World’s Largest Solar Plant Could Power 230,000 Homes
Located on 2,400 acres of land between Yuma and Phoenix, AZ, Agua Caliente is now operational as the world's largest PV solar facility in the world. The 290-megawatt (MW) project uses solar energy to avoid the annual emission of about 324,000 tons of carbon dioxide into the atmosphere—equivalent to taking nearly 70,000 cars off the road.
Under a 25-year power purchase agreement, NRG and MidAmerican sell solar power to Pacific Gas & Electric Co. At peak capacity, the plant will generate enough energy to power 230,000 homes.
NRG was also involved in another record-setting solar project this year—the launch of Ivanpah, the world’s largest concentrating solar thermal power plant.
“Proving that we can build both the world’s largest solar thermal and now one of the world’s largest solar photovoltaic facilities advance NRG’s mission to reshape the energy landscape that is incredibly beneficial to both the economy and in how we produce and consume energy," Tom Doyle, president of NRG Solar, said in a statement.
FirstSolar designed and constructed the project using advanced thin-film PV modules and will operate and maintain the facility for NRG and MidAmerican Solar. Peter W. Davidson, executive director of the Loan Programs Office (LPO) said the energy companies received a $967 million loan guarantee for Agua Caliente. In a blog post for the U.S. Department of Energy, Davidson displayed pride in aiding clean energy.
"Despite the strong and consistent public demand for greater development of solar energy, these achievements seemed more aspirational than attainable in 2009, given the state of financial markets at the time," Davidson wrote. "However, with the help of loan guarantees, these projects were able to move forward.
"We aren’t done yet. By the end of next year, we expect all five solar PV plants in our portfolio to be completed with a combined capacity of 1,510 MW—enough to power more than a quarter million average American homes."
Agua Caliente is the largest of 10 operational utility-scale solar PV facilities in three states that NRG has an ownership interest in. By this time next year, it may no longer be the largest PV plant, as work continues on another MidAmerican project, the 550 MW Topaz Solar Farm in San Luis Obispo County, CA.
“In 2012, our company made a commitment to invest in its first utility-scale solar project to foster economic development while demonstrating our commitment to the environment,” said Richard Weech, chief financial officer of MidAmerican Renewables.
“It is exciting to see this project become fully operational and begin to realize the full benefit of emissions savings with the clean energy generated at Agua Caliente.”

Hurricane Florence, which battered the U.S. East Coast last September, left a trail of ruin and destruction estimated to cost between $17 billion and $22 billion. Some of the damage was all too visible—smashed homes and livelihoods. But other damage was less so, like the long-term environmental impacts in North Carolina from hog waste that spilled out over large open-air lagoons saturated in the rains.
Hog waste can contain potentially dangerous pathogens, pharmaceuticals and chemicals. According to the state's Department of Environmental Quality, as of early October nearly 100 such lagoons were damaged, breached or were very close to being so, the effluent from which can seep into waterways and drinking water supplies.

Plastics have been recorded in every corner of the world, from the remote icy waters of Antarctica to the bellies of deep-sea fishes. Now, preliminary findings presented at this year's American Association for the Advancement of Science (AAAS) annual meeting in Washington, DC suggest that bird eggs from the high Arctic—one of the most remote wildernesses on the planet—show evidence of contamination from chemicals used in plastics.
A small Australian rat that lived on a 12 acre island in the Great Barrier Reef has become the first mammal to go extinct primarily because of human-caused climate change, the Australian Government confirmed Monday.
The Bramble Cay melomys was first declared extinct after a 2014 search on Bramble Cay, its native island in the Torres Strait, between Queensland, Australia and Papua New Guinea, according to a 2016 report by the University of Queensland and the Queensland government.
