Field Study for EPRI P161: CEA2045 Standard Modular Communication Interface for DR

This supplemental project has been designed to provide utilities a means of working together in a coordinated fashion to test this concept in field environments. The goals of this supplemental project are: 1. To prove the performance of universal Consumer Electronics Association (CEA) 2045 communications port (comm port) 2. Convince manufacturers that the installation of a simple comm port is very low-cost, and makes their equipment easy to incorporate into any utility demand response (DR) program nationwide so that it could eventually become standard practice on all water heaters. If that can be achieved, then the question of whether or not a customer participates in a utility DR program becomes a simpler customer choice.
