AlsoEnergy (PowerTrack) alternative for solar monitoring (2026)
AlsoEnergy no longer exists as a standalone company: it is Stem PowerTrack now. That transition, and the enterprise procurement that comes with it, is why operators comparison-shop.
AlsoEnergy was acquired by Stem, Inc. for 695 million dollars in a deal completed in February 2022, and its platform now runs as Stem PowerTrack, with the PowerTrack APM suite launched in September 2024 and roughly 36 GW of solar under management. It remains one of the strongest solar plus storage asset performance platforms, especially for C&I portfolios. Operators seeking an alternative usually want deeper independent analytics, lighter procurement, or public pricing; NuraVolt offers all three as a software-only layer on existing data.
What PowerTrack is, factually
PowerTrack is the former AlsoEnergy platform, historically one of the strongest C&I solar monitoring products and now the core of Stem’s software business. Stem announced the 695 million dollar acquisition in December 2021 and completed it on February 1, 2022; the deal added 32.85 GW of solar assets under management, and Stem cited around 36 GW in 2025. PowerTrack APM, launched September 2024, extends monitoring into asset performance management for solar plus storage, aiming to bridge technical and commercial operations. Context a buyer should know: Stem went through a hard 2024 to 2025 restructuring away from battery hardware resale toward software, including a workforce reduction of about 27 percent, and reported fiscal 2025 as its first full year of positive adjusted EBITDA, crediting the software pivot. The PowerTrack product remains actively developed.
Where PowerTrack wins
Breadth and pedigree in solar plus storage. PowerTrack spans commissioning through O&M across roughly 50 countries, with hardware integration depth built over two decades of AlsoEnergy history and storage capabilities reinforced by Stem’s energy-storage lineage. A portfolio owner running utility-scale solar alongside grid-scale batteries, who wants monitoring, controls, and commercial reporting under one enterprise contract, is PowerTrack’s target customer, and the platform’s scale claims are among the largest in the category. For large C&I fleets it remains one of the most proven platforms in the market.
Where the independent alternative wins
Three axes. Analytics depth per euro: NuraVolt’s center of gravity is the loss economics PowerTrack treats as one feature among many, per-inverter soiling estimation after digital-twin correction, fault classification with accuracy published as open benchmarks on public datasets, and BESS warranty, cycling, and revenue intelligence with modelled and measured numbers kept in separate lanes. Procurement weight: PowerTrack is an enterprise sale with quote-based pricing; NuraVolt publishes its pricing and onboards from existing data without a hardware or SCADA project. Independence: Stem is a storage company whose software grades storage-adjacent assets; an independent layer with no hardware interest produces the warranty and underperformance evidence an owner can take into a dispute. The honest converse: NuraVolt does not do plant controls, dispatch, or commercial invoicing, so a buyer needing those keeps an operations platform and layers analytics beside it.
