Be part of the discussion among the architects of PLMA's Demand Response Training Series in defining the evolution of demand response. This definition will be used across the three demand response training courses produced by PLMA in mid-September in St. Louis. But you are invited to add editorial comments to help define an ideal industry vision for the fully-evolved state of demand response and identify the 10 most significant initiatives in the evolution of demand response.

Defining the Evolution of Demand Response

Posted By Tiger Adolf, PLMA, Wednesday, August 31, 2016

 

 

As PLMA refined and coordinated materials for the Demand Response Training Series, Michael Brown, NV Energy and Chair of the PLMA Education Committee, together with the Education Committee and PLMA Training Partners realized there was not a singular, agreed upon definition of Demand Response and the stages of its evolution (DR 1.0, 2.0, and 3.0) to help new and transitioning professionals, regulators, and lawmakers understand the growth and trends of the industry.  Their definition will be used across the three demand response training courses produced by PLMA in mid-September in St. Louis.  This topic was presented in a Demand Response Dialogue that included Michael Brown, NV Energy; Scott Coe; Ross Malme, Skipping Stone; and Stuart Schare, Navigant, on Thursday, September 1, 2016; 12:30-1:00 p.m. Eastern.  Listen to the recording of the DR Dialogue presented Sept. 1 www.peakload.org/event/DREvolve.

You are invited to add editorial comments to help define an ideal industry vision for the fully-evolved state of demand response and identify the 10 most significant initiatives in the evolution of demand response.  Be part of the discussion as the architects of PLMA's Demand Response Training Series articulate a definition for the evolution of demand response.

Defining the Evolution of Demand Response in the United States Electricity Industry 

PLMA invites member organization staff and the general public to help articulate an industry-accepted definition for the evolution of demand response within the United States electricity industry.  Below for your consideration and editorial comment is the definition to be used across the three demand response training courses produced by PLMA in mid-September in St. Louis.  In addition, this initiative invites comments to create a constructive dialogue to define an ideal industry vision for the fully-evolved state of demand response and identify the 10 most significant initiatives in the evolution of demand response.

 


Demand Response Evolution

 

DR 1.0 – The Past.  The beginning of demand response can be traced to the first interruptible tariffs for large commercial and industrial customers where utility staff called or paged a primary customer contact to manually change power consumption on-site with no immediate feedback in the utility control room, or the first one-way communication load-control devices installed on residential water heaters and air conditioners, or when wholesale markets were introduced to the US electricity industry. Then, demand response was primarily used to provide Energy (MWh) and/or Capacity (MW) when wholesale prices were unusually high, when there was a shortfall of generation or transmission capacity or during unexpected emergency grid operating situations. Notifications were typically manual day ahead or hour(s) ahead and the “system of record” for measurement and verification was usually the utility meter which was read on its regular cycle, often manually. There was little or no immediate customer feedback on performance during a demand response event.

 

DR 2.0 – The Present.  Demand response has become an integral part of most wholesale electricity markets and grid operation systems in the United States. Not only can demand response-driven initiatives provide more precise energy and capacity to support wholesale marketplace activities, but demand response can now also provide more sophisticated and near-instantaneous Ancillary Services such as non-spinning and spinning reserves and frequency and voltage support. Measurement and verification has become much more sophisticated and near real time measurements (either utility or non-utility) are often used as “system of record” for confirmation of customer performance during demand response events and for customer feedback.

  

DR 3.0 – The Current Path to the Future.  Demand response is evolving to be a component of broader distributed energy resources including distributed photovoltaic, electric vehicle charging, and various forms of energy/thermal storage both on a grid operating system scale as well as behind (i.e., on the customer side) of the meter. As a component of distributed energy resources, demand response can now provide a wide variety of service benefits both to the grid operator and to the customer (who may be a Prosumer who provides as well as consumes grid power) including volt/var control, renewable energy integration, and localized distribution system congestion management.  Where there are wholesale markets, demand response may have as its major underlying economic principle a price signal, which moves the industry away from traditional “command-and-control” mechanisms that will maintain a role for efficient grid operation.  In other words, DR 3.0 is not triggered directly by the utility or the system operator, but rather automatically by devices that react to pre-programmed price thresholds; however, a price signal will not be a requirement. Utilities may continue to rely on a grid signal such as voltage, rather than a price signal, for emergencies and system peaks or it may be valued related to costs (e.g., avoiding a CT start).

 

DR 4.0 – The Ideal Goal for the Future?  How would you define where the industry should be to fully evolve the promise of the potential of demand response?  Please take a moment to consider this issue and submit your constructive editorial comments to [insert link] so PLMA may share them with other thought leaders.

What are the 10 Most Significant Initiatives in the Evolution of Demand Response?

Help PLMA identify the 10 most significant events/activities in the evolution of demand response to enhance the Demand Response Evolution graphic above.  For example, should we include:

  • First utility-established interruptible tariff?
  • First load control device installed?
  • First opening of a wholesale electricity market?
  • First utility agreement with third-party for capacity curtailment?
  • [What would you suggest? Comment below.]

 

Listen to the recording of the DR Dialogue presented Sept. 1 www.peakload.org/event/DREvolve

All those who submit editorial comments and suggest significant initiatives will be invited to participate in an online PLMA poll to help select which initiatives should be added to the Demand Response Evolution graphic.
