FERC Rejects RWE Complaint over PJM Interconnection Practices

Why It Matters

The rulings highlight growing pressure to bring certainty to interconnection costs while reshaping utility earnings and strengthening grid reliability and cyber resilience across U.S. markets.

Key Takeaways

• PJM interconnection costs jumped from $1.25M to $72M
• FERC urges reforms to reduce cost uncertainty for developers
• New England transmission ROE cut to 9.57%, limiting returns
• Utilities face $70M annual earnings hit from ROE reduction
• NERC updates cybersecurity standards for virtualization and low‑impact assets

Pulse Analysis

FERC’s rejection of RWE’s complaint underscores a systemic issue: developers often face unpredictable interconnection expenses that can derail projects before construction begins. PJM’s revised estimate for a modest 125‑MW solar‑battery venture illustrates how cost spikes erode investor confidence and delay needed clean‑energy capacity. By pointing to the Southwest Power Pool’s consolidated planning model, regulators signal a shift toward front‑loading cost assessments, a move that could streamline queue times and reduce speculative filings across regional markets.

The commission’s decision to lower New England’s transmission ROE to 9.57%—with a total cap of 12.09%—directly trims after‑tax earnings for utilities like Eversource by roughly $70 million annually. While the adjustment aims to protect ratepayers, utilities argue it contravenes statutory return‑on‑equity norms, potentially hampering capital formation for critical infrastructure upgrades. The backlash reflects a broader tension between affordable electricity and the need for robust investment pipelines in an era of aging assets and climate‑driven demand growth.

Beyond interconnection and ROE, FERC’s agenda tackled three additional fronts: cost‑share approval for Indiana utilities complying with DOE emergency orders, endorsement of NERC’s large‑load reliability standards for data centers, and a suite of cybersecurity updates that accommodate virtualization while safeguarding low‑impact assets. Together, these measures reinforce a holistic approach to grid resilience—balancing financial certainty, operational reliability, and cyber defense—positioning the U.S. power system to better absorb both market volatility and emerging threats.
