Business Overview
National Grid is a leading electricity and gas transmission and distribution company operating primarily in the UK and northeastern United States. It generates revenue through regulated frameworks that govern its electricity transmission, distribution networks, and gas local distribution companies (LDCs). The business is segmented into UK electricity transmission, UK electricity distribution, US New York and New England operations, and National Grid Ventures, which includes interconnection and other infrastructure assets.
Performance Analysis
National Grid reported a 10.9% growth in regulated asset base (RAB) driven by a 20% increase in capital expenditure to £11.6 billion, reflecting the company’s aggressive investment ramp-up. Underlying operating profit rose to £5.7 billion, supported by higher regulatory allowances and indexation, while delivering flat controllable costs in key UK segments. The UK electricity transmission segment saw a 46% rise in capex, fueling 16% asset growth and a return on equity (ROE) exceeding baseline allowances by 100 basis points.
In the US, capital investment increased by 11% in New York and 24% in New England, driven by infrastructure upgrades and growing demand from data centers and reshoring efforts. Despite higher storm costs and depreciation, the US businesses maintained ROEs near or above allowed levels, demonstrating operational resilience. National Grid Ventures experienced a decline in profit following asset sales, reflecting a strategic focus on core regulated businesses.
- Capital Investment Acceleration: £70 billion planned over five years with two-thirds secured under regulatory agreements.
- Strong Regulatory Outperformance: UK transmission and US businesses consistently delivering returns above allowances.
- Operational Efficiency Gains: Early benefits from AI-enabled Capital Control Tower and productivity improvements in field operations.
This robust financial and operational performance sets a foundation for National Grid’s upgraded five-year framework targeting 8-10% EPS compound annual growth rate (CAGR) and 10% annual asset growth, supported by a progressive dividend aligned with inflation.
Executive Commentary

Strategic Positioning
1. Unprecedented Capital Investment and Asset Growth
National Grid is executing its largest capital program ever, with a £70 billion investment planned over five years. This investment is focused on upgrading UK transmission and distribution networks to support 35 gigawatts of new generation and 19 gigawatts of new demand, including data centers and electrification. In the US, investments in New York and New England are accelerating to meet rising demand and enhance resilience. This scale of investment positions the company to nearly double its UK regulated asset base and grow its US RAB by 50%, creating a durable platform for earnings expansion.
2. Sharpening Operational Execution Through Technology
To de-risk delivery of its capital program, National Grid is deploying AI and digital tools such as the Capital Control Tower, which provides real-time project feedback and enables proactive adjustments. The company is standardizing designs and modularizing equipment to reduce engineering cycles and procurement complexity. Operational improvements in field crew productivity, including a 30% reduction in travel time in New York gas operations, demonstrate tangible efficiency gains. These initiatives are critical to managing cost pressures and improving predictability.
3. Transforming Customer Experience and Engagement
National Grid is modernizing customer-facing platforms, particularly in the US, where over 2 million smart meters have been deployed alongside a new digital contact center platform. This enhances first call resolution and reduces wait times, reflected in an 18% increase in customer satisfaction scores. The company is also focusing on accelerating connections for large industrial and data center customers, responding to demands for speed, transparency, and certainty. The Connections Reform Program in the UK exemplifies efforts to tailor services to diverse customer needs.
4. Strengthening Regulatory and Policy Advocacy
The company is actively engaging with regulators and governments to shape frameworks that balance affordability, resilience, and system growth. In the UK, the acceptance of the T3 price control provides improved de-risking mechanisms, including allowances tied to supply chain engagement and enhanced output delivery incentives. National Grid seeks clarity on upcoming ED3 regulatory constructs and aims to influence mechanisms such as real price effects and output incentives to better align investment and returns.
5. Maintaining a Resilient Financial and Capital Structure
National Grid’s financial strategy ensures investment-grade credit ratings through disciplined leverage management, hedging currency exposures, and matching debt to regulatory asset bases. The company expects leverage to rise modestly toward the high 60% range by 2031 while maintaining strong headroom across credit metrics. Capital allocation prioritizes disciplined delivery of the investment program, with openness to selective growth opportunities in competitive transmission and offshore interconnectors that align with core capabilities and risk profiles.
Key Considerations
National Grid’s Q4 results and strategic update highlight a company balancing ambitious growth with operational rigor and regulatory engagement.
- Regulatory Visibility and Risk Mitigation: Two-thirds of the £70 billion investment plan is secured under regulatory agreements, reducing execution risk.
- Technology as a Performance Multiplier: AI and digital tools are central to improving capital project delivery and asset management efficiency.
- Customer-Centric Transformation: Enhanced digital platforms and targeted engagement are addressing evolving demand and service expectations.
- Inflation and Supply Chain Management: Three-quarters of supply chain contracts are secured, and mechanisms exist to pass through cost inflation, especially in the UK transmission business.
- Balance Sheet Discipline: Leverage is managed prudently to support growth while preserving investment-grade ratings and funding flexibility.
Risks
Key risks include regulatory uncertainty, particularly around ED3 outcomes, which could affect allowed returns and investment pacing. Supply chain disruptions and commodity price volatility, exacerbated by geopolitical tensions, pose cost and schedule risks despite proactive contracting. The company’s exposure to evolving energy demand patterns, especially large industrial and data center loads, introduces execution complexity. Additionally, regulatory frameworks that share efficiency gains predominantly with customers may limit upside for shareholders, requiring careful negotiation.
Forward Outlook
For FY27, National Grid projects:
- Capital investment growth of approximately 10% to nearly £13 billion.
- Underlying EPS growth of 13% to 15% from a baseline of 78 pence in FY26.
Management maintains its five-year financial framework targeting 8-10% EPS CAGR and 10% annual asset growth, supported by strong regulatory visibility. The company plans continued focus on efficiency, operational discipline, and regulatory engagement to sustain growth and shareholder returns.
Takeaways
National Grid’s Q4 2026 results and strategic update reaffirm its position as a leading regulated infrastructure operator with a clear growth trajectory and disciplined execution approach.
- Robust Growth Engine: The company’s unprecedented £70 billion investment plan underpins sector-leading asset and earnings growth visibility across the UK and US markets.
