Rothschild Biomass Cogeneration Plant

We Energies has installed a 50MW biomass cogeneration plant at Domtar Paper Company’s Rothschild mill. The biomass fuel would consist of clean, untreated wood waste such as logging residue, bark and shavings from paper and saw mills and municipal yard waste and right-of-way clearings.

Gundersen Lutheran Biomass Boiler: A Key Part of Gundersen Energy Independence Goal

The biomass boiler represents 38% of Gundersen’s energy independence goal. The boilers create steam that is used to heat buildings in the winter and is used in the laundry and kitchen, as well as to dehumidify the air and sanitize medical equipment.

Mount Wachusett Community College Biomass Project

The college broke ground in April 2002 for the construction of a new wood biomass heating system that came on line for the 2002-03 heating season, replacing the current all electric system.

Community Wood Energy Case Study: Jericho, Vermont

A look at woodchip harvesting, delivery, and usage in a wood energy system at Mt. Mansfield Union High School in Jericho, Vermont to determine the opportunities and constraints around applying the Community Wood Energy model of sustainable production, efficient use, local sourcing, and fair access (SELF) to a typical wood energy system.

Biomass Energy Resource Center Case Studies

BERC drew on existing expertise, recent experience, thorough research, and active communications with its broader established networks to identify and review “best-in-class” applications (with accompanying case studies) in the United States, Canada, Europe, and Scandinavia. Case Studies are broken down into 9 categories.

Case Studies – NYSERDA

Hidley Farm Case Study: This installation of the Econoburn two-stage gasification boiler, integrated with thermal storage and a solar-thermal system at Hidley Farm, is an example of maximizing the efficiency of two complementary renewable heating systems.

North Country School Case Study:  The new 1.4MMBtuh wood chip boiler system is located in a utility building at the core of the campus. Piping leads to the 32,000 square foot main school building, which was previously heated with oil and propane. The wood chip boiler heats the main school building, and is expected to be expanded in the future to encompass an additional four buildings.

The Wild Center Case Study: Advanced Climate Technologies LLC (ACT) in Schenectady manufactured and installed the wood-pellet boiler with 500 kW (1.7MMBtu/hr) capacity paired with solar thermal and thermal storage.
