The Bill Nobody Saw Coming
A bakery owner in Columbus opens her July electricity bill and does a double-take. Production was the same as June. The weather was similar. But the bill jumped significantly. The culprit, buried in the middle of the statement, is a demand charge triggered by a single fifteen-minute window when the ovens, the walk-in cooler compressor, and the espresso machine all ran at once.
That scenario plays out in commercial buildings across Texas, Ohio, Pennsylvania, Massachusetts, New Jersey, and Washington DC every month. Business electricity tariff prices are not a single number. They are a structure, and understanding that structure is what separates businesses that manage energy costs from those that simply absorb them.
What a Business Electricity Tariff Actually Is
A tariff is the formal schedule of rates and rules your utility files with its state regulator. For commercial accounts, the document covers every charge that can appear on your bill. The regulator overseeing those filings differs by state: the Public Utility Commission of Texas (PUCT) governs Texas utilities, the Public Utilities Commission of Ohio (PUCO) governs Ohio, the Pennsylvania Public Utility Commission (PA PUC) covers Pennsylvania, the Massachusetts Department of Public Utilities (MA DPU) covers Massachusetts, the New Jersey Board of Public Utilities (NJBPU) covers New Jersey, and the DC Public Service Commission (DC PSC) covers the District.
In every one of those six markets, the tariff splits into two sides. Delivery covers wires, meters, maintenance, and reliability programs. That side stays with your local utility no matter what. Supply covers the electricity commodity itself, and in deregulated markets supply is shoppable. Businesses can replace the utility's default supply price with a contract from a licensed retail energy supplier, often locking in a fixed rate for one to three years.
Default Supply Has a Different Name in Every State
One of the most common misconceptions in commercial energy is that the default utility rate is called the same thing everywhere. It is not, and confusing the names can lead to apples-to-oranges comparisons.
In Texas, the default is called the Price to Compare, set by the PUCT for each utility territory. In Ohio, utilities offer a Standard Service Offer (SSO). In Pennsylvania, the default is called the Price to Compare as well, but the PA PUC sets it through a separate process from Texas. In Massachusetts, the MA DPU oversees Basic Service rates, which utilities update periodically. In New Jersey, the NJBPU governs Basic Generation Service (BGS). In Washington DC, the DC PSC oversees Standard Offer Service (SOS).
Each default is recalculated on its own schedule, anywhere from monthly to semi-annually depending on the state. The current default in your territory is the baseline to beat when you shop.

The Components Every Commercial Tariff Includes
Beyond the basic energy charge measured in cents per kilowatt-hour, commercial tariffs layer in several additional line items.
Customer charge. A flat monthly fee that covers meter reading, billing administration, and basic service infrastructure. It appears regardless of how much electricity you use.
Distribution charge. A per-kilowatt-hour charge for moving electricity from the transmission grid to your building. This is the core of the delivery side.
Transmission charge. Covers the high-voltage lines that carry bulk power across regions. This charge flows through your utility bill even when you buy supply from a third party.
Riders and surcharges. Each state allows utilities to recover specific costs through separate line items. These can include energy efficiency program costs, renewable portfolio standard compliance, infrastructure modernization programs, and storm-recovery fees. Riders vary significantly by utility and state.
Demand charge. This is the component that most often surprises small business owners who have only ever had residential service. Demand charges apply above each utility's threshold (measured in kilowatts), and they are calculated on the highest fifteen-minute average power draw recorded during the billing period. A single high-usage spike, even one that lasts just a few minutes, sets the demand figure for the entire month.
Demand Charges: The Hidden Driver of Commercial Bills
Utilities impose demand charges because the grid must be built to handle peak load, not average load. If your facility could theoretically draw a large surge of power at any moment, the utility has to have that capacity ready. The demand charge is how it recovers that infrastructure investment.
The threshold at which demand charges kick in varies by utility and tariff class. Some commercial tariffs apply demand charges starting at relatively modest peak draws; others have higher thresholds designed for small general service accounts. Once you cross the threshold, the charge per kilowatt of demand can represent a meaningful portion of your total bill, sometimes exceeding the energy charge on months when usage is otherwise moderate.
Reducing demand charges is a separate discipline from reducing kilowatt-hour consumption. Businesses that address both tend to see the biggest bill improvements. Common strategies include staggering equipment startup times, programming HVAC setbacks during early morning hours, and identifying which processes create simultaneous load spikes. An energy audit from a licensed professional can map exactly where your peak demand is generated.
How Deregulation Affects What You Pay
In all six markets covered here, deregulation separates the supply side from the delivery side. Your local utility still owns the wires and remains responsible for reliability, but you choose who sells you the electricity commodity.
Retail suppliers compete for commercial accounts by offering structures that utilities generally cannot match. Common commercial supply products include fixed-rate contracts (the same cents-per-kilowatt-hour for the contract term), index-based or market-following rates (which move with wholesale prices), and block-and-index hybrids that fix a portion of your load while leaving the rest floating.
For small and medium businesses, fixed-rate contracts typically offer the most predictable budgeting. Larger commercial accounts with sophisticated energy management may find value in indexed products when wholesale prices are favorable, but those accounts accept price volatility as a tradeoff.
The supply charge is only part of what you pay. Even with a competitive supplier, delivery charges, demand charges, riders, and the customer charge remain on your bill exactly as the utility tariff specifies. A supplier cannot reduce those components. What they can do is offer a competitive supply rate that, combined with smart load management, lowers your overall electricity spend.
How Tariff Prices Differ Across the Six Markets
Business electricity tariff prices vary considerably across Texas, Ohio, Pennsylvania, Massachusetts, New Jersey, and Washington DC. The variation reflects differences in fuel mix on each regional grid, transmission infrastructure, state policy mandates, and how each state structures its default supply procurement.
Massachusetts and New Jersey tend to carry higher all-in costs than Texas and Ohio, largely because of grid fuel mix, infrastructure costs, and state program surcharges. Pennsylvania and DC fall somewhere in between depending on utility territory and tariff class. None of that means a business in a historically higher-cost state cannot find a competitive supply rate. Deregulation exists precisely to introduce price competition.
Because rates shift with wholesale markets, seasonal demand, and policy changes, the only reliable way to compare current tariff prices is to pull live quotes. ElectricRates.org maintains current business electricity rates across all six deregulated markets, updated as market conditions change.
What to Read Before Signing a Supply Contract
Rate is not the only variable in a commercial supply agreement. Before signing, business owners should confirm several additional terms.
Contract length. Terms typically run twelve, twenty-four, or thirty-six months for small commercial accounts. Longer terms lock in your rate but limit flexibility if your load profile changes.
Early termination fees. Most fixed-rate contracts carry penalties for early exit. Understand the fee structure before committing, especially if your lease or business operations could change.
Automatic renewal clauses. Some contracts roll to month-to-month or renew at a new fixed rate unless the customer provides written notice within a specific window. Missing that window can result in unfavorable pricing.
Pass-through versus fixed delivery adders. Some retail supply quotes bundle certain delivery-related costs into the supply price. Others pass them through at cost. Clarify which model your quote uses so you can compare offers accurately.
Supplier license status. Each state regulator maintains a public list of licensed retail electricity suppliers. Confirming your supplier appears on the appropriate state list (PUCT in Texas, PUCO in Ohio, PA PUC in Pennsylvania, MA DPU in Massachusetts, NJBPU in New Jersey, DC PSC in DC) protects your business from unlicensed operators.
Taking Action on Your Business Electricity Tariff
Understanding how your tariff is structured is step one. Acting on that understanding is where the work happens.
Start by pulling your last twelve months of utility bills. Note the demand charge line on each one, and identify the months when demand was highest. That pattern often reveals specific operational causes, typically HVAC startup in summer or heating equipment in winter combined with morning production loads.
Next, find out what your utility's current default supply rate is. Your utility is required to post it. In Texas, check your utility's Price to Compare. In Ohio, check your utility's SSO rate with the PUCO. In Pennsylvania, find the PA PUC Price to Compare for your territory. In Massachusetts, check your utility's Basic Service rate with the MA DPU. In New Jersey, check your BGS rate with the NJBPU. In DC, check the SOS rate with the DC PSC.
Then compare. Use ElectricRates.org to see current retail supplier quotes for your state and utility territory, and evaluate them against what you are currently paying on the supply side. Factor in contract length, termination terms, and any delivery adders before making a decision.
Business electricity tariff prices are not static, and the gap between a well-chosen supply contract and the default rate can be meaningful over a multi-year term. The businesses that check regularly tend to pay less than those that treat electricity as a fixed cost.
