Capacity interconnection rights: what a project earns by studying to deliverability

Capacity interconnection rights are rights granted under certain regional tariffs that allow a generating facility to be counted toward resource adequacy obligations. They are earned by passing the deliverability analysis associated with the higher, network-style interconnection service, rather than by connecting alone.

The distinction is between the physical ability to inject energy and the recognised ability to be relied on at peak. A project may be interconnected and able to sell energy without holding rights that allow it to be counted as capacity, because the deliverability study tests whether its output can reach load under the conditions the tariff specifies.

Because the mechanics are regional, the definition that governs any particular project is the one in the transmission provider''s tariff. Retention on repowering, transfer on sale, and treatment when a project reduces its capacity are all tariff questions, and each is documented in filings on the record.
