POWER congratulates DONG Energy and Siemens Power Generation on the October 18 inauguration of their 90-MW Burbo Bank Offshore Wind Farm. This project was the first commercial application of Siemens’ new 3.6-MW wind turbine and exemplifies how the right developer and supplier team can quickly add much-needed offshore wind power to a country’s generation mix.

Central Vermont Public Service developed the nation’s first farm-to-consumer renewable energy choice by using cow manure to generate electricity. CVPS gave beleaguered farms new economic hope; developed a generation system that provides clean, renewable energy; and helped solve numerous manure management environmental challenges. CVPS and Cow Power’s four member dairies are recognized as a 2007 Top Plant for generating renewable energy one cow at a time.

Concentrating solar thermal projects fell out of favor more than 15 years ago, when the last SEGS plant was commissioned. But advances in reflective mirror, thermal receiver, and tracking system technologies have significantly improved the systems’ energy conversion efficiency at a much lower capital cost. POWER recognizes Nevada Solar One as a 2007 Top Plant for pushing the limits of solar thermal technology and for being the first of a new generation of concentrating solar projects now being developed around the world.

Geothermal power is a unique renewable energy because it has the best potential capacity factor and is perhaps the only option for baseload power generation. U.S. Geothermal has constructed the first geothermal plant in Idaho in a generation by restoring an abandoned DOE demonstration project site that may possess a development potential of over 100 MW using proven power generation technology. The success of Raft River may well determine the future of geothermal energy production in Idaho.

This year, for the first time, the U.S. wind power industry is poised to push past the 3,000 MW installed per year milestone. At 20 MW, Steel Winds may seem like a footnote, but its importance is measured in more meaningful terms than just size. Steel Winds is the first commercial deployment of the Clipper Windpower 2.5-MW Liberty turbine, the first installation on a former Superfund site, and is said to be the largest wind farm in the U.S. developed in an urban setting. In addition, the project anchors Lackawanna’s redevelopment of a former industrial site along Lake Erie for public use.

Acquiring capacity from renewable resources is now mandatory for many electric utilities, and nowhere is green generation being pursued with more vigor than in California. Regulators there want power from renewables to account for at least 20% of utilities’ annual sales by 2010, and Governor Schwarzenegger is proposing increasing the minimum to 33% by 2020. Wind power appears to have the lowest technical risks of the renewables options, but don’t ignore the rising development risks. Here’s a primer on developing wind projects in the Golden State—and elsewhere.

Stator cooling water treatment is often ignored—until the generator fails. Proper treatment and monitoring is essential to keeping the copper in your stators, where it belongs.

During this 125th anniversary year, Retrospective has surveyed the evolution of the power industry as chronicled in POWER. The magazine’s original focus in the 1880s was to fill the fledgling industry’s technical information vacuum and share common operating experiences. Our goals today are remarkably similar, as technology continues to change and operators continue to learn […]

The eyes of Texas—and the rest of the world—are upon NRG Energy after its September application for licenses for two new reactors at South Texas Project (see Global Monitor). The filing was the first of its kind in nearly three decades and the first of up to 30 like it expected over the next few […]
