  • Dr David Williams
  • Dr David Williams
  • Director
    David is a graduate Chartered Electrical Engineer who also holds qualifications in Management, Accountancy and Finance. He has been involved in renewable energy for over 20 years, and has been a TEL Director since 2007.

    Following 19 years with the utility company SWALEC he started Energy Power Resources Ltd (EPRL) in 1996 and shortly afterwards undertook a £25 million private placement.  This was the UK’s largest private placement in renewable energy. The target set by the venture capitalists was to create the UK’s largest renewable energy company, generating over a 100MW of base load capacity from biomass within three years.  He was Chief Executive of EPRL until February 2002 by which time EPRL had achieved its growth targets.

    David co-founded Eco2 Ltd in November 2002 and led negotiations on a £100m funding deal with Good Energies (UK) LLP and the Bank of Tokyo Mitsubishi UFJ to build a Wind Farm in Scotland, Wales’ first commercial scale Biomass project and a number of other Wind Farm projects. In December 2011 David also managed the negotiations on the sale of Eco2’s 40MW straw-powered biomass plant in Sleaford, Lincolnshire to specialist investment fund BNP Paribas Clean Energy Partners, in a landmark £170m deal. He is now leading a business plan to develop over £1.7billion of Biomass projects throughout Europe.

    David was previously an Independent Grant Assessor for the DTI, a member of the government's Renewables Advisory Board and has also been a member of the DEFRA Biomass Implementation Advisory Group. He is currently a Non-Executive Director to Temporis Capital, in respect of its Ventus funds, a member of DECC’s Biomass Sustainability Group, a REA Board Member and chairs the REA Biomass Power Group.

    David is Chair of the Welsh Government’s Energy & Environment Sector Panel and was awarded an Honorary Doctorate in recognition of his outstanding contribution to renewable energy by the University of South Wales, in 2013.

    Projects developed by David during his career now supply renewable energy to over 1.1m homes and save over 3.25m tonnes per annum of CO2, representing a CO2 saving equating to 11% of the entire target set by the last government for 2010.

    David won the Champion Award - given in respect of a lifetime's achievements in renewable energy - at the Renewable Energy Association's Awards in June 2007, the Institute of Welsh Affairs Inspire Wales Environmentalist Award in June 2011, the Energy Institute's prestigious Individual Achievement Award in November 2011, the Entrepreneurial Leadership (Private Sector) Award at the Leading Wales Awards in May 2012 and the Renewables and Cleantech category for the London and South Region, at the Ernst & Young UK Entrepreneur of the Year Awards, in June 2012.  In July 2013, David was awarded an Honorary Doctorate in recognition of his outstanding contribution to renewable energy by the University of South Wales.
