Six key facts about National Grid, one pattern: the company straddles two regulated markets with distinct ownership and regulatory models.
| Label | Value |
|---|---|
| Formation | 1990 (privatisation of UK electricity industry) |
| Head Office | 1-3 Strand, London, WC2N 5EH |
| CEO (2024) | John Pettigrew |
| Employees (UK) | ~15,000 (part of 30,000 global) |
| Ownership | Publicly traded (LSE: NG) |
| UK Grid Length | 7,000 km of overhead lines and 1,400 km of underground cables |
Who is the CEO of National Grid?
John Pettigrew has served as National Grid’s Chief Executive Officer since April 2016. He joined the company as a graduate in 1991 and worked his way up through engineering and operations roles, according to Companies History.
Largest shareholder of National Grid
Institutional investors hold the majority of National Grid’s shares. According to Simply Wall St’s ownership analysis, institutions owned 77.1% of the London-listed stock as of its latest snapshot. The cited snapshot does not name a single largest institution; Vanguard Group is frequently cited in market reports as the top institutional holder. The general public holds 21.9% of the shares.
Current board of directors
National Grid’s board reflects its dual UK-US operations. Its governance document lists directors with experience in both markets, including the CEO, the chair, and independent non-executive directors.
John Pettigrew’s long tenure and insider promotion signal stability, but the high institutional ownership means the board must answer to large shareholders who can push for strategic changes.
The pattern: a long-tenured insider runs the company, but institutional owners hold the power to reshape the board if performance slips.
Is National Grid UK privately owned?
National Grid plc is a publicly traded company, not a private firm. It is listed on the London Stock Exchange under the ticker LSE: NG. The company is a British multinational, incorporated in the UK, with its headquarters in London. Its operations span the UK and the northeastern US, but the corporate structure remains British.
National Grid ownership structure
As a public limited company, National Grid is owned by its shareholders. The largest category is institutional investors (77.1% per Simply Wall St), followed by the general public (21.9%). There is no government ownership, though the company is heavily regulated by Ofgem in the UK and by state regulators in the US.
Is National Grid an American company?
No. Despite having significant US operations—electricity and gas networks in New York, Massachusetts, and Rhode Island—National Grid is a British company. Its US subsidiary, National Grid USA, is a wholly owned part of the group. The parent’s legal domicile and primary stock listing are in the United Kingdom.
Is National Grid a company in the UK?
Yes. National Grid is a UK-registered company and a constituent of the FTSE 100 index. Its UK operations include the high-voltage electricity transmission network in England and Wales, and the gas transmission network across Great Britain. The company also owns the electricity distribution network in some regions, but most UK distribution is handled by other companies like UK Power Networks.
National Grid is a UK company with a dual identity—its largest revenue source is now the US, where it faces different regulatory risks. That split creates complexity for investors tracking the stock.
How does the National Grid work in the UK?
National Grid’s primary role in the UK is operating the high-voltage electricity transmission network that connects power stations to regional distribution networks. It also manages the gas transmission system. The company does not sell electricity directly to households; that is the job of suppliers like British Gas or EDF.
Role of National Grid in electricity transmission
The grid consists of about 7,000 km of overhead lines and 1,400 km of underground cables. National Grid balances supply and demand in real time using the System Operator function, which is now legally separate under the Energy Act 2023. The company also operates interconnectors that link the UK to France, Belgium, the Netherlands, and Norway.
Is the National Grid the same as UK power networks?
No. “UK power networks” is a broad term that includes the transmission network (National Grid) and the regional distribution networks owned by companies like UK Power Networks, Scottish Power, and SSE. National Grid is the transmission owner in England and Wales, but it is not the distributor. Distributors are the ones that bring electricity from the transmission grid to homes and businesses.
For comparison, here are the regulated asset values across National Grid’s key regions, based on the company’s 2024 investor presentation:
| Region | Regulated Asset Value (RAV) 2023 (£m) | Year-on-Year Change |
|---|---|---|
| UK Electricity Transmission | 1,290 | +43% |
| New England (US) | 814 | +3% |
| New York (US) | 1,569 | +25% |
| National Grid Ventures | 279 | −12% |
Data from National Grid – Delivering investment at pace (2024 investor presentation).
The pattern: UK and New York RAVs are growing fast, driven by regulatory-approved investment programmes, while the Ventures segment shrinks, partly due to disposals.
Why is National Grid stock falling?
National Grid’s share price has faced headwinds in 2023 and 2024. According to TipRanks’ stock analysis, the stock’s decline is linked to a combination of regulatory changes in the UK, interest rate hikes, and inflation pressure on capital-intensive projects. In October 2024, CEO John Pettigrew was reported to have sold shares worth £2.3 million, which may have added to market jitters.
Recent stock performance of National Grid
The stock has been underperforming the FTSE 100 in 2024. Data from Simply Wall St’s ownership snapshot shows that the share price has fallen about 12% year-to-date. The company’s dividend yield, historically around 5%, remains attractive, but the capital value has eroded.
Factors influencing National Grid share price
Key factors include the UK energy price cap, which limits returns on regulated assets, and the rising cost of debt. National Grid’s £60 billion investment plan requires significant borrowing, and higher interest rates reduce the net present value of future cash flows. In the US, state regulators in New York have been pushing back on rate increases, adding regulatory uncertainty.
For income-focused investors, the dividend yield is the main draw. But the falling share price means total return is negative this year. The next quarterly report will show whether earnings can match the investment pace.
The implication: the dividend is only half the return story; interest rates and regulator decisions will determine whether the share price recovers.
What is the National Grid in Nigeria?
The National Grid in Nigeria refers to the country’s electricity transmission system, which is owned and operated by the Transmission Company of Nigeria (TCN). It is not connected to National Grid plc. The Nigerian grid faces chronic infrastructure challenges, including frequent collapses and limited capacity.
Ownership and operation of the Nigerian grid
TCN is a state-owned enterprise, though there have been efforts to privatise it. Unlike the UK, where the grid is privately owned and regulated, Nigeria’s grid remains under government control. The World Bank and other development institutions have funded upgrades, but the system still loses about 10% of transmitted power due to technical losses.
Difference from National Grid plc
National Grid plc has no ownership or operational stake in the Nigerian grid. The similarity is only in name—both use “National Grid” to describe a country’s high-voltage transmission network. The Nigerian grid is much smaller, less reliable, and operates under a different regulatory framework.

Quotes on National Grid’s outlook
“Delivering investment at pace, in an exciting new era of growth.”
National Grid – 2024 investor presentation
“National Grid’s institutional ownership at 77.1% indicates strong investor confidence, but the stock’s recent decline suggests the market is pricing in regulatory headwinds.”
The common thread: the company frames its investment plan as growth, while independent analysis flags the market’s regulatory doubts.
Summary
National Grid is a vital infrastructure operator with a split personality: a UK-listed company that earns a growing share of its profits in the US. For UK investors, the dividend yield is a strong pull, but the falling share price and regulatory uncertainty in both countries demand caution. For Nigerian readers curious about the grid, the name is the same—the reality is not. The choice is clear: either the company delivers on its £60 billion investment plan while regulators keep returns in check, or the stock will continue to trade at a discount.
