Cogen Project Summary

Nippon Paper Industries USA operates a lightweight paper mill at Port Angeles, WA. The mill has been in continuous operation more than 95 years.

NPI USA recently built a new Biomass boiler with attached Co-Gen facility. With start-up of the new boiler facility the mill produces more than 20 Megawatts of certified renewable sourced electricity per hour and provides all required steam to the paper mill.

This new facility allows NPI USA to retire our existing inefficient biomass boiler. NPI USA to sells 100% of our electrical output into the Western Region renewable energy market.

Date of Commercial Operation

The Boiler attained full operational status in early 2015.


The project was 100% financed through its parent company, Nippon Paper Group. Our project is not contingent on any other sources of money or successfully obtaining and signing a long term Power Purchase Agreement.


NPI USA owns two existing dedicated transmission lines from the mill site to the BPA 230KV Port Angeles substation. An Interconnection System Impact Study was completed by Bonneville Power Administration (BPA), which showed no additional facilities are needed to interconnect the project.

Fuel Supply

The NPI USA mill currently purchases the required 150,000 bone dry tons (BDT) of biomass annually from locally available residual forest waste slash and lumber mills.


All electricity produced will meet applicable requirements for WA I-937 or Federal Guidelines. All electricity to be sold with the Green Tags attached. Our electricity is certified as RPS Catagory 1 by the State of California.
