"The South Treatment Plant’s average daily power consumption is 7.5 MW, but during storms its demand can rise to a peak of 24 MW. Together, the 1 MW fuel cell and the new 8-MW gas-turbine generator will more than cover the plant’s entire electricity base load, though it will continue to rely on PSE for peaking power.” (www.foresterpress.com/de_0511_fuel.html - 41k)

Which, as I said, is an insignificant amount of power. Assuming they are using all the nutrients available, it takes the entire poop output of Renton to generate enough methane to run the poop processing plant. Not terribly practical.

Actually it only requires a small percentage of the city’s daily output. And producing enough electricity for 8,000 home isn’t too bad for a pilot plant using waste.
Sounds way better than algae oil.
