What happened
ERCOT's rulemaking record shows NOGRR 282, posted Nov 14, 2025 as urgent, establishes frequency and voltage ride-through requirements for Large Computational Loads. ROS tabled it in December 2025, then recommended approval in April 2026; TAC and the ERCOT board followed; the PUCT approved it July 9, 2026, effective Aug 1, 2026. Comments came from the Data Center Coalition, TIEC, Texas Blockchain Council, Tesla, Google and others.
Why it matters
High for Texas state and university AI infrastructure; the clearest adopted state-level rule the OCP specification aligns with.
Evidence and measured results
Primary regulatory record (status, votes, key documents); technical text in linked documents not reviewed line by line.
Limitations and uncertainty
Why now: the Oct 12 OCP specification says it closely mirrors NOGRR 282, making this the binding comparison point. Rule posted in 2025; detailed requirements are in linked documents.
Put this evidence to work
Lighthouse Advisory interpretation, grounded in this source. Enriched 2026-10-13; this does not change the original publication date. Each role follows the same checklist so takeaways compare across sources.
Sales
Role takeaway
- Customer problem
- Texas public entities and utilities siting AI data centers must meet a now-effective grid operator rule on load ride-through.
- Stakeholders
- State public utility commission staff
- Grid operator / ISO planning staff
- Transmission and distribution utilities
- State economic development office
- Universities and agencies hosting or buying AI compute
- Discovery questions
- Which large-load ride-through rule applies at this site today, and which is pending?
- Does the facility qualify for any legacy or grandfathering exemption?
- How will cooling and auxiliary loads behave during a voltage sag?
- Value hypothesis
- Interpretation: aligning AI data center designs with published ride-through requirements early can reduce interconnection rework; it cannot guarantee faster approval or grid stability.
- Potential engagement
- Bounded compliance-readiness check for a Texas AI computing site against NOGRR 282 and pending modeling rules.
- Unsupported claims
- That compliance is simple or low-cost
- Any NVIDIA-specific compliance status
- That the legal authority question is settled
Pre-sales engineering
Role takeaway
- Fit
- High for Texas sites of 75 MW or more; reference value elsewhere.
- Architecture and integration
- Rules apply at the service delivery point or point of interconnection bus, not at the rack.
- Prerequisites
- Large Computational Load registration
- Dynamic models per PGRR 144 (pending)
- Protection coordination
- Constraints
- Applies only within ERCOT
- Legacy exemption cutoff Nov 14, 2025
- Stricter voltage standards for agreements after Jan 1, 2028
- Security
- Not a security document; protection settings and monitoring telemetry shared with utilities need access controls reviewed separately.
- Proof of value
- Check the site against the approved NOGRR 282 text
- Document ride-through test or model evidence
Delivery
Role takeaway
- Work
- Confirm applicability and exemption status, then embed ride-through tests in commissioning plans.
- Dependencies
- ERCOT and TDSP interconnection process
- PGRR 144 modeling rules
- Ownership
- Facility owner with its transmission and distribution service provider; ERCOT oversight.
- Skills and adoption
- Facility engineers and public-sector owners need power-system study skills (dynamic models, protection coordination) that AI program teams usually lack.
- Governance checkpoints
- Exemption status confirmed in writing
- Root-cause and corrective-plan process ready
- Acceptance criteria
- Proposed: documented exemption or compliance evidence before energization
- Proposed: ride-through event reporting procedure in place
- Risks
- Disconnection orders for imminent reliability risk
- Litigation over ERCOT authority
- Rule changes from pending modeling requirements
Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Ride-through applies at the grid interconnection point.
Governance
Who approves, reviews and stays accountable for outcomes?
Adopted through ERCOT stakeholder process and PUCT approval.
Security and privacy
What data, permissions and controls need testing?
Not addressed.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Not addressed.
Procurement
What should contracts, pricing and exit terms secure?
Texas buyers of colocation should confirm provider compliance.
Operating model
Which teams own the service once it runs?
Ongoing reporting and corrective-action obligations.
