Lithuanian Energy Tech Firm Sets Record in 2025 as Battery Storage Becomes New Standard

When I read that Lithuanian energy tech firm Inion Software reported record 2025 sales of 1.35 million euros—up from 1.22 million the year before—I didn’t just notice another quarterly earnings bump. I saw a signal flare going up for communities everywhere, including right here in Austin, Texas, where the same forces driving Baltic businesses toward energy storage are reshaping how we think about power resilience in our own neighborhoods. The numbers tell a clear story: storage isn’t optional anymore. It’s becoming table stakes.

What struck me most wasn’t just the revenue jump—though 10.7% growth in a single year is notable—but the explosive growth in connected assets. Inion Software saw platform-connected solar and wind installations leap from 255 in 2024 to 386 in 2025. Even more telling? The number of those projects paired with storage more than doubled, from 87 to 188. That shift mirrors what we’re seeing unfold across Texas, where ERCOT’s grid pressures and rising summer peaks are pushing both businesses and homeowners to glance beyond solar panels alone. They’re asking: how do I keep the lights on when the grid strains?

This isn’t abstract. Inion’s managing director, Dr. Šarūnas Stanaitis, pointed to three drivers: volatile electricity prices, growing state support, and improving interconnection conditions for storage systems. Sound familiar? Here in Austin, we’ve felt all three. Wholesale power prices spiked during 2023’s summer heatwave, prompting Austin Energy to launch new rebate programs for residential battery installations—specifically targeting systems that can export power back to the grid during peak events. Meanwhile, the city’s own Climate Equity Plan aims to achieve net-zero community-wide emissions by 2040, with distributed storage called out as a key enabler for reliability as we retire fossil fuel plants.

What’s happening in Lithuania offers a preview. Inion Software now monitors and manages 1,862 renewable installations totaling 829.7 MW—enough to power 300,000 to 600,000 households. That scale demonstrates how aggregated, intelligently managed storage can function as a virtual power plant, smoothing demand and enhancing grid stability. Austin’s own Pecan Street Inc., a research consortium based at the University of Texas, has been running similar microgrid trials in the Mueller neighborhood for years, proving that coordinated storage and solar can reduce peak draw on the main grid by up to 60% during critical hours.

The cybersecurity angle Inion highlighted is equally relevant. As more storage systems connect to platforms and the grid, attack surfaces expand. That’s why organizations like the Texas Department of Information Resources (DIR) have intensified their focus on securing critical energy infrastructure, issuing updated guidelines for operational technology (OT) environments that apply directly to behind-the-meter storage systems communicating with utility networks.

Given my background in energy systems analysis, if this trend impacts you in Austin—whether you’re managing a commercial property near Domain NORTHSIDE or considering upgrades for your home in East Austin—here are the three types of local professionals you need to vet carefully:

• Solar-plus-storage integrators with ERCOT market participation experience: Look for contractors who’ve successfully enrolled client systems in Austin Energy’s Value of Solar tariff or ERCOT’s ancillary services markets. They should demonstrate specific experience with lithium-ion or LFP battery configurations paired with inverters capable of grid-forming operation, not just basic backup. Request for proof of completed interconnection studies and performance data from similar installations in Central Texas.
• Energy attorneys specializing in Texas DER interconnection and incentive programs: These aren’t general practitioners. You need someone fluent in PUCT Substantive Rules §25.211 (governing interconnection) and the nuances of Austin Energy’s Solar Rebate Program, including recent changes affecting storage eligibility. They should track legislative developments at the Texas Capitol related to grid modernization bills and understand how federal IRA tax credits interact with state and local incentives.
• Cybersecurity consultants with NERC CIP and OT/IT convergence expertise: Discover professionals who understand that a home battery system isn’t just hardware—it’s a grid-edge device. They should be familiar with NERC CIP standards (even if not strictly applicable to residential scale, the principles matter), IEC 62443 for industrial control systems, and have practical experience securing Modbus/Sunspec communications between inverters, storage controllers, and energy management systems. Request references from work with Texas-based utilities or energy aggregators.
