Estimated Time to Restoration (ETR): How Utilities Can Get It Right Every Time

June 29, 2026
4 min read

ETR is not a customer service problem. It is a field data problem. Every inaccurate estimated time to restoration issued during a major outage event traces back to the same root cause: the utility did not have a verified picture of damage scope, crew location, and circuit status when it issued the estimate. What the customer received was not an ETR. It was a guess dressed up as one.  

After Hurricane Beryl, regulators in Texas stopped treating that distinction as a matter of good practice. They started treating it as a compliance failure.

What ETR Is and Why It Matters Beyond Customer Relations

Estimated Time to Restoration is the projected date and time by which a specific customer or circuit will have power restored following an outage. On the surface, it looks like a customer service metric. A figure to post on the outage tracker. A number to give callers. In practice, it is something considerably more significant.

ETR accuracy touches four separate areas of utility operations simultaneously: customer trust, regulatory compliance, storm cost recovery, and legal exposure. Get it right and it is invisible. But if you get it wrong, it becomes the organizing document for an investigation.

After major outages, regulators do not just examine how long restoration took. They examine what was communicated to customers and when. They examine whether those communications were grounded in actual field data or were generated by a model running on incomplete inputs. They examine whether ETR updates were issued as conditions changed. And they examine whether the utility had the operational systems in place to produce accurate ETR in the first place.

That last question is the one most utilities are unprepared to answer. Because producing accurate ETR requires real-time field data, and most utilities still collect damage information in ways that introduce hours of lag between what is happening on the ground and what the outage management system knows about it.

The core problem in plain terms: A damage assessor on the ground sees a downed transmission line feeding four distribution feeders. That information needs to reach OMS, get translated into affected customers and circuits, be matched against crew availability and travel time, and flow into a customer-facing ETR.  

In paper-based or radio-based field capture systems, that chain takes hours. In digital real-time systems, like the one that KYRO AI has, it takes just a few minutes. The ETR accuracy gap is mostly a data latency problem.

Utilities that publish ETR without all four of the following inputs are publishing estimates that will fail under any serious scrutiny, regulatory or otherwise.

Most utilities have the OMS. Many have the circuit prioritization logic. The gap that consistently produces ETR failures is the damage data input: how long it takes for verified field damage information to reach the systems that calculate restoration time. The connection between field data accuracy and operational outcomes is direct, and ETR is one of the clearest examples of it.

The CenterPoint/Beryl Case: What Poor ETR Communication Cost

Hurricane Beryl made landfall near Houston on July 8, 2024. It was a Category 1 storm at landfall, having weakened from a peak of Category 5 in the Caribbean. For most utilities, a Category 1 event is a manageable restoration scenario. What Beryl revealed at CenterPoint was not a Category 1 restoration problem. It was an operational readiness problem that had been building before the storm arrived.

  • May 2024

A major derecho knocks out CenterPoint's outage tracker. The system is not restored before Beryl strikes six weeks later.

  • July 8, 2024

Beryl makes landfall. Approximately 2 million CenterPoint customers lose power. With the outage tracker still offline, customers have no way to check ETR status or confirm whether their outage has been logged.

  • July 11–16, 2024

As restoration stretches into its second week, public and political pressure intensifies. The Texas PUC launches a formal investigation. The Texas Attorney General opens a separate probe. Governor Abbott threatens to reduce CenterPoint's service territory.

  • November 21, 2024

The PUC publishes its investigative report. It identifies ETR communication failures as a major focus, recommends a consumer right to speak with a human representative who can provide accurate restoration estimates, and flags the $25,000 annual penalty cap for legislative increase.

The CenterPoint case matters because it made explicit what regulators had been moving toward for years: ETR is not an aspiration. It is an operational obligation. CenterPoint repeatedly acknowledged the communication failures in its meetings with the PUC and with customers, pledging to do better. That pledge came after the fact. The time to build accurate ETR capability is before the storm, not during the investigation that follows it.

State Regulatory Standards on ETR: Texas PUC, New Jersey BPU, and Florida PSC Compared

Regulatory requirements around ETR vary significantly by state, but the post-Beryl trajectory points clearly toward increased specificity and enforcement across all major hurricane-exposure jurisdictions.

The common thread across all three states is that regulators no longer treat ETR as a customer satisfaction metric. They treat it as a service reliability obligation with enforcement teeth. And in all three states, the standard is not just that ETR be provided — it is that ETR be accurate and updated as field conditions change.  

That requirement is impossible to meet without real-time field data flowing into the OMS.

How Real-Time Field Data Capture Produces Accurate ETR

Here is what the ETR data chain looks like when field capture is real-time versus when it is not.

Without real-time field capture

A damage assessor surveys a three-mile stretch of downed wire and damaged poles. They record findings on paper or call them in via radio. Hours later, those findings are entered into OMS by a back-office operator who is simultaneously processing calls from six other assessors. The ETR that OMS generates is based on incomplete data, weighted toward the damage already logged rather than the total damage portfolio. Customers in the last 20% of affected circuits receive ETR estimates that are consistently too optimistic, because their damage has not reached the system yet.

With real-time field capture

The same assessor submits a digital damage form from a mobile device. GPS coordinates are embedded automatically. The damage type, asset identifier, and estimated repair time are captured in a structured format that feeds directly into OMS without a manual entry step. The ETR OMS produces reflects actual field conditions within minutes of assessment, not hours. As new assessments come in, the ETR updates. As crews complete repairs, their status updates in real time and the ETR for remaining customers adjusts accordingly.

This is the operational difference KYRO AI's real-time field capture creates. When every damage assessor and field crew is capturing structured data in real time through a mobile platform, the ETR your OMS generates is grounded in verified field conditions.  

When crew hours are tracked and visible from the first hours of an event, restoration progress is measurable rather than estimated. The ETR becomes a calculation, not a guess.

Building an ETR Communication Protocol That Holds Up in a Regulatory Audit

After Beryl, several state regulators began requesting ETR communication logs as part of post-event reporting. The question they ask is not just whether ETR was provided, but whether ETR was accurate, and whether it was updated when the field picture changed.  

A defensible ETR communication protocol needs to answer all three questions with documented evidence.

  1. Establish initial ETR within two hours of damage assessment beginning. Do not wait for a complete damage picture to issue a first ETR. Issue a range based on initial assessments and widen or narrow it as more data comes in. A documented, time-stamped initial estimate is more defensible than silence.  
  1. Update ETR at defined intervals, every six hours at minimum during major events. Texas PUC requires daily updates for outages over 24 hours. New Jersey BPU and Florida PSC have more frequent requirements. Build update cadence into the event protocol, not as an afterthought.  
  1. Document the data source behind each ETR with a timestamp. Regulators examining post-event communication records want to know what field data supported each ETR at the time it was issued. If the answer is "our model" or "the storm response manager's judgment," that is a problem in an audit. If the answer is a timestamped damage assessment record, it is not.  
  1. Issue proactive corrections when ETR changes materially. If field assessment reveals damage significantly worse than initial estimates, communicate a revised ETR before customers call. Reactive ETR corrections after complaints arrive look like concealment. Proactive corrections look like operational honesty.  
  1. Maintain a complete ETR communication log throughout the event. Every ETR issued, every update, and every supporting data source should be logged with timestamps. This record is what gets produced in a regulatory audit. Reconstruct it after the event and it will not survive scrutiny. Generate it in real time and it will.  

See how FEMA documentation requirements follow the same logic in our FEMA reimbursement guide for utilities.  

The common mistake that makes all five steps fail: Building the ETR communication protocol without first fixing the field data pipeline. A perfect communication protocol backed by incomplete or delayed field data still produces inaccurate ETR. The protocol and the data infrastructure have to be built together. Neither alone is sufficient.  

Accurate ETR starts with real-time field data — KYRO AI provides both

KYRO AI's field capture platform gives damage assessors structured mobile forms with GPS verification, feeds assessment data directly into OMS, and generates the timestamped documentation trail that backs up every ETR for your utility issues.  

From first assessment to final restoration record, the data chain is complete and defensible.

Frequently Asked Questions

What is Estimated Time to Restoration (ETR) for utilities?

ETR is the projected date and time by which power will be restored to a specific customer or circuit following an outage. Accurate ETR requires real-time damage data, crew capacity and location, circuit prioritization logic, and OMS integration. Without verified field data, ETR is an estimate in name only.

What does accurate ETR calculation require?

Four inputs working together in real time: verified damage scope and location from field crews, available crew capacity matched against the damage portfolio, circuit prioritization logic accounting for critical load, and OMS integration that translates field data into customer-facing time estimates. Remove any one of these and ETR accuracy degrades significantly.

What happened with CenterPoint and ETR during Hurricane Beryl?

Beryl struck Houston in July 2024 while CenterPoint's outage tracker remained offline after a May derecho. With roughly 2 million customers without power and no way to check ETR, customer outrage prompted a Texas PUC investigation, a Texas AG probe, and a November 2024 PUC report recommending legislative fixes to ETR communication requirements. The $25,000 annual penalty cap was flagged for increase.

How does real-time field data improve ETR accuracy?

ETR accuracy is fundamentally a field data latency problem. When damage assessors capture structured, GPS-verified data in real time via mobile platforms, that data reaches OMS within minutes rather than hours. The ETR OMS generates reflects actual field conditions, updates as crews complete work, and can be documented with timestamped evidence if regulators ask how it was calculated.

What are Texas PUC's ETR requirements for utilities?

Under TAC Title 16, Chapter 25, Texas utilities must include an estimated time of full restoration in initial outage notifications for significant interruptions. Outages lasting more than 24 hours require daily ETR updates. Within five working days of restoration, utilities must submit a summary report including cause, affected facilities, customer counts, and the full restoration timeline. Post-Beryl recommendations may expand these requirements legislatively.
