Impacts to Meter Readers of Demand Response participating directly in the Energy Market

Price-Responsive Demand and Net Metering

2

Integrating Demand Response into the Energy Market starting on June 1, 2017

• Demand response will be integrated into the Energy Market similar to other supply resources. These changes require Demand Response Assets to be metered at the Retail Delivery Point– Retail Delivery Point is the point on the transmission or distribution

system at which the load of an end-use facility, which is metered and assigned a unique account number by the Host Participant, is measured to determine the amount of energy delivered to the facility from the transmission and distribution system

• Demand Response Assets can either provide:– Reduction of energy consumption from the power grid as measured

from the asset’s Retail Delivery Point– Net Supply (injection) of energy into the power grid as measured from

the asset’s Retail Delivery Point

3

Net Supply from Demand Response Assets will be treated just like generation in the Energy Market

• Net Supply associated to a Demand Response Asset will be assigned to a Net Supply Generator Asset

• A Net Supply Generator Asset has the same meter requirements as other Generator Assets– Required data to be settlement quality per metering requirements– Supplied within the 1.5 day submission deadline and adjusted through

the resettlement submissions– Supplied typically by Host Participant meter readers

Only one meter configuration impacts Meter Reader responsibilities

Mdra is the DDE meter providing 5 minute data (near real-time)

DG: M1 is hourly meter provided monthlyRTEG: M1 is the DDE meter providing 5 minute data (near real-time)

Mrdp is the billing meter providing Net Supply for settlement

Demand Response Provider are still responsible for providing a majority of the meter data

• Mdra measures the consumptions of the Demand Response Asset– Determined in 5-minute intervals by the DDE’s device receiving the

demand at the billing meter – Submitted by the Demand Response Provider in near-real time

• M1 measures the output of the Distributed Generation (DG)– Hourly meter data submitted to support the On-Peak or Seasonal Peak

performance• Provided by Demand Response Provider monthly

– 5 minute data submitted to support the RTEG performance• Submitted by Demand Response Provider in rear-real-time• Presently 2.5 day submission deadline (will change to 1.5 day) and

adjusted through the resettlement submissions

Meter Readers are responsible for providing metering for the Net Supply Generator Asset• Mrdp measures any Net Supply of an individual end-use

customer at the billing meter or the aggregation of individual end-use customers at the billing meter of the Net Supply Generator Asset– This will be submitted by the Host Participant meter reader for energy

settlement and will be used in the determination of the load within each meter domain
