Total Grid Orchestration means bringing information, forecasts, and options together so people can coordinate decisions across the grid. It does not replace operators, planners, or existing systems. It helps them work from the same picture with a common framework for:
When TGO is in place, you can
- See the grid as one system. A shared view of conditions across generation, transmission, distribution, and behind-the-meter resources.
- Understand risk earlier. Analytics highlight where the plan is drifting toward reliability, cost, or operational risk.
- Know your options. Operators and planners can see which levers are available, and the tradeoffs of using them.
- Act with confidence. Decisions are informed by quantified risk instead of fragmented signals or assumptions.
How do we accomplish that?
We envision Total Grid Orchestration (TGO) as a System of Systems approach, not a replacement of existing operational, planning, market, and customer systems. It introduces a coordination layer that brings models and data from those systems into a shared context and aligns timing across real-time, near-term, and planning horizons.
TGO Concepts
The TGO layer maintains a unified view of the grid state, constraints, forecasts, and flexibility envelopes.
The TGO layer closes the gap between planning and operations by translating increased capacity into anticipated, operational outcomes. It provides shared data, assumptions, and constraints where planning informs the operational guardrails and operations provides feedback into planning through a common risk framework.
TGO can provide for operators:
- Early warning when the operating day is deviating from plan
- Ranked views of constraints and risks
- Clear visibility into available levers to alleviate risk
- Pre-approved playbooks and recommendations
TGO can provide for planners:
- Feedback on how assets and flexibility actually perform
- Ability to model operational reality, not just nameplate capacity
- Inputs that support non-wires solutions and avoided overbuild
- Planning processes informed by near-term risk and constraints
What TGO is not
A replacement of existing control systems (EMS, ADMS, DERMS)
A replacement of market systems
A new control room automation platform
A real-time autonomous control scheme
A smart grid 'digital transformation' program
If you work anywhere near the electric grid, you can feel it: the grid is changing faster than the way we plan and operate it.
Load is growing in new places. Weather is more extreme and less predictable. Customers aren’t just consuming electricity anymore, they’re generating it, storing it, and responding to price and reliability signals. At the same time, utilities are expected to keep reliability high, costs reasonable, and emissions moving down.
Reliability in a time of uncertainty
Utilities are being asked to deliver higher levels of reliability and resilience at the same time as managing significant cost pressure from grid modernization.
This creates a fundamental tension: modernization is necessary to maintain reliability, but traditional approaches (primarily infrastructure expansion) are increasingly too slow, too costly, and often inefficient.
Growth, capital constraints, and system complexity require tighter alignment across asset strategy, operations, grid planning, and digital investments in order to balance affordability with required grid investments.
Datacenters & Load Growth
Current grid risks are being exacerbated by spot load growth, alongside electrification, decentralization, and behind the meter adoption. These trends drive an exponential increase in supply demand variability that existing siloed planning and operating models cannot manage effectively, particularly across day ahead, day of, and near-term horizons. In this environment, the limiting factor is no longer just infrastructure—it is coordination, visibility, and risk management across systems.
Under sustained load growth, conservative assumptions and static operating limits increasingly translate into:
- Delayed interconnections,
- Accelerated capital spend, and
- Higher operational risk.
TGO is positioned as the mechanism to unlock existing grid capacity safely by aligning planning and operations through a risk‑informed, system‑of‑systems approach.
Through TGO, we can enable utilities to safely accelerate interconnections, manage near‑term operational risk, and maximize existing grid capacity while maintaining reliability.

Extreme Weather Events
Extreme weather events, major storms, winter extremes, and wildfire conditions, are exposing the limits of siloed grid operations by introducing fast‑moving, system‑wide risks that result in:
- Rapid shifts in load and generation balance
- Reduced operating margins
- Increased likelihood of outages and contingency events
- Operational decisions that must be made under high uncertainty
Without grid orchestration capabilities in place, extreme events can expose:
- Lack of end‑to‑end situational awareness
- Limited ability to stage resources proactively
- Inconsistent or manual decision‑making across operators
- Underutilization of flexible resources (DER, storage, demand response)
TGO is designed to address exactly this type of problem by enabling risk‑informed decision‑making, cross‑domain coordination, and proactive operations. TGO should enable integrated forecast-driven risk signals and provide visibility into tradeoffs between safety, load impact, and system stability.
Customer Behavior & DERs
Customers are increasingly adopting distributed energy resources (DERs) such as rooftop solar, battery storage, EVs, and smart devices, and are becoming active participants in the energy system. Without coordination, DER growth risks turning customers into unpredictable system variables, rather than valuable system resources. Challenges include:
- Increased variability in net load, driven by customer generation and consumption patterns
- Limited visibility into behind-the-meter resources, making planning and operations less certain
- Uncoordinated DER behavior, which can create local constraints rather than system-wide benefit
- Difficulty treating DER as reliable capacity, due to inconsistent participation and response
- Growing complexity in customer programs, tariffs, and incentives
- Need to balance customer choice with system reliability and affordability
TGO can support leveraging customer-side resources as dispatchable, verifiable load, enabling reliable integration of DERs into grid operations.
Accelerating TGO adoption
We are a utility-driven forum to foster collaboration and enable technological advancement. The Alliance focuses on turning vision into tangible work products.
We aim to drive practical direction and solutions for near real-time and real-time operational risks by supporting utility best practice adoption and evolving operating models, and informing vendor product capabilities.
Tangible Work Products
Our working groups are busy advancing TGO concepts with supporting frameworks, use cases, maturity models, and requirements.
It is our hope that these tools can be leveraged to advance TGO-enabling technology and accelerate grid modernization/orchestration initiatives.
Collaboration
The TGO Alliance creates a forum for communication and collaboration for both utility peers and utility-vendors. Members share insights into operational challenges, pilots, and lessons learned, helping to inform best practices, product roadmaps, and refine TGO concepts. Vendors bring visibility into current product capabilities and help to inform the TGO vision with key insights into data, architecture, integrations, and functional capabilities.
Thought Leadership
In addition to the objectives within our working groups, TGO members actively seek ways to elevate TGO concepts in the industry.
In addition to presenting at key industry events, TGO hosts an annual TGO Summit to share working group progress and collaborate in person.
2026 Working Groups
TGO Enablement Working Group is focused on defining what TGO is and how utilities operationalize it. They have built the foundational framework, capabilities, and use cases for TGO to ensure a common understanding and language for TGO.
This working group is actively developing a TGO maturity model and utility self-assessment tool which can be leveraged to prioritize and guide TGO/Grid Modernization investments. Ultimately, this working group aims to develop a TGO playbook for deploying TGO in real-world environments and share at the 2026 TGO Summit.
Grid Flexibility Working Group is focused on how flexibility is orchestrated in practice. Key focus areas include:
- Localized grid flexibility: coordinating DER, storage, and demand response to manage local constraints
- Large load flexibility: enabling flexible interconnection and operation of large loads
This working group has defined flexibility concepts, objectives, use cases, and requirements. They are working on a scalable flexibility framework and deployment approach that allows utilities to integrate DERs effectively, accelerate large-load connections, and reduce both capital and operational costs through coordinated flexibility. Progress from this group will be shared at the 2026 TGO Summit.
