System Offset Notes

For customer-owned distributed energy systems, allowable solar generation sizing is determined by compliance with either of these two requirements:

  • Proposed PV system generating capacity is less than 12 kW-DC, or
  • Intended renewable energy offset is less than 200% of the customer’s total annual electric use at the time of interconnection application.


Systems that are not owned by the customer will be limited to an intended renewable energy offset of less than 120%.
