Winnisquam Biofuels Project - Interview and Walk Through

The Winnisquam School District installed a biofuels heating system for two schools and their SAU – School District Offices. This video is a description of that project and includes an interview with Ian Raymond who spearheaded the project and a walk through of the biofuels plant. Winnisquam School District Energy Project Results after 7 years operation. Five years after the above video was made, I interviewed Ian Raymond again about the results of the Biofuels plant installation and a series of energy efficiency measures which were also installed at the same time. One source of funding for this  project was a PERFORMANCE CONTRACT  Under this arrangement, an energy service company does an energy audit, proposes specific efficiency measures, and then GUARANTEES the savings which are then used to pay off the project. These are the measures that were completed by Honeywell and guaranteed by the performance contract. Though some of the funding mechanisms mentioned in this video are no longer available, others still are, and performance contracting can still be an effective way of funding energy projects.
