Regulators should stop playing the greed card

In early February, Western GeoPower (WGP) announced its termination of a 20-year geothermal power purchase agreement (PPA) with Pacific Gas and Electric Co. (PG&E). A WGP press release explains that the company terminated the agreement because a regulatory approval condition had not been obtained within a 180-day time period stipulated in the PPA. WGP’s CEO, […]

Raft River Geothermal Project, Malta, Idaho

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.

Investment in generation is heavy, but important needs remain

Forecasting the direction of the U.S. electric power industry for 2007, much less the distant future, is like defining a velocity vector; doing so requires a direction and speed to delineate progress. In this special report, POWER’s first stab at prognostication, the editors look at current industry indicators and draw conclusions based on their more than 100 years of experience. To borrow verbatim the title of basketball legend Charles Barkley’s book: I May Be Wrong but I Doubt It.

Turning the corner on global warming

In his keynote speech this May to the Global Roundtable on Climate Change, held in Iceland and hosted by the Earth Institute of Columbia University, Ólafur Ragnar Grimsson—the president of Iceland—challenged government and business leaders to take measurable steps now to build a prosperous and sustainable future through smart science and public policy. Grimsson’s call […]

Renewable contracts merit longer terms

The length of term allowed for power sales contracts is a critical determinant of the ability of states to meet their increasingly ambitious renewable power targets. Many utilities advocate limiting terms to 10 or perhaps 15 years for renewable energy contracts, emphasizing the "flexibility" that shorter terms offer. In contrast, contract terms of 20 or […]

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.
