The Sierra Club, Defenders of Wildlife, Santa Clara Valley Audubon Society, the California Department of Fish and Wildlife (CDFW), and Panoche Valley Solar LLC (a subsidiary of Consolidated Edison Development Inc.) have entered into a settlement agreement concerning the size and location of a solar project currently under development in California’s Panoche Valley. According to the environmental groups, the agreement will help advance renewable energy in the state, create local jobs, and protect the environment. Once final, the settlement will permanently conserve more than 26,000 acres for wildlife habitat.

Initially, 247 MW of solar generation was planned for development in the Panoche Valley, but now approximately 100 MW is instead proposed for development at a site in Imperial County, Calif. Development at the Imperial County site will have less impact on threatened and endangered species and their habitat. The relocation of that portion of the project is subject to approval by Southern California Edison (SCE) and the California Public Utilities Commission (CPUC). The settlement will also resolve several legal challenges commenced against the project by the environmental groups.

The groups say the Panoche Valley Solar Project was first proposed in 2009 and, as planned, would have directly impacted nearly 5,000 acres of high-quality and uniquely important habitat. This settlement will reduce the size of the project in the Panoche Valley to slightly more than 1,300 acres and permanently conserve approximately 26,418 acres in and around the Panoche Valley.

The environmental groups assert that the Panoche Valley has the last intact, but unprotected, grasslands in the San Joaquin Valley and is home to many rare and endangered species, including the giant kangaroo rat, the San Joaquin kit fox, and the blunt-nosed leopard lizard. The valley is also designated an Important Bird Area of Global Significance by the National Audubon Society and Birdlife International because the grasslands provide essential habitat for myriad resident and migratory bird species. All of these species have been under threat from the expansion of housing developments, agriculture, oil and gas exploration, and drought, according to the groups.

Sarah Friedman, Sierra Club’s senior campaign representative for the Beyond Coal Campaign, says, “As we work toward lowering carbon pollution, it’s critical that new clean energy development is not done at the expense of endangered animals and their habitat. The Panoche Valley is critical habitat for three highly endangered species, and the development throughout the valley as originally planned would have been devastating. This settlement agreement came about after years of work to preserve the endangered wildlife and delicate habitat in this valley.”

Kim Delfino, Defenders of Wildlife’s California Program Director, says, “When projects are planned ‘smart from the start,’ it ensures that we will not sacrifice California’s natural heritage to meet our clean energy goals.”
