Amazon buys 1.2GW Sunstone solar-plus-storage project from bankrupt Pine Gate

Global tech giant Amazon has been approved as the buyer of the 1.2GW Sunstone solar project in Oregon, one of the largest solar PV projects in the US.

The Sunstone site was developed and previously owned by Pine Gate Renewables, the US independent power producer (IPP), which filed for bankruptcy in November 2025. It includes 1.2GW of solar PV and 1.2GW of battery energy storage system (BESS) capacity, which is ready to build, having received permitting and approvals from the Oregon Energy Facility Siting Council (EFSC).

Amazon’s acquisition was approved by the Bankruptcy Court for the Southern District of Texas, which granted its offer of US$83 million in cash via its specific project subsidiary, Oregon Solar I.

The move follows Amazon’s complaints back in November that an Oregon utility was not supplying sufficient power to its data centre projects in the state, where it has built numerous cloud computing data centres close to the banks of the Columbia River. Once fully operational, the Sunstone solar-plus-storage project will be one of the most significant renewable energy generation projects in the US.

To date, most of Amazon’s energy procurement has been via power purchase agreements (PPAs), and along with fellow Big Tech leviathans Meta and Google, Amazon led US solar power procurement deals in 2024. But the scale of Sunstone, and the fact that it is ready to be built with approvals and permits in place, makes it an attractive proposition for a company whose growing energy demand will be a significant story in the industry over the coming years.

As the power demands of these data centre hyperscalers continue to grow, owning their own power sources might become more common. Last month, Google’s parent company Alphabet announced the acquisition of Intersect Power, an energy project developer, with a view to developing more energy capacity “in lockstep with new data centre load”, Sundar Pichai, CEO of Google and Alphabet, said at the time.

Since declaring bankruptcy, Pine Gate’s roughly 10GW of project assets have been offered to the market, though the company says it has sufficient liquidity to continue operating in the meantime. Earlier this month, Israel-based project developer Nofar Energy bought 1GW worth of Pine Gate’s utility-scale solar assets across the Carolinas, Alabama and Texas for US$285 million.

‘Rapid Growth but Disorderly Competiton’: Longi Enters Energy Storage Industry with PotisEdge Deal

We caught up with the president of system integrator PotisEdge following news of its acquisition by Longi, which marks the Chinese solar PV giant’s move into the energy storage industry.

News of Longi’s acquisition of PotisEdge first emerged on 13 November, with a public notice on the Shaanxi Provincial Administration for Market Regulation website. It revealed that Longi Green Energy Technology has agreed to acquire c.62% of PotisEdge via an equity acquisition, capital increase and voting rights, giving it sole control of the firm. Prior to the deal, PotisEdge was 44.79% held by individuals.

Longi and PotisEdge are characterising the deal as a partnership via which Longi will launch its ‘Energy Storage One-Stop Solution’, as it now covers solar, hydrogen and energy storage. Longi said its energy storage solution will be deployed first in key markets such as the UK, Germany, Italy, and Spain.

Longi VP Dennis She said in the announcement: “The current development stage of the energy storage industry is very similar to the early days of solar — confidence-driven rapid growth, but also bringing disorderly competition. The future dimension of competition in energy storage has evolved from ‘having the technology’ to ‘value reliability.”

PotisEdge president: Combination will offer opportunities

Speaking to Energy-Storage.news at an event in London marking the deal, PotisEdge founder and president Minjie Shi said: “Longi will bring the strong brand name and a big market to PotisEdge, and the combination of the two companies offers big opportunities to the market.”

“We are a technology company that designs and manufactures all the key components with the exception of the battery cells. We’re highly integrated, and that’s allowed us to gain a good reputation and solve market challenges,” Shi said.

“Battery cell manufacturing and system integration are totally different. Battery cells are a chemistry process, system integration is about controls, software, hardware and intelligent systems.”

Core technology offering

The firm’s offering is built around the five ‘S’s: BMS (battery management system), EMS (energy management system), PCS (power conversion system), TMS (thermal management system) and its proprietary ICCS (intelligent cell contact system) technology for predicting thermal runaway.

In September, the firm launched a 6.25MWh AC BESS product with string inverters and its ICCS technology for fire safety. The tech is designed for monitoring and protection of battery cells, to prevent thermal runaway and ensure safe operation of the system. It provides early warnings, predictions and an immediate response to potential cell malfunctions.

Before the AC launch, its grid-scale products were DC products. “Amongst the 12GWh of deployments, that has mainly been DC products, especially the 5MWh unit. Now we are shipping the all-in-one AC solution,” Shi said, adding that all regions are showing demand for both DC and AC products.

He added that the PotisEdge brand would remain for the foreseeable future, as it had over a decade of experience in the BESS industry with 12GWh deployed. It has mainly been active in the grid-scale segment, with deployments to date primarily in China, but also in North America, Europe and Australia.

Markets

“Europe is an important market for us, we’ve already delivered for a few sites here like Italy,” he said.

It has 31GWh manufacturing capacity from its facility in Suzhou, China, and a 4-6GWh one in Atlanta, Georgia, US, set to start manufacturing next year. The Atlanta facility will produce the same products as its Suzhou facility, but will be more automated, with only 100 employees needed, Shi said.

“For the US market, the main thing is to localise production, and we’ve focused on solving this for the last two years. All companies are facing that same challenge.”

PotisEdge is also working on a modular BESS solution, as many other system integrators and BESS manufacturers have done in response to transportation issues with ever more energy-dense and heavy 20-foot containers.

As part of its expansion into storage with PotisEdge, Longi will establish a Solar-Storage Technology Innovation Center Center of Excellence in Europe, it said.

Chinese solar PV companies have steadily moved into energy storage, seeking to capitalise on its growth opportunities but also to offset falling profits in their core market as the sector suffers from over-supply. See all coverage of Longi by our sister site PV Tech here.
