Utility companies generate and deliver electricity, natural gas and water. Most operate as regulated monopolies in their service areas, which gives them predictable revenue and makes their stocks popular with income-focused investors.
What's in the utilities sector
- Regulated electric and gas utilities: own power lines, pipelines and often power plants, and earn a return approved by state regulators.
- Water utilities.
- Independent power producers and renewable developers: sell electricity at market or contracted prices, with less regulation and more variable profits.
- Multi-utilities combining several of these businesses.
How regulated utilities make money
Regulators allow a utility to earn a set return on the money it invests in its network, called the rate base. To grow earnings, a utility typically needs to keep investing, for example in grid upgrades or new generation, and win approval to recover those costs through customer rates. That's why utilities spend heavily and often carry large debt loads.
Metrics that matter
- Dividend yield and growth, and the payout ratio. Utilities often pay out a large share of earnings.
- Rate base growth and the company's planned capital spending.
- Allowed return on equity and the quality of its relationship with regulators.
- Debt: high leverage is normal for utilities, so compare debt measures and credit ratings with peers rather than with other sectors.
- Valuation: the P/E ratio relative to peers and to the company's own history.
Key risks
- Interest rates: utilities borrow heavily and compete with bonds for income investors, so their shares often fall when rates rise. See how interest rates affect stocks.
- Regulatory decisions: an unfavorable rate case can cut expected earnings.
- Weather and wildfire liability: storms and wildfires can cause large costs and legal claims.
- Slow growth: earnings typically grow at a modest, steady pace.
Ways to invest
Utilities ETFs such as XLU or VPU spread money across the sector. Because of their steady income, many investors use utilities to balance more volatile holdings; see how to diversify and what is beta. Note that the general StockEngine Score may rate utilities' financial health lower than peers in other sectors because of their normal debt levels; compare utilities with each other.
