Medium-voltage UPS and energy management for AI data centers on Battalion Energy

AI data centers. Critical power at medium voltage.

Mon, 01 Jan 0001 00:00:00 +0000

Battery control between a changing compute load and the grid.

Battalion EMS

Mon, 01 Jan 0001 00:00:00 +0000

SITE CONTROL

One supervisory loop across the plant.

Battalion EMS is the site energy management system. Its supervisory loop runs once per second, coordinating plant dispatch and equipment limits. The medium-voltage uninterruptible power supply (UPS) has a separate UPS block controller for its local response.

Supervisory control and data acquisition (SCADA) runs on the EMS controller. It collects field values with their timestamps and quality, assigns command-point authority and records every tag in the on-site historian. Battalion Live receives the backlog when the wide-area link returns.

Modeling and optimization.

Mon, 01 Jan 0001 00:00:00 +0000

01 / ANALYSIS

01 / SITE VISIBILITY

One site. State and history together.

Battalion Live brings operating data into one workspace. The site dashboard shows photovoltaic (PV) power, battery state of charge (SOC), metered demand and inverter state across four-day timelines. Operators can read the present condition alongside the changes that led to it.

02 / NOTIFICATIONS

The alarm reaches the operating team.

Notification triggers connect a measured condition with the people responsible for it. For example, a low battery SOC alarm can notify a named group of operators.

03 / CONNECTED OPERATION

Engineering and integration.

Mon, 01 Jan 0001 00:00:00 +0000

01 / HARDWARE

Integrated skids and auxiliary power distribution.

Integrated skids bring the required equipment interfaces into a defined assembly. Auxiliary power distribution supplies the controls and supporting equipment, with two sources where the critical-power design requires them.

Control panels bring together sub-block controllers, network interfaces and power distribution. Controller pairing and power-source changeover follow the system availability design.

02 / INTERFACES

Protocol integration and plant control.

Battery management systems, power conversion systems (PCS), switchgear and meters need agreed data models and command priorities. Battalion develops equipment mappings, handles communication loss and checks control behavior before site operation.

Factories and industrial power.

Mon, 01 Jan 0001 00:00:00 +0000

Protect process loads and manage the industrial tariff.

Coincident-peak programs.

Mon, 01 Jan 0001 00:00:00 +0000

Size and dispatch for the intervals that set the charge.

Energence

Mon, 01 Jan 0001 00:00:00 +0000

THE PLATFORM

An energy intelligence platform, powered by Battalion's battery optimizer.

Energence is Battalion’s energy intelligence platform. It is powered by our battery optimizer, the engine that sizes, dispatches and values a battery against tariffs, market programs and battery life.

Behind it is what we have accumulated since 2016: more than 10 TB of market, grid and site data, covering more than 25 power markets across the Americas, Europe, Asia and Australia, with their market rules, a utility tariff database and live data streaming from the grid operators. AI price and load forecasting and bid optimization run on top.

Co-located generation.

Mon, 01 Jan 0001 00:00:00 +0000

Coordinate generation, storage and load at one connection.

Battalion SCADA

Mon, 01 Jan 0001 00:00:00 +0000

01 / FIELD DATA

Every value carries its context.

Battalion SCADA polls power conversion systems (PCS), battery management systems, meters, protection relays, remote input/output (I/O) and fire panel contacts over Modbus TCP and RTU. These are the network and serial forms of Modbus. It reads relays and remote terminal units (RTUs) over Distributed Network Protocol 3 (DNP3).

Every value carries a timestamp, quality, units and limits. That context stays with the measurement so the operator can distinguish a current reading from a stale or invalid value.

Microgrids and critical power.

Mon, 01 Jan 0001 00:00:00 +0000

Coordinate the island and hold the energy it needs.

Battalion power plant controller

Mon, 01 Jan 0001 00:00:00 +0000

01 / THE CONNECTION

Plant control follows the interconnection limits.

The point of interconnection (POI) is the boundary where the plant meets the grid. Battalion PPC controls active power, reactive power, frequency response and export limits at that boundary.

The plant command must fit both the interconnection agreement and the equipment available to deliver it. Battalion EMS coordinates the site through a supervisory loop that runs once per second.

02 / INVERTER GROUPS

Front-of-the-meter storage.

Mon, 01 Jan 0001 00:00:00 +0000

Connect market dispatch to local plant control.

Behind-the-meter storage and demand response.

Mon, 01 Jan 0001 00:00:00 +0000

Dispatch storage against the bill and the program.

Critical power for factories. Zero transfer time at medium voltage.

Mon, 01 Jan 0001 00:00:00 +0000

Keep the process line running through outages and sags, with 0 ms transfer.

Critical power for factories in Mexico

Thu, 08 Oct 2026 00:00:00 +0000

A factory in Mexico should plan for its grid supply to be interrupted. A battery-based uninterruptible power supply (UPS) at medium voltage answers that: it feeds the critical process through its own converter, with 0 ms transfer, so the line keeps running through an outage or a sag.

What the public record says

Mexico’s central bank asked manufacturers with more than 100 workers whether their regular electricity supply had been interrupted in the previous 12 months. In the south, 81.6 percent said yes. In the central region it was 55.0 percent and in the north 49.7 percent. The figures are from Banco de México’s regional survey, as cited in the BBVA Research and AMPIP nearshoring survey of September 2024.

ERCOT's proposed 10 MW power variation limit for AI data centers

Mon, 05 Oct 2026 00:00:00 +0000

ERCOT has proposed a power variation limit for large computational loads. The peak-to-peak change in a site’s active power, filtered to keep everything from 0.1 Hz to 55 Hz, may not exceed 10 MW in any rolling 5-second window. ERCOT presented the proposal to its Large Load Working Group in February, April and June 2026 and said it would file the revision request in the second quarter of 2026. As of October 5, 2026 no revision request carrying the limit appears in ERCOT’s list of pending requests, so the limit is a proposal and its final wording can still change.

Why data centers must now ride through grid faults

Mon, 05 Oct 2026 00:00:00 +0000

On July 22, 2026, at 7:56 in the morning, a 230 kV transmission line in Northern Virginia faulted. The protection cleared it as designed. Within about a minute, approximately 3,800 MW of data center load had moved off the grid and onto backup power, the largest load transfer PJM has recorded. PJM had seen similar events in the same area in July 2024 and February 2025, and this one was about twice as large.

Why your AI data center needs a battery

Fri, 02 Oct 2026 00:00:00 +0000

An AI data center presents two power problems at once. Graphics processing unit (GPU) and tensor processing unit (TPU) clusters can swing tens of percent of facility load in under a second, every 20 seconds or so, thousands of times a day. The grid sees those changes at the connection. The compute equipment also depends on continuity of supply. A voltage sag that trips rack power supplies forces training to restart from its last checkpoint.

THE PLATFORM

What you would be building on.

The platform is written in Rust and runs on real-time Linux at the site, where it controls batteries, power conversion systems, metering, protection relays, and microgrid controllers, and where it increasingly sits between the data center and the power system that feeds it. The architecture is modular: new capabilities are added as plugins and applications on a stable core, so the same platform serves a grid-scale battery, a critical-power microgrid, and an AI data center. It ships with an integrated user interface and connects to Battalion Live, which runs on AWS and handles telemetry, monitoring, and remote operations. Together they replace the SCADA and PLC control stack a conventional site would run, and they do more than that stack can: site control, power plant control, market dispatch, and monitoring in one system.

Battalion was founded by people who had spent their careers in energy storage, utility software, remote monitoring, and automation and controls. We had operated enough battery systems, and worked around enough of the EMS products on the market, to know what they got wrong. So we built our own, from the ground up. The result is a next-generation platform that our customers tell us is exceptional, and a team that people like working with.

Why Battalion. One team across the system.

Mon, 01 Jan 0001 00:00:00 +0000

01 / CONTROL

Control at the speed of the load.

The medium-voltage uninterruptible power supply (UPS) uses local block control. The UPS block controller takes 4,800 samples per second, decides in under 1 ms, with a 3 ms total response from measurement through command to the converter. On the dual-conversion path, transfer time is 0 ms because the load never leaves the inverter.

Every block runs local control and keeps serving load if the energy management system (EMS), the core network or the wide area network (WAN) is lost. Battalion EMS coordinates dispatch with a supervisory loop that runs once per second. Each UPS block maintains local control of its load.
