Summary:
Companies in the public utilities sector include firms that provide essential public services. This includes natural gas, electric power, and water and wastewater services to residential, commercial, and industrial properties. Other services offered by utility companies also include clean and renewable energy sources like wind energy and solar power, and telecommunication services such as cable, internet, and television services.
As Americans, public utility services are something most people don’t think about all that much — that is, until we don’t have them. We often take these services for granted until we lose power during the warmer months and the air conditioning dies, or our internet connection suddenly cuts out during a video conference.
Obviously, public utility companies are an integral part of our daily existence. Today, we’ll take a look at different companies in the public utilities field, how it’s evolving, and the pros and cons of investing in this industry.

About the utilities sector

Before we get into exactly what companies are in the public utilities field, let’s take a closer look at the utilities sector and what kinds of firms are involved in producing, providing, and delivering these vital public services.
Utility companies are generally large corporations that provide a multitude of services to their customers or may only offer a single service, such as natural gas utilities or water and sewer services. The firms that deliver these services to your door are often subsidiaries of the major corporations going by a variety of business names.
In addition to the basics of natural gas, electric power, water, and sewage services, some companies focus on energy efficiency alternatives, such as renewable energy like solar panels and wind turbines. Also, many “traditional” utility firms are now branching out into these areas of renewable energy as the world moves toward cleaner energy sources and a greener planet.

Commonalities of the public utility industry

The public utilities sector is a capital-intensive and heavily regulated industry. This means they depend upon a constant influx of funding to finance frequent and expensive infrastructure upgrades, infrastructure maintenance, and new asset purchases.
Despite the ongoing need for cash flow, utilities are generally considered very stable and often become a more popular investment during times of economic downturns or recessions. This is because they tend to offer consistent dividends to investors while having much less price volatility when compared to the rest of the market.
However, during times of economic growth, public utilities tend to become less popular with investors because the gains are slower than other, riskier securities. Still, many investors that put money into public utilities tend to view them as long-term investments because of the stable returns and resistance to economic downturns.
For example, back in the 70s and 80s utility providers were faced with a lot of challenges. They were looking at huge debts, blackouts, fuel costs rising astronomically, and increasing regulations. Some went bankrupt, but those who survived and are still around today have proven the ability to withstand even the most trying circumstances.
That’s why, when the overall market isn’t doing well, utility providers still manage to thrive and are considered among some of the safest and best investments for stable returns and slow but steady wealth building.

How to invest in public utility companies

Whether you want to invest in companies that provide electricity, water utilities, natural gas, water and wastewater services, or other services, there are plenty of options. You can buy individual utility stocks or bonds, for example, or invest in exchange-traded funds (ETFs) to give you broader exposure to the public utilities industry.
Investing in individual stocks can be risky, but an ETF combines a basket of assets — in this case, multiple public utility companies — thereby diluting the risk to investors. A utility ETF might include an electric company, corporations that offer water services or natural gas utilities, own power plants, or a combination of all of those essential services and more. The brokerages below make it easy to invest in ETFs.
