Energy Pass-Through Charges

If your business is in a state where energy is deregulated, you might have the option to choose a retail energy supplier. While this can give you more control over your energy costs, you may encounter an energy pass-through charge.

These charges are additional costs that might appear on your energy bill. Sometimes, they are legitimate and based on the structure of your energy contract. Other times, they could be mistakes—or even scams.

This article explains energy pass-through charges, how they work, and what to look for. By the end, you’ll know whether passing through certain charges could benefit your business or if you’ve been unfairly charged. Understanding this can help you make informed decisions and avoid potential energy billing scams.

What Are Energy Pass-Through Charges?

Energy pass-through charges are extra fees that your energy provider may add to your bill. These charges come from the costs your provider pays in the wholesale energy market and are then “passed through” to you as the customer.
These charges can sometimes be planned and listed in your energy contract, while they might be unexpected at other times. It all depends on the terms of your agreement.

Let’s look at how energy suppliers add these pass-through charges to your bill and what they mean for you as a customer.

Examples of Pass-Through Costs in Electricity Bills

When you pay your electricity bill, some charges are based on costs the electricity industry faces when delivering energy. These costs can change due to market conditions and are passed on to you. Below are examples of these costs, divided into reactionary (unexpected) and ancillary (expected).

Reactionary (Unexpected) Costs

These are costs that come up suddenly and can impact your electricity rates:
  • Regulatory decisions or changes in law: If the government changes a law or regulation, your electricity supplier may have to adjust your price to cover new costs.
  • Weather: Extreme temperatures, like a very cold winter or hot summer, can increase demand or affect supply, leading to higher costs.
  • Material deviation: If a customer significantly changes the amount of electricity they use over time, suppliers must adjust for this unexpected shift in demand.

Ancillary (Expected) Costs

These are planned costs necessary to maintain the electricity system and ensure it runs smoothly:
  • Capacity: This cost helps ensure there’s enough power available during peak times, like hot afternoons when air conditioners are running at full blast.
  • Network Integration Transmission Services (NITS): These charges cover the costs of moving electricity over the grid, which grid operators manage.
  • Balancing: This reflects adjustments when electricity use doesn’t match the predicted amount. Depending on your grid operator, it may appear as a charge or credit.
  • Congestion: These costs arise from getting power to densely populated areas where the grid is busier.
  • Reliability Must Run (RMR) is a fee to keep the grid reliable during emergencies, such as extreme weather when power demand spikes.

What You Should Know About Pass-Through Costs

Pass-through costs are extra charges that energy suppliers add to your bill. These costs vary from supplier to supplier, and there’s no standard rule for applying them. This makes it crucial to carefully research your options before choosing a supplier and pricing plan. Here’s what to keep in mind:

How Much Do Pass-Through Costs Impact Your Energy Bill?

Pass-through costs can vary, but they often make up a significant part of your energy bill. Ignoring them could lead to surprises when your bill arrives.

How Can You Manage These Charges?

It’s easy to overlook pass-through charges in your energy contract, but managing them is essential to avoid unnecessary expenses.
  • Energy Efficiency: Many businesses already take steps to save energy, like reducing usage during peak times. This also helps lower pass-through costs.
  • Regular Audits: Reviewing your energy bills regularly can help you track these charges and identify ways to control them.

What Should You Look For in an Energy Contract?

When comparing energy contracts, make sure you’re getting a fair deal by following these tips:

  • Compare Apples-to-Apples: Ensure the electricity capacity pricing is clear and consistent.
  • Check Contract Terms: Avoid contracts that allow unexpected price changes, such as fees not linked to law changes.
  • Trust the Experts: Working with a trusted energy advisor can help avoid risky or unclear terms in the agreement.

Types of Electricity Pass-through Costs

Electricity bills for domestic customers include pass-through costs, which cover the expenses of delivering electricity to homes. These costs are regulated and not set by electricity suppliers.
They fall into two main categories:

1. Distribution Charges (DUoS – Distribution Use of System)

    • These charges cover the cost of delivering electricity from the transmission network directly to homes.
    • NIE Networks, the company responsible for maintaining and operating the electricity distribution infrastructure in Northern Ireland, applies these charges.
    • The cost includes expenses related to maintaining power lines, substations, and local network infrastructure to ensure reliable electricity supply.

2. Transmission Charges (TUoS – Transmission Use of System)

  • These charges cover the cost of high-voltage electricity transmission from power stations to the local distribution network.
  • The System Operator for Northern Ireland (SONI) manages this process and applies the charges.
  • Costs include managing the flow of electricity across the grid, maintaining system stability, and ensuring power is transmitted efficiently across long distances.
Both DUoS and TUoS charges are regulated and included in electricity bills, ensuring the safe and reliable delivery of power to homes across Northern Ireland.

Types of Energy Contract Pass-Throughs

Pass-through charges are additional costs that might appear on your energy supplier’s electricity or natural gas bill. Let’s break down the most common types of these charges.

Hybrid Energy Contracts

Sometimes, your energy contract allows suppliers to pay you extra costs. This is especially true for Transmission (moving electricity) costs and Capacity (ensuring enough electricity is available).

Here’s how it works:

  • Fixed-Price Contracts: Suppliers might add these costs when needed, even if your contract has a fixed rate.
  • Customer Choice: In some cases, customers can choose to have specific charges (like transmission fees) passed through directly. This avoids the extra fees suppliers might add when bundling these costs into the fixed rate.

Why this helps larger customers:

Big energy users, like factories or businesses, often save money directly by paying for transmission and capacity costs rather than letting the supplier bundle them with extra profit margins.

Fixed-Rate Energy Pass-Through Charges

Even with a fixed-rate contract, suppliers might add extra costs they face in the wholesale energy market. These costs are usually for Transmission and Capacity rather than electricity or gas. (If you want to learn more about Natural Gas Brokers and Electricity Supply Brokers, click here).

Why does this happen?

Energy markets are unpredictable, and costs can change. Suppliers sometimes pass these changes on to customers, which has led to complaints because “fixed-rate” contracts aren’t always indeed fixed.

What are “Super Fixed” Products?

Some suppliers, like AEP Energy, offer “super fixed” contracts. These guarantee no extra charges for transmission or capacity but usually come with a higher price upfront.

Post-Term Rates

When your fixed-rate contract ends, your supplier may switch you to a default or market-based rate.

  • What’s the catch? This new rate is often much higher than your previous fixed rate.

This is a pass-through charge because the supplier takes their wholesale costs, adds a margin, and passes it directly to you.

How to Avoid Extra Energy Fees for Your Business

Many businesses want to save money on energy costs, but it can be tricky to avoid extra charges like pass-through fees. These are additional costs that energy suppliers sometimes add to your utility bill. Luckily, good energy brokers can help you avoid them. Here’s how:

Renew Your Energy Contract on Time

If your contract ends and you don’t renew it promptly, your supplier may switch you to a higher, post-term rate. To avoid this, make sure to renew your contract before it expires.

Let Your Broker Handle Negotiations

A knowledgeable energy broker can talk to suppliers on your behalf. They’ll negotiate better terms and ensure your contract doesn’t include pass-through fees. (If you want to learn more about Lifecycle Electricity Brokerage Deal Negotiation Contract Signing, click here).
