When I was scouting around for co-gen operations in the early '80s, you
needed several things to have a successful co-gen operation. For each Meg
of generation, about 10,000 tons of wood waste is needed. There must be a
use for low pressure trash steam. This can be process steam for food
plants, or heat for large buildings (a hospital was considering it). The
real kicker is that you need a really good electric contract price. We were
using a 6.6 cent/kwh and wood waste at $12/ton to make the project viable.
It ended up being a 25 Meg plant, and I found wood waste available to site
But, times have changed and electric capacity has increased. Electric
companies no longer are looking for any type of suppliers. Our traditional
electric supplier has sold TMI to a foreign company and now is only in
distribution. It may be feasible if you provide electric to an industrial
park, where you can beat industrial prices. The electric company will
undercut you just to take the business away.
