19 Steps for improving the availability  Ensuring availability of Critical spares and Consumables  Reduction of forced outages in number and time  Compressing the period of planned outages  Better preventive maintenance works  Personal involvement at highest level  Ensuring availability of skilled staff and specialists to supervise the breakdown/planned works round the clock  Capital Overhauls planned on condition monitoring basis instead of manufacturers recommendations  Ensuring availability of stand-by-equipment to avoid partial load operation of the unit

32 Effects of ABT & Merit Order dispatch on parameters  Though we have achieved very good parameters in respect of Heat Rate, Secondary oil consumption, availability factor, PLF and forced outage rate, it may not be possible for APGENCO to achieve such performance in future years under ABT/ Merit Order regime and considering ageing of the plants.  During this year for the last seven months, back down of Generation is 300 MU which works out to 2.31% of total generation. Now under ABT/ Merit Order dispatch, we have to reduce the load to the extent of 40% of rated capacity of the unit which will adversely affect the following parameters. 1. Increase in Heat Rate due to partial load operation. 2. Increase in secondary oil consumption as single mill operation has to be resorted, requiring oil support for stabilization of the flame. 3. Increase in Auxiliary consumption due to operation of Auxiliaries at partial load. 4. Forced outage rate will increase due to frequent variation of the load affecting the pressure parts
