Together, we can create a clean energy future for Michigan. While DTE Energy does not install solar or other renewable energy generation systems for our customers, we have an important role to play in connecting your private generation system to the grid.
The Rider 18 Distributed Generation Program is available to DTE customers with qualified renewable energy on-site generation. Participants are compensated for electricity they send into DTE's distribution system (outflow) when they fulfill DTE's Renewable Resource requirements.
The program is limited to Category 1 and 2 renewable projects, or Category 3 for a methane digester (see a detailed table of project sizes). Customers with private generation systems are still connected to DTE's distribution grid. Your DTE bill will reflect charges for inflow in accordance with the rate schedule to which Rider 18 is attached and any credits generated by your system.

Installing a solar PV system is an important financial and environmental decision. To help our customers, DTE offers a Distributed Generation Impact Calculator that can estimate the financial impacts of installing a solar PV system.
While the Impact Calculator provides a general financial analysis, it's important to understand that the calculator uses assumptions and averages, so the results won't fully reflect the exact load profile or circumstances for each unique customer. The results of the calculations are not a promise or guarantee of a customer's actual financial impact. DTE is not responsible for the results or accuracy of those estimates.
You can sign in to your DTE account to automatically apply your average monthly usage data in the analysis.
The data will be applied automatically if you sign in to your DTE account, or you can average your last 12 months of usage listed on your monthly billing statements.
System size must be limited to no more than 100% of your electricity consumption from the meter the system is being attached to, and cannot exceed 150 kW of aggregate generation at a single site.

The calculator is designed to be an informational and educational tool only. When used alone, it does not constitute final, quotable results. The results are provided as a rough approximation of your bill.
The calculator uses the following assumptions and averages based on information available for the state of Michigan and the current construct of Rider 18 and is subject to change.
Battery usage is not considered in the results of the bill calculator. Adding a battery would result in a higher average cost of <$x,xxx>, assuming the battery is intended for backup rather than load management use.
Rate: If you sign in to your DTE account, the calculator will pull the rate at the selected location and meter. If you don't sign in, estimates are calculated based on the current Standard D1 Rate.
Solar panel output is used under the assumption that the inverter at the location would allow for the entered output amount.
Results are based on the assumption that customer energy usage is the same as it was before the installation of solar panels.
Average monthly usage is calculated from averaging the last available 12 months of data.
Capacity factor is assumed at 13%.
The calculator factors the annual rate of degradation of solar panels ay 0.5% per year. Source: National Renewable Energy Laboratory (NREL).
Interest rate is assumed as 3.99%.
Average electricity use throughout the day is assumed and may not match your actual usage.
The calculator factors in the Investment Tax Credits (ITC) when calculating costs, payback period and the return on investment.
If install cost is not inputted, the calculator will assume the cost of the solar installation based on current technology costs, ITC's, etc.
Understand your monthly electrical needs and research and review potential installers for your project.
When you're ready, contact several installers to gather quotes before signing a contract.
You can work with your installer to submit an application. Learn more about the interconnection process.
Our application status tracker keeps you in the loop.
After your application is approved by DTE, your installer has 180 days to install the system and upload the construction documents.
Learn more about the installation process
Once your system is installed and the construction documents are uploaded and approved by DTE, you will sign the Parallel Operating Agreement (POA). Once the POA has been signed and returned, DTE will perform a site visit to test and program your system.
After a successful site visit, DTE will turn on your system so it can begin generating energy. At times you may generate more electricity than you use, resulting in your system outflowing energy to DTE's distribution system. You then receive outflow credits on your bill that can be used to offset the power supply charges of the rate schedule to which Rider 18 is attached. For all inflow, you are charged the retail rate of the rate schedule to which Rider 18 is attached.
If the amount of outflow credit in a billing period exceeds the power supply charges, the excess outflow credit is banked in the excess generation bank and can be used in a future billing period to offset power supply charges of the rate schedule to which Rider 18 is attached. The excess generation bank carries forward and does not expire.
It will generally take one or two billing cycles for a customer's bill to reflect participation in the Rider 18 Distributed Generation Program and any outflow credits.
Inflow is the electricity the customer uses from DTE and its distribution system. Inflow is charged at the retail rate depicted on the customer's rate schedule to which Rider 18 is attached.
Outflow is the electricity generated by the customer's distributed generation project that is not used on-site and is instead sent to the distribution grid. Outflow is credited based on the power supply rate (less embedded transmission cost) of the rate schedule to which Rider 18 is attached.
Will I still receive a bill from DTE after I have installed my system?
Yes. Customers with private generation systems are still connected to DTE's grid and receive electric energy from DTE when their system does not produce enough power to meet their needs. You'll still receive charges according to your rate schedule for total inflow, including any fixed charges associated with the relevant rate schedule.
Will customers who install private generation systems still lose power if DTE's distribution system suffers damage, requires maintenance, or otherwise experiences a power outage?
If your system is equipped with a typical “grid following inverter”:
Yes. Inverters are designed to shut off if the utility loses power, which is required by national standards for safety purposes. Customers with generation sources not connected to the grid (e.g., those with backup generators and/or battery storage) may avoid power loss in such instances.
If your system includes a “grid forming” inverter and a transfer trip system (which is not common in Michigan):
Then your system may keep your devices running, so long as your system produces enough power to support your current needs. However, if you try to use more power than your private generation system makes, the inverter will turn off the power, until your demand is reduced. Obviously if you have a solar PV system prior to sunset the system will likely stop making enough power to power your home or business.
In either case, customers are NOT “off the grid” even while on the program. Private renewable generation systems taking service under the Rider 18 Distributed Generation Program will still be connected to a continuous source of electrical energy from DTE's distribution grid.

If you have questions, please contact the rates and billing hotline at (800) 482-8720, option #4.
Is my roof a good candidate for solar?
Your geographic location, the pitch of your roof and the direction your home faces all impact how much solar energy you can harvest.
Long periods of shade can affect electricity generation. Trees, chimneys and other buildings can make some rooftops a less-than-ideal place for solar panels.
Solar PV systems are a long-term commitment and can last 15 to 30 years. You will want to ensure your roof is in very good condition and will last the lifetime of the solar PV system. Not having a roof in sufficient condition may require you to uninstall and re-install the PV system during this time, thus adding to unexpected costs and PV system downtime.
Additional factors may exist that prevent rooftop solar power generation. An installer will thoroughly evaluate your home for solar compatibility.
We encourage you to do research as you would for any major project or purchase.
DTE does not provide installer recommendations, but Michigan Saves maintains a list of solar installers in the state. Meet with multiple contractors and be sure to review credentials.
The state of Michigan maintains a webpage to look up the current status of licenses. Both the general contractor and the electrician will require licenses to perform work.
In addition to online reviews, seek out recommendations from friends and neighbors who have installed solar at their own homes. Look for positive reviews at the Better Business Bureau.
Ensure that your installation includes a workmanship warranty (and thoroughly read it) so that you're covered if issues arise after your system is live.
Why are Rider 16 Net Metering customers being switched to the Rider 18 Distributed Generation program?
State laws mandated that the Michigan Public Service Commission (MPSC) phase out the Net Metering program and create a new distributed generation program. For DTE, these laws resulted in the implementation of the Rider 18 Distributed Generation Program in 2019.
DTE's existing Rider 16 Net Metering sites will be converted to the Rider 18 Distributed Generation Program upon reaching their 10-year anniversary in the Net Metering program. DTE will notify customers via email approximately 30 days prior to their rate conversion.
When switching to Rider 18 Distributed Generation, will Net Metering customers lose their Excess Generation Bank?
No. Customers converting to the Rider 18 Distributed Generation Program will receive a check for their Excess Generation Bank balance, if applicable, approximately 60 days after their conversion.
How does this affect a SolarCurrents contract?
Moving to the Rider 18 Distributed Generation Program does not affect SolarCurrents contracts. The SolarCurrents contracts are applied to the purchase of renewable energy credits for 20 years and will continue under the Rider 18 Distributed Generation Program.
Can a customer expand their existing project size and remain on Rider 16 Net Metering?
No. If a customer expands their renewable generation system, the entire system will be moved to the Rider 18 Distributed Generation Program, not just the expansion.
How will the Distributed Generation Program impact the customer's electric bill?
The impact to the customer's electric bill will depend on several factors, including energy consumption, generation, and system size. Interested customers can download this calculator and input inflow/outflow data to estimate the impact to their bill.
Can a Rider 18 Distributed Generation Program customer enroll in the MIGreenPower program?
Yes, a Rider 18 Distributed Generation Program customer can enroll in the MIGreenPower program as a simple and effective way to become a net zero carbon emissions customer. Under Rider 18 Distributed Generation, customers inflow electricity from the grid and receive credit for any outflow. As a result, Rider 18 Distributed Generation Program customers may be interested in “greening” all their energy.
In order to calculate their MIGreenPower subscription, customers will need to look at their annual inflow and outflow. Here is an example:
|Achieve Net Zero Emissions||kWh||Percent%|
|Total annual inflow||10,000||100%|
|Renewable energy from grid||1,500||15%|
|Total annual outflow||7,500||75%|
|Estimated Net Zero Percent for MIGP||10%|
|“Greening” all incoming energy||kWh||Percent%|
|Total annual inflow||10,000||100%|
|Renewable energy from grid||1,500||15%|
|Estimated Percent for MIGP||85%|
I purchased a home with a renewable electric generation system. What do I need to do?
First, you will need to transfer the electric service to your name by calling (800) 477-4747. You will then need to start a new interconnection application to transfer the system into your name. To start this process, follow this link to login to your dashboard and then click on "Start a New Project" button and follow all the necessary steps in PowerClerk. For a description of service, be sure to select "Change of ownership of a currently served location." For additional questions or assistance, please call the DTE Interconnection Hotline at (313) 235-4333 or email the Interconnection team and provide your name and address.
New residents are also required to sign a new Parallel Operating Agreement. If the previous homeowner installed the system under the Net Metering program, the system will continue under the program for the remainder of the 10-year period before transitioning to the Distributed Generation Program.
What if I move/sell my home after installing a private generation system?
Many homeowners who install solar panels or other renewable systems leave the system if they sell or change locations. The new owners assume responsibility for the system. If you acquire a home with a private generating system, as the new property owner, you must reapply to DTE to transfer the system into your name. You also have the option of removing your system and reinstalling it on another home, subject to eligibility requirements. You are responsible for these costs and will need to reapply (and meet all program requirements) to connect to the grid at your new location.
We know that installing a private generation system is a big commitment. While DTE won't design or install your system, we will work with you and your installer throughout the interconnection process.
This page outlines the four-step process you and your installer will follow to work with DTE to safely connect your system to the grid.
If you are not a registered installer with DTE, please call (800) 482-8720 and select option 4 to register. For additional information on the interconnection portal, see the Installer job aid. For residential customers, see the Residential Customer job aid.

The DTE Interconnection queue list can be found here. DTE will update this file no less than once per quarter.
Review your electric bills for monthly, seasonal and annual usage. Consider your plans for additional electric use as well as opportunities for energy efficiency. Know the amount of power your system will generate to meet your needs and budget. To access your usage data, sign in to your DTE account, click on Energy Usage Data, and follow the steps to download your Energy Usage Report.
Assess your home's potential, and be aware of common solar installation issues.
Meet with multiple installers. Determining your project's size is important, and consulting with installers will help you understand the project's scope and costs. Get references, review licenses and certifications and make sure you're confident your installer will keep you informed throughout the interconnection process. See tips for finding the right installer.
Projects are grouped into five categories. Most residential spaces will fall under Category 1 requirements. Please use the detailed table of project sizes and fees to find requirements for your project category. For Category 3-5 projects, please email us at email@example.com.
|Category & Requirements||Project Size||Application Fee|
|Up to 20 kW||$50|
|20 to 150 kW||$50|
|150 to 550 kW||$150|
|550 kW to 2 MW||$250|
Once your project size is determined, the engineering drawings are complete and all other required interconnection information is gathered, you or your installer (if you've agreed to your installer's proposal), will complete DTE's interconnection application in PowerClerk®. You will receive project updates via email, and your installer can access the PowerClerk website for status updates on the application.
After receiving your interconnection application and fee, DTE will review your project. Within 10 business days, DTE will notify you and your installer if your application is approved or needs to be amended.
We'll also inform you if you will need to choose a compatible electric rate. Learn more about the rate schedules to which the Rider 18 Distributed Generation program is attached.
Before installation begins, make sure your application is approved.
Some applications aren't approved during the technical review. If revisions are required, you or your installer will have 60 days to submit an updated application and correct the issues noted, or the application will be void.
There are project risks for not correcting technical deficiencies before installation:
Sunk costsNo application refunds.
DelaysProjects can be delayed for weeks or months.
ReapplyingThe application process, including fees and reviews, starts again.
Once your application is approved, you or your installer must upload required construction documents to PowerClerk and complete the installation within 180 days.
The sticker must specify that the final inspection was approved and the work description was for a solar energy system. It must also include the site address and be signed and dated by the local governing authority.
Photo must include the meter and A/C disconnect.
Please note: For safety reasons, this requirement protects you, DTE field technicians and emergency services.
The POA is a required contractual agreement between a customer and DTE explaining that both parties will operate their respective systems safely.
When a project is nearly complete, and before the site inspection, a POA will be emailed to the customer from DocuSign for an electronic signature. If necessary, DTE can also mail a hard copy of the agreement to the customer for a signature.
Please note: the POA must be signed by the customer and cannot be signed by an installer on behalf of the customer.
Once all construction documents are uploaded, DTE will review the documents for accuracy within 10 business days. If your construction documents are approved and your POA is signed and returned to the DTE interconnection team, your project will be scheduled for a site visit. If the construction documents are incomplete or need to be amended, the installer must resubmit these documents with corrections within 60 business days or you may need to reapply and pay an additional application fee.
On the day of the site visit, a DTE field technician will visit your location to test your private generation energy system. To prepare for the site visit, please ensure:
Solar panels are clear from debris (snow, leaves, etc.).
The inverter is on.
The AC disconnect switch is in the “OFF” position.
Reminder: The AC disconnect should not be switched to “ON” by anyone other than a DTE technician.
To ensure a safe connection, the AC disconnect switch will only be turned “ON” by a DTE technician after the site inspection and testing is successful.
DTE will email your signed POA through PowerClerk® for your records.
With all requirements complete and the system on, you can begin generating energy and outflow credits. Your DTE bill will reflect charges for your service as well as credits for your outflow. It may take one or two billing cycles for DTE to process your new bill.
To which rates can Rider 18 Distributed Generation be attached?
Rider 18 can be attached to any residential, commercial, secondary or primary rate schedules, except for the following:
D1-A RESIDENTIAL ADVANCED PRICING PILOT A
D1-B RESIDENTIAL ADVANCED PRICING PILOT B
D3.1 UNMETERED GENERAL SERVICE RATE
D9 OUTDOOR PROTECTIVE LIGHTING
Are there any other options for Category 1 and 2 or if I don't have a renewable generation source?
Yes, Rider 14 is available to qualifying customers with on-site generation capacity of up to 100 kW. Unlike Rider 18, the generation does not need to be renewable, and does not need to be limited to the rate schedule's on-site usage. However, the outflow credit on Rider 14 is based on the wholesale market, as opposed to the retail rate schedule. In addition, Rider 5 is available to Category 1 or 2 customers meeting the requirements as a Federal Energy Regulatory Commission Qualifying Facility.
Do I need to notify DTE if I'm planning to add a battery storage system?
DTE doesn't require customers to install battery storage. However, if you do wish to install a battery storage system, contact DTE to confirm the battery won't interact with the distribution system and to help ensure you maintain eligibility for service under the Rider 18 Distributed Generation Program or Net Metering. Export from batteries for Rider 18 connected systems is not permitted.
To submit a new application with the addition of a battery storage system, please Start Your Application.
Why isn't my battery storage or emergency generator permitted to discharge energy to the grid?
Since battery storage systems and emergency backup generators don't qualify as renewable energy resources, they aren't permitted to discharge energy back to the distribution system.
Businesses with a generator greater than 250 kW may qualify for the Dispersed Generation tariff (Rider 13) and receive voluntary dispersed generation payments for operating their generation at the request of DTE. For more information, call (800) 482-8720 and select option #4.
Learn more about eligibility for the Rider 18 Distributed Generation Program.
Solar installations connected to DTE's distribution grid are subject to DTE tariffs, Michigan Public Service Commission (MPSC) regulations and other laws. The regulations ensure that your system and the grid remain safe and reliable. Through DTE's process, from application through site review, we help to resolve potential issues with your system before you're connected.
Below are some timelines for key points in the process. It's important to be aware of these timelines to make sure the process continues to move forward. If a step is taking longer than expected, you can review your application or installation status in PowerClerk to identify and resolve issues as quickly as possible.
After your application is complete in PowerClerk® and payment has been received by DTE, we'll notify you within 10 business days if your application is approved for construction or needs to be amended.
Required construction documents must be uploaded to PowerClerk, and project installation must be completed within 180 days.
Testing & Inspection
A DTE field technician will visit your site and test your private generation system if installation is complete within the 180-day window.
Please note: When DTE is performing storm restoration, our engineering and field resources prioritize customer safety and restoration efforts. Interconnection review timelines and site visit timelines may experience delays until storm restoration is completed. Please visit the DTE Outage Center and view the Outage Map for up-to-date information.
Each renewable power generation system can connect to one meter. A private system can service an accessory unit, but must connect to the DTE distribution grid via a single meter.
Not every property can effectively accommodate solar power. Your roof pitch, shade and the angle of the sun are all factors.
Systems must be limited in size, not to exceed the customer's self-service needs of the rate schedule to which the Rider 18 Distributed Generation Program is attached.
Solar panels are a long-term commitment, so you will want to be sure your roof is in good condition before installation. Removing and reinstalling solar panels add unexpected costs to the project.
Local governments have strict rules about placement of cutoff switches and access lanes between panels so firefighters can effectively manage an emergency.
Your system will connect with both your building and the grid. Wires must be the correct gauges and connections must be properly made. In some cases, you may need to install a new primary service breaker.
All conductive materials in your solar panel system must be properly grounded. This process can be more complicated than a typical building's grounding bar. Remember, you're installing a small-scale power plant on your roof.
Please also review the Electric Service Installation Guide (Green Book, and also called the Service Installation Manual) and see Section 5 (Service Equipment) and Section 7 (Wiring and Appliance Installation).
Only the projects that you are the owner of will be displayed here. You can view all of your accessible projects in PowerClerk.
