Largest biomass plant in Calif. scores PPA

By Anna Austin | April 12, 2012

The community-owned power and water utility in Imperial, Calif., has signed a power purchase agreement (PPA) with Greenleaf Power Inc.’s Desert View Power Plant near Mecca, Calif. It's the largest biomass power facility in the state.

The 10-year PPA with Imperial Irrigation District secures 45 MW of electricity, beginning in May, according to IID. At an annual cost of about $35 million, the power will raise IID’s renewable portfolio from 12 to 18 percent. California’s current renewable portfolio standard requires utilities to deliver 20 percent renewable electricity by 2013, with an end goal of 33 percent by 2020.

The 47 MW facility, which employs a circulating fluidized-bed technology, uses urban wood waste, forest and agricultural residue as fuel. It was built in 1992 and was acquired from Colmac Energy by Greenleaf Power in 2010.

Greenleaf is also the owner of the 30 MW Honey Lake biomass plant in Wendel, Calif., as well as a 28 MW biomass plant in Scotia, Calif.
