BILBAO,  Spain and PORTLAND,  Maine, June 25, 2007: The Boards of IBERDROLA S.A.
and Energy East Corporation  (NYSE:  EAS), meeting today in Madrid and New York,
respectively,  have  approved a merger  agreement  under  which  IBERDROLA  will
acquire 100% of Energy East, which will become part of the IBERDROLA group.

According to the terms of the merger agreement,  the shareholders of Energy East
would  receive  $28.50 in cash per share at closing,  representing  a premium of
20.2% over  Energy  East's  average  closing  stock  price for the 30 day period
ending June 22, 2007 (27.4% over Energy  East's  closing stock price on June 22,
2007).

The transaction  values Energy East at  approximately  6,400 million euros ($8.6
billion) in terms of enterprise value (market equity value plus net debt).

IBERDROLA will analyze different financing alternatives for the transaction and
will select the one which best meets its requirements from the point of view of
maintaining its financial solidity and ratings.

The transaction is subject to approval by the shareholders of Energy East,
Federal and State authorizations, and other customary closing conditions and is
expected to close in 2008.

     million in the UK).




IBERDROLA  Chairman and CEO,  Ignacio Galan said, "The  combination  with Energy
East fits with the philosophy of our Strategic  Plan,  will serve to enhance the
international  expansion we initiated  several  years ago in markets with stable
growth, and consolidates our position as one of the world's leading  electricity
companies."

Galan said "the  acquisition  of Energy East will allow  IBERDROLA to strengthen
its  commitment  to  shareholders,   improving  Group  results,   dividends  and
profitability.  It will  also  enhance  our  commitment  to  customers,  through
improved  quality  of  supply,  and  to  society,  contributing  to  sustainable
development  thanks to our world leadership in renewable energy and to increased
investments devoted to reducing emissions.

"This new step in the United  States will allow  IBERDROLA  to continue  working
with national and State governments to make investments in  infrastructure  that
advance  clean energy  policies;  we welcome  Energy  East's  employees and look
forward  to  leveraging  our  experience  to  help  address  some  of  the  most
challenging  energy and environmental  issues in the Northeastern US," concluded
Galan.

"This  transaction is a unique  opportunity to deliver  enhanced value to Energy
East's  shareholders  and to build a stronger future for our company,  employees
and the states we serve,"  said Wes von  Schack,  Chairman  and Chief  Executive
Officer of Energy East.

"The energy  industry is at a major  inflection  point,"  continued  von Schack.
"Policymakers  now  recognize  the need  for our  industry  to make  significant
investments  in our energy  infrastructure.  Our  objective  is to team with the
States in which we do business to help meet the goals they have  established  to
increase renewable sources of energy, improve energy efficiency, and invest in a
secure and  reliable  energy  infrastructure.  We believe our  combination  with
IBERDROLA will not only accelerate our progress but will transform the way we do
business."

"Furthermore,  while  IBERDROLA is a global energy  company,  its operations are
managed locally.  I'm therefore  delighted to assure Energy East's three million
customers  that they can  continue to rely on the same local people whom they've
come to know and trust to provide  exceptional  customer service," concluded von
Schack.



IBERDROLA's expertise and track record in all aspects of delivering sustainable,
clean energy make it a strong  partner to help support and advance Energy East's
efforts. In particular, IBERDROLA has made almost $4 billion in transmission and
distribution investments over the past three(2) years and has been successful in
initiatives  that  have  reduced  customer  demand  and  peak  consumption.  Its
significant  engineering and construction resources place it at the leading edge
of environmental technologies.

IBERDROLA expects to support Energy East's efforts by exploring opportunities to
expand its wind generation portfolio,  which includes the upstate New York-based
Maple Ridge wind  generating  facility - the largest  such  facility on the East
Coast.  As a  leading  developer  of  natural  gas  combined  cycle  generation,
IBERDROLA  will also bring  construction  expertise  to Energy  East's  plans to
repower the Russell generating station.

A New Step in IBERDROLA's Internationalization Strategy

Energy  East is a US-based  utility  company  listed on the NYSE,  with a strong
presence in  electricity  (1.8 million  customers)  and natural gas (0.9 million
customers) regulated businesses.

The company  focuses the majority of its  activities  in four states on the East
Coast  of the  US,  and is  nationally  recognized  for its  excellent  customer
satisfaction, reliability and environmental stewardship.

This  transaction  allows  IBERDROLA  to  increase  its  presence  in the US and
accelerates  the  achievement  of  the  internationalization  objective  set  in
IBERDROLA's Strategic Plan approved last October.

Energy East represents the right platform for  IBERDROLA's  future growth in the
US.

A Global Company with a Commitment to Local Operations

Following the close of the transaction,  Energy East's utility subsidiaries will
continue to operate  under  their  current  names (The  Berkshire  Gas  Company,
Central Maine Power Company, Connecticut Natural Gas Corporation, New York State
Electric & Gas  Corporation,  Rochester  Gas and Electric  Corporation,  and The
Southern Connecticut Gas Company).

The Enhancement of a Leading Global Utility

The  integration of IBERDROLA and  ScottishPower,  in April 2007,  represented a
milestone  for the one hundred  year-old  IBERDROLA,  creating a leading  global
utility and a world leader in renewable energies.

With the Energy East transaction, the enterprise value of IBERDROLA will surpass
83,000 million euros, ($112 billion) at today's values consolidating the company
as one of the world's largest electricity operators.

the transaction,  will have 24 million electricity points of supply, 3.0 million

IBERDROLA  continues its strategic support for renewable  energies,  where it is
the world  leader.  Globally,  IBERDROLA  has 16,500 MW of  installed  renewable
energy capacity (including large-scale hydro), and the company expects to exceed
20,000 MW in the coming years. The transaction also allows IBERDROLA to optimize
its current  presence  in the  renewable  energy  business in the US, the second
largest market globally.

In addition, IBERDROLA has 2.7 bcm of gas storage capacity in the UK and the US,
having significant opportunities to expand this business.
