US-based distributed generation company Sustainable Energy Developments (SED) has completed the installation of a 600 kW wind turbine to supply power to the Williams Stone Company, East Otis, Massachusetts, US.
Construction of the 600 kW Vestas RRB wind turbine started in November 2008 and was completed at the end of May. Williams Stone Company was officially powered by wind less than a week later, after commissioning and interconnection was complete. The project cost $1.7 million and, with an estimated annual savings of $172,000, is expected to pay for itself in six to eight years.
SED’s first step was to apply for a design and construction grant from the Massachusetts Technology Collaborative (MTC). The MTC, now the Massachusetts Renewable Energy Trust (MRET) awarded the granite company with a grant in the amount of $500,000 that allowed SED to begin design tasks for the project.
‘Industrial companies, like Williams Stone, are one of the country’s most energy intensive sectors which will be heavily relied upon to rebuild our economy,’ said Kevin Schulte, CEO of SED. ‘This is and will continue to be a successful project model because it combines an energy-intensive manufacturer with clean renewable energy technology. There are similar facilities in windy locations across the nation and we hope to bring wind power to all of them.’
Williams Stone Company is the fifth utility-scale, on-site wind project that SED has installed in Massachusetts. Others are located at a ski resort, several schools and business premises.
