EuroSite Power Appoints Adrian Fawcett

LONDON, October 4, 2011 -

EuroSite Power Limited (www.eurositepower.co.uk), a subsidiary of NYSE Amex-listed American DG Energy Inc., is pleased to announce the appointment of Adrian Fawcett as Chairman of its Advisory Board.  

Adrian Fawcett has extensive experience in the leisure and healthcare sectors, that will be of enormous value to EuroSite Power.  The Company launched in the UK earlier this month in order to offer its On-Site Utility service to customers principally in the hospitality, healthcare and housing markets, that have a year round requirement for heat energy.  EuroSite Power’s On-Site Utility can reduce energy costs and measurably reduce a user’s carbon footprint.

Adrian has been Chief Executive Officer of General Healthcare Group, the UK’s largest independent healthcare business, for the last four years and was also Chairman of the Real Pub Company that was recently sold to Green King Plc.  Prior to this Adrian was Chief Operating Officer at Punch Taverns plc, turning it into a FTSE 100 company with over 9,000 pubs.  Before that he was at Bass Brewers Plc, the UK’s number one brewery.

Adrian is currently the Chairman of Silent Night Group, the UK’s largest bed manufacturer, a company with strong environmental and sustainability credentials, as well as being a Non Executive Director of the Department of Work and Pensions from 2006 through to the current year.

Paul Hamblyn, Managing Director of EuroSite Power commented:

“We are delighted to welcome Adrian Fawcett to the Advisory Board of EuroSite Power as its Chairman.  Adrian has a long career in British business and is hugely supportive of EuroSite Power’s On-Site Utility solution, recognising the benefits it can offer to our users in terms of energy and cost savings, alongside a reduced carbon footprint.  He brings a wealth of experience and knowledge of key market sectors, notably healthcare and leisure, that are core to EuroSite Power’s customer base.  This will be invaluable as the Company seeks to broaden awareness of its unique On-Site Utility solution.”

Adrian Fawcett commented:

“I am pleased to have been invited to join the EuroSite Power Advisory Board and look forward to working with the team to bring about both the benefits of its proven Combined Heat and Power technology as well as some innovative solutions to the Company’s future customers.  We all have a responsibility to think about establishing efficiency and sustainability in our business, work and home lives and I think this Company’s proposition can be part of that in many settings.

“I have always been excited about helping business ventures establish exciting operational platforms - and EuroSite Power is one that has all the ingredients to challenge the energy efficiency solutions market.”
