Commercial operation date: the milestone that anchors an interconnection agreement
The date, fixed in the interconnection agreement, on which the generating facility is expected to begin commercial operation, and against which milestone obligations are measured.
The commercial operation date is the milestone in an interconnection agreement on which the generating facility is expected to enter commercial operation. It anchors the schedule for construction of interconnection facilities and network upgrades, and it is the reference point for the agreement''s milestone and default provisions.
Because the date is written into a jurisdictional agreement, moving it is a filing event. An amendment extending the date, or a suspension notice that adjusts it, is documented and becomes part of the docket record for that agreement.
The date is a contractual expectation, not a forecast this publication makes. Where a filing states a revised date, the item reports the date the filing states and cites the filing.
Questions
- Can the commercial operation date be moved?
- It can be amended, and suspension of construction adjusts it under the agreement's terms. Amendments are filed and appear on the docket.
- What happens if the date is missed?
- The agreement specifies the consequences, which can include default provisions, and the parties commonly resolve the situation through an amendment filed at FERC.
