PJM’s new “first-ready, first-served” approach requires projects to demonstrate viability before entering the cycle study process, including up-front financial commitments and proof of site control. Based on historical performance, only a percentage of projects that apply for interconnection will sign interconnection agreements and become operational. Since 2020, PJM has processed more than 300 GW of projects, resulting in over 100 GW worth of projects with signed interconnection agreements. PJM Interconnection saw its queue become so backlogged that the regional transmission organization (RTO) effectively shut it down in 2022 to rework its processes. : This requires that PJM set clear rules for co-located load and generation, including the creation of three new transmission service options and new rules for behind-the-meter generation (BTMG).
