             South Carolina Regulators Approve Duke-Cinergy Merger


CHARLOTTE, N.C. - The Public Service Commission of South Carolina (PSCSC) has
unanimously approved Duke Energy's planned merger with Cinergy, the company
announced today.

In approving the planned combination, the PSCSC signed off on proposals
submitted in early October by Duke Energy and other parties, to resolve all
issues related to the commission's merger review.

"Today's action in South Carolina is an important milestone as we move forward
with the Duke Energy-Cinergy merger," said Ellen Ruff, group vice president of
planning and external relations at Duke Power. "This merger is about building
a stronger company with the size and strength to continue delivering reliable
electric service to our customers at a cost well below the national average."

"The agreements approved by the commission ensure Duke Power customers will
share in the value that is created by this merger," Ruff continued. "This is
truly a win-win, reinforcing Duke Energy's long-standing commitment to its
customers in the Upstate of South Carolina."

Key aspects of the agreement with the Office of Regulatory Staff, the South
Carolina Energy Users Committee and Duke Energy include:

o    $40 million rate reduction for one year. The agreement calls for a $40
     million reduction of retail base rates to Duke Power's S.C. customers.
     The rate reduction - which represents a 4 percent rate reduction, on
     average, across all customer classes -- would flow through a rate
     decrement rider to existing base rates for a one-year period following
     the close of the merger. Duke Energy expects to amortize the $40 million
     over a five-year period.
o    Three-year extension for bulk power marketing (BPM) profit sharing. The
     agreement extends for three years, through the end of 2010, Duke Power's
     non-firm BPM profit-sharing agreement in South Carolina. Duke Power's BPM
     division sells the company's temporary excess electricity to municipal,
     cooperative and investor-owned utilities and other wholesale customers.
The PSCSC also approved an agreement with the Electric Cooperatives of South
Carolina Inc., Central Electric Power Cooperative Inc., Saluda River Electric
Cooperative Inc. and Duke Energy, which calls for additional transmission
planning activities to be developed in the state.

With PSCSC approval, South Carolina becomes the first state to approve the
merger, announced on May 9, 2005. State regulators in Ohio, Indiana, Kentucky
and North Carolina are also reviewing the planned combination, which remains
subject to other closing requirements, including approvals from various
federal regulatory agencies, and shareholders of both Duke Energy and Cinergy.

In August, the companies satisfied Federal Trade Commission and U.S.
Department of Justice review under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976. The companies anticipate receiving all necessary
approvals by the first half of 2006.

Duke Power, a business unit of Duke Energy, is one of the nation's largest
electric utilities and provides safe, reliable, competitively priced
electricity and value-added products and services to more than 2 million
customers in North Carolina and
