Balancing Markets 2026: aFRR, mFRR, and the New Normal

Balancing Markets 2026: aFRR, mFRR, and the New Normal
The European balancing landscape has quietly undergone one of its most consequential transformations in decades. With the full-scale rollout of cross-border platforms for automatic and manual frequency restoration reserves, the rules of the game have changed—not incrementally, but structurally.For utilities, traders, and flexibility providers, 2026 is not just another year. It marks the arrival of a new operating normal.From Fragmented to Federated: The Integration Shift
Historically, balancing markets were national, fragmented pools of flexibility with limited coordination. That model is now obsolete.

Today:The aFRR platform (PICASSO) and mFRR platform (MARI) enable pan-European optimization of balancing energy.
Most TSOs are now connected or in the process of joining, dramatically increasing liquidity and competition.
Cross-border capacity is increasingly allocated to balancing, not just day-ahead or intraday markets.This shift fulfills a core objective of European market design: shared balancing resources across borders to improve efficiency and reduce system costs.🎯 Want to stay ahead in the world of Cross-Border Power Trading & Grid Balancing?

aFRR vs mFRR: Faster, Smarter, More Competitive
Understanding the new dynamics requires revisiting the roles of aFRR and mFRR:aFRR (automatic): Activated within seconds to minutes, continuously correcting system imbalances. It operates in near real-time and is increasingly algorithm-driven.
mFRR (manual): Activated within ~15 minutes, used for sustained or larger imbalances, often through centralized optimization platforms.What’s changed is not the physics, but the market access and clearing logic:Both products are now traded across borders via common merit order lists.
Activation is increasingly driven by pan-European cost optimization, not local scarcity.Volatility: Dampened Peaks, Sharper Competition

A key expectation from integration was reduced volatility, and that is partially true.Cross-border balancing has smoothed extreme price spikes, as cheaper flexibility from neighboring systems can now be activated.
Increased liquidity has compressed spreads, particularly in aFRR energy markets.But this comes with a twist:Volatility hasn’t disappeared, it has changed shape.
Price signals are now more continuous but less forgiving.
Margins are thinner; timing and forecasting errors are penalized faster.
Local scarcity events still occur, but are rarer and more unpredictable.Costs: Efficiency Gains… with Distributional Effects
From a system perspective, integration is working:TSOs can access lower-cost balancing bids across borders, improving overall efficiency.
Increased competition is pushing down average procurement costs.However, the distribution of value is shifting:Assets that relied on local scarcity rents (e.g., legacy thermal units) face margin erosion.
Fast, flexible technologies (especially batteries) benefit from high-frequency participation in aFRR.
Geographic advantage is declining as location-based premiums compress.In short: system costs go down, but not everyone wins equally.Dispatch & Operations: Algorithmic Reality
The biggest operational shift is in dispatch logic:Activation is now driven by centralized European algorithms, not local operator discretion.
Real-time price publication (e.g., mFRR) is increasing transparency—and competitive pressure.
Imbalance pricing is directly tied to marginal balancing activations across platforms.This creates a new operational paradigm:-Forecasting accuracy becomes a core competency
-Automation and algorithmic bidding are no longer optional
-Portfolio optimization must be cross-market (DA, ID, balancing)Final Thought
The integration of aFRR and mFRR markets is doing exactly what it was designed to do: create a single, efficient balancing system for Europe.But efficiency comes at a price—the disappearance of easy profits.In the new normal, value still exists. It’s just harder, faster, and more competitive to capture.

Congestion Management Playbook: Redispatch → Countertrading

When power grids “bind,” markets don’t fail, operators intervene. Behind the scenes, system operators deploy a toolkit designed to keep markets whole while maintaining physical reliability. Two of the most critical levers: redispatch and countertrading.⚡ Why congestion happens
Electricity markets clear economically, not physically. Power flows obey physics, not contracts. When transmission constraints are hit (line limits, outages, loop flows), the system must be rebalanced in real time.Redispatch: Adjusting generation after the

Redispatch is the process of instructing generators to increase or decrease output from their scheduled positions.Generators in constrained (overloaded) areas are asked to ramp down
Generators elsewhere are asked to ramp up
The goal: relieve network stress without re-running the entire market💡 Think of it as “surgical correction”, precise, targeted, and fast.Trade-offs: Costs can rise (out-of-merit dispatch), requires transparency and fair compensation mechanisms and can distort price signals if overused.

Countertrading: Cross-border balancing

Countertrading extends the idea across bidding zones or countries.System operators buy and sell energy in different locations to relieve congestion
Often used in interconnected markets
Maintains scheduled exchanges while adjusting physical flows💡 It’s less about changing who produces, and more about where balancing occurs.Why this matters
Congestion management isn’t just an operational detail it, shapes:Market efficiency
Price formation
Investment signals (where new capacity is needed)
Cross-border cooperationAs grids decarbonize and variable renewables scale, congestion is becoming structural, not exceptional.Article content

The bigger picture
Frequent redispatch and countertrading signal a deeper issue: ➡️ Transmission constraints are lagging generation buildoutWhich raises strategic questions:Should markets shift toward nodal pricing?
How do we allocate congestion costs fairly?
What’s the right balance between market design and operator intervention?Closing thought
Redispatch and countertrading are often invisible, but they are the glue holding modern electricity markets together.Understanding them is key to understanding why “market outcomes” and “physical reality” don’t always align, and how operators bridge that gap every day.

Flow-Based vs NTC in Europe: The Capacity Shift Traders Actually Feel

What changes when Europe’s power markets become network-aware and why it matters.
If you’re entering European power markets, you’ll quickly come across two key concepts: NTC (Net Transfer Capacity) and Flow-Based. They both answer the same fundamental question:How much electricity can move between countries?But in Europe, where grids are deeply interconnected, the way this question is answered has evolved significantly. And that evolution is something traders feel every day.The European Context: Why This Matters More Here
Europe isn’t a collection of isolated markets, it’s a highly meshed system.Power flowing from France to Germany might:-Physically pass through Belgium
-Impact constraints in the Netherlands
-Affect prices across multiple countries simultaneouslyThis complexity is exactly why Europe has been moving from NTC to Flow-Based, especially in the Core region (Central Western Europe and beyond).

The Old Approach: NTC in European Markets
Under NTC, Europe treated borders like separate pipes: Each cross-border connection (e.g., France–Germany) had a fixed limit, capacities were calculated ahead of time and each border was handled independently.For traders, this meant: Clear, published limits between bidding zones, relatively straightforward spread trading and predictable constraints.But there was a catch:👉 These limits often underused the grid, because they didn’t reflect how electricity actually flows across multiple countries at once.The Shift to Flow-Based in EuropeFlow-Based was introduced to better reflect the physics of the European grid.Instead of assigning capacity border by border, it: models the entire regional network simultaneously, considers how one trade impacts flows across many lines and uses constraints on critical network elements (CNEs). In practice: There is no single “France–Germany capacity” anymore in the same way.
👉 Capacity becomes a shared, system-wide resource*

What European Traders Actually Experience
1. Capacity is no longer “per border”Under Flow-Based: You don’t just look at one interconnector, capacity depends on flows across the whole core region.👉 A trade between two countries might be limited by a constraint in a third country2. More realistic - but less intuitive - price formationBecause the grid is modeled more accurately: Price spreads reflect real congestion patterns, loop flows and parallel paths are implicitly accounted for👉 Prices can move in ways that feel surprising if you’re used to NTC logic.3. Non-linear and sometimes counterintuitive outcomesIn Flow-Based: Increasing demand in one zone can reduce capacity elsewhere, a trade that “should work” under NTC may not clear.👉 Traders often encounter outcomes that require deeper system understanding4. New opportunities - but also new risksThe upside: Better utilization of cross-border capacity, Occasional hidden capacity unlocked by the systemThe challenge: Harder to forecast available capacity, greater reliance on data, tools, and experience.Why Europe Made the Shift
The move to Flow-Based is driven by three main goals: use the grid closer to its real limits, strengthen the single european electricity market and better reflect physical realities, even if complexity increases initiall.In Europe, the transition from NTC to Flow-Based changes how traders think:Before: Focus on bilateral spreads, trade specific borders.Now: Think in terms of zones within a network, understand how constraints propagate across countries.

Final Thoughts
Flow-Based is not just a technical upgrade, it’s a structural shift in how Europe allocates capacity. It can feel less predictable at first, especially if you’re used to clear border limits. But over time, it provides a more accurate picture of how electricity actually flows across the continent.In Europe, NTC simplified reality. Flow-Based embraces it. For anyone entering the market, understanding this shift is key to making sense of prices, risks, and opportunities.

One Grid, Many Markets: How Market Coupling Aligns Power Prices

From Day-Ahead to Intraday: What Actually Drives Cross-Border Flows
Why Do Power Prices Differ Across Borders?
Even in interconnected regions, electricity prices don’t always match. Why? Because without coordination:One region may have surplus (low prices)
Another may face shortage (high prices)
And limited transmission prevents balancingThis leads to inefficiencies—cheap power stays unused while expensive power is still produced elsewhere. Market coupling exists to fix exactly this problem.What is Market Coupling (In Plain Terms)?
Market coupling connects electricity markets so they clear together instead of separately. Instead of each region deciding prices on its own, it becomes one coordinated outcome across regionsThe system simultaneously decides:Who generates electricity
Where it flows
What price each region seesAll while respecting grid limits.

The Core Idea (No Math Needed)
At its simplest, market coupling ensures: Electricity flows from where it’s cheapest → to where it’s needed most. When this happens: costs go down, prices start aligning and cross-border capacity is used efficiently.

Day-Ahead Market Coupling: Participants submit bids for the next day, a central algorithm clears all regions together and prices and flows are determined in one go.What you see: Power flows from low-price to high-price regions and prices converge when capacity allows. If transmission is limited, prices still differ, but less than before.Intraday Market Coupling: Reality doesn’t follow forecasts. Things change: Wind drops, demand spikes and plants trip. That’s where intraday comes in. It enables continuous cross-border trading, lets participants adjust closer to real time and uses any remaining transmission capacity.Why it matters: Reduces imbalances, avoids expensive last-minute fixes and adds flexibility to the system.What’s Really Being Coordinated?
Across both markets, three things move together:1. Prices: Reflect real-time supply-demand conditions2. Flows: Electricity moves across borders3. Capacity: Transmission limits are respectedThis coordination is what turns separate markets into one system.What Happens Without Coupling?

Think of three scenarios:No coupling → Large price differences, inefficiency
Partial coupling (limited capacity) → Some convergence
Strong coupling (enough capacity) → Prices align, flows optimizeThat middle case is where most real-world systems operate today.Final Take
Market coupling is not about complexity, it’s about coordination at scale.It ensures: Power flows where it creates the most value, prices reflect system-wide realities and cross-border infrastructure is fully utilized.In short: Coupled markets are more efficient, more resilient, and better suited for a renewable-heavy future.

Grid Is the Real Bottleneck in Energy Transition

For years, the biggest challenge in the energy transition was building enough renewable energy capacity. Today, that problem is rapidly disappearing.Solar and wind are now the cheapest sources of electricity in many regions, and investment in renewable projects continues to accelerate. Yet across the world, thousands of clean energy projects remain stuck in queues, curtailed, or delayed. The reason is increasingly clear.The grid cannot keep up. Transmission infrastructure, the backbone of the power system, has become one of the biggest bottlenecks in the global energy transition.The Growing Mismatch Between Generation and Grid Capacity
Renewable energy projects are often built where resources are strongest, not where electricity demand is highest.Solar farms are built in sunny deserts and open land.
Wind farms are located offshore or in windy rural areas.But electricity demand tends to be concentrated in urban and industrial centers. This creates a fundamental challenge: electricity must travel hundreds or even thousands of kilometers to reach consumers. Without sufficient transmission capacity, even the most efficient renewable projects cannot deliver their power to the grid.

Transmission Congestion: When the Grid Gets Full
One of the clearest signs of grid bottlenecks is transmission congestion. Congestion occurs when electricity flows reach the maximum capacity of transmission lines. When this happens, grid operators must limit generation to maintain system stability.The result?Renewable plants are forced to reduce output
Electricity prices can spike or collapse depending on location
Clean energy gets curtailed despite strong demandIn some regions, congestion is already causing billions of dollars in lost renewable energy every year.

Renewable Curtailment: Clean Energy That Never Gets Used
Curtailment refers to situations where renewable power plants are instructed to shut down or reduce generation, even when wind or solar resources are available.This usually happens when: the grid cannot transport the electricity, supply exceeds local demand, or system stability must be maintained.While curtailment is sometimes necessary, rising levels indicate structural grid limitations. Ironically, this means that clean electricity is being wasted while fossil plants continue operating elsewhere in the system.The Interconnection Queue Problem
Another major bottleneck lies in the interconnection process — the procedure that allows new power plants to connect to the grid. In many electricity markets, the number of proposed renewable projects has grown dramatically.However, grid operators must study each project to ensure it does not compromise system reliability. This has created massive queues. In some regions:thousands of gigawatts of projects are waiting for approval
developers face years-long delays before construction can begin
many projects ultimately withdraw due to uncertainty and costsIn other words, the energy transition is increasingly limited not by technology or investment but by administrative and infrastructure constraintsPossible Solutions

Addressing the grid bottleneck will require a combination of strategies:1. Accelerated transmission investment Large-scale grid expansion and modernization will be necessary.2. Grid-enhancing technologies Dynamic line ratings, advanced conductors, and digital monitoring can increase capacity on existing lines.3. Energy storage deployment Battery storage can absorb excess generation and release it during peak demand.4. Smarter market design Better price signals can incentivize generation where the grid has capacity.**5. Faster permitting processes **Regulatory reform could significantly reduce project timelines.The Next Phase of the Energy Transition
The first phase of the clean energy transition was about making renewable power cheap. That phase has largely succeeded.The next phase is about moving electricity efficiently across the system. And that challenge will define the next decade of energy infrastructure investment. Because increasingly, the future of clean energy depends not just on how much power we generate but on how effectively we move it.

⚡ Why Cross-Border Power Prices Diverge

What price spreads really tell us about Europe’s power markets in 2026
Europe’s electricity market was designed for convergence. But in 2026, price divergence across borders is not the exception — it’s the signal. For traders, this isn’t inefficiency. It’s opportunity, if you understand what’s driving it.📊 The Reality: One Market, Multiple Prices
Despite market coupling, day-ahead and intraday prices across Europe continue to separate — sometimes sharply.Germany vs France. Nordics vs Baltics. Italy vs Central Europe. These spreads are not random. They are structural.⚙️ What’s Driving Cross-Border Price Divergence?
Let’s break down the four core drivers shaping spreads today:1. Grid Congestion Is the New Price Maker
Transmission constraints are increasingly defining price zones.Limited interconnector capacity restricts arbitrage
Internal grid bottlenecks (e.g. north-south Germany) distort flows
Renewable generation is often stranded from demand centers👉 Result: Prices decouple even when fundamentals suggest convergence

2. Scarcity Pricing Is Becoming More Localized
As dispatchable capacity tightens, scarcity is no longer system-wide — it’s regional.Gas availability differs by country
Nuclear outages (e.g. France) create localized spikes
Hydro conditions reshape Nordic pricing dynamics👉 Result: Local supply-demand imbalances drive sharper spreads3. Balancing Risk Is Now a Trading Variable
Balancing markets are no longer a back-end correction — they’re part of the strategy.Renewable intermittency increases imbalance exposure
Forecasting errors create intraday volatility
Balancing costs differ significantly across TSOs👉 Result: Traders price in imbalance risk — widening cross-border spreads4. Policy Fragmentation Is Rewriting Market Signals
Europe’s energy transition is not uniform.Different subsidy schemes (CfDs, capacity markets)
National interventions during crises
Carbon pricing pass-through variations👉 Result: Structural divergence in how prices are formed📉 From Convergence to Volatility: A Structural Shift
The old assumption: ➡️ Interconnection = price convergenceThe new reality: ➡️ Interconnection + constraints = tradable volatilityCross-border spreads are now a function of:Physical infrastructure limits
Renewable penetration
Market design differences
Real-time system stress🎯 What This Means for Traders
To stay competitive in 2026, trading strategies must evolve:✔️ Move beyond zonal price assumptions ✔️ Integrate congestion forecasting into models ✔️ Co-optimize across day-ahead, intraday, and balancing markets ✔️ Track policy and regulatory signals as closely as fundamentalsThe edge is no longer just price prediction — It’s understanding why prices diverge.

🔍 Final Thought
Cross-border price divergence is not a flaw in Europe’s market design. It’s a reflection of a system under transformation.And for those who can decode it — It’s one of the most valuable signals in today’s power markets.
