Demand Response: Load Flexibility as Revenue
Demand Response programs pay C&I operators to curtail load when the grid is stressed. Whether it is worth collecting depends on your program options, your obligation tolerance, and your load profile.
Who this is for
- ■Plant managers and facility directors at manufacturers, hospitals, and data centers weighing DR enrollment
- ■Superintendents at K-12 schools and municipalities with controllable HVAC and lighting load
- ■Commercial real estate operators evaluating whether load flexibility is a genuine revenue line
- ■Finance and operations executives with electric bills in the five, six, or seven figures
Should our C&I operation enroll in a Demand Response program, and if so, which obligation level actually fits our operation?
A Demand Response program is a contractual arrangement where you agree to reduce electricity consumption when the utility or grid operator confirms the grid is under stress. In exchange, they pay you: either for the energy you shed during each event, for the capacity you commit to shed, or both.
One aggregator, Enel North America, reports delivering roughly 2 $B in DR payments across more than 10,000 sites C&I sites since 2011. That gives you a sense of scale. Per-site economics vary widely by program and by load profile.

- 02 The mechanism How an event actually unfolds
Using LADWP as a reference: the utility determines an event is needed based on peak demand and resource availability. You get notified by email or phone, either the day ahead or with two hours of notice. Then you execute your own curtailment plan. You control it. You define it. You plan it in advance.
Reference programLADWP program parameters
Parameter Value Maximum events per season 20 events Maximum events per day 1 event/day Maximum consecutive hours per event 4 hours Minimum curtailment threshold 100 kW Maximum opt-outs per season 2 opt-outs/season When an LADWP event can be calledEvents land in the afternoon and evening block. If your production or service load peaks in that window, that is exactly the capacity the utility wants to buy. Curtailment is not shutting down production. For most commercial buildings it is a coordinated adjustment of HVAC and lighting systems.
HVAC set points
Adjust global temperature set points and pre-cool the building envelope before the event window.Chillers and packages
Limit chiller demand; duty-cycle air-cooled package units on a pattern such as minutes on, minutes off.Static pressure
Reset static set point pressure controls to reduce fan and pump load.Lighting zones
Dim or curtail selected lighting zones without affecting critical areas.VFD reduction
Reduce variable fan speed on VSD and VFD systems for measurable kilowatt shed.Minimum threshold
You need to reliably shed at or above the program threshold to qualify for direct enrollment.Direct enrollmentLADWP pays two ways. First, an event incentive for the energy you actually shed. Second, a capacity incentive based on the curtailment level you committed to, with a higher rate for the shorter notice window because two-hour notice is harder for an operator to execute reliably than a day-ahead notice.

It reduces the equipment cost of participating reliably in a separate payment program.Your payment is calculated as the difference between what you would have consumed during the event and what you actually consumed. That reference figure is your baseline. If the baseline methodology sets your benchmark artificially low, say because your ten preceding days happened to be low-consumption days, you can perform perfectly and still receive a reduced payment.
How payment is measuredThe baseline is set before you ever curtail. If it is set wrong, no amount of good execution on event day fixes the math. A joint C4NET and RMIT-AGL research project found strong correlations between weather and historical demand for certain C&I segments like shopping centers, and used those correlations to build improved baseline models. The practical implication: if your baseline is not weather-adjusted, hot-day events can systematically under-measure your true reduction.
Assumption Reality If I curtail hard, I get paid for what I curtailed. You get paid for baseline minus actual. If baseline is understated, so is your payment. All baselines are basically the same. Simple day-average and weather-adjusted methods can produce materially different payments for the same event. The utility will pick the fairest method by default. Methodology is a program design choice. You need to know which one you are enrolled under before you sign. - 04 The trap The baseline is the hidden variable

Methodology is a program design choice. You need to know which one you are enrolled under before you sign. If your operation runs around the clock and you cannot reduce load without disrupting service, battery storage changes the participation math entirely. Instead of curtailing production, you discharge stored energy to meet your commitment. The facility keeps running. For hospitals, continuous-process manufacturers, and data centers, this is often the only viable path to enrollment.
JudgmentDaniel's take
- 1 Pull twelve months of interval data for the facility and identify the summer afternoon load you could reliably reduce.
- 2 Confirm your realistic minimum shed against the program threshold in your market. 100 kW
- 3 Count the opt-outs your production or service schedule would consume in a normal season and compare to the program cap. 2 opt-outs/season
- 4 Ask the aggregator or utility for the baseline methodology in writing, and whether it is weather-adjusted.
- 5 Evaluate whether storage or automation incentives change the participation math for your facility.

When DR enrollment is worth acting on
✓ Enroll and pursue- You can reliably shed at or above the program threshold from HVAC, lighting, and VFD systems in the afternoon window
- Your production or service schedule has enough flexibility to tolerate the program's opt-out cap in a normal season
- The program uses a weather-adjusted baseline, or you have negotiated one that fits your load type
- You have automation, storage, or aggregator support that removes the human-in-the-loop risk during events
- The capacity and event payments together justify the operational constraint on your load profile
✗ Do not enroll yet- You cannot hit the minimum curtailment threshold reliably without disrupting production or service
- The program is firm-commitment and your operation cannot guarantee reduction to a pre-set Firm Service Level
- The baseline methodology is not weather-adjusted and your load is climate-sensitive
- Opt-out tolerance in the program is tighter than the disruption your schedule will realistically create
- The only case you have seen for the numbers is a vendor deck, not a model built on your interval data
- Decision matrix

Questions for your morning huddle- What is the minimum load we can reliably shed, and does it meet the threshold for any programs available in our market?
- What is our realistic opt-out tolerance given our production or service schedule, and does the program we are evaluating stay inside that tolerance?
- What baseline methodology does this program use, and is it weather-adjusted?
- Do we have or could we deploy battery storage to participate without touching operations?
The one thing to rememberThe payment structure, the obligation level, and the baseline methodology all need to be evaluated against your actual operation before you commit. A generic vendor case study is not that evaluation.
Before your next vendor or utility call, pull twelve months of interval data, mark the summer afternoon window, and identify the kilowatts you could shed without touching production. Bring that number, and the four huddle questions, into the conversation.
Know if the numbers actually pencil out before you sign anything.
A written second opinion on the project in front of you, whether that is a rate change, new equipment, or a renewable installation.
- 01A short call, to figure out quickly whether we can actually be helpful. If we can't, we'll say so on the spot.
- 02We pull the data, your bills, your rate structure, vendor proposals, project specs.
- 03You get the verdict in writing: whether the payback will materialize, and the opportunities or risks nobody has raised.

- A contractual arrangement in which a C&I operator agrees to reduce or shift electricity consumption when the utility or grid operator signals grid stress, in exchange for payment.
- Event incentive
- A payment for each kilowatt-hour of energy actually shed during a DR event, measured against the baseline.
- Capacity incentive
- A monthly payment for the kilowatts of curtailment you commit to during the DR season, generally paid even in months when no event is called, subject to a minimum performance standard.
- Baseline
- The reference figure for what a facility would have consumed during an event window, computed from prior days. Payment equals baseline minus actual consumption.
- Weather-adjusted baseline
- A baseline methodology that corrects for temperature and other weather variables so a hot-day event does not systematically under-measure the true reduction.
- Firm Service Level (FSL)
- A pre-established load ceiling that a firm-commitment DR customer, such as a BIP participant, is required to drop to or below when a curtailment notice is issued.
- Aggregator
- An intermediary between utilities and C&I customers that manages program complexity, dispatch coordination, performance measurement, and payment administration for a portfolio of sites.
- Automated Demand Response (ADR)
- Automation that executes chosen energy controls on utility signal, reducing reliance on manual staff intervention during events. In PG&E's structure, ADR is a capital incentive that offsets the cost of installing that automation.
- Opt-out
- A participant's decision to sit out an individual DR event. Most programs cap the number of opt-outs per season, and firm-commitment structures effectively do not allow them.
