When the operators would call an event

PJM proposed adding reductions of eligible large loads to its emergency sequence. It emphasized that dispatchers still need discretion over the order of actions as conditions change.

Payment when a large load cuts demand

The August proposal permitted a retail rate from zero to half the non-performance charge rate. This was part of the proposed service; the registry that survived in October does not create that payment.

Responses and related views

Aggregate figures or individual projects?

Rep. Frank Pallone Jr. (New Jersey) · Direct response

Pallone wanted as much of the registry made public as possible to improve demand forecasts. FERC records his request separately from the states’ requests for protected access. He spoke as a member of Congress.

Pennsylvania asks to see curtailment data

Pennsylvania Public Utility Commission · Direct response

States need usable records to set retail rules

Organization of PJM States · Direct response

OPSI wanted meaningful state access to the registry to set retail curtailment rules and allocate costs. Its September comments distinguish the registry, which it supported, from the compensation mechanism it challenged.

Give customers a chance to correct errors

Equinix and PJM industrial customers · Direct response

Equinix wanted customers notified and allowed to verify or correct the information PJM would use. Industrial customers also requested an appeal and safeguards for commercial data.

Who answers for a supplier’s data?

Southern Maryland Electric Cooperative · Direct response

A registry cannot tell an operator what just tripped

Independent Market Monitor for PJM · Direct response

The market monitor distinguished enrollment data from real-time telemetry. It said PJM had not shown how it would measure an actual reduction in the proposed interim service.

PDF p. 18, ¶40

Corporate buyers oppose a uniform retail cutoff

Data Center Coalition · Direct response

The coalition supported letting customers bring their own generation but opposed the proposed interim service. It argued that PJM’s region-wide mandatory curtailment rule would displace state retail decisions.

PDF pp. 2–4

Consumer advocates tie curtailment to an alternative to the backstop

Joint Consumer Advocates · Direct response

The advocates saw value in a choice between contributing new capacity and curtailing with appropriate state action. With suitable eligibility rules, they argued, this mechanism would make a separate backstop procurement redundant.

Organization of PJM States, recorded member positions · Direct response

Delaware, D.C., Illinois, Indiana, Maryland, Michigan, New Jersey, North Carolina, Pennsylvania, Tennessee and West Virginia commissions supported OPSI’s comments.

Google asked FERC to separate the registry from mandatory interim service

Google · Direct response

FERC records Google’s request to accept the registry on its own. Google argued that getting better large-load data need not depend on approval of PJM’s wider curtailment and compensation design.
