FERC Order 2023 changed the rules
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 Projects that can’t prove compliance get withdrawn automatically.

$200K
sunk cost per abandoned MW of development
For a typical 150 MW project, that’s $30M in development spend that evaporates if site control drops below threshold. An expired option, a missing signature, or an unresolved encumbrance is all it takes.

2026 is the year every RTO runs reformed cluster studies simultaneously. PJM Cycle 1 applications open April 27 — a single annual intake window. CAISO Cluster 16 opens October 1. MISO's DPP-2025 launched in January. Miss the window or submit with incomplete site control, and you wait until 2027.
The stakes are no longer abstract. Deposits now escalate to 20% of network upgrade costs at LGIA execution. For a 200 MW solar project, that's $10M+ at risk. The LBNL Queued Up 2025 report found that 77% of interconnection requests withdraw and only 13% reach commercial operation. Order 2023's readiness requirements are designed to push that withdrawal rate even higher — and earlier.
In the first half of 2025, $22 billion in renewable projects were canceled, averaging $200K in sunk costs per abandoned MW. The transition period is over. The new process is the process. No existing land management platform runs stage-aware coverage audits with the 5 filters RTOs actually check.
Field note: option-to-lease weighting is a frequent surprise. CAISO discounts options to 0.75 starting at the Facilities Study and excludes them entirely at IA execution. PJM accepts options at application but treats Manual 14H attestation as a hard gate at every Decision Point. Most spreadsheets count both at 100%, which is why stated coverage and RTO-effective coverage diverge well before any milestone fails.
Read the full 2026 compliance analysis →FERC Order 2023 applies to every generator interconnection — solar, wind, gas, storage, and hybrid. 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.

Development finance & diligence
Verifying site control coverage during acquisition, financing, or partnership review
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.
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.
PJM requires 100% at application per Manual 14H. CAISO requires 90% at cluster study. Spreadsheets can't track stage-aware rules across 7 markets. One wrong number = rejected filing.
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.
Four layers of hard engineering that you can't replicate in a spreadsheet.
Upload lease PDFs. AI extracts legal descriptions, instrument types, expiration dates, option deadlines, and owner signatures from unstructured legal documents.
PostGIS matches metes-and-bounds and lot descriptions against county cadastral boundaries. Overlaps, gaps, and encumbrances are flagged automatically.
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.
Active status, instrument eligibility, encumbrances, owner signatures, and BLM ROW status — checked per stage. Pass or fail, with every exclusion documented.
A design-partner engagement returns a per-project risk grade, parcel-level findings citing the rule that triggered each one, milestone-aware exposure calendar, and an auditable history your compliance team and lenders can reference. PDF + Excel, refreshed as your portfolio changes.
Documents reviewed under mutual NDA. Encrypted in transit and at rest. Per-tenant isolation enforced at the database layer. Customer documents are never used to train models.
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.
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.
Generate RTO-formatted compliance packages with parcel coverage, instrument detail, exclusion justifications, and BLM/encumbrance status. PJM, MISO, CAISO, ISO-NE, NYISO, SPP, and ERCOT formats supported.
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.
Most developers don’t pick one of these — they run three or four simultaneously. A portfolio spreadsheet for tracking, an in-house PostGIS analyst for the spatial work, outside consultants for capacity gaps, and legal or PE review per filing because regulators require it. The question isn’t which to choose; it’s where automated reconciliation reduces the work each is doing.

Sources & methodology
[1] RTO rules sourced from published tariffs and business practice manuals: PJM Manual 14H, CAISO Conformed Tariff, MISO BPM-015, ISO-NE Tariff, NYISO Tariff, SPP Open Access Transmission Tariff.
[2] GIS / compliance consulting hourly rates are typical of the engineering-services band published in ACEC Research Institute fee surveys and similar industry references. Per-engagement scope (and total cost) varies widely between a scoping audit on one project and a full multi-RTO portfolio review.
[3] Spreadsheet failure modes in regulated industries are catalogued by the European Spreadsheet Risk Interest Group (EuSpRIG), including direct utility-sector cases — the TransAlta C$24M power-trading copy-paste error being the most-cited. The structural risks (manual data entry, no spatial reconciliation, no version-controlled instrument history, version drift between team members) apply directly to multi-project site control tracking even where it hasn’t been studied as its own population.
[4] All-in annual cost for one senior PostGIS / GIS engineer in the U.S. energy market. Base salary $160–220K — BLS OEWS for cartographers/photogrammetrists (17-1021) and geographers (19-3092) as floors; senior energy/RTO-experienced roles in NYC/SF/DC sit at the upper end per Robert Half’s Tech Salary Guide. Employer-paid benefits $40–65K — FICA (~7.65%), health insurance employer share ($15–22K family), 401(k) match (4–6%), PTO accrual, life/dental/disability, workers comp. Software/tooling $10–25K — ESRI ArcGIS Pro Professional ($2,375/yr/seat), Spatial Analyst & other extensions, PostGIS-capable database hosting ($300–1,000/mo), Microsoft 365, conference and training. Overhead $5–15K — equipment, IT support, recruiting amortization. Total all-in: ~$215–325K/yr; cell range rounds to $200–300K.
[5] Per-filing legal and PE review is required for FERC Order 2023 / RTO submissions and remains so regardless of any tooling layer. Cost varies materially by firm, scope, project size, and prior precedent.

We publish ranges only when we can substantiate them.
Scope of this comparison: the in-house, consulting, and review capacity most developers stitch together today. It does not compare to direct vendor alternatives (other site control or land-management platforms); those comparisons are out of scope here.
