Bryn Posteg Landfill Gas site signs new supply contract

Renewable Energy Holdings plc
("REH" or "the Company")
Renewable Energy Holdings plc (AIM: REH), the AIM quoted investor and operator of proven and innovative renewable energy technologies, is pleased to announce that Gwynt Cymru Limited, a wholly owned subsidiary of the Company and the operator of the Bryn Posteg landfill gas site in Wales, has signed a new Power Purchase Agreement ("PPA") with EDF Energy.

The current PPA will expire on 30 November 2007. The new contract with EDF Energy secures a significantly higher unit price for the next 16 months. The higher unit price, in conjunction with new initiatives being implemented to increase production levels at Bryn Posteg from current output of 1MW, means that Gwynt Cymru Limited is expected to generate considerably increased revenues in 2008.

Commenting on the new PPA, Mike Proffitt, Chief Executive of REH said: �We acquired this asset in the certain knowledge that we could increase the gas production, and renew the then existing PPA with a much higher price. This new PPA more than doubles the old price and the resultant revenue increase will flow to the bottom line 100%.�

renewable energy technologies.

� REH owns two operational wind farm sites is Germany. Kesfeld (32.5MW) and Kirf
(8MW). In addition, REH is at various stages of development of further wind
farm sites in Poland and Wales.

� REH owns a 1MW methane Landfill Gas Project in Powys, Wales. The long-term

ocean forces, and self contained. Unlike other wave energy technologies that
require undersea grids and costly marine qualified plant, CETO requires only a
small diameter pipe to carry high pressure seawater ashore to either a turbine
to produce electricity, or to a reverse osmosis filter to produce fresh water.

� The Directors and executive team of REH have extensive experience in both the
conventional and renewable energy sectors, both in the UK and overseas, and
through their experience have built a broad international network of
relationships with individuals, companies, governments and lobby groups.
