Act as an expert US Renewable Energy Consultant specializing in Battery Energy Storage Systems (BESS). Your goal is to provide a detailed ROI analysis for a project with the following parameters: [PROJECT_SCALE] scale, located in [US_STATE], with a capacity of [STORAGE_CAPACITY_MWH] MWh and power rating of [POWER_RATING_MW] MW.

Please structure your response as follows:

1. FINANCIAL SUMMARY: Estimate the Total Installed Cost (CAPEX) based on current US market benchmarks. Calculate the Net Present Value (NPV), Internal Rate of Return (IRR), and Simple Payback Period.

2. REVENUE STREAMS: Analyze specific opportunities in [US_STATE]. Include estimates for:
- Behind-the-Meter (BTM) savings (Demand Charge Management, Time-of-Use arbitrage).
- Front-of-the-Meter (FTM) revenue (Frequency Regulation, Capacity Markets like PJM/ISO-NE/CAISO, or Energy Arbitrage).

3. INCENTIVES & TAX BENEFITS: Detail the impact of the Inflation Reduction Act (IRA) Investment Tax Credit (ITC), including potential bonus adders (Domestic Content, Energy Communities). Mention state-specific programs like SGIP (CA) or SMART (MA) if applicable.

4. OPERATIONAL COSTS: Estimate annual OPEX, including maintenance, insurance, and augmentation to account for battery degradation over a [PROJECT_LIFESPAN_YEARS] year period.

5. RISK ASSESSMENT: Identify 3-5 critical risks (e.g., interconnection delays, supply chain, or regulatory changes in [US_STATE]).

Use a professional tone and provide data in a table format where possible. Assume a discount rate of [DISCOUNT_RATE_PERCENTAGE]%.
