This document discusses Con Edison's process for customers to obtain aggregated consumption data to support New York City's Local Law 84 benchmarking initiative. It provides an example of the data customers will receive, which includes a building unit summary and consumption totals. It also describes methods for extrapolating missing residential and commercial usage data, such as calculating estimated kWh for residential units based on the average usage per unit.

3. Support of Local Law 84
• Sound energy management is becoming more
important as buildings are beginning to manage their
carbon footprint.
• Con Edison is a supporter of Local Law 84 and has
taken several actions to support this benchmarking

4. Customer Process for Obtaining
Aggregated Consumption Data
• Customers may request aggregated consumption data from Con Edison
by emailing their requests along with a common area account number
associated with the building to citybenchmarking@coned.com.
– Please include the name on the account and the service address on
the request.
– If you are acting on behalf of the customer of record or requesting
tenant level data, please submit a letter of authorization along with
your request.
• The fee to obtain aggregated building consumption for up to 24 months of
electric and/or gas usage is $102.50 per building.
• Con Edison will send the requested aggregated building consumption
data by email to the address the request originated from within 15 days
after your payment has been processed.

7. Example on Extrapolating Residential Data
Formula: ((Total consumption / # of units) x # of Missing units) +
Total consumption
 Total consumption for the month = 212,455 kWh
 Number of bills issued during the cycle date = 220
 Units missing from the monthly aggregated consumption = 17
((212,455 / 220 = 966 kWh per unit) x 17 missing units) + 212,455 = 228,877
kWh’s for the billing period

8. Extrapolating Missing Commercial Data
• For missing commercial data a value chart will be
provided by the City of New York
– The values will be based on end use and provided
as a specific usage amount per square foot during a
specific time frame
– Once completed the benchmarking rule will be
available on www.nyc.gov/ggbp
