Welcome to the informational page on the Plumas Health and Human Services Center Biomass Project! We will use this page to share project details with the public. We will work to post regular updates throughout construction. Please contact project manager Camille Swezy at email@example.com with any questions.
The Sierra Institute was awarded a $2.6 million EPIC grant from the California Energy Commission (CEC) in 2015 for design and construction of a biomass-fired heating system at Plumas County’s Health and Human Services Center (HHSC). This facility will provide heat to the HHSC, and will generate electricity through an Organic Rankine Cycle process to supplement the power needs of HHSC during the winter months. Wood chips derived from sustainable forest management activities within Plumas County will fuel the boiler, and the entire system will be housed within California’s first full cross laminated timber (CLT) building.
Once fully constructed and operational, Plumas County will serve as the prototype for how rural, forested communities can advance utilization of locally-sourced biomass material to benefit both localeconomies and surrounding forestland.

Construction launched early August 2017 and will continue through January 2018. A rough development timeline is as follows:
- Excavation and compaction: August to early September 2017
- Foundation/pour concrete slab, trenching to main building: September through early October 2017
- CLT building construction: November 2017 (delayed from October)
- Equipment installation, commissioning: December 2017 – January 2018
Week of 10/23: Main slab concrete pour
Week of 10/16: Main slab steel:
Week of 10/2: First pour, placement of pre-cast vault (for ash pit)
Week of 9/25: formwork and steel
Week of 9/11: excavation and ground stabilization work has completed, and crews are moving on to the foundation prep phase. Utility lines, below grade bins, and footings are being placed this week and next. The concrete slab will be poured toward the end of the month.
Week of 9/5 : crews have spent the past several weeks performing the excavation and ground strengthening work at the project site. Geogrid material and base rock have been added in layers to ensure the ground will support the heavy timber and biomass equipment. We anticipate the foundation development work to begin the week of September 11.
