Amazon agrees to 450 MW solar purchase in California with AES

Amazon.com Inc (NASDAQ:AMZN) has committed to buying electricity from 450 MW of solar parks to power its data centers in California under a deal with power distributor AES Corp (NYSE:AES).

The US e-commerce giant has sealed two power purchase agreements (PPAs) that will see it get renewable energy in the California Independent System Operator (CAISO) market. The power will be sourced from solar photovoltaic (PV) plants and 225 MW of battery storage projects with a four-hour duration.

The off-take deals were announced by AES on Thursday.

Sheep and solar panels: using solar sites for pastureland

,

A solar power boom generated by new renewable energy mandates is unfurling in the Chesapeake Bay region. Virginia, for example, was ninth in the nation for new solar capacity in 2021.

With many solar arrays ending up on farmland, a movement is fast taking hold to make sure that they will benefit the environment, agriculture and wildlife, and not just create a sea of silicon.

Allowing sheep to graze among solar panels has become one attractive antidote.

Microsoft signs 110MW PPA with AES to power California data centers

Microsoft has signed a new Power Purchase Agreement (PPA) with AES to procure renewable energy for its Californian facilities.

AES Corporation this week announced a 20-year agreement with Microsoft to provide renewable energy to its data centers in California.

In what AES called a “highly customized agreement,” Microsoft will partially match its load at their California-based data centers. AES will source the energy from a portfolio of 110MWAC solar and 55MW, 4-hour storage projects in the California Independent System Operator (CAISO) region.

US Senators urge Biden administration to expedite solar tariff investigation decision

Washington–Senator Dianne Feinstein (D-Calif.) joined Senators Jacky Rosen (D-Nev.), Martin Heinrich (D-N.M.), Kyrsten Sinema (D-Ariz.) and a bipartisan group of their colleagues to urge President Joe Biden to expedite and bring to a swift conclusion the administration’s investigation into solar panels and cells imported from Malaysia, Vietnam, Thailanda and Cambodia. This investigation could expand harmful, job-killing tariffs on solar imports, raising costs on consumers, and has already caused widespread cancellations and delays in the U.S. solar industry.

The solar industry employs over 230,000 American workers. According to a new report issued by the Solar Energy Industries Association, 70 percent of U.S. companies say at least half of their solar workforce is at risk as a result of this investigation.

This bipartisan letter was also signed by Senators Thom Tillis (R-N.C.), Tom Carper (D-Del.), Catherine Cortez Masto (D-Nev.), Brian Schatz (D-Hawaii), Sheldon Whitehouse (D-R.I.), Tim Kaine (D-Va.), Michael Bennet (D-Colo.), Mark Warner (D-VA), Chris Coons (D-DE), Jerry Moran (R-KS), Alex Padilla (D-Calif.), Mazie K. Hirono (D-Hawaii), John W. Hickenlooper (D-Colo.), Christopher Murphy (D-Conn.), Chris Van Hollen (D-Md.), Mark Kelly (D-Ariz.), Maggie Hassan (D-N.H.) and Angus King (I-Maine).

Meet the power plant of the future: solar + battery hybrids are poised for explosive growth

America’s electric power system is undergoing radical change as it transitions from fossil fuels to renewable energy. While the first decade of the 2000s saw huge growth in natural gas generation, and the 2010s were the decade of wind and solar, early signs suggest the innovation of the 2020s may be a boom in “hybrid” power plants.

A typical hybrid power plant combines electricity generation with battery storage at the same location. That often means a solar or wind farm paired with large-scale batteries. Working together, solar panels and battery storage can generate renewable power when solar energy is at its peak during the day and then release it as needed after the sun goes down.

Renewable electricity just powered California 100% for the first time in history

Renewable electricity met 100% of California’s demand for the first time on Saturday, environmentalists said, much of it from large amounts of solar power produced along Interstate 10, an hour east of the Coachella Valley.

While partygoers celebrated in the blazing sunshine at the Stagecoach music festival, energy demand statewide hit 18,672 megawatts at 2:45 p.m. local time, and 37,172 megawatts were available to meet it. The power came from renewables, according to a continuous tracker provided by California Independent System Operator, or CAISO,  a nonprofit that oversees the state’s bulk electric power system and transmission lines.

Solar beats nuclear at many potential settlement sites on Mars

The high efficiency, light weight and flexibility of the latest solar cell technology means photovoltaics could provide all the power needed for an extended mission to Mars, or even a permanent settlement there, according to a new analysis by scientists at the University of California, Berkeley.

Most scientists and engineers who’ve thought about the logistics of living on the surface of the Red Planet have assumed that nuclear power is the best alternative, in large part because of its reliability and 24/7 operation. In the past decade, miniaturized Kilopower nuclear fission reactors have advanced to the point where NASA considers them to be a safe, efficient and plentiful source of energy and key to future robotic and human exploration.

Solar power, on the other hand, must be stored for use at night, which on Mars lasts about the same length of time as on Earth. And on Mars, solar panels’ power production can be reduced by the omnipresent red dust that covers everything. NASA’s nearly 15-year-old Opportunity rover, powered by solar panels, stopped working after a massive dust storm on Mars in 2019.

CPUC approves California utility projects including PG&E’s 1.6GW/6.4GWh BESS

The California Public Utilities Commission (CPUC) has approved new projects by the state’s three investor-owned utilities, including nine battery energy storage system (BESS) facilities proposed by PG&E totalling 1.6GW/6.4GWh.

The CPUC has approved the projects which were proposed by PG&E in January in response to an order to procure 11.5GW of clean energy capacity, under the CPUC’s internal resource planning process.

CDCR on track to produce a quarter of its energy needs from renewable sources by 2025

SACRAMENTO– As we celebrate Earth Day, set aside annually to demonstrate support for environmental protection, raise awareness, and work to protect the planet, the California Department of Corrections and Rehabilitation (CDCR) is doing its part.

“Earth Day is marked by more than a billion people around the world. CDCR is working to minimize its impact on the environment with a multi-faceted energy and sustainability program designed to reduce greenhouse gas emissions, conserve water, and reduce its overall carbon footprint,” CDCR Secretary Kathleen Allison said.

Santa Monica solar panel recycling pilot wraps up

Santa Monica solar panel recycling pilot wraps up

On June 27, 2018, the Santa Monica was awarded $50,000 in funding from the Household Hazardous Waste Grant Program of the Department of Resources Recycling and Recovery (CalRecycle). The City worked with the California Product Stewardship Council and other partners to survey stakeholders, conduct outreach, and coordinate panel pickups from homeowners and solar installers.  The CA Conservation Corps picked up and hauled panels and a Universal Waste management company called CalMicro, recycled the panels.

Results
Overall, 281 working and non-working panels were collected from 8 locations for an estimated total recycling weight of 7,920 lbs.  The cost for hauling and recycling solar panels was about $0.62 per pound or $17 per panel.  An additional 78 working panels were diverted for reuse.

Next Steps
Since the pilot is concluded, the City does not have staff or budget to dedicate to processing solar panels at this time, however, there are Universal Waste recyclers in Southern California that are certified to process solar panels and the Habitat for Humanity ReStore in Los Angeles is accepting unwanted working panels.  The California Product Stewardship Council created a website dedicated to the proper handling of unwanted solar panels: calpsc.org/solarpanelstewardship.
