Quick question about AEP Ohio Schedule TOU-GS. The tariff says peak hours are 1:00 PM to 6:00 PM Monday through Friday, but does that mean 1:00:00 PM sharp or does the 1:00 PM hour count as shoulder? I have a customer with significant load at exactly 1:00 PM and need to know which rate applies. - Jim L.
Time-of-use periods - when exactly does peak start for AEP Ohio?
Jim, in my experience with AEP Kentucky, the peak period starts at the beginning of the stated hour. So 1:00 PM means 1:00:00 PM. But I'd call AEP Ohio customer service to confirm because utilities sometimes have different interpretations. - Oz F.
Most utilities I've worked with use the start of the hour as the transition point. So 1:00 PM to 6:00 PM means the 1:00 PM hour (1:00-1:59 PM) is peak rate, and peak ends when the 6:00 PM hour starts. But Oz is right - call to confirm because some utilities are weird about this. - Claude B.
Check your customer's actual bills from previous months. The interval data should show exactly how AEP is billing each hour. That's the definitive answer rather than trying to interpret tariff language. - Clyde N.
Good call Clyde. Looked at the interval billing detail and confirmed that 1:00 PM hour is definitely billed at peak rate. The transition happens right at 1:00:00 PM. Thanks everyone. - Jim L.
