Summer Demand Response Programs: A Hidden Profit Center

What Demand Response Programs Actually Do

Demand response programs pay businesses to reduce their electricity use during specific high-demand periods. These periods can occur on hot summer afternoons when the grid is under stress. Instead of the grid operator building more power plants to handle those rare peak hours, they pay large energy users to step back. Businesses who curtail their usage get compensated. The grid stays stable.

For large commercial energy users, this is not a conservation program. It is a revenue stream.

Why Summer Creates the Biggest Opportunity

Electricity demand peaks in summer. Air conditioning loads surge across entire regions simultaneously. When that happens, grid operators like PJM (the Pennsylvania-New Jersey-Maryland interconnection, which covers 13 states in the Mid-Atlantic and Midwest) face supply constraints that can drive wholesale electricity prices sharply higher.

Those same price spikes that hurt energy budgets are the exact moments demand response programs pay the most. Summer is when the financial rewards are typically the largest and when your ability to reduce load has the most value to the grid.

Capacity charges, what businesses pay for the right to draw power from the grid, separate from actual energy consumed, are also tied to peak demand periods. If your building draws high power during a handful of summer peak hours, it can set your capacity cost baseline for the following year. Reducing load during those hours can lower that baseline and cut costs that follow you for months.

Who Qualifies for Demand Response Programs

Most demand response programs target large commercial and industrial energy users, typically facilities with a peak demand above 100 kW.

Qualifying users often include:

• Large office buildings and commercial real estate portfolios
• Manufacturing and industrial facilities
• Cold storage and refrigeration-heavy operations
• Data centers and large technology facilities
• Hospitality and retail chains with significant HVAC loads

The key factor is the ability to reliably reduce load when called upon. If your building can shed a meaningful amount of electricity use for two to four hours on short notice, you likely qualify.

How to Enroll in a Demand Response Program

Enrollment typically happens through your energy supplier, a curtailment service provider (a company that aggregates demand reductions from multiple facilities and delivers them to the grid operator), or directly through your regional grid operator's program.

Here is how the process generally works:

1. Assess your load reduction potential. Before enrolling, you need to know how much load you can reliably shed. This means reviewing your interval data, energy usage measured in 15-minute increments, to understand which systems can be temporarily reduced without disrupting operations. HVAC setpoint adjustments, lighting reductions and pausing non-essential equipment are common strategies.

2. Choose a program type. Programs vary by commitment level. Some require you to respond within 10 minutes of a call event. Others give you 30 minutes or more. Higher response speed typically means higher payments. Know what your operations can realistically handle before committing.

3. Register with a curtailment service provider or directly with the grid operator. Most businesses work through a curtailment service provider who handles the administrative enrollment and ensures your load reduction counts toward grid requirements.

4. Complete a baseline measurement period. Grid operators need to establish your normal energy use before they can measure how much you reduce. This baseline period typically runs for a defined number of days prior to the demand response season.

5. Respond to event calls during the season. When the grid operator issues a demand response event, most common on hot weekday afternoons between June and September, you reduce load as committed. Your performance is measured against your baseline.

What the Financial Rewards Look Like

Payments vary by program, region and your committed capacity. Businesses that outperform their commitment may receive bonus payments. Those that underperform can face penalties, which is why accurate load assessment before enrollment matters.

Beyond direct program payments, the secondary benefit is the capacity cost reduction described earlier. Hitting a lower peak demand during the handful of hours that set your baseline can reduce capacity charges on your utility bill for the next 12 months.

Key Takeaway

Demand response programs for businesses pay large energy users to reduce electricity during peak summer hours when grid stress is highest and your curtailment has the most financial value. Enrollment starts with understanding your load reduction potential and choosing a program that fits your operational flexibility. The businesses that move before summer peak season are the ones that capture the full year of financial benefit.
