Risk, Reform, and What It Means for Data Centers
Recent developments between FERC and PJM have put behind-the-meter (BTM) generation and data center co-location squarely in the regulatory spotlight. The issue centers on how large loads – particularly AI-driven data centers – can connect directly with generation assets, and whether those arrangements are fairly allocating costs across the grid.
For developers and operators of mission-critical facilities, this is more than a policy debate. It is a structural shift in how onsite power will be treated going forward.
Below, we break down what is happening, what it means, and how to think about it strategically.
What’s Changing
FERC has directed PJM to clarify and update the rules governing data centers co-located with generation assets. Historically, certain behind-the-meter configurations allowed facilities to “net” their onsite generation against grid consumption, reducing exposure to transmission and capacity charges.
PJM’s proposed revisions would tighten those rules, particularly for large new loads. In practical terms:
- New large data center loads (e.g., >50 MW) may face more structured requirements.
- Some traditional “netting” benefits could be limited or eliminated.
- Onsite generation connected to the grid may no longer avoid certain system charges in the same way.
The objective from a regulatory standpoint is cost transparency and system reliability. The concern from some industry stakeholders is that removing historical tariff advantages could weaken the economics of certain behind-the-meter projects.
The Potential Downsides
From a developer’s perspective, the immediate challenges include:
- Economic Uncertainty
Projects that relied heavily on tariff optimization may need to be re-underwritten. If netting benefits are reduced, ROI models must adjust.
- Regulatory Transition Risk
Until final rules are adopted, there is potential ambiguity around how co-located generation will be treated in future interconnection or transmission filings.
- Short-Term Project Hesitation
Some stakeholders argue that if alternative mechanisms are not provided, distributed generation investment could slow in the near term.
In other words, regulatory clarity is still forming — and that creates friction.
The Upside
However, focusing only on lost tariff advantages misses the broader shift underway.
The energy landscape supporting AI data centers is evolving rapidly. Market volatility in PJM’s capacity auctions, increasing interconnection backlogs, and political scrutiny of large-load growth are changing how power is evaluated in site selection.
Behind-the-meter generation is no longer just a way to optimize utility charges. It is increasingly about:
- Securing faster energization in constrained markets
- Managing exposure to capacity pricing volatility
- Creating operational redundancy in extreme weather scenarios
- Providing optionality in uncertain regulatory environments
- Potentially participating in demand response or grid services
The FERC directive, while controversial in some circles, formally recognizes co-located generation as a structural element of grid planning. That legitimacy matters.
This is not the end of behind-the-meter strategy. It is the maturation of it.
The Bigger Shift: From Arbitrage to Infrastructure Strategy
The old model framed onsite power primarily as a financial workaround.
The emerging model positions onsite generation as core infrastructure – a hedge against grid delays, regulatory risk, and capacity volatility.
As AI workloads scale and jurisdictions diverge in market design, developers increasingly require engineered power systems that are compliant, grid-aware, scalable, flexible, and financeable
The economics are still compelling, but they are now driven by speed, resilience, and optionality rather than tariff loopholes.
What This Means for Data Center Developers
Jurisdictional differences in grid governance now directly influence development risk, long-term cost predictability, community acceptance, capital structuring, and overall project timelines.
In PJM, regulatory scrutiny and evolving rules require thoughtful structuring of co-located and onsite generation. In other markets like ERCOT, different frameworks create different risk profiles.
The common thread is clear – power strategy can no longer be treated as a secondary engineering decision. It is a foundational development variable.
