Omaha manufacturing client on OPPD Schedule P (standard). Their interval data shows consistent 400-500kW load from 6am-3pm weekdays, drops to 80kW evenings/weekends. Thinking about TOU Schedule T. Anyone run the numbers on OPPD TOU vs standard?
Analyzing OPPD load profiles for TOU rate optimization
OPPD Schedule T has on-peak 11am-7pm weekdays June-Sept. If your client can shift some load to mornings or evenings, could save significant money. Need to calculate demand charges too though.
Richmond client switched from Dominion's standard to TOU. Saved $1,800/month by running major equipment before 11am and after 7pm. Key is having operational flexibility.
Built a spreadsheet model for these comparisons. Takes interval data and calculates costs under different rate schedules. Happy to share if interested. Norfolk Dominion client saved 23% switching to Schedule 25.
Barbara that would be incredibly helpful! Can you post the spreadsheet or email it? My client is very interested in the potential savings.
Sent you the model via email. Remember to verify current tariff rates - utilities update them quarterly. Also check minimum demand provisions and ratchet clauses.
TOU rate analysis using actual interval data is one of the highest-value services we can provide clients. Often saves 15-25% on electric bills with minimal operational changes. Make sure to model seasonal rate variations.
