What is Biomass?

Images of various sources of biomass materials

Biomass is renewable, organic material that can be used as a fuel or energy source. Some examples include all types of plant materials (forest thinnings, agricultural crops and residue, wood and wood waste), animal waste, landfill methane gas, sewage and solid waste.

Renewable Energy in CT

Connecticut statutes define "renewable sources of energy" as energy from direct solar radiation, wind, water, geothermal sources, wood and other forms of biomass.

Connecticut has a Renewable Portfolio Standard that requires electricity providers obtain a minimum percentage of their retail load from renewable energy. The RPS outlines the three classes of renewable energy. For 2007, the RPS is 7.5% increasing to 14% by 2010, 19.5% by 2015 and 27% by 2020.

What is "sustainable biomass"?

The term sustainable biomass has been defined in the Connecticut General Statutes Section16-1(a)(45) as biomass that is cultivated and harvested in a sustainable manner. Sustainable biomass can most likely be certified as a Class I renewable energy source and generally does not mean construction and demolition waste, as defined in CGS section 22a-208x, finished biomass products from sawmills, paper mills or stud mills, organic refuse fuel derived separately from municipal solid waste, or biomass from old growth timber stands. However, there are some exceptions. Please see the full definition.

CT Agencies Involved in Biomass

In Connecticut, agencies that in some way manage or oversee energy issues typically have some involvement in biomass.

  • Connecticut Department of Energy and Environmental Protection (DEEP)
    The DEEP reviews and issues permits necessary for constructing and operating biomass facilities, and has a role in planning and policy regarding the management of the state’s forests, reducing greenhouse gas emissions, and energy.
  • The CT Green Bank (formerly the Clean Energy Finance and Investment Authority Connecticut and the CT Clean Energy Fund) promotes and invests in clean energy sources for the benefit of Connecticut ratepayers.The Connecticut Public Utilities Regulatory Authority (PURA) regulates utility companies in Connecticut and oversees the Renewable Portfolio Standards.
