Customer-Owned Renewable Generation in Wisconsin

Thank you for considering a renewable energy system for your home or business! To get the most out of your wind, solar or biogas system, it's important to maximize your energy-efficiency first.

It's also important to think about your location. Wind turbines need wide-open areas and consistently high wind speeds. Solar systems need unshaded southern exposure. WPS partners with Focus on Energy – a program that helps residents and businesses with cost-effective energy-efficiency and renewable energy projects. Focus on Energy offers many tools to help you:

If you're unsure about the renewable system that would be best for you, Focus on Energy offers Site Assessments.
When you're ready to talk to an experienced contractor, check out the lists of Full Service Installers from Focus on Energy. A good contractor will help you acquire permits, co-funding and an approved utility interconnection by filling out the paperwork for you.
WPS partners with Focus on Energy to offer various Cash-Back Incentives when you install a renewable energy system.

The process of adding a renewable energy system to your home or business and connecting it to the WPS electric distribution system is called "interconnection." The following information will guide you through the steps and requirements necessary to interconnect a renewable energy system with WPS. The interconnection process can seem overwhelming at first, but remember, a good contractor will help you get an approved utility interconnection by filling out the paperwork for you.

Parallel Generation Rates
- WPS Net Energy Billing
  - Net metering is a method of metering the electricity produced and used at a home or business that has an electricity generator, such as a small wind turbine or solar electric panels. With net metering, excess electricity produced by the generator is credited to the customer at the same price as if purchased from the utility, effectively banking the electricity until the customer needs it. This provides the customer with full retail value for all the electricity produced. See the official tariff for more details.
- WPS Parallel Generation Solar - Closed to new enrollments.
  - The parallel generation solar rate is for customers operating solar photovoltaic generation systems. Customers receive $.25/kWh for all electricity received from the generation facilities during each billing period.
Review and Understand the Rules and Requirements
Complete the Interconnection Application and mail to:
- If the application is for 20kW or less, complete the Standard Application Form.
- If the application is for 20kW to 100kW, complete the Distributed Application Form.

WPS Reviews the Application

WPS will review your application to determine if it contains all the information needed to begin the interconnection process. WPS will contact you about the status of your application. If the application is incomplete, additional information will be requested.
WPS Determines if a Distribution Study is Needed

After your application is considered complete, WPS will determine if a distribution study is needed. This study is to assess the level of impact your system will have when it's connected to the grid.

If the study is needed, WPS will inform you about the cost of the study. After you have provided written authorization to proceed and paid the applicable fee, we'll complete the study.
Discuss Distribution Study & Review Interconnection Options and Costs

Once the distribution study is complete, WPS will contact you to discuss all of the options available — along with their associated costs — and the timeline for the interconnection of your parallel generation system.
Install Parallel Generation and Distribution System Upgrades

You will need to install your generating equipment within a mutually agreed upon timeframe. After receipt of payment for the agreed-upon interconnection costs, WPS will perform all work needed to upgrade the distribution system to accommodate your parallel generation system.
Test the System

When the installation of your system is complete, notify WPS so we can witness or verify the system testing. This could include:
- Witnessing commissioning tests
- Performing anti-islanding tests
- Verifying the protective equipment settings
Sign the Interconnection Agreement

Before parallel operation can begin, both you and WPS will need to complete and sign a Standard Interconnection Agreement.
- Solar Buyback Interconnection Agreement
- If the application is for 20kW or less, complete the Net Energy Billing Interconnection Agreement
- If the application is for greater than 20kW and less than or equal to 100kW, complete the Distributed Generation Interconnection Agreement (20kW to 100kW).
