KERN (CA) · PGAE · node key ARCO · CAISO run date 2026-10-12

Seven questions a developer, lender or counsel asks before filing here. Every figure is a CAISO row; Not public marks what the public files cannot answer and where to get it. Definitions: methodology.

Can you get in?

No official Cluster 16 availability statement names this POI. Absence of a statement is not availability.

Not public: per-constraint transmission headroom at this POI — CAISO's cluster study reports (RIMS login).

Not on this site yet: the zonal transmission-capability table CAISO publishes for cluster scoring — public; the join is planned.

Who is ahead of you?

915 MW (n=5)

queued ahead of a new request (legacy + C15)

265 MW (n=3)

with an executed interconnection agreement · public report; C15 has no IA yet

60 MW (n=1)

operating at this node

0 MW

Cluster 15 requests seeking full capacity

Not public: who the interconnection customers are (the queue) — CAISO's public files carry project names only; the projects table below is the full public record. EIA-860 names the owners of what already operates nearby, not of what is queued.

Do projects leave after seeing the costs?

1,525 MW (n=14)

received Phase II / Facilities Study results here · any sheet, public report

550 MW (n=8)

of that, withdrew with results in hand

0.36 (n=14)

Phase II attrition (MW share)

Not public: the network upgrade cost allocated to a project here — Phase I / Phase II study reports, served through RIMS. Ask the incumbent developer or request the report; nothing public reconstructs it.

Will you be deliverable?

100 MW (n=1)

2025 TPD requested at this node

0 MW

allocated

100 MW

refused at 0 % — contracted / shortlisted (groups A+B)

0 MW

refused at 0 % — no PPA (group D)

0 / 1

2024 cycle: projects given full / partial capacity

A 0 % in group D is the expected result for an uncontracted project; a 0 % in group A or B is a contracted project that did not get deliverability. Rows are joined through all three sheets, so a request whose project has since withdrawn still appears. CAISO states no reason.

Will the power be worth anything here?

The Local Capacity Technical Report does not name this substation on any area boundary: not encoded, which is not the same as outside every area.

Not on this site yet: day-ahead price history at this POI — CAISO OASIS publishes it; it is shown only for a pricing node confirmed by hand in data/poi_pnodes.csv, and this one is not confirmed yet.

Will the land pass intake?

Intake scoring under the 2023 IPE rewards site control, permitting progress and system need before study begins. Parcel, zoning, Williamson Act and CEC exclusion screens run for Kings and Kern counties (caiso-siting parcels, layers screen); results are in outputs/parcels_*.md for the nodes they were run on and are not yet rendered per node here.

Not public: landowner willingness and option terms — county assessor parcels give ownership class, not intent; owner names are withheld on purpose.

How long, and who gave up?

300 MW (n=2)

withdrawn since 2022 (both reports)

300 MW

of that, storage

0.33 (n=8)

storage churn · withdrawn storage ÷ queued + operating storage

n/a (n=0)

Cluster 15 survival · active ÷ (active + withdrawn)

1,914 MW (n=18)

all-time withdrawn since 2006 · mostly wind/solar-era; colour, not signal

2026-12-01 to 2030-09-01

current on-line dates of active projects

Cluster-level time-to-withdrawal curves are on the Survival page; they compare process regimes, not only nodes.

Projects at this node (24)

Both reports. cod = current on-line date (public report) or proposed on-line date (Cluster 15). ia_status exists only in the public report. Cluster 15 deliverability is requested, not allocated.

TPD allocation requests at this node (2)

CAISO Transmission Plan Deliverability allocation results, joined on queue position through all three sheets of the public report (a request whose project has since withdrawn still appears). 2024 rows carry no MW. Groups: A = executed power purchase agreement requiring FCDS, or an LSE serving its own load; B = shortlisted for, or actively negotiating, a power purchase agreement; C = already in commercial operation for the capacity seeking TP deliverability; D = no PPA; electing the Section 8.9.2.3 (financial-security) path.

WDAT requests at this substation (3)

WDAT = distribution-level queue at the same substation, PG&E file today; not CAISO deliverability. WDAT requests connect below CAISO's transmission grid; they carry no CAISO deliverability unless separately studied.

`wd_recent_storage_mw`	300	storage MW of those rows — each project's storage components capped at its net-to-grid figure; a handful of filings report net-to-grid as 0 and keep the component MW, so this can exceed the row above at 3 nodes.

`p2_reached_mw`	1,525	MW of projects that received Phase II / Facilities Study results here (public report, any sheet)

`eia_storage_mwh`	0	battery energy capacity among them (EIA-860 Energy Storage file), as reported
`eia_storage_1h_mw`		storage MW at units whose reported MWh is no more than their MW (one hour or less); shown with 'duration not established' because the value may reflect how the form was filled
`eia_proposed_mw`	0	nameplate MW in EIA-860's Proposed sheet within the same radius (planned / under construction)
`wd_alltime_mw`	1,914	every withdrawn MW since 2006 (includes dead wind/solar-era projects)
`storage_churn`	0.33	wd_recent_storage_mw / (active + operating storage MW) — the one to quote
`churn_alltime`	1.96	wd_alltime_mw / (pipeline + operating MW) — historical color only
`c15_survival`	n/a	c15_active / (c15_active + c15_withdrawn)

`tpd25_denied_mw`	100	MW requested by rows that received 0 %
`tpd25_unalloc_mw`	100	requested minus allocated: MW refused outright PLUS the remainder left by partial allocations — quote this for 'what the developer did not get'
`tpd25_unknown_mw`	0	MW requested by rows with no allocation percentage in the file; 0 today
`tpd25_req_A_mw`	100	of tpd25_req_mw, requested in allocation group A: executed PPA (or LSE own load)
`tpd25_req_B_mw`	0	of tpd25_req_mw, requested in allocation group B: shortlisted / negotiating a PPA
`tpd25_req_C_mw`	0	of tpd25_req_mw, requested in allocation group C: already in commercial operation
`tpd25_req_D_mw`	0	of tpd25_req_mw, requested in allocation group D: no PPA, Section 8.9.2.3 path

`lcr_status`		CAISO Local Capacity Area (Resource Adequacy geography): 'in <area>' or 'outside <area>' as the LCT report's boundary lists state it; blank = not encoded, never 'outside every area'
`lcr_sub_area`		sub-area / load pocket within that area, when the LCT report delineates it
`wdat_active_projects`	0	active WDAT requests at the same substation (WDAT = distribution-level queue at the same substation, PG&E file today; not CAISO deliverability)
`wdat_active_mw`	0	MW of active WDAT (distribution-level) requests at the same substation (PG&E file today)
`wdat_active_storage_mw`	0	storage MW attributed from wdat_active_mw — an assumption: the PG&E file publishes one MW figure per request, so storage-only requests count in full and solar+storage requests count at half (160 of 1,011 active requests carry storage; 362 of their 479 MW is attributed as storage).
`wdat_inservice_mw`	0	WDAT MW already in service at that substation
`wdat_withdrawn_mw`	60	WDAT MW withdrawn at that substation (all-time in the file)
`wdat_ft_over_cap_n`	0	active Fast Track requests above the 5 MW Fast Track ceiling — held out of wdat_active_*
`wdat_ft_over_cap_mw`	0	MW of those held-out rows, as posted; cause not established
