For three decades, the liberalization of Europe’s electricity market has relied on 60-minute intervals for wholesale and retail electricity pricing. Existing electricity meters have also recorded consumption on this timescale.This shift to 15-minute trading reflects the need for a more granular and responsive system capable of handling the influx of intermittent renewable energy,such as solar and wind power.
Latvia’s Readiness and the Baltic States
Authorities in Latvia confirm the nation is fully prepared for the transition. This change will empower market participants to refine their production and consumption forecasts, exploiting emerging market opportunities. The move aligns with broader integration efforts within the European energy market, aiming for unified standards and enhanced trading efficiency.
The Baltic Balancing Power Market is also adopting the 15-minute trading period concurrently. This allows Baltic Power System Operators (PSOs) to more precisely plan and procure balancing capacity reserves, ensuring grid stability.
Key Benefits of 15-Minute Trading
- Improved Accuracy: More frequent trading intervals offer a more precise reflection of real-time supply and demand.
- Enhanced Flexibility: Encourages market participants to develop flexible response capabilities, unlocking economic benefits while supporting grid balance.
- Renewable Energy Integration: Better accommodates the variability of renewable energy sources.
- Increased Competition: Facilitates wider geographic market expansion and the introduction of new services.
gatis Junghans, a Board Member at JSC “Augstsprieguma tīkls” (AST), emphasized the electricity market model as a crucial tool for coordinating the power system. he noted that the increasing presence of solar, wind, batteries, and active consumers demands greater accuracy and predictability, which the 15-minute trade provides.
Impact on Market Participants
The transition requires market participants to enhance their forecasting accuracy and adapt internal IT systems to handle 15-minute data processing, trading, and accounting. Extensive system and process improvements, along with participant readiness testing, have been undertaken to ensure a smooth transition, according to nominated electricity market operators (NEOs) and PSOs.
| Feature | Previous System (60-Minute) | New System (15-Minute) |
|---|---|---|
| Trading Interval | 60 Minutes | 15 Minutes |
| Data Resolution | Hourly | Quarter-Hourly |
| Forecasting Accuracy | Lower | Higher |
| System Responsiveness | Slower | Faster |
Did You Know? The European Union is investing heavily in smart grid technologies to support this transition and further enhance energy market efficiency.
Pro Tip: Electricity traders should prioritize upgrading their systems and developing advanced forecasting models to capitalize on the opportunities presented by 15-minute trading.
The future of European Electricity Markets
The move towards 15-minute trading represents a crucial step in building a more resilient, enduring, and efficient European energy system.it aligns with the broader EU energy transition goals, which include increasing the share of renewable energy, reducing carbon emissions, and enhancing energy security. As renewable energy penetration continues to grow, further innovations in market design and grid infrastructure will be essential to unlock the full potential of a decarbonized energy future. The European Commission’s Directorate-General for Energy is continually evaluating and implementing policies to achieve these objectives.

What specific actions should large businesses with existing demand-side response programs take to prepare for the transition to 15-minute settlement?
Transition to 15-Minute Electricity Trading Begins in October for Enhanced Accounting Accuracy
What’s Changing with Electricity Settlement?
From October 2025, the UK electricity market is shifting from 30-minute to 15-minute settlement periods. This seemingly technical change has significant implications for energy suppliers, large businesses, and ultimately, consumers. The core driver? Increased accuracy in electricity trading and a more responsive grid capable of handling the influx of renewable energy sources. This move is a key component of the Ofgem’s Faster Switching Program and aims to modernize the energy system.
Why the Shift to 15-Minute Settlement?
The current 30-minute settlement period, while functional, introduces a degree of imprecision. Here’s a breakdown of the key reasons for the change:
* Improved Accuracy: Shorter settlement periods mean a more granular reflection of actual electricity usage. This reduces discrepancies between predicted and actual consumption, leading to fairer billing.
* Enhanced Grid Stability: A more responsive grid is crucial for integrating intermittent renewable energy sources like wind and solar. 15-minute settlement allows for quicker adjustments to supply and demand, preventing imbalances.
* Facilitating Smart Grid Technologies: The transition supports the rollout of smart meters and other smart grid technologies, enabling more dynamic energy management.
* Reduced System Stress: More accurate forecasting and settlement reduce the need for costly balancing actions by national Grid ESO.
* Fairer Market Participation: The change levels the playing field for all market participants, particularly those actively involved in demand-side response (DSR) and energy storage.
How Does this Affect Different Customer Types?
The impact of 15-minute settlement varies depending on your electricity consumption profile. Understanding your metering type is crucial.
* Half-Hourly Metered (HH) Customers: Primarily commercial and industrial users, these customers already have the infrastructure to handle frequent data reporting. The transition will require adjustments to their billing systems and potentially their energy management strategies. They will see more frequent and precise billing.
* Non-Half-Hourly (NHH) Customers: Typically domestic users and smaller businesses without smart meters. While not directly impacted immediately, the move to 15-minute settlement will eventually necessitate smart meter adoption for all customers to fully realize the benefits.The National Grid document https://www.nationalgrid.com/sites/default/files/documents/44939-TNUoS%2C%20BSUoS%20and%20Connection%20Charging%20Information.pdf highlights the distinction between these demand types.
* Smart Metered Customers: These customers are best positioned for the transition,as their meters already provide the necessary data granularity.
Key Changes to Expect: TNUoS, BSUoS & System Charges
the shift to 15-minute settlement will influence various charges associated with electricity supply.
* TNUoS (Transmission Network Use of System) Charges: These charges reflect the cost of transporting electricity across the high-voltage transmission network. More accurate demand forecasting enabled by 15-minute settlement can potentially optimize TNUoS charges.
* BSUoS (Balancing System Use of System) Charges: These charges cover the cost of balancing the electricity system. Reduced imbalances due to improved accuracy should lead to lower BSUoS costs.
* System Charges: Overall system charges are expected to become more reflective of actual usage, promoting fairer cost allocation.
Preparing for the Transition: A Checklist
Here’s what businesses and energy managers should do to prepare:
- Review Metering Arrangements: Confirm your metering type (HH or NHH) and ensure your systems can handle 15-minute data.
- Update Billing Systems: Ensure your billing software is compatible with the new settlement period.
- Assess Energy Management Strategies: Evaluate how the change might impact your demand-side response programs or energy storage optimization.
- Engage with Your Energy Supplier: Discuss the transition with your supplier and understand any potential changes to your contract.
- Data Validation: Implement robust data validation processes to ensure the accuracy of your consumption data.
- Consider Smart Meter Upgrade: If you are currently on a non-half-hourly tariff, explore the benefits of upgrading to a smart meter.
The Future of Electricity Trading
The move to 15-minute settlement is not a standalone event. It’s part of a broader trend towards a more dynamic, flexible, and data-driven electricity system. Expect further innovations in areas like:
* Real-Time Pricing: More frequent settlement periods pave the way for real-time pricing, allowing consumers to respond to fluctuating energy costs.
* Peer-to-peer Energy Trading: The increased granularity of data will facilitate the progress of peer-to-peer energy trading platforms.
* Virtual Power Plants (VPPs): VPPs, which aggregate distributed energy resources
