DNO Data Sharing Dispute

A DNO refuses to publish detailed LTDS feeder capacity data, citing cybersecurity concerns. Connection applicants cannot assess queue positions. Ofgem must decide whether to mandate publication.

AI Forecast Error

A public-facing demand forecast tool produces incorrect predictions during a cold snap, causing market participants to over-procure. NESO must explain the error and restore confidence.

Connection Queue Reform

Queue volume, milestone discipline, and delivery sequencing remain central issues as Ofgem and NESO continue implementing TMO4+ and wider connections reform. DNOs want credible demand signals, while developers remain sensitive to queue reprioritisation and implementation timing.

DSO Flexibility Procurement

A DNO transitions to DSO capabilities and must procure flexibility services. Incumbent flexibility providers allege the DNO is favouring its own network solutions. Market neutrality is questioned.

Smart Meter Data Access

DNOs request half-hourly smart meter data for network planning. Consumer groups raise privacy concerns. Suppliers argue competitive harm. Who gets access to what data, and under what conditions?

Gas Supply Emergency

National Gas declares a gas deficit warning due to supply disruption. NESO must coordinate electricity and gas system responses. Industrial users face curtailment and switching to electricity.

Nuclear Safety Event

The Office for Nuclear Regulation receives a safety concern report at a fictional AGR station. NESO must balance safety scrutiny, public communication, and maintaining generation adequacy.

Heat Network Consumer Complaint

A heat network customer has no heating in winter and institutions must decide how the live Ofgem regime, local support, and further standards should be used in practice.

Hydrogen Blending Decision

A fictional future proposal for higher hydrogen blending in the NTS raises safety, evidence, and consumer-cost questions.

CfD Strike Price Dispute

A CfD holder claims the reference price methodology undervalues their renewable output. Elexon and DESNZ must adjudicate a complex technical and commercial dispute.

Code Modification Conflict

A BSC modification conflicts with a simultaneous DCUSA modification. Cross-code coordination is needed. RECCO must facilitate resolution amongst competing governance bodies.

Interconnector Outage

A major interconnector trips during peak winter demand. NESO must manage the generation shortfall. Balancing frequency, prices and public communication.

Fuel Poverty Crisis

Energy bills rise sharply due to global prices. Citizens Advice demands emergency intervention. Ofgem must balance consumer protection with supplier viability.

REMA Implementation

A fictional future market-reform package is announced and participants must adapt. The case tests transition governance rather than current live rules.

CCS Access Dispute

Two industrial emitters compete for limited CO2 transport capacity in a carbon capture and storage network. NSTA must allocate fairly between applicants.

DSO Transition

Ofgem reviews whether DNOs are genuinely transitioning to DSO capabilities or gaming the framework. Evidence of favouritism toward DNO-affiliated flexibility providers emerges.

Smart Meter Data Breach

DCC reports a data breach affecting 50,000 smart meter records. ICO and Ofgem must coordinate response. Consumer trust in smart metering is at risk.

Offshore Wind Connection Delay

A major offshore wind farm cannot connect because transmission reinforcement is years behind schedule. Clean power targets and investor confidence are at risk.

Net Zero Target Review

Government reviews whether the 2030 clean power target is achievable. Industry lobbies for delay. Environmental groups demand acceleration. Regulatory agencies must advise.
