Are you interested in a distributed generation (DG) project greater than 50kW and less than 20MW?
Please access our resources below for more interconnection information and complete an online request for documents needed to apply for a DG Interconnection Agreement with your local electric cooperative and Hoosier Energy.
Frequently Asked Questions
Distributed generation (DG) projects refer to a variety of technologies that generate electricity and may include commercial and industrial application such as:
- Solar photovoltaic panels
- Combined heat and power systems
- Wind
- Hydropower
- Biomass combustion or cofiring
- Municipal solid waste incineration
- Fuel cells fired by natural gas or biomass
- Reciprocating combustion engines, including back-up generators
Yes. Any interconnection will require the Small Generator Interconnection Agreement (SGIA) to be signed by all parties which includes the Interconnection Customer, Member Cooperative, and Hoosier Energy.
No interconnection will be granted prior to executing the Small Generator Interconnection Agreement (SGIA).
The pre-application fee is $500.00.The interconnection Request Application tiered fee structure is as follows:
- Level 1: 51kW – 200kW $100 + $1/nameplate kVA
- Level 2: 201kW – 2000kW $500 + $1/nameplate kVA
- Level 3: 2001kW – 20MW $1000 + $2/nameplate kVA
The Interconnection Customer will be responsible for all transmission and distribution expenses related to their interconnection such as:
- System Impact and/or Facilities Studies, if required (estimated cost of studies would be proposed following Interconnection Request Application submission)
- Facility and/or infrastructure upgrades
Policy Requirements and Initial Steps
Generation interconnections greater than 50kW and less than 20MW:Generator interconnections to Hoosier Energy’s Member Cooperative distrubution system (< 69kV) will require coordination and study through Hoosier Energy. Interconnection Customers should submit an application and any required fees directly to Hoosier Energy.Generation interconnections at 20MW or above:Generator interconnections of 20MW or above are coordinated through the Midcontinent ISO (MISO) and must adhere to North American Electric Reliability Corporation (NERC) reliability standards. Interconnection Customers should proceed through the MISO process, at https://www.misoenergy.org/planning/generator-interconnection/.Generation interconnections at 69kV or above:Hoosier Energy’s 69kV lines are primarily transmission facilities that fall under MISO functional control or agency. Interconnections to MISO Appendix G (non-transferred facilities) and Appendix H (transferred facilities) are coordinated through MISO and must adhere to North American Electric Reliability Corporation (NERC) reliability standards. Hoosier Energy’s transferred facilities lists are available on MISO’s website.Interconnection Customers should proceed through the MISO process, at https://www.misoenergy.org/planning/generator-interconnection/
Distributed generation project interconnection inquiry for unknown interconnection location and project size: If an Interconnection Customer (Member-Consumer) inquires about a distributed generation project where the interconnection location and the project size are unknown, then the pre-application in the SGIP will be needed.Distributed generation project interconnection inquiry for known interconnection location and project size unknown: If an Interconnection Customer (Member-Consumer) inquires about a distributed generation project where the interconnection location and project size is known, the pre-application in the SGIP will not be needed, and the Interconnection Customer may begin the process with the Interconnection Request Application.If you need assistance in identifying which form you need to complete, please contact HoosierDG@hepn.com.
Glossary of Terms
-
- DER (Distributed Energy Resource): Any energy resource connected to the electric grid capable of injecting real or reactive power to the distribution or transmission system.
- Interconnection Customer: Any entity looking to interconnect distributed energy resources to Hoosier Energy or its member cooperative electric transmission or distribution system. If an IPP (independent power producer) asks for interconnection, they will need to become a member as their construction and station power will be served by the distribution Member Cooperative.
- Member Cooperative: One of Hoosier Energy’s 18 distribution Member Cooperatives.
- Hoosier Energy: Wholesale power provider for the Member Cooperatives and coordinator of the DG Interconnection Agreement process.
- SGIP (Small Generator Interconnection Procedures): Contains the procedures and the pre-application and Interconnection Request Application for a project greater than 50kW and less than 20MW.
- Pre-Application: Required when the project scope of an interconnection is unknown.
- Interconnection Request Form: Required form to determine eligibility for DG Interconnection approval or withdrawal, and if feasibility or other studies are required.
- SGIA (Small Generator Interconnection Agreement): Three-party agreement between the Interconnection Customer, Member Cooperative, and Hoosier Energy. The Interconnection Agreement is signed when a project is approved for interconnection.
- DG Purchase Agreement – Contract for Hoosier Energy to purchase excess energy (Note: not every project may decide to sell back excess electricity).
