The Volt Harbor team will be at RE+ 2026 at the Las Vegas Convention Center from November 16 through 19, exhibiting MAC-BESS™ at Booth W17231. If you're a utility, an IPP, or a developer sizing data center power, we would love to see you.
RE+ is where the people financing, developing, and operating utility-scale and distributed clean energy actually gather. More than 40,000 of them will join this year. It's also where the data center story is now being told alongside the solar and storage story, because the two have become the same story. The grid is being asked to serve load growth it wasn't architected for, interconnection queues are stretching past four years in the biggest markets, and the people buying power at scale are rethinking what the physical layer underneath their projects needs to look like.
We think the next step-change in storage economics won't come from the cells. It is going to come from the layer around them: the power electronics, the switching, the controls.
MAC-BESS™ is our answer. It is a software-defined platform that integrates battery storage, advanced power electronics, switching, and intelligent control into a single, battery-agnostic hardware system. The entire front-end power stack, from the grid to the data center, in one product. In practice, that means:
40–50% lower capital and operating cost than a conventional BESS of equivalent capability.
50% less physical footprint on the project site.
Ultrafast energy response fast enough to ride through load and grid disturbances that would otherwise trigger backup generation or grid protection
Aerospace-level reliability with no single point of failure — field-replaceable units are hot-swappable with no interruption of operation.
Any input, any output. New LFP, sodium-ion, or second-life EV packs can all run inside the same system. The architecture handles heterogeneity through software, not constraints for matched batteries.
For the utility and C&I developers walking the floor
A storage project is a fifteen-year asset bought through a day-one procurement process, and the architecture you lock in at that moment decides almost everything that comes after. Systems that manage their batteries as a single block age at the pace of their worst modules, which is why most projects that get written down were effectively decided before commissioning.
MAC-BESS™ manages every battery module independently. That means degradation gets priced against the value of the energy in the moment rather than absorbed into the project. It means augmentation uses whatever battery is available at the time instead of whatever matches the original build. It means the asset you commissioned in year one is still the asset you own in year ten.
For the data center and hyperscale power buyers
AI workloads do not draw power the way the facilities were wired for. Thousands of computing accelerators synchronizing on the same job swing a facility from 30% to full rated capacity in seconds and back, repeatedly, in a pattern the legacy power stack was never designed to absorb. Equipment downstream registers every one of those swings. So does the utility upstream, which is part of why interconnection queues in major data center markets now run past four years.
The response so far has been to ask for more power, and to ask for it sooner. Neither one addresses the shape of the demand itself. MAC-BESS™ does. Storage that absorbs the spikes lets the grid supply the average, which means more compute behind an existing interconnection, or a smaller interconnection that clears the queue sooner. It also gives the utility a steady load profile to evaluate, and steady loads clear approval faster than volatile ones.

See you in Vegas.
