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.

ZOLA Electric is a leading emerging market energy technology company that aims to eradicate energy inequality globally. The company's roots trace back to Tanzania, where its founders observed communities lacking access to reliable and affordable energy sources, relying instead on dirty, expensive, and difficult-to-manage forms of energy like diesel, kerosene, and lead-acid batteries.Over a decade ago, ZOLA began by installing smart, connected lithium-ion batteries and solar systems to power basic energy needs such as lighting for rural communities. This approach of deploying networked, connected devices has driven the energy transition in emerging markets. Today, ZOLA has developed the world's first enterprise technology platform, purpose-built for energy access markets, combining a family of products controlled by a single operating system, ZOLA Vision.ZOLA's technology platform enables community-level electrification by facilitating localized solar energy production and providing smart technology with remote management tools. The platform is designed to deliver reliable, affordable, and clean power to the 3 billion people and hundreds of millions of businesses globally that lack access to it.Since its inception in Tanzania, ZOLA has expanded its operations to 10 countries across four continents, delivering affordable, reliable, and clean energy to over 2 million people, along with numerous schools, clinics, and businesses. In December 2022, the company launched its platform in Haiti, partnering with local renewable energy pioneer Haiti Green Solutions to address the country's energy crisis. This marked ZOLA's first market entry into North America.In November 2022, ZOLA commissioned a 120 kWp distributed solar mini-grid system in the Nyagatare district of Rwanda, providing power to over 1,000 homes, businesses, and institutions in the villages of Gakagati I and II. The project, developed using ZOLA's modular INFINITY technology, received support from organizations like Facebook (now Meta), the Shell Foundation, USID, and Endev.

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.
