The National Electrical Manufacturers Association on June 25 said it has “developed a clear, consensus-based blueprint that helps utilities and manufacturers implement interoperable, efficient, and scalable digital substations."
NEMA said digital substations represent a major advancement from traditional, analog systems. "By using real-time data, intelligent automation, and standardized communication protocols, digital substations enhance grid responsiveness, support the integration of renewable energy, and improve reliability for customers," ir said.
However, implementing digital substations presents integration challenges for utilities and manufacturers. Equipment from different vendors may not communicate effectively, and complex custom engineering can drive up costs and delay projects—just when speed and scale are most needed, NEMA said.
To address these challenges, NEMA has developed a blueprint that helps utilities and manufacturers implement interoperable, efficient, and scalable digital substations from the beginning.
NEMA’s Basic Application Profiles (BAPs) address fault location, isolation, and service restoration (FLISR).
NEMA said that taken together, these documents enable grid modernization, automation, and responsiveness and help reduce system losses, lower peak demand, and improve energy efficiency:
• BAP for FLISR in a Looped Single Line Feeder with Communications Loss (NEMA US 80061-2025)
• BAP for Fault Isolation including DER connectivity (NEMA US 80064-2025)
• BAP for FLISR in a Looped Single Line Feeder (NEMA US 80047-2024)
“According to NEMA’s “A Reliable Grid for an Electric Future,” electricity demand in the U.S. will increase 2% annually and 50% by 2050. Meeting that demand requires a smarter, more flexible grid—and digital substations are key to that transformation,” said Patrick Hughes, Senior Vice President, Strategy, Technical, and Industry Affairs, NEMA. “NEMA’s Basic Application Profiles (BAPs) are a foundational step in that direction, giving utilities the tools to deploy digital substations more quickly, reliably, and cost-effectively.”
NEMA represents over 300 electrical equipment and medical imaging manufacturers.
