NYC Zone J Capacity Hit $32.6/kW-month Summer 2026: Zone J Grows and Retail

The May 2026 record clear

Modo Energy reported New York City Zone J monthly spot capacity auctions cleared at $32.6/kW-month in May 2026 and $32.5/kW-month in June 2026, a record about 67% above the zone's previous high and more than double May-June 2025 levels [modo-nyc-capacity-2026]. Rest-of-state zones cleared near $8/kW-month in the same period [modo-nyc-capacity-2026].

The summer capability period starts May 1 each year under NYISO rules [nyiso-icam]. Supply contracts tied to NYC ICAP reset on that date.

Why Zone J spiked

Three forces converged [modo-nyc-capacity-2026]:

Requirement step-up. NYC unforced capacity requirement rose about 435 MW to 8,486 MW at the May 1 reset. Locational Capacity Requirement in Zone J stepped from 78.5% to 82.6%.

Supply down. Awarded in-city capacity fell about 617 MW between periods as thermal plants derated in summer heat.

CHPE timing. The 1,250 MW Champlain Hudson Power Express line reached commercial operation May 13 but missed NYISO's notice deadline for the May capacity auction, so it could not count as in-city supply until July [modo-chpe-july-2026].

Modo noted NYC cleared at the ICAP reference point with no surplus in summer versus about 1,050 MW surplus near $6/kW-month in winter [modo-nyc-capacity-2026].

Locational Capacity Requirement math on a Queens canopy meter

NYISO assigns each zone a Locational Capacity Requirement expressed as a percentage of the statewide unforced capacity obligation [modo-nyc-capacity-2026]. Zone J's LCR stepped from 78.5% to 82.6% at the May 1, 2026 capability reset while the NYC unforced requirement rose about 435 MW to 8,486 MW [modo-nyc-capacity-2026]. More obligation must be procured inside city boundaries even when statewide supply looks adequate.

You do not calculate LCR on your bill directly. Your supplier assigns an ICAP tag in kW based on peak contribution and account history. The LCR step-up raises clearing prices when in-city supply falls short, which is what pushed May clears to $32.59/kW-month [modo-nyc-capacity-2026].

Illustrative ICAP stack for two operators in the same building class:

Facility	ICAP tag	May 2026 UCAP	Monthly ICAP	Summer four months
Micro-cultivation 220 kW	220 kW	$32.59	$7,170	$28,680
Dispensary 85 kW	85 kW	$32.59	$2,770	$11,080

Same UCAP price, different tags. A dispensary avoiding grow lights still pays Zone J locational scarcity because the market clears tight, not because your license type triggers a surcharge.

Compare upstate: $8/kW-month rest-of-state clear in the same period [modo-nyc-capacity-2026]. The 220 kW grow saves roughly ($32.59 − $8) × 220 × 4 ≈ $21,640 in summer ICAP alone by siting outside Zone J, before rent and delivery differences. CHPE's July qualification at $12.41/kW-month [modo-chpe-july-2026] narrows but does not erase that spread for May through June bills already locked at the record clear.

What $32.59/kW-month means on a bill

NYISO expresses capacity as $/kW-month (UCAP). Suppliers multiply your ICAP obligation (kW) by the clearing price for the capability period.

Assume a Queens cultivation facility with 350 kW ICAP obligation for summer 2026 at $32.59/kW-month [modo-nyc-capacity-2026]:

Period	Calculation	Monthly ICAP cost
One month	350 kW × $32.59	~$11,407
Four-month summer (May-Aug)	× 4	~$45,628

Annualize against 900,000 kWh summer use: capacity alone adds roughly 5.1 ¢/kWh if concentrated in four months (illustrative; suppliers may smooth differently).

A Manhattan dispensary with 120 kW ICAP at the same price pays about $3,911 per month in capacity pass-through before energy and Con Edison delivery.

Zone J cannabis operators: cultivation vs retail

Indoor cultivation in NYC is rare but permitted in limited zones. High kW from horticultural lighting stacks ICAP obligation. Demand charges on Con Edison SC8 or similar tariffs add delivery-side kW charges on top of ICAP.

Retail dispensaries use less kW per square foot than flower rooms but run long hours for HVAC, security, and refrigeration. ICAP still scales with peak contribution.

Microbusinesses combining retail and small canopy face both load profiles on one meter unless submetered.

July relief when CHPE qualified

Modo reported NYC UCAP fell about 62% from June to $12.41/kW-month in July 2026 when CHPE could first offer capacity [modo-chpe-july-2026]. Capacity's share of NYC's battery reference price dropped from 87% in May to 42% in July [modo-chpe-july-2026].

Operators who fixed supply at May peak ICAP may have overpaid relative to July clears unless their contract reprices monthly. Operators who floated ICAP saw a mid-summer step down.

Contracting in NYISO capability periods

NYISO resets capability periods May 1 (summer) and November 1 (winter) [nyiso-icam]. Cannabis operators should:

Shop supply before April for summer ICAP exposure.

Ask suppliers whether ICAP is fixed, monthly spot, or blended.

Compare New York electric choice quotes on identical ICAP assignment assumptions.

Budget separate lines for Con Edison delivery, NYISO energy, and NYISO capacity.

Structural takeaway beyond CHPE

CHPE's delay was a one-time timing story [modo-nyc-capacity-2026]. The underlying Zone J constraint remains: higher locational requirements and aging in-city thermal fleet. Indian Point retirement still echoes in downstate capacity planning.

Cultivators evaluating NYC versus Hudson Valley or upstate sites should model ICAP differential, not only Con Edison delivery rates. A lower rent lease in Zone J can lose to $20+/kW-month capacity spreads versus upstate.

After summer 2026

Track whether ICAP stays near July's $12/kW-month level or re-tightens if imports derate or requirements step again [modo-chpe-july-2026]. NYISO's demand curve reset to a two-hour battery reference unit also lifts reference prices in tight conditions (see related post on demand curve reform).

Confirm ICAP assignment with your supplier each capability period. NYC capacity is no longer a footnote on cannabis pro formas; it can exceed horticultural lighting kWh cost per dollar of revenue in peak months.

Con Edison delivery demand plus ICAP: two peaks, two charges

Zone J ICAP pass-through hits the supply invoice. Con Edison delivery demand on schedules like SC8 or SC9 hits the utility bill separately [modo-nyc-capacity-2026] [nyiso-icam]. A Queens indoor facility can set a billing peak when lights flip on while also carrying a high ICAP tag tied to summer capability period assignment [modo-nyc-capacity-2026].

Assume 280 kW ICAP tag and $32.59/kW-month UCAP in May 2026 [modo-nyc-capacity-2026], plus Con Edison delivery demand charge of $35/kW-month (illustrative tariff input):

Charge type	Monthly at 280 kW	Who bills it
ICAP (supply)	$9,125	Retail supplier or ESCO [nyiso-icam]
Delivery demand (utility)	$9,800	Con Edison [modo-nyc-capacity-2026]
Combined kW-based	$18,925	Two invoices

Staggering one flower room flip from 2 p.m. to 9 p.m. might trim delivery demand without moving ICAP if the tag was set on a prior capability period peak. Conversely, a new capability period can reset ICAP assignment while delivery ratchets still reflect last summer [nyiso-icam]. Track both peaks on interval data.

Microbusiness licenses combining limited canopy and retail on one meter blend horticultural and refrigeration load profiles [modo-nyc-capacity-2026]. ICAP scales with meter peak contribution, not license category. A microbusiness with 180 kW ICAP at May clear pays 180 × $32.59 ≈ $5,866 per month in capacity alone [modo-nyc-capacity-2026], before Con Edison delivery and supply energy.

CHPE's July 2026 qualification at $12.41/kW-month shows how fast NYC UCAP can move when in-city supply enters [modo-chpe-july-2026]. Budget May through June at the record clear even if forward curves soften later [modo-chpe-july-2026]. Shop supply in April for May 1 capability reset, not after the first high ICAP invoice arrives [nyiso-icam].

Upstate and Long Island spreads for multi-site operators

Modo Energy reported rest-of-state zones cleared near $8/kW-month while Zone J hit $32.6/kW-month in May 2026 [modo-nyc-capacity-2026]. Long Island cleared about $11/kW-month in the same period [modo-nyc-capacity-2026]. A 250 kW ICAP tag therefore carries wildly different summer capacity depending on meter location:

Location	May 2026 UCAP	Monthly ICAP on 250 kW	Four-month summer
Zone J NYC	$32.59 [modo-nyc-capacity-2026]	$8,148	$32,592
Long Island	~$11 [modo-nyc-capacity-2026]	$2,750	$11,000
Upstate ROS	~$8 [modo-nyc-capacity-2026]	$2,000	$8,000

Site selection for new canopy should model ICAP differential alongside rent and labor [modo-nyc-capacity-2026]. Indian Point retirement and higher locational requirements still constrain downstate supply even after CHPE entered [modo-chpe-july-2026] [nyiso-icam]. Fixed supplier quotes that assume July's $12.41/kW-month for the full capability period understate May through June exposure already billed at the record clear [modo-chpe-july-2026].

Modo noted NYC cleared at the ICAP reference point with no surplus in summer versus about 1,050 MW surplus near $6/kW-month in winter [modo-nyc-capacity-2026]. Capability periods reset May 1 and November 1 [nyiso-icam]. Shop downstate supply in April and October so ICAP assumptions match the next four-month window, not last year's winter surplus pricing [modo-nyc-capacity-2026]. The 1,250 MW Champlain Hudson Power Express line energized May 13 but missed the May auction deadline, which is why summer clears stayed elevated until July qualification [modo-chpe-july-2026].
