Interconnection Management Modernization

Client: Independent System Operator

Overview

The Independent System Operator (ISO) responsible for managing the regional transmission grid and coordinating interconnection requests for new generation and large load connections.

The ISO supports a wide range of stakeholders including:

  • Generation developers
  • Transmission owners
  • Utilities
  • Large energy consumers
  • Grid planning and engineering teams

With the rapid expansion of renewable energy and electrification, the ISO needed to modernize its interconnection management process to support a dramatically increasing volume of applications.

Challenge

The ISO faced significant operational and process challenges due to the rapid growth in both generation projects and large load requests.

1. Interconnection for Generation

The rapid expansion of Distributed Energy Resources (DERs)—including solar, wind, and battery storage—resulted in an unprecedented number of interconnection applications.

Key issues included:

  • A legacy “first-in, first-out” queue model that slowed project approvals
  • Large backlogs of projects waiting for study and approval
  • Manual workflows that created operational bottlenecks
  • Limited visibility for developers into application status and next steps
  • Increasing regulatory compliance requirements requiring auditability and traceability

The existing systems were not designed to support the scale and complexity of modern interconnection queues.

2. Connection for Load Growth

In parallel, the ISO saw a surge in requests for new load connections driven by:

  • Electric vehicle charging infrastructure
  • Building electrification
  • Industrial expansion and data centers

These requests required coordination across multiple internal teams and external stakeholders.

Challenges included:

  • Fragmented communication between planning, engineering, and customer teams
  • Lack of centralized project tracking
  • Slow approval cycles impacting customer timelines
  • Limited transparency into project portfolios and upcoming decision points

Solution

To address these challenges, the ISO implemented a modern interconnection management platform designed to streamline and automate the entire lifecycle of interconnection requests.

The solution introduced a new interconnection processing model that shifted from the traditional “first-in, first-out” approach to a “first-ready, first-out” framework. This allowed projects that were complete and ready for study to move forward without being delayed by incomplete applications ahead of them.

Core Platform Capabilities

Centralized Interconnection Management

  • Single platform for managing new service requests from application through construction

Portfolio Management

  • Developers and stakeholders can track and manage multiple projects in one place

Automated Workflow and State Management

  • Automatic project state transitions
  • Reduced manual administrative work

Real-Time Project Visibility

  • Dashboards showing project status, timelines, and upcoming actions

Stakeholder Collaboration

  • Shared access for planners, developers, and transmission owners

Notifications and Alerts

  • Email and system notifications for required actions and milestones

These capabilities created a transparent and collaborative environment where all parties could access the same real-time project information.

Technology Approach

The solution focused on process automation, transparency, and collaboration, enabling the ISO to manage a significantly higher volume of projects without increasing administrative overhead.

Key design principles included:

  • Workflow automation to reduce manual processes
  • Digital collaboration tools for stakeholders across organizations
  • Real-time reporting and dashboards for operational visibility
  • Automated notifications to ensure timely actions
  • Audit-ready data tracking for regulatory compliance

The platform serves as a centralized hub for managing the interconnection lifecycle while improving coordination across planning and engineering teams.

Results

The new platform delivered measurable improvements in operational efficiency and stakeholder experience.

Operational Improvements

  • Reduced manual processing through workflow automation
  • Improved queue management using the first-ready, first-out model
  • Faster coordination between internal teams and external stakeholders

Improved Transparency

  • Real-time visibility into project status
  • Clear tracking of decision points and upcoming actions
  • Improved communication across the interconnection ecosystem

Scalability for Future Growth

  • Supports growing volumes of renewable generation projects
  • Enables faster processing of large load connection requests
  • Provides a scalable framework for ongoing grid modernization

Business Impact

By modernizing its interconnection management process, the ISO significantly improved its ability to support the evolving energy landscape.

The platform now enables:

  • Faster interconnection approvals
  • Improved stakeholder collaboration
  • Greater regulatory compliance and traceability
  • A scalable system capable of supporting the continued growth of renewable energy and electrification

This transformation positioned the ISO to efficiently manage the next generation of grid expansion and energy transition initiatives.
