FERC ordered its six regional grid operators to file generation-adequacy reports by 20 July, forcing them to show whether supply can keep pace with data-centre load growth.

Key takeaway

FERC's 20 July reports will show whether US grids can meet the load data centres keep adding.

The Federal Energy Regulatory Commission (FERC), the US regulator for interstate power markets, has ordered its six regional transmission organisations (RTOs) to file generation-adequacy reports by 20 July under docket RM26-4-000. ¹ The six, PJM, MISO, SPP, CAISO, ISO-NE and NYISO, run the grids that carry most US electricity; a generation-adequacy report is each operator's account of whether supply can meet forecast demand, data centres included.

The deadline follows FERC's decision on 18 June to issue Section 206 show-cause orders to the same six operators rather than write a binding large-load connection rule . That choice pushed any final standard to 2027, so the 20 July filings are the near-term measure of how each grid is coping while the rulemaking drags.

The reports will not by themselves connect or curtail a single campus. They set the evidentiary record FERC will lean on when it finally rules, and they arrive as RTO queues fill with gigawatts of data-centre demand that existing generation cannot yet serve.

Deep Analysis

In plain English

The US federal energy regulator, FERC, has told six of the country's biggest regional power grid operators, including the one covering Virginia and the Mid-Atlantic, to hand in reports on 20 July showing whether they will have enough electricity supply to meet demand, much of it from data centres. This is not a new rule itself, just the evidence-gathering stage. FERC chose this slower route in June rather than write a binding rule straight away, so any actual new requirement on how data centres connect to the grid is unlikely before 2027.

Deep Analysis

Root Causes

The 20 July deadline exists because FERC's own 18 June show-cause orders, issued to meet an end-June deadline it had set itself in April, asked PJM, MISO, SPP, CAISO, ISO-NE and NYISO to justify their large-load tariffs rather than propose a unified rule; adequacy reports are the first deliverable in that slower, evidence-gathering process, with show-cause responses not due until 17 August and public comment not closing until 16 September.

PJM already operates under the tightest version of this problem: it is the only one of the six that has twice used DOE's Section 202(c) emergency curtailment authority against backup-equipped data centres in 2026, so its adequacy report will land against a backdrop the other five RTOs do not share.

What could happen next?

Meaning
FERC's evidence-first approach confirms no binding national large-load connection standard will exist before 2027, leaving states to keep legislating individually in the meantime.

Source Landscape

This story draws on neutral-leaning sources

Consensus view: The National Association of Regulatory Utility Commissioners, whose member state commissions sit downstream of whatever FERC ultimately decides on large-load tariffs, has treated the six RTOs' adequacy filings as the evidentiary base the eventual RM26-4-000 rule will need, meaning the 20 July deadline is procedural groundwork rather than a decision point in itself.

Counter-view: The R Street Institute, a market-oriented think tank that has commented on FERC's large-load dockets through 2026, argues the show-cause approach FERC chose in June defers the actual cost-allocation question to 2027 at the earliest, leaving PJM, ERCOT and the other four RTOs to keep managing load growth under ad hoc emergency orders in the meantime.

Key tension: Whether six separate RTO adequacy reports, due the same day, produce a coherent national picture FERC can act on, or six incompatible pictures that push RM26-4-000 further into 2027.

Different Perspectives

Antel, Uruguay's state telecom

Antel will build a $70m AI data centre in Canelones, announced after an 11-12 August Council of Ministers meeting, with construction from Q1 2027 and roughly 250 direct jobs. Uruguay is putting a sovereign AI facility on the state balance sheet rather than courting a hyperscaler to build one.

Comtel

Comtel is building a Figline Valdarno data centre inside the H2-Era Green Valley complex, powered by an 84 MW solar plant and selling waste heat to on-site farming. Co-location with generation and a heat offtaker is the model regulators elsewhere are now writing into connection terms rather than negotiating case by case.

Greg Abbott, Texas Governor

Abbott directed PUCT and ERCOT on 3 August to audit every queued data centre's ownership, incentives and water use, saying projects that fail the state's survey should lose grid access. QTS's co-chief executives welcomed the review; Agriculture Commissioner Sid Miller called it too vague and wants a special legislative session instead.

Government of Gujarat

Gujarat notified a Data Centre Policy on 7 August offering capital, interest, tax and duty subsidies for projects sourcing at least 51% green power, targeting 7.5 GW against a 74 GW installed base. Where other jurisdictions priced or restricted grid access this month, Gujarat is paying developers to come instead.

Taiwan's Legislative Yuan Economics Committee

The committee gave preliminary approval on 5 August to a self-generation mandate for large power users, including data centres, with fines up to NT$750,000. It agreed the obligation in principle while leaving the megawatt threshold that defines its reach to later implementing regulation.

Australian Energy Market Commission

AEMC advised ministers on 5 August that data centres should surrender renewable certificates against actual consumption, prove new demand with new firm capacity, and register as market participants. The advice would turn passive customers into obligated participants inside the market's dispatch and settlement machinery, ahead of an access-standards determination due in late October.
