Oregon Coal Fired Plant Goes Biomass

Aging, inefficient and expensive to upgrade, the Boardman Plant could have joined dozens of similar coal-fired generating stations consigned to the scrap heap of history as its owner prepared to permanently mothball its 600 megawatts in 2020.

Instead, Portland General Electric is in the middle of a grand experiment to see if the plant in eastern Oregon can be successfully converted into the world’s largest biomass power plant.

The plant dates from the 1970s and the utility already filed plans with state regulators to permanently shut it down because of the cost associated with bringing it into compliance with early 21st-century environmental mandates currently on the books and with any future carbon regulations.

“The mandate allows a small opening for repowering, so we looked at biomass and natural gas, but its large Rankine cycle boiler is very inefficient for gas,” Jaisen Mody, PGE’s general manager of generation projects, said. “We started looking at biomass and looked at a technology called torrefaction, and the more we looked at it, the more it intrigued us.”

But biomass power plants may fail because they don’t receive a consistent supply of fuel, which makes securing a long-term power purchase agreement difficult. There are other obstacles, mainly due to the plant’s size.
