Top Plants: La Collada Wind Farm, Tarragona Province, Spain

Ironically, the Spanish province of Tarragona — well known for its many Roman and Medieval ruins, archeological digs, and multiple World Heritage Sites — now has one of the most cutting-edge wind farms in the world. This wind farm recently added an innovative 3-MW wind turbine, which stands 140 meters (459 feet) high and is the largest nationally manufactured wind turbine installed in Spain to date.


Top Plants: Thermo Plant, Beaver County, Utah

Geothermal energy projects are gaining steam in many parts of the western U.S., in large part because geothermal power has the advantage of being a renewable energy source that provides baseload power with no emissions and no waste by-products. One example of the latest developments in geothermal power generation is the recently completed 10-MW geothermal plant in rural Utah, which uses innovative modular power generation units.


Top Plants: Covanta Onondaga Waste-to-Energy Plant, Jamesville, New York

Covanta Energy Corp. doesn’t believe in wasting waste. Since 1995 the Covanta Onondaga waste-to-energy (WTE) plant has converted approximately 4 million tons of solid waste into 3 million MWh of clean electricity. Additionally, unlike power plants that use wind or solar energy, this 39-MW WTE facility operates 24/7, making it and similar WTE plants among the most continuously reliable sources of renewable electricity generation currently in operation.

UK takes offshore wind capacity crown from Denmark

Opening of the 194-MW Lynn and Inner Dowsing wind farms built by UK energy company Centrica off the coast of Skegness, in Lincolnshire, this October made the UK the worldwide king of installed offshore wind capacity. The farms raise the total electricity generated from offshore wind in the UK to 590 MW, beating Denmark’s 423 […]

California’s GHG plan gives power heaviest load

On Sept. 12, the California Public Utilities Commission (CPUC) and California Energy Commission (CEC) took the next step in the implementation of Assembly Bill (AB) 32, California’s ambitious greenhouse gas (GHG) emissions – reduction initiative, with the release of a 300-page proposed decision on GHG regulatory strategies.


Advanced tidal stream project planned for UK coast

Scotland is strategically placed at the widening funnel in which the churning waters of the North Sea meet those of the Norwegian Sea. The region is thought to have 25% of Europe’s tidal power resources and 10% of its wave power potential. Recently, the Crown Estate, which owns the UK seabed and controls the rights […]


Under construction in South Africa

This summary of power generation projects is a web-only supplement to the November 2008 special report titled “Whistling in the dark: Inside South Africa’s power crisis.”


U.S. sees 20% jump in planned geothermal

The U.S., which continues to lead the world in on-line geothermal energy capacity, saw a 20% jump in new power projects since January this year, a survey released by the Geothermal Energy Association (GEA) in August showed.


New workshop completes first overhaul

In early August, a special transport departed from Voith Siemens Hydro’s Heidenheim workshop bearing the company’s 300-ton, 300-MVA hydro motor-generator back to Schluchseewerk AG’s Wehr pumped-storage station in Germany’s Black Forest.
