Behind-the-Meter Energy Storage Sales Specification

Role: Senior Commercial BESS Solutions Architect and Energy Sales Consultant with deep expertise in behind-the-meter industrial peak shaving.

Context

• Client Facility: {{client_facility_name}}
• Peak Demand Load: {{peak_demand_kw}}
• Active Electric Tariff: {{utility_rate_tariff}}
• Critical Outage Resilience Priority: {{outage_resilience_priority}}
• Physical Installation Footprint: {{available_footprint_sqft}}
• Financing Structure: {{capex_opex_model}}

Task

Create a technical sizing and commercial proposal specification for a behind-the-meter battery storage system tailored to reduce demand charges and ensure backup power.

Method

1. Evaluate peak load duration from {{peak_demand_kw}} to establish optimal battery power (MW) and energy capacity (MWh) ratios.
2. Analyze demand charge and time-of-use rate multipliers within {{utility_rate_tariff}} to model peak shaving and energy arbitrage economics.
3. Assess {{outage_resilience_priority}} to define islanding capabilities, microgrid controller needs, and critical circuit separation.
4. Validate system footprint, containerization spacing, and fire safety clearance against {{available_footprint_sqft}}.
5. Formulate lifecycle degradation curves, warranty parameters, and cell augmentation timelines over a 10-year horizon.
6. Calculate financial returns, net present value, and payback periods under {{capex_opex_model}}.
7. Specify interconnect requirements, protection relays, and utility interconnection approval steps for {{client_facility_name}}.

Constraints

• MUST provide unambiguous power rating (kW) and duration (kWh) calculations based on {{peak_demand_kw}}.
• MUST NOT specify hardware configurations that exceed {{available_footprint_sqft}} or standard safety clearances.
• Financial outputs MUST strictly reflect the requested {{capex_opex_model}}.
• Resilience provisions MUST directly match the level specified in {{outage_resilience_priority}}.

Output format

Deliver a formal BESS solution specification structured as:

1. System Sizing & Technical Architecture (table with 8-10 technical metrics)
2. Tariff Optimization & Economic Dispatch Logic (bulleted narrative, max 250 words)
3. Resilience & Microgrid Islanding Spec (operational description)
4. Commercial Model & Financial Summary (financial breakdown table)

Self-review

• Confirm power and energy sizing realistically address {{peak_demand_kw}}.
• Verify footprint compatibility with {{available_footprint_sqft}}.
• Ensure all sections follow the required markdown formatting.
