Commodity vs Non-Commodity Energy Costs for Businesses

When businesses review their energy bills, the focus often falls on the commodity cost, the wholesale price of gas or electricity itself. While wholesale energy prices can have a significant impact on overall expenditure, they often represent only one component of a business’s total energy bill. 

In recent years, non-commodity charges have become an increasingly important component of utility bills, often accounting for a large proportion of total energy spend.  

For many organisations, understanding these costs can unlock opportunities to reduce expenditure, improve budgeting accuracy, and make more informed procurement decisions. 

What Are Commodity Costs? 

Commodity costs relate to the energy your business consumes, also known as the price paid for the gas or electricity supplied to your business. 

These costs are influenced by a range of market factors, including: 

• Wholesale energy prices 
• Supply and demand 
• Global energy markets 
• Weather conditions 
• Geopolitical events 
• Generation availability 

Commodity costs are often the element of an energy contract that businesses are most familiar with, particularly when comparing fixed and flexible procurement options. 

However, commodity charges typically represent only one part of the overall cost of supplying energy. 

What Are Non-Commodity Costs? 

Non-commodity costs cover the additional charges associated with delivering energy from generation sources to your site, maintaining infrastructure, and supporting the operation of the wider energy system. 

These charges are largely outside the control of energy suppliers and are set by network operators, regulators, and government schemes. 

Examples of non-commodity costs can include: 

• Transmission charges, including Transmission Network Use of System (TNUoS) charges 
• Distribution charges, including Distribution Use of System (DUoS) charges 
• Balancing and system operation costs 
• Environmental and renewable support schemes 
• Capacity Market charges 
• Metering and data collection costs 

Other common non-commodity costs may include Balancing Services Use of System (BSUoS) charges, Contracts for Difference (CfD) costs, and Renewables Obligation (RO) charges. Together, these charges can help fund and maintain the UK’s energy infrastructure while supporting the transition to a lower-carbon energy system.  

Why Are Non-Commodity Costs Becoming More Important? 

Over the last decade, non-commodity charges have made up an increasingly significant proportion of many business energy bills. 

As the UK energy system continues to evolve, investment in network infrastructure, renewable generation, and energy security initiatives has increased. These costs are often reflected through non-commodity charging mechanisms. 

As a result, organisations that focus solely on wholesale energy prices may overlook a substantial proportion of their total energy costs. Securing a competitive unit rate remains important, but it should be considered alongside the wider non-commodity charges that can significantly influence overall expenditure.  

How Businesses Can Manage Non-Commodity Costs 

While many non-commodity charges are regulated, businesses can take steps to reduce their impact. These include: 

• Reviewing energy procurement strategies regularly  
• Monitoring consumption patterns and peak demand periods 
• Improving energy efficiency across sites 
• Understanding DUoS and TNUoS charging structures 
• Working with an energy consultant to identify cost-saving opportunities  

By taking a proactive approach, organisations can improve cost visibility and minimise avoidable expenditure.  

The Importance of Looking Beyond Unit Rates 

When renewing an energy contract, it can sometimes be tempting to focus entirely on securing the lowest available commodity price. However, a lower unit rate doesn’t always translate into the lowest overall cost.  

Factors such as site profile, consumption patterns, network charges, and contract structure can all influence the total amount a business pays.  

Understanding how both commodity and non-commodity costs impact your organisation can lead to better-informed decisions and a more effective long-term strategy. 

Where Consultancy Adds Value 

The complexity of non-commodity charging means that many organisations struggle to understand exactly what’s driving their energy costs. 

An experienced energy consultant can help businesses: 

• Gain visibility over all elements of their energy spend 
• Identify charges that have the greatest financial impact 
• Understand how industry changes may affect future costs 
• Build procurement strategies aligned to business objectives 
• Improve budgeting and forecasting accuracy 
• Identify opportunities to reduce unnecessary expenditure 

Rather than focusing only on contract rates, consultancy helps organisations understand the bigger picture. 

Managing Costs in a Changing Energy Landscape 

As energy markets continue to evolve, businesses face increasing pressure to control costs, manage risk, and support sustainability objectives. Having visibility of both commodity and non-commodity costs allows organisations to make more informed decisions and avoid being caught out by unexpected charges. 

FAQs 

What are commodity energy costs?
Commodity costs refer to the wholesale price of the gas or electricity consumed by a business.

What are non-commodity energy costs?
Non-commodity costs include charges related to energy transmission, distribution, system balancing, environmental schemes, and metering services.

Can businesses reduce non-commodity costs?
While many non-commodity charges are regulated, businesses can often reduce their impact through informed procurement strategies, energy management, and expert consultancy.

What are DUoS charges?
Distribution Use of System (DUoS) charges cover the cost of operating and maintaining local electricity distribution networks that deliver power to business premises.

What are TNUoS charges?
Transmission Network Use of System (TNUoS) charges fund the national transmission network that transports electricity across Great Britain. These charges can vary depending on location and usage patterns.

Why should businesses understand non-commodity charges?
Non-commodity costs can make up a significant proportion of total energy spend. Understanding them provides greater visibility, more accurate forecasting, and better procurement decisions.
