On the afternoon of April 14, 2020, dozens of firefighters arrived at an Amazon warehouse in Fresno, California, as thick plumes of smoke poured from the roof of the 880,000-square-foot warehouse.
Some 220 photo voltaic panels and different gear on the facility, often called FAT1, had been broken by the three-alarm hearth, which was brought on by “an undetermined electrical event within the solar system mounted on top of the roof,” Leland Wilding, Fresno’s hearth investigator, wrote in an incident report.
Just a little over a yr later, about 60 firefighters had been known as to a good bigger Amazon facility in Perryville, Maryland, to place out a two-alarm blaze, native information shops reported.
In the intervening months, at the least 4 different Amazon achievement facilities caught hearth or skilled electrical explosions as a result of failures with their photo voltaic energy-generating programs, based on inside firm paperwork seen by CNBC.
The paperwork, which have by no means been made public, point out that between April 2020 and June 2021, Amazon skilled “critical fire or arc flash events” in at the least six of its 47 North American websites with photo voltaic installations, effecting 12.7% of such services.

“The rate of dangerous incidents is unacceptable, and above industry averages,” an Amazon worker wrote in one of many inside stories.
The photo voltaic snafus underscore the problem Amazon and plenty of different massive companies face of their quest to shrink their environmental footprint and scale back reliance on fossil fuels. Amazon has been among the many most aggressive. In 2019, founder Jeff Bezos launched the Climate Pledge, promising the biggest on-line retailer would zero out emissions by 2040, embrace renewable vitality and transfer away from gas-guzzling supply vans, together with via a billion-dollar-plus funding in electrical automobile firm Rivian.

Corporate America is underneath strain from regulators and a rising subset of buyers to set and report on environmental, social and governance (ESG) targets.
Many will be capable to reap monetary rewards for renewable vitality efforts after Congress in August handed the Inflation Reduction Act, which incorporates local weather provisions projected to cut back the nation’s carbon emissions by roughly 40% by 2030.
Commercial photo voltaic within the U.S. is anticipated to see 8% annual progress over the subsequent 5 years, thanks partially to the laws, based on Wood Mackenzie photo voltaic analyst Michelle Davis. Warehouses can take outsized benefit of photo voltaic, she mentioned, as a result of they’ve massive roofs and the programs can energy all of the HVAC, refrigeration and different energy-heavy programs situated inside.
But expensive and harmful points can come up.

By June of final yr, all of Amazon’s U.S. operations with photo voltaic needed to be taken offline briefly, inside paperwork present. The firm had to make sure its programs had been designed, put in and maintained correctly earlier than “re-energizing” any of them.
Amazon spokesperson Erika Howard advised CNBC in a press release that the incidents concerned programs run by companions, and that the corporate responded by voluntarily turning off its solar-powered roofs.
“Out of an abundance of caution, following a small number of isolated incidents with onsite solar systems owned and operated by third parties, Amazon proactively powered off our onsite solar installations in North America, and took immediate steps to re-inspect each installation by a leading solar technical expert firm,” the assertion mentioned.
Those particulars did not present up in Amazon’s 100-page sustainability report for 2021, which was printed at the start of August. In that report, out there to the general public through Amazon’s sustainability web site, the corporate mentioned rooftop photo voltaic was powering 115 of its achievement facilities throughout the globe by the top of 2021, up from greater than 90 in the midst of the yr. The majority of these are exterior the U.S.
“Many of our fulfillment facilities throughout the U.S., Europe, and India are powered by on-site solar, where a rooftop installation can power up to 80% of the facility’s energy use,” the report mentioned.
By April of this yr, Amazon had onsite photo voltaic at 176 services, based on its web site. The photo voltaic program was launched in 2017.
“As inspections are completed, our onsite solar systems are being powered back on,” Howard mentioned. “Amazon also built a team of dedicated solar experts overseeing the construction, operations, and maintenance of our systems in-house to ensure the safety of our systems.”
Excluded from the general public sustainability report is any point out of the bills Amazon incurs when there is a failure. An Amazon worker estimated, within the paperwork circulated internally, that every incident value the corporate a mean of $2.7 million. Costs included third-party audits of rooftop photo voltaic programs, checks on how a lot electrical energy they had been producing and repairs for any damaged or defective components of the programs that inspectors recognized.
The Amazon worker additionally mentioned the corporate would lose $940,000 monthly, or $20,000 for every of the 47 decommissioned North American websites, so long as the photo voltaic remained offline. There may very well be further prices for Amazon relying on contracts with clear vitality companions for renewable vitality credit, the paperwork present.
To date, Amazon has contracted with third-party distributors to design, then set up photo voltaic photovoltaic programs on rooftops and massive backup batteries on web site. Other main retailers, together with Walmart and Target, have additionally put in photo voltaic rooftops and adopted packages to trim their vitality payments and attain sustainability targets.
In addition to its warehouses, Amazon has some photo voltaic roof programs at its Whole Foods shops. Amazon and its auditor, Clean Energy Associates (CEA), postpone inspection of the photo voltaic rooftop programs at Whole Foods areas till 2022, the paperwork mentioned. As of late 2021, 4 years after buying Whole Foods, Amazon was nonetheless working to realize technical details about the renewable vitality property on the shops.

To preserve tighter high quality management of its photo voltaic vitality programs, some Amazon workers really helpful bringing extra operations in-house. The hearth in Perryville, Maryland, which was the sixth failure in slightly over a yr, spurred the corporate to take systematic motion.
On June 17, 2021, roughly every week after the hearth on the warehouse often called MDT2, Amazon’s sustainability division directed the house owners and builders of photo voltaic rooftop programs on its U.S. warehouses to decommission them. The photo voltaic rooftops would now not be producing electrical energy from the solar or producing renewable vitality credit.
Amazon then employed Denver-based CEA to conduct a third-party audit of its rooftop photo voltaic programs within the U.S., Asia-Pacific and Europe, Middle East and Africa area.
Late final yr, whereas CEA was nonetheless conducting its inspections, it knowledgeable Amazon of 1 crucial and 259 main findings throughout Amazon’s rooftop photo voltaic portfolio. Problems included mismatched module-to-module connectors, improper set up of connectors, poor wire administration and proof of water intrusion within the inverters, inside paperwork mentioned.
Issues with inverters, which convert photo voltaic vitality into usable electrical energy, had been recognized because the possible trigger of a hearth in at the least one Amazon warehouse. Wilding, the Fresno hearth inspector, concluded the blaze at FAT1 “originated on or near two inverters,” based on an investigation report obtained by CNBC via a request for public data.
Malfunctions and improper installations
Amazon blamed third-party companions and distributors for probably the most important issues uncovered by CEA and different groups engaged on services and sustainability initiatives.
“Over the past five years, solar malfunctions have been caused by improper installation techniques, improper commissioning of a new system, inadequate system maintenance and equipment malfunction,” the paperwork mentioned.
Amazon groups engaged on services and sustainability initiatives devised a two-part plan to assist stop future breakdowns within the rooftop photo voltaic program.
In late 2021, the divisions requested $3.6 million in funding to reinspect websites the place main findings had been recognized with a purpose to make sure the programs had been protected to be introduced again on-line, based on inside correspondence.
Internal groups additionally started to induce Amazon management to rely extra on salaried workers and fewer on exterior distributors. Over time, the corporate employed extra photo voltaic consultants centered on procurement, design, development and upkeep globally.
In some instances, administration was notably sluggish in responding. For instance, the teams inside the corporate agitating for change went to management for approval on the hiring, re-inspection and re-energizing plans. But the efforts had been held up for months by prime Amazon executives, together with Kara Hurst, vp of worldwide sustainability, and Alicia Boler-Davis, senior vp of worldwide buyer achievement, who left the corporate in June 2022, based on inside correspondence seen by CNBC.
Job openings recommend Amazon remains to be in search of to rent folks internally for photo voltaic operations.
The firm was just lately on the lookout for somebody to handle sustainability initiatives throughout its North American services, which embody rooftop photo voltaic. There’s a present itemizing for a technical program associate on the photo voltaic group says {that a} key side of the place is collaborating with “internal partners” in worldwide design, photo voltaic development and sustainability, amongst different divisions.
As it tries to employees up, Amazon has acknowledged that going inexperienced comes with hurdles, notably for a corporation “of the size and broad scope of Amazon.”
“But at Amazon, we don’t shy away from big challenges,” Hurst wrote, within the letter kicking off the 2021 sustainability report. “We don’t have all the answers today, but we believe in the need to act now.”
