                   BP ALTERNATIVE ENERGY BUYS US WIND COMPANY


BP announced today that it has purchased Greenlight Energy, Inc., a US-based
developer of wind power generation projects. The purchase will allow BP to
accelerate its plans to develop a leading wind power business in North America.

BP has acquired all the shares of Greenlight Energy for a consideration of some
$98 million, excluding working capital and tax adjustments.

Greenlight is a developer of large-scale wind energy projects across the USA.
Founded in 2000 and based in Charlottesville, Virginia, the company has a
portfolio of some 39 mature and early stage development projects across the USA
with a potential total power generating capacity of 6.5GW. This portfolio
contains a number of projects which BP expects to be able to develop over the
next five years.

The purchase will further accelerate the rapid growth of BP's US wind power
business, a key part of BP Alternative Energy, the company's low-carbon power
generation business. In July, BP Alternative Energy announced it had reached
agreement with the wind project developer and turbine manufacturer Clipper
Windpower to acquire a 50 per cent stake in a 2GW wind development portfolio in
the USA as well as an agreement for the supply of turbines with a generating
capacity of up to 2.25GW over the next five years.

'This purchase gives BP Alternative Energy immediate access to a large number of
high quality wind development projects across the country, including a number of
projects we expect to be able to develop over the next few years,' said Steve
Westwell, chief executive of BP Alternative Energy. 'We look forward to working
closely with the Greenlight team, who have built the company over the past six
years.'

'Greenlight went through a rigorous process to find a strategic partner that
would enable the company to accelerate the development of projects in our
pipeline,' said Matthew Hantzmon, Managing Director of Greenlight Energy. 'The
strategic mandate of BP Alternative Energy is a perfect fit to scale up our
business and enable the build-out of Greenlight's portfolio.'


Notes to editors:

• Greenlight Energy is a developer of large wind energy projects in the
  United States. The company's portfolio is comprised of large scale projects,
  spread widely across the USA. The company's strategy has been to invest in new
  projects at the earliest possible stage and to advance them through to
  successful construction and operation. It has successfully developed and sold
  individual development projects to larger industry players.

• BP Alternative Energy, launched in November 2005, combines all of BP's
  interests in zero- and low-carbon power generation: wind, solar, hydrogen 
  power projects and gas-fired power generation. BP expects to rapidly grow BP
  Alternative Energy to become a material contributor to the company's 
  performance and anticipates investing up to $8 billion in the businesses over 
  the next ten years.
