Manual vs. Automated Coincident Peak Management
Manual coincident peak management puts your facilities at risk of missing the window that determines your demand charges for the next year. Here's what automated CP management changes.
One of the few energy decisions your facilities make all year, coincident peak management, determines what you pay for the next 12 months based on a handful of hours.
Unlike electricity costs that accumulate gradually, CP exposure resolves quickly when grid demand is highest. For cold storage and industrial refrigeration operators running portfolios across multiple utility territories, that narrow window is exactly where manual processes break down.
This article breaks down how manual and automated approaches compare, why cold storage portfolios carry outsized exposure, and what coincident peak management software changes about outcomes.
What Is Coincident Peak Management?
Coincident peak management is the practice of monitoring, predicting, and reducing facility load when the grid approaches its maximum load capacity during peak hours for a billing period.
In markets governed by ISO/RTO (Independent System Operator/Regional Transmission Organization) structures like PJM Interconnection, your peak demand charges for the coming year aren’t set by average consumption. They’re set by your interval load during the handful of hours when the grid itself peaks.
In a 4CP coincident peak program, four peak demand events per year set your demand rate tag for the next 12 months. Your interval load during those peak hours is the only data point that matters for rate-setting purposes. Miss one, and you carry inflated demand charges through the following year.
For large refrigeration facilities, those charges represent a meaningful share of total electricity costs, making CP programs one of the most impactful cost management tools available to industrial operators.
No one announces these events in advance. Predicting coincident peaks requires tracking weather forecasts and grid load forecasts simultaneously, then acting fast when conditions align.
Why Cold Storage Facilities Face Outsized CP Exposure
Cold storage facilities can’t simply shed loads during peak demand periods the way other industrial sites can. Refrigeration systems run continuously, and the physical constraints of cold chain operations set hard limits on curtailment aggressiveness.
Cold storage facilities are also among the largest energy users on the grid. During a heat event (the conditions most likely to produce a coincident peak event), refrigeration systems work harder, increasing energy consumption and total electricity costs precisely when grid stress is highest. That combination of high load and limited flexibility puts cold storage operators squarely in CP exposure territory.
For portfolios spanning multiple utility territories, the complexity multiplies. Different markets run different CP programs with different peak demand periods, different notification windows, and different rate structures. Commercial and industrial customers operating across regions have to track all of them simultaneously, often without centralized visibility into which sites are most exposed on any given day.
How Manual CP Management Works: Where It Breaks
The manual process is familiar to most energy managers:
- Monitor third-party forecasting services or utility alerts
- Identify high-risk days
- Notify site teams
- Coordinate load curtailment
- Document actions for measurement and verification (M&V)
In theory, it works. At portfolio scale, it stops working reliably.
The first failure point is speed. These events don’t wait for business hours. Many occur on summer afternoons or weekends, off peak hours for most operations teams, when staffing is thin. By the time an alert reaches the right people, the response window has narrowed.
The second failure point is coordination. Executing curtailment across multiple sites simultaneously requires communication across teams with different schedules and different control system access. The third is documentation: without a system generating an automatic audit trail, M&V becomes a reconstruction exercise after the fact.
When asked about the most common execution failures in manual CP mamnagement, Ivy Arkfeld, Industrial Refrigeration Engineer and CrossnoKaye SME says:
“The biggest issue I see is coordination. You can have someone actively watching the grid and calling for sheds, but that still has to move through a chain of communication before the site takes action. If the prediction changes, you’re back to re-communicating a new shutdown hour and restarting that whole process.
With that many humans in the loop, there are a lot of opportunities for delay or error. So the failure point usually isn’t just alert lag — it’s the coordination required to turn the alert into the right action at the right site, at the right time.”
Manual programs also depend on the energy manager being available at the right moment. That’s a single point of failure dressed up as a process.
The Hidden Cost of a Single Missed Coincident Peak Event
The cost of a missed CP event doesn’t show up as a line item. It shows up as inflated peak demand charges that compound through the following year at every billing cycle.
Nick Green, Senior Manager of Refrigeration and Engineering at Americold, described what effective CP response looks like in practice. During a major heat wave in the Northeast, Americold’s ability to respond through a unified platform delivered $500,000 to $600,000 in savings at a single facility in one month. That outcome required more than visibility. It required the ability to act on what the data showed across facilities, with governance in place.
For operators using the Energy AI App, load curtailment during a coincident peak event executes automatically within operator-defined safety and temperature compliance guardrails, with no manual intervention required.
That’s what peak demand management looks like when it works. The gap between that outcome and a missed event isn’t just one bill. It’s 12 months of elevated electricity costs compounding at every affected site.
Manual vs. Automated CP Management: A Side-by-Side Look
The differences aren’t abstract. They show up in specific failure modes that compound at portfolio scale.
Benefits of Automated CP Management
Automation doesn’t remove operators from the process. It removes the bottlenecks that cause missed peak events in the first place.
Automated CP management delivers three advantages manual programs can't match consistently:
- Consistent response time regardless of time of day or who is on shift
- Multi-site coordination without communication overhead; automated systems execute the curtailment strategies across every qualifying site simultaneously
- Complete audit trail for every event, making M&V faster and more defensible for utility incentive programs
Automation also creates a foundation for improving over time. Systems that accumulate load data and historical peak patterns refine response strategies as they accumulate signal. That compounding improvement isn’t possible with a manual process that restarts each season.
Facilities with on-site energy storage can extend curtailment capability. But this only provides CP protection when integrated with real-time peak demand signals; otherwise charging during those periods doesn’t automatically translate into peak avoidance.
"ATLAS doesn't wait for a peak event to happen — it pre-positions the facility to handle it safely. By reading weather forecasts, regional load signals, and real-time grid conditions, ATLAS pre-cools refrigerated spaces within wide temperature bands before a shutdown begins, then manages a controlled recovery after. Operators are never flying blind: when an event is imminent, texts, emails, and in-app alerts notify facility teams before action is taken, while a dashboard confirms the power reduction happened. And if something goes wrong — a compressor failure, an ammonia leak, temperatures edging out of range — operators can restart early, skip, or pause with a single click. ATLAS is designed to meet sites at their constraints, not demand compliance."

How US Foods Turned Demand Response Into a Hands-Off Process
Nick Weaver, Senior Regional Manager of Facilities at US Foods, described the shift:
“We used to send a person in for two or three hours to monitor it and manage the demand response. Now it goes straight through ATLAS, and so it’s completely hands-off.”
That outcome reflects what the ATLAS Enterprise Control Platform (ECP) makes possible for operators managing peak demand across large facility networks. ATLAS delivered corporate-wide visibility across US Foods sites, enabling blanket changes across facilities and removing the staffing dependency that manual demand response requires.
For portfolios tracking energy usage across dozens of sites, removing that staffing dependency is what makes consistent execution achievable.
Operators set the parameters. The AI handles the response. Execution no longer depends on someone being available at the right moment. That’s the only way to make CP management reliable across dozens of sites.
Building a Coincident Peak Strategy That Scales
A reliable CP program requires data infrastructure, governance, and organizational alignment, not just software.
On the data side: effective CP management starts with real-time energy usage monitoring connected to external signals, including weather forecasts, ISO/RTO grid signals, and utility rate structures. Without that foundation, even a well-designed response strategy is working with incomplete information.
On the governance side: automated CP management works within boundaries operators define. Permissioned control means teams set curtailment limits that protect temperature compliance before any automated response runs. For facilities that have on-site storage assets, integrating them into the same governed control layer ensures discharge happens at the right moment.
Scaling a coincident peak program across a portfolio is a change management initiative as much as a technology one. The operations that sustain substantial cost savings year over year are the ones that treat it as a portfolio-wide program with repeatable execution standards, not a series of site-level projects that restart each summer.

Frequently Asked Questions
Do coincident peak programs apply in all utility territories?
Coincident peak programs are common in ISO/RTO-governed markets like PJM, MISO, and SPP, but they aren’t universal. Operators expanding into new regions should confirm the specific CP program structure (4CP, 5CP, or otherwise) before assuming their existing curtailment strategy transfers.
Can a facility participate in demand response programs and also manage coincident peaks, or do the two conflict?
Demand response participation and coincident peak avoidance can coexist, but they sometimes pull in opposite directions: a DR dispatch might increase grid load at a moment when CP avoidance calls for curtailment. Automated systems that monitor both program signals in real time can resolve these conflicts without requiring operators to manually adjudicate each event.
How does on-site energy storage change CP exposure?
A battery energy storage system can reduce CP exposure by discharging stored energy during peak demand periods, flattening the facility’s grid draw during peak hours. The benefit depends on system sizing and integration with real-time grid signals. Without that integration, charging outside those windows doesn’t automatically produce peak avoidance.
