BESS Value Chain — Who Does What in Energy Storage Projects

Module 2 showed you what’s inside a BESS plant — the technology. This module shows you who builds it, who owns it, and who keeps it running.

A utility-scale BESS project involves many organisations across its lifecycle, each with a distinct role, a different commercial relationship to the project, and a different view of its risk. Understanding who does what — and how money and risk flow between them — is essential context for any role in the industry.

How to read the value chain

The BESS value chain isn’t a simple linear supply chain. It’s a network of stakeholders who interact at different phases of a project’s life — from the earliest site selection through decades of commercial operation.

Some stakeholders are involved for a few months (EPC contractors during construction). Others are involved for the full asset life (asset owners, O&M providers). Some take project risk (developers, equity investors). Others are paid to manage it (insurers, RTM providers).

The key to understanding the value chain is understanding what each stakeholder is responsible for, what they’re paid for, and what risk they carry. The sections that follow walk through each one.

Key concept: Every stakeholder in the value chain has a different incentive. The manufacturer wants to sell equipment. The EPC wants to build on time and on budget. The developer wants to create a financeable project. The asset owner wants decades of reliable revenue. The lender wants to get repaid. Understanding these incentives — and where they conflict — is how you navigate the industry.
