WAITSFIELD, Vt.--(BUSINESS WIRE)--Sept. 10, 2002

Pioneering Company to Provide Environmental Vision

for Using Alternative, Renewable Power Sources

Northern Power Systems today announced that it has been commissioned by Yale University, New Haven, Conn., and Middlebury College, Middlebury, Vt., to provide engineering studies to test the integration of renewable power into new buildings currently under design and for a college ski area on their respective campuses. Additionally, Steven Winter Associates, a leading environmental developer, has tapped Northern to assess the feasibility of installing wind power in two public parks contained in the new Queens West Waterfront Development in Long Island City.

Northern will analyze both economic and functional objectives for energy supply at Yale University as the school designs a new building for the School of Forestry and Environmental Studies (F&ES). Integrating renewable power and reviewing opportunities for significant emissions reductions from cogeneration applications in its new facility will support the F&ES goal of creating a climate neutral building and demonstrating sustainability in an urban context.

At Middlebury College, Northern's study will evaluate the potential for on-site wind generation. Under consideration is the installation of Northern's R&D 100 Award-winning NorthWind 100 wind turbine to provide real renewable generation offsets for the main campus. If implemented, the turbine is expected to generate approximately 35% of annual consumption at the college's ski area (The Middlebury "Snow Bowl"), an estimation that Northern's study will confirm. "Early analysis shows that the installation of wind turbines could help us reduce our carbon emissions," said Nan Jenks-Jay, director of Environmental Affairs at Middlebury College. "We are excited to see the results of Northern Power's study upon its completion and look forward to assessing our options. Because this phase of analysis was inspired by work of two Middlebury students this year, who looked at the economic benefits and wind potential at the site, Northern Power's results will be even more meaningful to the College."

Queens West Waterfront is a joint effort of the public and private sectors to create a mixed-use development comprising residential and commercial buildings surrounded by parks and recreational areas. Consisting of approximately 68 acres of prime waterfront land directly across the East River from the United Nations, Queens West is taking a step toward establishing itself as a pioneer in sustainable urban development by commissioning the study.

"By commissioning these energy options studies, Yale, Middlebury and Queens West have demonstrated their commitment to a better environment and a more efficient means of power," said Jito Coleman, President of Northern Power Systems. "Through our feasibility studies, Northern is helping these and other progressive institutions take a first step toward realizing their environmental visions through renewable power."

For each project, Northern will use computer models to map the correlation between generation sources and load demand. These correlations will help to predict the performance of a system over a one-year period. The results will then be compiled and used to conduct a life cycle cost benefit analysis -- taking fluctuating fuel costs, electric rate structures, and maintenance schedules into consideration. Based on all these factors, and time value of money, a final analysis will determine the overall feasibility and worth of the project. Additionally, the study will highlight the amount of emissions avoided as well as other environmental benefits.
