More than 6,000 Duneland homes and businesses were without power--or with
only intermittent power--into the early evening on Tuesday, after a
transformer at the Dune Acres substation failed, the Northern Indiana Public
Service Company said.
NIPSCO spokesperson Kathleen Szot told the Chesterton Tribune today
that the first reports of outages were made between 2 and 2:30 p.m., after a
malfunction of some kind occurred in that transformer. “We still don’t know
why,” Szot said.
Normally, the affected customers would then have been routed through the
Chesterton substation, Szot noted, but several weeks ago an issue developed

Attempts were next made to route customers through a second backup source
but, given the extreme heat of the day and the load on the system, “the

At 5:40 p.m. NIPSCO’s power outage Website showed more than 2,000 without
power in Chesterton and more than 4,000 without power in Porter.
All customers, however, were back on the grid by 7 p.m.
Today the Website showed exactly one Chesterton customer without power.
Szot was hopeful that the Chesterton substation will be returned to service
by the weekend and said that it’s now being monitored on a 24-hour basis.
She also said that NIPSCO is aware of the “inconvenience” which outages
present to customers during hot spells.
