Advanced Demand Response Strategies for Small to Medium Illinois Businesses
Advanced Demand Response Strategies for Small to Medium Illinois Businesses
The Illinois electricity grid faces increasing stress from extreme weather, growing demand, and the complexities of integrating renewable energy. For commercial customers, this grid stress creates a remarkable opportunity: utilities and grid operators will pay your business to reduce electricity consumption during critical periods.
Demand response (DR) programs offer Illinois businesses a rare win-win proposition. Grid operators receive the flexibility they need to maintain reliability without building expensive peaking power plants. Businesses receive payments for providing that flexibility—often $5,000 to $50,000 or more annually for medium-sized commercial operations—while simultaneously reducing their own peak demand charges.
Yet despite these compelling economics, most Illinois small and medium businesses leave this revenue on the table. Some don't know DR programs exist. Others assume they're too small to participate. Many find program complexity overwhelming. This guide cuts through the confusion, providing actionable strategies for Illinois SMBs to capture DR revenue and reduce energy costs through advanced demand response participation.
Beyond the Basics: Is Your Illinois Business Missing Out on Hidden Demand Response Revenue?
The Demand Response Opportunity in Illinois
Illinois sits within two Regional Transmission Organizations (RTOs) that operate wholesale electricity markets: PJM Interconnection serves northern Illinois including Chicago, while the Midcontinent Independent System Operator (MISO) serves central and southern Illinois. Both RTOs operate demand response programs that compensate businesses for reducing consumption during grid emergencies and high-demand periods.
The scale of this opportunity is substantial. PJM's demand response programs collectively enrolled over 8,000 MW of curtailable load in recent auctions, with participants earning billions of dollars over the past decade. MISO operates similar programs serving its footprint. Beyond wholesale markets, ComEd and Ameren Illinois offer utility-specific programs that expand participation options for businesses of all sizes.
Why Most SMBs Miss Out
Despite lucrative opportunities, most Illinois small and medium businesses don't participate in demand response:
Awareness Gap: Many business owners and facility managers simply don't know these programs exist. Utilities and aggregators focus marketing on large industrial customers, leaving SMBs uninformed about opportunities scaled to their size.
Complexity Perception: Program rules, eligibility requirements, measurement protocols, and settlement procedures appear daunting to businesses without energy management expertise. The alphabet soup of acronyms (DR, PJM, MISO, CSP, PLC, EE) creates an intimidating knowledge barrier.
Size Assumptions: Business owners often assume demand response requires industrial-scale operations. In reality, aggregators combine smaller loads to meet market minimums, enabling businesses with as little as 25-50 kW of flexible load to participate.
Technology Concerns: Questions about required equipment, automation capabilities, and integration complexity discourage exploration. Modern DR programs have dramatically reduced technology barriers, with smart thermostats and simple controls enabling participation.
Operational Worries: Concerns about disruption during events—employee comfort, customer experience, production impacts—prevent many businesses from investigating whether participation could work for their specific situation.
The Hidden Revenue Calculation
Consider what a typical Illinois medium-sized business might earn from demand response:
Example: 50,000 Square Foot Office Building
- Total connected load: 250 kW
- Curtailable load (HVAC, lighting): 75 kW
- Annual capacity payment: $75/kW × 75 kW = $5,625
- Event payments (4 events × 4 hours average): $0.75/kWh × 75 kW × 16 hours = $900
- Total annual DR revenue: $6,525
Example: Medium Manufacturing Facility
- Total connected load: 800 kW
- Curtailable load: 300 kW
- Annual capacity payment: $75/kW × 300 kW = $22,500
- Event payments: $0.75/kWh × 300 kW × 16 hours = $3,600
- Total annual DR revenue: $26,100
These revenues come in addition to—not instead of—reductions in your own demand charges, which can add another 10-20% savings on total electricity costs. Most businesses achieving these results spend minimal time and effort once initial setup is complete.
Is Your Business a Candidate?
DR candidacy depends on having flexible loads that can be reduced without unacceptable operational impact. Strong candidates include:
- Office buildings with central HVAC systems
- Retail facilities with significant cooling loads
- Manufacturing facilities with non-critical process equipment
- Warehouses with refrigeration or climate control
- Hotels and hospitality facilities
- Healthcare facilities (non-critical areas)
- Educational facilities
- Multi-tenant commercial properties
Even businesses with limited flexibility often find 10-30% of their load can participate without meaningful operational impact. The key is identifying which loads are flexible and implementing appropriate control strategies.

Understanding the DR Program Landscape
Illinois businesses can access demand response through several channels, each with distinct characteristics:
PJM Capacity Market (Northern Illinois)
The PJM capacity market compensates resources—including demand response—for being available to reduce load during system emergencies. Key characteristics:
- Participation: Through Curtailment Service Providers (CSPs) who aggregate customer loads
- Commitment: Typically June-September obligation period
- Compensation: Capacity payments based on PJM auction clearing prices, currently $50-150/MW-day
- Events: Called during grid emergencies, typically 5-15 events per summer
- Duration: Events typically 4-6 hours
- Minimum load: CSPs generally require 100+ kW, though some accept smaller loads
MISO Demand Response (Central/Southern Illinois)
MISO operates Load Modifying Resources (LMR) programs with similar structure:
- Participation: Through aggregators serving MISO territory
- Compensation: Based on MISO capacity auction results
- Events: Called during emergency conditions
- Requirements: Vary by resource type and aggregator
ComEd Peak Time Savings
ComEd offers a simpler, utility-administered program available to smaller customers:
- Eligibility: Commercial customers on qualifying rate schedules
- Mechanism: Bill credits for reducing usage during peak events
- Notification: Day-ahead notification of event periods
- Flexibility: No commitment or penalty for non-participation
- Best for: Customers seeking entry-level DR experience
Aggregator Programs
Third-party aggregators offer turnkey DR participation for Illinois businesses:
- Services: Handle enrollment, measurement, settlements, and performance compliance
- Compensation: Share of DR revenues (typically 60-80% passes through to customer)
- Value: Simplify participation and assume performance risk
- Selection: Important to compare aggregator terms and services
Program Comparison for Illinois SMBs
| Program Type | Minimum Load | Commitment Level | Compensation | Complexity | Best For |
|---|---|---|---|---|---|
| PJM Capacity (via aggregator) | 50-100 kW | Firm seasonal | High ($50-150/kW-year) | Medium | Reliable, larger loads |
| MISO LMR | 100+ kW | Firm seasonal | Medium-High | Medium | Downstate facilities |
| ComEd Peak Time Savings | No minimum | None (voluntary) | Low-Medium | Low | DR beginners |
| Third-party aggregator | 25-100 kW | Varies | Medium-High | Low | Hands-off participation |
Maximizing Revenue: Advanced Strategies
Beyond basic participation, advanced strategies can multiply DR value:
Layered Participation
Sophisticated businesses participate in multiple programs simultaneously:
- Base layer: Capacity program commitment for reliable curtailable load
- Middle layer: Economic DR for voluntary curtailment during high-price hours
- Top layer: Emergency backup load reduction for grid emergencies
This layered approach can increase total DR revenue by 30-50% compared to single-program participation.
Peak Load Contribution (PLC) Management
In PJM territory, your capacity charges are based on your Peak Load Contribution—consumption during the 5 highest system demand hours. Strategic load reduction during these hours reduces PLC and thus capacity charges for the following year. The savings compound: lower PLC reduces both capacity charges AND increases DR value (more load available for curtailment).
Learn more about PLC management in our guide on capacity tag forecasting methods.
Coincident Peak Avoidance
Similar to PLC management, reducing consumption during transmission and distribution system peaks reduces cost allocations for network charges. Some Illinois businesses achieve $10,000-50,000+ annual savings through strategic coincident peak avoidance, in addition to DR revenues.
For detailed strategies, see our resource on coincident peak alerts and setting up a playbook.
Demand Charge Stacking
DR events often coincide with periods when your facility would otherwise set monthly peak demand. Successfully curtailing during these periods reduces both demand charges AND earns DR payments—double benefit from a single action.
Selecting the Right Aggregator
For most Illinois SMBs, working with an aggregator simplifies DR participation. Key selection criteria:
Revenue Share: What percentage of DR revenues pass through to your business? Industry standard is 60-80% to customer, 20-40% retained by aggregator.
Performance Guarantees: Does the aggregator assume performance risk, or are penalties passed through to customers?
Technology Requirements: What equipment does the aggregator provide or require? Are installation costs covered?
Contract Terms: How long is the commitment? What are exit terms?
Reporting: How transparent is the aggregator about event performance and revenue calculations?
Track Record: How long has the aggregator operated in Illinois markets? What do references say?
Your Step-by-Step Guide to Automating Energy Savings with Smart DR Technology
The Case for Automation
Manual demand response—having staff reduce loads when events are called—works but has significant limitations:
- Reliability: Human response is inconsistent, especially during nights/weekends
- Speed: Manual curtailment takes 15-30 minutes to implement fully
- Depth: Staff may not know which loads can be safely reduced
- Documentation: Manual efforts are difficult to verify for compliance
- Sustainability: Staff attention to DR degrades over time
Automated DR solves these problems. When an event signal arrives, preprogrammed sequences execute immediately and reliably. Automation typically improves curtailment depth by 30-50% while reducing operational burden to near zero.
Automation Technology Options
Option 1: Smart Thermostats Cost: $200-500 per zone Best for: Small commercial, distributed retail
Smart thermostats (Honeywell, Ecobee, Carrier) can receive DR signals and automatically adjust setpoints during events. Many aggregators provide complimentary smart thermostats to customers enrolling in their programs.
Implementation:
- Replace existing thermostats with DR-compatible models
- Connect to aggregator platform via WiFi
- Configure DR response parameters (e.g., raise cooling setpoint 4°F during events)
- System automatically responds when events are called
Option 2: Building Automation System (BAS) Integration Cost: $2,000-15,000 depending on existing infrastructure Best for: Larger facilities with existing BAS
Modern building automation systems can receive OpenADR signals and execute complex curtailment sequences across multiple systems (HVAC, lighting, equipment).
Implementation:
- Verify BAS OpenADR compatibility or add gateway device
- Develop curtailment sequences in BAS programming
- Test sequences to verify expected load reduction
- Connect to aggregator platform for signal delivery
- Refine sequences based on actual event performance
Option 3: Intelligent Load Controllers Cost: $500-2,000 per controlled load Best for: Specific high-value loads (EV chargers, water heaters, etc.)
Dedicated load controllers provide precise control over specific equipment without requiring full building automation.
Implementation:
- Install controllers on target loads
- Configure reduction sequences (off, reduced power, cycling)
- Connect to DR platform
- Set restoration parameters
Option 4: Turnkey Aggregator Solutions Cost: Often $0 upfront (aggregator-provided) Best for: Businesses wanting minimal involvement
Many aggregators provide complete automation packages—equipment, installation, and ongoing monitoring—at no upfront cost, recovering their investment through revenue share arrangements.
Automation Design Best Practices
Pre-Event Conditioning
The most effective DR automation anticipates events rather than just reacting. Common strategies:
- Pre-cooling: Lower building temperature 2-4°F before predicted events, then coast through the event period
- Pre-heating water: Raise water heater setpoints before events to store thermal energy
- Battery pre-charging: Ensure on-site storage is fully charged before events
- Production rescheduling: Shift energy-intensive operations to non-event hours when forecasts suggest events are likely
Comfort Protection
Automation should protect occupant comfort within acceptable bounds:
- Temperature limits: Never exceed defined setpoint limits regardless of event signals
- CO2 monitoring: Maintain ventilation minimums even during events
- Override capability: Allow occupants to override curtailment if needed
- Zone prioritization: Protect critical zones while curtailing non-critical areas more aggressively
Event Duration Management
Long events (4-6 hours) require different strategies than short events:
- Rotating curtailment: Cycle loads on/off to maintain average reduction while limiting any single area's downtime
- Staged response: Start with least-impactful curtailments, escalating only if needed
- Thermal mass utilization: Buildings with good thermal mass can coast longer; lightweight structures need lighter curtailment to maintain comfort
Testing and Optimization
Before committing to DR programs, test your automation:
Simulated Events
- Run curtailment sequences during normal business hours
- Monitor load reduction achieved
- Assess occupant/operational impact
- Refine sequences based on results
Baseline Verification
- Understand your normal consumption patterns
- Verify that DR meters capture accurate data
- Confirm aggregator baseline calculations match your expectations
Performance Documentation
- Record actual load reduction during test events
- Compare to program requirements
- Calculate expected revenues based on demonstrated performance
Continuous Improvement
- Review actual event performance against expectations
- Identify underperforming loads for sequence refinement
- Expand curtailment scope as you gain confidence

Frequently Asked Questions
QHow much can Illinois small businesses earn from demand response programs?
Earnings vary based on load reduction capability and program participation. Typical ranges: 1) Small commercial (10-100 kW curtailable load): $500-5,000 annually through capacity payments plus event payments, 2) Medium commercial (100-500 kW): $5,000-25,000 annually, 3) Larger medium businesses (500+ kW): $25,000-100,000+ annually. Key factors affecting earnings include: size of curtailable load, reliability of curtailment performance, number of called events per year, and program structure (capacity vs. energy payments). Most Illinois DR programs guarantee capacity payments regardless of whether events are called.
QWhat are the minimum requirements to participate in Illinois commercial demand response?
Minimum requirements vary by program: 1) PJM capacity market programs (through aggregators): Typically 100 kW minimum curtailable load, though some aggregators accept smaller loads, 2) ComEd Peak Time Savings: Available to all commercial customers on eligible rate schedules, no minimum, 3) Utility emergency programs: Generally 100-500 kW minimum depending on specific program, 4) Third-party aggregator programs: Some accept loads as small as 25-50 kW when combined with other participants. Most SMBs participate through aggregators who combine multiple smaller loads to meet wholesale market minimums and handle all program administration.
QWhat happens if my Illinois business can't reduce load during a demand response event?
Consequences depend on program structure and performance history: 1) Capacity programs: Failure to perform results in reduced capacity payments and potential penalties. Repeated non-performance can lead to program dismissal or financial clawbacks, 2) Energy-only programs: No penalty for non-participation, but no earnings either, 3) Most aggregator programs: Aggregators bear performance risk and only pass through penalties for egregious non-performance, 4) Building automation allows consistent performance. Best practice: Enroll only loads you can reliably curtail, start conservatively, and expand participation as you gain experience. Most programs allow some non-performance events without significant penalty.
QHow does demand response automation work for Illinois businesses?
DR automation typically involves: 1) Signal reception - Building automation system or smart devices receive DR event signals via OpenADR protocol, internet connection, or aggregator platform, 2) Pre-programmed response - Systems execute predetermined curtailment strategies (HVAC setpoint adjustment, lighting reduction, equipment shutdown schedules), 3) Load monitoring - Real-time monitoring confirms curtailment achievement, 4) Event completion - Systems return to normal operation when event ends. Setup requires: compatible building automation system or smart thermostats/controls, internet connectivity, integration with DR aggregator platform. Most systems can be installed for $2,000-10,000 depending on building complexity, with costs often offset by first-year DR earnings.
QWhat loads are best for demand response participation in commercial buildings?
Best DR loads have three characteristics: significant demand, operational flexibility, and minimal business disruption. Top candidates include: 1) HVAC systems (40-60% of building load, can pre-cool/heat then coast during events), 2) Lighting (10-25% of load, can dim 20-50% with minimal occupant impact), 3) Electric water heaters (can pre-heat and coast for 2-4 hours), 4) Refrigeration (can pre-cool and coast for 1-2 hours with proper temperature monitoring), 5) Non-critical process equipment (can schedule around events), 6) EV charging (highly flexible if not time-critical). Poor candidates: critical process equipment, life safety systems, elevator/escalator systems, and computing infrastructure without backup power.
