SUMMARY

The Unit began the report period operating at a nominal value of 100% output. The Unit continued to operate at a nominal value of 100% output until 1248 hours0.0144 days <br />0.347 hours <br />0.00206 weeks <br />4.74864e-4 months <br /> on 05/07/99 when output was reduced by approximately 2% to gain extra margin as a conservative measure in order to prevent a possible turbine runback during the re-scaling of Loop ill Delta-T / Tavg. Following completion of the re-scaling, the Unit was requested by Duquesne Light Company System Operations at 0311 hours0.0036 days <br />0.0864 hours <br />5.142196e-4 weeks <br />1.183355e-4 months <br /> on 05/09/99, to remain operating at approximately 98% output to load follow. The Unit continued to load follow at approximately 98% output uhtil it was retumed to a nominal value of 100% sutpdi at 0528 hours0.00611 days <br />0.147 hours <br />8.730159e-4 weeks <br />2.00904e-4 months <br /> on 05/09/99.
