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.

Turkey Opens Record-Breaking Combustion Gas Engine Plant
Turkey, a country that has seen rapid economic growth since the 1980s, largely spurred by a shift in governmental strategy to open up markets and increase private participation, has been actively overhauling its power infrastructure to meet soaring electricity consumption. According to grid operator Turkish Electricity Transmission Co., national consumption increased to 17 billion kWh this September—an 11% increase over the 15.3 billion kWh consumed in September 2009.

MIT Researchers Invent Self-Renewing PV Technology
Scientists at the Massachusetts Institute of Technology (MIT) have a created a set of self-assembling molecules that can turn sunlight into power, and which can repeatedly be broken down and reassembled by adding or removing solution. The scientific breakthrough—inspired by a natural process used by plants to renew light-capturing molecules that have been degraded by the sun—could mean that researchers are closer to creating a self-healing photovoltaic (PV) technology that can keep repairing itself to avoid loss in performance.

UK Cancels Tidal Barrage Plans, Approves Key Nuclear Sites
The UK government in late October shelved plans to build the Severn barrage—a project that would have involved building a 10-mile dam across the mouth of the Severn River—after a two-year-long feasibility study failed to convince ministers to use public funds to build it. The Department of Energy and Climate Change instead gave its long-awaited approval to eight sites for new nuclear reactors, saying that private companies could begin building the country’s new fleet of reactors, provided no public subsidy is involved.

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.
