Merchant Transmission

This page is retiring on January 31. Try out the New Services Queue page now.

PJM’s queue-based interconnection process offers developers the flexibility to explore their respective merchant transmission interconnection business opportunities. Each phase of the process establishes various milestone responsibilities for the developer, PJM and each Transmission Owner (TO) impacted by the interconnection request. From the developer’s perspective, the process is structured such that proceeding with each phase imposes increasing financial obligations. A developer has the right to withdraw at any point.
The interconnection process is discussed in detail in Manual 14 Series.
