Working with an auto parts manufacturer in Michigan, 8MW load. They're currently on DTE's Schedule D-5 but I think they might qualify for D-6 based on load factor. Anyone familiar with the qualification differences between these two tariffs?
DTE large industrial rate Schedule D-5 vs D-6
Donna, D-6 typically requires higher load factor - I think it's 65% minimum for DTE. D-5 has lower demand charges but higher energy rates. If your client has consistent high load factor, D-6 could save significant money. What's their annual load factor running?
Load factor is running about 72% annually, peaks during second shift operations. Current bills are averaging $520K/month on D-5. Think it's worth running the numbers for D-6?
Absolutely worth checking. We moved a Ford supplier from D-5 to D-6 two years ago, saved them $180K annually. The key is making sure they can maintain that load factor - if it drops below 65% they get penalized. Get 24 months of interval data and model both rates.
