Enterprise DERMS:
One Platform from
Grid Edge to Markets

Utility DERMS
Distributed energy resources (DER) are now central to how utilities manage peak demand, defer capital, and meet reliability obligations. The question isn’t whether to deploy a distributed energy resource management system (DERMS) — it’s whether your DERMS can actually perform when it matters. Trust a DERMS that works.

The most-deployed DERMS
in North America

OATI pioneered the first DERMS in 2009. With more than 225 utilities using the platform, we remain the industry’s most-deployed DERMS. Join the utilities already unlocking flexibility, enhancing reliability, and deferring infrastructure upgrades.

OATI DERMS supports tactical and responsible Virtual Power Plant (VPP) growth, from the simplest grid edge programs to the industry’s only end-to-end enterprise platform.

For program managers: enrollment to settlement, on one record

A VPP starts with people — enrolling customers and aggregators, proving they performed, and paying them correctly. OATI DERMS puts all of it in one place for the program manager:

  • Define each program’s rules — when it can be called, activation constraints, and settlement terms
  • Give aggregators and customers a self-service portal to check eligibility, enroll, track status, and exchange documentation
  • Validate enrollments as they arrive, so only eligible, approved resources go live
  • Measure and settle automatically with a configurable baseline and settlement engine that scales to thousands of computations in minutes — and adapts when a tariff changes
For operators: see all of the data, decide, dispatch— with confidence

Operators carry the reliability burden and can’t afford blind spots. OATI DERMS brings ADMS, AMI, and IoT/SCADA data into one operational picture — the real value is uniting systems that don’t normally talk:

  • Spot violations fast with a geospatial heat map that flags overloads and voltage issues, with AI-assisted alarms
  • Forecast load up to seven days out and see exactly where VPP capability is needed
  • Decide with a live load curve — add or remove programs and resources and watch the peak respond, while the system tracks how many times each program can still be called so you never exhaust a resource
  • Act in real time during an event — notify thousands of customers and aggregators in minutes, watch performance live, and call additional programs if the response falls short
For market teams: turn distributed capacity into market revenue

Distributed resources are only as valuable as your ability to monetize them. OATI DERMS connects your portfolio to the market:

  • Pull in real-time and day-ahead prices and market load forecasts to see where the revenue is
  • Build a VPP manually or automatically, forecast its capability, and submit offers to the market
  • Reconcile and settle with confidence — verify meter data, flag what’s missing, complete every calculation, and adapt instantly when tariffs or market rules change
For executives: understand the big picture

Executives need to know the program is growing, performing, and paying off. OATI DERMS rolls the operation into one clear view:

  • Enrollment overview — totals by program, and the trend in sign-ups and opt-outs
  • Events — load forecast, available program capability, and what’s coming up
  • Performance — settlements pending, results from past events, non-performance, and savings achieved by program over time

Case Studies

  1. North Carolina co-ops leverage real-time DERMS for system-wide flexibility

    North Carolina’s Electrical Cooperatives needed a hosted, modular DERMS to support G&T visibility and cooperative-level control across 26 co-ops.
    Solution
    North Carolina’s Electrical Cooperatives use OATI real-time DERMS to create one dashboard for resource visibility, dispatch, and multi-channel event communications.
    NCEMC’s real-time DERMS evolution
    DERMS in and of itself allows for visibility and coordination of resources. Whether that’s for your portfolio, distribution operations, or entry into the market, you need to have the coordination to do all of that. We were searching for a vendor that could embrace that complexity. OATI DERMS is integral to our success in our Distribution-Operator Initiative. The tools it provides enables our team to continue to transform the grid.Senior Vice President of Power Delivery, NCEMC

  2. Con Edison’s surgical demand response with OATI

    Con Edison, a New York utility operating one of the most complex and densely populated service territories in the United States, faced multiple rising demands: electrification, diverse customer needs, and a unique urban grid. They needed an innovative solution to meet these demands and maintain reliability.
    Solution
    Con Edison deployed a demand response management system (DRMS) developed in partnership with OATI that has enabled automation, scalability, and real-time visibility. As a result, Con Edison experienced a 20-fold increase in customer program enrollments. Today, Con Edison manages more than 50 aggregators and makes 100,000 calculations every 15 minutes.

  3. TVA manages massive load growth with OATI DERMS

    In TVA’s service region, a new wave of growth in the C&I sector has disrupted the traditionally flat load growth, which could now be a relic of the past. As TVA’s portfolio continued to grow, the utility needed more scalability and automation in its solutions, which led to TVA selecting OATI in 2019 for its transition to DERMS.
    Solution
    TVA transitioned from an in-house DRMS to OATI DERMS to unlock the dynamic automation required by one of the nation’s largest demand response portfolios. With massive C&I growth in the region, TVA is collaborating with giants like Google and Amazon to optimize demand and drive innovation.

    We’re leveraging those [tech] partnerships to say, ‘Okay, this is what we can do with traditional infrastructure, how can we speed up the timeline, and is it a cost adder or is it a cost saver at the end of the day? How do we streamline the process whether we’re talking to Google or Amazon, or anybody at the end of the day so we can enable this for growth in the region?Senior Consultant of Strategic Initiatives, TVA

  4. Dairyland Power optimizes battery storage and DER with OATI DERMS

    One of G&T Dairyland Power’s member cooperatives installed battery storage, but the asset was isolated from Dairyland’s broader controls system, limiting the battery’s operational and market flexibility.
    Solution
    Dairyland Power used OATI’s IoT SCADA gateway to transform the previously isolated battery site into a grid-interactive resource without the need for costly retrofits, enabling seamless integration with Dairyland’s OATI DERMS platform.
