Business Model
What each company does and how it makes money
NextEra Energy is a major electric utility and clean energy developer that operates regulated utilities in Florida while also building renewable projects across North America. It makes money primarily through regulated utility operations — about 60% of earnings — and its competitive energy generation business that develops wind, solar, and battery storage projects. The company's key advantage is its massive scale in renewable energy development and its first-mover position in clean energy infrastructure, giving it unmatched project execution capabilities and cost advantages.
Duke Energy is a regulated electric and gas utility serving customers across six states in the Southeast and Midwest. It makes money primarily through regulated rate-based returns on its electric utility infrastructure (~70% of revenue) and gas distribution operations (~20%), with additional income from commercial renewable energy projects. Its key advantage is its monopoly status as a regulated utility in its service territories, which provides stable, predictable returns through government-approved rate structures.
National Grid is a regulated utility that operates electricity and gas transmission and distribution networks in the UK and northeastern United States. It earns revenue through regulated asset returns — collecting fees from customers for using its infrastructure — with its UK transmission business contributing roughly 40% of operating profit and its US operations about 35%. The company's primary moat comes from its natural monopoly position as an owner of critical energy infrastructure, protected by high regulatory barriers to entry and long-term, stable rate-of-return frameworks.

(NEE) a "Buy" — based on 36 analyst ratings — the highest consensus in this comparison.

Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

At the gross margin level — before operating expenses — NGG leads at 77.4%, reflecting greater pricing power or product mix advantage.

06Is NEE or DUK or NGG more undervalued right now?
The PEG ratio (forward P/E divided by expected earnings growth rate) is the most precise measure of undervaluation relative to growth potential. By this metric, Duke Energy Corporation (DUK) is the more undervalued stock at a PEG of 0.66x versus National Grid plc's 2.23x. A PEG below 1.0 is traditionally considered the threshold for growth-adjusted undervaluation.

07Which pays a better dividend — NEE or DUK or NGG?
In this comparison, NEE (2.4% yield), NGG (2.2% yield) pay a dividend. DUK does not pay a meaningful dividend and should not be held primarily for income.
08Is NEE or DUK or NGG better for a retirement portfolio?
For long-horizon retirement investors, National Grid plc (NGG) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.04), 2.2% yield). Both have compounded well over 10 years (NGG: +84.4%, DUK: +128.1%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.
09What are the main differences between NEE and DUK and NGG?
Both stocks operate in the Utilities sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both. NEE, NGG pay a dividend while DUK does not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
