Energy Cost Stack

Energy Cost Stack

Understanding what makes up your business energy bill is essential if you want to control costs effectively. While many organisations focus purely on the unit rate, the reality is that your total energy spend is made up of multiple components -- often referred to as the “energy cost stack.” By breaking this down, businesses can identify opportunities to reduce costs and make more informed procurement decisions.


Wholesale Energy Costs

At the base of the stack is the wholesale cost of energy. This is the price suppliers pay to purchase gas and electricity from the market. It is typically the largest variable element of your bill and is influenced by global supply and demand, geopolitical events, and seasonal factors.


As wholesale prices fluctuate, timing your contract correctly can have a significant impact on what you pay. Locking in rates at the right moment can protect your business from market volatility.


Network and Distribution Charges

Energy arrives at your premises after having been transported via the UK’s infrastructure. Network charges cover the cost of maintaining and operating the electricity grid and gas pipelines. In recent years, large upgrade projects have been undertaken to upgrade this network in order to be able to accommodate an increased amount of renewable energy. This has led to the cost of network charges rising significantly.


These charges include Transmission Network Use of System (TNUoS) and Distribution Use of System (DUoS) costs, which vary depending on your location, usage patterns, and time of consumption. For some businesses, particularly those with high or peak-time usage, these charges can represent a substantial portion of the total bill.


Environmental and Government Levies

A growing part of the energy cost stack comes from environmental and policy-related charges. These include schemes designed to support renewable energy generation and reduce carbon emissions.

Examples include the Renewables Obligation (RO), Feed-in Tariffs (FiTs), and Contracts for Difference (CfD). While these charges support the UK’s transition to net zero, they are ultimately passed on to businesses through their energy bills.


Supplier Costs and Margins

Suppliers also include their own operating costs and margin within your unit rate and standing charge. This covers billing, customer service, risk management, and profit. While this portion is typically smaller than wholesale or network costs, it can vary between suppliers and contract types.


This is why comparing offers from multiple suppliers is so important. Small differences in margin can add up over the life of a contract.


Non-Commodity Costs and Hidden Charges

Beyond the headline rates, there can be additional costs that are less visible but equally important. These may include standing charges, capacity charges, and penalties linked to contract terms such as exceeding agreed usage.


Understanding these elements is key to avoiding unexpected costs. For example, a contract with a low unit rate but high standing charges may not be the most cost-effective option.


Why the Energy Cost Stack Matters

By understanding the full energy cost stack, businesses can move beyond simply chasing the cheapest headline rate and instead focus on overall value. It allows for smarter procurement decisions, better budgeting, and more effective cost control.


Working with an energy broker can make this process far simpler. A broker can break down supplier quotes, highlight where costs are coming from, and identify opportunities to optimise your energy strategy. Whether that’s through better timing, improved contract structures, or ongoing cost management.

With consumer spending declining and OFGEM raising their price cap, you would be forgiven for seeing February as a month where negative news was at the forefront, but in the energy markets, this was not the case.

In a year that began with falling energy prices, there were recurring catalysts that led to prices climbing steadily higher. Geopolitical uncertainty and the perennial threat of escalating conflicts meant fear would maintain a constant presence in the wholesale markets. We will look back at the key energy stories from 2024, and how the energy markets are likely to shape up in 2025. Quarter 1  The year began with cautious optimism as the UK’s gas reserve levels were healthy and prices for the Summer’24 season were in freefall. In February, prices pulled back to their lowest levels since 2021, and for the first time in a while, we identified that there was greater potential for upside risk than for further downward price movement: “ there now (exists) an asymmetrical element of risk should the market encounter a supply-side problem of significance. ” During February we had advised customers on flexible contracts that this was an ideal time for making purchases. March would see prices begin to ascend again as international conflict would create problems with LNG imports, and we would highlight the geopolitical risks as an area for concern moving forwards: “ fears remain and there are potential negative catalysts that could lead to prices rising further, with the main factors to watch out for being based on geopolitical unrest. “ For a business that purchases their energy in advance, this quarter was the optimal time for purchasing during 2024. In February, electricity prices for Winter’25 were down to 7.75p/Kwh, and as low as 6.05p/Kwh for Summer’25. Winter’25 ended the year with prices above 11.1p/Kwh, with Summer’25 prices exceeding 9p/Kwh. For a company that uses 500,000Kwh of electricity per month, the difference between buying at the February low point compared to today’s prices would represent a yearly saving of over £200,000.
