​​​​​​​​​​​​​​​​​​​​​​​​​​​​​NRECA created the Distributed Generation (DG) Toolkit originally in 2014 to help electric cooperatives (co-ops) address various considerations raised by consumer-owned generation. Due to the rapid increase of installing DG units by co-ops consumer-members, the update of DER interconnection standard (i.e., IEEE 1547-2018), and the increase adoption of other technologies such as battery energy storage, the Transmission and Distribution Engineering Committee (TDEC) System Planning Subcommittee worked to update the DG Toolkit to include:​​

• ​More generic classification of DG sizes.
  
• Needed information of the new resources (e.g., battery energy storage).

• Relevant updated standards.
  

These materials provide models and guidance that each co-op can adapt to its unique needs with the consultation of their management, legal counsel and system engineers.​

The updated DG Toolkit includes the following documents:

Overview Documents:

• Guidelines for Electric Cooperatives ​

• Consumer-Member G​uidelines for electric power distributed generation installation and interconnection​​
  
  

Application Documents:

• For all sizes of DG installation:
  
• A model distribution cooperative agreement for interconnection and operation of distributed generation​ (which can be used as a template for all sizes with limited modifications)
• Small size applications:
  
• Small size DG model interconnection application
• Shortened small size DG application for residential members (only Solar and/or Storage)​
  

• Medium size applications:
  
• Medium size DG model interconnection application
  
• Large size applications:
• Large size DG model interconnection application
  
• Extra-Large applications:
• Extra Large DER fast-tack document​
  
  
• Extra Large – Generator Interconnection (GI) Study Data Sheets​​​​​
  
• GI datasheet – Synchronous
• GI datasheet – Photovoltaic
  

• GI datasheet – Wind​

• Small and Medium Size DG Testing and Commissioning Checklist
  

• Large and Extra Large Size DG Testing and Commissioning C​hecklist​​
