Top Plant: Kaukaan Voima Oy Biomass-Fired Power Plant, Lappeenranta, Finland
Located in the heavily forested country of Finland, the Kaukaan Voima biomass-fueled power plant produces process steam and electricity for UPM’s Kaukas pulp and paper mill as well as electricity and district heating for Lappeenrannan Energia, a city-owned power company. Launched in 2009, the plant can provide 125 MW of electricity, 110 MWth of district heat, and 150 MWth of process steam thanks to one of the world’s largest wood-fired fluidized bed boilers.

New Design Tool Improves Manufacture of Composite Wind Turbine Blades
Composite materials are ideal for producing wind turbine blades because of their strength, light weight, and ability to be tailored to provide the precise mechanical properties needed for any blade design. Now, best practices originally developed for rotorcraft blade manufacturing can be applied to designing and manufacturing wind turbine blades that are constructed from composites.

A Winning Combination: Government and Utilities Partner on Renewable Energy Projects
Recent mandates require government facilities to develop energy policies that enable energy conservation, increase the use of renewable energy, and improve energy security. Utilities with government facilities in their service territory may have opportunities to develop solar and other renewable energy projects that help them meet state renewable portfolio standards while increasing a government facility’s usage of renewable energy. The key to such a win-win proposition is careful structuring of the project agreement to leverage each party’s assets.
