Westar Energy crews were working to restore power after an outage Monday left more than 3,000 Topeka customers in the downtown and  East Topeka areas without electricity.

According to Westar Energy, four separate areas were affected by the outages, which were reported at 7:54 a.m.

Westar officials said the outages were caused by birds in a substation.

The largest area was bounded roughly by S.E. 15th on the north, S.E. Carnahan on the east, S.E. 24th on the south and S.E. Madison on the west.

A second area was bounded roughly by S.E. 2nd on the north, S.E. Alkire on the east, S.E. 15th on the south and S.E. Jefferson on the west.

A third outage area was bounded roughly by S.E. 6th on the north, S.E. Deer Creek Parkway on the east, S.E. 11th on the south and S.E. Golden on the west.

The fourth area was bounded roughly by S.E. 6th, S.E. 2nd, S.E. Arter and S.E. Highland, affecting 298 customers.

Power in some of the areas had been restored as of 9:45 a.m.

Power to all of the areas was expected to be restored by 10:15 a.m., which was 15 minutes earlier than the original estimated time of 10:30 a.m.
