NATURAL GAS UTILITY OPERATIONS
Natural Gas Utility Trends
The most significant developments in the natural gas operations of the utility subsidiaries are continued volatility in natural gas
market prices, safety requirements for natural gas pipelines and the continued trend of declining use per residential customer, as
well as small commercial and industrial customers (C&I), as a result of improved building construction technologies, higher
appliance efficiencies and conservation. From 2000 to 2010, average annual sales to the typical residential customer declined
from 96 MMBtu per year to 82 MMBtu per year and to a typical small C&I customer declined from 441 MMBtu per year to 394
MMBtu per year, on a weather-normalized basis. Although wholesale price increases do not directly affect earnings because of
natural gas cost-recovery mechanisms, high prices can encourage further efficiency efforts by customers.
