Volume 34—Gas Utilities & Distributors

Industry Description

The Gas Utilities & Distributors industry consists of gas distribution and marketing

entities. Gas distribution involves operating local, low-pressure pipes to transfer natural

gas from larger transmission pipes to end users. Gas marketing entities are gas brokers

that aggregate and deliver natural gas in quantities that meet the needs of various

customers, generally through other entities’ transmission and distribution lines. A

customers, generally through other entities’ transmission and distribution lines. A

relatively smaller portion of this industry is involved in propane gas distribution;

therefore, this standard is focused on natural gas distribution. Both types of gas are used

for heating and cooking by residential, commercial and industrial customers. In

regulated markets, the utility is granted a full monopoly over the distribution and sale of

regulated markets, the utility is granted a full monopoly over the distribution and sale of

natural gas. A regulator must approve the rates utilities charge to prevent the abuse of

their monopoly position. In deregulated markets, distribution and marketing are

separated legally, and customers have a choice of which entity from which to buy their

gas. In this case, a common carrier utility is guaranteed a monopoly only over

gas. In this case, a common carrier utility is guaranteed a monopoly only over

distribution and is required legally to transmit all gas equitably along its pipes for a fixed

fee. Overall, entities must provide safe, reliable, low-cost gas, while effectively managing

their social and environmental impacts, such as community safety and methane

emissions.

Note: The Gas Utilities & Distributors industry does not include gas transmission entities

Note: The Gas Utilities & Distributors industry does not include gas transmission entities

that transport high pressure natural gas over long distances from the wellhead. Gas

transmission entities are included in the Oil & Gas—Midstream (EM-MD) industry.

Furthermore, the Gas Utilities & Distributors industry covers activities related only to gas

provision and not to electricity provision. Some utilities may operate in both gas and

provision and not to electricity provision. Some utilities may operate in both gas and

electricity markets. Entities undertaking activities related to electricity generation or

distribution also should consider the topics and metrics in the Electric Utilities & Power

Generators (IF-EU) industry.

Operating a vast network of gas pipelines, equipment and storage facilities requires a multifaceted, long-term approach to ensuring infrastructure integrity and managing related risks. Although customers depend on reliable gas supplies, entities manage substantial risks—including those related to human health, property and greenhouse gas (GHG) emissions—that result from operating gas distribution networks and related

(GHG) emissions—that result from operating gas distribution networks and related infrastructure. Ageing infrastructure, inadequate monitoring and maintenance, and other operational factors may result in gas leaks.

Furthermore, gas leaks also result

dangerous in urban areas where entities often operate. Furthermore, gas leaks also result in fugitive emissions (methane), causing adverse environmental impacts. Regulated gas utilities generally incur no direct costs for gas leaks, because the cost of gas typically is passed on to customers (though this may vary by region). However, gas leaks that result in safety-related risks or fugitive emissions may affect entities financially through a

in safety-related risks or fugitive emissions may affect entities financially through a variety of regulatory, legal and product demand channels. Accidents, particularly fatal accidents, may result in negligence claims against entities, leading to costly court battles and fines. GHG emissions may result in increased regulatory scrutiny—a critical element directly connected to financial performance, given the importance of regulatory relations

—and potential fines and penalties. Importantly, regulated gas utilities can financially benefit from capital investment opportunities to improve performance and mitigate risks related to safety and emissions, which can be factored into their rate base. Entities manage such risks through pipeline replacements, regular inspections and monitoring,

employee training and emergency preparedness, investments in technology, and other strategies such as working closely with regulators. In response to concerns about ageing infrastructure, many entities are seeking ways to expedite the replacement permitting and approval process, especially in cases where pipelines are located near densely populated areas.
