Net Metering is a rate that promotes renewable resource development by providing customers who generate some or all of their electricity using renewable resources credits and offsets that exceed utility cost savings for the power they generate.

Eligible Sources

Commercial - In addition to wind and solar, other eligible sources more suited for larger scale development include biomass, solar and solar thermal energy, wind energy, kinetic energy of moving water, including all of the following: waves, tides, or currents, water released through a dam, geothermal energy, municipal solid waste and landfill gas produced by municipal solid waste.

Program Generation Size Limits

Renewable installations other than methane digesters cannot exceed 150kW of aggregated capacity and methane digester installations cannot exceed 550kW.

Customer Specific Generation Size Limitations

In addition to staying within the program limitations, your customer generation may not exceed the size required to generate your annual needs.

Annual needs are established based upon one of three methods:

1. If historical data is not available the customer and Detroit Edison will mutually agree upon the customer’s energy needs.
2. Customer’s energy needs are set at the previous 12 months of actual energy usage in kWh for customers without a demand component in their rates. (Typically residential and small commercial customers).
3. If 12 months metered demand in kW data are available (typically large commercial and industrial customers) the size of a qualifying unit is limited to the smaller of the program generator size limit or the maximum site demand in a 12 month period.
