Demand Response Call Times

February 6, 2016

The Con Edison Demand Response Commercial System Relief Program (CSRP) participating customers will be asked to reduce their loads for four hours, and notice shall be provided 21 hours in advance. The “call window” for all SC-11 rate customers is between 2 and 6 PM. Other Westchester County customer call times (for those not on SC-11 rate) will be per the schedule below:

11 AM- 3 PM: Cortlandt. 2-6 PM: Pleasantville and White Plains. 4-8 PM: Buchanan, Elmsford #2, Harrison, Mohansic, and Ossining West.

Bronx County customers not on SC -11 rate, the call windows are:

4-8 PM: West Bronx. 7-11 PM: Central Bronx, Fordham, Northeast Bronx, Riverdale, and Southeast Bronx.

The Nature of Technology – W. Brian Arthur

December 16, 2013

from Arthur, ” Technology expert James Newcomb, talking of the business of providing energy efficiency services, says: ‘ Doing it well entails knowledge of literally thousands of individual technologies, together with the capability to assimilate and optimally combine these technologies in patricular applications, taking into consideration interactive effects, control systems, process applications, and the differential economies of energy and demand savings. It’s the skill of a master chef, not a grocer’s buyer.’ “

Electric utilities make transmission and distribution investments. A shift to night-time use of this infrastructure by rate payers increases the utility’s return, as the transmission and distribution system is designed and sized for the daytime peak load. Load shifting is the common name applied to this concept.

Con Edison has started an excellent voluntary program called time of use metering. The utility reduces the kW-hour charge for night-time electric energy while raising the daytime kW-hour charge. The meter has to be switched out, the utility does this free. This is a good way to get return on investment for the customer as it is a savings realized with no capital investment on their part. A certain amount of rate analysis is required on the part of the customer to project the usage pattern for any one meter.

Generally the program would yield savings for stand-alone meters such as you find at a golf-cart facility or a municipal electric vehicle garage. Another application would be a thermal storage (ice plant) run from a chiller system operating at night, an application which would also realize a significant demand charge reduction.

Con Edison’s on-peak period is 8 AM to 10 PM Monday to Friday. The off-peak is all other hours.

SC9 time of use customer rate has a one-year term. SC2 time of use customers can go off the rate at any time.

Interval meters such as those for the ICAP and other demand response programs are not able to be used as time of use meters.

Con Edison’s time of use meter program is an economical step towards the “smart grid” much discussed today.
