I&M has several PEV tariff options to help our Michigan customer save money on off-peak PEV charging. All options require a submeter between your electrical panel and Level 2 PEV Charger.
Most Michigan residential customers are on RS Tariff 015 and pay 14.5 cents per kWh of electricity at home, no matter what time of day. Specifically, under RS Tariff 015, you will have three RS-PEV options to choose from as summarized below.
We can help you choose which PEV option will work best for you once your incentive application is submitted and approved.
PEV Option 1 (Tariff 057) – Whole House Time of Day Rates
Under PEV Option 1, the on-peak rate of 21.046 cents per kWh applies from Monday – Friday, 7AM to 9PM and an off-peak rate of 6.591 cents per kWh applies for all other hours each week.
For the first 250 customers that select either Option 1 or Option 3 below, there will be no charge for the submeter.
Ideally, for PEV Option 1 to save you money, at least 60% of your whole house electrical consumption (kWh), including your EV charging, needs to be during the off-peak hours.
PEV Option 2 (Tariff 058) – Separately Metered PEV Time of Day Rates
Under Option 2, a $9.15 monthly meter fee is applied for the extra meter. PEV Option 2 is a good fit for customers where the Level 2 PEV charging location is great distance from their panel, making a sub-metered option difficult or more costly to install.
As with PEV Option 1, to save money, at least 60% of your whole house electrical consumption (kWh), including your EV charging, needs to be during the off-peak hours.
PEV Option 3 (Tariff 059) – Submetered PEV Time of Day Rates
This is our most common PEV option. Under Option 3, you pay the standard RS Tariff 015 rate of 14.5 cents per kWh during the day and a discounted off-peak overnight rate of 8 cents per kWh for PEV charging from 11PM to 6AM daily.
The $2.75 monthly submeter fee is waived for the 250 customers enrolled or if your monthly use is at least 250 kWh. This rate is effective for residential customers who can’t shift their electricity use to off-peak hours for the other options.
