The BAAS model

Battery capacity, delivered as a service.

BAAS structures project capital, delivers the system, and manages performance throughout the contract term.

A complete service model

One provider from development to operations.

The agreement defines capacity, economics, and responsibilities. BAAS manages the infrastructure and performance.

01

Project development

Define the requirement, site constraints, technical design, economics, and risk.

02

Capital structuring

Build a project-specific capital and payment structure—subject to underwriting.

03

System delivery

Integrate BESS, power conversion, controls, protection, testing, and commissioning.

04

Lifecycle operations

Manage dispatch, maintenance, warranties, degradation, reporting, and performance.

What the service defines

Define the service in five terms.

POWER

MW

Controllable charging or discharging power.

ENERGY

MWh

Usable stored energy and service duration.

READINESS

Availability

Service windows, maintenance allowances, and readiness.

SPEED

Response

Required timing for dispatch, transition, or resilience.

TERM

Lifecycle

Contract term, capacity retention, augmentation, and end-of-term treatment.

Traditional equipment purchase

Buy and assemble

  • Customer funds the equipment
  • Customer coordinates design and integration
  • Customer manages performance and degradation
  • Operating value depends on in-house capability

Battery as a Service

Contract for capacity and value

  • Project-specific capital structure
  • Integrated development and delivery
  • Defined responsibilities and performance
  • Long-term operating and asset management
Project-specific capital structures may reduce upfront investment, subject to underwriting, customer credit, contract term, and final agreements.

Commercial structures

Project-specific payment structures.

Capacity availability

Contracted capacity fee

Payments tied to MW, service windows, duration, response, and availability.

Shared value

Savings or revenue share

A measured share of savings, incremental revenue, or other verified value.

Hybrid

Fixed + variable

Capacity, energy, operations, and performance-based payments combined.

Battery as a Service

Define the capacity. Build the asset to deliver it.
