Tacoma Power tidal energy project on hold

Washington state utility Tacoma Power has put its Tacoma Narrows pilot tidal power project on hold after a study found that tidal generation won't pencil out economically for at least 8 to 10 years. The utility on Feb. 28 said it will consider other resources such as wind, geothermal and biomass power to meet renewable energy targets.

Tacoma Power said a follow-up study to an earlier tidal study of the Narrows waterway by the Electric Power Research Institute found that the amount of energy that could be generated was less than EPRI estimated and that tapping the tides requires advancements in turbine technology.

"Tidal power technology is where wind technology was decades ago," said Tacoma Power Superintendent Gary Armfield. "Right now, it wouldn't be a sound nvestment at this site for Tacoma Power and its customers," Armfield said.

"We're not closing the door on this technology," said Tacoma Public Utilities Director Bill Gaines. "But we do recognize that its potential is longer-term. Right now we need to focus on short-term solutions to meet renewable energy requirements," he said in a press release.

Utilities, including PG&E, are eyeing tidal and wave energy to generate electricity and some have pilot programs in early stages.PG&E has entered into a long-term, two megawatt  commercial wave energy power purchasing agreement with Canada's Finavera Renewables Inc. Located off the Northern California coast, the Humboldt County Offshore Wave Energy Power Plant will be developed by Finavera Renewables. The project is expected to begin delivering renewable, clean electricity in 2012.

  • This is being rather generous to Lutz. 1. The "Volt", in no small part, will be targeted as a product to people who care about energy and environmental issues. These people don't embrace Lutz' antideluvian concepts of rejecting science. How responsible is it for a GM executive to be rejecting the science? 2. As well, Lutz didn't exactly sound too enthusiastic about the Volt itself. 3. And, GM public communications has 'defended' Lutz in rather absurd ways. -A Siegel

  • This article is right on - small businesses have a huge role to play in sustainability. Not only do they add up in aggregate, but many small businesses operate in industries that can have a significant environmental impact depending on the exact practices, like dry cleaners, auto repair shops, etc. Green is also starting to affect the bottom line more and more, customers are increasingly voting with their feet for more sustainable businesses as can be seen from the growth of sites like http://www.ecovian.com. This is also a huge opportunity for small businesses to leapfrog their bigger brothers by being more agile in adopting these measures. -Emily

  • Great entry, Katie. Love the level of detail you managed to get in there! Probably won't be able to compete with coal and oil any time the next decade, but definitely a great technology to look into! Keep it up :) -Rune (Norway)
