2025 Yearly Review

12 January 2026

In a year where news coverage was dominated by Israel’s genocide in Gaza and the on-going conflict between Russia and Ukraine, geopolitical events played a key role in dictating the movements of the energy markets. In this article we take a look back at 2025, revisiting the stories that impacted energy prices, and look at what is likely to shape the gas and electricity markets in 2026.

The year started with the UK recording its coldest temperature in 15 years and gas prices rising in the wake of Russian gas ceasing to flow into continental Europe. News of the US lifting their LNG export ban offered some respite, but prices failed to drop in the first month of the year after they had risen sharply in the final few months of 2024.


In February, milder-than-expected weather combined with the commencement of peace talks between Ukraine and Russia brough some optimism to the markets. This saw prices for Summer’25 gas and electricity drop by approximately 15%.


Prices continued to decline in March, although the EU issuing mandated gas reserve levels meant there would be an increased buying pressure which would keep prices propped up for the coming months.


Q2


The trend of wholesale energy prices falling continued into April, where prices for Summer’26 gas fell by almost 15%.

This April price drop was largely due to unseasonably warm weather domestically, and the US imposing tariffs that caused production cuts which led to lower energy consumption internationally.

This meant that for a business set to consume 100,000 therms (2,930,713 kWh) during April-September of 2026, if they had purchased their gas for this period at the end of April, they would have saved approximately £20,000 compared to the prices at the start of January.

At this time, we acknowledged in our monthly review for April that:


 “the market is still volatile, and tariffs being repealed or increased conflict in Ukraine could lead to prices rising again.”


This was shown to be prescient as increased tensions between Ukraine and Russia, maintenance of Norwegian gas fields, and the potential of conflict between Israel and Iran caused prices to rise in May.

When we then stated that:


 “it seems as though multiple catalysts are in place that could drive prices up in the coming months... it seems that even further progress in Russian/Ukrainian peace talks may not be enough to cause another significant drop in prices…the market will likely react more sharply to any negative news impacting these supply chains.”


This proved to be the case as prices rose in June due to international conflicts threatening to disrupt global supply routes. Wholesale markets rose by 25% during the month, before news of a cease fire helped prices return to previous levels.


Q3


Prices remained volatile in July as fears increased about whether EU gas reserve goals would be met, however, prices began to fall again in August when data showed that most nations were set to hit their targets.

At the end of August, we wrote:



“ it appears that restrictions to supply from Russia will have a muted effect compared to 3 years ago. While this caps the potential for price rises, the possibility of Russian pipelines being re-opened to European markets still has the potential to lower prices.”


The markets would continue trading in a flat range throughout September, with little change in prices being observed. At this time – with the mandated buying coming to an end – it became clear that prices looked set to drop, and we stated as much in our September review:

 

“With European buying pressure dropping off and there being no clear, imminent threats to supply, it seems as though prices could be set to drop over the coming months.”


This would come to fruition in the final quarter of the year, when wholesale prices dropped significantly. Although, despite these drops in price, rising standing charges would mean few businesses would see the benefit of this decline.


Q4


After a relatively uneventful October, prices began to fall during November, with wholesale gas prices reaching their lowest levels since July’24. After a budget that offered little relief to UK businesses hoping for assistance with their energy costs, further news of peace-talks between Russia and Ukraine did however offer some hope, as prices dropped on the back of this news.

With the European state buying pressure now removed, prices were able to hit their yearly lows as we entered December. Prices then continued to drop in the first week of the month before stabilising slightly as forecasts emerged of colder-than-expected weather for the end of December and early part of January.


At the end of December, it was confirmed that TUoS and DUoS prices would be set to significantly increase in April. For some businesses these can be charged as individual line items, but for others it will be added via their standing charge.


For the business looking to buy 100,000 therms of energy for Summer’26, the difference between the yearly high in February, and the low in December, equates to a difference of over £45,000. Further highlighting the importance of when to time your energy purchases.

For this period, gas prices had dropped over 30%, however, electricity prices had dropped by less than 5%. Historically there had been a stronger correlation between gas and electricity prices but this correlation seems to have been weakened by the percentage of the UK’s electricity now generated by renewables. This high volume of renewable generation has long-term positives but has also been largely responsible for the rise in non-commodity costs. The amount of work and investment necessary to update the existing grid infrastructure is the primary driver behind standing charges rising so significantly in recent years.


2026 Outlook

In the early part of the year, weather is set to be a key driver behind prices. Forecasts are suggesting that there will be an increased risk of storms and colder than usual weather up until the 20th of January, but after this we should see milder conditions. For those looking to renew contracts or make energy purchases in the early part of the year, February looks likely to be the sweet spot between poor weather conditions and European nations once again looking to replenish their gas reserves.


With the Suez Canal set to reopen, this offers increased shipping options and could lower transport costs, but any further military action in the Middle East would likely send prices higher.


Any peace deal between Russia and Ukraine that would allow for Russian gas flowing back into Europe would send prices lower, but this doesn’t seem likely to happen in the immediate future.


LNG exports are expected to increase with the US and Qatar both adding to their export capacity. Norway is also expected to increase their gas exports from 2025, meaning the supply side of the picture is looking healthy for the UK.


On the demand side, Chinese demand is expected to increase following a muted 2025--  as a result of US tariffs being imposed -- however, it seems likely they may be a major purchaser of energy from Russia and not necessarily in direct buying competition with European nations. They also have well-stocked coal supplies and don’t adhere to the same environmental guidelines as most European nations.

In summary, without geopolitics yet again having a strong influence on the markets, gas and electricity could see one of the most stable years in recent memory, with a slight decline expected. However, dismissing the possibility of geopolitical factors dominating the energy landscape seems overly optimistic, and constant adaptations to ever-changing global conditions will once again be a necessity.

It should also be noted that any drops in wholesale energy prices may be negated by the rising non-commodity costs and standing charges. From the 1st April, the new TUoS and DUoS rates will take affect, further increasing the energy costs for UK businesses, most notably for high-volume consumers.

Where Does My Energy Come From?

24 February 2026
Where Does My Energy Come From? It’s a simple question, but the answer is more complex than many businesses realise. When you flick a switch or power up your operations, the electricity and gas you use is the end product of a vast, interconnected system of generation, infrastructure, global markets and regulation. Understanding where your energy comes from isn’t just a curiosity, it’s commercially relevant. Electricity: A Real-Time Balancing Act In the UK, electricity is generated from a mix of sources. The primary contributors today include: Gas-fired power stations Wind (onshore and offshore) Nuclear Solar Interconnectors importing power from Europe Unlike gas, electricity must be generated and consumed in real time. Supply and demand are constantly balanced by the system operator, ensuring the grid remains stable. If supply ever falls short, then prices can spike. In recent years, numerous grid updates have taken place to ensure that renewable energy can be added to the grid and quickly transported. While many businesses purchase “renewable” tariffs, this doesn’t mean the electricity you receive was generated by renewable sources. Electricity on the grid is pooled, so you don’t receive electrons directly from a specific wind farm. Instead, suppliers match your usage with renewable generation certificates (REGOs), demonstrating that an equivalent amount of green power has been produced. For larger energy users, the mix of generation matters because it directly impacts wholesale pricing. An evening with low wind output, for example, can significantly increase reliance on gas-fired generation, therefore increasing exposure to the wholesale price of gas. Gas: A Global Commodity Gas plays two roles in the UK energy system: Heating homes and businesses directly, and fuelling many power stations that generate electricity. The UK produces some natural gas domestically from the North Sea, but production has declined over the years. Today, a significant proportion of supply is imported via: Pipelines from Norway Liquefied Natural Gas (LNG) shipments – particularly from Qatar and the US Interconnectors from continental Europe Because gas is traded globally, UK prices are influenced by international supply and demand dynamics. Events in Europe, Asia or the US can directly affect what UK businesses pay. This means geopolitical events such as the threat of war in the Middle East can cause prices to rise sharply . Renewables and the Energy Transition The UK’s generation mix has changed dramatically over the past decade. Coal has been phased out, while wind and solar capacity have grown significantly. This shift brings both opportunity and volatility. Renewable generation lowers carbon intensity and reduces exposure to fuel imports. However, because wind and solar output depend on weather conditions, short-term price fluctuations have become more pronounced. For businesses with flexible procurement strategies , understanding this dynamic can create opportunities to secure more competitive pricing. Why It Matters for Your Procurement Strategy Where your energy comes from can influence many other aspects of your energy strategy, including: Wholesale market pricing Carbon reporting obligations Contract structures Long-term risk exposure Understanding where your energy comes from has never been more important for UK businesses. If you want to understand how the current generation mix and global gas markets are affecting your upcoming renewals, SeeMore Energy can help you interpret the landscape and see what options are currently available for you.

How Do I Find Out Who Is My Energy Supplier?

23 February 2026
How Do I Find Out Who My Energy Supplier Is? This is a surprisingly common question, particularly if you’ve just moved into a new property, taken over an existing site, or inherited responsibility for energy procurement.  If you don’t know who supplies your electricity or gas, don’t worry. There are clear steps you can take to find out quickly and avoid unnecessary delays, billing issues, or out-of-contract rates. 1. Check Recent Bills or Tenancy Documents If the property has been occupied recently, the simplest place to start is with a previous energy bill. This will confirm: The supplier name Your account number The supply address Your MPAN (electricity) or MPRN (gas) If you’ve just moved in, your landlord, managing agent, or outgoing tenant may also be able to confirm the supplier. 2. Use the National Databases If no bills are available, you can use the industry’s central databases. For electricity , contact your local Distribution Network Operator (DNO). In England, Scotland and Wales, you can find your DNO via the Energy Networks Association website . They can confirm your current electricity supplier and provide your MPAN. For gas , you can contact the Meter Point Administration Service (MPAS) via the Xoserve database, or use the find my supplier tool. These services are free and typically provide confirmation immediately. 3. Contact the Meter Operator In some cases, particularly with larger commercial sites, your appointed meter operator may be able to confirm the registered supplier. This is more common where contracts have been arranged historically through brokers or third parties. Common meter operators include IMServ, Npower, and Stark. 4. Act Quickly to Avoid Out-of-Contract Rates If you’ve taken over a site and haven’t agreed a contract, you could be placed on deemed or out-of-contract rates . These are usually significantly higher than negotiated market rates. Confirming your supplier allows you to: Request historic consumption data Understand your current contract status Avoid unexpected charges Begin procurement discussions Why It Matters Knowing your supplier isn’t just administrative, it’s commercially important. Without clarity on who supplies your energy, you can’t properly review your costs, assess renewal timing, or manage market exposure. If you’re unsure where to start, or if you’ve identified your supplier but don’t know what contract you’re on, SeeMore Energy can help you interpret the position and plan your next steps with confidence. Getting clarity is the first step towards controlling your energy strategy.

The Capacity Market: An untapped revenue source

18 February 2026
The Capacity Market: An untapped revenue source With wholesale markets volatile and network costs rising, many businesses are looking at strategies to reduce energy spend. In addition to lowering costs, there are ways that large consumers of energy can monetise their existing energy set up. By selling back unused capacity via the Capacity Market (CM), businesses can generate tens of thousands of pounds each year, without having to make any material changes to how they run their operations. What is the Capacity Market? The UK Capacity Market was introduced in 2014 to safeguard security of supply. The CM has two main objectives: Incentivise new sources of generation that can prevent issues on the demand-side. Provide a last-resort mechanism to prevent electricity shortages during times of system stress. Administered by National Energy System Operator (NESO), the scheme pays providers for being available to deliver capacity during periods of system tightness. Businesses can receive payments, not for generating electricity, but for committing to reduce demand or increase supply if required. Capacity is secured through annual auctions (one year ahead and four years ahead), which set a £/kW price. Once contracted, participants receive an availability payment in return for meeting testing requirements and being ready to respond to a system stress event. Since the CM’s inception, there has never been a full system stress event triggered. Although precautionary notices have been issued and subsequently stood down – normally within 2 hours of being issued. How Can Businesses Make Money from It? For many businesses, the opportunity lies in Demand Side Response (DSR) . If a business can demonstrate that it is capable of reducing load during a stress event -- even for just 30 minutes -- that reduction can be contracted into the Capacity Market. The process for this is: Historical half-hourly data is analysed to establish normal usage. Periods where usage dropped materially (e.g. shutdowns, maintenance, early finishes, seasonal dips) are identified. The difference between normal usage and the reduced period becomes the site’s deliverable capacity. This capacity is aggregated with other businesses into a CM Unit (CMU) and entered into the auction. Payments are then made quarterly in arrears for being available.

The Importance of Forecasting Annual Usage Before Procurement

12 February 2026
Forecasting annual electricity and gas consumption is one of the most important -- and often underestimated -- stages of the procurement process. While timing the wholesale market and contract structure typically receive the most attention, the accuracy of the consumption forecast can have a large influence on overall energy costs. Suppliers price risk based on expected volumes, network charges are dictated by usage patterns, and internal budgets depend on accurate projections. Without a reliable forecast, organisations expose themselves to avoidable financial and contractual risk. How Consumption Forecasting Works Forecasting begins by analysing historical usage. Half-hourly electricity data, meter reads, and seasonal profiles provide a baseline that shows how a site behaves over time. This historical data is then adjusted to account for known changes, such as production increases, machinery upgrades, operational reductions, or energy efficiency projects. For larger or more complex organisations, forecasting may involve modelling peak demand, load shape, and expected operational shifts across multiple sites. The aim is not simply to estimate an annual total, but to understand when and how energy will be consumed throughout the year. That detail becomes particularly important when selecting contract structures or assessing exposure to network charges. How It Impacts Budgeting Energy often represents a significant operational cost, particularly for manufacturers and other energy-intensive users. Accurate forecasting enables finance teams to build realistic budgets and avoid the shocks of unexpected costs. Reliable forecasts also allow organisations to model different pricing scenarios. Understanding likely consumption enables comparison between fixed contracts and flexible purchasing strategies . It also supports long-term planning by quantifying the financial impact of operational changes or sustainability initiatives.

Are your energy invoices in the correct company name?

5 February 2026
Why it’s important your energy bills are in the correct company name For many businesses, energy bills aren’t reviewed with a high-level of scrutiny. As long as the meter is live and the lights stay on, the paperwork often goes unquestioned. However, having electricity and gas bills issued in the correct legal company name is more important than many organisations realise. Failing to ensure that your invoice is correctly addressed can create unnecessary risk and cost. How it can impact your business Energy contracts are signed with a specific legal entity, not a trading name or group brand. If the company name on the bill does not match the Companies House records, the contract may not accurately reflect who is legally responsible for the supply. This can cause problems in the event of disputes with the supplier, changes of tenancy or site ownership, and contract renewal or termination. In some extreme cases, suppliers can refuse to amend or even enforce contracts where the named party is incorrect. Affecting credit checks and pricing Suppliers assess risk using the company name registered on the account. If this is incorrect or outdated: Credit checks may fail or be delayed Higher security deposits may be requested Less competitive pricing may be offered For growing businesses, group structures or recently incorporated entities, this can result in paying more than necessary for energy, simply because the account information isn’t aligned. Delaying contract changes and site updates Something as simple as renewing a contract, adding meters, or updating a supply address can become complicated if the company name is wrong. Common scenarios include: Sites transferred between group companies Trading names used instead of legal names Businesses that have changed structure or ownership Each of these can trigger lengthy data disputes between suppliers, distributors and settlement systems, often delaying changes by weeks or months. Issues with VAT, levies, and exemptions Where VAT exemptions exist, the name on the invoice is required to match the name of the business that has the exemption. There are numerous government schemes that offer businesses relief from specific environmental levies and non-commodity charges . Many of these schemes – such as the British Industry Supercharger – are applied to companies with eligible SIC codes. If the business name is incorrect, then the SIC code cannot be verified and the business may end up missing out on the exemption. Future Contracts When tendering energy contracts, suppliers rely on accurate account data. Incorrect company names can slow down the quoting process, result in quotes being withdrawn, or lead to errors in contracts or start dates. For businesses managing multiple sites, this becomes even more critical. How we help businesses get it right As an energy broker, we regularly see cost and risk created by something as simple as incorrect account information. We help businesses:  Verify company names against Companies House Correct supplier and industry records Manage name changes during restructures or acquisitions If your business requires help with ensuring that your invoices are being issued in the correct name, contact us today and one of our experienced team can assist with all of your energy needs.

Rising non-commodity costs

5 February 2026
Rising TNUoS and DUOS charges By Adam Novakovic T.S Eliot once said that “April is the cruellest month” and in terms of the prices many businesses pay for their electricity, his quote is prophetically true. While he may not have envisioned rising TNUoS and DUoS costs being the reason for the starkness of the month, for many British businesses, the rise in non-commodity charges that take effect from April 1 st will add unwanted and unneeded extra costs to their energy bills. From the beginning of April, businesses across the UK will see significant increases in two major components of their energy bills: Distribution Use of System (DUoS) and Transmission Network Use of System (TNUoS) charges. These network charges are becoming an increasingly large part of business energy bills -- especially for companies that operate in energy-intensive industries. DUoS & TNUoS, and Why They Matter Both DUoS and TNUoS are network charges applied to electricity bills. As non-commodity charges, they are not related to the cost of energy itself: DUoS charges cover the cost of running, maintaining and reinforcing local distribution networks that carry power to sites. They are paid as a standing charge (in p/day), a capacity charge (in p/kVA/month), and in red/amber/green unit rates – depending on the time of consumption. TNUoS charges fund the high-voltage transmission network operated nationally. This is applied as a standing charge (in p/day). For many businesses, these line items are already making up over a third of their total electricity costs . How these charges change from April 1 st 2026 TNUoS The TNUoS rate that businesses pay is set by NESO (National Energy System Operator). How much a meter is charged per day is dependant on the assigned TCR band . For sites with lower expected consumption, they will be grouped in a lower band, whereas the largest consumers will be in the higher bands and they will be charged more.

January Review 2026

1 February 2026
By Adam Novakovic January began with a sense of optimism. The new year brought hopes that energy prices could soon return to levels not seen since 2021, wholesale prices were falling and large quantities of new LNG were scheduled to be available for import during 2026. However, events that transpired during the first 31 days of the year have caused prices to rise and have sent waves of fear throughout the energy markets. The month began with a wave of cold weather leading to above-expected gas consumption. An Arctic blast combined with Storm Goretti brought temperatures down to below -10°C and led to gas power stations being needed to make up the shortfall, causing an uptick in wholesale gas prices.

Understanding Weighted Average Price (WAP) in energy

30 January 2026
What is the Weighted Average Price (WAP) in energy? In the UK energy market, Weighted Average Price (WAP) refers to the average price paid for electricity or gas over a period of time, weighted by the volume bought at each price point. For those on flexible energy contract, the WAP represents what the unit rate will be when multiple purchases were made for the same period. In other words, it answers the question: “What did we actually pay for our energy once all purchases and volumes are taken into account?” This makes WAP far more meaningful than a simple average, especially in volatile markets. How WAP works in practice Energy prices move constantly. Businesses, particularly those on: Flexible contracts Basket or portfolio products Pass-through arrangements often buy energy in multiple tranches at different times and prices. For example: 40% of energy bought at 10.0p/kWh 30% bought at 12.0p/kWh 30% bought at 9.0p/kWh The WAP reflects the price-weighted impact of each purchase, giving a single unit rate that reflectsthe real cost exposure. Why WAP matters to UK businesses 1. It reflects real procurement performance WAP shows how effective your buying strategy has been, not just whether the market went up or down, but how your timing and volumes performed. 2. It’s essential for budgeting and forecasting Using WAP allows businesses to: Accurately forecast energy spend Compare performance year-on-year Avoid misleading headline prices This is especially important for manufacturers and high-consumption sites where small price differences materially impact costs. WAP vs fixed prices Fixed contracts : WAP is locked in at the point of contract Flexible contracts : WAP evolves over time as more volume is bought This means WAP can improve with smart market timing and deteriorate if exposure is unmanaged. For those on fixed contracts, it can be vital that portfolios are being managed by a person or group with experience and expertise in energy markets. Ultimately, the strategy of when and how much to buy is just as important as the market itself. WAP as part of your purchasing strategy Weighted Average Price is the truest reflection of what your business actually pays for energy. Understanding it is critical to controlling cost risk in volatile markets. For larger SMEs and energy-intensive businesses, having a clear energy purchase strategy and having this strategy communicated through regular reporting can be vital for forecasting future energy costs.

Meter types explained: LV, HV, and EHV

29 January 2026
Meter types explained (LV, HV and EHV) For many businesses, electricity is treated as a fixed overhead -- something that cannot be changed. But in reality, how your site is connected to the electricity network can significantly influence what you pay , and many organisations are unknowingly on a setup that no longer suits their operations. Whether your supply is Low Voltage (LV), High Voltage (HV) or Extra High Voltage (EHV) impacts network charges, flexibility, and future growth. Understanding the difference could be the key to reducing costs and avoiding any unpleasant surprises. Low Voltage (LV): common, simple — and often overlooked Low Voltage (LV) supplies electricity at up to 1,000 volts and is the most common connection type for SMEs, offices, and retail units. LV customers usually benefit from: Straightforward billing Lower DUOS standing charges Minimal technical involvement However, simplicity can mask inefficiency. As businesses grow, extend operating hours or add energy-intensive equipment, LV sites can find themselves paying disproportionately higher network charges as red and amber unit charges make up a higher percentage of the costs. If your electricity costs have risen faster than your usage, your meter type could be part of the reason. High Voltage (HV): complexity that creates opportunity High Voltage (HV) connections operate between 1,000 and 22,000 volts and are typically used by manufacturers, large warehouses and energy-intensive commercial sites. HV supplies bring: Higher capacity charges Greater exposure to kVA related costs More detailed half-hourly consumption data While this can appear daunting, it also creates opportunity. Businesses that understand how and when they use electricity can actively influence costs, often achieving savings that are simply unavailable at LV. Many HV customers pay for more capacity than they need --or the wrong capacity altogether -- without realising it. Contact us today and we can conduct a kVA review that could potentially save £10,000s annually. Extra High Voltage (EHV): where energy becomes strategic Extra High Voltage (EHV) applies to supplies above 22,000 volts and is reserved for the UK’s largest electricity users. At EHV level: Network charges are highly bespoke Costs are closely linked to site-specific infrastructure Small demand changes can have large financial impacts For these businesses, electricity is not just a utility, it’s a strategic cost driver that requires ongoing oversight. Without regular review and proactive management, EHV sites can sleepwalk into avoidable six-figure cost increases. Why understanding meter type matters Meter type determines: How DUoS and other network charges are applied How much control you have over peak costs Whether your connection aligns with how your site actually operates today Many businesses inherit their meter type and never question it, even when their operations change dramatically. These changes in how a meter operates can require reviews of kVA capacities, meter type, and TCR bands . All of which can help towards reducing energy spend. How we help businesses take control As an energy broker, our role goes far beyond securing competitive unit rates. We help businesses: Understand whether their current meter type still fits Identify inefficiencies hidden within network charges Plan energy strategies that support growth, not restrict it If you’d like to understand whether your LV, HV or EHV supply is working for your business, or quietly working against it, a no-obligation review could uncover meaningful savings and future-proof your energy strategy.

Balancing Services Use of System (BSUoS) charges

28 January 2026
What are Balancing Services Use of System (BSUoS) charges? Balancing Services Use of System ( BSUoS ) charges recover the cost of keeping the electricity system in balance in real time. Electricity must be generated and consumed at the same moment, and BSUoS funds the actions National Grid Electricity System Operator (NESO) takes to achieve this. These actions include: Instructing generators to increase or decrease output Paying for reserve and response services Managing system constraints and frequency control BSUoS is therefore not about building networks (like TNUoS or DUoS ), but about operating the system safely and securely second-by-second. Who pays BSUoS charges? Since April 2023, BSUoS costs have been recovered entirely from electricity demand rather than split between generators and suppliers. In practice: Suppliers pay BSUoS charges to the system operator These costs are then passed through to all electricity consumers, including business customers Most businesses see BSUoS as a pass-through charge in their supply contracts Domestic customers also contribute, although the charge is typically embedded rather than itemised. How do BSUoS charges work in practice? BSUoS is charged on a per kWh basis, based on actual electricity consumption during each settlement period. The BSUoS rate reflects the real-time cost of balancing the system, which can vary significantly depending on: Weather conditions Generator availability Network constraints Levels of intermittent renewable generation Unlike DUoS or TNUoS, BSUoS is not location-specific. The same rate applies across Great Britain for each settlement period. How much is BSUoS (and when are charges set)? BSUoS charges are not fixed in advance. Instead, they are calculated using a forecast-and-reconciliation model. This means the amount originally charged can be reconciled after the fact once actual consumption data is available. In p/kWh terms, BSUoS charges have varied widely in recent years, but for business customers they have typically fallen in the range of 0.6–1.6 p/kWh, with occasional spikes during periods of market volatility. Because of this variability, BSUoS can be a driver of bill uncertainty for large and flexible users. Why BSUoS matters for businesses As the electricity system becomes more reliant on intermittent renewables, balancing actions are expected to increase. This means BSUoS is likely to remain a material and structurally important cost. For sites with half-hourly metering, reducing consumption during system stress periods -- or using on-site generation and storage -- can help limit exposure, although BSUoS is generally less controllable than DUoS or TNUoS. If you would like to ensure that your BSUoS charges are being invoiced correctly. Contact us today and we can review your recent invoices to make sure you aren't paying more than necessary.
