Analytics and Control for Driving Capital Efficiency
Dominion Energy's Analytics and Control for Driving Capital Efficiency (ACDC) project will implement technologies to create a smarter, more adaptive electric grid. The project aims to improve control of grid functions, boost understanding of grid capacity, and inform infrastructure planning. ACDC is expected to deliver substantial improvements in grid reliability, operational flexibility, and cost savings, contributing to a more resilient and sustainable energy system.
The Grid Resilience and Innovation Partnerships (GRIP) Program
Through the Grid Resilience and Innovation Partnerships (GRIP) program, the U.S. Department of Energy's Grid Deployment Office is investing a historic $10.5 billion to enhance grid flexibility and improve the resilience of the power system. The GRIP program aims to accelerate the deployment of transformative projects to help ensure that all American communities have access to affordable, reliable electricity.
This project is being funded in part by the U.S. Department of Energy through the GRIP Program under the Smart Grid Grants section. Smart Grid Grants aim to increase the flexibility, efficiency, and reliability of the electric power system, with particular focus on increasing capacity of the transmission system, preventing faults that may lead to wildfires or other system disturbances, integrating renewable energy at the transmission and distribution levels, and facilitating the integration of increasing electrified vehicles, buildings, and other grid-edge devices.
The Analytics and Control for Driving Capital Efficiency (ACDC) project consists of four different technology-focused project scopes that will be deployed across our Virginia and North Carolina service territories.
Dynamic Line Ratings
Sensors installed on electric transmission lines in northern Virginia's congested circuits will collect data and provide a more accurate look at line capacity.
Grid Forming Inverter
A new type of inverter is being piloted to support renewable resource integration and enhance grid flexibility, building the foundation for renewable microgrid and system restoration capabilities.
Dynamic Performance Monitoring
Sensors installed at electric substations will collect grid frequency data, allowing grid operators to detect and mitigate grid instabilities before they impact service.
Grid Edge Visibility
Smart reclosers and control devices deployed across the distribution network will give operators granular control and situational awareness at the grid's edge, which is essential for managing distributed energy resources and restoring service quickly.

Community Benefits
ACDC will support Dominion Energy's commitment to providing reliable, affordable, and increasingly clean energy that powers our customers every day. The project will facilitate bringing new generation online and increase transmission capacity by deploying advanced grid technologies to unlock real-time operational flexibility. ACDC is expected to reduce congestion costs and facilitate the integration of renewable energy sources, reducing energy prices for consumers. Additionally, Dominion Energy has committed to engaging neighbors, communities, community-based organizations, and other stakeholders on project work and creating new jobs to support the project goals.
