The Hyland Landfill renewable energy facility is one of four LFG energy projects brought on line in 2008 by Casella Waste Systems, Inc. Casella and its partners now produce roughly 25 MW of clean energy at five of the company's landfills. Casella's dedication to generating green power and reducing greenhouse gas emissions earned it LMOP's 2008 Industry Partner of the Year award.

Casella overcame numerous regulatory and legal challenges to complete the project. For example, due to constraints in the Village of Angelica's power supply agreements, Casella was not able to interconnect to the village's electric system. Instead, they installed a new 6-mile transmission line to transmit the green power through an overbuild circuit to New York State Electrical & Gas Company (NYSEG), which sells the electricity in the New England power market.

The Hyland Landfill project's highlights include the following:

  • Three Caterpillar 3520 engine-generator sets with capacity for a fourth
  • Large portion of Angelica's electrical system was upgraded, including replacement of poles and lines that dated to the 1930s
  • New lines improve reliability of the village's incoming power feed

As a charter member of the EPA Climate Leaders program, Casella has committed to reduce its total GHG emission footprint to 10 percent below 2005 levels by the year 2012. In addition to completing four LFG energy projects in 2008, Casella also initiated development of four additional projects.

We believe that waste is no longer just a throw-away, but is instead a raw material for manufacturing new products and a resource for producing clean energy. Investments in resource transformation solutions, such as landfill gas-to-energy facilities position the company to take advantage of significant economic, environmental policy and cultural shifts by pursuing opportunities that create both economic and environmental value from waste. —John W. Casella, Chairman and Chief Executive Officer, Casella Waste Systems
