Customers with onsite generation other than emergency generation take service under one of our MPSC-filed rates and, typically, a rider to the rate covering the impacts of operating onsite generation.
The three most common rates:
- Rate Schedule No. D1 Residential Service Rate, typically used by residential customers.
- Rate Schedule No. D3 General Service Rate, typically used by commercial customers.
- Rate Schedule No. D6 Primary Supply Rate, typically used by industrial customers.
The riders for non-emergency onsite generation:
- Standard Contract Rider No. 3 - Parallel Operation and Standby Service Rider 3 is available to most commercial and industrial customers. These customers must take standby service under the provisions of the rider unless otherwise exempted. Rider 3 is not available to residential customers.
- Standard Contract Rider No. 6 - Small Power-producing Facilities Rider 6 is available to most customers, including residential customers, who develop small power-producing facilities and sell electricity to DTE Energy. To qualify for this rider, the customer must obtain qualifying status from the Federal Energy Regulatory Commission.
- Standard Contract Rider No. 13 - Dispersed Generation Rider 13 is available to customers who generate at least 250 kW of capacity and desire a voluntary dispersed generation payment for operating their generation at the request of DTE Energy.
- Standard Contract Rider No. DG - Distributed Generation Rider DG is available to residential and commercial customers with onsite distributed generation of no more than 100 kW who wish to operate in parallel with the DTE Energy system.
- Standard Contract Rider No. 16 - Net Metering for Renewable Resource On-Site Power Producing Facilities Rider 16 is available to all electric customers operating eligible onsite generation. Rider 16 currently provides credits based on the customer's standard retail rates for generation the customer can use.
Auxiliary power provision of the standard residential rate was developed in the mid 1970's for residential wind and solar generation. Although that provision is available, any unit that would qualify for this option would also qualify for the newest Rider 16 option which provides much more benefit to the customer.
