Peru commissions hydro plant

The 130-MW Yuncán  hydroelectric plant (Figure 4) has come online in Peru about 210 miles northeast of Lima. To show his support for the project, Peruvian President Alejandro Toledo Manrique attended the inauguration ceremony. Yuncán  was commissioned just 21 months after the Peruvian government awarded a 30-year contract to operate the plant to EnerSur, the […]

Atlantic City bets on renewables

New Jersey’s gaming mecca is hosting one of the largest hybrid (solar-wind) power plants in the world (Figure 3). The Jersey-Atlantic Wind Farm, with 7.5 MW of wind capacity and 0.5 MW from photovoltaic (PV) cells, is expected to generate 20,000 MWh annually. That should be enough to power an adjacent wastewater treatment plant operated […]

Tapping the western sun

In an effort to tap the significant solar energy resources of New Mexico, Arizona, Nevada, California, Utah, Texas, and Colorado, the U.S. DOE will support efforts to install a total of 1,000 MW of concentrating solar power (CSP) systems over the next five years. "This initiative will provide a substantial engine for economic development, job […]

Gas-fired tomatoes

Abating the emissions of power plants is a very hot topic these days. So it’s not surprising that people are coming up with innovative ways to not only cut emissions but also make money from them. The latest brainstorm comes from—where else—the Massachusetts Institute of Technology, where Moshe Alamaro, an atmospheric scientist, has come up […]

Renewable energy’s growing share

  Renewable power development will continue to grow in the U.S., with the nonhydro total reaching 53,121 MW by the end of 2016. So predicts a soon-to-be-released report from Boulder, Colo.–based Platts Analytics (which, like POWER, is a part of Platts, a division of The McGraw-Hill Companies). If all that capacity goes on-line, it would […]

Sun drives pistons and generator, GM

  Sun drives pistons and generator Sandia National Laboratories is joining forces with Stirling Energy Systems Inc. (SES) of Phoenix to test and develop new solar dish-engine systems. Five new systems installed at Sandia’s National Solar Thermal Test Facility in New Mexico joined a prototype Stirling system that was erected earlier in 2004. The six-dish […]

A new player in backup power

For thousands of U.S. businesses, a lesson learned the hard way over the past few years is the need for an absolutely reliable electricity source. Challenging the standard backup power options, proton exchange membrane fuel cells are making a play for this duty.

Roadmap for the all-electric warship

One of the key projects at the U.S. Navy’s Office of Naval Research is developing an integrated ship power system capable of supplying power both to propulsion systems and to advanced electric weapons, launchers, and high-power sensors. It would be the ultimate naval power T&D system. The "all-electric warship," which some predict will have as much of an impact on navies as the nuclear submarine, is still a decade or two away. But the first generation of electric systems is already being installed on U.S. warships currently under construction.

Bonus to Siemens

Siemens Power Generation (Erlangen, Germany) announced late last year that it had acquired wind turbine manufacturer Bonus Energy A/S (Brande, Denmark). With a market share of about 9%, Bonus was one of the top five manufacturers of wind turbines in 2004. On paper, Siemens now seems well-positioned to challenge the market leaders (GE Wind, Vestas, […]

Geothermal: Hotter than ever  

Balmy days are on the horizon for geothermal energy. The renewal of the Production Tax Credit in the U.S. and improved drilling and electricity production techniques are the two main reasons geothermal energy advocates are bullish about the industry. POWER looks at some interesting installations and explains why the optimism is well-founded.
