National Grid plc: core business model

National Grid plc operates high?voltage electricity transmission and gas networks, which are considered critical infrastructure in the UK and parts of the US Northeast. Its business model is largely regulated, meaning returns are set by regulators based on allowed capital employed and performance metrics, according to the group’s annual report for the financial year ended 31 March 2025 published in 05/2025, as summarized by National Grid annual report as of 05/2025.

In practice, this structure gives National Grid plc a relatively predictable earnings base compared with many unregulated utilities, but it also ties its profitability to regulatory determinations on allowed returns and efficiency. In the UK, the company’s electricity transmission and gas system operations are governed by the RIIO framework overseen by Ofgem, while in the US its subsidiaries operate under state?level regulation in New York and New England, according to regulatory disclosures summarized by Ofgem documentation as of 03/2025.

This regulated model requires large, ongoing capital expenditure on grid reinforcement, interconnectors and digital systems, with cost recovery spread over long asset lives. National Grid plc typically funds these investments through a mix of operating cash flow, debt issuance and, at times, equity measures, as outlined in its capital allocation commentary in the 2024–2025 financial year results released in 05/2025, according to National Grid results materials as of 05/2025.

Main revenue and product drivers for National Grid plc

The group’s revenue primarily stems from charges levied on energy suppliers and distributors for using its transmission and distribution networks. In the UK, these include transmission network use?of?system charges and system operator fees, while in the US revenues are largely determined through rate cases with state regulators. For the year ended 31 March 2025, National Grid plc reported multi?billion?pound revenues across its UK and US network divisions, with regulated asset growth driven by energy transition investments, according to the company’s 2024–2025 annual report published in 05/2025 and summarized by National Grid annual report as of 05/2025.

Key growth drivers include connecting new renewable generation, reinforcing transmission lines to handle higher electricity flows, and upgrading distribution networks to accommodate electric vehicle charging and heat pumps. In its 2024–2025 reporting, National Grid plc highlighted increasing capital expenditure in both the UK and US to support net?zero policies and electrification trends, while also signaling that regulatory decisions on allowable returns remain a central determinant of earnings, according to its investor presentation released in 05/2025, as referenced by National Grid full?year results presentation as of 05/2025.

Beyond traditional cables and pipelines, National Grid plc also derives revenues from interconnectors linking the UK with continental Europe, such as those connecting to France and the Netherlands. These assets can benefit from price differentials between power markets, though they remain subject to regulatory and market arrangements that can change over time. The company has also been developing smart grid initiatives and digital solutions designed to improve network efficiency, which can earn performance incentives under regulatory frameworks, according to technology and innovation sections in its 2024–2025 annual report published in 05/2025, as summarized by National Grid sustainability and innovation report as of 05/2025.

Conclusion

National Grid plc occupies a pivotal position in the UK and US energy systems, with a regulated business model that can provide earnings visibility but also exposes the group to political and regulatory scrutiny. Its recent financial reporting and investment plans underscore the scale of grid upgrades required for the energy transition, as detailed in filings and presentations for the 2024–2025 financial year released in 05/2025. For US?focused investors looking at international utility exposure, the stock offers insight into how large network operators navigate decarbonization policies, regulatory negotiations and capital?intensive infrastructure programs without providing any guarantee about future share price performance.
