  • Performance test validation
  • Quality assurance throughout project lifecycle

HOW WE SUPPORT YOUR PROJECT

At Every Stage of Development

Project Development

Energy Yield Assessment (EYA)

Independent, bankable energy yield studies for BESS assets, incorporating offtake conditions and market dynamics to provide accurate revenue projections—whether co-located with renewable generation or operating independently.

Owner's Engineering (OE)

Strategic technical guidance including:

  • Battery technology selection (LFP, NMC, and emerging chemistries)
  • Supplier evaluation and procurement support
  • System sizing and configuration optimization for retrofits or standalone installations
  • Electrical design review (layouts, single-line diagrams, grid connection)
  • Integration planning for existing renewable assets

Investment & Transaction Support

Technical Due Diligence (TDD)

Comprehensive technical risk assessment for acquisitions, financing, or refinancing decisions:

  • Regulatory and permitting compliance (hybrid retrofits vs. standalone configurations)
  • Technical design and equipment review
  • Electrical integration assessment for retrofit projects
  • Financial performance benchmarking
  • Contractual and offtake agreement analysis
  • Environmental and safety risk assessment
  • For early-stage assets: "Probability of success" scoring based on project maturity

Track Record:

1.5 GW of technical due diligence across renewable energy assets completed

Construction & Commissioning

Performance test validation

Rigorous commissioning verification:

  • Charge and discharge profile analysis
  • Cell, module, and rack-level performance testing
  • System integration verification (including hybrid system coordination for retrofits)
  • Warranty baseline documentation

Retrofit or Standalone?
We Cover Both

Retrofit Solutions

Add battery storage to your existing solar or wind farm to capture curtailed energy, optimize dispatch, and unlock new revenue streams.

Standalone BESS

Develop dedicated energy storage projects for grid services, arbitrage, or capacity markets.

Why Choose 8.2 Advisory?

Whether you're developing a new BESS project, retrofitting an existing renewable asset, optimizing operations, or evaluating an investment opportunity, our independent expertise helps you make informed decisions and maximize the value of your energy storage investment.
