Burlington, VT and Worcester, MA April 30, 2009 World Energy Solutions, Inc. (NASDAQ: XWES; TSX: XWE), an operator of online exchanges for energy and green commodities, today announced Burlington Electric Department (BED) has successfully brought to market, and sold, CT Class I Renewable Energy Certificates (RECs) on the World Green Exchange®. BED produces a significant number of CT Class I RECs annually through a wood-fired facility in Burlington, Vermont. The RECs have been sold on behalf of BED and the other joint owners of the facility: Central Vermont Public Service, Green Mountain Power, and VPPSA.The successful transactions, in which multiple bidders were awarded RECs, have set the stage for future REC sales events, including one planned for later in May. Prior to engaging with World Energy, BED sold its RECs through various brokers, but it was looking for additional methods to bring its clean-energy assets to market. Using the World Green Exchange has enabled BED to solicit the interest of multiple bidders, test pricing, and come to contract terms quickly with buyers. At BED the creation and sale of RECs are an important part of our clean energy strategy, so finding effective ways to bring these assets to market is a priority, said Ken Nolan, Director of Resource Planning at BED. Posting our RECs on the World Green Exchange is helping us build a dialogue with interested buyers while also making it easier for us to transact with confidence. We like the transparency we are gaining with this system and the momentum we are building with buyers in advance of future postings.Phil Adams, President of World Energy, added, RECs are an important part of how utilities and retail energy providers comply with renewable portfolio standards, yet the REC market remains illiquid and opaque. The REC market needs to provide buyers and sellers more transparency if it is to become a mainstay of how business is done. That is the spirit informing every aspect of the World Green Exchange, and we are happy to be attracting companies of BED s caliber to our platform and helping them achieve positive results.The World Green Exchange® is an open, information-rich marketplace that enables buyers and sellers of carbon commodities to transact with confidence. Working with leading standards, registries, consultants, project developers and banks, the World Green Exchange streamlines the procurement process while delivering transparency, quality, choice and value. More than 78 million green commodities, spanning CERs, VERs, RECs, Alberta offsets and RGGI allowances, have been transacted on the World Green Exchange, making it one of the largest primary carbon marketplaces in the world.
