ConEd Seeks OK To Suspend Of Provision Of Retail-Time Data To DR Participants With Legacy Meters
June 07,2019
Consolidated Edison Company of New York, Inc. filed at the New York PSC to modify its Plan for Providing Commercial Demand Response Data Access in a Manner That Supports Market Requirements and Customer Needs to suspend, starting in May 2020, the provision of near real-time data to participants in the ConEd demand response programs who have legacy meters, until AMI implementation is completed.
Consolidated Edison operates two demand response ('DR') programs for commercial customers to reduce electric
demand on peak summer days: the Commercial System Relief Program ('CSRP') and the
Distribution Load Relief Program ('DLRP') (together, the 'Programs'). The Public Service
Commission (the 'Commission') previously directed the Company to provide, 'data access in a manner that
supports market requirements and customer needs related to the DLRP.'
In response, through a
combination of legacy interval metering infrastructure and a Demand Response Management
System (the 'Current DRMS'), the Company provides near real-time interval meter data. The
Company is replacing this legacy interval metering infrastructure with Advanced Metering
Infrastructure ('AMI') technology (completion scheduled for 2022) that will provide customers
with near real-time data, which the Commission recognized when it approved the Company’s AMI business plan. The AMI meters will connect to the Company’s new Demand Response
Management System (the 'New DRMS') that will provide AMI-equipped customers with
reliable, near real-time access to their energy data starting in 2020.
ConEdison petitioned the Commission to approve the
Company’s proposed modification to its Plan for Providing Commercial Demand Response
Data Access in a Manner That Supports Market Requirements and Customer Needs to suspend
providing near real-time data to customers with legacy interval meters starting in May 2020
until AMI implementation is completed.
"The Commission should grant the Company’s request
because there is a high cost to maintain its systems for providing near real-time interval data for
the small number of participants that do not have access to their near real-time interval data but
that would prefer to use the Company systems for the data. Moreover, given the small number
of participants using the Company’s system for interval meter data, the Programs will not be
impaired if the Commission grants this modification," ConEd said
ConEd noted that the Company’s Programs require participants to reduce demand during network/load
area peak usage, emergencies, and scheduled tests. Participants use near real-time meter data to
assess their demand levels and make near real-time decisions that can positively affect their
performance in the Programs.
"Based on the Company’s discussions with energy service providers that aggregate participating customers into a portfolio ('Aggregators') and other
individual participants, most participants do not depend on the Company’s systems for their
participation. Indeed, participants can perform in the Programs without this information because
they do not require such data for successful participation or use their own data acquisition
systems to access their near real-time demand information," ConEd said
ConEd said maintaining the legacy system once the New DRMS is live would cost nearly $2 million
"The Company’s installation of AMI meters, expected to be completed by 2022, will
provide near real-time data for participants. Until then, participants are still able to participate in
the Programs but, to the extent they want near real-time data during events, most have developed
their own solutions until they receive their AMI meter. As described above, the Current DRMS
will require costly maintenance and upgrades to continue to provide the near real-time meter
data, which has little value due to the limited use by few participants. The Company has also
evaluated interim modifications to the legacy system and the New DRMS to allow the near real-time meter data to participants with legacy interval meters. However, the Company found that
option to be costly and possibly ineffective and untimely. Particularly in light of the ongoing
roll-out of the AMI meters, the Company considers either of these methods, upgrades to the
Current DRMS to continue to communicate with the legacy metering infrastructure or upgrades
to the legacy metering infrastructure to communicate with the New DRMS, are costly and
respectfully requests the Commission to approve modification of the Company’s Plan to suspend
the provision of near real-time access to legacy meter data until the full roll-out of the AMI
meters is completed," ConEd said
