INTERCONNECTION PROCESS (State Jurisdictional) PJM Interconnection Application Attachment BB Application FERC Jurisdiction Determination Wholesale Market Participation Agreement (WMPA) EDC - Dedicated Service Line Request Dedicated Service Line Application Engineering Site Survey ing & Installation Site Survey EDC Work Order Creation & Scheduling Cost Considerations EDC - State Level Interconnection Level 1 or 3 Interconnection Application Eligible Size: Up to 10 kw Application Fee: $500 / Site Equivalent to $50 / kw or $50,000 / MW Non-FERC Jurisdictional Individual WMPA per Site ~ PJM Combined Feasibility/Impact Study ~ PJM Facilities Study ~ PJM Construction Services Agreement EDC Cost + Contractor Cost to Install Administrative Exercise w/ Study Completed Above
PJM AGGREGATION CONSIDERATIONS Project Overview # of Generators 20 Battery Storage Systems Generator Size per Site 5 kw Aggregated Size 100 kw (0.1 MW) (20 x 5 kw) PJM Classification Generation Resource Energy Only Interconnection Aggregation Attachment BB Application WMPA PJM Model Points 20 separate applications 20 separate agreements 1 single point as aggregate Market Registration & Telemetry Aggregation PJM Telemetry Requirements Frequency Regulation Market Energy Market Capacity Market 1 Fleet (0.1 MW) 1 Market Resource (0.1 MW) 1 Market Resource 1 Market Resource (single pricing node) N/A
FUTURE CONSIDERATIONS Interconnection Process Project Design & Market Rules to Accommodate Behind the Resources Aggregated PJM Interconnection Application for Small DERs Mixed FERC and Non-FERC Projects As Aggregations ing Requirement Coordination Between PJM and EDC to Avoid Duplicate ing Data Sharing Between PJM, EDC, and GEN Aggregation Consistent Aggregation Rules Across All Markets Mix of GEN, DR, DER? Adding / Removing Resources to Existing Aggregation
