                 Duke Energy Reports First Quarter 2006 Results

      o     Ongoing diluted earnings per share (EPS) of 48 cents versus 43 cents
            in prior year's quarter; reported diluted earnings per share of 37
            cents versus 88 cents in previous year's quarter

      o     Improved results at Franchised Electric, Natural Gas Transmission
            and International Energy

      o     On track for annual employee incentive target of $1.90 per ongoing
            diluted share

      o     Cinergy Corp. - results not included in Duke Energy earnings - posts
            ongoing diluted EPS of 62 cents versus 60 cents in prior year's
            quarter; first quarter 2006 reported diluted EPS of 39 cents versus
            60 cents in previous year's quarter

CHARLOTTE, N.C. - Duke Energy today posted ongoing diluted earnings per share
(EPS) for first quarter 2006, which excludes special items and discontinued
operations (with the exception of Crescent Resources), of 48 cents, versus 43
cents in first quarter 2005.

The company reported first quarter 2006 diluted EPS of 37 cents, or $358 million
in net income, compared to 88 cents per diluted share in first quarter 2005, or
$868 million in net income. Revenues for first quarter 2006 were $3.2 billion,
compared to $5.3 billion in the previous year. The lower revenues were driven by
the deconsolidation of Duke Energy Field Services (DEFS) following the transfer
of a 19.7 percent interest in DEFS from Duke Energy to ConocoPhillips.


                                     - 1 -


Also today, Cinergy Corp., which operated separately from Duke Energy in first
quarter, posted first quarter 2006 ongoing earnings of 62 cents per diluted
share, absent discontinued operations and special items, consistent with Duke
Energy's definition, compared to 60 cents from the previous year's quarter.
Reported diluted earnings for first quarter 2006 were 39 cents, compared to 60
cents from first quarter 2005.

Duke Energy and Cinergy completed their merger on April 3, 2006, and will report
combined results going forward. However, for first quarter 2006, results are not
combined; and going forward, Cinergy's first quarter results will not be
included in Duke Energy's 2006 earnings.

"Despite near record mild winter weather, our electric and gas operations
delivered solid performances this quarter," said James E. Rogers, president and
chief executive officer of Duke Energy.

"As we combine the Duke Energy and Cinergy businesses beginning in second
quarter, we're comfortable we will be able to achieve our 2006 employee
incentive target of $1.90 per share," added Rogers. That target should track
ongoing diluted earnings per share. "Our combined portfolio of businesses
provides us an outstanding platform to deliver positive results to our
shareholders."

BUSINESS UNIT RESULTS

Franchised Electric

First quarter 2006 segment EBIT for Franchised Electric was $359 million,
compared to $336 million in the prior year's quarter. The increase was driven
primarily by improved bulk power marketing results, customer growth and lower
regulatory amortization. This increase in segment EBIT was partially offset by
mild winter weather - with January 2006 being the second warmest on record in
North Carolina and South Carolina. Regional growth continued to add to
Franchised Electric's total customer base, with 41,000 customers - about 2
percent - being added during the past year.

Natural Gas Transmission

Duke Energy Gas Transmission (DEGT) reported first quarter 2006 segment EBIT of
$438 million, compared to $411 million in first quarter 2005. The increase was
primarily due to $24 million received from the settlement of a customer's
transportation contracts.


                                     - 3 -


Absent the special item noted above, ongoing EBIT for first quarter 2006 was
$414 million, compared to $411 million in the previous year's quarter. Business
expansion, natural gas processing and the impact of a strengthening Canadian
currency were offset by higher operating costs, lower margins at Union Gas due
to record warm weather and lower equity earnings related to interest expense.

The favorable Canadian currency impacts on DEGT's EBIT were partially offset in
Duke Energy's consolidated net income by currency impacts on Canadian interest
and taxes.

Field Services

The Field Services business segment, which represents Duke Energy's 50 percent
interest in Duke Energy Field Services (DEFS), reported first quarter 2006
equity earnings of $144 million, compared to $919 million of segment EBIT from
continuing operations in first quarter 2005.

The previous year's EBIT included $770 million in special items concerning the
gain on the sale of the TEPPCO GP and the TEPPCO L.P. units and the loss on the
2005 de-designated hedges. In the current quarter, Field Services recognized
equity earnings of $14 million related to its share of a DEFS sale of natural
gas gathering and processing assets in southeast Texas and Louisiana.

Absent the special items noted above, Field Services reported ongoing equity
earnings for first quarter 2006 of $130 million, compared to ongoing segment
EBIT of $149 million in the previous year's quarter.

Ongoing results were driven by Duke Energy's reduced ownership interest in DEFS,
plus higher operating costs - primarily repairs and maintenance. These were
partially offset by strong commodity prices and gas marketing results.

During the quarter, DEFS paid tax distributions of about $93 million to Duke
Energy.


                                     - 4 -


International Energy

For first quarter 2006, Duke Energy International (DEI) reported segment EBIT
from continuing operations of $87 million, compared to $68 million in first
quarter 2005. The positive results were driven by improved prices and volumes in
the Latin America operations, favorable currency impacts - mainly in Brazil -
and increased margins at National Methanol.

During the quarter, DEI closed on two transactions which increased its ownership
in the Aguaytia Integrated Energy Project in Peru to 64.9 percent.

Crescent Resources

Crescent Resources reported first quarter 2006 segment EBIT from continuing
operations of $42 million, compared to $52 million in the previous year's
quarter. The key driver was lower legacy land sales in first quarter 2006,
compared to last year's first quarter.

Other

Other primarily includes the cost of corporate governance, Duke Energy's captive
insurance company, Bison Insurance Co. Limited, de-designated hedges resulting
from the decision in 2005 to transfer a 19.7 percent interest in DEFS to
ConocoPhillips, and Duke Energy North America's (DENA) continuing operations.
Other reported an EBIT loss of $85 million in first quarter 2006, compared to a
loss of $202 million in first quarter 2005.

Other's first quarter 2005 EBIT included a $54 million EBIT loss on the
de-designated 2005 hedges at DEFS and a $28 million liability adjustment at
Bison. In the current quarter, Other's EBIT included approximately $5 million in
merger-related costs. Absent the special items, ongoing first quarter 2006 EBIT
loss for Other was $80 million, compared to an ongoing loss of $120 million in
the previous year's quarter.


                                     - 5 -


The improved results were driven largely by lower losses from mark-to-market
movement in the de-designated hedges and lower losses associated with DENA's
continuing operations. For the quarter, DENA's continuing operations posted a
loss of $23 million in EBIT, compared to a $33 million EBIT loss in first
quarter 2005.

Discontinued Operations

In first quarter 2006, Discontinued Operations had a loss of $128 million,
compared to a first quarter 2005 gain of $8 million. The results were driven by
the losses on certain contract terminations at DENA and a charge associated with
DEI's sale of its European operations to Norsk Hydro.

INTEREST EXPENSE

Interest expense was $250 million for first quarter 2006, compared to $290
million for first quarter 2005. The decrease was driven largely by the transfer
of a 19.7 percent interest in DEFS from Duke Energy to ConocoPhillips, resulting
in the deconsolidation of this investment by Duke Energy.

INCOME TAX

First quarter 2006 income tax expenses from continuing operations were $258
million, compared to $451 million in first quarter 2005. The decrease was driven
primarily by higher pre-tax earnings in 2005 resulting from the gains on the
sales of TEPPCO GP and TEPPCO L.P.

LIQUIDITY AND CAPITAL RESOURCES

Duke Energy's consolidated capital structure at the end of first quarter 2006,
including short-term debt, was 48 percent debt, 50 percent common equity and 2
percent minority interests. The company had approximately $817 million in cash,
cash equivalents and short-term investments as of March 31, 2006.


                                     - 6 -


CINERGY CORP.

For first quarter 2006, Cinergy Corp. posted ongoing earnings of 62 cents per
diluted share, absent discontinued operations and special items, consistent with
Duke Energy's definition, compared to 60 cents from first quarter 2005. Reported
diluted earnings for first quarter 2006 were 39 cents per share, compared to 60
cents from the previous year's quarter.

Ongoing earnings were helped by revenue increases related to the Ohio rate
stabilization plan and other base rate increases, as well as optimization and
trading and marketing. This was partially offset by milder weather, fewer tax
credits at the company's synfuel facilities and higher operating and maintenance
expenses in the regulated business unit.

Mark-to-market movements for optimization and trading and marketing are included
in ongoing earnings - consistent with Duke Energy's historical practice.
Previously, Cinergy had excluded mark-to-market movements associated with gas,
fuel and power contracts that hedge gas storage and generation assets from
adjusted earnings (see accompanying supplemental information).

NON-GAAP FINANCIAL MEASURES

The primary performance measure used by management to evaluate segment
performance is segment EBIT from continuing operations, which at the segment
level represents all profits from continuing operations (both operating and
non-operating), including any equity in earnings of unconsolidated affiliates,
before


                                     - 7 -


deducting interest and taxes, and is net of the minority interest expense
related to those profits. Management believes segment EBIT from continuing
operations, which is the GAAP measure used to report segment results, is a good
indicator of each segment's operating performance as it represents the results
of our ownership interests in continuing operations without regard to financing
methods or capital structures.

Duke Energy's management uses ongoing diluted EPS, which is a non-GAAP financial
measure as it represents diluted EPS from continuing operations plus any
discontinued operations from its Crescent Resources real estate unit, adjusted
for the impact of special items, as a measure to evaluate operations of the
company. Special items represent certain charges and credits which management
believes will not be recurring on a regular basis. The amount presented as
ongoing earnings for Cinergy Corporation represents reported diluted EPS
adjusted for special items as defined by Duke Energy. Management believes that
the presentation of ongoing diluted EPS provides useful information to
investors, as it allows them to more accurately compare the company's ongoing
performance across periods. In 2006, ongoing diluted EPS will be used as the
basis for employee incentive bonuses. The most directly comparable GAAP measure
for ongoing diluted EPS is reported diluted EPS from continuing operations,
which includes the impact of special items. Due to the forward-looking nature of
ongoing diluted EPS for future periods, information to reconcile such non-GAAP
financial measures to the most directly comparable GAAP financial measure is not
available at this time as the company is unable to forecast any special items
for future periods.

Duke Energy also uses ongoing segment (including ongoing equity earnings for
Field Services) and Other EBIT as a measure of historical and anticipated future
segment performance. When used for future periods, ongoing segment and Other
EBIT may also include any amounts that may be reported as discontinued
operations. Ongoing segment and Other EBIT are non-GAAP financial measures as
they may represent reported segment and Other EBIT adjusted for special items.
Management believes that the presentation of ongoing segment and Other EBIT


                                     - 8 -


provides useful information to investors, as it allows them to more accurately
compare a segment's or Other's ongoing performance across all periods. The most
directly comparable GAAP measure for ongoing segment or Other EBIT is reported
segment or Other EBIT, which represents EBIT from continuing operations,
including any special items. Due to the forward-looking nature of forecasted
ongoing segment and Other EBIT and related growth rates for future periods,
information to reconcile these non-GAAP financial measures to the most directly
comparable GAAP financial measures is not available at this time as the company
is unable to forecast any special items or any amounts that may be reported as
discontinued operations for future periods.

Prior to the merger, Cinergy's management used adjusted earnings, which is a
non-GAAP financial measure as it represents reported earnings, adjusted for
items not related to Cinergy's ongoing, underlying business or which distort
comparability of results, as a measure to evaluate operations of the company.
Cinergy's management used adjusted earnings internally for analysis of
performance and for reporting results to its board of directors, and considered
this measure to provide a meaningful representation of Cinergy's fundamental
earnings power.
