Power Grid Operator Exam Prep is an independent trainer for the four System Operator Certification examinations of the North American Electric Reliability Corporation (NERC): Reliability Coordinator (RC); Balancing, Interchange and Transmission (BT); Transmission Operator (TO); and Balancing and Interchange (BI). ONE BANK, FOUR CREDENTIALS All four examinations are drawn from the same six content domains and 31 knowledge areas; only the number of scored questions per area changes, and that table is published. Pick your credential and the whole app re-weights: your readiness estimate, your weak areas and how a mock paper is sampled. Every answer counts towards all four. SCORED THE WAY THE EXAMINATION IS NERC passes candidates on an absolute cut score, not a percentage: 92 of 120 for RC and BT, 76 of 100 for TO and BI. So the headline figure is a projected score out of the paper, and weak areas are ranked by how many scored questions they are costing you. MOCK PAPERS SAMPLED TO THE OUTLINE A mock paper draws exactly the number of questions the content outline lists for each of the 31 knowledge areas. Three hours, flag and return freely, no feedback until you submit, then a full review with an explanation and a reference on every question. NEW: THE CONTROL-ROOM SIMULATOR Take a shift at the BA, TOP or RC desk in nine scenarios, from a unit trip at the evening peak and an IROL exceedance against its Tv to EEA 3, a lost EMS, voice paths down and an evacuated control room. One model runs the system and the clock stops at each decision: read the live displays, choose what to do or answer a three-part communication, then watch it play out. The debrief counts, never as a percentage, the obligations you met or missed against the standards' own clocks, and explains every decision. Every number is tagged as a NERC figure, a value your company or RC sets, or a model assumption. New numbers every run. GENERATED DISPLAYS, NEW EVERY TIME • a six-bus one-line with flows, ratings and an N-1 contingency analysis report: find the worst contingency and decide what it obliges you to do; • a Balancing Authority AGC control board, with the ACE left for you to calculate. Plus twenty calculation drills with worked solutions. 1,224 ORIGINAL QUESTIONS Written from the freely published sources (the content outlines, the NERC Glossary of Terms and the enforceable Reliability Standards) and checked again by a separate pass. Each carries NERC's cognitive level: recall, application or analysis. FREE TO START, ONE PRICE FOR EVERYTHING Try it free: 50 practice questions in any mode, one full mock paper, one simulator run of any scenario, and every Library card. Full Access is a single in-app purchase that unlocks every question, unlimited mock papers on all four credentials, every trainer and all nine scenarios. One-time, no subscription, on your iPhone, iPad and Mac. ALSO INSIDE • 31 Library reference cards: seven must-know numbers and a short essay each • Choose an answer, then confirm it to see the explanation and its reference; A–D, 1–4 and Return work on a keyboard • Spaced repetition brings back what you miss • Works offline, and syncs through your own iCloud. No account, no data collected. • Light and dark, with a manual override for a night shift NOT AFFILIATED Power Grid Operator Exam Prep is an independent study aid. It is not affiliated with, endorsed by, or connected to the North American Electric Reliability Corporation, its Regional Entities, or Pearson VUE. NERC, the credential names and the examination codes are used only to identify the examinations this app prepares for. All content is original work. The simulator is a study aid: it is not approved by NERC and grants no continuing-education hours. Reliability Standards are revised regularly.
