Demand-Side Planning and Demand Response

Demand-Side Planning is the process of research and management of customer loads for more efficiently allocating supply resources. This typically includes load research, energy program design, implementation and evaluation and demand response applications. Demand response is designed to affect the load patterns of customers in a way that result in more efficient utilization of supply resources, including thermostat and switch load control, time-differentiated rates and information.

Lessons Learned and Evaluation of 2-Way Central A/C Thermostat Control System

This was presented at the 2005 International Energy program Evaluation Conference in NYC. The abstract is shown here, with a link to the complete paper below. (There’s a link to the conference presentation as well.)


Consolidated Edison Company of New York, Inc. (Con Edison), in cooperation with the New York State Public Service Commission (NYPSC) and other state agencies, has been working to address their growing summer peak, most recently through control of residential and small commercial Central A/C systems via a two-way system for thermostat control. Con Edison performed an assessment, implemented a pilot program and full-scale rollout of this technology, which communicates with the Central A/C thermostat via two-way pager, and enables features such as confirming feedback, recordable customer overrides, monitoring and thermostat access via internet by both customer and utility, utility control of either thermostat setpoint or duty cycle limit, and collection of hourly runtime and temperature data for virtually all units.

This paper presents background on the program, lessons learned, and impacts from the perspective of both the utility and the participants, including kW impacts and customer satisfaction.

Case Studies in Advanced Thermostat Control for Demand Response

This is a presentation I gave at the AEIC Load Research Conference – St. Louis, MO in July 2004, with updates included as of 2008.
