RESILIENCE-FOCUSED ELECTRICITY REGULATION AFTER NET-ZERO

1. Concept

Resilience-focused electricity regulation after net-zero concerns the legal framework needed to ensure that a deeply decarbonised electricity system remains reliable, adaptable, secure and capable of recovering from major disturbances. Net-zero does not end electricity regulation; it changes its priorities. As heating, transport, industry and digital infrastructure become increasingly dependent on electricity, failures in the power system can produce wider economic and social consequences.

The regulatory objective therefore evolves from merely decarbonising generation toward creating a system capable of withstanding extreme weather, cyberattack, equipment failure, supply-chain disruption, renewable intermittency and sudden demand shocks.

In Great Britain, this emerging approach is already visible. The 2025 National Policy Statement for electricity networks states that future electricity infrastructure must support increasing demand, net-zero objectives and energy security while also being resilient to flooding, storms, higher temperatures, subsidence and coastal erosion.

2. Legal Framework

The Climate Change Act 2008 establishes the legally binding 2050 net-zero target and carbon-budget framework. The Energy Act 2023, section 202, amended section 3A of the Electricity Act 1989 so that Ofgem must consider the Secretary of State's compliance with the statutory net-zero target and carbon budgets when exercising its regulatory functions.

At the same time, the Energy Act 2023 establishes statutory objectives for the system operator encompassing net zero, security of supply, efficiency and economy. These objectives illustrate that decarbonisation and resilience are legally complementary rather than mutually exclusive.

Modern resilience regulation therefore includes:

anticipatory network reinforcement;

climate-adaptation standards;

storage and demand-side flexibility;

cyber and physical-security requirements;

interconnection and diversified supply;

emergency restoration capability;

asset-maintenance obligations; and

resilience performance reporting.

The government's electricity-networks framework similarly envisages investment ahead of immediate need so that networks remain secure and resilient while accommodating rapid electrification.

3. Friends of the Earth Ltd v Secretary of State for BEIS [2022] EWHC 1841 (Admin)

Facts: Environmental organisations challenged the UK Government's Net Zero Strategy under sections 13 and 14 of the Climate Change Act 2008.

Legal Issue: Whether the Secretary of State had received adequate information about how proposed policies would achieve statutory carbon budgets and whether the published strategy complied with statutory reporting requirements.

Judgment: The High Court held that aspects of the decision-making and reporting process failed to comply with the Climate Change Act.

Legal Principle/Ratio: Statutory climate objectives require a sufficiently reasoned and accountable governmental implementation framework; broad policy aspirations alone are insufficient where Parliament has imposed specific legal duties.

Significance: For post-net-zero resilience regulation, the case demonstrates that electricity-transition strategies must be supported by transparent evidence, implementation mechanisms and regulatory accountability rather than simply long-term targets.

4. R (Packham) v Secretary of State for Transport

Facts: The claimant challenged governmental infrastructure decisions partly by reference to climate obligations and the net-zero transition.

Legal Issue: How far statutory climate objectives constrain governmental choices concerning infrastructure and transition pathways.

Judgment: The courts recognised that government retains substantial discretion concerning the means used to achieve statutory climate objectives.

Legal Principle/Ratio: Net-zero legislation fixes important outcomes but leaves policymakers significant latitude in selecting the measures used to reach them. The High Court in Friends of the Earth expressly referred to this principle.

Significance: Resilience regulation may therefore employ multiple lawful techniques—including capacity markets, network reinforcement, storage, interconnection and demand flexibility—provided statutory objectives are properly considered.

5. Resilience After Decarbonisation

A highly renewable system requires regulation capable of managing low-wind periods, extreme weather and rapidly changing power flows. Storage, flexible demand and interconnectors become increasingly important. The government's Clean Flexibility Roadmap identifies flexibility as essential to integrating renewable generation while reducing system costs.

Resilience also requires stronger physical infrastructure. Current UK policy expressly recognises that network planning must account for system-capacity and resilience requirements and climate-related risks.

6. Overall Significance

Post-net-zero electricity law should therefore move from a narrow decarbonisation model to an integrated decarbonisation-resilience model. Regulatory success will depend not merely on producing zero-carbon electricity, but on ensuring continuous supply during climatic, technological and security disruptions. The future regulatory standard is consequently likely to combine net-zero compliance, anticipatory investment, climate adaptation, flexibility, cybersecurity, reliability and rapid system recovery within a single framework of accountable electricity governance.
