In New York State (NYS), small commercial and residential customers have become significant contributors to local and system-level peak electric demand. This is primarily driven by the addition of air conditioning units, resulting in summer peaks. Urban areas such as New York City face challenges in making upgrades to distribution systems to serve these rising demands. Real estate is generally unavailable (or unaffordable) for new distribution substations, while increases in feeder capacity are difficult due to limited space in underground vaults and distribution channels. As a result, “non-wires” alternatives such as demand response (DR) are of particular interest.
This document identifies a set of DR use cases that are relevant to NYS utilities. The context for the creation of this document is a demonstration project funded by the New York State Energy and Research Development Authority (NYSERDA). This project involves the development and demonstration of an advanced air conditioning unit with built-in DR capabilities and an open standard communication interface. Specifically, this demonstration used a packaged terminal air conditioner (PTAC). These through-the-wall units are common in New York City and, together with window AC units, contribute significantly to summer peak loads.
The communication interface is based on the Consumer Electronics Association CEA-2045 modular interface standard. This standard defines a port into which communication devices of any technology can be plugged by the consumer. In this way, the PTAC unit may be integrated with any DR system and therefore have more potential for mass production.
The use cases identified in this document form the basis for the development of this interoperable DR-ready PTAC unit as well as the communication modules and systems used in its demonstration. These use cases are intended to be generically applicable to NYS utilities and end-use customers. The cases have been identified by a technical advisory group made up of representatives from New York utilities, manufacturers, research entities, and standards organizations.
