OPERATIONAL

SUMMARY

JANUARY 1996 UNIT 1 Unit 1 generated 788,152 megawatthours (MWh) (gross) electrical power during January with a capacity factor of 92.04 percent.

Unit I was offline at the beginning of January as a result of a' forced outage that began on December 25 following a failure associated with the main generator exciter. The exciter was replaced and Unit I was returned

. to service on January 2.at 1016 EST.

The turbine was taken offline at 1358 EST that day for maintenance on various problems associated with the exciter replacement. Unit 1 was tied to the grid at 2133 EST on January 2.

. On January 6 the turbine was manually tripped at 0500 EST for turbine balancing following the exciter maintenance. Unit 1 was online at 1253 EST.

Unit I was taken offline at 1445 EST for additional turbine l

balancing and returned to service at 1944 EST on January 6, 1996.

Unit 1 was operating at 100 percent reactor power at the end of January.

UNIT 2 Unit 2 generated 885,230 megawatthours (MWh) (gross) electrical power during January with a capacity factor 103.82 percent.

There were no outages or power reductions of greater than 20 percent to report during January. Unit 2 was operating at 100 percent reactor power at the end of January.
