Public Utilities Commission of Ohio Approves Cinergy/Duke Merger

CINCINNATI – Cinergy Corp. (NYSE:CIN) announced today that the Public Utilities Commission of Ohio has approved an agreement resolving all issues related to the Commission’s review of the company’s planned merger with Duke Energy.

“With the approval today, Ohio becomes the third state to recognize the benefits for all stakeholders from the combination of Duke and Cinergy,” said Greg Ficke, president of The Cincinnati Gas & Electric Co., Cinergy’s Ohio operating company. “Our focus now is to continue to provide the service quality and reasonable prices our customers have come to expect.”

Key elements of the agreement include:

• $20.6 million merger savings rate credit. Cinergy/CG&E will credit to its gas and electric customers in Ohio a total of approximately $20.6 million in the first year following the closing of the merger. Electric distribution customers will receive a credit of approximately $16.4 million and gas distribution customers approximately $4.2 million. 
• $15.2 million rate stabilization credit. Beginning January 1, 2006, Cinergy/CG&E will provide a rate credit of approximately $15.2 million for one year to mitigate increases from its pending electric distribution rate application and its rate stabilization plan.
• Guaranteed income tax payments and charitable support. Cinergy/CG&E will guarantee that the City of Cincinnati will receive no less than $11.79 million in personal income tax revenue from 2006 through 2008, as well as corporate income tax and franchise fee payments of at least $1.5 million per year during the three-year period. It will also provide a contribution to the City to encourage economic development and other priorities. Additionally, minimum annual charitable contributions in the Cinergy utility service areas in 2007-2008 will be no less than the annual average contributions of approximately $5 million in 2004-2005.

As part of the agreement, Cinergy/CG&E provided a list of merger commitments designed to protect its customers from adverse impacts in retail customer service, customer satisfaction and reliability in achieving merger savings.  Retail rates will not be impacted by the costs associated with the new Duke Energy acquiring Cinergy stock or any premium paid in the acquisition.

The agreement was reached with the City of Cincinnati, Interstate Gas Supply, Kroger Company, Ohio Energy Group and Buckeye Association of School Administrators, Ohio Association of School Business Officials and the Ohio School Board Association.

In other action, the PUCO also approved an agreement on CG&E’s first increase in rates for Ohio electric distribution service in more than 10 years.  The increase of $51.5 million, or approximately four percent in annual revenues, will take effect in January 2006.

The agreement recognizes in rates the investment of $734 million by CG&E over the last 12 years to improve the reliability of its electric delivery system. It also reflects increases in electric transmission costs from the Midwest Independent System Operator, as approved by the Federal Energy Regulatory Commission and the PUCO. 

Coupled with an increase in the generation rate approved last year under CG&E’s rate stabilization plan, a typical residential customer using 1,000 kilowatthours a month would see an increase in their total bill from the current $79.64 per month to $105.53. The merger rate credits approved today will reduce the increase by $1.32 on January 1, 2006 and an additional $1.42 after the merger closes.    

Cinergy/CG&E serves approximately 650,000 customers in Southwest Ohio and is an affiliate of Cinergy Corp. (NYSE:CIN), which has a balanced, integrated portfolio consisting of two core businesses: regulated operations and commercial businesses. Cinergy’s regulated public utilities in Ohio, Indiana, and Kentucky serve 1.5 million electric customers and about 500,000 gas customers. In addition, its Indiana regulated company owns 7,000 megawatts of generation. Cinergy’s competitive commercial businesses have 6,300 megawatts of generating capacity with a profitable balance of stable existing customer portfolios, new customer origination, marketing and trading, and industrial-site cogeneration. Cinergy’s integrated businesses make it a Midwest leader in providing both low-cost generation and reliable electric and gas service.
