degree of certainty. NERC currently collects Direct Load Control and Interruptible Demand
as part of its seasonal and long-term reliability assessments.
The following categories10 of D2
R were considered as part of the DSMTF effort:
Dispatchable Controllable Demand Response (DCDR)
• Capacity
1) Direct Load Control
2) Interruptible Demand
3) Critical Peak Pricing with Control
4) Load as a Capacity Resource
• Ancillary Load Reduction Acting as Capacity
1) Spinning Reserves
2) Non-Spinning Reserves
3) Regulation
• Energy-Voluntary
1) Emergency
Dispatchable Economic Demand Response (DEDR)
• Energy-Price
1) Demand Bidding and Buy-Back
The DCDR dispatchable resources provide an active tool for load-serving entities, electric
utilities or grid operators to manage their costs and maintain operational reliability.
Therefore, the DSMTF recommends:
Phase I: Data collection for both historic/forecast DCDR
DEDR can be ‘bought-through” by the end-user, and therefore, a less reliable resource
influencing reliability. Therefore, the DSMTF recommends that it be collected in the next
phase.
Phase II: Data collection for both historic/forecast DEDR
Non-Dispatchable Demand Response (ND2
R)
ND2
R link prices in retail and wholesale markets. Retail consumers obtain a price signal
reflecting the costs of production and delivery providing a signal to deploy resources more
efficiently. This characteristic, as ND2
R is generally tailored for mass markets, has the
potential to reduce or shape electricity use and overall costs.
