Cogeneration / Wood Pellets

In the forest products industry, Cogeneration typically means that a manufacturing facility (a sawmill for example) burns its waste material, such as bark and sawdust, to produced steam, which is then used to dry lumber and to generate electricity. Since wood wastes are viewed as carbon neutral and renewable, biomass-fired Cogeneration is a small but growing component in the process of supplying “renewable” electricity to meet society’s needs. One factor causing this growth includes the intense focus on “green or renewable” energy production. In fact, due to changes in public policy, “renewable” power projects are being offered a myriad of state and federal financial benefits and tax incentives which can help make the economics of cogeneration more profitable than ever.

Beck has completed several cogeneration studies, including a fuel supply and demand analysis, a feasibility assessment, and representing a client in negotiations with a utility regarding a power purchase agreement. Our past projects on this topic have been located throughout the U.S. and typically involve the analysis of the following factors:

Determine state and federal financial incentive programs
k for a woody biomass electrical generation project

Fiber Supply – regional assessment of available
k residuals from woods to industrial sources, as well as
k the current and future cost of residuals in the market

Size and location of power plant

Estimate the capital cost of converting current
k direct-fired dry kiln(s) to steam (installation and
k equipment cost)

Assess the logistics necessary to maintain kiln
k operation during the transition

Negotiate power purchase agreements with utilities,
k as well as oversee the physical interfacing of the
k power supply to the utility’s grid

Determine permitting, regulatory or environmental
k issues with the site and ensure compliance

Wood pellets are manufactured from woody biomass fuel made from compressed wood waste – usually sawdust or shavings.  The moisture content is around 6-8% and no resin is used as lignin is the binder.  In today’s economy, where oil prices are at historic highs and global energy consumption is at a peak, consumers are looking for renewable energy to heat their homes, and wood pellets have begun to fill that need in earnest.  Currently, demand for wood pellets is far surpassing supply.

Beck has performed several feasibility studies for the production of wood pellets from mill residuals to chipping roundwood.  The analysis covers the following factors:

Raw material supply analysis

Pellet market assessment

Technical assessment of pellet plant, including
k operating cost assumptions and other
k production-related issues

Financial analysis and assessment of economic impact
k of proposed plant
