Utility services play a vital role in a nation’s economic progress as cheap and abundant supply of power keeps the wheels of development rolling. With development comes the need for more power, as cities expand, and the use of new gadgets increases.

Per U.S. Energy Information Administration (EIA), total energy use in the U.S. will increase to 106.3 quadrillion Btu in 2040 from 95 quadrillion Btu in 2012. Most of this demand is expected to come from the Industrial sector followed by the Commercial sector. (Read:

Even so, the utilities have been under review for a long time. The climate action plan of the U.S. President followed by the U.S. Environmental Protection Agency's (EPA) proposal for tightening the rules to set up new power plants are putting immense pressure on power producing units.

To meet the stringent regulation, utilities are now gradually shifting their emphasis towards natural gas and alternate energy sources to produce power. The utility operators are also implementing new technologies in generation and distribution of power. The introduction of smart meters will benefit customers while the smart-grid technology is likely to increase efficiency. (Read: 3 MLP ETFs riding out market volatility)

Utilities are by their very nature monopolistic businesses. As a result, the sector is highly regulated as the essential supplies cater to basic human needs, and governments try to ensure the prices of these supplies – water, electricity, etc. – stay within reasonable limits.

The utilities, on the other hand, try to increase prices through the filing of rate cases. The investments and costs incurred for the modernization and maintenance of reliable services are recovered through these rate cases. (Read: 3 Sector ETFs surving the market slump)

Mainly, the steady performance of the companies lures investors to the utility space. The biggest positive for the utilities is that there is hardly any viable substitute for utility services.

ETFs to Tap the Sector
 
The services provided by utilities are always in demand, while positive movement in the economy tends to increase the demand for utility services. In addition, consistent payment of dividends also makes these ETFs attractive and the defensive nature of operations insulates these ETFs from market turbulence. (See all utility ETFs here)

To Sum Up
 
The biggest positive for the utilities is that there is hardly any viable substitute for utility services. This is the most fundamental strength of the industry. Moreover, increasing demand drives this industry forward.
 
Despite the assured demand for services, the utilities have to constantly meet the high expectations of its wide customer base, adapt to a changing global economic scenario, and upgrade technologies to meet stringent environmental norms.

We hardly find utilities posting eye-catching numbers, but these companies are generally stable due to the regulated nature of operations, and they are loyal to shareholders. The strength lies in their value and yield. So, investors looking for a steady return on their investments could take a Utility ETF approach.
