No. Rate classification is determined by meter type and building use, not business size. A small office still gets commercial rates. However, very small commercial customers sometimes negotiate better rates with suppliers by aggregating with other similar businesses or accepting less customization.
Residential vs Commercial Electricity Rates in Ohio: Key Differences Explained
Why does business electricity cost more than home electricity in Ohio? The answer lies in how utilities and suppliers structure rates for different customer segments. Understanding these differences—from demand charges to volume pricing—helps both homeowners and business owners evaluate their bills accurately and identify savings opportunities.
Decoding Your Ohio Electric Bill: Are You Paying the Right Price?
Comparing residential and commercial electricity rates is challenging because they're structured completely differently. Residential rates are typically simple per-kWh charges. Commercial rates include multiple components: base charges, per-kWh energy charges, and demand charges—creating a much more complex pricing structure.
Simple Residential Rate Structure
- Base/Service Charge: $10-20/month (fixed monthly fee)
- Energy Charge: $0.10-0.15/kWh (per kilowatt-hour used)
- Total Bill: Base + (Usage × Rate) + Taxes
- Example: 1,000 kWh @ $0.12/kWh = $120 + base = ~$135
Complex Commercial Rate Structure
- Base/Service Charge: $50-300+/month
- Energy Charge: $0.08-0.14/kWh
- Demand Charge: $8-20/kW of peak usage
- Capacity Charge: $0.02-0.15/kWh (varies by season)
- Transmission/Distribution: Additional per-kWh charge
- Example: 50,000 kWh/month, 500 kW peak = $3,500-5,000+
This complexity is why many businesses overpay—they don't understand the rate components or recognize opportunities for demand reduction.
Volume & Demand: The Core Reasons Your Business Rate Isn't the Same as Your Home's
Three fundamental differences explain why commercial rates differ from residential rates:
1. Demand Charges (Unique to Commercial)
Your business peak demand—the highest kW your facility uses in a single hour—determines a substantial portion of your bill. A 500 kW peak × $15/kW = $7,500 monthly demand charge, regardless of when the peak occurs. Residential customers don't have demand charges; they only pay for kWh used.
2. Volume Economics
Residential customers use 10,000-15,000 kWh annually. Commercial customers use 50,000-500,000+ kWh. Larger volume creates negotiating power and allows suppliers to operate at lower margins. However, it also means infrastructure costs are distributed across fewer transactions, so per-kWh rates may not scale as much as volume increases.
3. Load Profile Differences
Residential loads are predictable (homes use power 24/7, heating/cooling). Commercial loads are often concentrated during business hours with evening/weekend reduction. This concentration makes commercial loads harder to serve efficiently, requiring more infrastructure capacity during peak periods.
4. Ancillary Service Costs
Commercial customers access more granular pricing, better forecasting, and supplier relationships. These services cost money. Additionally, commercial operations are more complex—factories, multi-site aggregations, and special rate requests require customized analysis from suppliers and utilities.
| Rate Component | Residential | Commercial | Why Different |
|---|---|---|---|
| Base Charge | $10-20/month | $50-300+/month | Complex metering and service infrastructure |
| Energy Rate | $0.10-0.15/kWh | $0.08-0.14/kWh | Varies; may be lower/higher based on volume |
| Demand Charge | None (or minimal) | $8-20+/kW | Utility must provision capacity for peak demand |
| Negotiability | None; fixed utility rates | High; competitive suppliers offer custom pricing | Competition creates flexibility |
| Contract Length | Month-to-month | 12-36 months typical | Suppliers invest in long-term relationships |
Understanding Ohio's 'Price to Compare': The Secret Number on Your Bill Explained
Your utility bill displays a "Price to Compare" (PTC) rate—the regulated default rate for your customer class. This baseline helps you evaluate whether competitive suppliers offer value.
What the PTC Really Means
- It's a starting point: The PTC is the highest regulated rate your utility can charge before you switch to a competitor.
- It includes everything: PTC incorporates energy, capacity, ancillary services, and all fees—a single "all-in" rate.
- It varies by customer class: Residential, small commercial, and large industrial customers have different PTCs.
- It changes periodically: Utilities request PUCO approval for rate changes; PTCs are updated based on rate cases.
- It's not truly comparable: Different utilities in different areas have different PTCs, and competitive suppliers may unbundle rates differently.
For commercial customers, the PTC is critical. Many businesses don't realize they can switch suppliers and access rates 15-30% below the PTC. This single number represents thousands in annual savings opportunities.
Example: Understanding Your PTC
If your PTC is $0.085/kWh and you use 100,000 kWh annually:
- Annual cost at PTC: 100,000 × $0.085 = $8,500
- Supplier offer at $0.072/kWh: 100,000 × $0.072 = $7,200
- Annual savings: $1,300 (15% reduction)
If your business overlooks this switch and stays at the PTC rate, you lose $1,300+ annually—money that suppliers gladly share with customers who shop competitively.
Beyond the Standard Rate: How Ohio Businesses Can Unlock Huge Savings on Commercial Energy
Simply switching from utility rates to competitive supplier rates often isn't enough to maximize savings. Strategic energy management multiplies the benefit.
Strategy 1: Demand Reduction
Every 1 kW reduction in peak demand saves $8-20/month ($96-240 annually). A 50 kW reduction saves $400-1,200 annually just from demand charges. Capacity charges make demand reduction even more valuable during peak seasons.
Strategy 2: Load Shifting
Time-of-use rates reward businesses that shift operations away from peak hours. Moving 20% of usage from $0.15/kWh peak to $0.08/kWh off-peak saves 7% on energy charges alone.
Strategy 3: Multi-Site Aggregation
Businesses with multiple locations can consolidate supply procurement, increasing negotiating power with suppliers. Aggregating 5 sites at 50 kW each (250 kW total) gets better rates than procuring each site individually.
Strategy 4: Renewable Selection
Green energy plans often cost less than standard plans. Choosing renewable energy supports sustainability while saving money—a rare win-win in energy procurement.
Strategy 5: Contract Structure
Choosing between fixed and variable rates, contract length, and early termination terms significantly impacts total cost. Get multiple quote structures (12-month fixed, 24-month fixed, variable) and compare total costs across scenarios.
Strategy 6: Energy Audits and Efficiency
Professional energy audits identify waste. Fixing problems (equipment upgrades, process optimization, controls) reduces consumption by 10-25%, multiplying the savings from supplier switching.
A business that switches suppliers (15% savings) + reduces demand (10% savings) + implements efficiency (15% savings) achieves a combined ~35-40% total bill reduction—far more than supplier switching alone.
Commercial vs Residential Rate FAQs
Lower per-kWh rates for commercial customers reflect volume economics and that larger customers have more negotiating power. However, when you add demand charges and other fees, total commercial costs are often much higher than residential. The per-kWh rate alone doesn't tell the full story.
Some businesses have inflexible loads (hospitals, 24/7 operations, data centers). In these cases, focus on energy efficiency (reducing total kWh) and supplier switching for better rates. Demand charges are fixed costs you can't control, so prioritize what you can optimize.
Annually at minimum. More aggressive businesses shop quarterly or when contract renewal approaches. Market conditions change; rates available in Q4 might be 5% better or worse than Q2 rates. Regular shopping ensures you maintain competitive pricing.
No official minimum, but suppliers focus on customers with meaningful annual consumption (typically 10,000+ kWh/year). Very small businesses might have fewer supplier options or less customization available, but switching is still possible and valuable.
