Non-Wires Alternatives for Distribution Systems: State Requirements and Engineering Practices

This tutorial, delivered at the IEEE PES Energy and Policy Forum in 2026, provides information on state requirements and utility engineering practices shaping the deployment of non-wires alternatives (NWAs) across the U.S. The tutorial provides information on:

• NWA process and a summary of state requirements related to screening criteria, cost-effectiveness evaluation, procurement options, contingency planning, stakeholder engagement, and regulatory oversight for delivering effective NWA solutions to grid needs.
• NWA practices and pilots across the country, exploring how utilities identify distribution system needs suitable for NWAs, evaluate technical feasibility, and integrate these solutions into distribution planning and operations.
