The Generator Owner (GO) is the entity that owns and maintains generating Facilities. Its NERC obligations are largely about the equipment: how protection is set, coordinated and maintained; how the plant is modeled and verified; how its equipment is rated; and how it is prepared for extreme weather.
The Generator Operator (GOP) is the entity that operates those Facilities and performs the functions of supplying energy and reliability-related services. Its obligations are largely about operation: following voltage schedules and Operating Instructions, communicating with the Transmission Operator and Balancing Authority, reporting events, providing real-time data and training operating personnel.
Many organizations hold both functions for the same plant. Others split them — an asset owner registered as GO while an affiliate or O&M provider is registered as GOP — or share them through a Joint Registration Organization (JRO) or Coordinated Functional Registration (CFR). Each arrangement changes who must produce which evidence, and every requirement needs a named owner.
The GO proves the plant is engineered correctly. The GOP proves it is operated correctly. Where one entity holds both, the evidence still has to be organized function by function.
Applicability varies with technology, size, interconnection voltage and registration category. Our programs are built around the specific plant, not a generic checklist.
Coal, gas steam and biomass units: excitation and governor model verification, PRC-019 coordination, PRC-024 settings, PRC-025 load-responsive relays and PRC-005 maintenance.
Multi-unit CT/CCGT blocks with shared GSUs and auxiliaries: unit-by-unit capability testing, model verification, cold-weather preparedness and blackstart roles where designated.
Governor and excitation modeling, capability testing and protection coordination for conventional hydro and pumped-storage units operating in both modes.
Transmission-side engineering that supports interface coordination — switchyard protection, ratings, studies and data — where NUC-001 interface requirements apply. Plant nuclear-safety programs are outside our scope.
Inverter-based resources (IBRs): plant controller and inverter model verification, ride-through settings and performance, disturbance monitoring and EMT models.
Solar-plus-storage and wind-plus-storage facilities where aggregation, shared POI equipment and combined controls change applicability and modeling.
Non-BES IBRs of 20 MVA or more aggregate at 60 kV or higher now captured by the expanded registration criteria. See our IBR Category 2 page for the full phased program.
Generator owners also registered as TO (and sometimes TOP) for generator interconnection facilities, and portfolio owners with GO/GOP across several Regional Entities.
In GO/GOP compliance the engineering work product is the compliance evidence.
A generator that owns its gen-tie line, collector substation or POI switching station may have obligations beyond GO/GOP — and in some cases a TO or TOP registration. FERC Order No. 785 and the NERC registration criteria address when generator interconnection Facilities create TO/TOP obligations; the answer depends on configuration, ownership and use. Where they do, standards such as FAC-001, FAC-003 and TO requirements under the PRC family may apply to those Facilities.
We map each element — collector system, main power transformer, gen-tie, breakers and protection — to the function that owns it and the requirements that follow.
The 2026 CMEP Implementation Plan highlights the "aggregation of control": unregistered third parties increasingly operate many Generator Owners' facilities from common control centers. A shared operations desk can dispatch dozens of plants for different owners without itself being registered.
Contracting out operation does not move compliance responsibility. The registered GOP remains accountable for voltage-schedule compliance, communications, event reporting, data provision and training — so contracts, procedures and evidence ownership need to be explicit.
This table lists the Operations & Planning standards most commonly applicable to GO and GOP registrations and the engineering evidence that typically demonstrates compliance. Applicability depends on your facilities, technology, size, region and registration category, and several standards are phased in or have multiple versions in effect. Confirm current versions, effective dates and applicability for every facility — our registration and applicability assessment does exactly that.

| Deliverable | Purpose |
|---|---|

| Gap | Why it matters |
|---|---|
| Settings evaluated at design, never after commissioning | Field changes, firmware updates and inverter replacements leave PRC-024, PRC-025 and PRC-029 evaluations describing a plant that no longer exists. |
| Models not updated after plant changes | Controller tuning, augmentation and repowering change behavior; MOD-026, MOD-027 and MOD-032 evidence has to follow. |
| Evidence held by the EPC or OEM | Test reports, settings files and models often never transfer to the owner at COD. |
| Unclear GO/GOP split | When an affiliate or O&M provider operates the plant, nobody is sure who owns VAR-002, COM-002 or EOP-004 evidence. |
| Incomplete PRC-005 inventory | Missing DC supply, communications or sudden pressure relay components mean missed intervals. |
| Ratings that stop at the generator | FAC-008 ratings must cover the equipment through to the POI, including the main power transformer, gen-tie and switching equipment the GO owns. |
| Cold weather plans without follow-through | EOP-012 evidence needs implemented freeze protection and tracked corrective actions, not just a plan document. |
The 2026 ERO Enterprise CMEP Implementation Plan names the following O&P requirements under risk elements that commonly touch GO/GOP registrations. Requirement numbers are quoted as listed in the plan; not every listed requirement applies to every GO or GOP, so confirm applicability for your functions and facilities.
| Risk element | Standards & requirements named | What it means for GO/GOP |
|---|---|---|
| Grid Transformation | MOD-025-2 R1–R3; MOD-026-1 R2, R6; MOD-027-1 R5; MOD-032-1 R1–R4 (Category 2 IBRs from May 15, 2026) | Capability testing, model verification and planning data — including newly registered Category 2 IBRs |
| Grid Transformation | PRC-024-3 / PRC-024-4 R1, R2 (PRC-024-4 effective Oct 1, 2026); PRC-027-1 R1–R3; PRC-005-6 R3, R5 | Ride-through settings tracked by version and unit; coordination and maintenance evidence |
| Grid Transformation | FAC-001-4 R1, R2; FAC-002-4 R1, R2 | Applicable GOs' interconnection requirements and study coordination for new or modified Facilities |
| Facility Ratings | FAC-008-5 R6 | Ratings consistent with the documented methodology for equipment the GO owns |
| Extreme Weather Response | EOP-012-3 R1, R3–R7; FAC-003-5 R6; EOP-011-4 R1, R2, R3, R6 | Cold weather preparedness and corrective actions; vegetation inspections for applicable GO lines; operating plans set by TOP, BA and RC that the GOP must support |
| Communication Protocols | COM-002-4 R1, R4, R5, R7; IRO-001-4 R1 | Named requirements mainly address issuers of Operating Instructions; GOPs should confirm their own receipt-side and compliance obligations are documented |
The aggregation-of-control concern is aimed squarely at generation. If a third-party center operates your plant, 2026 is the year to make responsibilities and evidence ownership unambiguous.

The Generator Owner owns and maintains generating Facilities and is responsible for equipment-related requirements such as protection settings, maintenance, model verification and ratings. The Generator Operator operates those Facilities and is responsible for operating requirements such as voltage schedules, communications, event reporting, data provision and operator training. One entity may hold both functions, or they may be split.
Many standards apply to both, but not identically. Inverter-based resources have specific standards such as PRC-028, PRC-029 and PRC-030, and model verification and data requirements reflect plant controllers and inverters rather than exciters and governors. Some synchronous-specific requirements do not apply to IBRs. Applicability must be confirmed plant by plant.
Only if they are registered as such. The registered entity remains responsible for the requirements of its registered functions. Operating agreements should state who performs each task and who retains the evidence, and a JRO or CFR can formally divide responsibilities where appropriate.
The plan notes that unregistered third parties increasingly operate many Generator Owners' facilities from common control centers. Owners and registered GOPs should make sure responsibilities, communications and evidence ownership for every plant the center controls are clearly documented.
In some cases, a generator's interconnection Facilities — such as a gen-tie or POI switching station — can create Transmission Owner obligations, depending on configuration, ownership and use. We assess each element against the registration criteria and applicable FERC and NERC guidance and document the basis for the decision.
PRC-005 maintenance programs, PRC-019 coordination, PRC-024 settings, PRC-025 relay loadability and PRC-027 coordination are common for synchronous plants. For IBRs, PRC-024 and PRC-029 ride-through, PRC-028 disturbance monitoring and PRC-030 performance analysis add significant scope.
MOD-026 and MOD-027 set verification periodicities and also require re-verification or updated data after certain equipment or setting changes. MOD-025 sets its own testing periodicity. Confirm the current versions and your Transmission Planner's requirements, and track change triggers so verification does not lapse.
The 2026 CMEP Implementation Plan lists PRC-024-3 and PRC-024-4, with PRC-024-4 effective October 1, 2026. Settings evidence should show which version applied to each unit on each date. Confirm the implementation plan for your specific units.
