Path-Q Solar
How can planned utility rule changes affect the timing of a solar purchase?
Answer
A planned rule change can affect export compensation, interconnection eligibility, equipment requirements, incentive availability, or grandfathering. The purchase timing should be based on the rule's effective date and the event that preserves eligibility—such as application, approval, installation, or commissioning—not merely on signing a contract.
Key points
- Identify the announced effective date and any transition or grandfathering provisions.
- Confirm which project milestone must occur before the change and what evidence is required.
- Model the economics under both the current and future rules if timing is uncertain.
What it depends on
- Official rule text and effective date
- Grandfathering and transition criteria
- Utility application and approval timeline
- Construction, inspection, and commissioning schedule
Risks and trade-offs
- A project may miss protection if the required milestone is misunderstood.
- Rushing to meet a deadline can increase price, quality, or construction risk.
- A proposed change may be delayed, amended, or not adopted.
Information you may need
- Official utility or regulatory notice
- Written grandfathering criteria
- Project milestone schedule
- Provider and utility confirmation of expected processing time
