USE CASES

ANALYZE UNLIMITED REVENUE STREAMS AND INCENTIVES WITH FRACTAL MODEL

Analyzing the intricate revenue stacks of today’s industry requires more than a spreadsheet; it requires a sophisticated physics and financial engine. Fractal Model is designed specifically to bridge the gap between complex grid engineering and investment-grade financial analysis. The modern BESS business case is a “layer cake” of contracted revenue, market merchant upside, and incentives. Fractal Model allows users to simulate how a battery can simultaneously optimize revenue across these streams while accounting for technical (losses, degradation, aux load, warranty, etc.).

MECHANT USE CASES

In a merchant model, the project is fully exposed to market prices. This offers the highest potential IRRs but carries the most risk.

  • Energy Arbitrage (DA/RT): Buying low and selling high. In Day-Ahead (DA) markets, you hedge your position based on forecasts; in Real-Time (RT) markets, you capitalize on sudden price spikes caused by grid stress or renewable intermittency.
  • Ancillary Services: Each market offers a unique blend of available ancillary services, each with unique qualification and participation requirements, forecasted clearing prices, physical obligations, and market competition.
  • Capacity Markets: Payments for simply being available to ensure grid reliability (e.g., PJM’s RPM or ISO-NE’s Forward Capacity Market), that can be further assesed based on a capacity accreditation or Effective Load Carrying Capability (ELCC) methodology.

QUASI-MERCHANT USE CASES

These structures are designed to satisfy bankability requirements while keeping a foot in the merchant door.

  • Split Capacity: You might contract 50% of the battery’s output to a utility (Fixed) and leave the other 50% to trade in the merchant market.
  • Merchant Tail: A project is fully contracted for the first 10–12 years to pay off the debt, after which it operates as a pure merchant asset for the remainder of its useful life (usually years 12–20).

FULLY-CONTRACTED USE CASES

This is the preferred route for conservative investors and financiers seeking stable, returns.

  • Resource Adequacy (RA) Contracts: Load-Serving Entities (LSEs) pay BESS owners fixed monthly capacity payment ($/kW-month) for the “Net Qualifying Capacity” (NQC) of the battery to ensure grid reliability during peak or “Slice-of-Day” hours.
  • Tolling Agreement: An off-taker (utility or IPP) pays a fixed “capacity charge” to have exclusive rights to charge and discharge the battery. They take the market risk; you take the operational risk.
  • Energy Storage Service Agreement (ESSA): Similar to a PPA, the off-taker pays for the services provided by the BESS, often including specific performance guarantees for energy throughput and efficiency.

FINANCIAL HEDGES / INSURANCE PUTS

These are third-party financial products used to floor the downside.

  • Revenue Floor / Revenue Exchange: A bank or insurance company guarantees a minimum annual revenue. If the market underperforms, they pay you; if it outperforms, you share the “upside” with them.
  • Insurance Put: A financial derivative that protects against “low volatility” years. Since batteries thrive on price spreads, a stable market is actually a risk; the Put pays out if price spreads stay below a certain threshold.

PROGRAMS AND INCENTIVES

Illinois: The Clean and Reliable Grid Affordability Act (CRGA)

Illinois has quickly become the most sought-after market in the Midwest. Under the CRGA (signed January 2026), the state is moving toward a 3,000 MW storage target with fixed-price protection.

Section 48 Investment Tax Credit (ITC)

  • Base Credit 30% ITC: Available for projects that meet Prevailing Wage and Apprenticeship, and steel requirements.
  • Bonus Domestic Content (+10%): Requires a specific percentage of the total cost of manufactured products (e.g., battery cells/modules) to be produced in the U.S. meets the annual threshold.
  • Bonus Energy Community (+10%): Applied if the project is located in a brownfield site or a census tract significantly impacted by the retirement of coal mines or coal-fired power plants.
  • Low-Income / Environmental Justice (+10% or +20%): A competitive allocation for projects that directly benefit disadvantaged communities (low income, Indian land).

New York Index Storage Credits (ISC)

  • The New York Index Storage Credit (ISC) is a state-level procurement mechanism designed to provide long-term revenue certainty by hedging the difference between a project’s bid price and volatile wholesale market revenues.

    • Contract Term: 15 Years.

Maryland: Next Generation Energy Act (NGEA)

Maryland has transitioned to a “Capacity Credit” model to ensure the state meets its aggressive decarbonization goals without solely relying on volatile PJM price signals.
