British Firms Among Finalists Vying for Platts Global Energy Awards

Winners to be Announced at December 2 New York Event

NEW YORK, October 1, 2010 - Three British energy firms are among the companies from 21 countries on
three continents that have been chosen as finalists in the Platts Global
Energy Awards, an annual program recognizing exemplary industry leadership.
The 2010 finalists, selected from well over 200 nominations, were announced
this week by program host Platts, the leading global provider of energy
information.

Established in 1999 and widely recognized as the "Oscars" of the energy
industry, Platts Global Energy Awards highlight corporate and individual
innovation, leadership, and superior performance in 17 categories spanning
the entire energy complex.

Two British firms are on the short list for energy efficiency awards:
Tesco plc is one of nine finalists for Energy Efficiency Program of the Year
- Commercial End-User and National Grid is one of eight finalists for Energy
Efficiency Program of the Year - Energy Supplier. Aquamarine Power is one of
12 finalists for Sustainable Technology Innovation of the Year.

"This year's record number of entries and finalists in the energy
efficiency and technology categories underscores the industry's increasing
commitment to developing environmentally-conscious solutions to the world's
supply needs," said Larry Neal, president of Platts. "We look forward to
spotlighting our finalists' accomplishments in these categories and all
others when we unveil the Global Energy Awards winners in December."

In addition to the awards in the specific performance categories, Platts
will also name the 2010 Energy Company of the Year. The winner of this award
will be chosen from the entire list of finalists by the program's independent
judges' panel, which includes former regulators, past heads of major energy
companies, leading academics and international energy experts.

More than 500 guests are expected to attend the black-tie dinner at New
York's Cipriani Wall Street on Thursday, December 2, when the 2010 Global
Energy Awards will be presented by Platts and Capgemini, the program's
principal sponsor for the past eight years.

The awards event will be preceded on December 1 with an associated event,
Platts Global Energy Outlook Forum, an industry debate on the topic of "Clean
Energy: Fact or Fiction?"
