01 / 13 · Mental Model
Start here. NYISO runs three auctions on top of one delivery system.
Every megawatt of power in New York moves through a single integrated wholesale market managed by NYISO, with three distinct products: energy, capacity, and ancillary services. Layered on top is a state policy regime run by NYSERDA and the PSC that adds incentive payments to projects supporting the state's clean-energy goals.
NYISO is a centralized auction market. Energy clears at LBMP nodes every 5 minutes. Capacity clears in monthly ICAP auctions against a sloped demand curve. Ancillary services co-optimize with energy. Above all that sits NYSERDA, which buys clean energy attributes through long-term contracts. Three layers, three pricing mechanisms.
Wholesale market — NYISO
Auction-based, public prices
Day-ahead and real-time energy markets clear at LBMP. Installed Capacity (ICAP) auctions clear monthly against state-approved sloped demand curves. Ancillary services co-optimize with energy in the day-ahead market.
The ISO is a buyer-of-last-resort for capacity through the spot auction. Prices are public. The auction is the price discovery mechanism.
State policy layer — NYSERDA / PSC
Long-term incentive contracts
NYSERDA buys Renewable Energy Certificates (RECs), Offshore Wind RECs (ORECs), and now Index Storage Credits (ISCs) through competitive solicitations. These are long-term (typically 20-year) contracts with fixed strike prices.
The Public Service Commission (PSC) sets retail tariffs, including VDER Value Stack for distributed energy. Together these layers make a project bankable.

02 / 13 · The Eleven Zones
NYISO divides the state into eleven load zones.
Where your project sits determines what you can earn. Zone matters for energy pricing (LBMP), capacity pricing (ICAP), and capacity-zone-specific reliability requirements.
BGenesee — Livonia is here. Rochester area, finger lakes. National Grid distribution.
CCentral — Syracuse is here. National Grid distribution.
AWest (Buffalo). Lowest LBMP zone historically.
DNorth. Hydro-rich (St. Lawrence). Often constrained.
EMohawk Valley. Utica corridor.
FCapital. Albany area.
GHudson Valley. Part of G-J Locality.
H, I, JMillwood, Dunwoodie, NYC. Highest LBMP and ICAP. Heavily constrained.
KLong Island (LIPA/PSEG-LI). Highest winter capacity prices statewide.
For your 2.5 MW project: Livonia is in Zone B; Syracuse is in Zone C. Both are upstate, both are National Grid territory, both have roughly similar LBMP profiles. Neither is in the G-J Locality, so neither earns the locational capacity premium that NYC and Long Island projects get.

03 / 13 · The Cast of Characters
Five entities run the show. Know what each one does.
New York's market structure has fewer institutional players than California, but the relationships among them matter.
01
NYISONew York Independent System Operator
Operates the wholesale energy market and the bulk transmission grid for all of New York State. Runs the day-ahead market (DAM) and real-time market (RTM) at LBMP nodes. Runs the ICAP market with monthly auctions. Co-optimizes ancillary services with energy. Located in Rensselaer, NY. The single source of truth for wholesale prices.
02
NY PSCNew York Public Service Commission
The state regulator. Sets retail rates, sets utility tariffs (including VDER Value Stack), oversees utility incentive programs, and approves NYSERDA program structures. The PSC issued the June 2024 Order that established the 6 GW storage by 2030 goal and authorized the new Index Storage Credit program.
03
NYSERDANew York State Energy Research and Development Authority
A public-benefit corporation that runs the state's clean energy programs. Procures Renewable Energy Certificates (RECs) through Tier 1, Tier 2, and Tier 4 RFPs. Procures Offshore Wind RECs (ORECs). Runs the Bulk Energy Storage Program (Index Storage Credits). Runs the Retail Storage Program (≤5 MW BTM rebates). Runs NY-Sun (community solar). The procurement counterparty for clean-energy projects.
04
Investor-Owned Utilities (IOUs)National Grid, NYSEG, RG&E, Central Hudson, Con Edison, O&R
Six investor-owned utilities own the distribution wires, deliver electricity to retail customers, and administer some incentive programs (e.g., Con Edison's Brooklyn-Queens Demand Management). For your project: both Livonia and Syracuse are National Grid distribution territory. Other upstate utilities are NYSEG (Avangrid) and RG&E (Avangrid). Long Island is served by LIPA / PSEG-Long Island (a public authority and contractor — not an IOU).
05
DPSNYS Department of Public Service
The staff arm of the PSC. Conducts reviews, manages dockets, and represents ratepayers in proceedings. When you read about a "Case 18-E-0130" or similar, that's a DPS docket number. The DPS document portal at documents.dps.ny.gov is the canonical source for filings, decisions, and tariff documents.
If you operate in California you may notice: New York has nothing equivalent to a CCA. The IOUs are still the LSEs for nearly everyone. ESCOs operate in the deregulated zones for retail competition, but they don't aggregate communities the way California CCAs do.

04 / 13 · The Three Wholesale Products
Three products. All run by NYISO. All public prices.
This is what a wholesale market looks like when one operator runs everything. Compare to CAISO, where capacity is bilateral and private.
A
EnergyDay-Ahead and Real-Time Market — LBMP at every node
Day-ahead market clears at noon the day before delivery. Real-time market clears every 5 minutes. Both produce a Locational Based Marginal Price (LBMP) at every node — congestion-aware nodal pricing. For a battery, the energy market is the venue for arbitrage: charge during low-LBMP hours, discharge during high-LBMP hours. NYISO publishes LBMP data on its OASIS site in near-real-time.
B
Ancillary ServicesCo-optimized with energy in the day-ahead market
NYISO procures Regulation Service, Spinning Reserves (10-min synchronized), Non-Synchronized Reserves (10-min non-sync), and 30-Minute Operating Reserves. Batteries qualify for all four products as Energy Storage Resources (ESR). Co-optimization means the day-ahead solution allocates a battery's capacity to whichever market (energy or AS) yields the highest combined value. Like CAISO, AS revenues have compressed as more batteries entered the market.
C
Capacity (ICAP)Monthly auctions against sloped demand curves
This is the structural difference from California. NYISO runs three capacity auctions: a six-month Strip Auction (Capability Period), monthly Reconfiguration Auctions, and a final mandatory Spot Auction 2-4 days before each delivery month. The Spot Auction sets the clearing price all participants pay or receive. Demand is administratively defined by a sloped curve set by the NYISO Board, refreshed every 4 years. Current cycle: 2025-2029.
The capacity period names matter: Summer Capability Period is May 1 through October 31. Winter Capability Period is November 1 through April 30. As of the 2025-2029 demand curve reset, NYISO uses separate seasonal demand curves — winter prices and summer prices are now independently calculated.
NYISO, "Installed Capacity Manual" (current version on dps.ny.gov); Modo Energy, "What NYISO's December capacity auction signals for batteries in 2025-2026," November 2025; ESAI Power, "NYISO Capacity Auctions Calendar," updated 20 January 2026.
How capacity prices are set. And why duration matters.
Two concepts you need to internalize: the sloped demand curve (how price clears) and the Capacity Accreditation Factor (how much UCAP your nameplate megawatts produce).
The sloped demand curve
NYISO does not let LSEs bid for capacity directly in the spot auction. Instead, the ISO submits monthly "bids" on behalf of all LSEs at a level set by the demand curve. This curve is a piecewise-linear function relating clearing price to the quantity of certified supply. When supply is abundant, prices are low; when supply is scarce, prices climb steeply. The curve is approved by the NYISO Board every four years. Current cycle: 2025-2029.
The Capacity Accreditation Factor (CAF) — and why duration matters
Starting with the 2024-2025 capability year, NYISO derates a resource's nameplate capacity into Unforced Capacity (UCAP) based on its expected availability during the highest-risk hour. For batteries, this means longer-duration systems get more credit per nameplate megawatt because they can sustain output through the entire grid-stress event.

6-hour battery
~0.90

For your 2.5 MW / 5 MWh (2-hour) project, the CAF derate puts you at roughly 1.25 MW UCAP for capacity revenue purposes. That's the number you should be using when modeling ICAP revenue, not the 2.5 MW nameplate. NYISO publishes seasonal CAF tables annually; the actual factor for your project depends on the year the battery enters commercial operation.
NYISO, ICAP Manual (current version); Modo Energy, "What NYISO's December capacity auction signals for batteries in 2025-2026," 20 November 2025 — confirmed seasonal demand curves split for 2025-2029 cycle and CAF table for storage durations.
06 / 13 · Capacity Zones & Recent Prices
Where you sit determines what you earn. NYISO uses three capacity zones.
Capacity prices clear separately in three zones, with the highest-cost zone (NYC, Long Island) reflecting the difficulty of building generation in heavily-constrained areas.

NYC vs Upstate Premium
~3×
NYC capacity prices typically 3× upstate (was 2.7×, narrowing to 1.7× this winter)
The locational premium is meaningful but not always huge. A 2.5 MW battery in Syracuse will earn far less per UCAP-MW than the same battery in NYC — but it will also cost much less to build, permit, and interconnect. The economics often favor upstate when you net it all out, especially with NYSERDA's Index Storage Credit available statewide.
Modo Energy, "What NYISO's December capacity auction signals for batteries in 2025-2026," 20 November 2025 — primary source for 2025-2029 demand curve scarcity caps. Recent spot auction price ranges are illustrative; check NYISO's ICAP Spot Market Auction Summary at icap.nyiso.com for current settled prices.
07 / 13 · NYSERDA Index Storage Credit
The state-level revenue anchor. This is what makes a project pencil.
For most upstate batteries, merchant revenues alone do not cover costs. The Index Storage Credit (ISC) is a contract-for-differences mechanism that closes the gap and provides 20-year revenue certainty.
How the ISC works — in one paragraph
You bid a fixed Strike Price ($/MWh of discharge) in a competitive solicitation. NYSERDA calculates a monthly Reference Price using two components: the Reference Capacity Price (RCP, derived from UCAP spot prices and your CAF) and the Reference Energy Arbitrage Price (REAP, derived from day-ahead zonal top-bottom spreads). When your Strike Price exceeds the Reference Price, NYSERDA pays you the difference. When it doesn't, you pay NYSERDA. You operate in the spot market normally and keep upside above the Reference Price.
This is structurally similar to how NYSERDA buys offshore wind through ORECs and large-scale renewable energy through Tier 1 RECs. Same contract-for-differences template, applied to storage. For someone familiar with REC economics, ISC will feel familiar.
The first solicitation just closed
ISCRFP25-1. Step One applications due August 2025. Step Two bids due 29 January 2026.
46 eligible projects bid, totaling ~6 GW power and ~30 GWh energy capacity.
Award target: ~1 GW. NYSERDA expects to announce winners and complete contracting in Q3 2026.
Bid scoring: 60% Strike Price, 20% Project Viability and Maturity, 10% Electricity System Value, 10% Societal and Economic Benefits.
Duration categories: 4-hour and longer is the primary category; 2-hour systems capped at 10% of total awards.
2-hour cap implication. Your 2.5 MW / 5 MWh (2-hour) project competes in the limited-allocation 2-hour bucket. Future ISCRFP rounds may have different structures.
What this means for Livonia or Syracuse
The upstate ISC opportunity
Upstate Reference Prices are lower than NYC Reference Prices — meaning the gap NYSERDA pays is larger for upstate projects with the same Strike Price. That makes upstate projects more attractive to NYSERDA from an ISC-cost perspective, all else equal. The trade-off: lower NYSERDA payment per MWh in absolute terms, balanced against lower CAPEX and faster permitting outside NYC.
Modo Energy reported in February 2026 that upstate REAP values stayed elevated after winter storms, persisting into spring. If that holds, upstate Reference Prices stay higher than expected, which compresses the gap between Strike Price and Reference Price — meaning developers in upstate zones can bid lower Strike Prices and remain competitive.
NYSERDA, "Bulk Energy Storage Program," https://www.nyserda.ny.gov/All-Programs/Energy-Storage-Program/Developers-and-Contractors/Bulk-Storage-Incentives — confirms 46 eligible bids, ~6 GW / 30 GWh, Q3 2026 award timing.

Compare to California: most NY programs are open. This is the structural reason a 2.5 MW battery in Livonia or Syracuse looks materially different from a 2.5 MW battery in Oroville. The ISC alone often closes the gap that would otherwise make an upstate NY project unbankable.

What a 2.5 MW battery actually earns. Year 1, illustrative, with ISC.
Mid-case assumptions for a 2.5 MW / 5 MWh project in Zone B (Livonia) or Zone C (Syracuse), with an ISC contract. These are illustrative numbers, not committed prices.
ISC Contract (NYSERDA)
$165,000 — Strike Price topping up Reference Price
Important caveat. These are illustrative numbers, not verified to a specific bid. The actual Strike Price for an ISC-contracted project depends on what you bid and what NYSERDA accepts. The realistic range for a 2-hour upstate project's combined revenue intensity sits roughly between $130 and $180/kW-yr depending on Strike Price discipline, capacity zone, and operational performance. Without an ISC contract, a merchant-only upstate 2-hour BESS would likely come in well below that, perhaps in the $80-110/kW-yr range.

10 / 13 · Interconnection & Permitting
Three doors. Plus a state-level permitting overlay.
For your 2.5 MW project, distribution-level interconnection through National Grid is the realistic pathway, with local permitting governed by town zoning and the NYS Uniform Fire Prevention and Building Code.
For projects up to 5 MW connecting to a utility's distribution wires. PSC-governed Standardized Interconnection Requirements apply uniformly across National Grid, NYSEG, RG&E, Central Hudson, Con Edison, and O&R. Pre-application screening, then CESIR (Coordinated Electric System Interconnection Review). Standard cost-causation principles. Your 2.5 MW project sits squarely in this lane.
For projects above the 5 MW SIR threshold but still distribution-connected. Some utilities have a separate "Large Generator" track. Costs are higher, studies are deeper, and there's typically more chance of distribution upgrades being assigned to the project.
D3
NYISO Bulk Power System InterconnectionFERC + NYISO · ≥20 MW typical · 36-60+ month timeline
For projects connecting at transmission voltages. Goes through the NYISO Class Year process, an annual cluster study with deliverability assessments and Network Upgrade cost allocation. Much longer queue, much more expensive, but enables full wholesale market participation including capacity market eligibility at scale.
Permitting and CLCPA siting
For a 2.5 MW battery, local zoning and building permits govern. The NYS Uniform Fire Prevention and Building Code (incorporating the 2023 edition of NFPA 855) became effective with the 2025 NYS Fire Code update. Required components include UL 9540A test results, peer-reviewed safety documentation, decommissioning plans, and emergency response plans coordinated with the local fire department.
For projects above 25 MW, the Office of Renewable Energy Siting (ORES) under Article VIII of NY Executive Law provides a streamlined state-level siting process that pre-empts local discretionary review. Below 25 MW, the project goes through standard Town or City SEQRA review. Your 2.5 MW project is well below the ORES threshold.
For Livonia (Town of Livonia, Livingston County) and Syracuse (City of Syracuse or surrounding towns in Onondaga County): each Town's Zoning Code dictates whether BESS is permitted by-right, by site plan review, or by special use permit. These rules vary by town; the relevant town code section is typically titled "Battery Energy Storage System" or "Energy Storage System" and was added in most NY towns between 2020 and 2024 in response to the model law published by NYSERDA.
NY PSC, Standardized Interconnection Requirements (current version on dps.ny.gov); NYSERDA, Model Battery Energy Storage System Law; NYS Uniform Code adoption of NFPA 855 (2023 edition) effective with 2025 NYS Fire Code update; ORES Article VIII Executive Law; NYSERDA, ISCRFP25-1 references peer review and UL 9540A as code compliance requirements.
11 / 13 · NYISO ↔ CAISO
Side by side. For your California-aware partners.
If your business partners are also reading the California field guide, this is the translation table.
Market Element
NYISO
CAISO
Energy market
LBMP day-ahead and real-time at ~500 nodes; 11 zones
LMP day-ahead (IFM) and real-time at ~3,000+ nodes; 3 trading hubs
R.25-08-004 (Rule 21); R.20-05-012 (SGIP); EDAM expansion; Slice-of-Day implementation
The biggest takeaway from the comparison: NYISO's market is more transparent (public auction prices, public CAF tables, public NYSERDA contract structures), while CAISO's is more opaque (bilateral RA, private contracts, retrospective price discovery). This is one reason upstate New York project finance is often easier than equivalent California project finance, despite California having larger absolute revenue numbers.

13 / 13 · Takeaways
Five things to remember when reading anything New York-related.
1
NYISO is centralized; CAISO is decentralizedMental model
When the headline says "NYISO did X" — that may mean any of energy, capacity, or ancillary services because NYISO runs all three. When the headline says "NYSERDA did Y" — that's a long-term contracting program, structurally separate from the wholesale market. Different layers, different timelines, different pricing.
2
Capacity prices are public. Watch the ICAP Spot Auction monthlyPrice discovery
Unlike CAISO's bilateral RA market, NYISO publishes ICAP spot auction clearing prices for all three zones (NYCA, G-J Locality, NYC, LI). These are at icap.nyiso.com. Modo Energy's monthly NYISO benchmarks are the best market-wide commentary; ESAI Power produces forecasts and pre-auction analysis.
CAF tables matter. A 2-hour battery gets ~50% UCAP credit; a 4-hour gets ~78%; a 6-hour gets ~90%. For ICAP economics, longer is worth more per nameplate MW. Your 2.5 MW / 5 MWh (2-hour) project is on the lower-CAF tier, but pairs with the structural advantage that 2-hour systems are cheaper to build and easier to permit.
4
The Index Storage Credit is the bankability anchor for upstateRevenue stack
Without an ISC contract, most upstate batteries do not pencil on merchant revenues alone. The ISC fills the gap between Strike Price and Reference Price, providing 20-year revenue certainty. The first solicitation just closed January 2026 with awards Q3 2026; subsequent rounds are expected through 2030. Your project should be positioned to bid in a future ISC round if not already contracted.
5
Local zoning and fire code compliance are real gating itemsPermitting
Below 25 MW, ORES does not apply; you go through Town SEQRA review. NFPA 855 (2023) is now part of the NYS Uniform Code via the 2025 Fire Code update, requiring UL 9540A test results, peer-reviewed safety documentation, and emergency response plans. Most NY towns adopted BESS-specific zoning between 2020 and 2024; the model law from NYSERDA is the template.
The shortest summary: read the NYISO ICAP spot auction monthly, track NYSERDA ISC solicitation calendars, verify your town's BESS zoning before site control, and check RPTL §487 opt-out status with the County Assessor. Those four disciplines cover 90% of the regulatory and commercial risk for any 2.5 MW NY project.
