Tampa office building switched to competitive supplier 6 months ago. TECO still handles delivery at $0.042/kWh. Supplier charges $0.078/kWh for generation. Problem is the old bundled TECO rate was $0.095/kWh total. Now paying $0.120/kWh combined. What am I missing?

TECO delivery vs competitive supply math not adding up
Kevin - sounds like you're comparing apples to oranges on rate classes. The bundled TECO rate might have been a different rate schedule than what they're using for delivery-only service. Check if they moved the customer to a higher delivery rate class when they switched to competitive supply.
Grace is probably right. I see this in Indiana with Duke Energy. When customers switch to competitive supply, Duke sometimes moves them to a less favorable delivery tariff. Compare the rate schedules carefully and file complaint if the switch was improper.
Update: Grace was exactly right. TECO moved the account from GS-1 bundled service to DS-1 delivery service, which has higher demand charges. Filed complaint with Florida PSC and got the rate schedule corrected. Savings now showing as expected.
