5 Still fully real

Introduction

In November 2024, I published an article on the top 16 digital challenges of Europe’s electricity market reform.

Twenty months later, every one of those 16 challenges remains real. None has disappeared. But the tools available to tackle them have changed dramatically. AI has moved from a buzzword to a production reality in the energy sector: Machine learning-based renewable generation[1] and price[2] forecasting has become standard, and generative AI is entering compliance and contract management[3].

This companion piece revisits all 16 challenges through the AI lens. For each, I ask: Is the challenge still the same? Has AI changed the solution — or the problem itself?

The verdict: AI has fundamentally transformed the solution for 5 of the 16 challenges, accelerated the approach for 6, and left 5 essentially unchanged. The pattern is clear — AI excels where the bottleneck is data processing, forecasting, or real-time optimisation. It remains largely irrelevant where the bottleneck is regulatory fragmentation, political coordination, or physical infrastructure.

I. Short-term markets

Challenge 1: Reduced cross-zonal gate closure times

AI-transformed

The regulatory mandate has now taken effect: since 1 January 2026, intraday cross-zonal gate closure times must be no more than 30 minutes ahead of real time[4] – halving the time between bidding and dispatch. The shorter window is already live on many borders, with time-limited derogations on the rest.[5]

Quite many transmission system operators still need speedier scheduling; traders need to improve real-time position management in some countries.

Challenge 2: Dynamic pricing

AI-transformed

Legally dynamic pricing is a done deal. Germany has transposed EU law in § 41a(2) German Energy Industry Act (EnWG). All electricity suppliers in Germany are legally required to offer at least one dynamic tariff option to their customers.

The commercial reality is different. 2024 only 7% used a dynamic power tariff in Germany. Dynamic prices are not understood[6], or hidden[7]. Power price comparison portals show dynamic tariffs in a way to compare them against fixed tariffs and do not offer a sensible comparison of dynamic tariffs as such.

Technically energy suppliers need to handle up to 8,760 line items per customer per year for dynamic hourly pricing, 35,040 for quarter-hourly pricing. In 2026, this is technically a solved problem. Cloud-based Meter Data Management platforms – e.g. Itron’s cloud-hosted IEE MDM[8], Siemens’ Gridscale X (formerly EnergyIP MDM SaaS)[9] – have substantially reduced data processing latency and can handle real-time data validation at scale.

AI has shifted the challenge from “can we handle the data?” to “can we extract value from it?” Machine learning now enables personalised consumption recommendations, anomaly detection, and predictive billing that can turn dynamic pricing from an operational burden into a competitive differentiator.

Suppliers who invested early in dynamic pricing are already far ahead. Those who treated dynamic pricing as purely a billing problem are falling behind.

Challenge 3: Smart meter rollout

Still fully real

Smart meter penetration across the EU remains wildly uneven. Germany, at roughly 5.5 % at the end of 2025, has made progress but still lags far behind the rest of Europe[10].

AI cannot install physical hardware.

Where AI does help is in extracting more value from fewer meters. AI-powered analytics can predict demand patterns, and forecast generation from sparser data than traditional statistical methods required. This means that even partial smart meter coverage becomes more useful — but it is not a substitute for actual rollout. The smart meter gap in Germany remains a real constraint.

Challenge 4: Consumer demand response

AI-transformed

Final customers with fixed-price contracts now have the right to participate in demand response programmes.

Advanced data analytics and automation technologies to run such programmes have materialised faster than expected.

AI transforms both sides of demand response. On the forecasting side, machine learning models now predict demand response behaviour by learning from weather, social events, time-of-day patterns, and individual consumption histories. On the consumer side, AI-driven home energy management systems — smart thermostats, EV charging optimisers, heat pump controllers — automate participation entirely. Consumers no longer need to manually “adjust usage based on market signals.” AI agents can do it for them.

The challenge has shifted from “how do we integrate consumers into demand response?” to “how do we ensure AI-automated demand response doesn’t create correlated behaviour that destabilises the grid?”.[11]

Challenge 5: Bidirectional charging (V2G)

AI-accelerated

Vehicle-to-grid technology is accelerating. Volkswagen/Elli/Mercedes-Benz/The Mobility House and BMW/e.on are launching V2G-capable models in 2026[12]. Removing double grid fees from 2026 onwards in Germany may increase V2G economically viability[13].

AI contributes meaningfully to the optimisation layer. Deep reinforcement learning and agentic AI systems now coordinate charging and discharging across EV fleets, optimising for price signals, grid stability, and battery health simultaneously.

Some core challenges – protocol standardisation across car manufacturers, data quality issues from different charging points, billing complexity for bidirectional energy flows at different locations – remain unsolved by AI. These are industrial coordination and regulatory problems.

Challenge 6: Peak shaving

AI-accelerated

Grid operators’ ability to request consumption cuts during price crises creates a data challenge: Distinguishing real electricity generation from virtual generation becomes trickier when demand-side peak shaving overlays the picture.

AI improves the accuracy of this distinction. Pattern recognition on time-series data can flag anomalies more reliably than rule-based systems. Machine learning models can learn the signatures of peak shaving events and separate them from organic demand fluctuations. But the fundamental challenge — consolidating different data lanes for the same measurement points into a coherent EDM system — remains a data architecture problem. AI is a sharper tool for the job. It is not a different job.

However, as ACER did not recommend amending the legal framework to permit the use of peak shaving outside officially declared electricity price crises, the de facto use of the instrument is rather unlikely.[14]

Challenge 7: Government-mandated below-cost supply

Still fully real

National governments and the European Council retain the “safety switch” to force suppliers to provide electricity below cost during declared crises. This is a political and market risk, not a data problem.

AI can improve stress testing and scenario modelling for market risk but no algorithm eliminates the fundamental business risk that a government can force energy suppliers to sell at a loss. Not surprising is the energy industry’s view against price intervention in general[15].

II. Long-term markets

Challenge 8: PPAs reshaping the market

AI-transformed

Power Purchase Agreements have not just become more common — they have reshaped the market. European PPA volumes actually declined to 13.1 GW in 2025 (from 15.3 GW in 2024), and globally, corporate PPA volumes fell 10% to 55.9 GW. But the headline masks a structural shift: AI data centres now dominate the buyer side, with Meta, Amazon, Google and Microsoft alone accounting for 49% of all global PPA activity. [16] AI itself is the biggest driver of PPAs. AI data centres are now among the largest PPA buyers globally: Meta was the single largest corporate clean-energy buyer in 2025, signing more than 10 GW of power purchase agreements (around 29 GW contracted to date)[17], while Amazon is the world’s largest corporate buyer of carbon-free energy, with more than 700 projects across 28 countries, including six offshore wind farms in Europe.[18]

AI transforms PPA valuation. Fundamental electricity market models run with machine learning approaches model capture prices — the key variable in PPA economics. AI-driven deal optimisation, automated contracting, and real-time curtailment forecasting are emerging capabilities.

More PPAs with more complex structures — aggregated, community-based, 24/7 matched — require more sophisticated valuation than ever. But AI provides the tools to handle that complexity. Producers without AI-capable portfolio management systems will struggle to compete for the best PPA terms.

Challenge 9: Long-term transmission rights

AI-transformed

Long-term transmission rights valuation requires location-specific, technology-dependent long-term price forecasting – a tricky quantitative analysis.

This sits squarely in AI’s sweet spot. ML-based price forecasting now matches or outperforms traditional quantitative methods for energy markets, with the strongest evidence at shorter horizons; the multi-year forecasts that LTTR valuation requires remain considerably harder[19]. AI-native ETRM systems are specifically designed for advanced scenario modelling across multiple bidding zones and time horizons.

Challenge 10: Virtual hubs

Still fully real

Regional virtual trading hubs remain largely speculative, pending the EU Commission’s impact assessment.[20] Political resistance – particularly in Germany, where zone-splitting is contentious – has not eased: following the TSOs’ bidding-zone review report (April 2025) and ACER’s Opinion (September 2025), the decision now rests with member states and, failing unanimous agreement, the European Commission – with Germany opposed to a split.

AI helps process the additional market data that pooled zones would generate. But the challenge here is primarily political and structural. AI can improve market data analysis and position management for virtual hubs, but it cannot resolve the political economy of whether they should exist.

Challenge 11: Full market area coverage

Still fully real

Electricity suppliers with more than 200,000 customers must now offer fixed-term, fixed-price contracts across their entire market area. In Germany, with roughly 850 distribution network areas and diverse network charges, this remains a formidable operational challenge.

AI changes very little here. The difficulty is regulatory heterogeneity: managing interfaces with price comparison platforms, calculating contract values across hundreds of different tariff zones for network charges, scaling operations without disproportionate IT costs. These are organisational and regulatory problems.

Challenge 12: Multiple suppliers per consumer

AI-accelerated

Customers may have multiple electricity supply contracts — different suppliers for a heat pump and an electric car, or a neighbour’s rooftop solar plus a utility for residual demand. Multiple metering and billing points for a single connection point are the consequence.

AI now significantly improves residual load forecasting with multiple supply points, learning consumption patterns across device types and time periods. But the underlying challenge – overhauling IT infrastructure to handle multiple data streams and metering points per connection – remains a systems integration problem.

Challenge 13: Energy sharing

AI-accelerated

Easier energy sharing through energy communities will create new demands on data quality, aggregation, and credit risk modelling. Time-series data from different distribution system operators must be consolidated at community level, often across multiple distribution or transmission networks.[21]

AI improves time-series data quality management and community demand modelling. But the core challenges — interoperability between DSOs, new aggregation levels in EDM systems, credit risk for heterogeneous community groups — are data architecture and financial modelling problems. AI sharpens the tools. The underlying engineering work is the same.

III. Market support

Challenge 14: CFDs as central support mechanism

AI-accelerated

Two-way Contracts for Difference are now the mandatory model wherever member states provide direct price support for new investments in renewable electricity and nuclear power. Utilities must value CFDs accurately and manage capped earnings risk across varying regional regulations. Additional guidance on CFD design has been published by the EU Commission.[22]

AI improves financial modelling for energy-specific CFDs. The regulatory complexity — different requirements across 27 member states, transition periods, special rules for different assets — is inherently a compliance and legal challenge. AI helps with the maths and the paperwork.

Challenge 15: Non-fossil flexibility support

AI-accelerated

Member states can apply support mechanisms for non-fossil flexibility — demand-side response, energy storage, capacity payments. The challenge is navigating diverse national schemes and integrating flexibility resources into existing operational frameworks.

AI can optimise demand-side response dispatch and storage scheduling. However, the core difficulty is policy coordination: different countries, different schemes, different rules. That is a regulatory jigsaw puzzle, where AI can help in analysing the regulatory details.

Challenge 16: Grid operator transparency

Still fully real

Grid operators must publish detailed data on available capacity for new connections, combining time series, graph data, and spatial data. This remains a hard data management and engineering challenge – though progress is visible.

AI can assist with data modelling and visualisation. But overhauling data management systems to combine heterogeneous data types and keep them current with ongoing grid expansion is fundamentally an infrastructure and data engineering problem. Capacitypedia, the pan-European portal launched in May 2026 by ENTSO-E and the EU DSO Entity[23], is a step in the right direction – but at this stage it is rather a curated link list aggregating references to individual TSO/DSO capacity publications, not a consolidated data platform. The underlying engineering work of harmonising definitions, granularity, and update cycles across hundreds of grid operators remains ahead.

Conclusion: The new magic mix

Eighteen months ago, I concluded that managing the EU’s electricity market reform’s digital challenges requires a mix of knowhow in data, risk management, trading, software engineering, and industry expertise. That remains true. But the mix needs updating.

AI has not eliminated any of the 16 challenges. It has, however, created a sharp dividing line between market players who integrate AI into their energy data management, trading, and risk systems — and those who do not. In five areas (gate closure times, dynamic pricing, demand response, PPAs, and LTTRs), AI-native solutions have become table stakes. In six more, AI meaningfully accelerates the path to compliance. Only five challenges remain entirely outside AI’s reach, anchored in regulatory and political realities.

For the updated magic mix, I would add one ingredient: AI orchestration expertise — the ability to integrate machine learning models into existing EDM and ETRM workflows without treating them as black boxes. Energy markets demand explainability, auditability, and regulatory compliance. Deploying AI that satisfies those requirements, while delivering the speed and accuracy gains the sector needs, is where firms with deep energy domain knowledge will differentiate.

The EU’s electricity market reform continues to push the sector toward more digitalisation, more real-time data, and more complexity. AI does not reduce that complexity. But it gives us tools that can match it.
