Path-Q Solar

Can physical installation begin before the utility approves the interconnection application?

Answer

Some physical work may be permitted before interconnection approval, but whether it is allowed and whether it is financially prudent depends on the utility, permitting authority, contract, and project design. The system should not be connected or operated contrary to utility requirements.

Key points

  • Permitting, interconnection, construction, inspection, and operation are separate approvals or milestones.
  • The utility may prohibit energization, meter changes, or certain connection work before approval.
  • Starting construction before the utility confirms the design can create rework if the connection method or equipment changes.
  • Get written confirmation of which activities may proceed and who bears the risk.

What it depends on

  • Utility interconnection rules
  • Local permit conditions
  • Approved design status
  • Contract payment and cancellation terms
  • Potential transformer or service upgrades

Risks and trade-offs

  • Early construction may save time if the design is stable but can create stranded costs.
  • A permit does not necessarily authorize grid connection or operation.
  • The customer may bear costs if utility approval changes the design.

Information you may need

  • Utility approval status
  • Permit status and conditions
  • Installer's proposed construction sequence
  • Contract allocation of redesign and delay costs

Your next step

What to do next

Ask the utility and permitting authority in writing which activities can proceed before approval, then make the contract conditional on interconnection acceptance.
