What some have billed as the world’s largest solar project in the Mojave came under fire again today. This time a baby desert tortoise led the charge with a cohort of environmentalists. While the tortoise provided a slow-motion picket around downtown Oakland, protestors lined up in front of BrightSource Energy’s corporate headquarters, determined to preserve the Mojave desert and keep solar projects local.

At risk of habitat loss from the project, the tortoise is becoming the iconic image for preservation of the Mojave. The Bureau of Land Management put the brakes on two-thirds of the Ivanpah solar farm when field biologists found more tortoises than initially expected. Tortoises found on site are being relocated and fenced off, preventing their gradual return.

Karen Rusiniack, member of the Oakland non-profit preservation group Desert Survivors, claims that relocation of the animals presents risks of its own. “Think about it,” she said. “These are creatures that have very limited resources in the desert. They are set up in their little burrows, they know where their little supermarket is, where they can go and get plants, they make little depressions in the landscape to get their water. They’re at home in their land.”

Two segments of the Ivanpah solar farm are on hold until the federal Fish and Wildlife Service issues a plan for relocating the tortoises. Despite the controversy, BrightSource maintains that the project will finish on schedule in 2013.

Google announced it would invest $168 million in the project. The Department of Energy announced $1.6 billion loan guarantee. And on Friday, the company announced it plans to go public with a $250 million initial public offering. But a recurring issue has popped up: the desert tortoise.

“It’s an endangered species. No project that is sited out there in within their habitat can negatively impact the population,” says Erin Curtis, a spokesperson for the Bureau of Land Management. As anyone following the battles over solar farms knows, prime desert tortoise habitat also happens to be prime solar territory and has been targeted by a number of proposed solar farms.

BrightSource Energy agreed to mitigate the impacts their solar farm would have on the tortoises by capturing and relocating them to new habitat. Fences are being constructed to prevent the tortoises from returning.

In all, biologists are allowed to relocate or handle 38 tortoises over the lifetime of the project. But they’ve been finding more tortoises than expected and have already hit that limit.

“Therefore we needed to suspend activities so we didn’t touch another tortoise until we have a new biological opinion. You’re trying to manage wild animals and they don’t act in a predictable fashion. It’s adaptive management and we learn new things all the time,” says Curtis.

BLM has shut down construction on two sections of the solar thermal farm, until the Fish and Wildlife Service can issue a new decision on how many tortoises are in the area and where they could be relocated to. Biologists are now estimating that roughly 140 tortoises could live in the 3,500 acre project footprint.

That decision is expected to take three to four months and surveys are currently underway. BrightSource Energy has said they don’t expect the solar farm to be delayed.

The federal Bureau of Land Management today issued its first approvals of major solar energy projects in California.

Tessera Energy’s 700-megawatt Ocotillo project, located in the Imperial Valley, about 100 miles east of San Diego, and a smaller photovoltaic (PV) project by San Ramon-based Chevron Corp., are both cleared to go forward.

The two projects set a precedent not just for California. On a call with reporters this morning, Department of Interior Secretary Ken Salazar called it a “historic day,” saying the two projects “bear the distinction of being the first large-scale solar energy projects ever approved for construction on our nation’s public lands.”

For projects being developed on federal land, BLM approval is the final hurdle before construction can begin. Big solar-thermal projects, which concentrate the Sun’s energy to make steam, also require approval from the California Energy Commission (photovoltaic projects, like the Chevron array, are under the eyes of the state’s Pubic Utilities Commission and county governments). State energy commissioners have approved seven major solar installations in the California desert since July. Several of these are still pending BLM approval.

BLM director Robert Abbey uses the catch phrase “smart from the start” to describe his agency’s new approach to site permitting, which he calls “streamlined without cutting corners.” Abbey says the Bureau is still sifting through a backlog of 180 pending applications, nationwide.  He said his agency manages about 23 million acres “with solar potential,” across several western states, about half of that in California.

The Tessera project, shown in some CEC filings as SES Solar Two, could deliver more than 700 megawatts of solar-thermal power when completed late next year. It will occupy more than 6,000 acres of BLM land, and a few hundred acres of adjacent private land. Chevron’s Lucerne Valley project is significantly smaller, rated at 45 megawatts, with a footprint of about 400 acres in the Lucerne Valley of San Bernardino County.

Asked about opposition from environmentalists, Salazar said the projects had won support from several major organizations, including Defenders of Wildlife, the Sierra Club, The Wilderness Society and Natural Resources Defense Council (NRDC).

In a press release, NRDC attorney Johanna Wald wrote that: “the process provided valuable lessons that careful planning, siting and designing up front will lead to renewable projects that are smart from the start.”

Salazar told reporters that transmission lines are already available for all of the Chevron project’s output and a little less than half the expected output from Ocotillo, and that he looks forward to seeing “thousands of megawatts of renewable energy sprouting” over the next few years.

The four California locations (.pdf link) combine more than 350,000 acres in San Bernardino, Riverside and Imperial Counties. They supposedly represent the best combination of production potential, least conflict with other land uses and environmental concerns, and proximity to existing transmission lines or power plants. Areas were also mapped in neighboring Nevada and Arizona.

Update: Scott Streater has more on the controversy over planned renewable power sites, including California’s Iron Mountain site (see map, below),  in a New York Times Greenwire post.

The maps appeared just as California’s main regulator of power companies issued an update on solar projects in the state. The California Public Utilities Commission reported that the rate of new solar installations nearly doubled last year, from 2007 levels.

The CPUC tally shows California with over 500 MW of solar photovoltaic (PV) connected to the electric grid at almost 50,000 customer sites. The report notes that all those electrons combined are equivalent to one large power plant. About half of the current total went in under the California Solar Initiative, which has reached 13% of it’s 10-year goal, with another 8% in pending applications.

Also this week, more than $300 million fell from the federal money tree for a hydrogen power project in southern California. Cash from the American Recovery and Reinvestment Act (better known as the federal stimulus plan) will flow to the Hydrogen Energy California (HECA) project in Bakersfield. The project is designed to provide power for 150,000 homes in the area, by converting oil to hydrogen.

A statement from the California Recovery Task Force (CRTF), a conduit for federal stimulus funds, describes the HECA project as “an Integrated Gasification Combined Cycle power plant that will take petroleum coke, biomas, coal or blends of each, combined with non-potable water to convert them into hydrogen and carbon dioxide (CO₂). The hydrogen gas will be used to fuel a net 250-megawatt power station.”

Perhaps more significant are the plans for the carbon dioxide generated in burning the oil. The CRTF statement says that “The CO₂ will be transported by pipeline to nearby oil reservoirs and injected for permanent storage which will enhance U.S. energy security and enable additional production from existing California oilfields.”

CRTF says the project will “avoid” emissions of more than two million tons of greenhouse gases per year.
