An "energy-only" shortcut could save PJM ratepayers $11B. (RMI)
The shortcut in question: Traditional interconnections require years of studies and "firm" capacity guarantees. But Energy Resource Interconnection Service (ERIS) lets plants plug in quickly (and relatively cheaply) by agreeing to be curtailed during grid congestion.
To unlock these savings, RMI argues PJM must move ERIS projects to a separate, faster track and manage overflows with real-time curtailment, à la ERCOT.
Bottom line: The "non-firm" resources ideal for ERIS often outperform incumbents amid grid stress (like PJM’s onshore wind fleet during Winter Storm Elliott). Properly accrediting these contributions could make the ERIS fast-track the new industry standard.
