Peak Load Management
Reduce demand charges and optimize energy consumption during peak periods with strategic load management
Understanding Demand Charges
Demand charges can account for 30-70% of your commercial electricity bill
What Are Demand Charges?
Peak Demand Billing
Demand charges are based on your highest electricity usage during any 15-minute interval within a billing period. Unlike energy charges tied to total kilowatt-hours consumed, demand charges penalize peak usage no matter how brief the spike, so a single moment can drive up your monthly bill.
Why Utilities Charge for Demand
Utilities must maintain generation, transmission, and distribution infrastructure capable of meeting your facility's maximum power requirements, even when peak demand occurs only briefly each month. Demand charges help recover the cost of building and maintaining that capacity.
The Cost Impact
For many commercial and industrial facilities, demand charges represent 30-70% of the total electricity bill, and in some rate structures a single 15-minute peak sets your demand charge for the entire month. That makes peak load management one of the most effective strategies for reducing energy costs, often delivering savings of 20-30% on total electricity expenses.
Common Causes of Peak Demand
Simultaneous Equipment Operation
Multiple high-load systems running at once, such as HVAC, production machinery, or data center cooling all operating together during hot weather or production shifts.
Process Inefficiencies
Poorly coordinated production schedules, unoptimized batch processes, or poorly maintained equipment can create unnecessary demand spikes that drive up electricity costs.
Seasonal Factors
Extreme weather driving high cooling or heating loads, seasonal production increases, or holiday periods when facilities run at maximum capacity to meet demand.
Peak Load Management Strategies
Comprehensive approaches to reduce demand charges and optimize energy consumption
Load Shifting
Move energy-intensive operations to off-peak hours when demand charges are lower or non-existent. We analyze your operations and identify opportunities to reschedule production runs, batch processes, or maintenance to minimize peak demand while maintaining efficiency.
Learn more →Load Curtailment
Strategically reduce or temporarily shut down non-critical loads during peak demand periods. We implement automated systems that shed load when demand approaches critical thresholds, protecting your facility from costly demand spikes while keeping essential operations running.
Learn more →Energy Storage
Deploy battery energy storage to shave peak demand by storing electricity during off-peak hours and discharging during peak periods. Modern batteries respond in milliseconds to prevent demand spikes and can be optimized to maximize demand charge savings while providing backup power.
Learn more →On-Site Generation
Use combined heat and power (CHP) systems, backup generators, or solar plus storage to reduce grid dependence during peak periods. We design and optimize on-site generation strategies that reduce demand charges while improving power reliability and resilience.
Learn more →Real-Time Monitoring
Implement advanced metering that provides 15-minute interval data, predictive alerts, and automated response. Our monitoring solutions give you visibility into demand patterns and enable proactive management before costly spikes occur.
Learn more →Equipment Optimization
Optimize HVAC, lighting, and process equipment to reduce baseline demand and prevent simultaneous high-load operation. We analyze schedules, implement smart controls, and coordinate operations to flatten your demand profile and minimize peak charges.

A systematic approach to reducing your demand charges
Demand Analysis
We analyze 12-24 months of interval data to identify demand patterns, peak periods, and cost drivers. This reveals when and why peaks occur, quantifies the cost impact, and pinpoints the most cost-effective reduction opportunities for your facility.
Strategy Development
Based on your operational requirements and facility characteristics, we develop a customized peak load management strategy. This includes identifying which loads can be shifted or curtailed, evaluating technology solutions, and creating an implementation roadmap with projected savings and ROI.
System Implementation
We coordinate the installation of monitoring systems, controls, and any necessary equipment, configure automated systems, train your team, and establish protocols for manual intervention when needed, all with minimal disruption to your operations.
Ongoing Optimization
Peak load management requires continuous monitoring and adjustment. We provide ongoing support to refine strategies, respond to changing operational needs, and keep your systems delivering maximum savings. Regular reporting tracks performance and surfaces additional opportunities.

Factors Affecting Savings
Rate Structure
Facilities with high demand charge components (above $10/kW) see the greatest savings potential. Time-of-use demand charges in some rate structures create additional savings through strategic scheduling and load management.
Load Profile
Facilities with high load variability and distinct peak periods have more opportunities for demand reduction. Operations with flexible scheduling, batch processes, or equipment that can be curtailed without impacting production are ideal candidates.
Operational Flexibility
The ability to shift loads, curtail, or modify operating schedules directly impacts savings potential. 24/7 operations may require more sophisticated solutions like energy storage, while single-shift operations often have greater flexibility for simple load shifting.

Peak load management: common questions
What is peak load management?
Peak load management is the practice of avoiding consumption during the specific intervals that set demand, capacity and transmission charges. It is distinct from general efficiency because it targets a small number of intervals rather than total consumption — a facility can reduce its bill significantly through peak management while using exactly the same amount of energy overall.
What is a coincident peak?
A coincident peak is an interval when the whole grid is at its highest demand, and in many markets consumption during those intervals sets a facility's capacity or transmission charges for the following year. ERCOT uses four summer intervals; PJM zones typically use one. Because the charge applies for a full year, avoiding a handful of hours can be worth more than a year of rate negotiation.
How do you know when a peak is coming?
Grid operators publish load forecasts, and curtailment providers issue peak alerts based on them. Prediction is imperfect, so most programs curtail on more days than turn out to matter, and the economics still work because the cost of an unnecessary curtailment is small relative to the charge being avoided.
Is peak load management the same as demand response?
No. Demand response earns payment from the grid operator for curtailing during called events. Peak load management avoids charges by staying off the intervals that set your billing. They use much of the same operational capability, and for many facilities the avoided charge is worth more than the program payment.
Related to peak load management
The same curtailment capability usually pays twice — once as avoided charges, once as demand response revenue.
