(La Porte, IN) - Roughly 4,000 NIPSCO customers in La Porte yesterday experienced flickering lights.

According to NIPSCO, the problem lasted for about two hours during the afternoon before NIPSCO crews were able to fix it.

NIPSCO spokesperson, Tara McElmurry said an equipment failure within a power line that impacted multiple substations was to blame.

Mayor Tom Dermody said a number of people called City Hall to inquire about the problem. Service for customers impacted by the problem returned to normal about 4:30 p.m, according to NIPSCO.
