What are utilities?
Utilities are companies that produce and deliver basic essential services such as electricity, natural gas and water. These services are delivered by a network of assets that require the use of public rights-of-way. Crucially, these networks exhibit attributes of a natural monopoly: the extensive capital required to construct the assets make it difficult for another company to compete profitably against the incumbent.
Due to this natural monopoly, governments have generally operated utilities but in recent decades they have handed the responsibility to private operators under licence.
To gain this licence, a utility agrees to submit to economic regulation governing the rates it can charge customers. In exchange, the regulator promises to set prices fairly so that the utility can cover its costs effectively and make a reasonable profit considering the risks involved. While returns set by regulators can be modest compared with other sectors, utilities are often assured a minimum return regardless of how the economy is performing because demand for their services is constant. The minimum returns provide an incentive for future or potential asset owners to invest in new or existing infrastructure. This means utility stocks can provide stable earnings and cash flows.
