Founded in 1995, OATI deployed the energy industry's first cloud-based software solution.

In 2009, OATI introduced DERMS to harness the increasing number of distributed energy resources.

Today, we're building the first energy-native AI platform, OATI Genie, to transform power grid operations.

The grid runs on OATI.

30+ years of impact

Energy is all we do.

We’re power systems engineers with a track record
of driving major technology shifts in energy.

Since 1995, OATI’s innovative solutions have served as the backbone of utilities, grid operators, co-ops, and communities.

Today, more than 95% of North American reliability organizations trust OATI with mission-critical operations — including every major RTO and ISO on the continent — and the OATI distributed energy resource management system (DERMS) is the industry’s most-deployed smart grid platform.

About OATI

Trusted. Recognized.

OATI software tools are the backbone of power grid operations.

DER integration is no longer a distribution-level issue—it is now a cross-system challenge spanning utility operations, reliability standards, and wholesale market structures.

OATI’s central proposition is the ability to connect these layers through a single technology stack, enabling utilities to manage DERs locally while also coordinating participation in bulk-power markets. This end-to-end visibility is increasingly valuable as DER penetration accelerates and capacity pressures intensify

get more out of the grid.

AI Genie

Leveraging AI for enhanced efficiency and reliability on the California grid

California ISO grid operators used to spend countless hours reviewing transmission and generation outage data. Rising load growth fueled by electrification and data centers demanded a new approach.

Solution

OATI partnered with CAISO to implement Genie: an energy-native generative and agentic AI platform that improves processing speed, situational awareness, and streamlines workflows.

DERMS

Hawaii’s grid flexibility, powered by DERMS

Hawaiian Electric needed to manage increasing levels of grid-scale and behind-the-meter renewables and energy storage with limited fast-ramping generation.

Solution

OATI DERMS and the GridMind^® asset controller enable autonomous frequency response and dispatchable reserves from residential and commercial DERs, providing dynamic flexibility and deferring costly infrastructure upgrades for HECO.

Unlocking flexibility with DERMS

Microgrids & Asset Controls

Dynamic orchestration and resilience on the Atlantic coast

North Carolina’s Electric Cooperatives wanted to design a dynamic and resilient system capable of orchestrating behind-the-meter and grid-scale assets, including microgrids, energy storage, and solar farms in support of 26 member co-ops.

Solution

Using OATI’s real-time DERMS and the GridMind^® asset controller, NCEMC orchestrates reliable microgrids with automated islanding, demand response, and solar+BESS integration and optimization, as well as system-wide DER programs, providing system-wide resilience.

Microgrid & DER controls

Transmission & Reliability

Secure, reliable bulk power operations

FERC Order 881 mandated transmission providers implement ambient-adjusted ratings to improve grid efficiency and support unprecedented load growth. Many required year-long extensions in order to comply.

Solution

6 transmission providers successfully deployed OATI’s webLineR^® solution for AAR ahead of FERC’s original deadline, with some already pursuing real-time ratings as the next step of innovation.

Energy Markets & Risk

Real-time trading and compliance

APS needed to replace an aging ETRM system to address growing compliance pressures and support real-time energy trading across physical and financial markets.

Solution

OATI’s webCTRM suite enabled APS to comply with Dodd-Frank and FERC regulatory changes, automate trade capture, and integrate directly with OASIS and ICE Trade Vault.

Smart Meters

Right-sized smart metering for municipalities

Three cities in Illinois – Flora, Metropolis, and Breese – needed improved situational awareness and efficiency for their municipally owned utilities. However, small communities have historically been priced out of advanced metering infrastructure due to steep costs.

Solution

By adopting OATI’s IoT-based AMI solution and its modern, easy-to-install network of standards-based devices, these communities eliminated truck rolls, improved outage visibility, and created a communications network that can support additional smart city applications without further network investment.
