Even because the coronavirus pandemic despatched the U.S. financial system into freefall this spring, the power storage trade delivered its second-best quarter ever by way of megawatts put in.

Regardless of social distancing orders, extra clients than ever earlier than added batteries of their houses to retailer solar energy and supply backup energy amid hurricanes, wildfires or different grid outages.

Residential storage corporations put in 48.7 megawatts/112 megawatt-hours in Q2, up 10 % from the earlier quarter, in accordance with the brand new Vitality Storage Monitor report launched Thursday by Wooden Mackenzie and the U.S. Vitality Storage Affiliation. That notches the fifth consecutive quarterly deployment document for residential storage, one thing that bigger battery segments have by no means achieved.

That’s shocking provided that residence batteries are virtually at all times offered as an add-on to rooftop photo voltaic, and the main rooftop photo voltaic installers took a success on gross sales in Q2 as face-to-face enterprise floor to a halt. A number of main installers noticed photo voltaic deployments drop by 20 % or extra from Q1 to Q2; residence battery installations bucked that development, led by development in California and Hawaii.

“Even because the photo voltaic market has slowed down barely, the pairing fee for storage continues to develop,” mentioned Daniel Finn-Foley, power storage director at WoodMac and an writer of the report.

Industrial and front-of-meter power storage exercise tends to swing wildly from quarter to quarter because of the small variety of tasks taking place in these markets. In Q2, industrial installations had been down, whereas front-of-meter installations surged.

That was largely as a result of one mission: the primary part of LS Energy’s Gateway battery got here on-line in June, including 62.5 megawatts to California’s grid. The developer stored going, and raised the mission’s energy capability to 250 megawatts within the third quarter, guaranteeing larger numbers for the following Vitality Storage Monitor to tabulate.

Gateway, plus tasks in Oklahoma and Massachusetts, helped push whole storage installations to 168 megawatts for the second quarter. That energy capability got here with 288 megawatt-hours of power storage, indicating a bent for shorter length tasks.

Ongoing building efforts promise an enormous second half to the yr, which analysts imagine will end in 2020 doubling the battery capability put in in 2019.

“The yr goes to shut out in a giant approach,” Finn-Foley mentioned. “We’re going to high a gigawatt of storage deployed yearly for the primary time within the U.S. market.”

2021 installations are on monitor to go three.7 gigawatts, he added, which might yield a 7x soar in comparison with 2019. 

The arrival of COVID-19 lowered the 2020 outlook by 500 megawatt-hours, nonetheless, within the earlier version of the ESM. On the time, industrial and industrial installations had been forecast to fall 44 %, and residential to drop 39 %, in comparison with pre-pandemic development expectations.

Residential storage exceeded expectations in Q2, regardless of essentially the most intense lockdown of the U.S. financial system. However general, slowdowns because of the pandemic have pushed the 2020 outlooks down by one other 200 megawatt-hours within the newest forecast. The market continues to be rising quick, simply not as quick because it was anticipated to absent a world pandemic.

The trade has a silver lining within the five-year forecast, although: the projected cumulative capability by means of 2025 grew 7 % because the final Vitality Storage Monitor, based mostly on new mission commitments.
