Sports Lighting Power Consumption and Demand Charge Management: A Guide for Facility Energy Managers
An engineering guide for facility energy managers, athletic department CFOs, and parks department directors managing the electrical demand profile of LED sports lighting installations. Covers connected load, peak demand, demand charge structures, and how dimming and zone control reduce both energy and demand costs.
For most athletic facilities, the lighting electric bill has two parts: kWh consumption (energy used) and kW demand charges (peak draw during the billing period). Athletic directors focus on kWh because it’s the bigger number; energy managers focus on kW because it’s the more expensive per unit. LED retrofit cuts both, but specific design decisions determine how much.
This guide covers the demand-side economics of sports lighting and how to structure the project to minimize total electric cost — not just consumption.
The Two Parts of Your Sports Lighting Electric Bill
Charge Type | Unit | Typical Commercial Rate |
Energy consumption | $/kWh | $0.07–$0.30 (varies by region) |
Demand charge | $/kW peak | $8–$25/kW per month |
Time-of-use multipliers | Peak hour rate × multiplier | 1.5–3× for 4–9pm summer hours |
For sports facilities, demand charges can be 30–50% of the total electric bill because lighting is concentrated load (full system on for 3–4 hours per game) rather than continuous draw spread across the day.
Connected Load by Facility Type
Facility (LED) | Connected Load | Peak Demand During Game |
HS Varsity Football (28 fixtures) | 17–22 kW | 17–22 kW |
HS Varsity Baseball (36 fixtures) | 22–28 kW | 22–28 kW |
4-Court Tennis Club (32–40 fixtures) | 15–22 kW | 15–22 kW |
NCAA D-II/III Field (60 fixtures) | 40–55 kW | 40–55 kW |
NCAA D-I Stadium (96 fixtures) | 80–120 kW | 80–120 kW |
Each kW of peak demand carries $8–$25/month in demand charge. A NCAA D-I stadium running 100 kW during games can carry $1,000–$2,500/month in demand charge alone — $12,000–$30,000 annually.
Time-of-Use Rate Impact
Most commercial utility rate structures include time-of-use (TOU) multipliers for peak hours, typically 4–9pm in summer. Sports lighting concentrated in these hours pays peak rates:
Game Schedule | Peak Hour Exposure | Effective Rate Multiplier |
Friday 7pm football | 7pm–10pm peak hours | 1.5–2× standard rate |
Saturday afternoon football | 1pm–5pm partial peak | 1.0–1.5× |
Weeknight HS basketball | 6pm–9pm peak hours | 1.5–2× |
Sunday noon soccer | Off-peak | 1.0× |
How LED Retrofit Reduces Demand Charges
Switching from MH to LED reduces connected load 50–65%. For a facility paying $1,500/month in demand charges, that’s a $750–$975/month reduction — $9,000–$11,700 annually. This is on top of energy consumption savings, often roughly equal in dollar value.
Total electric bill reduction from LED retrofit typically breaks down as:
·~50% from energy consumption reduction
·~40% from demand charge reduction
·~10% from time-of-use rate impact
Smart Controls for Demand Reduction
Smart controls reduce peak demand beyond the LED savings:
Control Strategy | Demand Reduction |
Zone control (multi-court) | 30–50% (light only courts in use) |
Pre-game ramp-up dimming | 5–15% (gradual brighten avoids peak demand spike) |
Halftime dimming | 20–40% during halftime period |
Practice mode at 50–70% | 30–50% during practice vs game |
Demand response participation | Variable (utility incentive program) |
Demand Response Program Participation
Many utilities offer demand response (DR) programs that pay facility customers to reduce load during grid-stress periods (typically summer afternoons during heat waves). Sports facilities can participate by:
·Pre-cooling the facility before peak hours
·Dimming lighting to 70–80% during DR events (visually unnoticeable, financially significant)
·Shifting practice schedules from peak to off-peak hours
·Earning $50–$200/kW reduction per DR event
For a 100 kW facility, DR participation can earn $5,000–$20,000 annually depending on program structure and event frequency.
Specifications That Reduce Demand Charges
Spec | Demand Impact |
0–10V dimming standard | Enables practice-mode dimming |
DMX/sACN for events | Enables event-tier control including halftime dimming |
Zone control hardware | Independent dimming per zone for multi-court / multi-field |
BACnet for BMS integration | Enables coordinated facility-wide demand management |
Demand response controller | Automatic response to utility DR signals |
Pulling It Together
Total electric bill reduction from sports lighting comes from four levers:
1.LED retrofit — 50–65% energy and demand reduction at the fixture level
2.Smart controls — additional 20–50% reduction through scheduling, zoning, and dimming
3.Time-of-use shifting — moving practices to off-peak hours where possible
4.Demand response participation — earning utility incentives for grid-stress event participation
Combined, these can reduce total sports lighting electric cost 65–85% vs the legacy MH baseline. For NCAA D-I and pro stadium facilities, this represents $30,000–$80,000+ annually in operating cost reduction.

Frequently Asked Questions
What's the demand charge on a sports lighting facility?
Demand charges are typically $8–$25/kW per month at commercial rates. A NCAA D-I stadium running 100 kW during games carries $800–$2,500/month in demand charge alone, $9,600–$30,000 annually. For sports facilities specifically, demand charges represent 30–50% of total electric bill because lighting is concentrated load rather than continuous draw.
How much does LED retrofit reduce demand charges?
LED reduces connected load 50–65%. For a facility paying $1,500/month in demand charges, that’s a $750–$975/month reduction, $9,000–$11,700 annually. This is on top of energy consumption savings. Total electric bill reduction from LED retrofit breaks down as ~50% from energy consumption reduction, ~40% from demand charge reduction, ~10% from time-of-use rate impact.
What's the impact of time-of-use rates on sports lighting?
Most commercial utility rate structures include time-of-use multipliers for peak hours (typically 4–9pm in summer). Friday night football at 7–10pm pays 1.5–2× standard rates. Saturday afternoon football at 1–5pm pays 1.0–1.5×. Weeknight HS basketball at 6–9pm pays 1.5–2×. Sunday noon soccer is off-peak. Schedule shifts to off-peak hours can reduce effective rates 30–50%.
How do smart controls reduce peak demand?
Five strategies: zone control (multi-court facilities, 30–50% reduction by lighting only courts in use); pre-game ramp-up dimming (5–15% reduction by avoiding demand spike); halftime dimming (20–40% during halftime); practice mode at 50–70% output (30–50% reduction during practice vs game); demand response participation (variable utility incentive).
Can sports facilities participate in utility demand response?
Yes. Many utilities offer demand response programs paying facilities to reduce load during grid-stress periods. Sports facilities participate by pre-cooling, dimming lights to 70–80% during DR events (visually unnoticeable), shifting practice schedules from peak to off-peak, and earning $50–$200/kW reduction per DR event. A 100 kW facility can earn $5,000–$20,000 annually.
What spec enables demand charge management?
Five specs: 0–10V dimming standard (enables practice-mode dimming); DMX/sACN for events (event-tier control including halftime); zone control hardware (independent dimming per zone for multi-court/multi-field); BACnet for BMS integration (coordinated facility-wide demand management); demand response controller (automatic response to utility DR signals). Combined, these enable 65–85% total electric cost reduction vs MH baseline.
