FERC Order 2023 changed the rules

Prove your site control or lose your queue position

Only 13% of projects that enter the interconnection queue reach commercial operation. FERC Order 2023 just raised the bar — site control demonstration is now required at every queue milestone. Projects that can’t prove compliance get withdrawn automatically.

77%

of interconnection requests withdraw before completion

13%

of queued projects reach commercial operation

5 yr

median time from queue entry to commercial operation

High interconnection costs, extended timelines, and cascading restudies drive most withdrawals. FERC Order 2023 adds a new filter: projects that can’t demonstrate site control at each milestone now get withdrawn automatically.

Why now

Before FERC Order 2023, you could enter the interconnection queue and figure out site control later. Under the new cluster study process, you must prove commercial readiness upfront — including complete site control documentation. Submitting with gaps means rejection and lost queue position.

Every RTO is now enforcing stage-specific coverage thresholds. PJM requires 50% at application, 100% at IA execution. CAISO excludes options entirely at cluster study. MISO requires 75% at DPP Phase 1. The compliance bar went from "demonstrate good faith" to "prove it or lose your spot."

The requirements got harder. The penalties got steeper. And most developers’ site control processes haven’t caught up. No existing land management platform runs stage-aware coverage audits with the 5 filters RTOs actually check.

Built for mid-market renewable developers

If your team manages 5–50 projects across multiple RTOs, you're in the gap: too many parcels for spreadsheets, not enough headcount for a dedicated compliance team.

The problem

FERC Order 2023 made site control a hard compliance gate. An expired option, a missing signature, or an incomplete BLM permit can now get your project withdrawn automatically — and most teams find out too late to fix it.

Options expire before milestones

An option-to-lease expires 60 days before IA execution. Coverage drops below threshold. Nobody catches it until the RTO rejects your filing. Cost: queue position + deposit forfeiture.

Thresholds change by stage and RTO

PJM requires 50% at application, 100% at IA execution. CAISO requires 90% at cluster study. Spreadsheets can't track stage-aware rules across 7 markets. One wrong number = rejected filing.

Unsigned owners block coverage

One natural-person owner who hasn't signed disqualifies the entire parcel. A single missing signature can drop your coverage below threshold at filing time. You won't know until the audit runs.

How it works

Four layers of hard engineering that you can't replicate in a spreadsheet.

Document parsing

Upload lease PDFs. AI extracts legal descriptions, instrument types, expiration dates, option deadlines, and owner signatures from unstructured legal documents.

Cadastral matching

PostGIS matches metes-and-bounds and lot descriptions against county cadastral boundaries. Overlaps, gaps, and encumbrances are flagged automatically.

RTO rule engine

Each RTO has different thresholds at each stage. The rule engine validates coverage against the exact requirements for your current study phase — across all 7 markets.

5-filter audit

Active status, instrument eligibility, encumbrances, owner signatures, and BLM ROW status — checked per stage. Pass or fail, with every exclusion documented.

What you get

Know if your application will pass before you submit it

A 5-filter coverage audit checks active status, instrument eligibility, encumbrances, owner signatures, and BLM ROW status against your RTO's per-stage thresholds. Every excluded instrument and reason is documented.

Never discover an expiration gap after it's too late to cure

12 alert types including expiration countdowns, option conversion deadlines, coverage-below-threshold warnings, and instruments that expire before your next queue milestone. Alerts fire at 365, 180, 90, 60, 30, and 7 days out — because options signed in 2021 are expiring into post-Order 2023 milestones right now.

Submit the exact format your RTO reviewer expects

Generate RTO-formatted compliance packages with parcel coverage, instrument detail, exclusion justifications, and BLM/encumbrance status. CAISO GIP format built in; additional RTO formats generated on request.

Audit-ready history for compliance reviews and due diligence

Every instrument change is an append-only event. Every coverage snapshot is immutable after creation. Full history for compliance reviews, due diligence, and RTO audit requests.

Why trust Zonevex

PostGIS

All spatial operations run in PostGIS — the same engine used by national mapping agencies. No spreadsheet geometry.

7 RTOs

PJM, MISO, CAISO, ISO-NE, NYISO, SPP, and ERCOT rules modeled per-stage from published tariffs and business practice manuals.

"We built Zonevex because we watched a 200 MW solar project lose its queue position over a single unsigned parcel. The spreadsheet said 92% coverage. The RTO said 74%."

Frequently asked questions

What is FERC Order 2023 site control validation? +
FERC Order 2023 requires interconnection customers to demonstrate site control over the land where generation facilities will be built. Each RTO (PJM, MISO, CAISO, ISO-NE, NYISO, SPP) sets its own coverage thresholds at each queue milestone. Developers must prove they hold eligible instruments (leases, options, fee ownership, easements) covering a sufficient percentage of the project boundary at each stage.
What site control coverage thresholds do RTOs require? +
Thresholds vary by RTO and queue stage. For example, PJM requires 50% site control at application and 100% at IA execution. CAISO requires 90% at cluster study entry and 90% at IA execution (options excluded). MISO requires 75% at DPP Phase 1 and 100% at IA execution. ISO-NE, NYISO, and SPP each have their own stage-specific rules.
What are the 5 filters in a site control coverage audit? +
A complete site control audit checks five criteria: (1) Active status — the instrument has not expired or been terminated. (2) Eligible instrument type — the RTO accepts the instrument category at the current stage. (3) Encumbrance policy — mortgages, liens, or conservation easements do not block coverage per RTO rules. (4) Owner signature verification — all required owners have signed. (5) BLM ROW status — for federal land, the Bureau of Land Management right-of-way has reached the minimum required status.
How does Zonevex automate site control validation? +
Zonevex uses AI to extract legal descriptions, instrument types, expiration dates, and owner signatures from lease PDFs. It matches parsed descriptions to cadastral parcel boundaries using PostGIS spatial analysis, flagging overlaps, gaps, and encumbrances. Then it runs a stage-aware 5-filter coverage audit against each RTO's specific rules at every queue milestone, generating compliance reports with full audit trails.
What happens when an option-to-lease expires before a milestone? +
If an option-to-lease expires before a queue milestone (such as IA execution), the underlying acreage is excluded from the coverage calculation. This can drop total site control below the RTO's required threshold, potentially causing the interconnection request to be rejected. Zonevex sends milestone-aware alerts at 365, 180, 90, 60, 30, and 7 days before expiration to help teams convert or renew instruments in time.
Why do 77% of interconnection projects withdraw from the queue? +
According to Lawrence Berkeley National Laboratory, the primary drivers are high network upgrade costs, speculative applications, extended timelines (median 5 years to commercial operation), and cascading restudies when other projects withdraw. FERC Order 2023 adds site control demonstration as a new hard gate — projects that cannot prove compliant site control at each queue milestone are now automatically withdrawn. While site control is not the primary historical cause of withdrawals, the new requirements make it a compliance risk that developers must actively manage.
