Two Texas businesses each consumed 43,200 kilowatt-hours last month. One paid an effective all-in rate of 14.8¢/kWh. The other paid 9.0¢/kWh, a difference of roughly $2,500 for the month on the same 43,200 kWh of energy. Their contracted supply rates were similar. Their TDSP was the same. What separated them was a single metric almost none of their competitors' commercial energy content bothers to explain properly: their load factor.
This piece covers exactly what load factor means for Texas commercial electricity, how the formula works, why the same energy consumption can produce dramatically different effective costs, and how load factor influences both the regulated TDSP tariff rates and the competitive REP quotes you'll receive. It includes three fully worked examples showing 20%, 60%, and 80% load factor businesses, and it flags the specific Texas tariff mechanism that ties distribution charges directly to annual load factor for larger commercial accounts on the Oncor system.
What load factor actually is
Load factor is the ratio of your average electricity demand to your peak electricity demand over a specified period. Expressed as a percentage, it tells you how consistently a facility uses electricity.
The two equivalent ways to express the formula:
Load Factor = Average Demand (kW) ÷ Peak Demand (kW)
Or, since average demand is total energy consumed divided by the hours in the period:
Load Factor (%) = kWh ÷ (Peak kW × Hours in period) × 100
A 30-day monthly billing period is 720 hours. A full calendar year is 8,760 hours.
The intuition
If a business's average electricity demand were exactly equal to its peak demand, it would be using electricity at exactly the same rate every hour of every day. Its load factor would be 100%. In practice, no commercial facility runs at 100% load factor; every operation has variability, seasonal patterns, and off-hours downtime.
A high load factor means the facility uses electricity relatively steadily. A large data center running servers continuously might operate at 85% to 90%. A continuous-process manufacturing plant running three shifts might hit 70% to 80%.
A low load factor means the facility has sharp peaks separated by long periods of much lower usage. A restaurant that opens for lunch and dinner service can run at 30% to 40%. A house of worship or event venue that operates a few hours a week can run below 20%.
Why kW and kWh, together, tell a fuller story than kWh alone
Every commercial electricity bill records two independent quantities. Kilowatt-hours (kWh) measure total energy consumed over time. Kilowatts (kW) measure the peak rate at which that energy was drawn. A bill that shows the total kWh number without the peak kW number is describing volume without describing the shape of demand. Both matter for what the bill actually costs. For a deeper walkthrough of how peak kW gets converted into demand charges, see our guide on demand charges and peak kW billing for Texas businesses.
The load factor formula, worked
Consider a Texas business with the following month:
- Total consumption: 43,200 kWh
- Peak demand: 100 kW
- Billing period: 30 days (720 hours)
Step 1: Calculate average demand.
Average demand = 43,200 kWh ÷ 720 hours = 60 kW
Step 2: Calculate load factor.
Load factor = 60 kW ÷ 100 kW = 0.60 or 60%
Equivalently:
Load factor = 43,200 ÷ (100 × 720) = 43,200 ÷ 72,000 = 0.60 or 60%
Both approaches produce the same result. The two equations are algebraically identical; use whichever version is easier given the numbers you have on hand.
Which "peak kW" to use
For a generic educational load factor calculation, use the highest 15-minute demand recorded during the billing period. This is what appears on your commercial bill as the peak demand or NCP kW.
For calculations that will feed into an actual TDSP tariff (where certain rate schedules use load factor bands to set the distribution charge), the applicable "peak kW" is whatever your tariff defines as the billing determinant. For Oncor's Secondary Service Greater Than 10 kW schedule, for example, the annual load factor is calculated using the maximum non-coincident peak (NCP) kW recorded over the preceding 12 months, applied for the following 12 billing months. The applicable tariff document from your TDSP controls the specific calculation.
Do not confuse the following concepts, which get mixed together in a lot of published commercial energy content:
- Load factor measures average demand against peak demand over a period.
- Power factor measures real power (kW) against apparent power (kVA) at a given moment. This is an electrical engineering concept related to how efficiently your equipment converts current into useful work.
- Capacity factor is usually a generation metric, measuring how much a power plant produced against its theoretical maximum output.
- Utilization rate is a broader operational term used across industries; it doesn't map cleanly to the electricity load factor formula.
Load factor is about the shape of demand over time. Power factor is about the electrical characteristics of the load at any moment. A facility can have a high load factor (steady operation) and still have a bad power factor (poor motor control), or vice versa. They're independent measurements.
Three Texas businesses at 20%, 60%, and 80% load factor
To make the impact of load factor concrete, consider three Texas commercial buyers who each consume exactly the same 43,200 kWh in a 30-day month. What varies is their peak demand.
The illustrative rates below use:
- Contracted supply rate: 7.0¢/kWh
- REP base charge: $15/month
- Aggregate TDSP demand rate: approximately $11.27/kW (representative of Oncor Secondary Service Greater Than 10 kW as of April 30, 2026)
- TDSP volumetric and fixed charges included at approximately $50/month for the three examples
- Taxes and PUC assessment excluded for simplicity
Business A: Low load factor (event venue or house of worship)
- kWh: 43,200
- Peak kW: 300
- Average demand: 60 kW
- Load factor: 20%
This is a facility that operates intensely during specific windows (evening events, weekend services, occasional large gatherings) and sits nearly empty the rest of the time. HVAC systems, lighting, and equipment all fire up simultaneously during operational periods, producing a large peak. Between events, consumption drops to a trickle.
Simplified monthly cost:
- Energy supply: 43,200 × $0.07 = $3,024
- REP base: $15
- TDSP demand: 300 × $11.27 = $3,381
- TDSP other: ~$50
- Total: ~$6,470
Effective all-in rate: 6,470 ÷ 43,200 = 14.98¢/kWh
Business B: Medium load factor (typical office or retail store)
- kWh: 43,200
- Peak kW: 100
- Average demand: 60 kW
- Load factor: 60%
This is a business operating regular weekday hours with normal HVAC, lighting, computing, and appliance loads. Peak occurs during business hours, drops overnight, and rises again the next day. The pattern is repeatable and moderate.
Simplified monthly cost:
- Energy supply: 43,200 × $0.07 = $3,024
- REP base: $15
- TDSP demand: 100 × $11.27 = $1,127
- TDSP other: ~$50
- Total: ~$4,216
Effective all-in rate: 4,216 ÷ 43,200 = 9.76¢/kWh
Business C: High load factor (continuous manufacturing or cold storage)
- kWh: 43,200
- Peak kW: 75
- Average demand: 60 kW
- Load factor: 80%
This is a facility running near-continuously: 24-hour manufacturing, cold storage refrigeration cycling steadily, or a data center running server load around the clock. Peak demand is only modestly higher than average demand because the operation is designed for consistent output.
Simplified monthly cost:
- Energy supply: 43,200 × $0.07 = $3,024
- REP base: $15
- TDSP demand: 75 × $11.27 = $845
- TDSP other: ~$50
- Total: ~$3,934
Effective all-in rate: 3,934 ÷ 43,200 = 9.11¢/kWh
The comparison
Low LF (event venue): 300 kW peak demand, 20% load factor, approximately $6,470 total monthly, effective all-in rate 14.98¢/kWh.
Medium LF (office): 100 kW peak demand, 60% load factor, approximately $4,216 total monthly, effective all-in rate 9.76¢/kWh.
High LF (continuous operations): 75 kW peak demand, 80% load factor, approximately $3,934 total monthly, effective all-in rate 9.11¢/kWh.
All three businesses consumed the same 43,200 kWh at the same 7.0¢/kWh contracted supply rate. The effective all-in cost ranged from 9.11¢/kWh to 14.98¢/kWh. That's a 65% difference in effective per-kWh cost driven entirely by demand shape, not by energy consumption.
This is why "get me your cheapest ¢/kWh rate" is the wrong instruction to give a broker. The supply rate is only part of the picture. Two suppliers can quote you the same ¢/kWh and your actual bill will differ based on how your load shape interacts with the TDSP delivery structure. And that's before we consider whether the tariff itself uses load factor bands to set the demand rate.
Why load factor influences your electricity rate
There are two separate mechanisms, and content that discusses only one of them is telling half the story.
Mechanism 1: Regulated TDSP tariffs that use load factor bands
Some Texas TDSP tariffs directly incorporate load factor into the rate calculation. Oncor's current Secondary Service Greater Than 10 kW schedule, for accounts with NCP demand greater than 20 kW, tiers the distribution system charge by annual load factor:
- 0 to 10% annual load factor: distribution system charge approximately $9.83/kW
- 11 to 15% annual load factor: approximately $8.92/kW
- 16 to 20% annual load factor: approximately $8.59/kW
- 21 to 25% annual load factor: approximately $8.32/kW
- 26% and above annual load factor: approximately $6.93/kW
Figures are illustrative of the June 1, 2026 tariff schedule as documented in Oncor's tariff filing; current rates should be verified directly at oncor.com or through the PUCT rate information at puct.texas.gov.
The mechanism is straightforward: on this Oncor schedule, a customer with 100 kW billing demand pays a distribution system charge of approximately $9.83 × 100 = $983/month if their annual load factor is 5%, but only about $6.93 × 100 = $693/month if their annual load factor is 30% or higher. That's a $290/month difference in the distribution system charge alone, driven entirely by the customer's load factor category.
This is not a broker's pricing heuristic. It is the applicable Oncor tariff, approved by the PUCT and passed through by every REP. Improving your annual load factor on this schedule directly reduces your regulated delivery cost.
Not every TDSP or rate schedule uses annual load factor bands the same way. CenterPoint's tariff, TNMP's tariff, and AEP Texas Central and North each have their own structures. But the general point holds: for some Texas commercial rate schedules, load factor is a direct input to the tariff, not just an indirect pricing consideration. For the full breakdown of how each utility structures its commercial tariff, see our overview of TDSP delivery charges across Oncor, CenterPoint, AEP Texas, and TNMP.
Mechanism 2: Competitive REP pricing
The second mechanism operates in the competitive supply market rather than the regulated delivery tariff. When a Texas REP quotes a commercial supply contract, its pricing reflects the cost of hedging the customer's expected load pattern in the wholesale ERCOT market.
A customer with a high load factor (steady, predictable, weekday-focused consumption) is relatively cheap to serve. The REP can hedge that load with standard block products on the forward curve. Its supply cost is predictable, and its risk margin is low. Quotes for high-LF customers tend to come in tight against the ERCOT forward curve.
A customer with a low load factor (spiky, unpredictable, weekend-heavy, or event-driven consumption) is more expensive to serve. The REP must hedge more actively, may need to buy shaping products, and takes on more balancing risk against real-time market prices. Its supply cost is less predictable, and its risk margin has to be higher. Quotes for low-LF customers reflect that. The effect is not universal (some REPs specialize in certain load profiles and price them competitively), but on average, low-LF quotes carry a premium.
Neither mechanism is exclusive; both apply simultaneously to most commercial accounts. Improving your load factor lowers your regulated distribution cost (where applicable to your tariff) and improves the competitive supply quotes you can source.
How to calculate your load factor from your bill
You need three numbers, all of which appear on a demand-metered commercial bill or in your Smart Meter Texas data:
- Total kWh consumed during the billing period (from your bill).
- Peak demand in kW during the billing period (from your bill, typically labeled "peak kW" or "billing kW").
- Number of days in the billing period (from your bill).
The math:
Hours = Days × 24
Load Factor (%) = kWh ÷ (Peak kW × Hours) × 100
Example: A bill shows 62,500 kWh over 31 days with a peak demand of 175 kW.
- Hours = 31 × 24 = 744
- LF = 62,500 ÷ (175 × 744) × 100 = 62,500 ÷ 130,200 × 100 = 48.0%
For annual load factor, sum 12 months of kWh, use the highest 12-month peak kW, and use 8,760 hours (or the actual sum of hours across the 12 billing periods if you want precision):
Annual LF = Annual kWh ÷ (Peak kW × 8,760) × 100
For a walkthrough of pulling and interpreting the 15-minute interval data behind these numbers, see our Texas commercial electricity bill audit guide, which covers the Smart Meter Texas data pull and reconciliation process. If you don't know your ESI ID, our ESI ID lookup for Texas commercial addresses finds it from your service address.
What is a good commercial load factor?
There is no PUCT-established "good load factor" benchmark for Texas commercial accounts. What counts as a strong load factor depends on the type of business.
The following ranges are typical observed patterns across Texas commercial sectors. These are illustrative benchmarks, not standards. A facility outside these ranges is not necessarily doing anything wrong; the appropriate load factor depends on how the business operates.
- Continuous manufacturing (24/7 operations): typically 65 to 85%
- Data centers and hosting facilities: typically 75 to 90%
- Cold storage and refrigerated warehousing: typically 60 to 80%
- Hospitals and healthcare: typically 55 to 70%
- Grocery and supermarkets: typically 55 to 70%
- Hotels and multifamily properties: typically 45 to 60%
- Warehouses (day-shift operations): typically 40 to 55%
- Offices: typically 30 to 45%
- Retail (weekday-focused): typically 30 to 45%
- Restaurants and food service: typically 25 to 45%
- Schools and educational: typically 25 to 40%
- Houses of worship, event venues: typically 15 to 30%
Two observations:
A restaurant operating at 32% is not inefficient. It's operating consistently with the nature of restaurant load: intense meal-period peaks separated by shoulder-hour valleys. The way to improve the effective electricity cost of a restaurant is to reduce specific peaks (staggered kitchen equipment startup, HVAC pre-cooling before dinner service) rather than trying to raise the load factor to some abstract target.
A data center operating at 90% is not automatically excellent. It might simply reflect that cooling equipment must match server load one-for-one. The way to improve a high-LF data center's cost isn't to raise load factor further; it's to negotiate a supply contract that properly prices the flat load and to consider battery peak-shaving during 4CP intervals.
Load factor tells you the shape of your demand. Whether that shape is appropriate is a judgment about your operations, not something a load factor number alone answers.
How to improve your commercial load factor
Improving load factor means reducing your peak kW relative to your average kW. There are two ways to accomplish that: reduce the peak, or raise the average (or both).
Reduce peak demand
Stagger equipment startups
The single highest-return intervention for most facilities. If your operation currently turns on HVAC, refrigeration, compressors, and production equipment at the same clock time, stagger these across 15 to 30 minutes. Peak demand can drop 15% to 25% with no operational impact.
Shift flexible loads to off-peak hours
EV charging, battery charging for material handling equipment, water heating, and some process loads can often be moved to overnight or weekend operation. Any load moved out of your peak window reduces peak kW without reducing consumption.
HVAC pre-cooling and setpoint management
Pre-cool buildings early in the morning when outside temperatures are lower, then raise setpoints slightly during your peak demand window. Compressor draw during peak intervals falls without measurable comfort impact.
Install demand controls
Automated systems that monitor real-time load and shed non-critical equipment when demand approaches a threshold can flatten peaks reliably. Payback for demand control systems is typically 12 to 24 months for facilities with peaks above 200 kW.
Battery peak shaving
Commercial battery storage discharges during your peak window and recharges during off-peak hours, reducing the peak your meter sees. Battery economics improved substantially through 2024 to 2026, and for facilities with high predictable peaks, payback is now 4 to 6 years in many cases.
Raise average demand (only if productive)
The other side of the equation: if you can add profitable base load that runs continuously without adding to your peak, your average demand rises while your peak stays the same, and load factor improves.
This is not "use more electricity to get a better rate." That would be counterproductive. It's more useful in specific situations:
- A manufacturer considering adding a second or third shift where the production is profitable independently and the additional overnight load fills valley hours.
- A facility considering electrification of process heat, refrigeration, or transportation loads where the additional consumption has independent operational or cost justification.
- A cold storage operator adjusting cycling patterns to smooth the overall load rather than reduce it.
Do not add load that isn't independently justified just to improve load factor. The math almost never works.
Load factor in the procurement process
If you're preparing to shop your Texas commercial electricity contract, load factor is one of the metrics competitive REPs will care about. Providing them with clean load factor data (and preferably 12 months of interval data) improves the quality of quotes you'll receive.
Before you request quotes
Pull the following:
- 12 months of billing history showing monthly kWh and peak kW
- Your calculated monthly load factor for each of the 12 months
- Your calculated annual load factor
- Your 15-minute interval data for at least the highest-usage months, from Smart Meter Texas
- Your ESI ID and TDSP information
REPs pricing a commercial supply contract will run this data through their pricing models to produce a quote. Well-prepared load data typically produces tighter quotes than a REP would offer working from generic assumptions about your load shape.
What a good procurement RFP does with load factor
A structured commercial procurement process feeds identical load data to every REP being asked to quote. This ensures apples-to-apples comparisons. Common mistakes to avoid:
- Letting each REP see different versions of your data
- Providing kWh totals without peak kW information
- Requesting quotes without specifying the term, product, or start month
- Comparing quotes on headline ¢/kWh without accounting for how each supplier priced the specific load shape
Electric Decisions runs supplier-neutral RFPs that provide identical, complete load data to every bidder and benchmark the resulting quotes against the live ERCOT forward curve. The 5-step process is documented at our Texas commercial electricity procurement guide.
Monthly vs. annual load factor
These serve different purposes:
Monthly load factor tells you how consistently a facility operated during a specific billing period. It's useful for spotting month-over-month changes: if load factor drops sharply in a specific month, something changed (operational shift, equipment failure, seasonal pattern).
Annual load factor is a more stable measure of the facility's underlying demand shape. It smooths out seasonal variability and is the figure some TDSP tariffs use to set rate schedules (like the Oncor example above).
For a facility being shopped for a new supply contract, both are useful. Annual load factor tells the REP the general shape of the load. Monthly variation tells the REP how much the shape moves around during the year (which affects hedging cost).
For seasonal businesses (event venues, agricultural operations, schools on 9-month schedules), monthly and annual load factor can differ substantially. A school operating at 45% load factor during the school year but 15% during summer might show an annual LF around 30%, which understates the operational efficiency of the school-year period.
Load factor by industry: Texas commercial examples
Some brief notes on how load factor shows up across Texas commercial sectors we work with:
Manufacturing
Multi-shift operations tend to have high load factor (65% to 85%). Single-shift operations can drop into the 30% to 50% range. Improving load factor for manufacturers often means adding shifts (where profitable), staggering equipment startup, and shifting flexible processes to off-peak hours. Our manufacturing electricity procurement guide for Texas covers shift scheduling, demand management, and how load factor affects supply pricing for manufacturers.
Cold storage and warehousing
Refrigeration must cycle continuously, which produces steady base load. Peak occurs when multiple compressors are running simultaneously. Sequencing compressor cycles to avoid coincident starts is the highest-leverage intervention. Load factor for cold storage tends to be 60% to 80%. Our warehouse and cold storage electricity procurement guide walks through the specifics.
Restaurants and food service
Sharp meal-period peaks separated by long shoulder hours produce load factors typically in the 25% to 45% range. The economic reality of restaurant operation makes major load factor improvement difficult. Focus instead on managing the peak: staggered kitchen equipment, HVAC pre-cooling before dinner service, and (for high-demand accounts) sequencing rooftop unit cycling. See our sector-specific overview at Texas restaurant electricity strategy.
Schools
Load factor for schools tends to be 25% to 40% during the school year and much lower during summer, producing an annual LF often around 25% to 30%. HVAC scheduling and calendar-driven demand shape are the primary considerations. See our schools and educational electricity guide for Texas.
Real estate and multi-site portfolios
Load factor varies dramatically across a real estate portfolio depending on tenant mix and building type. Portfolio-level procurement can aggregate loads and produce blended load factors that improve pricing for the whole portfolio. See our Texas commercial real estate electricity procurement resource.
For sector-specific overviews across all Texas commercial verticals, the energy strategy by industry hub covers each one.
Frequently asked questions
What is load factor in commercial electricity?
Load factor is the ratio of a facility's average electricity demand to its peak electricity demand over a specified period, expressed as a percentage. It measures how consistently the facility uses electricity. High load factor means steady consumption; low load factor means sharp peaks separated by low-usage periods.
How do I calculate my business load factor?
Load Factor (%) = kWh ÷ (Peak kW × Hours in period) × 100. For a 30-day monthly billing period, use 720 hours. For an annual calculation, use 8,760 hours. Pull the kWh and peak kW figures directly from your commercial electricity bill. For accounts with interval data available through Smart Meter Texas, more precise calculations are possible using 15-minute interval readings.
What is a good commercial load factor?
There is no universal answer; appropriate load factor depends on the type of business. Continuous manufacturing and data centers typically operate at 65% or higher. Offices and retail operate at 30% to 45%. Restaurants and schools operate at 25% to 40%. Houses of worship and event venues can be below 20%. What matters is understanding whether your load factor is consistent with the operational profile your business requires.
Why does load factor affect my electricity rate?
Two mechanisms. First, some Texas TDSP tariffs (Oncor's Secondary Service Greater Than 10 kW schedule, for example, for accounts above 20 kW) directly use annual load factor bands to set the distribution system charge. Higher load factor produces a lower rate on that tariff. Second, competitive REPs price supply contracts to reflect the cost of hedging your specific load shape. High-LF loads are easier to hedge, so REP quotes tend to come in tighter. Both mechanisms typically apply simultaneously.
How to improve commercial load factor?
The primary approach is reducing peak demand relative to average demand: stagger equipment startups, shift flexible loads to off-peak hours, install demand controls, use HVAC pre-cooling and setpoint management, and (for larger facilities) consider battery peak shaving. Raising average demand also improves load factor if the additional load is independently justified and doesn't add to peak. Adding load solely to improve load factor rarely produces net savings.
What is the difference between load factor and power factor?
Load factor measures average demand against peak demand over time (a demand-shape metric). Power factor measures real power (kW) against apparent power (kVA) at any given moment (an electrical engineering metric related to motor loads and reactive power). They are independent measurements. A facility can have high load factor and poor power factor, or vice versa.
What is the difference between load factor and capacity factor?
Capacity factor is usually a generation-side metric that measures a power plant's actual output against its theoretical maximum. Load factor is a demand-side metric that measures a consumer's average demand against peak demand. The math is similar but the applications are different.
Does higher load factor always mean lower electricity cost?
Directionally yes for most Texas commercial customers, but not universally. For customers on TDSP rate schedules that use load factor bands (like Oncor Secondary Service Greater Than 10 kW), higher LF directly reduces the distribution charge. For competitive supply pricing, higher LF generally improves REP quotes. But for a customer on a rate schedule that doesn't reference load factor, and where the REP has already priced the load shape, incremental LF improvement may have limited direct effect. The specific tariff and contract terms matter.
Where do I find peak kW on my Texas commercial bill?
On demand-metered commercial bills, peak kW typically appears in the meter information section, often labeled as "Peak Demand," "Billing kW," "NCP kW," or "Maximum Demand." It's the highest 15-minute average demand recorded during the billing period. If you can't find it, the account may not be on a demand-metered schedule; small commercial accounts below the demand threshold are billed volumetrically without a peak kW measurement.
How does load factor affect my TDSP delivery charges?
For accounts on TDSP tariffs that use annual load factor bands (like Oncor Secondary Service Greater Than 10 kW), load factor directly determines which band applies and therefore the per-kW rate for the distribution system charge. The applicable Oncor 2026 schedule for accounts above 20 kW ranges from approximately $9.83/kW for 0-10% LF to approximately $6.93/kW for 26%+ LF. For accounts on tariffs that don't use LF bands, load factor doesn't directly change the delivery charge but still affects demand-driven costs.
Do all Texas TDSPs use load factor in their rate schedules?
No. Oncor's Secondary Service Greater Than 10 kW schedule uses annual load factor bands for accounts above 20 kW. CenterPoint, AEP Texas Central, AEP Texas North, and TNMP each have their own commercial rate schedules with different structures. Some use straight-line demand rates without LF bands; some use different threshold structures. Verify the applicable tariff for your account at the TDSP's website or through the PUCT rate information at puct.texas.gov.
How much can improving load factor save?
For a Texas Oncor commercial account with 100 kW billing demand, moving from a 5% annual LF band to a 26%+ band produces a distribution system charge reduction of approximately ($9.83 − $6.93) × 100 = $290 per month or ~$3,480 per year, based on the tariff structure. That's regulated delivery savings alone, before any effect on competitive supply pricing. Actual savings depend on the specific tariff, current effective rates, and account characteristics.
Does load factor matter for shopping electricity contracts?
Yes. Providing REPs with clean historical load factor data (and 12 months of interval data) produces tighter, more accurate quotes than working from generic assumptions. High-LF loads generally receive better pricing because they're easier to hedge; low-LF loads generally price wider. Preparing your load data before requesting quotes is one of the highest-return steps in commercial energy procurement.
Is load factor the same as usage profile?
Related but not identical. Load factor is a single-number summary of demand shape (average ÷ peak). Usage profile is the full picture of how your load varies across hours, days, weeks, and seasons. Two facilities can have the same load factor but very different usage profiles (one weekday-focused, one weekend-focused, for example). For procurement purposes, load factor is a useful summary metric; the full interval-data usage profile is what REPs actually use to price a supply contract.
Where does load factor appear on the electricity bill?
Load factor is not usually a labeled line on a Texas commercial electricity bill. It's derived from the kWh, peak kW, and billing days that do appear on the bill. Some REPs include a "load factor" line as an informational note; most do not. If your bill doesn't show it, calculate it using the formula.
Where to go from here
If load factor has been an abstract concept for your business until now, three practical steps:
- Calculate your monthly and annual load factor using the formula in this guide and 12 months of billing history. The math takes ten minutes with a spreadsheet.
- Identify your peak intervals. Pull 15-minute interval data from Smart Meter Texas for your highest-usage months and identify which intervals set your monthly peaks. Match those against your operational calendar. This is the starting point for any load factor improvement program.
- Verify your applicable tariff. If you're on a TDSP schedule that uses load factor bands (Oncor Secondary Service Greater Than 10 kW is the clearest example), verify which band your account currently sits in and calculate the potential savings from moving up. Our overview of TDSP delivery charges across Oncor, CenterPoint, AEP Texas, and TNMP covers each utility's structure; the Oncor commercial delivery page covers this specific schedule.
- Prepare a clean data package before shopping supply. When you're ready to run a procurement RFP, having 12 months of kWh, peak kW, calculated load factors, and interval data produces materially better quotes than working from generic assumptions.
Electric Decisions works with Texas commercial buyers on supplier-neutral procurement RFPs that use complete load factor and interval data to source quotes from more than 46 REPs. The commercial electricity comparison for Texas businesses benchmarks those quotes against the live ERCOT forward curve, so you're comparing apples to apples on total delivered cost, not just headline supply rate. And our bill analyzer for Texas commercial electricity automates the initial reconciliation between what your load factor should be producing and what you're actually being charged.
Load factor doesn't determine your electricity rate on its own. But it's one of the most influential inputs, and understanding your own is a prerequisite to making any well-founded procurement decision. The businesses that treat it that way consistently pay less than the ones that focus only on the headline ¢/kWh number.
