inadvertent exch- anges priced based on frequency & price is known to all No gaming UI Pool allows frequency variation between 49.0 and 50.5 Hz. Complex mechanism for pricing inadvertent exchanges Gaming is possible Suitable in systems where frequency has to be maintained close to nominal ABT Balancing Market
