As part of its Smart Grid Demonstration Program project supported by the US Department of Energy, New York utility Consolidated Edison has deployed Alstom’s demand response management system (DRMS).
The project will help Con Edison manage its growing demand response activities and data within a single platform.
The solution, based on Alstom’s e-terraDRBizNet 3.0, provides utilities the digital intelligence to make fast decisions to compensate energy flow and optimize existing assets.
It can manage groups of aggregators and their resources, enabling Con Edison to reduce load within targeted overloaded areas.
The DRMS technology also provides the utility with advanced performance and settlement capabilities, measuring groups of aggregator resources’ performance and automatically applying the current tariff rules to calculate the payment for participating load reduction.
“This enables us to move more quickly,” said Andre Wellington, the project manager from Con Edison. “We anticipate fewer outages through increased network reliability and uptimes with DR’s availability. Additionally, the new demand response portal for enrollment and performance reporting will make it easy for our aggregators and customers to enroll and manage their DR resources, participate in events, and monitor their performance.”
Alstom’s DRMS integrates residential, commercial and industrial demand response programs and device technologies. It forecasts available load curtailment capacity and has been deployed with the capability to send signals for automatic load control to aggregators or directly to devices such as air conditioners or water heaters, thus optimizing the use of electricity. It then calculates customers’ normal electricity usage as a baseline, and then compares actual reduced usage to measure performance.
Con Edison’s demand response program
Con Edison's demand response programs currently have over 800 participating customers, according to the company’s website. A participating customer can possibly earn up to US$50,000 over a three-year period for every 100kW of load relief provided.
Two options are available – a 2 hour or less notification program (Distribution Load Relief Program), or 21 hour notification program (Commercial System Relief Program).
With the new platform more of Con Edison’s approximately 3 million residential customers are likely to become participants in these programs.
The deployment of the new platform also comes as Con Edison is launching a parallel demand management program to secure a permanent peak demand reduction of 100MW by June 2016. [Engerati-Con Edison Ups Storage Ante For Demand Management In New York]
