CenterPoint Energy files to adjust natural gas bills for Houston-area customers
Lower wholesale natural gas prices offset proposed change to base rates

HOUSTON - July 31, 2009 - CenterPoint Energy (NYSE: CNP) today made filings with municipal regulatory authorities and the Texas Railroad Commission that will affect the amount that Houston-area customers pay for gas utility service. CenterPoint Energy is reducing the amount billed to customers through the PGA portion of a customer’s gas bill beginning in August which will have an annualized reduction of $96.7 million.

Wholesale natural gas prices have decreased nationwide and CenterPoint Energy is passing along lower prices. Through the PGA, an allowed adjustment to the gas supply charge portion of a customer bill, CenterPoint Energy passes on the cost of natural gas with no markup. The PGA typically makes up 60-70 percent of a customer bill.

“We are happy to be able to pass this natural gas price decrease on to customers because the PGA is the largest portion of a customer bill,” said Rick Zapalac, division vice president of Gas Operations in Texas. “CenterPoint Energy manages a diversified gas portfolio that balances reliability, reduced price volatility and reasonable price to meet the needs of all our customers. We work with a variety of natural gas suppliers and buy throughout the year on a competitively bid basis.”

With this lower PGA, a typical residential customer’s bill using 35 Ccf that was $49.36 in July will be $43.33 beginning in August, excluding taxes. This represents a 12.2 percent decrease. For typical winter usage of 100 Ccf, a customer’s bill will be $104.29 this winter compared to $134.64 last winter, excluding taxes, a 22.5 percent decrease.

The company also filed to change the base rates that the company charges customers for natural gas utility service. The proposed annual revenue increase is $25.4 million. The base rate portion of a customer’s natural gas bill, which makes up about 30-40 percent of the total bill, covers the cost of distributing natural gas. The overall average increase for a residential customer using 35 Ccf is $4.09 per month and represents an 8.3 percent increase in the total residential bill, excluding taxes.

“We are proposing to change the base rate portion of the bill because the cost of distributing natural gas to our customers, such as labor, materials and supplies, and other operating expenses, has continued to increase while usage has declined. The ability to earn a reasonable return on investment is critical to our ability to continue to build our system to support future economic development,” he added.

While the lower PGA goes into effect in August, CenterPoint Energy expects the new base rates would go into effect in the first quarter of 2010.
