National Grid plc: core business model

National Grid plc owns and operates regulated electricity and gas transmission systems. In the UK, it manages the high-voltage electricity grid interconnecting power stations to distribution networks. The company also runs the gas National Transmission System. These assets generate stable revenues through regulated returns approved by Ofgem, the UK energy regulator.

In the US, National Grid delivers electricity to over 7 million customers in upstate New York, Massachusetts, Rhode Island, and Long Island. Its transmission infrastructure supports renewable integration, including offshore wind connections. The business model relies on rate cases filed with state regulators like the New York Public Service Commission, ensuring predictable cash flows.

The company's strategy emphasizes capital investment in grid upgrades to handle growing loads from data centers, EVs, and electrification. National Grid targets £60 billion in total investments through 2029 across its networks, with a focus on reliability and decarbonization.

Main revenue and product drivers for National Grid plc

Regulated transmission represents over 90% of National Grid's earnings. Returns are set via multi-year price controls, such as RIIO-2 in the UK covering 2021-2026. In the US, revenues come from approved rate base growth, with recent filings seeking billions for grid hardening against extreme weather.

Key drivers include asset base expansion and allowed equity returns. For fiscal year 2025, National Grid reported underlying operating profit of £3.6 billion, up 6% year-over-year, driven by US investments. Electricity transmission volumes rose amid higher renewable output.

Interconnectors like the UK-France IFA2 and North Sea Link provide additional revenue from cross-border power trading. National Grid also earns from balancing services, optimizing grid stability in real-time.

Industry trends and competitive position

The global push for net-zero emissions boosts demand for transmission owners like National Grid. In the US, the Inflation Reduction Act spurs grid investments, with National Grid positioned to connect offshore wind farms to New York City. Competitors include Eversource and Avangrid, but National Grid's scale in high-demand corridors gives it an edge.

Challenges include supply chain delays for high-voltage equipment and permitting hurdles for new lines. National Grid mitigates this through joint ventures and advanced conductor technologies to upgrade existing infrastructure.

Why National Grid plc matters for US investors

National Grid's US operations contribute about 40% of group profits, offering exposure to American energy transition without full domestic regulatory risk. Its NYSE listing via ADRs (NGG) provides easy access for US portfolios. The company's role in powering Northeast tech hubs and manufacturing resurgence ties it to US economic growth.

Main revenue and product drivers for National Grid plc

National Grid benefits from monopoly-like positions in transmission, insulated from retail competition. US rate cases in 2024 approved $4.5 billion in capex for New York alone, supporting EPS growth. Dividend policy targets 5% annual increases through 2029, appealing to income-focused investors.

Conclusion

National Grid plc stands as a cornerstone of reliable energy infrastructure across the Atlantic. Its regulated model delivers steady returns amid surging power needs.
