The solution they came to this week provides a model for how to get around the difficulties encountered by utility scale solar companies in getting past NIMBY opposition and other roadblocks to developing big solar in the desert.

The creation of the EcoGrove I Wind Farm was precipitated by the State of Illinois adopting a Renewable Energy Standard that required the state to generate at least 25 percent of its power from renewable energy sources by 2025. Cleaner air, using an abundant and renewable energy source, and providing various community benefits make wind farm development likely to continue, at least until more Americans change our energy-intensive ways.  From my perspective, however, energy independence is more about breaking free from our fossil fuel addictions to coal, natural gas and oil rather than simply securing domestic sources of energy that are polluting and/or add more carbon dioxide into the atmosphere.

The $200 million EcoGrove I Wind Farm is owned and operated by the sustainability-focused business Acciona Energy North America; its parent company is Acciona S.A., headquartered in Spain. EcoEnergy LLC and The Morse Group managed various aspects of the planning, mapping, permitting, engineering and interconnections for the project.

The EcoGrove 1 Project comprises 67 turbines spread across about eight thousand acres to create a 100 megawatt (MW) wind farm capable of powering over 25,000 homes. Thirty of the 67 Acciona turbines were manufactured in West Branch, Iowa, with the rest coming from Spain. The energy produced is sold to ComEd (Exelon Corporation) which then directs the energy where needed. An additional two phases are planned.

“The upper Midwest has tremendous wind energy potential and EcoGrove is one great step toward harnessing that potential.” said Kimberly L. Smith, Vice President Construction and O&M Services, Acciona Energy North America.

Below are of the few of the benefits in more detail, though our group was blown away by their sleek design of the blades and the way they towered over the emerging cornfields in early summer.

Las Vegas, Nevada - The current period of sustained growth in the American Southwest is putting tremendous demands on important resources like water, wildlife habitat, and, with the light beaming from the top of Las Vegas’ Luxor Hotel as a reminder, electricity. Nevada currently gets about 90% of its electricity from fossil fuels, and the majority source fuel is natural gas.

As natural gas prices are predicted to rise, a debate is stirring about whether the state needs to build new coal-fire power plants to meet current needs, or whether it should tap its renewable resource potential. For that reason, Acciona Energy could not have picked a better time than today to dedicate their new 64 MW concentrating solar power plant (CSP) in Boulder City, Nevada, less than thirty miles from the Las Vegas strip. And with a star-studded collection of speakers like Ed Begley Jr., NASA astronaut Dr. Sally Ride, and Apple co-founder and tech whiz Steve Wozniak, the Spanish-based Acciona dedicated the facility in true Las Vegas style.

The 300-acre site in Boulder City uses parabolic trough collectors to generate electricity. The 760 mirrored troughs track the movement of the sun’s path, and their 184,000 mirrors face the sky and concentrate the sunlight to a large metal and glass receiver in the middle of the trough that holds circulating oil. The oil travels to heat exchangers, which heat water and create steam that spins a turbine. Seems simple enough, right? Continued…

At 64 megawatts (MW) of generation capacity, Nevada Solar One is the largest CSP plant to be built in 16 years and it makes Nevada the largest per capita producer of solar power in the country. After roughly a decade of little growth for the industry, CSP is coming back strong, as is further evidenced by today’s announcement by Abengoa Solar that they will be building a 280 MW concentrating solar facility in Arizona.

The absence of any new CSP over the last 16 years leaves many people scratching their heads and asking themselves, why? There were some 354 MW of parabolic trough collectors installed in California’s Mojave Desert between 1984 and 1990. And those plants are still in operation, currently producing energy at around $0.12-$0.14/ per kilowatt-hour (kWh). The Nevada Solar One plant will produce electricity at around $0.15-$0.17/kWh.

Just by looking at the National Renewable Energy Labs CSP solar resource map, you might surmise that the US desert southwest has the potential to be the Saudi Arabia of solar resources (although I suppose Saudi Arabia could also be considered the Saudi Arabia of solar resources). However, the federal government must take the lead and adopt policies and incentives that can provide the necessary investment security for companies like Acciona, and Abengoa, to continue their renewable energy development in the American Southwest. And who knows, maybe even an American company or two can get in on a little of this some day. Wouldn’t that be something?
