ERCOT Reactive Capability Review

A rule-by-rule power factor envelope verdict from the submitted capability curve, in place of a hand check.

About this module

What this module covers.

Automates the ERCOT Nodal Protocols Section 3.15(4) reactive-capability review for a Generation Resource or Energy Storage Resource (ESR) providing Voltage Support Service. From your submitted capability curve the workflow returns a deterministic power-factor-envelope verdict - the lagging and leading power factor envelope at maximum net power, rectangle coverage by resource type, the self-limiting anchor, and the low-MW structural rules - instead of hand-checking each criterion.

Dashboard capabilities

  • Automated Compliance Workflow for ERCOT Reactive Capability (Nodal Protocols Section 3.15(4))
  • Power-factor-envelope screening from a submitted capability curve

Support services

What GridStrong does inside this module.

  • Run the Nodal Protocols Section 3.15(4) checks on your submitted capability curve: the lagging and leading power factor envelope at maximum net power, rectangle coverage by resource type, the self-limiting anchor and the low-MW structural rules.
  • Return a cited verdict on each criterion in place of a hand check.

Final deliverables

  • Reactive capability review with a rule-by-rule power factor envelope verdict and its citations.

What we need from you

  • The capability curve submitted for the resource.
  • The resource type (Generation Resource or Energy Storage Resource) and its maximum net power.
