Cogeneration Distributed Generation

Cogeneration allows you to both purchase and sell power to and from Wright-Hennepin (WH). If you are planning to connect to WH’s grid and both buy and sell power, please follow these steps to facilitate a smooth process for your interconnection. This process needs to be completed prior to any cogeneration resource being interconnected.

(1) Electricity is generated through wind, solar, or another approved source of home generation; (2) An inverter transforms DC electricity to AC for home use; (3) Energy is consumed at the site; (4) A meter(s) records power used and power added to the grid; (5) Excess energy generated at home is fed into Wright-Hennepin's grid

Frequently Asked Questions

Pre-Application Request: (Not Required)

Persons interested in finding out the additional information regarding the interconnection of a distributed energy resource to Wright-Hennepin's distribution system are to fill out this Pre-Application Report Request. The Pre-Application Report Request is to be filled out as completely as possible by the applicant. Wright-Hennepin will provide the applicant with a Pre-Application Report within 15 business days once the completed Pre-Application Report Request and a $300 fee is submitted to Wright-Hennepin.

Simplified Interconnection under 20 KW:

Interconnections greater than 20 KW:

Note: Optional Interconnection Agreement may be used in lieu of the Uniform Contract for Cogeneration and Small Power Production Facilities.

If unsure, please contact our office by calling (763) 477-3150 or email us at newservices@whe.org.

  1. Work with your electrician or contractor and complete the Interconnection Application once you complete and finalize your cogeneration plans.
  2. Email or mail the appropriate applications and application fee with additional requirements to New Services at newservices@whe.org or mail to P.O. Box 330, Rockford, MN 55373.
  3. Upon receipt of the required documents, WH personnel will perform an engineering review of the proposed interconnection and determine the estimated construction charges that will apply. If changes are necessary, an email will be sent to the installer requesting additional information. If construction charges apply, an aid to construction agreement must be signed by the owner and submitted to WH New Services. Once approved, you will receive an email confirmation that the system has been approved and you may begin construction based on the final design.
  4. Notify WH when the system is ready to be interconnected along with the Certificate of Completion emailed to newservices@whe.org, mail to P.O. Box 330, Rockford, MN 55373 or fax to (763) 477-3052. A WH representative will contact you to make an appointment to perform the site test and interconnection.
  5. Complete the Cogeneration and small Power Production Facilities for installations 100 kW and below. For installations greater than 100 kW, WH will negotiate a contract consistent with WH’s Interconnection Agreement for the Interconnection of Extended Parallel Distributed Generation Systems with Wright-Hennepin Cooperative Electric Association.
  6. A grid access charge will be applied to applicable cogeneration systems. See Small Power Production Rider.

Frequently asked questions

  1. What do I need to do to connect with WH’s power grid?
    1. Follow the steps outlined above. If you have any questions, contact us at (763) 477-3000.
  2. Can I sell energy back to the utility if I generate more power than I use?
    1. Yes, you can. This is called net metering, excess production or rollover.
  3. How does Net Metering work?
    1. When a member’s system generates more power than is being consumed at the home, it sends the power back to WH. To easily monitor both the energy delivered to the home by WH and the energy delivered to the grid by the cogeneration facility, WH currently uses two meters (one for each). At the end of the month, systems less than 40 kW will “net” the total excess generation delivered to the grid from the total energy delivered to the home. See Small Power Production Rider for rate options.
  4. Are there any costs to me, to do so?
    1. WH will charge you for the cost of the interconnection and any service upgrade costs as well as an application fee. For more detailed information please email New Services at newservices@whe.org or call (763) 477-3150. You may also review our Small Power Production Rider for rate options.
  5. How much will you pay me for the excess power I produce?
    1. For systems less than 40 kW, WH will compensate the member for any net excess generation produced (energy produced above their consumption) at the “average retail utility energy rate.” For systems 40 kW and over, WH does not “net” the member’s excess production against their consumption. Rather, WH will purchase the total excess energy produced each month at its wholesale power supplier’s avoided cost.
    2. For a cogeneration system to qualify for the “average retail utility energy rate” through net metering, the following conditions must be met:
      1. Must satisfy the conditions established in Code of Federal Regulations, title 18, part 292. The size determination of the qualifying facility must include all facilities that are owned by the same person(s) or its affiliates, and are located at the same site. The “same site” means qualifying facilities that are located within one mile of each other.
      2. The aggregate of qualifying systems on a site must be less than 40 kW
  6. Can I still get power from WH when I need more than I produce?
    1. Yes, you can. WH has members participating in net metering, who both buy and sell power to the grid. We do not have any members totally off the grid. In Minnesota, there are long winter days with little sunlight. On these days especially, you will likely need power from WH.
  7. Interconnection Requirements: To ensure safe installations, all grid-tied cogeneration systems must meet relevant provisions of the National Electrical Code (NEC), the Institute of Electrical and Electronics Engineers (IEEE 1547) Minnesota Statute 216B.164, Minnesota Rules Chapter 7835 and electric utility requirements. Installations must also comply with all local permitting and zoning codes, fire codes, building codes and local and federal laws, rules, and requirements. The member installing Cogeneration is responsible for ensuring that the installer follows all applicable rules and codes, including WH’s interconnection process and requirements.
  8. Consumer protection – read before you buy
    1. We care about you. Please make sure when you are considering your own power generation, that you use a reputable company to do the work. We recommend getting three bids to make sure they are competitive. And make sure that you get referrals as well to protect yourself from a poor investment.

A member who has a dispute with the Cooperative with respect to the member’s or the Cooperative’s rights or obligations regarding distributed generation (such as wind generation or solar facilities) shall first complete the Dispute Form. The Cooperative will schedule an information meeting between you and the Cooperative’s CEO within 10 business days of receipt of this form. If that meeting does not resolve the dispute, then a hearing by the Cooperative’s Board or Directors will be scheduled. This process is governed by the Cooperative’s distributed generation rules as authorized by Minnesota Statues 216B.164, Subd. 11. Dispute Form
