Customers only pay for the electricity consumed, without incurring costs for the PV system components. Sunvigo's business model eliminates the complexity and high upfront costs associated with traditional solar system purchases or leases.
The company's smart solar-as-a-service solution maximizes the value of residential solar power systems by integrating them into a virtual power plant. This virtual power plant optimizes onsite solar power consumption and markets excess solar electricity within the Sunvigo community or to the power market. Sunvigo also offers battery storage, electric vehicle charging solutions, and a green grid power plan as part of its energy offerings.
Since its inception, Sunvigo has experienced rapid growth, increasing its customer base tenfold in 2021. By the end of 2023, the company had expanded its team to 130 employees and secured EUR 19.5 million in funding from investors such as Future Energy Ventures, Triodos Energy Transition Europe Fund, Eneco Ventures, Sparta Capital, High-Tech Gründerfonds, and Übermorgen Ventures. The raised capital will be used to scale Sunvigo's solar-as-a-service proposition and further develop its virtual power plant.

Swell Energy is a provider of virtual power plant (VPP) programs that aggregate and optimize distributed energy resources (DERs) such as rooftop solar and battery storage systems. The company's GridAmp software platform utilizes AI and machine learning to coordinate these DERs across the grid, intelligently meeting fluctuating energy demand. This helps utilities deliver cleaner and more reliable energy to customers while reducing dependence on fossil fuel peaker plants.
Swell partners with utilities, customers, and third-party service providers to create VPPs. Through these programs, customers receive bill savings, compensation (GridRevenue), and enhanced energy security. In return, their solar-powered batteries are integrated into a network that supports grid reliability, stability, and potential cost reductions for utilities.
As of November 2022, Swell had contracted 600 MWh of VPPs across 26,000 energy storage systems in homes and businesses throughout the US. These VPPs provide grid services in utility territories like Hawaii, California, and New York. In Hawaii, Swell's 80 MW VPP helps the utility maximize wind energy utilization by storing excess wind power in customer batteries.
In December 2022, Swell partnered with Sacramento Municipal Utility District (SMUD) to launch a residential VPP program aiming for 20 MWh and 10 MW of renewable capacity initially, with potential to scale up to 54 MWh and 27 MW.
In February 2024, Swell acquired residential and commercial solar installer Renu Energy Solutions, expanding its footprint across the Southeast and Mid-Atlantic markets. The combined company aims to drive innovation and provide tailored clean energy solutions through Renu's project development capabilities and Swell's financing and VPP technology.

Aquion Energy was a Pennsylvania-Washington D.C. based company that manufactured proprietary Aqueous Hybrid Ion (AHI) batteries and energy storage systems. These saltwater batteries used sodium ions and employed widely available materials like carbon, cotton, saltwater, and manganese oxide as the primary inputs. Aquion's technology was optimized for stationary and long-duration daily cycling applications such as off-grid systems, microgrids, energy management, and grid-scale energy storage. The non-toxic and safe nature of the batteries, combined with their ability to be fully discharged without harm, made them suitable for renewable energy integration and reduced reliance on fossil fuels. Aquion aimed to provide low-cost and sustainable energy storage solutions.
In March 2017, after facing financial difficulties, Aquion Energy filed for Chapter 11 bankruptcy protection and ceased operations, sales, and manufacturing. The company was subsequently acquired by a Chinese-affiliated entity, Juline-Titans LLC, for USD 9 million in June 2017. Following the acquisition, Aquion closed its Pennsylvania plant in September 2017 and reportedly moved operations to China with the new owners intending to scale up by targeting larger commercial clients.
