The fuel adjustment clause (FAC) plays a significant role in determining monthly energy costs for businesses, yet it’s often misunderstood. This article breaks down what the FAC is, how it impacts commercial utility bills, and actionable strategies to manage variable fuel costs effectively. The energy market is constantly evolving, and fuel prices can fluctuate dramatically. These swings directly impact your utility bills. To better control operational expenses, it’s essential to understand the fuel adjustment clause (FAC). This charge reflects monthly changes in fuel costs used to generate electricity and can significantly affect commercial utility rates. Below, we explain how the FAC works, how it’s calculated, and what strategies businesses can use to manage fuel-related price volatility.
What Is The Fuel Adjustment Clause (FAC)?
The fuel adjustment clause (FAC) is a line item on your utility bill that reflects changes in the cost of fuel used to produce electricity. This mechanism enables the utility or retail energy supplier to transfer fluctuating fuel expenses to customers without modifying the base rate of service. In most cases, the FAC is updated monthly and shifts according to fuel market prices, supply agreement terms, demand fluctuations, and overall generation costs.
Although the fuel adjustment charge is listed separately on your bill, understanding its true impact can be challenging without knowing how to evaluate it properly. Because the FAC can change frequently, your total bill may increase or decrease even when your energy usage remains consistent. Continue reading to see how the FAC is calculated and how it appears on your utility statement.
How Is The FAC Rate Calculated?
The FAC rate is determined by the utility’s real cost to purchase fuel or buy electricity from outside suppliers or the wholesale energy market. These costs are then allocated to customers based on how much energy they use during a specific billing period. If fuel prices rise because of events like natural disasters or supply chain disruptions, the FAC rate will increase to reflect those higher costs. Utilities calculate the FAC by reviewing total fuel expenses over a set timeframe and adjusting the charge accordingly for customers. Several key factors directly influence how this cost is calculated and applied to your bill.
Energy Costs
When fuel prices increase or decrease, the FAC rate changes accordingly. The calculation reflects the cost of fuels such as coal, natural gas, and even certain renewable energy sources used to generate electricity. In deregulated energy states, the FAC can directly affect the utility’s price to compare. This means the rate may adjust monthly, quarterly, or semi-annually based on changing fuel market conditions.
Consumption Levels
The FAC is also influenced by how much electricity a customer uses. Businesses that consume more energy will pay a larger portion of total fuel costs. Understanding the breakdown of your commercial electricity bill can help you identify how much of your total charges are tied to fuel adjustments rather than just usage. Review your bill carefully, including demand charges and other variable line items, to find areas where you may be able to reduce costs.
Does The FAC Rate Change?
Yes, the FAC rate changes often as fuel prices and energy demand shift. Unlike fixed charges, the FAC moves up or down with the market. This means businesses may see higher bills when fuel prices rise. Several factors can cause these changes:
Energy Market Trends
FAC rates can change due to global energy market trends, seasonal demand, and geopolitical events. Extreme weather, new energy policies, or conflicts like the Russia-Ukraine conflict can disrupt fuel supply and increase costs. When supply is tight, prices usually rise.

Commodity Pricing
Fuel and electricity are traded in commodity markets. Utilities often buy energy futures in advance to serve customers. When future prices are high, the FAC can increase. For example, in the PPL Electric Utilities service area, the price to compare increased from about 6.5¢ per kWh to 14.5¢ per kWh in just 18 months due to market price spikes. Businesses should monitor energy market trends and forecasts to prepare for FAC changes. Working with an energy broker or staying informed about commodity pricing can help you plan for future cost increases.
Do All Utilities Calculate FAC the Same?
No, utilities do not all calculate the FAC the same way. Each provider may use a different method. Some use a fixed formula. Others include extra factors, such as fuel purchase contracts, transmission costs, and capacity charges.
Because of this, businesses in different areas can pay very different FAC rates, even if they use the same amount of electricity. There is no single standard. This makes it harder for commercial customers to compare costs, especially if they operate in more than one state or city.
For businesses that want more stable pricing, working with a retail energy supplier may help. Some suppliers offer fixed-rate plans and take on the risk of changing fuel costs. An energy broker can also compare suppliers and contract terms to help find options with more predictable FAC exposure.
How Does the FAC Affect Your Bill?
For commercial customers, the FAC can increase monthly operating costs. This is especially true for energy-heavy industries like manufacturing. Because the FAC is a variable charge, even a small rise in fuel prices can lead to a large increase in your total bill. Here are the main ways it can affect your costs:

Higher Total Energy Costs
The FAC is added on top of your base energy rate. During times of market volatility, this can significantly increase your total cost. A utility bill audit can help you see how much the FAC is affecting your bill and find ways to better manage or negotiate these charges in future contracts.
Surprise Charges
Fuel prices can change quickly. This means the FAC can increase without warning. These sudden changes make budgeting harder. Businesses that want price stability may choose fully bundled fixed-rate contracts to reduce market risk.
Higher Costs During Peak Demand
FAC rates often rise when energy demand is high. During summer and winter, businesses may use more electricity, while fuel prices are also higher. This can lead to much larger bills.
What Can You Do?
Managing the FAC effectively means staying proactive and informed. Here are strategies commercial customers can use to control fuel adjustment costs:
Monitor Market Trends
Keep track of fuel and energy market trends to anticipate changes in FAC rates. Energy forecasts and industry insights, like Great Energy 1’s 2025 energy outlook, can help you plan for potential cost shifts.
Review Contract Terms
Examine your energy contracts carefully. Pay attention to FAC clauses and material change terms to understand how flexible your rates are. An energy broker can help secure contracts with favorable FAC structures for your business.
Energy Efficiency Investments
Lowering overall energy consumption reduces the base on which FAC is calculated. Implement energy efficiency measures and explore incentives or rebates to cut fuel-dependent energy use.
Evaluate Supplier Options
In deregulated markets, switching suppliers or renegotiating contracts can give you a better FAC structure. Suppliers with more predictable or transparent FAC rates may help stabilize costs. Knowing how to switch or renegotiate can significantly impact your energy expenses.
Utility Bill Audits
Regularly auditing your utility bills can uncover errors and highlight savings opportunities in FAC and other charges. Full-service audits can help businesses optimize spending and reduce unnecessary costs.
Conclusion
The Fuel Adjustment Clause (FAC) plays a significant role in determining commercial energy costs, and its volatility can impact monthly utility bills. By understanding how the FAC is calculated, monitoring market trends, reviewing contract terms, investing in energy efficiency, evaluating supplier options, and performing regular bill audits, businesses can better manage these variable costs. Proactive management of the FAC not only helps control expenses but also provides greater predictability in budgeting and long-term energy planning.
