Project Financing of Battery Storage

Module 1: BESS Fundamentals, European Market Overview, Revenue Stacking & Trading

• Understanding the fundamentals of BESS as an asset class Benefits of integrating BESS in our energy system

• Distinguishing renewables and BESS from a financing perspective

• BESS revenue applications and value drivers

• Understanding why revenue quality drives bankability

• Identifying specific complexities of BESS financing

European BESS Market Overview

• Capex and regulatory drivers shaping BESS development

• Installed capacity and projected growth rate

• Comparison of maturity, grid regime and attractiveness across main European BESS markets

• Equity investor perspective on BESS

BESS revenue stacking & trading fundamentals

• Understanding the difference between ancillary services markets, wholesale energy markets and capacity markets

• Learn how batteries optimise revenues via cross market trading

Practical exercise: Assessing revenue forecasts and revenue stacks from a debt and equity perspective

Module 2: Inside the Credit Committee: Key risks and mitigants in BESS project financing

• A comprehensive walkthrough of the principal lender risk considerations in BESS financing, alongside inherent mitigants and additional structural protections which can increase the strength of the credit profiles, including Revenue volatility and saturation risk

• Optimiser and optimisation risk

• Regulatory, policy and market design risk

• Grid: positioning of BESS, operational constraints and grid fees

• Contractual risks

• Technology risks

• Obsolescence risk

• Supply chain and delivery risks

Practical exercise: Mitigating risks via financial structuring techniques (Participants will be presented with four scenarios to evaluate, for which they will be asked to identify and recommend appropriate financial risk mitigation strategies)

Module 3 — Contractual set-up, warranties, guarantees and cycling

• Walk through of typical contractual set-up for BESS project financing

• How key risks are allocated amongst project parties

• Demystifying key technical concepts (dduration, SoC, SoH, RTE, degradation and augmentation, BESS chemistry)

• Market standard BESS warranty and guarantee frameworks

• Understanding the interrelation between cycling limits and battery warranties

• Practical exercise: devising credit mitigation tools for overcycling

Module 4 —Revenue Models & Offtake Structures

• Choosing a suitable revenue and route-to-market model

• Fully merchant optimisation – advantages and disadvantages

• How to integrate capacity market and subsidy revenues into a BESS revenue stack

• Optimiser floor arrangements

• Explanation of different types of tolling: physical, virtual, financial and partial

• Revenue sharing and payout models

• Proxy hedging swap/toll structures

• Bankability assessment of revenue models

• Case Study: ‘’Designing an optimum offtake and financing structure’’ (On the basis of a given fact pattern participants will discuss, determine and defend the most appropriate route to market and financing structure for that specific scenario)

Module 5 - Hybridisation / colocation (renewables and BESS)

• Understanding the economic drivers for, and challenges with, hybridization, analysing different hybridisation business models and how to tailor your financing approach to each model

• Revenue optimisation variables for hybridised assets

• Grey/green storage concepts

• Hybrid PPA delivery models

• Load shifting and peak shaving

• Financing approach per model

• European overview per market

• Quiz: mapping contract designs to offtaker demand

• Deep dive: Co-located PV and storage – profiled PPA plus optimisation

Module 6 — Due Diligence, Negotiation and Reporting

• Review of the key topics for assessment across technical, legal and market due diligence

• Mapping revenue /market due diligence to specific financing case

• Information reporting requirements

• Common areas of lender / investor negotiation

Module 7 – From Concept to Contract: Putting Battery Finance into Practice

• Based on a high-level debt term sheet, participants will evaluate whether to grant project financing and under which terms and conditions

• This requires identifying the strengths and weaknesses of the business case, and, where relevant, proposing the inclusion of suitable credit mitigation measures

Training Objectives

• Understand how battery energy storage systems (BESS) function as an asset class, and how they differ from traditional renewable assets.

• Analyse revenue streams, market dynamics and revenue stacking mechanisms, and assess the robustness of revenue forecasts used in financing.

• Identify the principal risks in BESS project financing—including market, technical, regulatory and operational risks—and determine appropriate mitigation strategies.

• Evaluate different route-to-market and offtake structures and their impact on bankability and financing terms.

• Assess contractual frameworks, warranty structures and key technical considerations to understand their implications for lender risk allocation.

• Compare financing approaches for standalone versus co-located (hybrid) battery projects and the key drivers influencing structuring decisions.

• Apply a lender’s perspective to due diligence, negotiation and credit analysis, and form views on suitable financing terms and conditions.

• Demonstrate the ability to identify strengths and weaknesses in a BESS business case and formulate practical, transaction-ready credit recommendations.

Training Course Summary

This practical, executive-level course is designed for investors, developers, lenders, offtakers, suppliers and advisers seeking a better understanding of project financing within the battery storage sector.

Going well beyond theory, participants will benefit from real-life case studies, scenarios and practical examples to build an end-to-end understanding of the issues, risks, and considerations that lenders encounter across the lifecycle of BESS transactions.
