Search online: Use search terms like "[your location] water utility" or "[your location] electric company."
Consult government websites: State public utility commissions often maintain lists of licensed utilities.

Investing in Public Utilities: Considerations

Investing in public utility stocks can be appealing due to their often stable and predictable earnings. However, it’s crucial to understand:

Regulation: Government regulation heavily influences these companies' pricing and operations.
Infrastructure: Maintaining and upgrading aging infrastructure requires significant capital investment.
Environmental Concerns: The industry is increasingly focused on sustainability and clean energy transition.
