Non-Wires Alternative (NWA) is the inclusive term for any electrical grid investment that is intended to defer or remove the need to construct or upgrade components of a distribution and/or transmission system, or “wires investment”.
These NWA investments are required to be cost-effective compared to the wires investment and are required to meet the specified electrical grid need.
An NWA can include any action, strategy, program, or technology that meets this definition and these requirements.
Some technologies and methodologies that can be applicable as an NWA investment include demand response, solar, energy storage, combined heat and power (CHP), microgrid, conservation or energy efficiency measure, and other distributed energy resources (DERs) or distributed generation (DG). NWA projects can include these and other investments individually or in combination to meet the specified need in a cost-effective manner.
